The book is a collection of a large number of short subjective treatments of various topics. Montaigne's stated goal is to describe man, and especially himself, with utter frankness. He finds the great variety and volatility of human nature to be its most basic features. He describes his own poor memory, his ability to solve problems and mediate conflicts without truly getting emotionally involved, his disdain for man's pursuit of lasting fame, and his attempts to detach himself from worldly things to prepare for death. He writes about his disgust with the religious conflicts of his time, his belief that humans are not able to attain true certainty (skepticism), and even alludes to cultural relativism, all rather modern notions. His long "Apology for Raymond Sebond" contains his famous motto, "What do I know?". Montaigne considered marriage necessary for the raising of children, but disliked the strong feelings of romantic love as being detrimental to true freedom. In education, he favored concrete examples and experience over the teaching of abstract knowledge that has to be accepted uncritically.
