There is only one good, knowledge, and one evil, ignorance.

The greatest enemy of knowledge is not ignorance, it is the illusion of knowledge.

Imagination is more important than knowledge. Knowledge is limited. Imagination encircles the world.

Art is never finished, only abandoned.

My brain is only a receiver, in the Universe there is a core from which we obtain knowledge, strength and inspiration. I have not penetrated into the secrets of this core, but I know that it exists.

Realize that everything connects to everything else.

I have been impressed with the urgency of doing. Knowing is not enough, we must apply. Being willing is not enough, we must do.

The noblest pleasure is the joy of understanding.

Why does the eye see a thing more clearly in dreams than the imagination when awake?
