I really have a lot of stuff in my head; if only there were insurance companies for that as there are for so many things.

Drawing is not what you see but what you must make others see.

Drawing is the artist's most direct and spontaneous expression, a species of writing: it reveals, better than does painting, his true personality.

Work a great deal at evening effects, lamplight, candlelight, etc. The intriguing thing is not to show the source of the light but the effect of the lighting.

If I could have had my own way, I would have confined myself to black and white.

It is all very well to copy what one sees, but it is far better to draw what one now only sees in one's memory. That is a transformation in which imagination collaborates with memory.

The fascinating thing, is not to show the source of light, but the effect of light.
