True premises are not sufficient to establish soundness.Leontiskos wrote: ↑August 10th, 2021, 7:37 pmDo you even know what soundness is? It refers to the truth of premises, which is independent from inferential validity. The whole point of classical validity is that, given the truth of the premise or premises, the conclusion is true - whatever anyone thinks about it. This business of an obligation to accept the conclusion is an entirely irrelevant distraction. And I don't understand why you're banging on about it.Peter Holmes wrote: ↑August 8th, 2021, 9:28 amDo you even know what soundness is? Again, we are not talking about someone who accepts or rejects an argument. We are talking about someone who admits that an argument is sound and then rejects the conclusion. This is contrary to our obligation to truth.Leontiskos wrote: ↑August 2nd, 2021, 10:25 pmSound or obligatory arguments are always person-specific. If you are able to present an argument to your interlocutor that they believe to be sound, then they must accept the conclusion. That is, they are obliged to accept the conclusion. This is the relevance of the three conditionals I gave above. Each of them illustrate the nature of the obligatory inference. Again, the punch-line is that if you believe an argument is sound then you have an obligation to believe it.QED. You're free to accept or reject my argument. There's no obligation. And this is all a red herring anyway.
So what's an example? What you are doing right now is an example. You are trying to convince me that morality is not objective. All you are trying to do is present an argument that I agree is sound. You are not trying to convince me that I must accept sound arguments. If we get to the end of this and I say, "Well, I accept that all of the premises of your argument are true, and I also accept that all of your inferential reasoning is valid, but I still reject your conclusion," what would you say? You certainly would not go on arguing. You might say that I am intellectually dishonest, or that I am engaging in bad faith, or that I am not a real philosopher, etc. At root I would be failing my obligation accept truth where it is found. To accept an argument as sound and to reject its conclusion is to fail one's obligation to truth, and the very fact that you are engaging with me presupposes this obligation. If you didn't think I had an obligation to accept sound arguments you would stop engaging immediately.

Those are things you learn on the first day of Philosophy 101. Ergo, you haven't completed the first day of Philosophy 101.
I don't know how to argue with people who don't understand these fundamental concepts of philosophy, and therefore I'm not going to.
