Perception of the Nature of Thought

You know that Ahriman and Lucifer are harmful spirits as long as one is not aware of them, as long as they work in secret. As long as they do not emerge and let men face them eye to eye spiritually Ahriman and Lucifer are harmful in one or another way. Let us suppose that a philosopher appears who develops thought of such a nature that one can grasp it in merely earth existence. He develops thoughts that can live through the instrument of earthly reasoning. That is Hegelian thought! It is pure thought, but only such as can be grasped with the instrument of the physical body and this as we know ends at death.
