text: The cause of a twinned rainbow is believed to be the combination of different sizes of water drops falling from the sky. Due to air resistance, raindrops flatten as they fall, and flattening is more prominent in larger water drops. When two rain showers with different-sized raindrops combine, they each produce slightly different rainbows which may combine and form a twinned rainbow.


title: Rainbow

text: A numerical ray tracing study showed that a twinned rainbow on a photo could be explained by a mixture of 0.40 and 0.45 mm droplets. That small difference in droplet size resulted in a small difference in flattening of the droplet shape, and a large difference in flattening of the rainbow top.


title: Rainbow

text: Meanwhile, the even rarer case of a rainbow split into three branches was observed and photographed in nature.


title: Rainbow

text: In theory, every rainbow is a circle, but from the ground, usually only its upper half can be seen. Since the rainbow's centre is diametrically opposed to the Sun's position in the sky, more of the circle comes into view as the sun approaches the horizon, meaning that the largest section of the circle normally seen is about 50% during sunset or sunrise. Viewing the rainbow's lower half requires the presence of water droplets "below" the observer's horizon, as well as sunlight that is able to reach them. These requirements are not usually met when the viewer is at ground level, either because droplets are absent in the required position, or because the sunlight is obstructed by the landscape behind the observer. From a high viewpoint such as a high building or an aircraft, however, the requirements can be met and the full-circle rainbow can be seen. Like a partial rainbow, the circular rainbow can have a secondary bow or supernumerary bows as well. It is possible to produce the full circle when standing on the ground, for example by spraying a water mist from a garden hose while facing away from the sun.


title: Rainbow

text: A circular rainbow should not be confused with the glory, which is much smaller in diameter and is created by different optical processes. In the right circumstances, a glory and a (circular) rainbow or fog bow can occur together. Another atmospheric phenomenon that may be mistaken for a "circular rainbow" is the 22° halo, which is caused by ice crystals rather than liquid water droplets, and is located around the Sun (or Moon), not opposite it.


title: Rainbow

text: In certain circumstances, one or several narrow, faintly coloured bands can be seen bordering the violet edge of a rainbow; i.e., inside the primary bow or, much more rarely, outside the secondary. These extra bands are called "supernumerary rainbows" or "supernumerary bands"; together with the rainbow itself the phenomenon is also known as a "stacker rainbow". The supernumerary bows are slightly detached from the main bow, become successively fainter along with their distance from it, and have pastel colours (consisting mainly of pink, purple and green hues) rather than the usual spectrum pattern. The effect becomes apparent when water droplets are involved that have a diameter of about 1 mm or less; the smaller the droplets are, the broader the supernumerary bands become, and the less saturated their colours. Due to their origin in small droplets, supernumerary bands tend to be particularly prominent in fogbows.


title: Rainbow

text: Supernumerary rainbows cannot be explained using classical geometric optics. The alternating faint bands are caused by interference between rays of light following slightly different paths with slightly varying lengths within the raindrops. Some rays are in phase, reinforcing each other through constructive interference, creating a bright band; others are out of phase by up to half a wavelength, cancelling each other out through destructive interference, and creating a gap. Given the different angles of refraction for rays of different colours, the patterns of interference are slightly different for rays of different colours, so each bright band is differentiated in colour, creating a miniature rainbow. Supernumerary rainbows are clearest when raindrops are small and of uniform size. The very existence of supernumerary rainbows was historically a first indication of the wave nature of light, and the first explanation was provided by Thomas Young in 1804.


title: Rainbow

text: When a rainbow appears above a body of water, two complementary mirror bows may be seen below and above the horizon, originating from different light paths. Their names are slightly different.


title: Rainbow

text: A reflected rainbow may appear in the water surface below the horizon. The sunlight is first deflected by the raindrops, and then reflected off the body of water, before reaching the observer. The reflected rainbow is frequently visible, at least partially, even in small puddles.


title: Rainbow

text: A reflection rainbow may be produced where sunlight reflects off a body of water before reaching the raindrops, if the water body is large, quiet over its entire surface, and close to the rain curtain. The reflection rainbow appears above the horizon. It intersects the normal rainbow at the horizon, and its arc reaches higher in the sky, with its centre as high above the horizon as the normal rainbow's centre is below it. Reflection bows are usually brightest when the sun is low because at that time its light is most strongly reflected from water surfaces. As the sun gets lower the normal and reflection bows are drawn closer together. Due to the combination of requirements, a reflection rainbow is rarely visible.


title: Rainbow

text: Up to eight separate bows may be distinguished if the reflected and reflection rainbows happen to occur simultaneously: The normal (non-reflection) primary and secondary bows above the horizon (1, 2) with their reflected counterparts below it (3, 4), and the reflection primary and secondary bows above the horizon (5, 6) with their reflected counterparts below it (7, 8).


title: Rainbow

text: Occasionally a shower may happen at sunrise or sunset, where the shorter wavelengths like blue and green have been scattered and essentially removed from the spectrum. Further scattering may occur due to the rain, and the result can be the rare and dramatic monochrome or red rainbow.


title: Rainbow

text: In addition to the common primary and secondary rainbows, it is also possible for rainbows of higher orders to form. The order of a rainbow is determined by the number of light reflections inside the water droplets that create it: One reflection results in the first-order or "primary" rainbow; two reflections create the second-order or "secondary" rainbow. More internal reflections cause bows of higher orders—theoretically unto infinity. As more and more light is lost with each internal reflection, however, each subsequent bow becomes progressively dimmer and therefore increasingly difficult to spot. An additional challenge in observing the third-order (or "tertiary") and fourth-order ("quaternary") rainbows is their location in the direction of the sun (about 40° and 45° from the sun, respectively), causing them to become drowned in its glare.


title: Rainbow

text: For these reasons, naturally occurring rainbows of an order higher than 2 are rarely visible to the naked eye. Nevertheless, sightings of the third-order bow in nature have been reported, and in 2011 it was photographed definitively for the first time. Shortly after, the fourth-order rainbow was photographed as well, and in 2014 the first ever pictures of the fifth-order (or "quinary") rainbow were published. The quinary rainbow lies partially in the gap between the primary and secondary rainbows and is far fainter than even the secondary. In a laboratory setting, it is possible to create bows of much higher orders. Felix Billet (1808–1882) depicted angular positions up to the 19th-order rainbow, a pattern he called a "rose of rainbows". In the laboratory, it is possible to observe higher-order rainbows by using extremely bright and well collimated light produced by lasers. Up to the 200th-order rainbow was reported by Ng et al. in 1998 using a similar method but an argon ion laser beam.


title: Rainbow

text: Tertiary and quaternary rainbows should not be confused with "triple" and "quadruple" rainbows—terms sometimes erroneously used to refer to the—much more common—supernumerary bows and reflection rainbows.


title: Rainbow

text: Like most atmospheric optical phenomena, rainbows can be caused by light from the Sun, but also from the Moon. In case of the latter, the rainbow is referred to as a lunar rainbow or moonbow. They are much dimmer and rarer than solar rainbows, requiring the Moon to be near-full in order for them to be seen. For the same reason, moonbows are often perceived as white and may be thought of as monochrome. The full spectrum is present, however, but the human eye is not normally sensitive enough to see the colours. Long exposure photographs will sometimes show the colour in this type of rainbow.


title: Rainbow

text: Fogbows form in the same way as rainbows, but they are formed by much smaller cloud and fog droplets that diffract light extensively. They are almost white with faint reds on the outside and blues inside; often one or more broad supernumerary bands can be discerned inside the inner edge. The colours are dim because the bow in each colour is very broad and the colours overlap. Fogbows are commonly seen over water when air in contact with the cooler water is chilled, but they can be found anywhere if the fog is thin enough for the sun to shine through and the sun is fairly bright. They are very large—almost as big as a rainbow and much broader. They sometimes appear with a glory at the bow's centre.


title: Rainbow

text: Fog bows should not be confused with ice halos, which are very common around the world and visible much more often than rainbows (of any order), yet are unrelated to rainbows.


title: Rainbow

text: A sleetbow forms in the same way as a typical rainbow, with the exception that it occurs when light passes through falling sleet (ice pellets) instead of liquid water. As light passes through the sleet, the light is refracted causing the rare phenomena. These have been documented across United States with the earliest publicly documented and photographed sleetbow being seen in Richmond, Virginia on December 21, 2012. Just like regular rainbows, these can also come in various forms, with a monochrome sleetbow being documented on January 7, 2016 in Valparaiso, Indiana.


title: Rainbow

text: The circumzenithal and circumhorizontal arcs are two related optical phenomena similar in appearance to a rainbow, but unlike the latter, their origin lies in light refraction through hexagonal ice crystals rather than liquid water droplets. This means that they are not rainbows, but members of the large family of halos.


title: Rainbow

text: Both arcs are brightly coloured ring segments centred on the zenith, but in different positions in the sky: The circumzenithal arc is notably curved and located high above the Sun (or Moon) with its convex side pointing downwards (creating the impression of an "upside down rainbow"); the circumhorizontal arc runs much closer to the horizon, is more straight and located at a significant distance below the Sun (or Moon). Both arcs have their red side pointing towards the Sun and their violet part away from it, meaning the circumzenithal arc is red on the bottom, while the circumhorizontal arc is red on top.


title: Rainbow

text: The circumhorizontal arc is sometimes referred to by the misnomer "fire rainbow". In order to view it, the Sun or Moon must be at least 58° above the horizon, making it a rare occurrence at higher latitudes. The circumzenithal arc, visible only at a solar or lunar elevation of less than 32°, is much more common, but often missed since it occurs almost directly overhead.


title: Rainbow

text: It has been suggested that rainbows might exist on Saturn's moon Titan, as it has a wet surface and humid clouds. The radius of a Titan rainbow would be about 49° instead of 42°, because the fluid in that cold environment is methane instead of water. Although visible rainbows may be rare due to Titan's hazy skies, infrared rainbows may be more common, but an observer would need infrared night vision goggles to see them.


title: Rainbow

text: Droplets (or spheres) composed of materials with different refractive indices than plain water produce rainbows with different radius angles. Since salt water has a higher refractive index, a sea spray bow doesn't perfectly align with the ordinary rainbow, if seen at the same spot. Tiny plastic or glass marbles may be used in road marking as a reflectors to enhance its visibility by drivers at night. Due to a much higher refractive index, rainbows observed on such marbles have a noticeably smaller radius. One can easily reproduce such phenomena by sprinkling liquids of different refractive indices in the air, as illustrated in the photo.


