An interesting Neo-Lamarckist view on evolution, the notion that an organism can pass on to its offspring physical characteristics that the parent organism acquired through use or disuse during its lifetime. "The volume opens with a general statement of the problems of evolution raised by Weismann, and throughout there are scattered some very forcible arguments against the theory of evolution exclusively by the survival of fortuitous favorable variations. The standpoint of the author is with Lamarck and Spencer, that the reactions of the individual to environment is by transmission, the main factor of evolution. We follow the author step by step in his long and very ingenious argument based upon the analogy between mental processes and the slow steps by which living matter gradually acquires its more and more complex characters. As the mind gains ease, frequency and fixation of certain processes by frequent repetition, so in development characters become stable according to the period of time in which they have been performed. Thus the strong 'hereditary impulse' is built up." - George Martin Duncan; book review; Psychological Review, 1894, 1(2), 176–182.
