another form in art and literature.[39] The scientific imagination should be controlled by judgment and work in strict subordination to the facts. In art and literature, on the other hand, the imagination should be free. Genius and originality are indeed in strict ratio to this freedom. “In the fairy land of fancy,” says Young, “genius may wander wild; there it has a creative power, and may reign arbitrarily over its own empire of chimeras.” (The empire of chimeras was later to become the tower of ivory.) This sheer indiscipline of the literary imagination might seem in contrast with the discipline of the scientific imagination an inferiority; but such was not the view of the partisans of original genius. Kant, indeed, who was strongly influenced in his “Critique of Æsthetic Judgment” by these English theorists,[40] inclined to deny genius to the man of science for the very reason that his imagination is so strictly controlled. The fact would seem to be that a great scientist, a Newton let us say, has as much right to be accounted a genius as Shakespeare. The inferiority of the genius of a Newton compared with that of a Shakespeare lies in a certain coldness. Scientific genius is thus cold because it operates in a region less relevant to man than poetic genius; it is, in Bagehot’s phrase, more remote from the “hearth of the soul.” The scientific and the literary imagination are indeed not quite so sharply contrasted by most of the theorists as might be inferred from what I have said; most of them do not admit that the literary imagination should be entirely free to wander in its own “empire of chimeras.” Even literary imagination, they maintain, should in some measure be under the surveillance of judgment or taste. One should observe, however, that the judgment or taste that is supposed to control or restrict genius is not associated with the imagination. On the contrary, imagination is associated entirely with the element of novelty in things, which means, in the literary domain, with the expansive eagerness of a man to get his own uniqueness uttered. The genius for the Greek, let us remind ourselves, was not the man who was in this sense unique, but the man who perceived the universal; and as the universal can be perceived only with the aid of the imagination, it follows that genius may be defined as imaginative perception of the universal. The universal thus conceived not only gives a centre and purpose to the activity of the imagination, but sets bounds to the free expansion of temperament and impulse, to what came to be known in the eighteenth century as nature.
