If we consider how there lies something so entirely idiosyncratic, so thoroughly original, in every human countenance, and that it presents a whole which can only belong to a unity consisting entirely of necessary parts by virtue of which we recognise a known individual out of so many thousands, even after long years, although the possible variations of human features, especially of one race, lie within very narrow limits, we must doubt whether anything of such essential unity and such great originality could ever proceed from any other source than from the mysterious depths of the inner being of nature; but from this it would follow that no artist could be capable of really reproducing the original peculiarity of a human countenance, or even of composing it according to nature from recollection. Accordingly what he produced of this kind would always be only a half true, nay, perhaps an impossible composition; for how should he compose an actual physiognomical unity when the principle of this unity is really unknown to him? Therefore, in the case of every face which has merely been imagined by an artist, we must doubt whether it is in fact a possible face, and whether nature, as the master of all masters, would not show it to be a bungled production by pointing out complete contradictions in it. This would, of course, lead to the principle that in historical paintings only portraits ought to figure, which certainly would then have to be selected with the greatest care and in some degree idealised. It is well known that great artists have always gladly painted from living models and introduced many portraits. Although, as is explained in the text, the real end of painting, as of art in general, is to make the comprehension of the (Platonic) Ideas of the nature of the world easier for us, whereby we are at once thrown into the state of pure, _i.e._, will‐less, knowing, there yet belongs to it besides this an independent beauty of its own, which is produced by the mere harmony of the colours, the pleasingness of the grouping, the happy distribution of light and shade, and the tone of the whole picture. This accompanying subordinate kind of beauty furthers the condition of pure knowing, and is in painting what the diction, the metre, and rhyme are in poetry; both are not what is essential, but what acts first and immediately.
