Review Questions

• How did Descartes' method of doubt influence philosophical inquiry in relation to Plato's ideas?
  • Descartes' method of doubt encouraged a critical examination of beliefs to establish a more solid foundation for knowledge. This approach differed from Plato’s reliance on ideal forms as the ultimate truth. By doubting everything until something indubitable was found, Descartes shifted focus towards individual reasoning, creating a new paradigm in philosophical inquiry that paved the way for modern philosophy.
• Discuss how Cartesian Dualism contrasts with Plato's Theory of Forms in understanding reality.
  • Cartesian Dualism posits that the mind and body are distinct entities, whereas Plato's Theory of Forms suggests that non-physical (ideal) forms are the truest reality behind the physical world. Descartes emphasizes the importance of individual thought as a pathway to understanding existence, while Plato focuses on transcending the material world to grasp eternal truths. This contrast reflects a significant shift in thought from idealism to a more dualistic perspective on existence.
• Evaluate the impact of Descartes’ rationalism on subsequent philosophical developments after Plato.
  • Descartes’ rationalism marked a pivotal shift from Plato's idealistic framework to an emphasis on reason as a primary source of knowledge. This transition influenced subsequent philosophers such as Spinoza and Leibniz, who further developed rationalist thought. It also laid groundwork for empiricists like Locke and Hume to respond critically, leading to rich debates about the nature of knowledge, reality, and existence that have shaped modern Western philosophy profoundly.
