Lecture I

We can certainly see from this that Spiritual Science, which has to develop sound principles for the understanding of life, has work to do in the most varied domains of life; and that it is first of all necessary to learn how to think, and to get to know the inner laws and impulses of thought. Otherwise all sorts of grotesque things can befall one. Thus for example a certain man to-day is stumbling and bumbling over the problem of “thought and language”. He is the celebrated language-critic Fritz Mauthner, who has also written lately a large philosophical dictionary. His bulky Critique of Language is already in its third edition, so for our contemporaries it is a celebrated work. There are plenty of ingenious things in this book, and plenty of dreadful ones. Thus one can find here a curious example of faulty thinking—and one runs up against such blunders in almost every five lines—which leads the worthy Mauthner to throw doubt on the need for logic. “Thinking”, for him, is merely speaking; hence there is no sense in studying logic; grammar is all one needs. He says also that since there is, rightly speaking, no logic, logicians are fools. And then he says: In ordinary life, opinions are the result of inferences, and ideas come from opinions. That is how people go on! Why should there be any need for logic when we are told that opinions arise from inferences, and ideas from opinions? It is just as clever as if someone were to say: “Why do you need botany? Last year and two years ago the plants were growing.” But such is the logic one finds in a man who prohibits logic. One can quite understand that he does prohibit it. There are many more remarkable things in this strange book—a book that, in regard to the relation between thought and language, leads not to lucidity but to confusion.
