difference between age of reason and age of enlightenment
Age of Enlightenment The Enlightenment (also known as the Age of Enlightenment or the Age of Reason;[1] in French: le Siècle des Lumières, lit. '"the Century of Lights"'; and in German: Aufklärung, "Enlightenment")[2] was an intellectual and philosophical movement that dominated the world of ideas in Europe during the 18th century, "The Century of Philosophy".[3]
Middle age According to the Oxford English Dictionary middle age is between 45 and 65:[2] "The period between early adulthood and old age, usually considered as the years from about 45 to 65." The US Census lists the category middle age from 45 to 65. Merriam-Webster lists middle age from 45 to 64,[3] while prominent psychologist Erik Erikson saw it starting a little earlier and defines middle adulthood as between 40 and 65. The Collins English Dictionary lists it between the ages of 40 and 60,[4] and the Diagnostic and Statistical Manual of Mental Disorders – the standard diagnostic manual of the American Psychiatric Association – used to define middle age as 40 to 60, but as of DSM-IV (1994) revised the definition upwards to 45 to 65.
