“”Besides that”, continues Schopenhauer, “these manifestations present to us a substantial and perfectly logical contradiction to materialism, and even to naturalism, because in the light of such manifestations, that order of things in nature which both these philosophies seek to present as absolute and the only genuine, appears before us on the contrary purely phenomenal and superficial, and containing at the bottom of it a substance of things a parte and perfectly independent of its own laws.
That is why these manifestations – at least from a purely philosophical point of view – among all the facts which are presented to us in the domain of experiment, are beyond any comparison the most important. Therefore, it is the duty of every scientist to acquaint himself with them.””
