Eleventh Lecture

Before the above-mentioned beings gained influence over man in the course of evolution, he was so organized that he reacted far more powerfully than today toward evil pressing upon him from without. But in proportion to the influence that they gained over him, he lost the instincts he had possessed for what was not right. Formerly, man's whole organization was such that he had fine instincts as to what was not right for him. Substances that are taken into the stomach today and there cause illness were then rejected simply through instinct. Gazing backward in time we come to periods when man stood in a delicate relationship to the forces of his environment, reacting sensitively to the forces in his surroundings. In this respect man grew ever less sure, less capable of rejecting what was not serviceable to him.
