 But Aristotle’s agreement with Socrates is only partial, because he insists on the power of the emotions to rival, weaken or bypass reason. Emotion challenges reason in all three of these ways. In both the akratic and the enkratic, it competes with reason for control over action; even when reason wins, it faces the difficult task of having to struggle with an internal rival. Second, in the akratic, it temporarily robs reason of its full acuity, thus handicapping it as a competitor. It is not merely a rival force, in these cases; it is a force that keeps reason from fully exercising its power. And third, passion can make someone impetuous; here its victory over reason is so powerful that the latter does not even enter into the arena of conscious reflection until it is too late to influence action.
