“In general, those who advertise themselves as having superior moral judgment or unique access to moral truth need to be looked at askance. Not infrequently there is great advantage—in money, sex, power, and self-esteem—in setting oneself up as a moral authority. The rest of us can easily be exploited when we acquiesce in these authoritative claims. Scam artists aplenty proclaim themselves as moral gurus, willing to tell the rest of us how our conscience should behave. They can seem authoritative because they are especially charismatic or especially spiritual or especially firm in their convictions.”
