Answer the question in 3 pages : Why does Descartes believe that even if the Dreaming Argument undermines our beliefs in the existence of the body and the external world, it does not undermine the truth of mathematical and logical beliefs? How does the evil genius/evil demon argument undermine these latter set of beliefs? What is the one thing that remains certain even if an evil demon exists and is running the world?

Answer The Question In 3 Pages Why Does Descartes Believe That Even I

René Descartes, often considered the father of modern philosophy, embarked on a profound quest to establish an indubitable foundation for knowledge. His methodological skepticism aimed to discard all beliefs that could be doubted, ultimately seeking those beliefs that are absolutely certain and indestructible. Central to his philosophy are the Dreaming Argument and the Evil Demon (or Genius) Argument, which serve as pivotal ways to challenge our beliefs about reality, particularly concerning our perceptions, the existence of the external world, and the certainty of mathematical and logical truths. Understanding why Descartes maintains that certain truths withstand these radical skeptical challenges involves examining the nature of doubt, the distinction between sensory and rational knowledge, and the implications of an omnipotent deceiver.

The Dreaming Argument and Its Limitations

Descartes introduces the Dreaming Argument in his "Meditations on First Philosophy" as a challenge to the reliability of sensory experience and, consequently, to beliefs about the external world. He asks: how can we be sure that our current experiences are not dreams? Since dreams often mimic reality convincingly, any sensory-based belief about the external world could be false. This skepticism casts doubt on empirical knowledge—our beliefs about objects, physical processes, and the environment—because these are primarily grounded in sensory perception.

However, Descartes asserts that while the Dreaming Argument undermines our trust in sensory-based beliefs, it does not affect certain rational truths. Mathematical and logical propositions, such as "2 + 2 = 4" or "a triangle's interior angles sum to 180 degrees," are immediate and clear. These truths are apprehended through reason alone and do not rely on sensory perception; they are necessary truths that are true independently of the physical world or our sensory experiences. Therefore, even if sensory beliefs are dubious, the certainty of mathematical and logical truths remains intact. They are not contingent upon an external world or sensory data but are rooted in the very nature of reason itself.

The Role of the Evil Genius/Demon in Undermining Beliefs

Descartes deepens his skepticism by hypothesizing the existence of an all-powerful, malicious "Evil Genius" or "Evil Demon" who systematically deceives us about the nature of reality. This hypothetical demon possesses the power to manipulate our perceptions and beliefs, causing us to believe in a physical world that does not exist, deceive us about mathematical truths, and alter our rational faculties. Under such deception, all beliefs about the external world, including mathematical and logical propositions, could be false.

However, Descartes recognizes that even under the influence of this deceiver, there is one indubitable truth: the very fact that he is thinking, doubting, or being deceived. The act of doubt or thought itself proves the existence of the thinker—this is captured in the famous dictum, "Cogito, ergo sum" ("I think, therefore I am"). This constitutes the cornerstone of Descartes’ philosophy: even if a demon deceives him about everything else, the very fact that he is being deceived demonstrates that he exists as a thinking entity. This indubitable insight remains certain regardless of any deception, thus surviving the most radical forms of skepticism.

Consequently, the "thinking self" emerges as the foundational certainty in Descartes' epistemology. While the demon can deceive him about the existence of physical objects, mathematical truths, or sensory experiences, it cannot deceive him about the fact that he is thinking. This self-awareness, not mediated by sensory or external validation, withstands even the most potent skeptical assaults.

The Preservation of Rational Certainty

From this analysis, we understand that Descartes’ skepticism about the external world and sensory-based knowledge does not threaten the certainty of rational truths. Mathematical and logical propositions are considered to be innate or deducible truths that are true by their very nature and are accessible through reason alone. These truths are necessary and universal, not contingent on the existence of an external reality. The fact that they are necessarily true means that they cannot be false, even under the influence of an evil demon.

Furthermore, Descartes uses the process of methodological doubt not as a destructive tool but as a clarifying one, stripping away uncertain beliefs to reveal those that are absolutely certain. The certainty of the "Cogito" is the bedrock upon which he aims to rebuild knowledge. Once he establishes his own existence as a thinking thing, he can then infer the existence of a non-deceptive God and re-establish the possibility of reliable perception and scientific knowledge. However, the key point is that the certainty of mathematical and logical truths remains unaffected by even the most extreme skeptical scenarios, including the existence of an evil demon.

Conclusion

In conclusion, Descartes’ philosophical project hinges on distinguishing between different kinds of knowledge and understanding the limits of skepticism. The Dreaming Argument exposes the fallibility of sensory-based beliefs about the external world but leaves the certainty of rational, mathematical, and logical truths untouched because they are grounded in reason itself. The Evil Demon Argument further challenges all beliefs, but even in this scenario, the fact that one is thinking remains undeniably true, serving as the foundation of certain knowledge. This insight allows Descartes to rebuild a secure epistemological framework, where reason and rational truths occupy the ultimate and indubitable position, unaffected by even the most radical skeptical doubts introduced by the Dreaming and Evil Demon arguments.
