Abstract

Autonomy was an important political concept in ancient Greece. Kant made it the ground of morality: only acting motivated by autonomous reason is moral. But he admits that reason does not have a power to motivate us: desires can always override it. Thus it seems that human reason is not autonomous. The principle of autonomy, however, is an intrinsic part of Kant’s “Copernican Revolution” and his rationalism about the grounding of morality. Questioning the former would lead to fideism or to skepticism while rejecting the latter to reductionism. Neither course is less problematic for grounding morality than the principle of autonomy is. I suggest that Aristotle can help us to see how this dilemma can be avoided. Unlike Kant and many others, he does not seek to ground morality beyond our experience. The Aristotelian understanding of human beings as capable of evaluating one another’s actions with the language of purposefulness can explain which actions are moral without falling into the dilemma implied by the Kantian principle of autonomy.
