Review Questions

• How does Descartes use methodological skepticism in Meditations on First Philosophy to establish foundational beliefs?
  • Descartes employs methodological skepticism by doubting all beliefs that could possibly be false or uncertain. He systematically questions sensory experiences and preconceived notions to identify what can be known for sure. This process leads him to conclude that while he can doubt everything else, he cannot doubt his own existence as a thinking being, encapsulated in his statement 'Cogito, ergo sum.' This establishes a secure foundation for his subsequent arguments in rationalism.
• Discuss the significance of clear and distinct perceptions in Descartes' argument for knowledge in Meditations on First Philosophy.
  • Clear and distinct perceptions play a crucial role in Descartes' epistemology as he posits them as the ultimate criteria for truth. He argues that whatever we perceive clearly and distinctly must be true, which becomes essential in proving God's existence and the reliability of human reason. By establishing this standard, Descartes aims to counter skepticism about knowledge and provide a rational basis for understanding reality.
• Evaluate how Meditations on First Philosophy contributes to the development of rationalism and its response to skepticism in modern philosophy.
  • Meditations on First Philosophy marks a pivotal moment in modern philosophy by laying down the foundations of rationalism. Descartes' systematic approach to doubting all beliefs challenged prevailing notions of knowledge rooted in empirical observation. His conclusions about the certainty of self-awareness and clear perceptions provide powerful counterarguments against skepticism. This text not only influenced later philosophers like Spinoza and Leibniz but also shifted philosophical inquiry towards reason as a central pillar for acquiring knowledge, shaping discussions that resonate throughout modern thought.
