Like you I am not enamoured with a simple division into ontic and epistemic versions of idealism.
July 23, 2024 at 23:46
A bit more on dialectic. A contradiction leads to explosion, as explained. Dialectic bases itself on contradiction, where "opposite sides" lead to a "...
July 23, 2024 at 23:45
Cheers. Might leave the idealism line where it is, unless it becomes salient. Except that I will point out that the argument above applies to ontic id...
July 23, 2024 at 23:16
This was perhaps partially answered by the stuff about dialectic. My worry is that @"Wayfarer" argues for what he calls epistemic idealism when talkin...

We could do that again, but it's sunny... :wink: Long ago, in a previous forum, there was a long debate concerning the chairs at the end of the univer...

The result of contradiction in classical logic is not just vague - it's quite literally anything. (p ^ ~p)?q. From a contradiction, anything goes. Tha...

While dialectic has a certain appeal, I'm not as enamoured by it as you. I see two major issues. First, and most obviously, in classical logic asserti...
July 23, 2024 at 00:27
Logic isn't a replacement for natural languages. Nor is it a set of rules for how one ought construct arguments. This was part of the subject of my th...
July 22, 2024 at 23:40
Cheers. I am versed in anglo philosophy, with its emphasis on critique. It's not sufficient to learn about Buddhism or scientism, they must also be su...
July 22, 2024 at 01:29
Take this as granted. We can grant the point that we only know things with our minds. Reality is just what is the case. It is neither subjective nor o...
July 20, 2024 at 23:56
I admire @"Wayfarer"'s work, and that he and I agree on a great many things. In particular we both have a distrust of scientism, as well as the sort o...
July 20, 2024 at 23:41
Reality "exists independently of any particular mind" yet " has an inextricably mental aspect". Again, you mix two quite different things - the world,...

Here: " ...it is empirically true that the Universe exists independently of any particular mind." yet "...its existence is inextricably bound by and t...

He wants his cake and to eat it.

Where? Citation?
July 20, 2024 at 21:34
One might even say that the latter has little if anything to do with the former - that how things are is a different type of question to what we shoul...

July 20, 2024 at 00:11
Sure, all that. You want your cake and to eat it. On the one hand there is a world that is as it is 'independent' of us. On the other, what we say, th...

Remember this?

Prove RAA without MT? Interesting problem.
July 18, 2024 at 02:51
:lol: I give in.
July 18, 2024 at 02:35
OK. Much clearer Thanks. (2) amounts to 2. ~(b^~b)
July 18, 2024 at 02:34
Nope. Straight RAA does not require the "and elimination". It's an additional step when there are multiple assumptions.
July 18, 2024 at 02:25
Modus Ponens is ???, ?, ? ?. Not seeing it in 4.
July 18, 2024 at 02:24
So, what is a "direct proof"? I gather you think using MT is direct, but RAA isn't? What's the distinction here? While you are there, what does "FALSE...
July 18, 2024 at 02:19
What does "depends on" do here? Modus Tollens: ???, ~? ? ~? RAA: ??(?^~?) ? ~? Both are equally useable rules of inference.
July 18, 2024 at 02:17
And yet your claim that Reductio is invalid is just wrong.
July 18, 2024 at 02:09
The grain of truth in @"Leontiskos"' position is that reductio arguments need to be used with care. If we have a bunch of assumptions that lead to a f...
July 18, 2024 at 01:50
So here's the apparent problem: A, A?¬B?B ? ¬A A, A?¬B?B ? A It seems we can infer both A and ~A from the same thing. But that's because the two assum...
July 18, 2024 at 01:07
I don't see where I require anything like that in that post. After all, it's your post. It might help if you explained what FALSE is. As it stands, I ...
July 18, 2024 at 00:56
:grin: Presumably that's TRUE? Or is it 'TRUE'?
July 18, 2024 at 00:50
Well, first, ?,? ??^~?? (??~?) ^ (??~?) is nonsense. I stuffed up. Am I allowed to edit it? :wink: It should be (?^?) ??^~?? (??~?) ^ (??~?)
July 18, 2024 at 00:41
:lol: I think you have here managed to set out Leo's confusion far more clearly than has Leo. Can you see the answer?
July 18, 2024 at 00:32
If ¬(B?¬B) is true, as it must be, then this is not a valid use of modus tollens. Again, as i pointed out previously, you are comparing two very diffe...
July 18, 2024 at 00:26
The post does not show that I said I 'preferred the reductio to the modus tollens". And what I am after is a straight forward explanation of what "FAL...
July 18, 2024 at 00:15
Rubbish. Leo, what is "FALSE"?
July 17, 2024 at 23:46
It doesn't. Explained last time you made this claim... Oh, and what is "FALSE"?
July 17, 2024 at 23:40
I'm glad you followed this.
July 17, 2024 at 23:37
, what is "FALSE"? It's your term. This conversation is increasingly inane. Again, I seem to have reduced you to reciting gobbledygook.
July 17, 2024 at 23:28
Ok, Presenting a statement that someone has not made is not presenting an interpretation. :roll: Quite so. So what? It remains that RAA is a valid inf...
July 17, 2024 at 23:02
What is the supposed difference between "false" and "FALSE"?
July 17, 2024 at 22:47
Neither do I. This distinction between false and FALSE is not my doing. It seems to be another case of Leontiskos confabulating arguments on the part ...
July 17, 2024 at 22:32
And even if they were right, the conclusion does not obviously follow - indeed, it is very unclear what the structure of the argument is. SO I supose ...

Hello, creative. How are the fish hooks? It exactly does not depend on the values given to the variables. That's kinda the point of using variables - ...
July 16, 2024 at 23:51
Why not? I'm not seeing the issue here.
July 16, 2024 at 22:53
?¬(a?(b?¬b)) would be "It is necessarily not the case that A implies a contradiction"
July 16, 2024 at 22:42
Isn't it something like that "if it is not possible that A implies a contradiction, then A is necessarily true"? Or "If in no possible world A implies...
July 16, 2024 at 21:53
Yep. I gather you worked through this? Nice. Leo does that sort of thing - claims you have said something you haven't, if it suits his purposes.
July 16, 2024 at 21:30
Again, no. https://i.ibb.co/tY3PBHs/Pasted-Graphic-1.png F's all the way down.
