VII. The Questions of Life and the Riddle of Death I

Nevertheless, in natural sciences it is exactly the same way; one has to experience these things. If a human being has never seen a whale fish, zoology cannot prove that there is a whale fish. With it, some objections disprove themselves. Schopenhauer characterised a part of his system with the fact that he said, the world is my idea.—With it, he stated that one cannot separate percepts from mental pictures. However, there is an easy, even if trivial rebuttal. If we imagine that we touch our skin with an iron piece of 900 degrees centigrade, we can imagine the pain probably in thoughts, but an only imagined hot iron does not cause ache as a real one does. There is a proof that is produced by life. The same applies to the spiritual life; it must be experienced to the end.
