Yes, he said, he is the only one remaining.
There is, however, I said, a previous question which remains unanswered.
What question?
I do not think that we have adequately determined the nature and number of the appetites, and until this is accomplished the enquiry will always be confused.
Well, he said, it is not too late to supply the omission.
Very true, I said; and observe the point which I want to understand: Certain of the unnecessary pleasures and appetites I conceive to be unlawful; every one appears to have them, but in some persons they are controlled by the laws and by reason, and the better desires prevail over them-either they are wholly banished or they become few and weak; while in the case of others they are stronger, and there are more of them.
Which appetites do you mean?
I mean those which are awake when the reasoning and human and ruling power is asleep; then the wild beast within us, gorged with meat or drink, starts up and having shaken off sleep, goes forth to satisfy his desires; and there is no conceivable folly or crime—not excepting incest or any other unnatural union, or parricide, or the eating of forbidden food—which at such a time, when he has parted company with all shame and sense, a man may not be ready to commit.
Most true, he said.
But when a man's pulse is healthy and temperate, and when before going to sleep he has awakened his rational powers, and fed them on noble thoughts and enquiries, collecting himself in meditation; after having first indulged his appetites neither too much nor too little, but just enough to lay them to sleep, and prevent them and their enjoyments and pains from interfering with the higher principle—which he leaves in the solitude of pure abstraction, free to contemplate and aspire to the knowledge of the unknown, whether in past, present, or future: when again he has allayed the passionate element, if he has a quarrel against any one—I say, when, after pacifying the two irrational principles, he rouses up the third, which is reason, before he takes his rest, then, as you know, he attains truth most nearly, and is least likely to be the sport of fantastic and lawless visions.
