The Inconstancy of the Self

Those who study human behaviour, Montaigne begins, find themselves most perplexed when they try to reconcile the contradictory actions of the same person. Historians reach for stable characters — this man was brave, that one treacherous — but the evidence keeps disrupting the story. The same person who charges into cannon fire is terrified of a spider. The brilliant philosopher is helpless before ordinary temptation. How do we square the circle?

We do not go, we are driven, Montaigne writes — like things that float on a current. We act when the occasion calls, we desire what presents itself, we become who circumstances demand. The person who seems consistent is either very lucky in the constancy of their circumstances, or they have done the rare philosophical work of establishing genuine principles in advance. Most of us, Montaigne includes himself, are creatures of the moment.

This is not despair but calibration. If the self is unstable, then self-knowledge must be perpetual rather than conclusive — an ongoing report rather than a final verdict. Montaigne's Essays enact this insight formally: they are not a systematic account of the self but a continuous stream of observations, qualifications, and reversals. To know yourself is to keep watching.

From Book II, Chapter I of the Essays. This essay opens the second book of the collection and establishes the methodological premise of Montaigne's entire project.
