Stars, Cells, and God | Aquinas’s Second Way

Reasons to Believe Podcast

Join Jeff Zweerink and Kyle Keltz as they discuss new discoveries taking place at the frontiers of science that have theological and philosophical implications, including the reality of God’s existence.

Modern scientists often dismiss Aquinas’s Five Ways as being outdated, irrelevant, or even invalid. However, when properly understood, the Five Ways show a remarkable similarity to how we think and approach science and they provide profound insight into explaining the universe. In this episode, astrophysicist Jeff Zweerink and philosopher Kyle Keltz discuss the philosophical background that led to Aquinas’s work—specifically in articulating the Second Way—and explore its relevance in light of scientists’ research to develop a quantum theory of gravity.
