Jaffa, Harry. Thomism and Aristotleanism: A Study of the Commentary by Thomas Aquinus on the Nicomachean Ethics, New York: Praeger Press, 1979 reprint.
Dubbed a “minor classic” by Alasdair MacIntyre, Jaffa’s Thomism and Aristotelianism, that grew out of his doctoral dissertation, analyzes Thomas’ interpretation of Aristotle’s Nicomachean Ethics. The problem to be examined is how Aristotle’s “pagan” ethics might be interpreted in a non-pagan, indeed Christian, context. While Jaffa highlights the immense influence of Aristotle on Thomas, he also points to ways in which Thomas departed from Aristotle.
