It is absolutely from his vision of the whole, in which the genius always lives, that he gets his sense of the parts. He values everything within him or without him by the standard of this vision, a vision that for him is no function of time, but a part of eternity. And so the man of genius is the profound man, and profound only in proportion to his genius. That is why his views are more valuable than those of all others. He constructs from everything his ego that holds the universe, whilst others never reach a full consciousness of this inner self, and so, for him, all things have significance, all things are symbolical. For him breathing is something more than the coming and going of gases through the walls of the capillaries; the blue of the sky is more than the partial polarisation of diffused and reflected light; snakes are not merely reptiles that have lost limbs. If it were possible for one single man to have achieved all the scientific discoveries that have ever been made, if everything that has been done by the following: Archimedes and Lagrange, Johannes Müller and Karl Ernst von Baer, Newton and Laplace, Konrad Sprengel and Cuvier, Thucydides and Niebuhr, Friedrich August Wolf and Franz Bopp, and by many more famous men of science, could have been achieved by one man in the short span of human life, he would still not be entitled to the denomination of genius, for none of these have pierced the depths. The scientist takes phenomena for what they obviously are; the great man or the genius for what they signify. Sea and mountain, light and darkness, spring and autumn, cypress and palm, dove and swan are symbols to him, he not only thinks that there is, but he recognises in them something deeper. The ride of the Valkyrie is not produced by atmospheric pressure and the magic fire is not the outcome of a process of oxidation.
