This famous essay first appeared in the Revue de Metaphysique et de Morale in January, 1903. Published in book form in 1912, it has been translated into many languages and constitutes what many philosophers consider to be the best introduction to Bergson’s philosophy. Strictly speaking, the title is misleading. The book is not an introduction to metaphysics but rather an introduction to the method of metaphysics, or intuition. Although there is a close relation between Bergson’s view of the world and his conception of the intuitive method, the emphasis in this book is predominantly on the latter. Metaphysics, in fact, is defined by Bergson as the science that uses intuition.
