Morality You believe it was true, but you could be mistaken — Janus
I know I shouldn't address more than one thing because the other will be overlooked, but I can't bypass this. As a response to my example of a common way to use the concept of truth, your response shows that
even you, as someone forwarding a consensus theory of truth, do not actually use the word "true" to refer to a consensus.
How do we know this? Well, because saying "You believe it was true," in response to the example, would make absolutely no sense if you were referring to something that a consensus of people are doing. If the scenario is to write down whether something is true or false that only that individual can know, then obviously it's not a question of whether a consensus of people is doing/saying something.
The whole point of the example is to show that if "true" refers to something that a consensus is doing, then no sense can be made of "true" in the context I presented. But you seem to have made sense of it just fine. So you're not actually using "true," intuitively, to refer to something a consensus is doing.
Now maybe you're not actually forwarding a consensus theory of truth, but you're doing the old "A consensus that P is true makes it more likely that P is true," but in that case a consensus that P is true isn't identical to what it is for P to be true, so the fact that there's a consensus about some moral stance wouldn't amount to that moral stance being true by virtue of the consensus. In other words, what it would "mean" for a moral stance to be true wouldn't be identical to there being a consensus on the stance. What it would "mean" for a consensus to be true would have to be something aside from that. Well,
what would it be aside from that?
