All we can say of this notion of reproducing things in shadow or representative shape is that it exists nowhere in nature except in man; and that we cannot even talk about it without treating man as something separate from nature. In other words, every sane sort of history must begin with man as man, a thing standing absolute and alone. How he came there, or indeed how anything else came there is a thing for theologians and philosophers and scientists, and not for historians. But an excellent test case of this isolation and mystery is is the matter of the impulse of art.
