Time and Free Will argues that lived time (durée) is a qualitative flow, not the homogeneous, spatialized time of mechanics. Through analyses of intensity, the interpenetration of mental states, and the famous melody example, Bergson critiques psychophysics' arithmetic of the mind and the determinism it supports. In lucid, image-rich prose, the essay straddles psychology and metaphysics, opposing late nineteenth-century positivism and associationism while inaugurating a distinct method of intuition. Henri Bergson (1859-1941), trained in mathematics at the École Normale Supérieure and shaped by Ravaisson and Boutroux, submitted this study as part of his 1889 doctoral theses. Dissatisfied with how calculus and physics spatialize time, and informed by close reading of psychophysics and British empiricism, he sought the immediate data of consciousness. These concerns anticipate his later accounts of memory and creative evolution, which would earn him the 1927 Nobel Prize. Recommended to readers probing freedom, agency, and temporality-from philosophers of mind and phenomenologists to psychologists wary of reductionism-this classic equips them with a precise vocabulary and vivid examples. Clear yet conceptually daring, it remains a compelling point of departure for rethinking what it means to live in time.
