The three parts of the Criticón, published in 1651, 1653, and 1657, achieved fame in Europe, especially in German-speaking countries.
It is, without a doubt, the author's masterpiece and one of the great works of the Siglo de Oro.
It is a lengthy allegorical novel with philosophical overtones.
It recalls the Byzantine style of novel in its many vicissitudes and in the numerous adventures to which the characters are subjected, as well as the picaresque novel in its satirical take on society, as evidenced in the long pilgrimage undertaken by the main characters, Critilo, the "critical man" who personifies disillusionment, and Andrenio, the "natural man" who represents innocence and primitive impulses.
The author constantly exhibits a perspectivist technique that unfolds according to the criteria or points of view of both characters, but in an antithetical rather than plural way as in Miguel de Cervantes.
The novel reveals a philosophy, pessimism, with which one of its greatest readers and admirers, the 19th century German philosopher Arthur Schopenhauer, identified.

The following is a summary of the Criticón, reduced almost to the point of a sketch, of a complex work that demands detailed study.

Critilo, man of the world, is shipwrecked on the coast of the island of Santa Elena, where he meets Andrenio, the natural man, who has grown up completely ignorant  of civilization.
Together they undertake a long voyage to the Isle of Immortality, travelling the long and prickly road of life.
In the first part, "En la primavera de la niñez" ("In the Spring of Childhood"), they join the royal court, where they suffer all manner of disappointments; in the second part, "En el otoño de la varonil edad" ("In the Autumn of the Age of Manliness"), they pass through Aragon, where they visit the house of Salastano (an anagram of the name of Gracián's friend Lastanosa), and travel to France, which the author calls the "wasteland of Hipocrinda", populated entirely by hypocrites and dunces, ending with a visit to a house of lunatics.
In the third part, "En el invierno de la vejez" ("In the Winter of Old Age"), they arrive in Rome, where they encounter an academy where they meet the most inventive of men, arriving finally at the Isle of Immortality.
He is intelligent and contributed greatly to the world.
One of his most famous phrases is "Respect yourself if you would have others respect you."
