I've been teaching philosophy for a decade, and I'm increasingly convinced that moral relativism—the idea that right and wrong are merely products of one's culture—is not just intellectually lazy but practically dangerous. Sure, we can acknowledge that customs vary, but when we say honor killings or slavery are 'true for them,' we abandon the very ground we need to condemn atrocities. Yet I also see how absolutism has fueled colonialism and dogmatism throughout history. Can we really have a universal morality without repeating the mistakes of the past, or is relativism the only humble option left?
