As requested by Tarski, this expands on “Ethics of Virtue.” As I alluded to at the end earlier post MacIntyre now considers Aquinas to provide the best account of practical rationality available to us. Part of what he finds compelling about Aquinas is how he is able to integrate two rival systems of thought into one cohesive tradition.
When Aquinas arrived at the University of Paris the faculty was split between those reading and beholden to Augustine and those who were beginning to read and interpret Aristotle, whose works had only recently come to the West via contact with Islamic scholars. A controversy was beginning to develop due to the fact that while Aristotle was consistent and coherent, the conclusions drawn from his work were often at odds with Augustine and Christianity. So, it appeared there were two incompatible and incommensurate systems of thought in rivalry, and it seemed impossible to reconcile these differences.
The most important issues were:
·Aristotle’s ethics were designed for a particular class of Athenian gentlemen. Women, slaves, and ‘barbarians’ weren’t even considered capable of rational judgement. Christianity on the other hand, seeks an ethic for all people.
·Aristotle’s account of the virtues are at times inconsistent with the Christian notion of virtue.
·The Augustine Christian’s notion of the will is utterly foreign to Aristotle.
·The Creator God central to Augustine Christianity is also foreign to Aristotle.
MacIntyre demonstrates how Aquinas is able to address each of these in such as way as to demonstrate the weaknesses in a way comprehensible to the system in need of critique (on its own terms) and to remedy them using the resources of its rival.
MacIntyre sees Aristotle’s account of the telos and the virtues and flawed and incomplete, but when supplemented with Christian notions of humility and grace they are made complete, and available to all people. Aristotle is unable to account for the invariable nature of wrong actions; the Augustinian concept of the will accounts for this. MacIntyre goes on to demonstrate how he believes Aristotle’s philosophy of truth was flawed and in fact required the Augustinian Creator God for completion. On the other hand, MacIntyre sees Augustine’s ethics as unsystematic and prone to generalizations, and the integration of Aristotle’s systematic and carefully considered account of virtue and practical reason is necessary for the comprehension of Augustine’s own account of the virtues.
This is necessarily brief, but it outlines what MacIntyre sees as Aquinas’s crowning achievement in reconciling what appeared to be irreconcilable traditions, and reconciling them in such a way as to show, in terms both could comprehend, how each improved and required the resources of the other.
I’ve drawn on MacIntyre’s Whose Justice? Which Rationality? pgs. 155-208 and Three Rival Versions of Moral Enquiry pgs. 105-126.
