You're making a wrong assumption about Aristotelian logic. I can see why Bomb#20's example is not conclusive. It is in fact very easy to see that Aristotelian logic can prove Bomb#20's example valid....
Actually, mathematicians prove plenty of things that cannot be proven under AL. In the other thread, Bomb#20 gave a much simpler example than complex mathematics. In fact, CML is very intuitive to...
And then what? The derivations you're talking about are just wrong, as is the case with EFQ and ACQ for example.
There is as of today no formal method that does Aristotelian logic. You seem...
I'm absolutely certain it is not. But I wasn't trying to raise that issue. What I meant is that it's not the same if the correct logic is what you believe it is, or the correct logic is another logic...
I would refrain from making general rules here. People certainly have a trajectory and therefore behave in a way which is somewhat predictable. Yet, they live in a dynamic environment and are...
It would be unwarranted, though. We do not know whether there can be a human society without language. Is language like, say, morality? (so, the anwswer is negative). Or is it a technology, like...
How could they decide which logic is correct?! I have asked you for a justification that the definition of validity used in mathematical logic was correct, to no avail. There is no such...
That is not a contradiction between different areas of math. That is a philosophical disagreement between mathematicians. It is not the same. Moreover, those who argue against ¬¬P->P do not argue...
Could you give an example of those contradictions?[/QUOTE]
Sure. For example, "when some mathematicians argue in support of intuitionistic logic and argue against ¬¬P->P, whereas others disagree...
And animals. Ants and bees. All sorts.

Yes, by "inherent" here I meant that the capacity is understood to be part of human nature.
EB
Do as you see fit.
I'm absolutely certain it is very seriously wrong. However, I think that even a very seriously wrong logic may not have any apparent deleterious impact depending on how it...
The poll's question: Can using logic lead to ilogical and erromeous results?
The question is terminally messy.
So, yes, using logic can lead to erroneous results.
For example if the premises...
Reminder
Okay, so according to that, the question is: Is the capacity to tell whether an argument follows from premises part of human nature?
If you mean that, then I do not know.[/QUOTE]
OK, fair...
It's a poll, Johnny.
You're wrong again, on substance, Johnny.
The basic question has been spelled out: Do humans have an inherent capacity to decide that a conclusion follows necessarily...
What's wrong with them, do you think?

I had chosen not to reply. I was not taking part in this thread. But you chose to attack. Why?
The reason I chose not to reply was, precisely,...
If they're equivalent to this one, you don't need them, because you're already here.[/QUOTE]
Well, yes, but he might get to spend at least some of his time over there.
Pros and cons, that sort...
And what about actually casting a vote? :confused:
EB
Here are some of the people who can't decide between "Yes", "No", Don't know" and "Doesn't make sense".
What's wrong with them, do you think?
EB
Yes, you're being annoying. :glare:
We can be incapacitated. It's actually not true that humans have two legs and one nose because some people miss those. Do the British people speak English?...
The fact that their definition of validity is wrong shows mathematicians don't even understand logical validity. Mathematical logic is not even a restriction of logic. It's not logic at all.
EB
So the answer is you don't have the beginning of a clue.
EB
Stop the booze, John.
Let's not get delusional: there's no argument.
Only a simple question:
Alright, I guess we can close the thing. 100% yeses, not too bad. Thanks again to the voters....
Go on, do that.
