The painter must enclose himself within his work; he must respond not with words, but with paintings.

There is a logic of colors, and it is with this alone, and not with the logic of the brain, that the painter should conform.

Don't be an art critic. Paint. There lies salvation.

I must be more sensible and realize that at my age, illusions are hardly permitted and they will always destroy me.

If I think, everything is lost.

Art first of all is optical. That's where the material of our art is: in what our eyes think.
