Modern psychology can tell us how we behave or how our brains respond. But when it comes to purpose, it often falls silent. In this episode of Nexus, Phil and Sophia trace the historical disappearance of the final cause from psychology and argue that this absence has left the field fragmented and the person misunderstood. Turning to the Thomistic tradition, they suggest a way forward: not by rejecting science, but by reintegrating it with a philosophy of ends. This is an invitation to think more deeply about what it means to act, to choose, and to flourish.
