After further reading Descartes’ work and exploring his philosophical views his first principle “Cogito Ergo Sum” (“I think, therefore I am”) has a much deeper meaning but yet simple in a way as well. After going over terms such as perception, perceiving, and irrefutable truths Descartes’ principle refers to his way of deeming whether something is really an irrefutable truth or a doubt through perception as well as intuition. The principle itself as well as his work states the senses can not be trusted since they can trick us but they are irrefutable since it’s by intuition our senses act/sense a certain thing. This intuition is immediate knowledge of a thing rather than reasoning. Thinking is intuitive to Descartes, it’s what makes a huge part of his personality and character due to this intuition he/his existence is irrefutable.
