IV. Knowledge of the Human Being According to Body, Soul or Spirit, Brain and Thinking — The Liver as a Sensory Organ

Another human organ that perceives is the eye. But the eye perceives the external world so strongly precisely because it sits almost separately in the head. It is completely inside this bone cavity, but it is almost a separate organ. You can take it out, and it lies completely separate from the body in this bone cavity. The other senses do not lead us into the outside world as much as the eye does. When you hear, you still experience something inwardly. Music is therefore more inward than seeing. The eye is designed in such a way that it does not belong so much to the human body, but rather to the outside world.