title: Rainbow

text: The displacement of the rainbow due to different refractive indices can be pushed to a peculiar limit. For a material with a refractive index larger than 2, there is no angle fulfilling the requirements for the first order rainbow. For example, the index of refraction of diamond is about 2.4, so diamond spheres would produce rainbows starting from the second order, omitting the first order. In general, as the refractive index exceeds a number , where is a natural number, the critical incidence angle for times internally reflected rays escapes the domain formula_2. This results in a rainbow of the -th order shrinking to the antisolar point and vanishing.


title: Rainbow

text: The classical Greek scholar Aristotle (384–322 BC) was first to devote serious attention to the rainbow. According to Raymond L. Lee and Alistair B. Fraser, "Despite its many flaws and its appeal to Pythagorean numerology, Aristotle's qualitative explanation showed an inventiveness and relative consistency that was unmatched for centuries. After Aristotle's death, much rainbow theory consisted of reaction to his work, although not all of this was uncritical."


title: Rainbow

text: In Book I of "Naturales Quaestiones" (c. 65 AD), the Roman philosopher Seneca the Younger discusses various theories of the formation of rainbows extensively, including those of Aristotle. He notices that rainbows appear always opposite to the Sun, that they appear in water sprayed by a rower, in the water spat by a fuller on clothes stretched on pegs or by water sprayed through a small hole in a burst pipe. He even speaks of rainbows produced by small rods (virgulae) of glass, anticipating Newton's experiences with prisms. He takes into account two theories: one, that the rainbow is produced by the Sun reflecting in each water drop, the other, that it is produced by the Sun reflected in a cloud shaped like a concave mirror; he favours the latter. He also discusses other phenomena related to rainbows: the mysterious "virgae" (rods), halos and parhelia.


title: Rainbow

text: According to Hüseyin Gazi Topdemir, the Arab physicist and polymath Ibn al-Haytham (Alhazen; 965–1039), attempted to provide a scientific explanation for the rainbow phenomenon. In his "Maqala fi al-Hala wa Qaws Quzah" ("On the Rainbow and Halo"), al-Haytham "explained the formation of rainbow as an image, which forms at a concave mirror. If the rays of light coming from a farther light source reflect to any point on axis of the concave mirror, they form concentric circles in that point. When it is supposed that the sun as a farther light source, the eye of viewer as a point on the axis of mirror and a cloud as a reflecting surface, then it can be observed the concentric circles are forming on the axis." He was not able to verify this because his theory that "light from the sun is reflected by a cloud before reaching the eye" did not allow for a possible experimental verification. This explanation was repeated by Averroes, and, though incorrect, provided the groundwork for the correct explanations later given by Kamāl al-Dīn al-Fārisī in 1309 and, independently, by Theodoric of Freiberg (c. 1250–c. 1311)—both having studied al-Haytham's "Book of Optics".


title: Rainbow

text: Ibn al-Haytham's contemporary, the Persian philosopher and polymath Ibn Sīnā (Avicenna; 980–1037), provided an alternative explanation, writing "that the bow is not formed in the dark cloud but rather in the very thin mist lying between the cloud and the sun or observer. The cloud, he thought, serves simply as the background of this thin substance, much as a quicksilver lining is placed upon the rear surface of the glass in a mirror. Ibn Sīnā would change the place not only of the bow, but also of the colour formation, holding the iridescence to be merely a subjective sensation in the eye." This explanation, however, was also incorrect. Ibn Sīnā's account accepts many of Aristotle's arguments on the rainbow.


title: Rainbow

text: In Song Dynasty China (960–1279), a polymath scholar-official named Shen Kuo (1031–1095) hypothesised—as a certain Sun Sikong (1015–1076) did before him—that rainbows were formed by a phenomenon of sunlight encountering droplets of rain in the air. Paul Dong writes that Shen's explanation of the rainbow as a phenomenon of atmospheric refraction "is basically in accord with modern scientific principles."


title: Rainbow

text: According to Nader El-Bizri, the Persian astronomer, Qutb al-Din al-Shirazi (1236–1311), gave a fairly accurate explanation for the rainbow phenomenon. This was elaborated on by his student, Kamāl al-Dīn al-Fārisī (1267–1319), who gave a more mathematically satisfactory explanation of the rainbow. He "proposed a model where the ray of light from the sun was refracted twice by a water droplet, one or more reflections occurring between the two refractions." An experiment with a water-filled glass sphere was conducted and al-Farisi showed the additional refractions due to the glass could be ignored in his model. As he noted in his "Kitab Tanqih al-Manazir" ("The Revision of the Optics"), al-Farisi used a large clear vessel of glass in the shape of a sphere, which was filled with water, in order to have an experimental large-scale model of a rain drop. He then placed this model within a camera obscura that has a controlled aperture for the introduction of light. He projected light unto the sphere and ultimately deduced through several trials and detailed observations of reflections and refractions of light that the colours of the rainbow are phenomena of the decomposition of light.


title: Rainbow

text: In Europe, Ibn al-Haytham's "Book of Optics" was translated into Latin and studied by Robert Grosseteste. His work on light was continued by Roger Bacon, who wrote in his "Opus Majus" of 1268 about experiments with light shining through crystals and water droplets showing the colours of the rainbow. In addition, Bacon was the first to calculate the angular size of the rainbow. He stated that the rainbow summit can not appear higher than 42° above the horizon. Theodoric of Freiberg is known to have given an accurate theoretical explanation of both the primary and secondary rainbows in 1307. He explained the primary rainbow, noting that "when sunlight falls on individual drops of moisture, the rays undergo two refractions (upon ingress and egress) and one reflection (at the back of the drop) before transmission into the eye of the observer." He explained the secondary rainbow through a similar analysis involving two refractions and two reflections.


title: Rainbow

text: Descartes' 1637 treatise, "Discourse on Method," further advanced this explanation. Knowing that the size of raindrops did not appear to affect the observed rainbow, he experimented with passing rays of light through a large glass sphere filled with water. By measuring the angles that the rays emerged, he concluded that the primary bow was caused by a single internal reflection inside the raindrop and that a secondary bow could be caused by two internal reflections. He supported this conclusion with a derivation of the law of refraction (subsequently to, but independently of, Snell) and correctly calculated the angles for both bows. His explanation of the colours, however, was based on a mechanical version of the traditional theory that colours were produced by a modification of white light.


title: Rainbow

text: Isaac Newton demonstrated that white light was composed of the light of all the colours of the rainbow, which a glass prism could separate into the full spectrum of colours, rejecting the theory that the colours were produced by a modification of white light. He also showed that red light is refracted less than blue light, which led to the first scientific explanation of the major features of the rainbow. Newton's corpuscular theory of light was unable to explain supernumerary rainbows, and a satisfactory explanation was not found until Thomas Young realised that light behaves as a wave under certain conditions, and can interfere with itself.


title: Rainbow

text: Young's work was refined in the 1820s by George Biddell Airy, who explained the dependence of the strength of the colours of the rainbow on the size of the water droplets. Modern physical descriptions of the rainbow are based on Mie scattering, work published by Gustav Mie in 1908. Advances in computational methods and optical theory continue to lead to a fuller understanding of rainbows. For example, Nussenzveig provides a modern overview.


title: Rainbow

text: Experiments on the rainbow phenomenon using artificial raindrops, i.e. water-filled spherical flasks, go back at least to Theodoric of Freiberg in the 14th century. Later, also Descartes studied the phenomenon using a Florence flask. A flask experiment known as Florence's rainbow is still often used today as an imposing and intuitively accessible demonstration experiment of the rainbow phenomenon. It consists in illuminating (with parallel white light) a water-filled spherical flask through a hole in a screen. A rainbow will then appear thrown back / projected on the screen, provided the screen is large enough. Due to the finite wall thickness and the macroscopic character of the artificial raindrop, several subtle differences exist as compared to the natural phenomenon, including slightly changed rainbow angles and a splitting of the rainbow orders.


title: Rainbow

text: A very similar experiment consists in using a cylindrical glass vessel filled with water or a solid transparent cylinder and illuminated either parallel to the circular base (i.e. light rays remaining at a fixed height while they transit the cylinder) or under an angle to the base. Under these latter conditions the rainbow angles change relative to the natural phenomenon since the effective index of refraction of water changes (Bravais' index of refraction for inclined rays applies).


title: Rainbow

text: Rainbows occur frequently in mythology, and have been used in the arts. The first literary occurrence of a rainbow is in the Book of Genesis chapter 9, as part of the flood story of Noah, where it is a sign of God's covenant to never destroy all life on Earth with a global flood again. In Norse mythology, the rainbow bridge Bifröst connects the world of men (Midgard) and the realm of the gods (Asgard). Cuchavira was the god of the rainbow for the Muisca in present-day Colombia and when the regular rains on the Bogotá savanna were over, the people thanked him offering gold, snails and small emeralds. Some forms of Tibetan Buddhism or Dzogchen reference a rainbow body. The Irish leprechaun's secret hiding place for his pot of gold is usually said to be at the end of the rainbow. This place is appropriately impossible to reach, because the rainbow is an optical effect which cannot be approached. In Greek mythology, the goddess Iris is the personification of the rainbow, a messenger goddess who, like the rainbow, connects the mortal world with the gods through messages.


title: Rainbow

text: Rainbows appear in heraldry - in heraldry the rainbow proper consists of 4 bands of colour (Or, Gules, Vert, Argent) with the ends resting on clouds. Generalised examples in coat of arms include those of the towns of Regen and Pfreimd, both in Bavaria, Germany; of Bouffémont, France; and of the 69th Infantry Regiment (New York) of the United States Army National Guard.


title: Rainbow

text: Rainbow flags have been used for centuries. It was a symbol of the Cooperative movement in the German Peasants' War in the 16th century, of peace in Italy, and of gay pride and LGBT social movements since the 1970s. In 1994, Archbishop Desmond Tutu and President Nelson Mandela described newly democratic post-apartheid South Africa as the rainbow nation. The rainbow has also been used in technology product logos, including the Apple computer logo. Many political alliances spanning multiple political parties have called themselves a "Rainbow Coalition".

