An artist reveals his naked soul in his work.

An emotion as much tells you nothing about reality, beyond the fact that something makes you feel something.

You'd let the whole world perish rather than soil that immaculate self of yours with a single spot of which you'd have to be ashamed.

I like to receive money for my work. But I can pass that up this time. I like to have people know my work is done by me. But I can pass that up. I like to have tenants made happy by my work. But that doesn't matter too much. The only thing that matters, my goal, my reward, my beginning, my end is the work itself. My work done my way. Peter, there's nothing in the world that you can offer me, except this. Offer me this and you can have anything I've got to give. My work done my way. A private, personal, selfish, egotistical motivation. That's the only way I function. That's all I am.

One must differentiate between one's thoughts and one's emotions with full clarity and precision...No discussion, cooperation, agreement, or understanding is possible among men who substitute emotion for proof.

You have been the one encounter in my life that can never be repeated

Science was born as a result and consequence of philosophy; it cannot survive without a philosophical base. If philosophy perishes, science will be next to go.
