Nietzsche also criticizes Rene Descartes’ notion of “I think,” labeling it an “immediate certainty” that is ultimately misleading and falsifiable (Nietzsche 22-23). Descartes, in Discourse on the Method of Rightly Conduction the Reason and Seeking for Turth in the Sciences, remarked that, “I noticed that whilst I thus wished to think all things false, it was absolutely essential that ‘I’ who thought this should be somewhat, and remarking that this truth ‘I think, therefore I am’ was so certain and so assured that all the most extravagant suppositions brought forward by the skeptics were incapable of shaking it…” (Barash 81). Nietzsche does dare to shake the notion by saying that there are a number of assumptions used in Descartes’ so-called truth. One of these assumptions is that I, the subject of the phrase, is actively conducting the thinking instead of the thinking spontaneously arriving to I. With this example, Nietzsche expresses the importance of not falling for a seemingly simple array of words (Nietzsche 24-25).
