 Kant, as discussed above, underwent a decisive change of mind about the views of Shaftesbury, Hutcheson, and Hume. Early in his career, he endorsed core aspects of their approach, but Kant’s mature work is organized around the idea that reason, rather than feeling or emotion, is the highest authority in the moral domain. In this respect, many features of his moral philosophy are fundamentally opposed to Hume’s. We can see this opposition in their respective accounts of moral judgment and moral motivation. A careful look at these topics, however, also highlights sentimentalism’s residual influence on Kant.
