Lecture IV

The world is boundless, both qualitatively and quantitatively. And it will be a blessing when there are individual souls who wish for clear vision with regard to that which is appearing in our day with such terrible overweening narrow-mindedness, and wants to be “universal”. I might say: “With bleeding heart I declare that the greatest hindrance to knowledge of how a preparatory work of thought-activity is carried out in the brain, how the brain is thereby made into a mirror and the life of the soul reflected from it—a fact which could throw endless light on much other physiological knowledge—the greatest hindrance to the knowledge of this fact is the crazy modern physiology which speaks of two kinds of nerves, the ‘motor’ and the ‘sensory’ nerves.” (I have touched on this in many lectures already.) In order to produce this theory, which crops up everywhere in physiology, it is a fact that physiology had first to lose all understanding. Hence it is a theory now recognized all over the earth, and it acts as a hindrance to all true knowledge of the nature of thought and the nature of the soul. Never will it be possible to understand human thought if physiology sets up such an obstacle to true knowledge. But things have gone so far that an indefensible physiology forms the introduction to every textbook of psychology and teaching about the mind, and makes it dependent on this falsity. Therewith the door is bolted also against knowledge of cosmic thought.
