Why does the eye see a thing more clearly in dreams than the imagination when awake?

There is no object so large but that at a great distance from the eye it does not appear smaller than a smaller object near.

The painter who draws merely by practice and by eye, without any reason, is like a mirror which copies every thing placed in front of it without being conscious of their existence.

Where the spirit does not work with the hand, there is no art.

Poor is the pupil who does not surpass his master.

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