Descartes’ method of radical doubt aims to strip away all unreliable beliefs, particularly those based on sensory perception, to find a foundation of certain knowledge. His skepticism towards the senses stems from their frequent errors, which demonstrate their fallibility. Examples such as optical illusions, the misinterpretation of pain, and the possibility of dreaming highlight how sensory experiences can deceive us, making it unreliable as a sole basis for understanding reality. Descartes recognizes that senses can be fooled, so he refuses to accept sensory data as definitive evidence of what is truly real. Instead, he searches for an indubitable foundation for knowledge that does not depend on sensory perception but on rational insight and logical certainty, such as the realization ‘I think, therefore I am’ (Cogito, ergo sum). This approach allows him to establish a secure starting point for philosophical inquiry, free from the errors of the senses.

René Descartes’ approach to understanding what constitutes reality is deeply rooted in his methodological skepticism. Instead of relying on sensory experience to determine what is real, Descartes embarked on a philosophical quest to find an undeniable foundation of certainty, fundamentally questioning the reliability of all perceptions that depend on our senses. His reasoning illustrates a critical philosophical stance: our senses, while often useful, can mislead us, leading to false beliefs and illusions. As highlighted in the first student response, optical illusions like rainbows or the distortions caused by optical refraction demonstrate that sensory perception is not infallible. Similarly, physiological states like illness can distort sensory input, and even everyday experiences, such as feeling pain in the absence of any external stimulus, reveal the fallibility of these perceptions.

Moreover, Descartes’ famous doubt extends to the possibility that all perceptions could be illusions or dreams, making even seemingly apparent physical reality unreliable. His doubt leads to his famous conclusion: “I think, therefore I am” (Cogito, ergo sum), asserting that the very act of doubting or thinking confirms his existence. This realization provides an indubitable starting point for knowledge, independent of the senses, which he considers capable of deception. This approach aims to reconstruct our understanding of reality on a rational, foundational level that is immune to sensory errors. By doing so, Descartes seeks to establish a secure basis for subsequent scientific and philosophical inquiry, free from the uncertainties inherent in sensory data.

However, critics argue that even rational certainty, such as the Cogito, might not fully account for the complexities of reality. The mind-body problem, for example, raises questions about how non-physical mental states relate to physical substances—an issue that Descartes himself struggled with. Despite this, his skepticism remains influential because it emphasizes the importance of rational insight over unreliable sensory impressions when determining what is truly real. Ultimately, Descartes does not simply accept sensory information because the potential for deception is too significant; instead, he prioritizes rational certainty to establish an unshakeable foundation for knowledge about reality.
