who said this: "i think therefore, i am" why? when? where?

Answer 1

As I understand it this was not just an idea that Descartes came up with, but was the end result of his painstaking process of eliminating everything that contained any kind of uncertainty, outside of the artificial certainty provided by mathematics (which was an important aspect since he was a great mathematician as well) In other words, all we really know for certain is that we exist, and we can know this simply because we think. It doesnt seem that this was intended to be the most fundamental thing that can be said about existence though, because a sense of existence doesn't necessarily require thought, it only requires awareness.

Answer 2

Rene Descartes.

When? and Where? i dont know the specifics but you should try reading his Discourse. He was born 1596 in France.

Why?
Part IV of his Discourse "narrates Descartes' increasing desperation to find some certain truth upon which he can build a solid structure of certainty; while mulling over the problem, Descartes suddenly realizes that the very fact that he is thinking proves that he, Descartes, exists: Cogito, ergo sum , "I think, therefore I am." For if he didn't exist, he wouldn't be thinking."

Answer 3

Rene Descartes

Answer 4

Descartes,

Cogito, ergo sum" (Latin: "I am thinking, therefore I exist", or traditionally "I think, therefore I am") is a philosophical statement by René Descartes, which became a foundational element of Western philosophy. "Cogito ergo sum" is a translation of Descartes' original French statement: "Je pense, donc je suis", which occurs in his Discourse on Method (1637).

Although the idea expressed in "cogito ergo sum" is widely attributed to Descartes, many predecessors offer similar arguments —particularly St. Augustine of Hippo in De Civitate Dei (books XI, 26), who also anticipates modern refutations of the concept. (See Principles of Philosophy, §7: "Ac proinde haec cognitio, ego cogito, ergo sum, est omnium prima et certissima etc.").

Answer 5

Yep, it was Descartes. That quote applies to how one can know that something is true, since anything which can be doubted might not be true. For a detailed discussion, see link below:
