For that the art may attain a high degree of excellence for itself and much distinction for its professors, without calling in the aid of imagination, is evident enough on this side of the globe, without travelling to the other.
Take, on the other hand, a branch of science which, to the average layman, seems peculiarly unimaginative, the science of mathematics.
Yet at the risk of appearing to cast doubts upon the validity of its conclusions, it might be called the most imaginative product of human thought; for it is simply one vast imagination based upon a few so-called axioms, which are nothing more nor less than the results of experience.

It is none the less imaginative because its discoveries always accord subsequently with fact, since man was not aware of them beforehand.

Nor are its inevitable conclusions inevitable to any save those possessed of the mathematician's prophetic sight.

Once discovered, it requires much less imagination to understand them.

With the light coming from in front, it is an easy matter to see what lies behind one.
So with other fabrics of human thought, imagination has been spinning and weaving them all.
