Descartes found it impossible to doubt his own existence. The reason for this was that he felt that thoughts had to come from himself.
i am i exist
René Descartes was certain about his own existence, famously encapsulated in the phrase "Cogito, ergo sum," which translates to "I think, therefore I am." He concluded that the act of thinking is undeniable proof of one's own existence, as even doubt implies a thinking subject. This foundational belief became a cornerstone of his philosophical framework. Descartes used this certainty to build further arguments about knowledge and existence.
René Descartes believed in the concept of an absolute truth that could be established through reason and rational thought. He famously asserted "Cogito, ergo sum" ("I think, therefore I am"), positing that the very act of doubt or thinking is proof of one's existence and a foundational truth. Descartes sought to build knowledge on this certainty, arguing that through systematic doubt and methodical reasoning, one could arrive at undeniable truths about existence and the nature of reality. His approach laid the groundwork for modern philosophy and emphasized the importance of skepticism in the pursuit of knowledge.

That he existed.
Descartes cannot doubt his own existence, as captured in his famous statement "Cogito, ergo sum" - "I think, therefore I am."
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.
i am i exist
The one thing that Descartes couldn't doubt was his thoughts, he thinks there for he is. To be a good philosopher, you need to be skeptical (to ask a lot of questions), Descartes asked questions then doubted them. That brought in dualism. He is considered one of the greatest thinkers of the enlightenment period.

Descartes' evil genus argument is about a creature with god-like power that can deceive Descartes regarding absolutely anything. The purpose of conceptualizing such a creature is to cast everything you think you know into doubt so that you might see what remains.
One famous quote by Descartes is "Cogito, ergo sum" which means "I think, therefore I am." This quote signifies Descartes' emphasis on the importance of doubt and skepticism in the pursuit of knowledge. It highlights the idea that the act of thinking proves one's existence, as the very act of doubting or thinking about one's existence implies that one must exist in some form. This quote is a foundational concept in Descartes' philosophy, as it serves as the starting point for his method of doubt and his quest for certain knowledge.
Essentially, Descartes' philosophy was based on the notion of methodical doubt, that is, to doubt absolutely everything that one could not be absolutely certain of. Descartes considered the principal weakness of his predecessor's philosophy to be its subjectivity. He felt that the premises from which previous philosophers deduced truths were not necessarily accurate, and thus did not provide any intellectual certainty. Consequently, Descartes used methodical doubt as the starting point for his philosophy.
Descartes meant that the act of thinking itself proves one's existence. By doubting everything, including the existence of the external world, he concludes that the fact that he is able to doubt and think means he must exist as a thinking thing.
René Descartes is often associated with the quote "dubito, ergo cogito, ergo sum," which translates to "I doubt, therefore I think, therefore I am." This reflects his belief that one can only trust in their own existence based on the process of reason and doubt.
Descartes' systematic doubt was a method of questioning all beliefs to find the foundational truth. This process led him to his famous saying, "Cogito ergo sum," which translates to "I think, therefore I am." It highlights the certainty of one's existence as a thinking being, even in the face of doubt about everything else.
Descartes had one daughter.
