War is not the best way of settling differences; it is the only way of preventing their being settled for you.

There are arguments for atheism, and they do not depend, and never did depend, upon science. They are arguable enough, as far as they go, upon a general survey of life; only it happens to be a superficial survey of life.

A man will not roll in the snow for a stream of tendency by which all things fulfill the law of their being. He will not go without food in the name of something, not ourselves, that makes for righteousness. He will do things like this, or pretty nearly like this, under quite a different impulse. He will do these things when he is in love.

Theology is only thought applied to religion.

Sir Hiram Maxim is a genuine and typical example of the man of science, romantic, excitable, full of real but somewhat obvious poetry, a little hazy in logic and philosophy, but full of hearty enthusiasm and an honorable simplicity. He is, as he expresses it, "an old and trained engineer," and is like all of the old and trained engineers I have happened to come across, a man who indemnifies himself for the superhuman or inhuman concentration required for physical science by a vague and dangerous romanticism about everything else.

I still think sincere pessimism the unpardonable sin.
