An Introduction to Metaphysics (Henri Bergson Centennial)

the long version

"This book is the key text for understanding the development of Bergson's thought from his early treatises on duration to the extension of this concept towards a general cosmology and an ethico-political ontology. In a new critical edition of this crucial work, the original authorised translation by T.E. Hulme has been restored and supplemented with new translations of Bergson's later amendments to the text, a guide to further reading and a new introduction."--Jacket.
