And, ere I begin, I must ask the reader to walk with me in all sympathy; and, since sympathy is merely understanding, begin by understanding me and whom and what I write about. In the first place, I am a seasoned drinker. I have no constitutional predisposition for alcohol. I am not stupid. I am not a swine. I know the drinking game from A to Z, and I have used my judgment in drinking. I never have to be put to bed. Nor do I stagger. In short, I am a normal, average man; and I drink in the normal, average way, as drinking goes. And this is the very point: I am writing of the effects of alcohol on the normal, average man. I have no word to say for or about the microscopically unimportant excessivist, the dipsomaniac.

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. He is the type that gives rise to the jokes in the funny papers.

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. He may bubble with wit, or expand with good fellowship. Or he may see intellectual spectres and phantoms that are cosmic and logical and that take the forms of syllogisms. It is when in this condition that he strips away the husks of life's healthiest illusions and gravely considers the iron collar of necessity welded about the neck of his soul.
