Answer:
Step-by-step explanation:
René Descartes' method of doubt, also known as the Cartesian method, was a systematic approach to philosophy and epistemology, designed to eliminate all belief in false or uncertain knowledge. The method was introduced in Descartes' famous work "Meditations on First Philosophy".
The purpose of the method of doubt was to establish a solid foundation for knowledge. Descartes was skeptical of the knowledge he had acquired through his senses and believed that it was necessary to cast doubt on all beliefs in order to find certain and indubitable knowledge.
In pursuing this method, Descartes made the skeptical argument that it is possible that an evil demon or other deceivers could be responsible for all of the false or uncertain knowledge that we have acquired through our senses. He used this argument to cast doubt on all of his beliefs, and only accepted as true those beliefs that could not be doubted.
The method of doubt ultimately showed that the only thing that can be known for certain is that the individual exists and thinks. Descartes famously wrote "Cogito, ergo sum" (I think, therefore I am), which became the foundational principle of his philosophy. He believed that this indubitable truth could serve as a starting point for the acquisition of further knowledge and that all other truths could be deduced from this principle.
In conclusion, Descartes' method of doubt was a systematic way of eliminating false or uncertain knowledge in order to find indubitable truths. The method showed that the only thing that can be known for certain is that the individual exists and thinks.
