As a lover of truth, the national propaganda of all the belligerent nations sickened me. As a lover of civilization, the return to barbarism appalled me.

I feel life is so small unless it has windows into other worlds.

People who are vigorous and brutal often find war enjoyable.

The trouble with the world is that the stupid are cocksure and the intelligent are full of doubt.

The governors of the world believe, and have always believed, that virtue can only be taught by teaching falsehood, and that any man who knew the truth would be wicked. I disbelieve this, absolutely and entirely. I believe that love of truth is the basis of all real virtue, and that virtues based upon lies can only do harm.

Sir Arthur Eddington deduces religion from the fact that atoms do not obey the laws of mathematics. Sir James Jeans deduces it from the fact that they do.

I suppose the advocates of unreason think that there is a better chance of profitably deceiving the populace if they keep it in a state of effervescence.