text: In Saudi Arabia (and some other countries), authorities seize rainbow-coloured children's clothing and toys (such as hats, hair clips, and pencil cases, not just flags), which they claim encourage homosexuality, and selling such is illegal.


title: Sciatica

text: Sciatica is pain going down the leg from the lower back. This pain may go down the back, outside, or front of the leg. Onset is often sudden following activities like heavy lifting, though gradual onset may also occur. The pain is often described as shooting. Typically, symptoms are only on one side of the body. Certain causes, however, may result in pain on both sides. Lower back pain is sometimes present. Weakness or numbness may occur in various parts of the affected leg and foot.


title: Sciatica

text: About 90% of sciatica is due to a spinal disc herniation pressing on one of the lumbar or sacral nerve roots. Spondylolisthesis, spinal stenosis, piriformis syndrome, pelvic tumors, and pregnancy are other possible causes of sciatica. The straight-leg-raising test is often helpful in diagnosis. The test is positive if, when the leg is raised while a person is lying on their back, pain shoots below the knee. In most cases medical imaging is not needed. However, imaging may be obtained if bowel or bladder function is affected, there is significant loss of feeling or weakness, symptoms are long standing, or there is a concern for tumor or infection. Conditions that may present similarly are diseases of the hip and infections such as early shingles (prior to rash formation).


title: Sciatica

text: Initial treatment typically involves pain medications. However, evidence for pain medication and muscle relaxants is lacking. It is generally recommended that people continue with normal activity to the best of their abilities. Often all that is required for sciatica resolution is time; in about 90% of people symptoms resolve in less than six weeks. If the pain is severe and lasts for more than six weeks, surgery may be an option. While surgery often speeds pain improvement, its long term benefits are unclear. Surgery may be required if complications occur, such as loss of normal bowel or bladder function. Many treatments, including corticosteroids, gabapentin, pregabalin, acupuncture, heat or ice, and spinal manipulation, have limited or poor evidence for their use.


title: Sciatica

text: Depending on how it is defined, less than 1% to 40% of people have sciatica at some point in time. Sciatica is most common between the ages of 40 and 59, and men are more frequently affected than women. The condition has been known since ancient times. The first known use of the word "sciatica" dates from 1451.


title: Sciatica

text: The term "sciatica" usually describes a symptom—pain along the sciatic nerve pathway—rather than a specific condition, illness, or disease. Some use it to mean any pain starting in the lower back and going down the leg. The pain is characteristically described as shooting or shock-like, quickly traveling along the course of the affected nerves. Others use the term as a diagnosis (i.e. an indication of cause and effect) for nerve dysfunction caused by compression of one or more lumbar or sacral nerve roots from a spinal disc herniation. Pain typically occurs in the distribution of a dermatome and goes below the knee to the foot. It may be associated with neurological dysfunction, such as weakness and numbness.


title: Sciatica

text: Modifiable risk factors for sciatica include smoking, obesity, occupation, and physical sports where back muscles and heavy weights are involved. Non-modifiable risk factors include increasing age, being male, and having a personal history of low back pain.


title: Sciatica

text: Spinal disc herniation pressing on one of the lumbar or sacral nerve roots is the most frequent cause of sciatica, being present in about 90% of cases. This is particularly true in those under age 50. Disc herniation most often occurs during heavy lifting. Pain typically increases when bending forward or sitting, and reduces when lying down or walking.


title: Sciatica

text: Other compressive spinal causes include lumbar spinal stenosis, a condition in which the spinal canal, the space the spinal cord runs through, narrows and compresses the spinal cord, cauda equina, or sciatic nerve roots. This narrowing can be caused by bone spurs, spondylolisthesis, inflammation, or a herniated disc, which decreases available space for the spinal cord, thus pinching and irritating nerves from the spinal cord that become the sciatic nerve. This is the most frequent cause after age 50. Sciatic pain due to spinal stenosis is most commonly brought on by standing, walking, or sitting for extended periods of time, and reduces when bending forward. However, pain can arise with any position or activity in severe cases. The pain is most commonly relieved by rest.


title: Sciatica

text: Piriformis syndrome is a condition that, depending on the analysis, varies from a "very rare" cause to contributing up to 8% of low back or buttock pain. In 17% of people, the sciatic nerve runs through the piriformis muscle rather than beneath it. When the piriformis shortens or spasms due to trauma or overuse, it is posited that this causes compression of the sciatic nerve. Piriformis syndrome has colloquially been referred to as "wallet sciatica" since a wallet carried in a rear hip pocket compresses the buttock muscles and sciatic nerve when the bearer sits down. Piriformis syndrome may be suspected as a cause of sciatica when the spinal nerve roots contributing to the sciatic nerve are normal and no herniation of a spinal disc is apparent.


title: Sciatica

text: Sciatic endometriosis, also called catamenial or cyclical sciatica, is a sciatica whose cause is endometriosis. Its incidence is unknown. Diagnosis is usually made by an MRI or CT-myelography.


title: Sciatica

text: Sciatica may also occur during pregnancy, especially during later stages, as a result of the weight of the fetus pressing on the sciatic nerve during sitting or during leg spasms. While most cases do not directly harm the woman or the fetus, indirect harm may come from the numbing effect on the legs, which can cause loss of balance and falls. There is no standard treatment for pregnancy-induced sciatica.


title: Sciatica

text: Pain that does not improve when lying down suggests a nonmechanical cause, such as cancer, inflammation, or infection. Sciatica can be caused by tumors impinging on the spinal cord or the nerve roots. Severe back pain extending to the hips and feet, loss of bladder or bowel control, or muscle weakness may result from spinal tumors or cauda equina syndrome. Trauma to the spine, such as from a car accident or hard fall onto the heel or buttocks, may also lead to sciatica. A relationship has been proposed with a latent "Cutibacterium acnes" infection in the intervertebral discs, but the role it plays is not yet clear.


title: Sciatica

text: Sciatica is generally caused by the compression of lumbar nerves L4 or L5 or sacral nerve S1. Less commonly, sacral nerves S2 or S3 or compression of the sciatic nerve itself may cause sciatica. In 90% of sciatica cases, this can occur as a result of a spinal disc bulge or herniation. Intervertebral spinal discs consist of an outer anulus fibrosus and an inner nucleus pulposus. The anulus fibrosus forms a rigid ring around the nucleus pulposus early in human development, and the gelatinous contents of the nucleus pulposus are thus contained within the disc. Discs separate the spinal vertebrae, thereby increasing spinal stability and allowing nerve roots to properly exit through the spaces between the vertebrae from the spinal cord. As an individual ages, the anulus fibrosus weakens and becomes less rigid, making it at greater risk for tear. When there is a tear in the anulus fibrosus, the nucleus pulposus may extrude through the tear and press against spinal nerves within the spinal cord, cauda equina, or exiting nerve roots, causing inflammation, numbness, or excruciating pain. Inflammation of spinal tissue can then spread to adjacent facet joints and cause facet syndrome, which is characterized by lower back pain and referred pain in the posterior thigh.


title: Sciatica

text: Other causes of sciatica secondary to spinal nerve entrapment include the roughening, enlarging, or misalignment ("spondylolisthesis") of vertebrae, or disc degeneration that reduces the diameter of the lateral foramen through which nerve roots exit the spine. When sciatica is caused by compression of a dorsal nerve root, it is considered a lumbar radiculopathy or radiculitis when accompanied by an inflammatory response. Sciatica-like pain prominently focused in the buttocks can also be caused by compression of peripheral sections of the sciatic nerve usually from soft tissue tension in the piriformis or related muscles.


title: Sciatica

text: Generally, if a person reports the typical radiating pain in one leg, as well as one or more neurological indications of nerve root tension or neurological deficit, sciatica can be diagnosed.


title: Sciatica

text: The most frequently used diagnostic test is the straight leg raise to produce Lasègue's sign, which is considered positive if pain in the distribution of the sciatic nerve is reproduced with passive flexion of the straight leg between 30 and 70 degrees. While this test is positive in about 90% of people with sciatica, approximately 75% of people with a positive test do not have sciatica. Straight leg raising of the leg unaffected by sciatica may produce sciatica in the leg on the affected side; this is known as the Fajersztajn sign. The presence of the Fajersztajn sign is a more specific finding for a herniated disc than Lasègue's sign. Maneuvers that increase intraspinal pressure, such as coughing, flexion of the neck, and bilateral compression of the jugular veins, may transiently worsen sciatica pain.


title: Sciatica

text: Imaging modalities such as computerised tomography or magnetic resonance imaging can help with the diagnosis of lumbar disc herniation. The utility of MR neurography in the diagnosis of piriformis syndrome is controversial.


title: Sciatica

text: Discography could be considered to determine a specific disc's role in an individual's pain. Discography involves the insertion of a needle into a disc to determine the pressure of disc space. Radiocontrast is then injected into the disc space to assess for visual changes that may indicate an anatomic abnormality of the disc. The reproduction of an individual's pain during discography is also diagnostic.


title: Sciatica

text: Cancer should be suspected if there is previous history of it, unexplained weight loss, or unremitting pain. Spinal epidural abscess is more common among those who have diabetes mellitus or immunodeficiency, or who have had spinal surgery, injection or catheter; it typically causes fever, leukocytosis and increased erythrocyte sedimentation rate. If cancer or spinal epidural abscess is suspected, urgent magnetic resonance imaging is recommended for confirmation. Proximal diabetic neuropathy typically affects middle aged and older people with well-controlled type-2 diabetes mellitus; onset is sudden, causing pain, usually in multiple dermatomes, quickly followed by weakness. Diagnosis typically involves electromyography and lumbar puncture. Shingles is more common among the elderly and immunocompromised; typically, pain is followed by the appearance of a rash with small blisters along a single dermatome. Acute Lyme radiculopathy may follow a history of outdoor activities during warmer months in likely tick habitats in the previous 1–12 weeks. In the U.S., Lyme is most common in New England and Mid-Atlantic states and parts of Wisconsin and Minnesota, but it is expanding to other areas. The first manifestation is usually an expanding rash possibly accompanied by flu-like symptoms. Lyme can also cause a milder, chronic radiculopathy an average of 8 months after the acute illness.


