i am i exist
Descartes found it impossible to doubt his own existence. The reason for this was that he felt that thoughts had to come from himself.
That he existed.
Only one thing: certain death.
One of Descartes simple but important contributions to the field of mathematics is his notation, which made exponents into a superscript after the root. He also came up with the formula for reflection and refraction and the Cartesian plane
Descartes was a very philosophical person. In fact he's the father of modern philosophy He thought the world on 3 axes, he had to do this while he was trying to solve the riddle of pappus. But to be more specific he invented the coordinate system while he was sleeping with one oven at he's side and had 3 dreams. the answer you're looking for, is that "Descartes dreamt the coordinate system, then he did it reality on a compendium of one of he's 3 books of philosopy"
Unlike Descartes, Spinoza believed that the mind was an extension of the body, and vice versa. He thought that there was only one type of substance, a divine substance, of which the mind and body were part. As one thing, the mind and body could interact in harmony, not the discord Descartes was concerned with.

Descartes cannot doubt his own existence, as captured in his famous statement "Cogito, ergo sum" - "I think, therefore I am."
Descartes tried to find out if such a thing as "ultimate truth" really exists. He thought about almost everything and found out that he could destroy / counter-argue himself about everything! He thus concluded that he can be certain about nothing, except one thing: that he thinks (since even if he counter-argued that he isn't thinking, he should be thinking about that!). The phrase "I think therefore I am" is something that tells an almost universal truth and it was not difficult to be accepted by other westerners.
Systematic doubt. Descartes could doubt everything except for one thing - his own existence. Cogito ergo sum - "I think, therefore I am" - became his first principle.
Cogito Ergo Sum means "I think, therefore I am" in Latin. Descartes concluded that even if he doubted everything, he could not doubt his own existence as a thinking being. Thus, the fact that he was able to think meant that he must exist.
Descartes had one daughter.
One answer could be Rene Descartes.
Descartes meant that the act of doubting one's existence proves that one must exist to do the doubting. "I think, therefore I am" (Cogito, ergo sum) is a foundational element of his philosophy, serving as a starting point for establishing certainty in knowledge.
Descartes' method of doubt was a systematic approach to examine the foundations of knowledge by doubting everything that could possibly be doubted. He aimed to find a firm foundation for knowledge by doubting even his own existence, ultimately arriving at his famous conclusion, "Cogito, ergo sum" (I think, therefore I am). Through this method, Descartes sought to establish a new epistemological foundation based on indubitable truths.
Descartes believed that the human mind contained particular innate ideas, one of which was infinity. Rene Descartes was a French philosopher.
you have to do a certain thing at one of the places i think!
