Across history, cultures, and continents, humanity has asked the same enduring questions: How should we treat one another? What does a just life require? How can we live together despite profound differences? In 4 CORE: The Universal Teachings of Humanity’s Wisdom Traditions , Michael Simon Baker explores a striking and often overlooked truth: beneath the world’s diverse religions and moral philosophies lies a shared ethical foundation. Drawing from Judaism, Christianity, Islam, Buddhism, Hinduism, Sikhism, Mormonism, and other wisdom traditions, 4 CORE identifies four core teachings that appear again and again—expressed in different symbols, stories, and languages, yet remarkably consistent in meaning: • Reciprocity • Compassion • Justice • Humility Written in clear, accessible prose, 4 CORE bridges scholarship and lived experience, offering readers a framework for ethical reflection that is both timeless and urgently relevant. Rather than arguing for a single belief system, the book invites dialogue—showing how shared values can serve as a foundation for peace, cooperation, and human flourishing in an increasingly divided world. 4 CORE is ideal for readers interested in comparative religion, ethics, interfaith dialogue, philosophy, and the search for common ground across belief systems.
