Art teaches you the philosophy of life, and if you can't learn it from art, you can't learn it at all. It shows you that there is no perfection. There is light, and there is shadow. Everything is in half tint.
Painting is the only universal language. All nature is creation's picture book. Painting alone can describe every thing which can be seen, and suggest every emotion which can be felt. Art reaches back into the babyhood of time, and is man's only lasting monument.
The mission of art is to represent nature not to imitate her.
