If human beings could be propagated by cutting, like apple trees, aristocracy would be biologically sound.

Einstein - the greatest Jew since Jesus. I have no doubt that Einstein's name will still be remembered and revered when Lloyd George, Foch and William Hohenzollern share with Charlie Chaplin that ineluctable oblivion which awaits the uncreative mind.

A fairly bright boy is far more intelligent and far better company than the average adult.

I have never yet met a healthy person who worried very much about his health, or a really good person who worried much about his own soul.

So many new ideas are at first strange and horrible, though ultimately valuable that a very heavy responsibility rests upon those who would prevent their dissemination.

To the biologist the problem of socialism appears largely as a problem of size. The extreme socialists desire to run every nation as a single business concern. I do not suppose that Henry Ford would find much difficulty in running Andorra or Luxembourg on a socialistic basis. He has already more men on his pay-roll than their population. It is conceivable that a syndicate of Fords, if we could find them, would make Belgium Ltd. or Denmark Inc. pay their way. But while nationalization of certain industries is an obvious possibility in the largest of states, I find it no easier to picture a completely socialized British Empire or United States than an elephant turning somersaults or a hippopotamus jumping a hedge.
