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

Before me, even as behind, God is, and all is well.

Every good picture leaves the painter eager to start again, unsatisfied, inspired by the rich mine in which he is working, hoping for more energy, more vitality, more time - condemned to painting for life.

I know my flaws before other people point them out to me.

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

The landscape painter must walk in the fields with a humble mind. No arrogant man was ever permitted to see Nature in all her beauty.
