Descartes cannot doubt his own existence, as captured in his famous statement "Cogito, ergo sum" - "I think, therefore I am."
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' philosophy on reality actually shows that we cannot for sure know that we aren' dreaming. In fact, Descartes believed that we are not sure of anything, except for the fact that we exist because we use logic and reason. Sorry that this doesn't answer your question, but the point of this ideology is for others to try to show Descartes how we know FOR CERTAIN that we are not dreaming right now....harder to do than one would think.
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.
Descartes found it impossible to doubt his own existence. The reason for this was that he felt that thoughts had to come from himself.
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

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 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.
