Review Questions

• How does Descartes use skepticism in Meditations on First Philosophy to arrive at certainty?
  • In Meditations on First Philosophy, Descartes employs skepticism as a tool to question all beliefs and assumptions. He systematically doubts everything that can be doubted, including sensory perceptions and mathematical truths, until he reaches the conclusion that his own existence as a thinking being is undeniable. This method of radical doubt leads him to his famous assertion 'Cogito, ergo sum,' highlighting how skepticism can ultimately establish a firm foundation for knowledge.
• Discuss the significance of Cartesian dualism as presented in Descartes' Meditations and its impact on later philosophical thought.
  • Cartesian dualism is significant because it introduces the distinction between mind and body, suggesting they are separate entities that interact with one another. This concept challenges monistic views and raises questions about consciousness, identity, and the nature of reality. The impact on later philosophical thought includes debates over materialism versus idealism, influencing existentialists and phenomenologists who grapple with issues of existence and perception.
• Evaluate how Descartes' arguments in Meditations contribute to the ongoing debate between rationalism and empiricism in philosophy.
  • Descartes' Meditations contribute to the rationalism-empiricism debate by asserting that reason is the primary source of knowledge, contrasting with empiricist views that emphasize sensory experience. His method of systematic doubt demonstrates a reliance on rational thought to achieve certainty about knowledge, particularly through his conclusions about existence and God. This tension has led to significant philosophical discourse where later empiricists challenged Descartes’ assertions, emphasizing observation and experience as essential to understanding reality.
