The one genuinely dangerous and immoral way of drinking alcohol is to drink it as a medicine. And for this reason. If a man drinks wine in order to obtain pleasure, he is trying to obtain something exceptional, something he does not expect every hour of the day, something which, unless he is a little insane, he will not try to get every hour of the day. But if a man drinks wine in order to obtain health, he is trying to get something natural; something, that is, that he ought not to be without; something that he may find it difficult to reconcile himself to being without. Hence comes the fact which every doctor knows, that it is often perilous to give alcohol to the sick even when they need it. I need hardly say that I do not mean that I think the giving of alcohol to the sick for stimulus is necessarily unjustifiable. But I do mean that giving it to the healthy for fun is the proper use of it, and a great deal more consistent with health.
The sound rule in the matter would appear to be like many other sound rules—a paradox. Drink because you are happy, but never because you are miserable. Never drink when you are wretched without it, or you will be like the grey-faced gin-drinker in the slum; but drink when you would be happy without it, and you will be like the laughing peasant of Italy. Never drink because you need it, for this is rational drinking, and the way to death and hell. But drink because you do not need it, for this is irrational drinking, and the ancient health of the world.
