Right, and Lionino would have probably returned and said something even more provocative, which is why it isn't worthwhile to defend. Or like says, th...
- Yep. :up: I think Lionino could be defended. After all, an inflammatory style is not against the rules on TPF. I think Lionino had a way of highligh...
- Hard to say. Presumably it is the set of ideas that spread internationally after George Floyd's death, ideas which are centered on a narrative of ra...
Yep. I think he wanted to be banned. But he was ultimately being anti-U.S., which is curious. He complained that "Burgerland" (the U.S.) exports "geor...
Interesting thread. Philosophy could be called highest because it is without presuppositions. But could it be called highest for a more substantive re...
Left = legacy media = $$. Right = grassroots media & free speech. Do a quick search on the fundraising and spending numbers from the left and the righ...
...And I want to say that an argument is supposed to answer the "why" of a conclusion. Inferential argumentation is an explanation for a proposition/c...
Similar to what I said earlier about the genus of discourse, some arguments are apparently neither valid nor invalid: Probably they are not "arguments...
These are interesting topics that Aristotle also takes up, but I don't think I'm being overly greedy in what I desire. I am not requiring a special ki...
- Yeah, you're giving me flashbacks to Flannel's thread. That was a really interesting post, and it presents an interesting attempt to bridge proposit...
Yes, that's my point. Tones thinks it is valid by definition, because any argument with inconsistent premises is (trivially) valid. Now the question a...
- Interesting, but it doesn't adjudicate the question. I don't expect the question to be adjudicated on these sorts of grounds (and Tones involves him...
- Good post. This is a very broad and pervasive topic that perhaps deserves its own thread someday. This is a source of the disagreement. I don't disa...
- Can you spell out your point for me? It looks to me like a good example of why a sentence is different from an argument. I don't think it is possibl...
Validity is a relationship between premises and conclusion. This is what I say is the common interpretation of your sources on validity: 1. Assume all...
I agree, but Tones is talking about assignment or inconsistency, not necessary falseness. A (formal-propositional) contradiction is necessarily false,...
Tones is interpreting English-language definitions of validity according to the material conditional, not merely the OP. He himself now recognizes thi...
- In short, it removes it. See: Lots of people are not paying attention to the differentiation of arguments for why the OP might be valid. Three optio...
The idea that it is a relationship already excludes your reading. If a relationship between A and B must be established, then one must know something ...
It's called paraphrase, and we both know you hold to the paraphrased proposition. You should be a lawyer given the way you constantly complain, nitpic...
Any argument with inconsistent premises is valid, according to Tones. Weird indeed. It requires a strained reading of the fine print of portions of de...
There is no question that he would reject your tendentious interpretation, which fully ignores the bolded sentence of Gensler's. Suppose you are on th...
Let's take the first: The question is whether we should read Gensler as presupposing that the premises are consistent. You want to say, "The premises ...
And that does not make the argument valid for Gensler, Enderton, SEP, or Wikipedia. But it does for you. Because you are leveraging an idiosyncratic n...
Here is Gensler speaking about validity in his introductory chapter: Here is Enderton: Here is SEP: Here is Wikipedia: @"TonesInDeepFreeze" wants to s...
But does logic really capture how these claims refute themselves? I don't think so. It merely defines a formal notion of contradiction and shows that ...
Validity in propositional logic involves a relativization of truth-values with respect to inference-relations. Inference-relations are held steady, an...
We could say with that if the conclusion flows from the premises then the argument is valid. 1. P?Q 2. P 3. ? Q 4. A?~A 5. A 6. ? B Now one could say ...
What you've done is imported the artificial truth-functionality of the material conditional into the consequence relation itself. You have contradicte...
Isn't that reductio? I would say that, like argument, contradiction also requires a kind of middle term, and is therefore never direct. For example: P...
Your "disjunctive syllogism" is different than my A?A, so in that sense, sure. You are effectively saying that A flows or follows from the contradicti...
- I added an edit to that post, which might help. My point about conditionals and arguments would also apply to "proves," "flows," etc. - Ergo: A?A A,...
I realize a lot of people like this claim, but I don't think it is right. You are confusing consequence or inference with identity. Even on a very for...
I'm not sure what post you are responding to, but there is of course a substantive issue here. It is the difference between rules-as-arbitrary and rul...
Right: the conclusion must flow from the premises. The premises must provide the aitia for the conclusion. A contradiction is not an aitia. As I argue...
- Good posts. :up: In cases of inconsistent premises what happens is that the person arguing arbitrarily makes use of some premises while conveniently...
- Why do you think dialetheism relates to the consequence relation? Presumably you think the LEM is tied to the consequence relation, and that dialeth...
I haven't seen anyone define any of the positions in a clear and non-vacuous way, much less go on to argue in favor of one or another. "There are mult...
I figured this would be an interesting thread. This is the standard set piece where Banno and Tones think logic is arbitrary symbol manipulation and o...
- I would suggest going back to this post and working out why you felt the need to effectively say, "Well, it's more complicated than my first post al...
You are the one who has assumed that all that is occurring in the video is "stimming," and that stimming is always connected with down-regulation. So ...
- So then play is merely down-regulating? That strikes me as patently false. I have been around autistic people. I don't interpret everything they do ...
