Painting is with me but another word for feeling.

There has never been a boy painter, nor can there be. The art requires a long apprenticeship, being mechanical, as well as intellectual.

It will be difficult to name a class of landscape in which the sky is not the key note, the standard of scale, and the chief organ of sentiment.

A sketch will not serve more than one state of mind & will not serve to drink at again & again — in a sketch there is nothing but the one state of mind — that which you were in at the time.

I never saw an ugly thing in my life.

I do not consider myself at work unless I am before a six-foot canvas.

I never saw an ugly thing in my life: for let the form of an object be what it may - light, shade, and perspective will always make it beautiful.
