Why ‘Is’ Must Entail ‘Ought’

Abstract

I argue below for the view that non-moral truths entail moral ones. I first argue that moral claims do have truth values which are objectively true or false. I then argue that this objectivism does not entail non-relativism. I produce a simple possible worlds argument for the entailment view. I then give some examples where p entails q but many intelligent people have thought it does not, and where it does not, but many intelligent people have thought that it does. I also try to evaluate a somewhat neglected argument by Hume. In the final section, I further consider some moral and meta-moral opinions.
