That alcohol in dilute aqueous solution, when taken into the human organism, acts as a depressant, not a stimulant, is now so much a commonplace of knowledge that even the more advanced varieties of physiologists are beginning to be aware of it. The intelligent layman no longer resorts to the jug when he has important business before him, whether intellectual or manual; he resorts to it after his business is done, and he desires to release his taut nerves and reduce the steam-pressure in his spleen. Alcohol, so to speak, unwinds us. It raises the threshold of sensation and makes us less sensitive to external stimuli, and particularly to those that are unpleasant. Putting a brake upon all the qualities which enable us to get on in the world and shine before our fellows – for example, combativeness, shrewdness, diligence, ambition-, it releases the qualities which mellow us and make our fellows love us – for example, amiability, generosity, toleration, humor, sympathy. A man who has taken aboard two or three cocktails is less competent than he was before to steer a battleship down the Ambrose Channel, or to cut off a leg, or to draw up a deed of trust, or to conduct Bach’s B minor mass, but he is immensely more competent to entertain a dinner party, to admire a pretty girl, or to hear Bach’s B minor mass. The harsh, useful things of the world, from pulling teeth to digging potatoes, are best done by men who are as starkly sober as so many convicts in the death-house, but the lovely and useless things, the charming and exhilarating things, are best done by men with, as the phrase is, a few sheets in the wind. Pithecanthropus erectus was a teetotaler, but the angels, you may be sure, know what is proper at 5 p.m.
