A human being is part of a whole, called by us the 'Universe,' a part limited in time and space. He experiences himself, his thoughts and feelings, as something separated from the rest--a kind of optical delusion of his consciousness.

Our task must be to free ourselves from this prison by widening our circles of compassion to embrace all living creatures and the whole of nature in its beauty.

If we knew what we were doing, it wouldn't be called research, would it?

It is a miracle that curiosity survives formal education.

If I have seen farther than others, it is because I was standing on the shoulders of giants.

I don't know with what weapons World War III will be fought, but World War IV will be fought with sticks and stones.

The release of atom power has changed everything except our way of thinking...the solution to this problem lies in the heart of mankind. If only I had known, I should have become a watchmaker.

Reality is merely an illusion, albeit a very persistent one.

Not everything that can be counted counts, and not everything that counts can be counted.
