The correct answer and explanation is:
The correct answer is C: Through the recognition of self-evident truths, starting with his own existence.
René Descartes, in his work Meditations on First Philosophy, introduces the “evil genius” hypothesis to challenge everything he believes to be true. He imagines that a powerful and deceitful being could be manipulating his perceptions, making him doubt the existence of the external world, the reliability of his senses, and even the truths of mathematics. This is a radical form of skepticism that casts doubt on all forms of knowledge.
However, Descartes ultimately finds a way to resolve this doubt. He realizes that even if he is being deceived by an evil genius, there must still be something that is being deceived. This leads him to his famous conclusion, “Cogito, ergo sum” (“I think, therefore I am”). The act of doubting, thinking, or being deceived implies the existence of the thinker. No matter how much the evil genius tries to deceive him, Descartes cannot doubt that he exists as a thinking being. This recognition of his own existence as a thinking subject is a self-evident truth that cannot be undermined by skepticism.
From this foundation, Descartes argues that certain truths, such as the existence of the self, are indubitable. The recognition of one’s own existence as a thinking being provides a secure starting point for rebuilding knowledge. From this point, Descartes can then move forward to prove the existence of God and, subsequently, the reliability of clear and distinct perceptions. Therefore, the evil genius hypothesis, while initially casting doubt on everything, ultimately leads Descartes to affirm the certainty of his own existence and build a more secure epistemological foundation.
