I think @"NotAristotle" is right insofar as the rule is ambiguous. There is no magical rule-book of logic that settles this issue, and in practice som...

Sure, and that's the same puzzle of the OP. I see your point. See:

- Of course we appeal to modus ponens. I asked why you think Susie's argument is valid. You gave an argument which you admitted is a presentation of t...

Do you know if you are appealing to the principle of explosion? Because I asked if you are "appealing to or presupposing the principle of explosion."
November 18, 2024 at 18:53
And so you are appealing to or presupposing the principle of explosion when you claim that Susie's argument is valid, are you not?
November 18, 2024 at 18:50
- Which is a presentation of the principle of explosion, is it not?
November 18, 2024 at 18:47
Why?
November 18, 2024 at 18:36
Susie gives an argument. Her premises are inconsistent. Is her argument valid? Do not presuppose the principle of explosion. A. Yes, Susie's argument ...

No, the issue is that if (2) is true then no one can presuppose (1), because the proposition in question is justifiable. The issue is that if (2) is t...

- No, you're wrong. I just had extended conversations with both of them. Tones is adamant that his claim does not presuppose explosion, and Michael is...

Well, in virtue of what do we have a duty to prevent immorality? Do we have a duty to perpetrators? Do we have a duty to victims? Do we have a duty to...

What I gave is a simple reductio: 1. Suppose, "We are brains in vats" can be true even if it is not possible to justify such a proposition 2. "We are ...
November 18, 2024 at 16:38
@"TonesInDeepFreeze" thinks that any argument with inconsistent premises is valid, and that the principle of explosion does not need to be presupposed...
November 18, 2024 at 16:33
Yes, you cherry-picked a highly tailored and dialogically misrepresentative quote in order to go out of your way in affirming an idea that no one was ...
November 18, 2024 at 06:44
You failed to understand the point I was making to Michael. I invite you again, for the third time, to go back and reckon with that point. If you can'...
November 18, 2024 at 06:30
You focused on something which no one contested. I am inviting you to focus on the point at issue. (Further, the reason NotAristotle is so confused is...
November 18, 2024 at 06:23
(Michael thinks your construal of validity is true in virtue of the principle of explosion. You explicitly say that it is not. You are obviously disag...
November 18, 2024 at 06:15
"If the premises are inconsistent then the argument is valid by definition," does not mean that the definition of validity is equivalent to the premis...
November 18, 2024 at 06:11
Here is what Michael said: NotAristotle: Tones' claim that inconsistent premises make an argument valid by definition seems strange to me. Michael: It...
November 18, 2024 at 06:08
Well, if your strange interpretation of your definition is not based on explosion, then we are back to square one, and it is simply wrong. "If the pre...

Did you see the colon at the end of that sentence?
November 18, 2024 at 05:47
It only "entails" it because it has presupposed it. Else you do disagree with Michael, who thinks that your construal of your definition is nothing ot...
November 18, 2024 at 05:43
Your interpretation of your definition presupposes explosion. So you would say that someone who does not understand the principle of explosion can app...

I would say that cultures interact in much the same way individuals do. In both cases there are things like exchange, mutual cooperation, conflict, ar...
November 18, 2024 at 05:27
That's fine if you want to say that the strange way you want to apply your definition is based on explosion, but this is a new claim. Earlier in the t...
November 18, 2024 at 05:12
The simplest answer here is that (3) is false. The second answer is that even if we grant (3), it then follows that (3) is not unjustifiable. That is,...
November 18, 2024 at 04:52
The names appear, but where is the claim that they are realists? To take an example at random: Mackie. Here is what your quote says about Mackie: How ...
November 18, 2024 at 04:19
"Unjustified" and "unjustifiable" are two different things. Michael's post would be entirely innocuous if we misread "unjustified" for "unjustifiable,...
November 17, 2024 at 21:43
- You quoted the word "unjustified" in response to a quote from Michael that does not contain that word. Instead it contains the word "unjustifiable."...

- If Banno is a realist who fits your characterization then that would be exceedingly helpful. If he had better reading comprehension his affirmation ...
November 17, 2024 at 21:33
I asked you for an example of a realist who holds to your misrepresentation. You didn't give one. If you did, then what is his/her name?
November 17, 2024 at 21:29
You fished out a single sentence in an SEP article? Who cares? Find a new god to put your faith in. I am asking about realists, not SEP. You need to s...
November 17, 2024 at 21:27
- This has already been explained to you. (Your contention that argument 2 cannot ever exist without argument 1 is magical, ad hoc thinking. There is ...
November 17, 2024 at 21:24
I am going to limit myself to serious interlocutors.
November 17, 2024 at 21:18
- All I've asked is for you to give me an example of a realist who holds to your strange version of realism. You have failed to do that for many posts...
November 17, 2024 at 21:16
We have a whole thread on this idea:
November 17, 2024 at 21:12
- So you think it is literally impossible to give argument 2 without implying argument 1? This is dumb beyond belief.
November 17, 2024 at 20:59
- I don't know of any realists who believe in unknowable truths. Apparently you don't either. The problem with IEP is that it conflates "global skepti...
November 17, 2024 at 20:58
- This shouldn't be so hard. Argument 1: Argument 2: Two different arguments. You want to claim that argument 2 is an enthymeme of argument 1. But it ...
November 17, 2024 at 20:41
No, they are two different arguments. One involves inferential reasoning and the other does not.
November 17, 2024 at 20:24
These are two different arguments, and the validity of the first does not ensure the validity of the second.
November 17, 2024 at 20:18
- Maybe you should try to find a realist who lines up with your (mis)representation.
November 17, 2024 at 20:15
- Seems like you're arguing against strawmen again. You impute some strange doctrine to realists, and when asked what realists hold this strange doctr...
November 17, 2024 at 20:12
- The difference between an argument from the definition of validity and an argument from explosion has been explained multiple times throughout this ...
November 17, 2024 at 19:33
<A thesis which is unconfirmable/unjustifiable is not a real thesis> Realists and anti-realists agree with this proposition. You are manufacturing a d...
November 17, 2024 at 19:26
That doesn't help. Your argument rides on the vagueness of that word. Consider: You might say that there is a difference between physical possibility ...

What do you mean by "sufficiently"?
