We cannot venture to say much about genius and the mystery of it. In it and its creative power something of the spirit, the nature of the spirit, seems to look up at us, as we might think of it in itself and apart from the limits of existence in time and space. It is usually most obvious and most accessible to us in the domain of art. But it has its place too in the realm of science. And it is most of all genius, and therefore most inaccessible to us ordinary mortals, in the domain of religion.
