Lecture IV
Today I should like to present something that will supplement what I said last Sunday about the nature of the human sense organism.[^3] I shall begin by pointing out a certain contradiction that I have often dwelt on before. On the one hand, without the general public knowing much about it, but nevertheless thinking along these lines, there exists the condition today of being infected in a sense with the natural scientific mode of thinking. On the other hand, we have one type of person still holding to the old traditional belief regarding moral or religious ideals; another has only skepticism and doubt, while for a third it is a matter of indifference. This great contradiction basically stirs and vibrates through all humanity today: How is the inevitable course of natural events related to the validity of ethical, moral and religious ideals?
