What then is desire in Man? Here we come back again, as suggested at the outset, to Man himself. Though we see pretty clearly that desire is at work in the animals, and that it is the same in kind as exists in man, still, among the animals it is but dim and inchoate, while in man it is developed and luminous; in ourselves, too, we know it immediately, while in the animals only by inference. For both reasons, therefore, if we want to know the nature of desire--even to know its nature among animals--we should study it in Man. What then is this desire in Man, which seems to be the instigation and origin of all his growth and development? At first it seems a hydra-headed senseless thing without rhyme or reason; but the more one regards it the more clearly one sees that even in its lowest forms it is steadily building up and liberating all the functions of the human being. In its most perfect form--as in what we call Love--it is the sum and solution of human activities, that in which they converge, for which they all exist, and without which they would be considered useless. The more you look into this matter, the plainer it becomes. The lesser desires--the self-preservation desires--hunger, thirst, the desire of power--exist, but when they are satisfied they empty themselves into this one; they find their interpretation in it. The other desires are nothing by themselves--the most absorbing, avarice, ambition, desire of knowledge, taken alone, stultify themselves--but love perpetuates itself; it is a flame which uses all the rest as its fuel. And this Love, which is the culmination of desire, does it not appear to us as a worship of and desire for the human form? In our bodies a desire for the bodily human form; in our interior selves a perception and worship of an ideal human form, the revelation of a Splendour dwelling in others, which--clouded and dimmed as it inevitably may come to be--remains after all one of the most real, perhaps the most real, of the facts of existence? Desire, therefore--as it exists in man, look at it how you will--as it unfolds and its ultimate aim becomes clearer and clearer to itself, is seen to be the desire and longing for the deliverance and expression of the real human Being. May it not, must it not, be the same thing in animals and all through creation? Beginning in the most elementary and dim shapes, does it not grow through all the stages of organic life clearer and more and more powerful, till at last it attains to self-consciousness in humanity and becomes avowedly the leading factor in our development?
