Peter Burke provides a brilliantly concise summary of the historical context of Montaigne's life and work, and of the work itself. His short well written chapters on Montaigne's humanism, skepticism, religion, politics, psychology and so on focus on defining what were Montaigne's positions in each of these areas. Burke compares Montaigne's ideas and his particular skepticism with those of contemporaries and with classical philosophers who were Montaigne's prime sources of reference.
This analytical structure boxes Burke into a presentation that largely misses what made Montaigne a great philosopher. Yes, he had some tentative assertions and positions, but what makes him stand out in the Western tradition is that unlike almost anyone except possibly David Hume, he did not come to a final dogmatic assertion of what is truth. Even Socrates, with whom Montaigne could be compared, developed at length (at least in Plato's version) the claim that an ideal Republic should be governed by... who else, philosophers. Montaigne, who actually worked in government, made no such assertions.
Montaigne is an inspiration to those of us who believe that philosophy is not (only) about categorizing statements, but about considering what is the right way to live and to think - the process of reflection, rather than a final conclusion.
Nourished by a rich knowledge of the classics, and stimulated by recent cultural discoveries from the exploration of America - materials that provided an inexhaustible store of examples and counterexamples to any dogmatic claim - Montaigne embodied the questioning, thoughtful, reflective, good humored life of a humane and generous spirit.
Read Burke for the background, read him quickly, and then get on to Montaigne's Essays - a word he coined to represent that they were trials, explorations, reflections rather than an attempt to establish any definitive position about his colorful, wide range of topics.
