Love is a madness produced by an unsatisfiable rational desire to understand the ultimate truth about the world.

A man is not learned until he can read, write and swim.

What essence is to generation, that truth is to belief.

The Earth is like one of those balls made of twelve pieces of skin.

The beginning is half of the whole.

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.

Everything changes and nothing remains still.
