Bergson, Henri. Introduction to Metaphysics. New York: Wisdom Library/Philosophical Library, 1961.

Abstract

A discourse by the eminent French philosopher that defines the meaning of the terms "metaphysics" and "science." The author states that one is free to give words the meaning one wishes if one is careful to define that meaning; nothing hinders one from calling any kind of knowledge "science" or "philosophy," as has long been done; one could indeed include everything in metaphysics. Professor Bergson then shows that knowledge proceeds  in a special direction when it frees itself of any thoughts of relation and comparison in order to be in sympathy with reality, and demonstrates how this approach is particularly suitable to the study of mind as opposed to the study of matter.
