Life without sex might be safer but it would be unbearably dull. It is the sex instinct which makes women seem beautiful, which they are once in a blue moon, and men seem wise and brave, which they never are at all. Throttle it, denaturalize it, take it away, and human existence would be reduced to the prosaic, laborious, boresome, imbecile level of life in an anthill.

Every step in human progress, from the first feeble stirrings in the abyss of time, has been opposed by the great majority of men. Every valuable thing that has been added to the store of man's possessions has been derided by them when it was new, and destroyed by them when they had the power. They have fought every new truth ever heard of, and they have killed every truth-seeker who got into their hands.

We suffer most when the White House busts with ideas.

Two simple principles lie at the bottom of the whole matter, and they may be precipitated into two rules. The first is that, when there is a choice, the milder drink is always the better-not merely the safer but the better. The second is that no really enlightened drinker ever takes a drink at a time when he has any work to do. There is, of course, more to it than this; but these are sufficient for the beginner, and even the virtuoso never outgrows them.

The believing mind is externally impervious to evidence. The most that can be accomplished with it is to induce it to substitute one delusion for another. It rejects all overt evidence as wicked.

It is the dull man who is always sure, and the sure man who is always dull.

The human race is divided into two sharply differentiated and mutually antagonistic classes: a smal l minority that plays with ideas and is capable of taking them in, and a vast majority that finds them painful, and is thus arrayed against them, and against all who have traffic with them.
