It is easy to explain why the satisfaction in the pure aesthetical judgement in the case of beautiful Art is not combined with an immediate interest as it is in the case of beautiful Nature. For the former is either such an imitation of the latter that it reaches the point of deception and then produces the same effect as natural beauty (for which it is taken); or it is an art obviously directed designedly to our satisfaction. In the latter case the satisfaction in the product would, it is true, be brought about immediately by taste, but it would be only a mediate interest in the cause lying at its root, viz. an art that can only interest by means of its purpose and never in itself. It will, perhaps, be said that this is also the case, if an Object of nature interests us by its beauty only so far as it is associated with a moral Idea. But it is not the Object itself which immediately interests us, but its character in virtue of which it is qualified for such association, which therefore essentially belongs to it.
The charms in beautiful Nature, which are so often found, as it were, blended with beautiful forms, may be referred to modifications either of light (colours) or of sound (tones). For these are the only sensations that imply not merely a sensible feeling but also reflection upon the form of these modifications of Sense; and thus they involve in themselves as it were a language by which nature speaks to us, which thus seems to have a higher sense. Thus the white colour of lilies seems to determine the mind to Ideas of innocence; and the seven colours in order from the red to the violet seem to suggest the Ideas of (1) Sublimity, (2) Intrepidity, (3) Candour, (4) Friendliness, (5) Modesty, (6) Constancy, (7) Tenderness. The song of birds proclaims gladsomeness and contentment with existence. At least so we interpret nature, whether it have this design or not. But the interest which we here take in beauty has only to do with the beauty of Nature; it vanishes altogether as soon as we notice that we are deceived and that it is only Art--vanishes so completely that taste can no longer find the thing beautiful or sight find it charming. What is more highly praised by poets than the bewitching and beautiful note of the nightingale in a lonely copse on a still summer evening by the soft light of the moon? And yet we have instances of a merry host, where no such songster was to be found, deceiving to their great contentment the guests who were staying with him to enjoy the country air, by hiding in a bush a mischievous boy who knew how to produce this sound exactly like nature (by means of a reed or a tube in his mouth). But as soon as we are aware that it is a cheat, no one will remain long listening to the song which before was counted so charming. And it is just the same with the songs of all other birds. It must be Nature or be regarded as Nature, if we are to take an immediate _interest_ in the Beautiful as such; and still more is this the case if we can require that others should take an interest in it too. This happens as a matter of fact when we regard as coarse and ignoble the mental attitude of those persons who have no _feeling_ for beautiful Nature (for thus we describe a susceptibility to interest in its contemplation), and who confine themselves to eating and drinking--to the mere enjoyments of sense.
