C is true if and only if "You ought to get what you want" is true.Not really. I'm arguing that oughts are a valid conclusion to certain syllogisms.
P1: You want X. (E.g., to start a car)
P2: It is necessary to turn the key
C: You ought to turn the key
The ought follows. But it follows from a subjective premise -- wanting. Given "you want"; given "it is necessary"; "you ought".
That premise isn't subjective. It is an objective fact that I want chocolate ice cream right now.The ought follows. But it follows from a subjective premise -- wanting. Given "you want"; given "it is necessary"; "you ought".
Now I'm afraid you just aren't making sense to me. Premises and conclusions are just alleged facts. You're presenting the justification for the conclusion with the premises, and you aren't presenting the justification for the premises. That's the only difference.Oughts are justified in a conclusion if the premises are true. I'd argue that oughts are NOT justified in a premise. It may be true that a premise in this syllogism is from an ought in the conclusion of some preceding syllogism.
