Beyond Good and Evil

On the prejudices of philosophers

16 There are still harmless self-observers who believe in the existence of “immediate certainties,” such as “I think,” or the “I will” that was Schopenhauer’s superstition: just as if knowledge had been given an object here to seize, stark naked, as a “thing-in-itself,” and no falsification took place from either the side of the subject or the side of the object. But I will say this a hundred times: “immediate certainty,” like “absolute knowledge” and the “thing in itself ” contains a contradictio in adjecto. For once and for all, we should free ourselves from the seduction of words! Let the people believe that knowing means knowing to the very end; the philosopher has to say: “When I dissect the process expressed in the proposition ‘I think,’ I get a whole set of bold claims that are difficult, perhaps impossible, to establish, – for instance, that I am the one who is thinking, that there must be something that is thinking in the first place, that thinking is an activity and the effect of a being who is considered the cause, that there is an ‘I,’ and finally, that it has already been determined what is meant by thinking, – that I know what thinking is. Because if I had not already made up my mind what thinking is, how could I tell whether what had just happened was not perhaps ‘willing’ or ‘feeling’? Enough: this ‘I think’ presupposes that I compare my present state with other states that I have seen in myself, in order to determine what it is: and because of this retrospective comparison with other types of ‘knowing,’ this present state has absolutely no ‘immediate certainty’ for me.” – In place of that “immediate certainty” which may, in this case, win the faith of the people, the philosopher gets handed a whole assortment of metaphysical questions, genuinely probing intellectual questions of conscience, such as: “Where do I get the concept of thinking from? Why do I believe in causes and effects? What gives me the right to speak about an I, and, for that matter, about an I as cause, and, finally, about an I as the cause of thoughts?” Whoever dares to answer these metaphysical questions right away with an appeal to a sort of intuitive knowledge, like the person who says: “I think and know that at least this is true, real, certain” – he will find the philosopher of today ready with a smile and two question-marks. “My dear sir,” the philosopher will perhaps give him to understand, “it is improbable that you are not mistaken: but why insist on the truth?”
