λόγους έξ ων η φύσις). Art therefore does not belong to nature, but adds beauty where it is wanting in nature: Phidias did not represent Jove because he had seen him, but such as he would appear if he wished to reveal himself to mortal eyes.[28] The beauty of natural things is the archetype existing in the soul, the sole source of natural beauty.[29] [Sidenote: _The scientific tendency. Aristotle._] This affirmation of Plotinus and of neo-Platonism is the first true and proper affirmation of mystical Æsthetic, destined to such high fortunes in modern times, especially in the first half of the nineteenth century. But the attempts at a true Æsthetic, excluding certain luminous but incidental observations to be found even in Plato: for instance, that the poet should weave fables, not arguments (μύθους άλλ' ού λόγους),[30] go back to Aristotle and are altogether independent of his few and feeble speculations as to the beautiful. Aristotle by no means agreed with the Platonic condemnation; he felt (as indeed Plato himself had suspected) that such a result could not be altogether true, and that some aspect of the problem must have been neglected. When in his turn he attempted to find a solution, he found himself in more advantageous conditions than his great predecessor, since he had already overcome the obstacle that arose from the Platonic doctrine of ideas, a hypostasis of concepts and abstractions. The ideas were for him simply concepts, and reality presented itself in a far more lively manner, not as a diminution of ideas, but as a synthesis of matter and form, it was thus much more easy for him to recognize the rationality of mimesis in his general philosophical doctrine and to assign to it its right place; and indeed it seems generally clear to Aristotle that mimesis, being proper to man by nature, is contemplation or theoretic activity; although he sometimes seems to forget this (as when he confuses imitation with the case of boys, who acquire their first knowledge by following an example[31]), and although his system, which admits practical sciences and poietic activities (distinguished from the practical as leaving a material object behind them), disturbed the firm and constant consideration of artistic mimesis and poetry as a theoretical activity. But if it is a theoretical activity, by what characteristic is poetry distinguished both from _scientific_ knowledge and from _historical_ knowledge? This is the way Aristotle states the problem concerning the nature of art, and this is the true and only way of stating it. Even we moderns ask ourselves in what way art is distinguished from history and from science, and what this artistic form can be, which has the ideality of science and the concreteness and individuality of history. Poetry, answers Aristotle, differs from history, because, while the latter draws things that have happened (τα γενόμενα), poetry draws things that may possibly happen (οια αν
