12. The Essence of Spiritual Science and the Knowledge of the Transcendental World
When the natural scientist comes and says: From my way of thinking I must reject this, — then the spiritual researcher must say to the natural scientist: So give your reasons. Then the natural scientist gives the reason: The soul life is dependent on the brain. The spiritual researcher will say: You are right. He will agree with the natural scientist on all points. But he will say: Only then, after one has entered your territory, does the investigation of the spiritual-soul life begin, which has to do with completely different forces than those for which natural science is fully justified. Therefore, it is indeed a thoroughly understandable misunderstanding when one or the other objection is raised against spiritual science from the point of view of natural science. Spiritual science knows very well what it has in natural science. And it would be dilettantism in the field of spiritual science if it were to oppose natural science. And nor can it be said that the spiritual researcher cultivates superstition in any way.
