Bob and Alice Neither Bob nor Alice are philosophers, so they do not articulate their metaethical beliefs philosophically. Nonetheless, they have relatively sophisticated outlooks on moral thought. Bob believes that moral truths are objective, and you can be right and wrong on your thinking about morality. Killing is generally wrong is true in much the same way as it’s true the sun will rise tomorrow. If Bob became a philosopher, he’d probably decide that his metaethical beliefs are best captured by a strong form realism.
What about Charlie, who thinks that moral claims are objectively true, and it just so happens that they're the same as Charlie's very potent feelings?
