The following quotation from Discourse on Method presents the four precepts that characterize the Method itself:
The first was never to accept anything for true which I did not clearly know to be such; that is to say, carefully to avoid precipitancy and prejudice, and to comprise nothing more in my judgment than what was presented to my mind so clearly and distinctly as to exclude all ground of doubt.
The second, to divide each of the difficulties under examination into as many parts as possible, and as might be necessary for its adequate solution.
The third, to conduct my thoughts in such order that, by commencing with objects the simplest and easiest to know, I might ascend by little and little, and, as it were, step by step, to the knowledge of the more complex; assigning in thought a certain order even to those objects which in their own nature do not stand in a relation of antecedence and sequence.
And the last, in every case to make enumerations so complete, and reviews so general, that I might be assured that nothing was omitted. By clear and distinct he suggests the evidence of the senses. The enumerations have in time developed into many forms. He suggested drawing boxes on a paper, and connecting them. This idea has led to a multitude of graphic thinking aids that we use today.
ReferencesDescartes' four rules were: 1) Never accept anything as true if there is any doubt; 2) Divide each problem into smaller parts to better solve them; 3) Think clearly and systematically; 4) Review and verify the conclusions reached.
Descartes believed that the senses are not to be trusted because they can sometimes deceive us. He argued that illusions, dreams, and other sensory experiences can lead us to false perceptions of reality. Since our senses can be unreliable, Descartes advocated for relying on reason and intellect to arrive at truth.
Descartes believed that truth could be determined through reasoning and skepticism. He emphasized the use of doubt as a method to arrive at clear and distinct ideas that could be considered true beyond any doubt. This approach led to his famous statement "I think, therefore I am" as the foundation for knowledge.
Descartes suggested the method of universal doubt as a way to arrive at certain knowledge. He proposed doubting everything that could be doubted in order to find a foundation of truth that is indubitable. This led him to his famous conclusion: "I think, therefore I am."
Descartes suggested the idea of doubt as a method for discovering truth. He proposed systematically doubting all beliefs that could be called into question, in order to arrive at indubitable knowledge. This method was intended to establish a foundation of certainty in knowledge, famously expressed in his statement "I think, therefore I am."
"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.

Descartes believed that the truth must be indubitable because doubting leads to answers. The only thing he perceived to be certain was his own existence.
Descartes and Bacon both advocated for skepticism and looking for the truth in a rational fashion. They both had methods of finding the truth in a logically ordered fashion that incorporated reasonable doubt.
That he existed.
Galileo Galilei was a Renaissance scientist who believed that truth was a standard to uphold. He advocated for the use of empirical evidence and observation to support scientific theories, even in the face of opposition from the Catholic Church.
Descartes
Descartes said that after he denied that he existed and came to the conclusion that he existed because he thinks, therefore he is real and exists.

Father Of Modern Philosophy.
Descartes famously stated, "Cogito, ergo sum" or "I think, therefore I am." This means that the one truth he can be sure of is his own existence as a thinking being, because the act of doubting or thinking proves that he must exist in some form.
