Michel de Montaigne (28 February 1533 - 13 September 1592) was one of the most significant philosophers of the French Renaissance, known for popularizing the essay as a literary genre. His work is noted for its merging of casual anecdotes and autobiography with intellectual insight. His massive volume Essais contains some of the most influential essays ever written. During his lifetime, Montaigne was admired more as a statesman than as an author. The tendency in his essays to digress into anecdotes and personal ruminations was seen as detrimental to proper style rather than an innovation. In time, however, Montaigne came to be recognized as embodying, perhaps better than any other author of his time, the spirit of freely entertaining doubt that began to emerge at that time.
