The many contradictions among different philosophical theories have caused much confusion over the years. Unfortunately, too few teachers and textbooks explain the basic principles that could help students discriminate
intelligently among them and understand the ethical code which fosters freedom, morality and social cooperation. Thus, Henry Hazlitt deserves special credit for bringing logic and clarity to the subject. His book, The Foundations of Morality, was first published in 1964. After having been out of print for several years, it is again available thanks to Nash and the Institute for Humane Studies.
