CREATIVE EVOLUTION is an expression introduced by H. Bergson (q.v.), and intimately connected with his philosophy (Creative Evolution, Eng. trans., 1922). It is intended to draw attention to the moment of spontaneous originality in nature, and especially in certain activities and experiences of mankind. The work of a great poet or painter clearly cannot be explained by merely mechanical forces. It cannot even be accounted for by explicitly conscious plans and purposes, for the great artist does not as a rule know in advance what the result will be, but is led to it gradually, step by step. This kind of activity, unfettered by mechanical forces a tergo or by explicitly preconceived ends a fronte, and yet resulting in something new, is typical of creative evolution. A somewhat similar trend of thought, at all events in respect of its opposition to purely mechanistic accounts of natu ral phenomena, has been maintained and made familiar in Eng land by C. Lloyd Morgan under the term Emergence (q.v.).
