 Everything capable of being represented to the senses as a perfection could also present an object of beauty. Belonging here are all the perfections of external forms, that is, the lines, surfaces, and bodies and their movements and changes; the harmony of the multiple sounds and colors; the order in the parts of a whole, their similarity, variety, and harmony; their transposition and transformation into other forms; all the capabilities of our soul, all the skills of our body. Even the perfections of our external state (under which honor, comfort, and riches are to be understood) cannot be excepted from this if they are fit to be represented in a way that is apparent to the senses.
