What’s the matter with moral fundamentalism?
Inspired by fellow philosopher Anthony Weston, I often ask my ethics students to create a diabolical toolkit of rules that would torpedo public dialogue. The idea here, I explain, is to spell out rules that would maximize the distance between “us” and “them,” ensuring that possibilities for cooperatively setting and achieving social goals—like peace, security, justice, public health, or sustainability—go forever unnoticed. For example, consider things like “prepare your comeback instead of listening” or “be angrier and talk louder than others.”
