Logic doesn't work? (debate help)

[Saurencaerthai]

How do I respond to this moron?

How you can even believe logic is accurate especially if we arose by chance. What if evolution flawed our reason how can you prove reason isn't flawed? By using reason? Thus you have to have faith that reasoning actually works.

I've never had to respond to anything this brain-deadening.

I suggest using the pancake bunny. That statement made absolutely no sense at all. I've read it three times, and it still makes no sense.

If you don't have the pancake bunny hosted somewhere, I have it here.

Basically questioning the validity of logic. It still makes me see spots.

Ask him how he can logically argue against logic, given that by his argument, all logic is flawed. His "logical" attack on logic is self defeating, by his own admission.

It's a form of solipsistic bullshit. We use logic because it works: logic is how we know a conclusion follows from a hypothesis. Point out to him there is no evidence faith works, while there are mounds of evidence logic does. Then, when he keeps throwing up a WoI, accept his concession; in the long run, debating this guy is probably a waste of time.

[Saurencaerthai]

Thanks all, this has proved to be helpful!

[Vendetta]

I assume just calling him a silly cunt and telling him to shut up is out of the question?

[Akhlut]

Surlethe, what's a "WoI"?

As for the OP, I think everyone else hit the nail on the head. You might bring up something about various "P = Q" proofs and/or the relation of math to logic and how if math were wrong, we'd probably be unable to do much of anything in our modern world, as most of it requires math at some level.

Wall of Ignorance.

What exactly about logic excludes chance? It is logical to say, "There's a 60% probability that X is true."

What if evolution flawed our reason how can you prove reason isn't flawed?[/]
Evolution and reason have nothing to do with each other. Reason is a concept independent of biological organisms. Our propensity to use reason has clearly been flawed. Why else do we have wars based on imaginary sky pixies who fly around and fuck "virgins"?

Thus you have to have faith that reasoning actually works.

Yeah, the same kind of faith you need to know that 2+2=4 works.
We have examples of logic working all around us. Whenever logic fails, it is because of a lack of information. The principles of ethics, mathematics and science, which clearly work, are based on reason, and in math, pure proof.

It's a stolen concept fallacy, since he's questioning reason using reason, not appearing to realise that reason cannot precede reason in reasoning.

Evolution is not simply chance; it favors organisms that can deal effectively with their environment. Even if evolution is responsible for our ability to reason (a completely unproblematic claim as far as I can see), it doesn't have to be without all possible blemishes--the more pertinent issue is whether or not it is effective, or at least more effective than alternatives, in dealing with reality.

It's a stolen concept fallacy, since he's questioning reason using reason, not appearing to realise that reason cannot precede reason in reasoning.

The fallacy is due to an insistence on absolutes rather than stealing concepts or anything else. Simply questioning reason using reason is not a fallacy. If some persons claim to have found a logical inconsistency in the application of reason, it does not obligate them to actually hold that logic is a valid method, because it is a challenge to the opponent's position rather than their own. A proponent of such a position could simply say "you're the one who believes in reason, whearas I do not, therefore it is a problem for you but not for me." Since the logical validity of arguments independent of the doxastic states (or any other properties) of their proponents, the insistence that this person's belief constitutes a problem is itself a clear ad hominem. All one can say about persons who reject reason is that their beliefs are unreasonable, a tautology. To some extent, this is worse than solipsism--even if this person actually uses logic and reason in other areas, this fact does not have to convince him or her to accept it as a valid method, as consistency is a virtue of reason, which is rejected.

[Zero]

Just tell him that his assertion is also based on logic, so he must share your faith in it, or reject his own comment.

[wolveraptor]

Wait, that he's using logic to attack logic is illogical, which is completely in tune with his position, which is that logic is not valid.

[Morilore]

Actually, his argument is not self-defeating, since there is nothing in that argument that applyes logic and/or reason anyway.
