[4] The classic discussion of the whole matter is to be found in Aristotle's Nicomachean Ethics, Book I, Chapters I-VI, translated by J. E. C. Welldon. Cf. also Fr. Paulsen: System of Ethics, Book II, Chapters I, II, translated by Frank Thilly; G. H. Palmer: The Nature of Goodness, Chapters I, II; and W. James: The Moral Philosopher and the Moral Life, in his Will to Believe.
[5] The issue is presented clearly and briefly in Paulsen: Op. cit., Book II, Chapter II, and in James's Principles of Psychology, Vol. II, pp. 549-559.
