Classical logic is a product of its arbitrarily chosen axioms.
Read my introduction again. I don't talk about "Classical logic" at all.

Re: Why still no science of logic?

essentially Aristotle, is sort of arbitrary Precisely! Have you heard of this theorem ? In mathematical logic, Diaconescu's theorem, or the Goodman–Myhill theorem, states that the full axiom of choice is sufficient to derive the law of the excluded middle, or restricted forms of it, in constructive...

Re: Individualism vs. Collectivism

https://www.theobjectivestandard.com/issues/2012-spring/individualism-collectivism/ The fundamental political conflict in America today is, as it has been for a century, individualism vs. collectivism. I doubt that very much. What is definitely for all to see is that first citizens have more freedom...

Re: Legal or Illegal: Is there a Difference?

If you can't get rid of Trump through democratic process, then you deserve to have Trump.
Think also of what to replace Trump with. There is always worse, as a cursory look at history and at the rest of the world could tell you.

Re: Rationalism v. empiricism

You think therefore you are?? I think what your mate said was: I think therefore I am. Changed it to. I think, I am. Then decided to say I think I am. And promptly died in the fireplace. So much for Rene. LOL. You didn't kept the pretence very long, did you? Nothing intelligent to say, therefore......

Re: Why still no science of logic?

" Logic as objective performance and manifest capability of human beings ". See? Nothing like a collection of axioms and inference rules. And I would prefer not to have to repeat myself. EB You are necessarily implying that we should study logic from a behaviourist perspective, but in order to desc...

Re: Why still no science of logic?

If we accept that in general, a deductive system is a collection of axioms and inference rules then the distinction drawn by Speakpigeon between Mathmatics and Logic is simply a distinction between the set of axioms and inference rules chosen. No. You didn't read my introduction. So, let me repeat ...

Re: Why still no science of logic?

Most people, at least those not terminally biased by a training in mathematical logic, would agree on the validity of the Modus Ponens, on the validity of Aristotle's syllogisms, on the validity of de Morgan's laws, etc. I think there are at least 50 logical laws that most people would agree on and...

Re: Why still no science of logic?

I think there are at least 50 logical laws that most people would agree on and they are not going to go away just because you say "not objective" or something. But the 'laws' of logic do go away if you just ignore them, or tweak the context. Very much unlike gravity. What you seem to call 'laws' a ...

Re: Rationalism v. empiricism

Without observation of empirical reality, reason almost immediately leads to falsehoods and idols of the mind. Sure, since your own mind is an empirical fact. And without rationality, empiricism definitely leads to "falsehoods and idols". Once you get that we are all ultimately empiricists. I'm not...

Rationalism v. empiricism

The difference between rationalism and empiricism is in the method of proof. Empiricism requires, by the conventional definition and usual understanding of the term, that the proof of your claim be an observation of the material world. Rationalism requires instead that the proof of your claim be an ...

Re: Justified true belief: knowledge and the myth of propositions

The problem of induction - that the future need not be like the past - doesn't affect the way things are now: the earth does orbit the sun - from which we can deduce true conclusions. You are assuming the conclusion. Affirming the consequent. The question is what are the conditions of propositional...

Re: Justified true belief: knowledge and the myth of propositions

The Gettier problem is that some cases of justified true belief don't amount to knowledge, so the JTB definition is inadequate. But I suggest that Gettier-cases really demonstrate the muddle caused by the myth of propositions. I know that my cat sits on the sofa. I know that p. That si, I know that...

Re: Why I lost respect for Aristotle

It makes very, very, very little sense for you to assess as you do Aristotle's potential merits against today's standards. If it was possible for you to prove that you would have done better than Aristotle had you been born in his time, you would have had a point. But you can't do that. The only way...
