In this engaging conversation, James Robert Brown, a philosophy professor at the University of Toronto, delves into the philosophical intersections of mathematics and ethics. He explores the intricate Continuum Hypothesis, challenging traditional views of infinities. The discussion highlights moral realism without the need for a deity and debates the validity of mathematical truths like '2+2=5.' Brown also navigates the complexities of free will in a deterministic universe, prompting listeners to ponder the nature of mathematical and ethical understanding.

Episode notes
INSIGHT

Thick vs. Thin Concepts

  • Thick concepts are simultaneously factual and evaluative, combining descriptive and normative aspects.
  • Examples include "brave," "healthy," and "charming," unlike thin concepts like "good" or "red."
INSIGHT

Thick Concepts in Math/Physics

  • Math and physics concepts can intertwine to form thick concepts, similar to thick ethical concepts.
  • This happens when mathematical models become internalized and fused with physical phenomena, like acceleration and second derivatives.
ANECDOTE

Freiling's Dart Experiment

  • Chris Freiling's thought experiment involving dart throws at the real number line seemingly refutes the continuum hypothesis.
  • This involves thick concepts of probability and randomness, intertwining physical intuition with mathematical formalism.
