Herbert Carr has written a small text which truly encapsulates Henri Bergson's philosophy. Each chapter doesn't just summarise his work but rather involves the reader properly within the work in just the way Bergson himself was able to do. This formed the basis of his approach which was closely connected to his concept of duration. This little booklet is not a critical text and generally does not compare Bergson's work with other philosophers, except where necessary, it simply works through his ideas in a participative manner. It is by far the best exposition of Bergson I have read other than reading Bergson himself. In fact, in some ways it is better because it is able to somehow express his ideas in a very clear way. For a reader new to Bergson's thought it is the ideal introduction and covers all of his major works.
