THE PLATONIC IDEA: THE OBJECT OF ART. 245 the ground of knowing. The mental faculty upon which it makes the greatest claim is memory, for it is necessary to recollect all the earlier propositions which are referred to. Experience has also proved that men of great artistic genius have no faculty for mathematics; no man was ever very distinguished for both. Alfieri relates that he was never able to understand the fourth proposition of Euclid. Goethe was constantly reproached with his want of mathematical knowledge by the ignorant opponents of his theory of colours. Here certainly, where it was not a question of calculation and measurement upon hypothetical data, but of direct knowledge by the understanding of causes and effects, this reproach was so utterly absurd and inappropriate, that by making it they have exposed their entire want of judgment, just as much as by the rest of their ridiculous arguments. The fact that up to the present day, nearly half a century after the appearance of Goethe's theory of colours, even in Germany the Newtonian fallacies still have undisturbed possession of the professorial chair, and men continue to speak quite seriously of the seven homogeneous rays of light and their different refrangibility, will some day be numbered among the great intellectual peculiarities of men generally, and especially of Germans. From the same cause as we have referred to above, may be explained the equally well-known fact that, conversely, admirable mathematicians have very little susceptibility for works of fine art. This is very naïvely expressed in the well-known anecdote of the French mathematician, who, after having read Racine's "Iphigenia," shrugged his shoulders and asked, "Qu'est ce que cela prouve?" Further, as quick comprehension of relations in accordance with the laws of causality and motivation is what specially constitutes prudence or sagacity, a prudent man, so far as and while he is so, will not be a genius, and a man of genius, so far as and while he is so, will not be a prudent man. Lastly, perceptive knowledge generally,
