Necessary Truths Exist

[henryp]

the problem is doing such would be special pleading. you would claim "the only truth is there is no truth" you are arbitrarily making the claim above its own criteria. you would also be begging the question. I imagine the conversation going like this "your logic is flawed because the only truth is that there is no truth" and of course you would be assuming exactly what you are trying to prove giving no reasons for it.

It's only a contradiction if they are in the same subset.

If the set of all rules contains a rule saying there are no rules in the subset[x], that is not a contradiction
vs.
a rule in subset[x] that says there are no rules in subset[x] is a contradiction

I'm not trying to prove anything other than it's not a contradiction as you claimed. It's just clever word play.

I could be misinterpreting things though. Are the people you're looking to disagree with trying to say there are no truths at all? Like 1+1 equaling 2 isn't a truth? If that's the case, I rescind my complaints, and would like to join in the calling of those people silly.
