Being is desirable because it is identical with Beauty, and Beauty is loved because it is Being. We ourselves possess Beauty when we are true to our own being; ugliness is in going over to another order; knowing ourselves, we are beautiful; in self-ignorance, we are ugly.
PlotinusBeauty addresses itself chiefly to sight, but there is a beauty for the hearing too, as in certain combinations so words and in all kinds of music; for melodies and cadences are beautiful; and minds that lift themselves above the realm of sense to a higher order are aware of beauty in the conduct of life, in actions, in character, in the pursuits of the intellect; and there is the beauty of the virtues.
Plotinus