title: Sciatica

text: Sciatica can be managed with a number of different treatments with the goal of restoring a person's normal functional status and quality of life. When the cause of sciatica is lumbar disc herniation (90% of cases), most cases resolve spontaneously over weeks to months. Initially treatment in the first 6–8 weeks should be conservative. More than 75% of sciatica cases are managed without surgery. In persons that smoke who also have sciatica, smoking cessation should be strongly considered, in order to promote healing. Treatment of the underlying cause of nerve compression is needed in cases of epidural abscess, epidural tumors, and cauda equina syndrome.


title: Sciatica

text: Physical activity is often recommended for the conservative management of sciatica for persons who are physically able. However, the difference in outcomes between physical activity compared to bed rest have not been fully elucidated. The evidence for physical therapy in sciatica is unclear though such programs appear safe. Physical therapy is commonly used. Nerve mobilization techniques for sciatic nerve is supported by tentative evidence.


title: Sciatica

text: There is no one medication regimen used to treat sciatica. Evidence supporting the use of opioids and muscle relaxants is poor. Low-quality evidence indicates that NSAIDs do not appear to improve immediate pain, and all NSAIDs appear to be nearly equivalent in their ability to relieve sciatica. Nevertheless, NSAIDs are commonly recommended as a first-line treatment for sciatica. In those with sciatica due to piriformis syndrome, botulinum toxin injections may improve pain and function. While there is little evidence supporting the use of epidural or systemic steroids, systemic steroids may be offered to individuals with confirmed disc herniation if there is a contraindication to NSAID use. Low-quality evidence supports the use of gabapentin for acute pain relief in those with chronic sciatica. Anticonvulsants and biologics have not been shown to improve acute or chronic sciatica. Antidepressants have demonstrated some efficacy in treating chronic sciatica, and may be offered to individuals who are not amenable to NSAIDs or who have failed NSAID therapy.


title: Sciatica

text: If sciatica is caused by a herniated disc, the disc's partial or complete removal, known as a discectomy, has tentative evidence of benefit in the short term. If the cause is spondylolisthesis or spinal stenosis, surgery appears to provide pain relief for up to two years.


title: Sciatica

text: Low to moderate-quality evidence suggests that spinal manipulation is an effective treatment for acute sciatica. For chronic sciatica, the evidence supporting spinal manipulation as treatment is poor. Spinal manipulation has been found generally safe for the treatment of disc-related pain; however, case reports have found an association with cauda equina syndrome, and it is contraindicated when there are progressive neurological deficits.


title: Sciatica

text: About 39% to 50% of people with sciatica still have symptoms after one to four years. In one study, around 20% were unable to work at their one-year followup, and 10% had had surgery for the condition.


title: Sciatica

text: Depending on how it is defined, less than 1% to 40% of people have sciatica at some point in time. Sciatica is most common between the ages of 40 and 59, and men are more frequently affected than women.


title: The Hunt for Red October (film)

text: The Hunt for Red October is a 1990 American submarine spy thriller film directed by John McTiernan, produced by Mace Neufeld, and starring Sean Connery, Alec Baldwin, Scott Glenn, James Earl Jones, and Sam Neill. The film is an adaptation of Tom Clancy's 1984 bestselling novel of the same name. It is the first installment of the film series with the protagonist Jack Ryan.


title: The Hunt for Red October (film)

text: The story is set during the late Cold War era and involves a rogue Soviet naval captain who wishes to defect to the United States with his officers and the Soviet Navy's newest and most advanced ballistic missile submarine, a fictional improvement on the Soviet Typhoon-class submarine. A CIA analyst correctly deduces his motive and must prove his theory to the U.S. Navy before a violent confrontation between the Soviet and the American navies spirals out of control.


title: The Hunt for Red October (film)

text: The film was a co-production between the motion picture studios Paramount Pictures, Mace Neufeld Productions, and Nina Saxon Film Design. Theatrically, it was commercially distributed by Paramount Pictures and by the Paramount Home Entertainment division for home media markets. Following its wide theatrical release, the film was nominated for and won a number of accolades. At the 63rd Academy Awards, the film was honored with the Academy Award for Best Sound Editing, along with nominations for Best Sound Mixing and Best Film Editing. On June 12, 1990, the original soundtrack, composed and conducted by Basil Poledouris, was released by MCA Records. "The Hunt for Red October" received mostly positive reviews from critics and was the sixth-highest-grossing domestic film of the year, generating $122 million in North America and more than $200 million worldwide in box office business.


title: The Hunt for Red October (film)

text: In November 1984, Soviet submarine captain Marko Ramius is given command of , a new Typhoon-class ballistic missile submarine with a "caterpillar drive", rendering it undetectable to passive sonar. Ramius leaves port to conduct exercises along with Alfa-class attack submarine "V. K. Konovalov", commanded by his former student Captain Tupolev. At sea, Ramius secretly kills political officer Ivan Putin and relays false orders to his crew that they are to conduct missile drills off America's east coast. American attack submarine USS "Dallas", which had been shadowing "Red October", loses contact once the sub's caterpillar drive is engaged.


title: The Hunt for Red October (film)

text: CIA analyst and former Marine Jack Ryan, after consulting with Vice Admiral James Greer, the Deputy Director of the CIA, briefs government officials on "Red October" and the threat it poses. After learning that the bulk of the Soviet Navy has been deployed to the Atlantic to find and sink the sub, they conclude that Ramius plans a renegade nuclear strike. During the briefing, Ryan hypothesizes that Ramius, a native-born Lithuanian widower with few remaining personal ties to the Soviet Union, instead plans to defect to the United States, and National Security Advisor Jeffrey Pelt gives Ryan three days to confirm his theory. He is sent to an aircraft carrier in the mid-Atlantic. Meanwhile, after some delay, Tupolev also receives orders to intercept and destroy "Red October".


title: The Hunt for Red October (film)

text: Due to an unknown saboteur's actions, "Red October"s caterpillar drive malfunctions during risky maneuvers through a narrow undersea canyon. Petty Officer Jones, a sonar technician aboard "Dallas", discovers a way to detect "Red October" using his underwater acoustics software, and "Dallas" plots an intercept course. After a hazardous mid-ocean transfer, Ryan is able to board "Dallas", where he attempts to persuade its captain, Commander Bart Mancuso, to contact Ramius and determine his real intentions.


title: The Hunt for Red October (film)

text: The Soviet ambassador informs the U.S. government that Ramius is a renegade and asks for help in sinking "Red October". That order is sent to the U.S. fleet, including "Dallas", which has reacquired the Soviet sub. Ryan remains convinced that Ramius plans to defect with his officers and finally convinces Mancuso to contact Ramius and offer assistance. Ramius, stunned that the Americans correctly guessed his plan, accepts Mancuso's offer. He then stages a nuclear reactor "emergency", ordering the sub to surface and his crew to abandon ship. After a U.S. frigate is spotted heading right for them, Ramius submerges, leaving his crew in life rafts. Ryan, Mancuso, and Jones board "Red October" via a rescue sub. Docking with "Red October", they meet Ramius who requests asylum for himself and his officers.


title: The Hunt for Red October (film)

text: "Red October" is suddenly ambushed by "Konovalov". As the two Soviet subs maneuver, one of "Red October"s cooks, Loginov, is revealed to be an undercover GRU agent and the saboteur. He opens fire on the bridge, fatally wounding first officer Vasily Borodin, before retreating to the missile bay, intending to ignite a missile engine and destroy the ship. Loginov is pursued by Ryan and Ramius, and he wounds Ramius before being killed by Ryan. Meanwhile, "Konovalov" fires upon "Red October" with a torpedo, which "Dallas" is able to divert toward herself and evade by launching countermeasures and conducting an emergency blow to the surface. The torpedo reacquires "Red October" but Mancuso, placed in temporary command by Ramius, executes a maneuver that diverts the torpedo towards "Konovalov", which it strikes and destroys. The crew of "Red October", now rescued, witness the explosion from the deck of the U.S. frigate. Unaware of the second Soviet submarine, they believe that Ramius has sacrificed himself and scuttled "Red October" to avoid being boarded.


title: The Hunt for Red October (film)

text: Ryan and Ramius, their subterfuge complete, navigate "Red October" to the Penobscot River in Maine. Ramius admits that he defected because he believed "Red October" was intended for a preemptive nuclear first strike against the United States and was unwilling to support such an action. Ryan boards a flight home to London and, thanks to his exertions, is finally able to sleep aboard a plane while seated next to a teddy bear intended for his daughter.


title: The Hunt for Red October (film)

text: In addition, the director's father, John McTiernan Sr., has a credited cameo as one of the attendees at Ryan's briefing of the National Security Advisor.


title: The Hunt for Red October (film)

text: Producer Mace Neufeld optioned Tom Clancy's novel after reading galley proofs in February 1985. Despite the book becoming a best seller, no Hollywood studio was interested because of its content. Neufeld said, "I read some of the reports from the other studios, and the story was too complicated to understand". After a year and a half he finally got a high-level executive at Paramount Pictures to read Clancy's novel and agree to develop it into a film.


title: The Hunt for Red October (film)

text: Screenwriters Larry Ferguson and Donald Stewart worked on the screenplay while Neufeld approached the U.S. Navy for approval. They feared top secret information or technology might be revealed. However, several admirals liked Clancy's book and reasoned that the film could do for submariners what "Top Gun" did for the Navy's jet fighter pilots. Captain Michael Sherman, director of the Navy's western regional information office in Los Angeles, suggested changes to the script that would present the Navy in a positive light.


title: The Hunt for Red October (film)

text: The Navy gave the filmmakers access to several s, allowing them to photograph unclassified sections of both and to use in set and prop design. was used for the scene in which Baldwin is dropped from a helicopter to the submarine. Key cast and crew members rode along in subs, including Alec Baldwin and Scott Glenn, who took an overnight trip aboard commanded by then Commander Thomas B. Fargo. Glenn based his portrayal of Commander Bart Mancuso on Fargo.


title: The Hunt for Red October (film)

text: The film is a somewhat faithful adaptation of Clancy's novel, though there are many deviations, including "Red October" traveling up the Penobscot River in Maine to dry dock, the omission of the Royal Navy task force including Ryan's time aboard , the death of Borodin rather than Kamarov, and "V. K. Konovalov" being serendipitously destroyed by its own torpedo as opposed to being rammed by "Red October", with the planned explosion of USS "Ethan Allen" as a subterfuge.


