WHAT IS THE PRINCIPLE BY PARTICIPATION IN WHICH THE BODY IS BEAUTIFUL?
First, there are certain objects, such as bodies, whose beauty exists only by participation, instead of being inherent in the very essence of the subject. Such are beautiful in themselves, as is, for example, virtue. Indeed, the same bodies seem beautiful at one time, while at another they lack beauty; consequently, there is a great difference between being a body and being beautiful. What then is the principle whose presence in a body produces beauty therein? What is that element in the bodies which moves the spectator, and which attracts, fixes and charms his glances? This is the first problem to solve; for, on finding this principle, we shall use it as a means to resolve other questions.
