The idea of a personal God is an anthropological concept which I am unable to take seriously.

I am an absolute pacifist...It is an instinctive feeling. It is a feeling that possesses me, because the murder of men is disgusting.

A conviction akin to religious feeling of the rationality or intelligibility of the world lies behind all scientific work of a high order.

Not until we dare to regard ourselves as a nation, not until we respect ourselves, can we gain the esteem of others, or rather only then will it come of its own accord

To raise new questions, new possibilities, to regard old problems from a new angle, requires creative imagination and marks real advance in science.

I have no special talent. I am only passionately curious.

More the knowledge lesser the Ego, lesser the knowledge, more the Ego.
