When, in the present world, men behave well, that is no doubt sometimes because they are creatures of habit as well as, sometimes, because they are reasonable.

An abundance of some good things is perfectly compatible with the scarcity of others; that life is everywhere precarious, man everywhere small.

Being the inventor of sex would seem to be a sufficient distinction for a creature just barely large enough to be seen by the naked eye.

Though we face the facts of sex we are more reluctant than ever to face the fact of death or the crueler facts of life, either biological or social.

It is not a sentimental, but a grimly literal fact that unless we share this terrestrial globe with creatures other than ourselves, we shall not be able to live on it for long.

Perhaps we are wiser, less foolish and more far-seeing than we were two hundred years ago. But we are still imperfect in all these things, and since the turn of the century it has been remarked that neither wisdom nor virtue have increased as rapidly as the need for both.

It is not ignorance but knowledge which is the mother of wonder.
