We are in the midst of a return to Henri Bergson - the French philosopher whose influence touches the fields of continental philosophy, literary theory and art theory. This revival of interest in his work could even be called a full-blown Bergson renaissance. Tano S. Posteraro contributes to this increasingly serious study of Bergson's philosophy with a tight focus on Bergson's theory of evolution. He presents an alternative Bergson: not a phenomenologist whose central concern is the conscious experience of lived time or the lived body in time, but a systematic philosopher of biology with a robust, prescient and largely workable evolutionary programme.
