From Man Ray

"To me, a painter, if not the most useful, is the least harmful member of our society."

From Edmond de Goncourt

"A painting in a museum hears more ridiculous opinions than anything else in the world."

From William Hazlitt:

"One is never tired of painting, because you have to set down, not what you already knew, but what you have just discovered."

From Pablo Picasso:

"It took me a lifetime to learn to paint like a child."

From Edgar Degas:

"Painting is easy when you don't know how, but very difficult when you do."
