Again, it may be said that such moments too seldom occur in any man’s experience to justify even the most modest generalisations—let alone generalisations that embrace the universe. But this objection seems to rest on a misapprehension. We must remember that the argument from æsthetic values is not a scientific induction or a logical inference. There is here no question of truth and falsehood, or even of good taste and bad taste. We are not striving to isolate what is essential to beauty by well-devised experiments; nor are we concerned with psycho-physical determination of the normal relation between feeling and stimulus. If it be urged that some particular example of deep æsthetic emotion quite outruns the merits of its object, so that sound canons of criticism require its value to be lowered, we need not deny it. We are not dealing with sound canons of criticism; though I may observe, in passing, that if they lower emotional values in one direction without raising them in others, good taste becomes a somewhat costly luxury. My point is different. I am not appealing to all men, but only to some men—to those and to those only who, when they explicitly face the problem, become deeply conscious of the incongruity between our feelings of beauty and a materialistic account of their origin. The extreme individualism of this point of view may seem repulsive to many. Are the feelings (they will ask) of some transient moment to be treated as authentic guides through the mysteries of the universe, merely because they are strong enough to overwhelm our cooler judgment? And, if so, how far is this method of metaphysical investigation to be pressed? Are we, for example, to attach transcendental value to the feelings of a man in love? There is evidently a close, though doubtless not a perfect, parallel between the two cases. It is true that love is rooted in appetite, and that appetite has a survival value which I, at least, cannot find in the purely contemplative emotions. But romantic love goes far beyond race requirements. From this point of view it is as useless as æsthetic emotion itself. And, like æsthetic emotion of the profounder sort, it is rarely satisfied with the definite, the limited, and the immediate. It ever reaches out towards an unrealised infinity. It cannot rest content with the prose of mere fact. It sees visions and dreams dreams which to an unsympathetic world seem no better than amiable follies. Is it from sources like these—the illusions of love and the enthusiasms of ignorance—that we propose to supplement the world-outlook provided for us by sober sense and scientific observation? Yet why not? Here we have values which by supposition we are reluctant to lose. Neither scientific observation nor sober sense can preserve them. It is surely permissible to ask what will. And if Naturalism be inimical to their maintenance, the fact should at least be noted.
