8. What is Mortal in Man?

For spiritual science, however, this purely philosophical approach, based on concepts and ideas of the external world, is from the outset something — forgive the somewhat trivial comparison — it is this philosophy, based purely on rational arguments, as one often says, is something that can just as little arrive at real results about the spiritual life, just as little get the spirit into human knowledge, as man can nourish himself by eating himself. Just as the process of nutrition must take hold of something that is outside its structure if it is to serve the human or animal organism, so human cognition must take hold of something that lies outside the mere connection and concatenation of concepts and ideas if the true cognitive needs of the human being are to be satisfied. In the second half of the nineteenth century, we have an example of how materialism, in its strict logic, is able to proceed from conclusion to conclusion, but because it is unable to really engage with a spiritual reality, it nevertheless becomes entangled in contradictions, which are not noticed by this materialistic world. conclusion to conclusion, but because it is impossible for it to really engage with a spiritual reality, it nevertheless becomes entangled in contradictions, which are not noticed by this materialistic world view itself, but which are noticed by those who have trained themselves to a certain universality of thought. In his book 'Old and New Faith', David Friedrich Strauß also presents Goethe's idea of immortality among the various proofs of human immortality that he wants to refute. He takes up this idea and behaves very strangely in doing so. David Friedrich Strauß does admit that there is something heroic about Goethe's idea of immortality, but then he belittles this heroism – one would like to use the word that Nietzsche coined for David Friedrich Strauß – like a real philistine. Goethe made not one but many statements about human immortality. For Strauß, only the one that I will mention now comes into consideration.
