We, by our arts may be called the grandsons of God.

Now do you not see that the eye embraces the beauty of the whole world? It counsels and corrects all the arts of mankind... it is the prince of mathematics, and the sciences founded on it are absolutely certain. It has measured the distances and sizes of the stars it has discovered the elements and their location... it has given birth to architecture and to perspective and to the divine art of painting.

Especially learn how to see.

He who is fixed to a star does not change his mind.

When counting, try not to mix chickens with blessings.
