Chapter 5a

Anchors Away

First Principles of Philosophy, Part One — Descartes, Hume, Kant

Watch on YouTube

Overview

Chapter 5a sets course by examining the three great 'anchors' of Western modern philosophy: Descartes, Hume, and Kant. Each philosopher responds to a crisis of knowledge and attempts to establish firm 'first principles.' Dr. Bannon frames this through the metaphor of 'anchoring' — what do we tie our discourse to so that it doesn't drift into meaninglessness?

Key Examples & Analogies

Descartes and The Matrix

The Matrix poses the ultimate Cartesian question: what if everything you perceive is a simulation? Descartes asked this before cinema existed, via the 'evil demon' hypothesis. His answer — 'even if I'm deceived, I must exist to be deceived' — is the Cogito.

Galileo's Challenge to Descartes

Descartes grew up believing Aristotelian science — that the Earth was the center of the universe. Then Galileo's evidence demolished this. Suddenly nearly everything Descartes had been taught was false. His response was radical skepticism: start over from the most indubitable point.

  2. What is the Cogito ('I think, therefore I am')? Why does Descartes consider it his first principle?
  3. What is Hume's 'bundle theory' of the self? How does it challenge our ordinary sense of personal identity?
  4. What does Kant mean by the 'thing in itself' (Ding an sich)? Why does he say we can never know it directly?
  5. What is a MetaNarrative? Why does postmodern philosophy critique metanarratives?
