… Informal Inquiries (2nd edition): Shakespeare’s Philosophy (2006).

Shakespeare was 28 when Montaigne died. The first edition of Florio’s English translation of Montaigne’s essays came out in 1603. It is altogether likely that Shakespeare read those essays. A healthy skepticism of reason’s works and pomps characterizes the outlook of both essayist and playwright. I think that in Montaigne Shakespeare found a kindred spirit.
