As a matter of fact, Hegel and Schopenhauer, each in his own way, partly attempted to make an admission of this kind, but they derived small profit from it. Let us try to draw some conclusions from the foregoing. Certainly, while logic can be useful, it would be unjustifiable recklessness to refuse its services. Nor are the conclusions devoid of interest, as we shall see. First of all, when you speak, never trouble to be consistent with what you said before: that will put an unnecessary check upon your freedom, which, without that additional fetter, is already chained in words and grammatical forms. When you are listening to a friend or reading a book, do not assign great value to individual words or even to phrases. Forget separate thoughts, and give no great consideration even to logically arranged ideas. Remember that though your friend desires it, he cannot express himself save by ready-made forms of speech. Look well to the expression of his face, listen to the intonation of his voice--this will help you to penetrate through his words to his soul. Not only in conversation, but even in a written book, can one over-hear the sound, even the timbre of the author's voice, and notice the finest shades of expression in his eyes and face. Do not fasten upon contradictions, do not dispute, do not demand argument: only listen with attention. In return for which, when you begin to speak, you also will have to face no dispute, nor to produce arguments, which you know well you neither have nor could have. So you will not be annoyed by having pointed out to you your contradictions which you know well were always there, and will always be there, and with which it is painful, nay quite impossible, for you to part. Then, then--and this is most important of all--you will at last be convinced that truth does not depend on logic, that there are no logical truths at all, that you therefore have the right to search for what you like, how you like, without argument, and that if something results from your search, it will not be a formula, not a law, not a principle, not even an idea! Only think: while the object of search is 'truth,' as it is understood nowadays, one must be prepared for anything. For instance, the materialists will be right, and matter and energy are the basis of the world. It does not matter that we can immediately confound the materialists with their conclusions. The history of thought can show many cases of the complete rehabilitation of opinions that have been cast off and reviled. Yesterday's error may be to-morrow's truth, even a self-evident truth. And apart from its content, wherein is materialism bad? It is a harmonious, consistent, and well-sustained system. I have already pointed out that the materialistic conception of the world is just as capable of enchanting men as any other--pantheistic or idealistic. And since we have come so far, I confess that in my opinion no ideas at all are bad in themselves: so
