(5) I am always dissatisfied with Beauty, which wakes in me a sense of longing exactly the same as the longing of an unreciprocated love. I receive and cannot give. Yet in this beauty and this love there is joy as well as sorrow. (6) My life is part of an organic Whole whose ultimate meaning and purpose is personal relationship--interpenetration. The dissatisfaction is due to a sense of imperfect interpenetration. What is needed, and is felt to be needed, is equal give and take--reciprocal creative activity. Dissatisfaction comes when giving and taking are not balanced. (7) Beauty is eternal, since the creative expression of Love is eternal, and Love knows eternally what it is--is eternally self-conscious. Love is relation, beauty the expression of the immediate knowledge of that relation. (8) This knowledge is always a new, creative act. God must continually express His Being as Love else He would cease to be Love and so to be at all. In Creative Expression He renews Himself. He is for Himself ever new. And, because Love is centrifugal as well as centripetal, He must for ever express Himself _outwards_, so to speak, in the creation of other beings, and this His work of self-abnegation is new and beautiful. (9) We have hardly touched on the problem of the ugly. We have little to add to Croce’s explanation of it as the failure of expression--as the failure to express coherent unity--which involves the failure of intuition. We shall just touch upon it hereafter; at the moment all we need do is to remind ourselves that the ugliest thing in the world is sin, because it is the failure to understand the whole, and to express the fullest, greatest beauty. PART II BEAUTY IN EVOLUTION Theories of aesthetic, so far, have paid little attention to the development of the sense of beauty, except perhaps in the individual. This was natural enough so long as the idea of evolution was unformulated, or, if touched upon speculatively, played little part in men’s general attitude to life; and since the doctrine of evolution came to its own, little original work, beyond that of Croce, has been done in this region. Croce touches the evolutionary aspect but lightly, though it is implicit in his identification of History with Philosophy:
