Descartes believes in looking for the truth to answers. In order to do this, doubt must be used until the conclusion is reached.
Descartes believed that doubt was a crucial tool in the search for truth. By subjecting all his beliefs to doubt, he aimed to find a foundation of knowledge that could not be doubted. This led him to his famous statement "Cogito, ergo sum" (I think, therefore I am), which served as the starting point for his philosophical system.
Descartes cannot doubt his own existence, as captured in his famous statement "Cogito, ergo sum" - "I think, therefore I am."
In Descartes' Meditations, doubt serves as a tool for philosophical inquiry by challenging and ultimately casting skepticism on the reliability of sense perceptions and beliefs. Through methodical doubt, Descartes aims to uncover indubitable truths and establish a foundation of certain knowledge upon which to build his philosophical system. Doubt, therefore, acts as a catalyst for Descartes' quest for certainty and the establishment of foundational principles in his philosophy.
RenΓ© Descartes, a French philosopher, created the system of systematic doubt. In his work "Meditations on First Philosophy," Descartes employs the method of doubt to question all his beliefs in order to find a foundation of certainty in knowledge.
Descartes' radical doubt refers to his method of systematically doubting all beliefs and knowledge in order to establish a foundation of certainty upon which to build his philosophy. By doubting everything that can be doubted, Descartes aimed to arrive at indubitable truths that could serve as a solid basis for his philosophical system.
"I think, therefore I am" is the first truth of which Descartes is certain. This statement, known as cogito ergo sum, demonstrates Descartes' method of doubt by acknowledging that even if all his perceptions are false, his ability to doubt and think proves his existence as a thinking being.
Short answer: Descartes' doubt was like WWI - the doubt to end all doubt. Only by doubting everything could Descartes hope to find anything that was certain (even if the only certainty is that nothing else is certain!).

Descartes found it impossible to doubt his own existence. The reason for this was that he felt that thoughts had to come from himself.
Descartes' concept of systematic doubt involves doubting everything that can be doubted in order to arrive at indubitable truths. By doubting the reliability of the senses, memory, and even the existence of an external world, Descartes sought to establish a foundation of knowledge based on clear and distinct ideas that could not be doubted. This method of doubt is a key component of his philosophical method known as Cartesian skepticism.
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.
He can not doubt that he thinks, therefore he exists.
That he is sentient ie that he thinks.
Descartes' theory of knowledge was to doubt all things and accept as knowledge the things that could not be doubted
Descartes hopes to find out what he can know for certain, without any doubt, about the world and nature.
Descartes' evil genius argument proposes that it is possible for an all-powerful deceptive entity (evil genius) to be manipulating our thoughts and perceptions, making it impossible for us to trust our senses and reasoning. This argument aims to show that doubt can be applied to all knowledge, except for the fact that one is doubting (cogito, ergo sum - I think, therefore I am).
he believed if you can doubt it, it must not exist.
Descartes aimed to prove that he could establish certain knowledge by doubting everything that could be doubted, ultimately leading to the famous conclusion "I think, therefore I am" as the foundation of his philosophy. He sought to find a firm foundation for knowledge that was beyond doubt.
