The Latin cogito, ergo sum, usually translated into English as "I think, therefore I am", is a philosophical statement that was made by René Descartes. The phrase originally appeared in French as je pense, donc je suis in his 1637 Discourse on the Method, so as to reach a wider audience than Latin would have allowed.

What is meant by Cogito ergo sum?

cogito, ergo sum, (Latin: “I think, therefore I am) dictum coined by the French philosopher René Descartes in his Discourse on Method (1637) as a first step in demonstrating the attainability of certain knowledge.

Why the cogito is wrong?

The problem of the solipsistic argument of the cogito is that nothing more exists outside the self's being a thinking thing. It only proves the existence of oneself insofar as the thinking I is concerned, and does not prove the idea and the existence of other things other than the self.
