René Descartes was a French philosopher, mathematician, and scientist. Formally known as the father of modern day philosophy.
Descartes trusted that oneself is the main clear truth, and the second apparent truth would be the body he trusted that the brain and body where mutually dependent to each other, otherwise called dualism. Despite the solidarity of the brain and body, they both have their optimal capacities. Through the mind Descartes says it ought to be utilized to recognize the things that are sure. The third evident truth was the presence of the material world. He trusted that the brain was a piece of the non-material world and the body was a piece of the material world.
His first celebrated famous principle was “Cogito ergo sum” which implies I think therefore I am. Despite the fact that the mind and body are physically together, the brain and body are free and serve their own capacities. He was persuaded that with a specific end goal to dissect, explore and build up our own fact we should utilize our own mind and thinking capacities.
