I cannot divide them into clearly defined classes, but I may perhaps begin with those that bring one into the widest sympathy with living things and go on to those one shares only with highly intelligent and complex human beings.

There come first the desires one shares with those more limited souls the beasts, just as much as one does with one’s fellow man. These are the bodily appetites and the crude emotions of fear and resentment. These first clamour for attention and must be assuaged or controlled before the other sets come into play.

Now in this matter of physical appetites I do not know whether to describe myself as a sensualist or an ascetic. If an ascetic is one who suppresses to a minimum all deference to these impulses, then certainly I am not an ascetic; if a sensualist is one who gives himself to heedless gratification, then certainly I am not a sensualist. But I find myself balanced in an intermediate position by something that I will speak of as the sense of Beauty. This sense of Beauty is something in me which demands not simply gratification but the best and keenest of a sense or continuance of sense impressions, and which refuses coarse quantitative assuagements. It ranges all over the senses, and just as I refuse to wholly cut off any of my motives, so do I refuse to limit its use to the plane of the eye or the ear.

It seems to me entirely just to speak of beauty in matters of scent and taste, to talk not only of beautiful skies and beautiful sounds but of beautiful beer and beautiful cheese! The balance as between asceticism and sensuality comes in, it seems to me, if we remember that to drink well one must not have drunken for some time, that to see well one’s eye must be clear, that to make love well one must be fit and gracious and sweet and disciplined from top to toe, that the finest sense of all — the joyous sense of bodily well-being — comes only with exercises and restraints and fine living. There I think lies the way of my disposition. I do not want to live in the sensual sty, but I also do not want to scratch in the tub of Diogenes.

But I diverge a little in these comments from my present business of classifying motives.

Next I perceive hypertrophied in myself and many sympathetic human beings a passion that many animals certainly possess, the beautiful and fearless cousin of fear, Curiosity, that seeks keenly for knowing and feeling. Apart from appetites and bodily desires and blind impulses, I want most urgently to know and feel, for the sake of knowing and feeling. I want to go round corners and see what is there, to cross mountain ranges, to open boxes and parcels. Young animals at least have that disposition too. For me it is something that mingles with all my desires. Much more to me than the desire to live is the desire to taste life. I am not happy until I have done and felt things. I want to get as near as I can to the thrill of a dog going into a fight or the delight of a bird in the air. And not simply in the heroic field of war and the air do I want to understand. I want to know something of the jolly wholesome satisfaction that a hungry pig must find in its wash. I want to get ............
