Living in Time presents chapters on each of Bergson's four major works, explaining his theories of time, perception, memory, and panpsychic consciousness, his innovative concept of virtual existence, his objection to Darwin, his controversy with Einstein, his philosophy of creative evolution, and his social philosophy of closed and open society. In particular Allen focusses on Bergson's powerful ideas on time. The book's conclusion discusses the question of Bergson and naturalism and summarizes the ontology of the virtual that emerges as a core part of Bergson's thought.