title: The Hunt for Red October (film)

text: Some of the principal cast had previous military service which they drew on for their roles. Sean Connery had served in the Royal Navy, Scott Glenn in the United States Marine Corps, and James Earl Jones in the United States Army. Baldwin and Glenn spent time on a "Los Angeles"-class submarine. Baldwin was trained to drive an attack submarine. Some extras portraying the "Dallas" crew were serving submariners, including the pilot of the DSRV, Lt Cmdr George Billy. Submariners from San Diego were cast as extras because it was easier to hire them than to train actors. Crew from , including Lt Mark Draxton, took leave to participate in filming. According to an article in "Sea Classics", at least two sailors from the Atlantic Fleet-based "Dallas" took leave and participated in the Pacific Fleet-supported filming. The crew of "Houston" called their month-long filming schedule the "Hunt for Red Ops." "Houston" made more than 40 emergency surfacing "blows" for rehearsal and for the cameras.


title: The Hunt for Red October (film)

text: The filmmakers' first choice to portray Jack Ryan was Kevin Costner, who turned down the film in order to star in and direct "Dances with Wolves". Harrison Ford was also approached to play Jack Ryan but turned it down; he would later replace Alec Baldwin as Ryan in "Patriot Games". Baldwin was approached in December 1988, but was not told for what role. Klaus Maria Brandauer was cast as Soviet sub commander Marko Ramius but quit two weeks into filming due to a prior commitment. The producers faxed the script to Sean Connery, who at first declined because the script seemed implausible in portraying the Soviet Union as an ambitious naval power. He was missing the first page which set the story before Gorbachev's coming to power, when the events of the book would have seemed more plausible. He arrived in L.A. on a Friday and was supposed to start filming on Monday but he requested a day to rehearse. Principal photography began on April 3, 1989 with a $30 million budget. The Navy lent the film crew "Houston", , two frigates ( and ), helicopters, and a dry-dock crew.


title: The Hunt for Red October (film)

text: Filmmaker John Milius revised some of the film's script, writing a few speeches for Sean Connery and all of his Russian dialogue. He was asked to rewrite the whole film but was only required to do the Russian sequences. Rather than choosing between the realism of Russian dialog with subtitles, or the audience-friendly use of English (with or without Russian accents), the filmmakers compromised with a deliberate conceit. The film begins with the actors speaking Russian with English subtitles. But in an early scene, actor Peter Firth casually switches in mid-sentence to speaking in English on the word "Armageddon", which is the same spoken word in both languages. After that point, all the Soviets' dialogue is communicated in English. Connery continued using his native Scottish accent for the rest of the motion picture. Only towards the climax of the film, at the beginning of the scene in which the Soviet and American submariners meet, do some of the actors speak in Russian again.


title: The Hunt for Red October (film)

text: Filming in submarines was impractical. Instead, five soundstages on the Paramount backlot were used. Two platforms housing mock-ups of "Red October" and "Dallas" were built, standing on hydraulic gimbals that simulated the sub's movements. Connery recalled, "It was very claustrophobic. There were 62 people in a very confined space, above the stage floor. It got very hot on the sets, and I'm also prone to sea sickness. The set would tilt to 45 degrees. Very disturbing." The veteran actor shot for four weeks and the rest of the production shot for additional months on location in Port Angeles, Washington and the waters off Los Angeles. Scenes of a shipyard in Patuxent, Maryland were filmed at a submarine base in Point Loma, San Diego.


title: The Hunt for Red October (film)

text: Made before the extensive use of CGI became the norm in filmmaking, the film's opening sequence featured a long pull-out reveal of the immense titular Typhoon-class sub. It included a nearly full-scale, above-the-water-line mockup of the sub, constructed from two barges welded together. Each country's submarine had its own background color: Soviet submarines, such as "Red October" and "V.K. Konovalov", had interiors in black with chrome trim. American ships, such as "Dallas" and "Enterprise", had grey interiors. Early filming was aboard USS "Reuben James" in the area of the Juan de Fuca Strait and Puget Sound in March 1989. The ship operated out of U.S. Coast Guard Station Port Angeles. The SH-60B detachment from the Battlecats of HSL-43 operated out of NAS Whidbey Island, after being displaced by the film crew. Most underwater scenes were filmed using smoke with a model sub connected to 12 cables, giving precise, smooth control for turns. Computer effects, in their infancy, created bubbles and other effects such as particulates in the water.


title: The Hunt for Red October (film)

text: By March 1990, just before the film's theatrical release, the Soviet Parliament removed the Communist Party from government, effectively ending the Cold War. Set during this period, there were concerns that with its end, the film would be irrelevant but Neufeld felt that it "never really represented a major problem". To compensate for the change in the Soviet Union's political climate, an on-screen crawl appears at the beginning of the film stating that it takes place in 1984 during the Cold War. Tony Seiniger designed the film's poster and drew inspiration from Soviet poster art, using bold red, white and black graphics. According to him, the whole ad campaign was designed to have a "techno-suspense quality to it". The idea was to play up the thriller aspects and downplay the political elements.


title: The Hunt for Red October (film)

text: The film caused a minor sensation in the black projects submarine warfare technology community. In one scene, where USS "Dallas" is chasing "Red October" through the submarine canyon, the crew can be heard calling out that they have various "milligal anomalies". This essentially revealed the use of gravimetry as a method of silent navigation in US submarines (though this method of navigation had been explained as the navigation method of the "Red October" in the book six years earlier). Thought to be a billion dollar black project, the development of a full-tensor gravity gradiometer by Bell Aerospace was a classified technology at the time. It was thought to be deployed on only a few s after it was first developed in 1973. Bell Aerospace later sold the technology to Bell Geospace for oil exploration purposes. The last Typhoon-class submarine was officially laid down in 1986, under the name "TK-210", but according to sources was never finished and scrapped in 1990.


title: The Hunt for Red October (film)

text: The musical score of "The Hunt for Red October" was composed and conducted by Basil Poledouris. A soundtrack album composed of ten melodies was released on June 12, 1990. The album is missing some of the musical moments present in the film, including the scene where the crew of "Red October" sings the Soviet national hymn. The soundtrack is limited due to the fact that it was originally compiled to fit the Compact Cassette. Later, it was remastered for the CD. An expanded version was released in late 2013 by Intrada Records. It features 40 additional minutes of the score, including the until-then-unreleased end titles.

text: "The Hunt for Red October" opened in 1,225 theaters on March 2, 1990, grossing $17 million on its opening weekend, more than half its budget. The film opened at number one at the U.S. box office and remained there for three weeks. Its opening was the 20th biggest weekend of all time and the biggest non-summer, non-Thanksgiving weekend to date.

text: On Rotten Tomatoes the film holds an approval rating of 88% based on 73 reviews, with an average rating of 7.70/10. The site's consensus states: "Perfectly cast and packed with suspense, "The Hunt for Red October" is an old-fashioned submarine thriller with plenty of firepower to spare." On Metacritic, it has a weighted average score of 58 out of 100 based on 17 critics, indicating "mixed or average views". Audiences polled by CinemaScore gave the film an average grade of "A" on an A+ to F scale.

text: Roger Ebert gave the film three-and-a-half stars out of four, calling it "a skillful, efficient film that involves us in the clever and deceptive game being played", while Gene Siskel commented on the film's technical achievement and Baldwin's convincing portrayal of Jack Ryan. Nick Schager, for "Slant" magazine's review, noted, ""The Hunt for Red October" is a thrilling edge-of-your-seat trifle that has admirably withstood the test of time". In contrast, "Newsweek"s David Ansen wrote, "But it's at the gut level that "Red October" disappoints. This smoother, impressively mounted machine is curiously ungripping. Like an overfilled kettle, it takes far too long to come to a boil". Vincent Canby, writing for "The New York Times", opined that "the characters, like the lethal hardware, are simply functions of the plot, which in this case seems to be a lot more complex than it really is".

title: Ralph Waldo Emerson

text: Ralph Waldo Emerson (May 25, 1803April 27, 1882), who went by his middle name Waldo, was an American essayist, lecturer, philosopher, abolitionist, and poet who led the transcendentalist movement of the mid-19th century. He was seen as a champion of individualism and a prescient critic of the countervailing pressures of society, and his ideology was disseminated through dozens of published essays and more than 1,500 public lectures across the United States.


title: Ralph Waldo Emerson

text: Emerson gradually moved away from the religious and social beliefs of his contemporaries, formulating and expressing the philosophy of transcendentalism in his 1836 essay "Nature". Following this work, he gave a speech entitled "The American Scholar" in 1837, which Oliver Wendell Holmes Sr. considered to be America's "intellectual Declaration of Independence."


title: Ralph Waldo Emerson

text: Emerson wrote most of his important essays as lectures first and then revised them for print. His first two collections of essays, "" (1841) and "" (1844), represent the core of his thinking. They include the well-known essays "Self-Reliance", "The Over-Soul", "Circles", "The Poet", and "Experience." Together with "Nature", these essays made the decade from the mid-1830s to the mid-1840s Emerson's most fertile period. Emerson wrote on a number of subjects, never espousing fixed philosophical tenets, but developing certain ideas such as individuality, freedom, the ability for mankind to realize almost anything, and the relationship between the soul and the surrounding world. Emerson's "nature" was more philosophical than naturalistic: "Philosophically considered, the universe is composed of Nature and the Soul." Emerson is one of several figures who "took a more pantheist or pandeist approach by rejecting views of God as separate from the world."


title: Ralph Waldo Emerson

text: He remains among the linchpins of the American romantic movement, and his work has greatly influenced the thinkers, writers and poets that followed him. "In all my lectures," he wrote, "I have taught one doctrine, namely, the infinitude of the private man." Emerson is also well known as a mentor and friend of Henry David Thoreau, a fellow transcendentalist.


title: Ralph Waldo Emerson

text: Emerson was born in Boston, Massachusetts, on May 25, 1803, a son of Ruth Haskins and the Rev. William Emerson, a Unitarian minister. He was named after his mother's brother Ralph and his father's great-grandmother Rebecca Waldo. Ralph Waldo was the second of five sons who survived into adulthood; the others were William, Edward, Robert Bulkeley, and Charles. Three other children—Phoebe, John Clarke, and Mary Caroline—died in childhood. Emerson was entirely of English ancestry, and his family had been in New England since the early colonial period.


