On the prejudices of philosophers ‘I think,’ I get a whole set of bold claims that are difficult, perhaps impos- sible, to establish, – for instance, that I am the one who is thinking, that there must be something that is thinking in the fir st 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 retro- spective comparison with other types of ‘knowing,’ this present state has absolutely no ‘immediate certainty’ for me.” – In place of that “imme- diate cer tainty” 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 mat- ter, 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 philoso- pher 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?” – As far as the superstitions of the logicians are concerned: I will not stop emphasizing a tiny little fact that these superstitious men are loath to admit: that a thought comes when “it” wants, and not when “I” want. It is, therefore, a falsification of the facts to say that the subject “I” is the condition of the predicate “think.” It thinks: but to say the “it” is just that famous old “I” – well tha t is just an assumption or opinion, to put it mildly, and by no means an “immediate certainty.” In fact, there is already too much packed into the “it thinks”: even the “it” contains an interpretation of the process, and does not belong to the process itself.
