And not only did he learn by experience, but instincts long dead became alive again. The domesticated generations fell from him.

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.

The effect of civilization is to impose human law upon environment until it becomes machine-like in its regularity. The objectionable is eliminated, the inevitable is foreseen.
