Mental or spiritual health, which is rationality, makes for progress, and the future demands greater and greater mental or spiritual health, greater and greater rationality. The brain must dominate and direct both the individual and society in the time to come, not the belly and the heart.

Too much is written by the men who can't write about the men who do write.

Stupid women, and all are stupid, think the first winning of the man the final victory. Then they settle down and grow fat, and stale, and dead, and heartbroken. Alas, they are so stupid. But you, little infant-woman with your first victory, you must make your love-life an unending chain of victories. Each day you must win your man again. And when you have won the last victory, when you can find no more to win, then ends love. Finis is written, and your man wanders in strange gardens.

But it did not all happen in a day, this giving over of himself, body and soul, to the man-animals. He could not immediately forego his wild heritage and his memories of the Wild. There were days when he crept to the edge of the forest and stood and listened to something calling him far and away.

There are, broadly speaking, two types of drinkers. There is the man whom we all know, stupid, unimaginative, whose brain is bitten numbly by numb maggots; who walks generously with wide-spread, tentative legs, falls frequently in the gutter, and who sees, in the extremity of his ecstasy, blue mice and pink elephants.... The other type of drinker has imagination, vision. Even when most pleasantly jingled he walks straight and naturally, never staggers nor falls, and knows just where he is and what he is doing. It is not his body but his brain that is drunken.
