In one of his most important philosophical writings, Henri Bergson here discusses how the matter of the brain and the world external to the body create mental impressions and memories. Matter and Memory, first published in 1912, introduced the current selectionist theories of memory, which postulate that there is a part of the brain that generates all possible images to be stored in memory and a part of the brain that chooses which images to store. Crossing academic disciplines and touching on matters that concern us all-how do we remember, and why?-this essential work will enthrall students of philosophy and psychology and lay readers alike.French philosopher HENRI BERGSON (1859-1941) was awarded the Nobel Prize for Literature in 1927, and is said to have influenced thinkers such as Marcel Proust, William James, Santayana, and Martin Heidegger. Among his works are Matter and Memory (1896), An Introduction to Metaphysics (1903), and The Two Sources of Morality and Religion (1932).
