  First, Kant evidently holds that objects of aesthetic experience can present morally significant ideas to us without sacrificing what is essential to them as objects of aesthetic response and judgment.  This is obvious in the theory of aesthetic ideas, where Kant indeed assumes that works of art always have some morally relevant content. But this view takes other forms as well. In fact, Kant maintains that all forms of beauty, natural as well as artistic, can be regarded as expressions of aesthetic ideas: even natural objects can suggest moral ideas to us although such suggestion is not the product of any intentional human activity (CPJ, §51, 5:319). In “The Ideal of Beauty,” Kant also maintains that beauty in the human figure can be taken as “the visible expression of moral ideas, which inwardly govern human beings”; here he argues that only human beauty can be taken as a unique standard for beauty, because it is the only form of beauty that can express something absolutely and unconditionally valuable, namely the moral autonomy of which humans alone are capable. At the same time he holds there is no determinate way in which this unique value can be expressed in the human form, thus there is always something free in the outward expression in the human figure of the inner moral value of the human character (CPJ, §17, 5:235–6).
