Simplicity is the greatest adornment of art.

Love and delight are better teachers than compulsion.

I hold that the perfection of form and beauty is contained in the sum of all men.

Nature holds the beautiful, for the artist who has the insight to extract it. Thus, beauty lies even in humble, perhaps ugly things, and the ideal, which bypasses or improves on nature, may not be truly beautiful in the end.

And since geometry is the right foundation of all painting, I have decided to teach its rudiments and principles to all youngsters eager for art. . .

No single man can be taken as a model for a perfect figure, for no man lives on earth who is endowed with the whole of beauty.

Sight is the noblest sense of man.
