In this episode, we delve into secularism not merely as a rejection of religion, but as a proactive ethical framework grounded in values like truth, compassion, equality, and freedom. Drawing from 21 Lessons for the 21st Century by Yuval Noah Harari, we explore how secularism aspires to guide moral decision-making through reason and empathy, while also grappling with its own challenges—including the risk of dogmatism and blind spots in the face of technological change. We reflect on historical missteps and examine how secular movements can remain self-critical and ethically resilient in a rapidly evolving world.
