Cogito argument
The Cogito argument, coined by philosopher René Descartes, is best summarized by the phrase "I think, therefore I am" (Cogito, ergo sum). It asserts that the very act of thinking is proof of one's existence. Descartes reasoned that even if an external world or one’s senses are deceived, the undeniable reality is that the thinker exists while pondering these doubts. Thus, the ability to doubt or think proves that there is a self experiencing those thoughts. This foundational idea highlights consciousness as a core aspect of human existence and serves as a starting point for exploring knowledge and reality.
