since in the former case it would appear as though he had still had
the choice (for which he would then require another virtue, in order
to select virtue from all other wares offered to him). To conceive a

conceive various moral objects to which the (rational) will is led
by the single principle of virtue; and it is the same with the
opposite vices. The expression which personifies both is a contrivance
for affecting the sensibility, pointing, however, to a moral sense.
Hence it follows that an aesthetic of morals is not a part, but a
subjective exposition of the Metaphysic of Morals; in which the
emotions that accompany the force of the moral law make the that force
to be felt; for example: disgust, horror, etc., which gives a sensible
moral aversion in order to gain the precedence from the merely
sensible incitement.
