Abstract
Psychological egoism is, I suppose, regarded by most philosophers as one of the more simple-minded fallacies in the history of philosophy, and dangerous and seductive too, contriving as it does to combine cynicism about human ideals and a vague sense of scientific method, both of which make the ordinary reader feel sophisticated, with conceptual confusion, which he cannot resist. For all of these reasons it springs eternal, in one form or another, in the breasts of first-year students, and offers excellent material for their philosophy instructors, who like nothing better than an edifice of sturdy appearance but with rotten foundations on which to display their skill as demolition experts
