I have always disliked the fierce competitive spirit embodied in that highly intellectual game.

Nothing will end war unless the peoples themselves refuse to go to war.

The man of science is a poor philosopher.

My interest in science was always essentially limited to the study of principles.... That I have published so little is due to this same circumstance, as the great need to grasp principles has caused me to spend most of my time on fruitless pursuits.

I make it a rule not to clutter my mind with simple information that I can find in a book in five minutes.

You are the only person I know who has the same attitude towards physics as I have: belief in the comprehension of reality through something basically simple and unified... It seems hard to sneak a look at God's cards. But that He plays dice and uses 'telepathic' methods... is something that I cannot believe for a single moment.

Small is the number of them that see with their own eyes and feel with their own hearts.
