Review Questions

• Explain how Descartes' concept of Cartesian doubt relates to the study of epistemology.
  • Descartes' method of Cartesian doubt, which involved systematically questioning all beliefs and knowledge, was a critical step in the development of epistemology, the study of the nature and scope of knowledge. By doubting the validity of all his existing beliefs, Descartes sought to establish a foundation of knowledge that was absolutely certain, which ultimately led him to the conclusion of his own existence as a thinking being ('I think, therefore I am'). This emphasis on the importance of reason and the systematic questioning of knowledge was a significant contribution to the field of epistemology and the broader Enlightenment period.
• Describe how Descartes' principle of mind-body dualism relates to the concept of skepticism.
  • Descartes' philosophical view of mind-body dualism, which posits the separation of the mind and body as distinct substances, had important implications for the development of skepticism. By establishing the mind as a non-physical, thinking substance that is separate from the physical body, Descartes opened the door to questions about the reliability of our senses and the nature of reality. This laid the groundwork for further skeptical inquiry, as philosophers grappled with the implications of the potential disconnect between the mind's perceptions and the external world. Descartes' dualism thus played a crucial role in the evolution of skeptical thought, which continued to challenge the certainty of human knowledge and experience.
• Analyze how Descartes' concept of 'Cogito Ergo Sum' ('I think, therefore I am') serves as the foundation for his philosophical system and its impact on epistemology and skepticism.
  • Descartes' foundational principle of 'Cogito Ergo Sum' ('I think, therefore I am') was a revolutionary idea that had a profound impact on the fields of epistemology and skepticism. By establishing the existence of the self as a thinking being as the only thing that can be known with absolute certainty, Descartes laid the groundwork for his philosophical system, which sought to build a new framework of knowledge based on reason and clear, distinct ideas. This emphasis on the primacy of the thinking self and the systematic questioning of all other beliefs was a key contribution to the development of modern epistemology, as it challenged traditional sources of knowledge and authority. Furthermore, Descartes' 'Cogito Ergo Sum' principle was a cornerstone of his skeptical approach, as it represented a foundational truth that could not be doubted, even in the face of systematic questioning. This laid the foundation for further skeptical inquiry and the ongoing debate about the nature and limits of human knowledge.
