Lecture II

In the materialistic age people have used a materialistic comparison—that the brain excretes thoughts as the liver excretes gall. That is nonsense, for the reverse is true. The brain is excreted by the thoughts, separated off continually and continually replaced by the metabolic organism. A modern scientific man will not be able to find anything right in such an idea; he will say that it all refers equally to the animal, the animal has a brain and such and such organs, and so on. This shows. however, an ignorance of himself; anyone who speaks like this of man and animal makes the same mistake as a legislator would make if he had all the razors to be found at all the barbers of a town carried to the restaurants, since he connected with a knife solely the idea of eating and concluded that an instrument formed in a certain way could only have one purpose.
