The twentieth century – with its unprecedented advances in technology and scientific understanding – saw the birth of a distinctively new and 'modern' age. Henri Bergson stood as one of the most important philosophical voices of that tumultuous time. An intellectual celebrity in his own life time, his work was widely discussed by such thinkers as William James, Alfred North Whitehead and Bertrand Russell, as well as having a profound influence on modernist writers such as Wallace Stevens, Willa Cather and Wyndham Lewis and later thinkers, most notably Gilles Deleuze.

Key Writings brings together Bergson's most essential writings in a single volume, including crucial passages from such major work as Time and Free Will, Matter and Memory, Creative Evolution, Mind-Energy, The Creative Mind, The Two Sources of Morality and Religion and Laughter. The book also includes Bergson's correspondences with William James and a chronology of his life and work.
