Aristotle Metaphysics Reversed

Listening to Book Eight, particularly Aristotle's distinction between potentiality and capability, two terms whose clear differences still escape me, I am struck by Alasdair MacIntyre's argument in After Virtue that the Post-Structuralist critique of Western Thought is actually a critique of Medieval interpretations of the Greeks, not the Greeks themselves. As I read Aristotle, it appears to me that he is making an effort to develop a metaphysics that is explanatory, that actually tells us what the sensory and virtual worlds are like. Later, Scholasticism reverses that polarity. Instead of using what we know to explain what we don't know, they use what we don't know, in this case, the divine, to explain what we do know. Thus, in their interpretation of Aristotle, the sensory and virtual world must be arranged to "fit" the metaphysical.
