Re: Possible consequences of falsifying the principle of explosion?

Another way is sound deductive inference that requires all premises to be true. P1. If it rains the ground will be wet. P2. It rains. C. The ground is wet. Empirical counter-example (a.k.a FALSIFICATION) : https://www.youtube.com/watch?v=XjXvkIzUTtk Examining the argument + evidence holistically, w...

Re: Converting formal proofs to conform to sound deduction

(F ⊢ x) means ◻x I am going to remove myself from these discussions because you seem to be dogmatically doubling down on deduction as some absolute ideal for reasoning. A am observing that a lot of our disagreements boils down to the reductionism vs holism distinction. Q.E.D you reduce the logical ...

Re: The Contradiction of the Three Laws of Logic

So... what's the problem already? :roll: You tell me. What is your conception of a "problem" ? There's a lengthy list of cognitive biases and a nifty codex . Do you recognize any of those things as "problems"? Rather than throwing the burden of proof over the fence, try take it upon yourself from t...

Re: Transforming formal proof into sound deduction (greatly simplified)

I'm not sure how the so-called principle of explosion affects or could possibly affect mathematical theorems. Gödel maybe? EB It affects all formal systems. From a contradiction anything follows, which trivialises the notions of truth and falsity. https://en.wikipedia.org/wiki/Principle_of_explosio...

Re: Tarski Undefinability Theorem Reexamined

You have not convinced me that when we talk about category theory we are talking about the same thing. What would convince you? It's an abstract theory. In the abstract it says what it says - it does what it does. How you use it in practice is where it matters (and for fun - I could abstractly inte...

What do you think about universal mapping properties?
It's a formalization of Equifinality.

Re: Converting formal proofs to conform to sound deduction

Not picking a fight, just making an observation. Perhaps we have different "background frames" for the concept of isomorphism. What I mean by isomorphism as in functional equivalency. Different form - same function. I mean it in the sense where a transfer/translation function exists between two see...

Re: Converting formal proofs to conform to sound deduction

Really? So when I say "All cats are mammals" that's the same as saying cats are isomorphic to mammals? OK. so you are using "are" to mean "subset of". Cool. We can play that game up and down the layers of abstraction right until we get to the set of all sets. And then I am going to ask you.... This...

This is also perfectly valid, it is, however, unsound: Unsound deductive inference (false premise) (a) All dogs are office buildings (b) All office buildings have windows (c) Therefore all dogs have windows It's an Idiotic example because you have absolutely no way of introducing modal logic into y...

MTT the formal system will know when you are lying to it because it is already populated with axioms.