title: Ralph Waldo Emerson

text: Emerson's father died from stomach cancer on May 12, 1811, less than two weeks before Emerson's eighth birthday. Emerson was raised by his mother, with the help of the other women in the family; his aunt Mary Moody Emerson in particular had a profound effect on him. She lived with the family off and on and maintained a constant correspondence with Emerson until her death in 1863.


title: Ralph Waldo Emerson

text: Emerson's formal schooling began at the Boston Latin School in 1812, when he was nine. In October 1817, at age 14, Emerson went to Harvard College and was appointed freshman messenger for the president, requiring Emerson to fetch delinquent students and send messages to faculty. Midway through his junior year, Emerson began keeping a list of books he had read and started a journal in a series of notebooks that would be called "Wide World". He took outside jobs to cover his school expenses, including as a waiter for the Junior Commons and as an occasional teacher working with his uncle Samuel and aunt Sarah Ripley in Waltham, Massachusetts. By his senior year, Emerson decided to go by his middle name, Waldo. Emerson served as Class Poet; as was custom, he presented an original poem on Harvard's Class Day, a month before his official graduation on August 29, 1821, when he was 18. He did not stand out as a student and graduated in the exact middle of his class of 59 people. In the early 1820s, Emerson was a teacher at the School for Young Ladies (which was run by his brother William). He would next spend two years living in a cabin in the Canterbury section of Roxbury, Massachusetts, where he wrote and studied nature. In his honor, this area is now called Schoolmaster Hill in Boston's Franklin Park.


title: Ralph Waldo Emerson

text: In 1826, faced with poor health, Emerson went to seek a warmer climate. He first went to Charleston, South Carolina, but found the weather was still too cold. He then went farther south, to St. Augustine, Florida, where he took long walks on the beach and began writing poetry. While in St. Augustine he made the acquaintance of Prince Achille Murat, the nephew of Napoleon Bonaparte. Murat was two years his senior; they became good friends and enjoyed each other's company. The two engaged in enlightening discussions of religion, society, philosophy, and government. Emerson considered Murat an important figure in his intellectual education.


title: Ralph Waldo Emerson

text: While in St. Augustine, Emerson had his first encounter with slavery. At one point, he attended a meeting of the Bible Society while a slave auction was taking place in the yard outside. He wrote, "One ear therefore heard the glad tidings of great joy, whilst the other was regaled with 'Going, gentlemen, going!'"


title: Ralph Waldo Emerson

text: After Harvard, Emerson assisted his brother William in a school for young women established in their mother's house, after he had established his own school in Chelmsford, Massachusetts; when his brother William went to Göttingen to study law in mid-1824, Ralph Waldo closed the school but continued to teach in Cambridge, Massachusetts, until early 1825. Emerson was accepted into the Harvard Divinity School in late 1824, and was inducted into Phi Beta Kappa in 1828. Emerson's brother Edward, two years younger than he, entered the office of the lawyer Daniel Webster, after graduating from Harvard first in his class. Edward's physical health began to deteriorate, and he soon suffered a mental collapse as well; he was taken to McLean Asylum in June 1828 at age 25. Although he recovered his mental equilibrium, he died in 1834, apparently from long-standing tuberculosis. Another of Emerson's bright and promising younger brothers, Charles, born in 1808, died in 1836, also of tuberculosis, making him the third young person in Emerson's innermost circle to die in a period of a few years.


title: Ralph Waldo Emerson

text: Emerson met his first wife, Ellen Louisa Tucker, in Concord, New Hampshire, on Christmas Day, 1827, and married her when she was 18 two years later. The couple moved to Boston, with Emerson's mother, Ruth, moving with them to help take care of Ellen, who was already ill with tuberculosis. Less than two years after that, on February 8, 1831, Ellen died, at the age of 20, after uttering her last words: "I have not forgotten the peace and joy". Emerson was heavily affected by her death and visited her grave in Roxbury daily. In a journal entry dated March 29, 1832, he wrote, "I visited Ellen's tomb & opened the coffin".


title: Ralph Waldo Emerson

text: Boston's Second Church invited Emerson to serve as its junior pastor, and he was ordained on January 11, 1829. His initial salary was $1,200 per year (), increasing to $1,400 in July, but with his church role he took on other responsibilities: he was the chaplain of the Massachusetts legislature and a member of the Boston school committee. His church activities kept him busy, though during this period, facing the imminent death of his wife, he began to doubt his own beliefs.


title: Ralph Waldo Emerson

text: After his wife's death, he began to disagree with the church's methods, writing in his journal in June 1832, "I have sometimes thought that, in order to be a good minister, it was necessary to leave the ministry. The profession is antiquated. In an altered age, we worship in the dead forms of our forefathers". His disagreements with church officials over the administration of the Communion service and misgivings about public prayer eventually led to his resignation in 1832. As he wrote, "This mode of commemorating Christ is not suitable to me. That is reason enough why I should abandon it". As one Emerson scholar has pointed out, "Doffing the decent black of the pastor, he was free to choose the gown of the lecturer and teacher, of the thinker not confined within the limits of an institution or a tradition".


title: Ralph Waldo Emerson

text: Emerson toured Europe in 1833 and later wrote of his travels in "English Traits" (1856). He left aboard the brig "Jasper" on Christmas Day, 1832, sailing first to Malta. During his European trip, he spent several months in Italy, visiting Rome, Florence and Venice, among other cities. When in Rome, he met with John Stuart Mill, who gave him a letter of recommendation to meet Thomas Carlyle. He went to Switzerland, and had to be dragged by fellow passengers to visit Voltaire's home in Ferney, "protesting all the way upon the unworthiness of his memory". He then went on to Paris, a "loud modern New York of a place", where he visited the Jardin des Plantes. He was greatly moved by the organization of plants according to Jussieu's system of classification, and the way all such objects were related and connected. As Robert D. Richardson says, "Emerson's moment of insight into the interconnectedness of things in the Jardin des Plantes was a moment of almost visionary intensity that pointed him away from theology and toward science".


title: Ralph Waldo Emerson

text: Moving north to England, Emerson met William Wordsworth, Samuel Taylor Coleridge, and Thomas Carlyle. Carlyle in particular was a strong influence on him; Emerson would later serve as an unofficial literary agent in the United States for Carlyle, and in March 1835, he tried to persuade Carlyle to come to America to lecture. The two maintained a correspondence until Carlyle's death in 1881.


title: Ralph Waldo Emerson

text: Emerson returned to the United States on October 9, 1833, and lived with his mother in Newton, Massachusetts. In October 1834, he moved to Concord, Massachusetts, to live with his step-grandfather, Dr. Ezra Ripley, at what was later named The Old Manse. Given the budding Lyceum movement, which provided lectures on all sorts of topics, Emerson saw a possible career as a lecturer. On November 5, 1833, he made the first of what would eventually be some 1,500 lectures, "The Uses of Natural History", in Boston. This was an expanded account of his experience in Paris. In this lecture, he set out some of his important beliefs and the ideas he would later develop in his first published essay, "Nature":


title: Ralph Waldo Emerson

text: On January 24, 1835, Emerson wrote a letter to Lydia Jackson proposing marriage. Her acceptance reached him by mail on the 28th. In July 1835, he bought a house on the Cambridge and Concord Turnpike in Concord, Massachusetts, which he named Bush; it is now open to the public as the Ralph Waldo Emerson House. Emerson quickly became one of the leading citizens in the town. He gave a lecture to commemorate the 200th anniversary of the town of Concord on September 12, 1835. Two days later, he married Jackson in her home town of Plymouth, Massachusetts, and moved to the new home in Concord together with Emerson's mother on September 15.

text: Emerson quickly changed his wife's name to Lidian, and would call her Queenie, and sometimes Asia, and she called him Mr. Emerson. Their children were Waldo, Ellen, Edith, and Edward Waldo Emerson. Edward Waldo Emerson was the father of Raymond Emerson. Ellen was named for his first wife, at Lidian's suggestion.

text: Emerson was poor when he was at Harvard, but was later able to support his family for much of his life. He inherited a fair amount of money after his first wife's death, though he had to file a lawsuit against the Tucker family in 1836 to get it. He received $11,600 in May 1834 (), and a further $11,674.49 in July 1837 (). In 1834, he considered that he had an income of $1,200 a year from the initial payment of the estate, equivalent to what he had earned as a pastor.

text: On September 8, 1836, the day before the publication of "Nature", Emerson met with Frederic Henry Hedge, George Putnam, and George Ripley to plan periodic gatherings of other like-minded intellectuals. This was the beginning of the Transcendental Club, which served as a center for the movement. Its first official meeting was held on September 19, 1836. On September 1, 1837, women attended a meeting of the Transcendental Club for the first time. Emerson invited Margaret Fuller, Elizabeth Hoar, and Sarah Ripley for dinner at his home before the meeting to ensure that they would be present for the evening get-together. Fuller would prove to be an important figure in transcendentalism.


title: Ralph Waldo Emerson

text: Emerson anonymously sent his first essay; "Nature" to James Munroe and Company to be published on September 9, 1836. A year later, on August 31, 1837, he delivered his now-famous Phi Beta Kappa address, "The American Scholar", then entitled "An Oration, Delivered before the Phi Beta Kappa Society at Cambridge"; it was renamed for a collection of essays (which included the first general publication of "Nature") in 1849. Friends urged him to publish the talk, and he did so at his own expense, in an edition of 500 copies, which sold out in a month. In the speech, Emerson declared literary independence in the United States and urged Americans to create a writing style all their own, free from Europe. James Russell Lowell, who was a student at Harvard at the time, called it "an event without former parallel on our literary annals". Another member of the audience, Reverend John Pierce, called it "an apparently incoherent and unintelligible address".


title: Ralph Waldo Emerson

text: In 1837, Emerson befriended Henry David Thoreau. Though they had likely met as early as 1835, in the fall of 1837, Emerson asked Thoreau, "Do you keep a journal?" The question went on to be a lifelong inspiration for Thoreau. Emerson's own journal was published in 16 large volumes, in the definitive Harvard University Press edition issued between 1960 and 1982. Some scholars consider the journal to be Emerson's key literary work.


title: Ralph Waldo Emerson

text: In March 1837, Emerson gave a series of lectures on the philosophy of history at the Masonic Temple in Boston. This was the first time he managed a lecture series on his own, and it was the beginning of his career as a lecturer. The profits from this series of lectures were much larger than when he was paid by an organization to talk, and he continued to manage his own lectures often throughout his lifetime. He eventually gave as many as 80 lectures a year, traveling across the northern United States as far as St. Louis, Des Moines, Minneapolis, and California.


