About this episode

David Lahti and Michael Weisberg discuss the limitations of science in understanding meaning and morality.

In today’s episode, our speakers discuss this question: Is science the only reliable tool for understanding the world? Or for questions about meaning, morality, and ultimate purpose, do we need something more? You’ll hear from David Lahti, a biologist at Queens College, and Michael Weisberg, a philosopher at Penn. In this conversation, they explore the limits of scientific knowledge, how evolution intersects with questions of faith and suffering, and how their Christian and agnostic worldviews help them make sense of the difference between knowledge and faith. This forum was held at Penn in April 2026. Thank you to the student planning team for making this event possible. Find additional resources and quotes on the podcast episode page here .
