Are we all bound by a common moral code, or is right and wrong simply a matter of cultural perspective? Our comprehensive report delves into the age-old debate between universalism and relativism. It explores the philosophical, empirical, and practical arguments for a universal ethic—from Kant's rationalism to recent cross-cultural scientific studies—and dissects the most significant objections to the idea. We also reveal how the concept of universal morality, particularly through Natural Law, profoundly influenced the founding principles of the United States. Read the full essay to explore the foundations of a shared humanity and the enduring questions that define our moral landscape.
