Philosophy 201 Guidelines
Cogito ergo sum
Here in the Philosophy forum we will talk about all the "why" questions. We'll have conversations about the way in which philosophy and theology and religion interact with each other. Metaphysics, ontology, origins, truth? They're all fair game so jump right in and have some fun! But remember...play nice!

Genetic algorithms are too simple to be all-explanatory even within a physicalist framework.
Acquired falsifiable theories are built on a foundation of implicit knowing and knowing how.
No, that's not it. It's not primarily an empirically based question. We also assign plausibility and probability that aren't specifically tied to empirical evidence.
Unless it's the assumptions that make 'objective, testable knowledge' possible in the first place.
There is a concept called 'post-empirical science.' My point was that scientific speculation, and speculation generally, has not, is not and should not be fettered by what is considered 'empirically verifiable.'I'd like to put this point to rest once and for all. Not all knowledge is empirical knowledge.

We're talking about scientific claims that have been decided upon as true.
This an OK definition, but you have not provided an 'decisive truths' yet. All you and seer have mentioned is a few facts that would be in agreement as simply objective observations.
Still waiting . . .

till waiting for you to respond to the reference as cited instead of making fallible human assertions. Your claim that the Law of Non-Contradiction would only apply if we had the absolute knowledge of God.
Science and logic cannot prove the Law of Non-Contradiction.

Originally posted by seer View PostI did not use circular reasoning, the impossibility of a square circle or the sun existing and not existing at the same moment just demonstrates the LONC. But since you don't believe that the LONC is an absolute I wonder why you would find any problem with circular logic. Why? Based on what?
There is a difference between accepting the LONC because it is needed in order to have a rational discussion with another human being, and accepting that the LONC is "absolute". Some people may think it's absolute because they can't imagine doing without it, but that is merely an opinion, and I think the existence of paraconsistent logic shows that it isn't a very well informed opinion. Perhaps it's a very strongly held opinion, but not one that I'm obligated to go along with simply because I need to at least provisionally accept the LONC in order to have a discussion with them.
If "absolute" means "clearly obvious to me", then go ahead and call it absolute. Just don't expect to use that as the basis of a cogent argument for a supreme being.

Originally posted by Stoic View PostYou again make me wonder what you mean by "absolute". I think the LONC is based on the meaning of negation, and having a rational discussion in any language that includes negation (which includes all human languages, as far as I'm aware) implies at least provisional acceptance of the LONC. But the LONC is accepted without proof, because any attempt to prove it will be viciously circular, as you have just demonstrated. If we came across some space aliens who were more accepting of contradictions than we are (perhaps they are dialetheists), we would not be able to prove to them that contradictions are always false without begging the question.

Originally posted by seer View PostI have no problem using negation. They only way you have around this that I can see is that you have to accept, at least in theory, that true contradictions, like a square circle can exist.
And if you undermine the LONC, the very foundation of logic, why would circular reasoning be suspect? Throw it all out.
People used to think that this was the case for true contradictions, also; that if you allowed even one contradiction to be true, then anything could be proved. This is called the Principle of Explosion. But then logicians figured out ways around it, like denying the validity of disjunctive syllogism or disjunction introduction (see the article).
But you are in fact suggesting that true contradictions can exist. I have asked you a number of times Stoic to present a real world example of a true contradiction using paraconsistent. You have failed to do so.

Originally posted by Stoic View PostYes, you have to accept, at least in theory, that true contradictions can exist. You don't have to accept any particular contradiction as true, or even possibly true, and you don't have to provide an example of a true contradiction. You just have to accept in theory that true contradictions can exist.
If you allow circular reasoning, then anything can be proved. You can use circular reasoning to prove B, and then you can use circular reasoning to prove not-B. Or you can simply use circular reasoning to prove (B AND not-B).

I don't need to provide an example, due to a little thing called the Burden of Proof. You asserted that the LONC is absolute. I simply doubt your assertion.Atheism is the cult of death, the death of hope. The universe is doomed, you are doomed, the only thing that remains is to await your execution...

Originally posted by seer View PostHow do you distinguish between a true contradiction and a false contradiction? What is your criterion? Your standard?
And? You are already throwing out the fundamental corner stone of reasoning, the LONC. Why is non-circular logic sacrosanct?
See you have no real world example! And remember you too are making a claim - that true contradictions are possible.
