Remarkable for its moderation and common sense. . . . [McInerny] rapidly sketches selected themes from Thomistic moral thinking: what distinguishes the moral activities of man, what is distinctive of moral goodness (in Aristotle and in Aquinas), an analysis of practical reason in relation to natural law, the bases for judging good and evil moral actions, the roles of intellect and will in voluntary activity, the work of virtues as components of moral character, the functions of prudence and conscience, and finally the relation of ethics to religious belief. . . . For the person who desires a quick and understandable introduction to this subject, this little book can be recommended as readable and reliable."-Vernon J. Bourke, Speculum "An important contribution both to moral philosophy and to its teaching. . . . [McInerny] has put us all in his debt by writing it."-Alasdair MacIntyre, Teaching Philosophy "A clear, thorough and readable introduction to the thought of one of the intellectual giants of the Catholic moral tradition."-National Catholic Register
