### Step 1: English Response
René Descartes, a prominent philosopher, is perhaps most famous for his statement "Cogito, ergo sum" or "I think, therefore I am." This statement is a cornerstone of his philosophical system and is rooted in his quest for absolute certainty in the face of skepticism. Descartes' methodical doubt is a systematic process through which he attempts to arrive at indubitable knowledge. Here's how he knows he exists:
Descartes' Method of Doubt:
Descartes begins with a method of doubt, questioning everything he has previously accepted as true. He aims to strip away all beliefs that are not absolutely certain to find a foundation for knowledge that is immune to doubt.
The Doubt of Existence:
He considers the possibility that his entire sensory experience could be an illusion, orchestrated by an evil demon bent on deceiving him. Even mathematical truths, which he once thought were certain, are subject to doubt if an all-powerful being is intent on misleading him.
Cogito (I Think):
Despite this radical doubt, there is one thing that Descartes finds indubitable: the very act of doubting. To engage in doubt, to question one's own existence, there must be a thinking entity. This thinking entity is the self, the "I" that is doing the thinking. Even if Descartes were to doubt the existence of his body, the fact that he can doubt, that he has thoughts, is undeniable.
Ergo Sum (Therefore I Am):
From the act of thinking, Descartes concludes that he must exist. The certainty of his own existence does not come from the content of his thoughts but from the mere fact that he is thinking. The thought itself is proof of existence. This is not a proof that he is a physical being with a body, but rather that he is a thinking being, a mind.
Existence Beyond the Thinking Mind:
Initially, Descartes does not equate the thinking mind with the physical body. He is certain of the existence of a thinking thing, but he has not yet established that this thinking thing is a physical body. Descartes' later work attempts to bridge the gap between the mind and the body, but the initial certainty of his own existence is based solely on the act of thinking.
The Foundation for Further Knowledge:
Once Descartes has established that he exists as a thinking being, he uses this as a foundation to rebuild his system of knowledge. He then argues for the existence of God, using the idea that the concept of a perfect being cannot originate from an imperfect mind, and thus must have been placed there by a perfect being. From the existence of a perfect, non-deceiving God, he deduces that his clear and distinct ideas are true, allowing him to rebuild the edifice of knowledge on a more secure foundation.
Descartes' proof of his own existence is not based on external evidence or empirical observation but on a logical deduction from the act of doubting itself. It is a foundational piece of his philosophy and a significant contribution to epistemology, the study of knowledge.

With this in mind, Descartes sets out to prove, using only reason, that some things are beyond doubt. ... First he decides he can be certain that he exists, because if he doubts, there must be a thinking mind to do the doubting. He does not yet accept that he is a thinking mind inside a body.
