The bearing of certain psychological doctrines upon ethical theory is important, and has been made use of especially by those who espouse empiricism in Ethics. It is the purpose of this paper to examine some of these leading doctrines and the ethical theory which has been connected with them. In doing so, it is appropriate to select for examination the views of Professor W. McDougall, as expressed principally in his Social Psychology and Outline of Psychology ; and this for two (...) reasons. One is, that these views are significant of much more than the opinions of one man. They may be taken quite fairly as representative, in the main, of a definite body of doctrine concerning the nature and development of moral experience. (shrink)
