For not by art does the poet sing, but by power divine. Had he learned by rules of art, he would have known how to speak not of one theme only, but of all; and therefore God takes away the minds of poets, and uses them as his ministers, as he also uses diviners and holy prophets, in order that we who hear them may know them to be speaking not of themselves who utter these priceless words in a state of unconsciousness, but that God himself is the speaker, and that through them he is conversing with us.

The true lover of knowledge naturally strives for truth, and is not content with common opinion, but soars with undimmed and unwearied passion till he grasps the essential nature of things.

The true lover of learning then must his earliest youth, as far as in him lies, desire all truth.... He whose desires are drawn toward knowledge in every form will be absorbed in the pleasures of the soul, and will hardly feel bodily pleasures I mean, if he be a true philosopher and not a sham one ... Then how can he who has the magnificence of mind and is the spectator of all times and all existence, think much of human life He cannot. Or can such a one account death fearful No indeed.

Philosophy is an elegant thing, if anyone modestly meddles with it; but if they are conversant with it more than is becoming, it corrupts them.

As a breath of wind or some echo rebounds from smooth, hard surfaces and returns to the source from which it issued, so the stream of beauty passes back into its possessor through his eyes, which is its natural route to the soul; arriving there and setting him all aflutter, it waters the passages of the feathers and causes the wings to grow, and fills the soul of the loved one in his turn with love.
