Two Christian-Aristotelian Ethics: The Ethics of Aquinas and Augustine vs. the Situation Ethics of Joseph Fletcher

Abstract

First, we shall examine theoretical similarities and differences between two ethics: that of a Christian-Aristotelian Ethics as commented upon by Aquinas and Augustine and that of a Christian-Aristotelian Ethics as developed by Joseph Fletcher in his Situation Ethics. The deep similarity is that both ethics find that the highest virtue is that of love. The key difference is that for a Christian-Aristotelian Ethics developed by Aquinas and Augustine there are some actions and feelings that are evil in themselves and which have no Golden Mean whereas for a Christian-Aristotelian Ethics as developed by Fletcher there are no actions which are evil in themselves. This question of whether there are actions evil in themselves is the primary reason for writing this paper. Second, we shall examine (a) the positive practice of the virtues, arguing that there is little to no practical difference between a Christian-Aristotelian ethics as developed by Aquinas and Augustine and a Christian-Aristotelian situation ethics as developed by Fletcher in the positive practice of the virtues; and we shall examine (b) the practical differences between these two ethics in deciding whether there are some actions that are evil in themselves by reflecting upon the four conditions of the principle of the double effect. The paper will conclude by favoring a Christian-Aristotelian Ethics as developed by Aquinas and Augustine. Keywords: Christian-Aristotelian Ethics, Aquinas, Augustine, Joseph Fletcher
