Henri Bergson's (1859-1941) short essay on dreams is an interesting addition to the psychoanalyst's library. The philosopher described dreams as the direct link between sensation and memory. His studies of duration and movement had provided him with a broad basis for his theory. He surmised that dreams are constructed around what had been seen, said, or done. The elaboration he attributed to memory images collected and preserved since early childhood and involving 'the innermost depths of the unconscious'. Bergson gave this lecture on the 26th of March 1901, but made no direct reference in it to Freud's The Interpretation of Dreams. Wade Baskin has written an informative introduction to this small volume.
