All my indispositions have their source in my mind. It is when I am restless and unhappy that I become susceptible of cold, damp, heats, and such nonsense.

My art flatters nobody by imitation; it courts nobody by smoothness, tickles nobody by petiteness... there is no finish in nature.

Landscape is my mistress - 'tis to her I look for fame.

I know dock leaves pretty well, but I should not attempt to introduce them into a picture without having them before me.

Whatever may be thought of my art, it is my own; and I would rather possess a freehold, though but a cottage, than live in a palace belonging to another.

Nature is the fountain's head, the source from whence all originality must spring.

Painting is a science, and should be pursued as an inquiry into the laws of nature.

The sound of water escaping from mill dams, etc., willows, old rotten planks, slimy posts, and brickwork, I love such things.

Painting is but another word for feeling.

The sky is the source of light in nature - and governs everything.
