Aristotle's Physics: Nature, Motion & Change | Ep. 30 The TAC Podcast
The TAC Podcast
What can Aristotle teach us about the study of the natural world more than 2,000 years after he wrote the Physics? Unlike modern physics, Aristotle's study of nature begins not with equations, specialized experiments, or mathematical models, but with our ordinary experience of the world around us. Motion, change, time, causality, matter, and nature itself are realities we encounter constantly, yet rarely stop to examine. In this episode of "The TAC Podcast," Dr. John Finley and Dr. Chris Decaen explore the opening of Aristotle's Physics and ask why this ancient work remains foundational to the Western philosophical tradition. They discuss the difference between modern physics and the classical philosophy of nature, why Aristotle begins with what is most familiar to human experience, how knowledge moves from effects toward causes, and why understanding change ultimately requires an account of matter and form. The conversation also considers a larger question: Can scientific measurement ever replace philosophical reflection on what things actually are? From Aristotle's investigation of nature emerges a path toward some of philosophy's deepest questions, including human nature, causality, the soul, and ultimately the unmoved mover Aristotle identifies as the highest cause of the natural world.

About Podcast
Each week, senior members of the teaching faculty open a window into the intellectual life of the College through conversations rooted in the Great Books and the pursuit of first principles. Together, they explore the foundational questions that have shaped Western civilization.
Grounded in the liberal arts tradition, the podcast invites listeners into the same kind of thoughtful, rigorous dialogue that defines the classroom experience. From ancient mathematics and astronomy to philosophy, theology, and modern science, each episode seeks to understand the truth of things by returning to first principles.
Occasionally featuring guest scholars and educators, the show offers rich discussions on the Great Books, liberal education, and the enduring relevance of classical learning.
