 To begin with, the analogy concerns their structure or unity. Both have holistic unities, where the parts and the whole are reciprocally interdependent. Artworks and natural beauties are so structured since (1) their beauty as a whole depends on the existence and the exact organization of their parts (for, if, say, any of the specific shapes, hues, or composition of a painting were to change, the painting as a whole may not be beautiful any longer), and (2) their parts are recognized as what they are (as beauty-making parts, or parts of a beautiful object) only in light of the whole (so that, for example, a mere shade of white may be beautiful only in light of the beauty of the painting to which it contributes as a whole, but not necessarily beautiful on its own, or when it figures in any other object). “In poetry”, then, just as in organisms, “every whole can be a part and every part really a whole” (F. Schlegel, CF: #14).