title: Ralph Waldo Emerson

text: On July 15, 1838, Emerson was invited to Divinity Hall, Harvard Divinity School, to deliver the school's graduation address, which came to be known as the "Divinity School Address". Emerson discounted biblical miracles and proclaimed that, while Jesus was a great man, he was not God: historical Christianity, he said, had turned Jesus into a "demigod, as the Orientals or the Greeks would describe Osiris or Apollo". His comments outraged the establishment and the general Protestant community. He was denounced as an atheist and a poisoner of young men's minds. Despite the roar of critics, he made no reply, leaving others to put forward a defense. He was not invited back to speak at Harvard for another thirty years.


title: Ralph Waldo Emerson

text: The transcendental group began to publish its flagship journal, "The Dial", in July 1840. They planned the journal as early as October 1839, but work did not begin until the first week of 1840. George Ripley was the managing editor. Margaret Fuller was the first editor, having been approached by Emerson after several others had declined the role. Fuller stayed on for about two years, when Emerson took over, using the journal to promote talented young writers including Ellery Channing and Thoreau.


title: Ralph Waldo Emerson

text: In 1841 Emerson published "Essays", his second book, which included the famous essay "Self-Reliance". His aunt called it a "strange medley of atheism and false independence", but it gained favorable reviews in London and Paris. This book, and its popular reception, more than any of Emerson's contributions to date laid the groundwork for his international fame.


title: Ralph Waldo Emerson

text: In January 1842 Emerson's first son, Waldo, died of scarlet fever. Emerson wrote of his grief in the poem "Threnody" ("For this losing is true dying"), and the essay "Experience". In the same month, William James was born, and Emerson agreed to be his godfather.


title: Ralph Waldo Emerson

text: Bronson Alcott announced his plans in November 1842 to find "a farm of a hundred acres in excellent condition with good buildings, a good orchard and grounds". Charles Lane purchased a farm in Harvard, Massachusetts, in May 1843 for what would become Fruitlands, a community based on Utopian ideals inspired in part by transcendentalism. The farm would run based on a communal effort, using no animals for labor; its participants would eat no meat and use no wool or leather. Emerson said he felt "sad at heart" for not engaging in the experiment himself. Even so, he did not feel Fruitlands would be a success. "Their whole doctrine is spiritual", he wrote, "but they always end with saying, Give us much land and money". Even Alcott admitted he was not prepared for the difficulty in operating Fruitlands. "None of us were prepared to actualize practically the ideal life of which we dreamed. So we fell apart", he wrote. After its failure, Emerson helped buy a farm for Alcott's family in Concord which Alcott named "Hillside".


title: Ralph Waldo Emerson

text: "The Dial" ceased publication in April 1844; Horace Greeley reported it as an end to the "most original and thoughtful periodical ever published in this country".


title: Ralph Waldo Emerson

text: In 1844, Emerson published his second collection of essays, "Essays: Second Series". This collection included "The Poet", "Experience", "Gifts", and an essay entitled "Nature", a different work from the 1836 essay of the same name.


title: Ralph Waldo Emerson

text: Emerson made a living as a popular lecturer in New England and much of the rest of the country. He had begun lecturing in 1833; by the 1850s he was giving as many as 80 lectures per year. He addressed the Boston Society for the Diffusion of Useful Knowledge and the Gloucester Lyceum, among others. Emerson spoke on a wide variety of subjects, and many of his essays grew out of his lectures. He charged between $10 and $50 for each appearance, bringing him as much as $2,000 in a typical winter lecture season. This was more than his earnings from other sources. In some years, he earned as much as $900 for a series of six lectures, and in another, for a winter series of talks in Boston, he netted $1,600. He eventually gave some 1,500 lectures in his lifetime. His earnings allowed him to expand his property, buying of land by Walden Pond and a few more acres in a neighboring pine grove. He wrote that he was "landlord and water lord of 14 acres, more or less".


title: Ralph Waldo Emerson

text: Emerson was introduced to Indian philosophy through the works of the French philosopher Victor Cousin. In 1845, Emerson's journals show he was reading the "Bhagavad Gita" and Henry Thomas Colebrooke's "Essays on the Vedas". He was strongly influenced by Vedanta, and much of his writing has strong shades of nondualism. One of the clearest examples of this can be found in his essay "The Over-soul":


title: Ralph Waldo Emerson

text: The central message Emerson drew from his Asian studies was that "the purpose of life was spiritual transformation and direct experience of divine power, here and now on earth."


title: Ralph Waldo Emerson

text: In 1847–48, he toured the British Isles. He also visited Paris between the French Revolution of 1848 and the bloody June Days. When he arrived, he saw the stumps of trees that had been cut down to form barricades in the February riots. On May 21, he stood on the Champ de Mars in the midst of mass celebrations for concord, peace and labor. He wrote in his journal, "At the end of the year we shall take account, & see if the Revolution was worth the trees." The trip left an important imprint on Emerson's later work. His 1856 book "English Traits" is based largely on observations recorded in his travel journals and notebooks. Emerson later came to see the American Civil War as a "revolution" that shared common ground with the European revolutions of 1848.


title: Ralph Waldo Emerson

text: In February 1852 Emerson and James Freeman Clarke and William Henry Channing edited an edition of the works and letters of Margaret Fuller, who had died in 1850. Within a week of her death, her New York editor, Horace Greeley, suggested to Emerson that a biography of Fuller, to be called "Margaret and Her Friends", be prepared quickly "before the interest excited by her sad decease has passed away". Published under the title "The Memoirs of Margaret Fuller Ossoli", Fuller's words were heavily censored or rewritten. The three editors were not concerned about accuracy; they believed public interest in Fuller was temporary and that she would not survive as a historical figure. Even so, it was the best-selling biography of the decade and went through thirteen editions before the end of the century.


title: Ralph Waldo Emerson

text: Walt Whitman published the innovative poetry collection "Leaves of Grass" in 1855 and sent a copy to Emerson for his opinion. Emerson responded positively, sending Whitman a flattering five-page letter in response. Emerson's approval helped the first edition of "Leaves of Grass" stir up significant interest and convinced Whitman to issue a second edition shortly thereafter. This edition quoted a phrase from Emerson's letter, printed in gold leaf on the cover: "I Greet You at the Beginning of a Great Career". Emerson took offense that this letter was made public and later was more critical of the work.


title: Ralph Waldo Emerson

text: Ralph Waldo Emerson, in the summer of 1858, would venture into the great wilderness of upstate New York.


title: Ralph Waldo Emerson

text: Joining him were nine of the most illustrious intellectuals ever to camp out in the Adirondacks to connect with nature: Louis Agassiz, James Russell Lowell, John Holmes, Horatio Woodman, Ebenezer Rockwell Hoar, Jeffries Wyman, Estes Howe, Amos Binney, and William James Stillman. Invited, but unable to make the trip for diverse reasons, were: Oliver Wendell Holmes, Henry Wadsworth Longfellow, and Charles Eliot Norton, all members of the Saturday Club (Boston, Massachusetts).


title: Ralph Waldo Emerson

text: This social club was mostly a literary membership that met the last Saturday of the month at the Boston Parker House Hotel (Omni Parker House). William James Stillman was a painter and founding editor of an art journal called the Crayon. Stillman was born and grew up in Schenectady which was just south of the Adirondack mountains. He would later travel there to paint the wilderness landscape and to fish and hunt. He would share his experiences in this wilderness to the members of the Saturday Club, raising their interest in this unknown region.


title: Ralph Waldo Emerson

text: James Russell Lowell and William Stillman would lead the effort to organize a trip to the Adirondacks. They would begin their journey on August 2, 1858, traveling by train, steam boat, stagecoach, and canoe guide boats. News that these cultured men were living like "Sacs and Sioux" in the wilderness appeared in newspapers across the nation. This would become known as the ""Philosophers Camp"".


title: Ralph Waldo Emerson

text: This event was a landmark in the nineteenth-century intellectual movement, linking nature with art and literature.


title: Ralph Waldo Emerson

text: Although much has been written over many years by scholars and biographers of Emerson's life, little has been written of what has become known as the "Philosophers Camp" at Follensbee Pond. Yet, his epic poem "Adirondac" reads like a journal of his day to day detailed description of adventures in the wilderness with his fellow members of the Saturday Club. This two week camping excursion (1858 in the Adirondacks) brought him face to face with a true wilderness, something he spoke of in his essay "Nature", published in 1836. He said, "in the wilderness I find something more dear and connate than in streets or villages".


title: Ralph Waldo Emerson

text: Emerson was staunchly opposed to slavery, but he did not appreciate being in the public limelight and was hesitant about lecturing on the subject. In the years leading up to the Civil War, he did give a number of lectures, however, beginning as early as November 1837. A number of his friends and family members were more active abolitionists than he, at first, but from 1844 on he more actively opposed slavery. He gave a number of speeches and lectures, and welcomed John Brown to his home during Brown's visits to Concord. He voted for Abraham Lincoln in 1860, but was disappointed that Lincoln was more concerned about preserving the Union than eliminating slavery outright. Once the American Civil War broke out, Emerson made it clear that he believed in immediate emancipation of the slaves.


title: Ralph Waldo Emerson

text: Around this time, in 1860, Emerson published "The Conduct of Life", his seventh collection of essays. It "grappled with some of the thorniest issues of the moment," and "his experience in the abolition ranks is a telling influence in his conclusions." In these essays Emerson strongly embraced the idea of war as a means of national rebirth: "Civil war, national bankruptcy, or revolution, [are] more rich in the central tones than languid years of prosperity."


title: Ralph Waldo Emerson

text: Emerson visited Washington, D.C, at the end of January 1862. He gave a public lecture at the Smithsonian on January 31, 1862, and declared:, "The South calls slavery an institution ... I call it destitution ... Emancipation is the demand of civilization". The next day, February 1, his friend Charles Sumner took him to meet Lincoln at the White House. Lincoln was familiar with Emerson's work, having previously seen him lecture. Emerson's misgivings about Lincoln began to soften after this meeting. In 1865, he spoke at a memorial service held for Lincoln in Concord: "Old as history is, and manifold as are its tragedies, I doubt if any death has caused so much pain as this has caused, or will have caused, on its announcement." Emerson also met a number of high-ranking government officials, including Salmon P. Chase, the secretary of the treasury; Edward Bates, the attorney general; Edwin M. Stanton, the secretary of war; Gideon Welles, the secretary of the navy; and William Seward, the secretary of state.


