Who said, "Cogito ergo sum (I think, therefore I am)"?

René Descartes (March 31, 1596 – February 11,1650) was a French philosopher, mathematician, and scientist. Much of subsequent Western philosophy is a response to his writings, which are studied closely to this day. He spent about 20 years of his life in the Dutch Republic. His best known philosophical statement is "Cogito ergo sum" (French: Je pense, donc je suis; I think, therefore I am), found in part IV of Discourse on the Method (1637; written in French but with inclusion of "Cogito ergo sum") and §7 of part I of Principles of Philosophy (1644; written in Latin).

A friend used to say, 'I ponder, therefore I may be'. We live in uncertain times.

I have conscious recognition; therefore, I exist. This is the way I learned it in college philosophy classes.

Just yesterday I thought of this quote and Neitzche's rebuttal. Couldn't remember the phrasing of Neitzche and tried to look it up but couldn't find the quote. "The mind who is thinking is not....." can anyone help?
