Henri Bergson was born in the year that Darwin published the Origin of the Species. He could not have imagined the philosophical impact of evolutionary theory, which is now so great that Bergson's philosophy, which emphasizes "creative evolution," is experiencing a significant revival. The basic principles that Bergson articulates, especially his way of thinking about reality as a dynamic process and his view of human beings as creative and evolving, should be helpful to anyone who seeks to go beyond simply dealing with the practical demands of daily life and consider the nature of things.