title: Ralph Waldo Emerson

text: On May 6, 1862, Emerson's protégé Henry David Thoreau died of tuberculosis at the age of 44. Emerson delivered his eulogy. He often referred to Thoreau as his best friend, despite a falling-out that began in 1849 after Thoreau published "A Week on the Concord and Merrimack Rivers". Another friend, Nathaniel Hawthorne, died two years after Thoreau, in 1864. Emerson served as a pallbearer when Hawthorne was buried in Concord, as Emerson wrote, "in a pomp of sunshine and verdure".


title: Ralph Waldo Emerson

text: He was elected a Fellow of the American Academy of Arts and Sciences in 1864. In 1867, he was elected as a member to the American Philosophical Society.


title: Ralph Waldo Emerson

text: Starting in 1867, Emerson's health began declining; he wrote much less in his journals. Beginning as early as the summer of 1871 or in the spring of 1872, he started experiencing memory problems and suffered from aphasia. By the end of the decade, he forgot his own name at times and, when anyone asked how he felt, he responded, "Quite well; I have lost my mental faculties, but am perfectly well".


title: Ralph Waldo Emerson

text: In the spring of 1871, Emerson took a trip on the transcontinental railroad, barely two years after its completion. Along the way and in California he met a number of dignitaries, including Brigham Young during a stopover in Salt Lake City. Part of his California visit included a trip to Yosemite, and while there he met a young and unknown John Muir, a signature event in Muir's career.


title: Ralph Waldo Emerson

text: Emerson's Concord home caught fire on July 24, 1872. He called for help from neighbors and, giving up on putting out the flames, all tried to save as many objects as possible. The fire was put out by Ephraim Bull Jr., the one-armed son of Ephraim Wales Bull. Donations were collected by friends to help the Emersons rebuild, including $5,000 gathered by Francis Cabot Lowell, another $10,000 collected by LeBaron Russell Briggs, and a personal donation of $1,000 from George Bancroft. Support for shelter was offered as well; though the Emersons ended up staying with family at the Old Manse, invitations came from Anne Lynch Botta, James Elliot Cabot, James T. Fields and Annie Adams Fields. The fire marked an end to Emerson's serious lecturing career; from then on, he would lecture only on special occasions and only in front of familiar audiences.


title: Ralph Waldo Emerson

text: While the house was being rebuilt, Emerson took a trip to England, continental Europe, and Egypt. He left on October 23, 1872, along with his daughter Ellen, while his wife Lidian spent time at the Old Manse and with friends. Emerson and his daughter Ellen returned to the United States on the ship "Olympus" along with friend Charles Eliot Norton on April 15, 1873. Emerson's return to Concord was celebrated by the town, and school was canceled that day.


title: Ralph Waldo Emerson

text: In late 1874, Emerson published an anthology of poetry entitled "Parnassus", which included poems by Anna Laetitia Barbauld, Julia Caroline Dorr, Jean Ingelow, Lucy Larcom, Jones Very, as well as Thoreau and several others. Originally, the anthology had been prepared as early as the fall of 1871, but it was delayed when the publishers asked for revisions.


title: Ralph Waldo Emerson

text: The problems with his memory had become embarrassing to Emerson and he ceased his public appearances by 1879. In reply to an invitation to a retirement celebration for Octavius B. Frothingham, he wrote, "“I am not in condition to make visits, or take any part in conversation. Old age has rushed on me in the last year, and tied my tongue, and hid my memory, and thus made it a duty to stay at home.”" The New York Times quoted his reply and noted that his regrets were read aloud at the celebration. Holmes wrote of the problem saying, "Emerson is afraid to trust himself in society much, on account of the failure of his memory and the great difficulty he finds in getting the words he wants. It is painful to witness his embarrassment at times".


title: Ralph Waldo Emerson

text: On April 21, 1882, Emerson was found to be suffering from pneumonia. He died six days later. Emerson is buried in Sleepy Hollow Cemetery, Concord, Massachusetts. He was placed in his coffin wearing a white robe given by the American sculptor Daniel Chester French.


title: Ralph Waldo Emerson

text: Emerson's religious views were often considered radical at the time. He believed that all things are connected to God and, therefore, all things are divine. Critics believed that Emerson was removing the central God figure; as Henry Ware Jr. said, Emerson was in danger of taking away "the Father of the Universe" and leaving "but a company of children in an orphan asylum". Emerson was partly influenced by German philosophy and Biblical criticism. His views, the basis of Transcendentalism, suggested that God does not have to reveal the truth, but that the truth could be intuitively experienced directly from nature. When asked his religious belief, Emerson stated, "I am more of a Quaker than anything else. I believe in the 'still, small voice', and that voice is Christ within us."


title: Ralph Waldo Emerson

text: Emerson was a supporter of the spread of community libraries in the 19th century, having this to say of them: "Consider what you have in the smallest chosen library. A company of the wisest and wittiest men that could be picked out of all civil countries, in a thousand years, have set in best order the results of their learning and wisdom."


title: Ralph Waldo Emerson

text: Emerson had a number of romantic interests in various women throughout his life, such as Anna Barker and Caroline Sturgis. During his early years at Harvard (around age 14-16), he wrote erotic poetry about a fellow classmate named Martin Gay.


title: Ralph Waldo Emerson

text: Emerson did not become an ardent abolitionist until 1844, though his journals show he was concerned with slavery beginning in his youth, even dreaming about helping to free slaves. In June 1856, shortly after Charles Sumner, a United States Senator, was beaten for his staunch abolitionist views, Emerson lamented that he himself was not as committed to the cause. He wrote, "There are men who as soon as they are born take a bee-line to the axe of the inquisitor. ... Wonderful the way in which we are saved by this unfailing supply of the moral element". After Sumner's attack, Emerson began to speak out about slavery. "I think we must get rid of slavery, or we must get rid of freedom", he said at a meeting at Concord that summer. Emerson used slavery as an example of a human injustice, especially in his role as a minister. In early 1838, provoked by the murder of an abolitionist publisher from Alton, Illinois named Elijah Parish Lovejoy, Emerson gave his first public antislavery address. As he said, "It is but the other day that the brave Lovejoy gave his breast to the bullets of a mob, for the rights of free speech and opinion, and died when it was better not to live". John Quincy Adams said the mob-murder of Lovejoy "sent a shock as of any earthquake throughout this continent". However, Emerson maintained that reform would be achieved through moral agreement rather than by militant action. By August 1, 1844, at a lecture in Concord, he stated more clearly his support for the abolitionist movement: "We are indebted mainly to this movement, and to the continuers of it, for the popular discussion of every point of practical ethics".


title: Ralph Waldo Emerson

text: Emerson is often known as one of the most liberal democratic thinkers of his time who believed that through the democratic process, slavery should be abolished. While being an avid abolitionist who was known for his criticism of the legality of slavery, Emerson struggled with the implications of race. His usual liberal leanings did not clearly translate when it came to believing that all races had equal capability or function, which was a common conception for the period in which he lived. Many critics believe that it was his views on race that inhibited him from becoming an abolitionist earlier in his life and also inhibited him from being more active in the antislavery movement. Much of his early life, he was silent on the topic of race and slavery. Not until he was well into his 30s did Emerson begin to publish writings on race and slavery, and not until he was in his late 40s and 50s did he became known as an antislavery activist.


title: Ralph Waldo Emerson

text: During his early life, Emerson seemed to develop a hierarchy of races based on faculty to reason or rather, whether African slaves were distinguishably equal to white men based on their ability to reason. In a journal entry written in 1822, Emerson wrote about a personal observation: "It can hardly be true that the difference lies in the attribute of reason. I saw ten, twenty, a hundred large lipped, lowbrowed black men in the streets who, except in the mere matter of language, did not exceed the sagacity of the elephant. Now is it true that these were created superior to this wise animal, and designed to control it? And in comparison with the highest orders of men, the Africans will stand so low as to make the difference which subsists between themselves & the sagacious beasts inconsiderable."


title: Ralph Waldo Emerson

text: As with many supporters of slavery, during his early years, Emerson seems to have thought that the faculties of African slaves were not equal to those of white slave-owners. But this belief in racial inferiorities did not make Emerson a supporter of slavery. Emerson wrote later that year that "No ingenious sophistry can ever reconcile the unperverted mind to the pardon of Slavery; nothing but tremendous familiarity, and the bias of private interest". Emerson saw the removal of people from their homeland, the treatment of slaves, and the self-seeking benefactors of slaves as gross injustices. For Emerson, slavery was a moral issue, while superiority of the races was an issue he tried to analyze from a scientific perspective based what he believed to be inherited traits.


title: Ralph Waldo Emerson

text: Emerson saw himself as a man of "Saxon descent". In a speech given in 1835 titled "Permanent Traits of the English National Genius", he said, "The inhabitants of the United States, especially of the Northern portion, are descended from the people of England and have inherited the traits of their national character". He saw direct ties between race based on national identity and the inherent nature of the human being. White Americans who were native-born in the United States and of English ancestry were categorized by him as a separate "race", which he thought had a position of being superior to other nations. His idea of race was based on a shared culture, environment, and history. He believed that native-born Americans of English descent were superior to European immigrants, including the Irish, French, and Germans, and also as being superior to English people from England, whom he considered a close second and the only really comparable group.


title: Ralph Waldo Emerson

text: Later in his life, Emerson's ideas on race changed when he became more involved in the abolitionist movement while at the same time he began to more thoroughly analyze the philosophical implications of race and racial hierarchies. His beliefs shifted focus to the potential outcomes of racial conflicts. Emerson's racial views were closely related to his views on nationalism and national superiority, which was a common view in the United States at that time. Emerson used contemporary theories of race and natural science to support a theory of race development. He believed that the current political battle and the current enslavement of other races was an inevitable racial struggle, one that would result in the inevitable union of the United States. Such conflicts were necessary for the dialectic of change that would eventually allow the progress of the nation. In much of his later work, Emerson seems to allow the notion that different European races will eventually mix in America. This hybridization process would lead to a superior race that would be to the advantage of the superiority of the United States.
