A volume of Bergson's lectures and essays on the theory and philosophy of consciousness and memory, originally published in 1920. These articles were selected by the author with the view of illustrating his concept that reality is fundamentally and spiritual activity. Contents include: 'Life and Consciousness', 'The Soul and the body', 'Phantasms of the Living and Physical Research', 'Dreams', 'Memory of the Present and False Recognition', 'Intellectual Effort', and 'Brain and Thought: A Philosophical Illusion'. This classic work is being republished now in a new edition complete with a chapter From "Bergson And His Philosophy" by J. Alexander Gunn. Henri-Louis Bergson (1859-1941) was a French-Jewish philosopher. He had a significant influence on the tradition of continental philosophy during the first half of the twentieth century until World War II, and is famous for his idea that immediate experience and intuition are more important than abstract rationalism and science for understanding the nature of reality.
