Calling KN Out On His Sophistry

Sophistry: “n. a subtle, tricky, superficially plausible, but generally fallacious method of reasoning.”

In a comment earlier today Kantian Naturalist stated: “The idea that the capacity to engage in reasoned discourse depends upon a commitment to ‘the rules of right reason’ is silly (at best). For one thing, there are no such rules.”

KN, I am calling you out on your sophistry.  I challenge you to answer the following three simple true/false questions.

For any proposition A:

1: A=A. True or False.

2: “A is B” and “A is not B” are mutually exclusive. True or False.

3: “A is B” and “A is not B” are jointly exhaustive. True or False.

KN knows as well as anyone that the three classic laws of thought, i.e., the rules of right reason, are logical axioms that cannot be denied on pain of self-referential incoherence. In other words, in order to deny one of the three laws, one must first affirm it.  What will he do now?

Prediction: KN will either ignore this challenge or dig deeper into the hole of sophistry he has dug for himself.

@KN Reminiscent of the answer to the universe's fine-tuning, we now see invoked logic's multiverse option. :PJGuy

I'll be out of town for a while, so I won't be commenting much. In the meantime, here's some reading for you: Paraconsistent logic (Wikipedia) Dialetheism (Wikipedia) Dialetheism (SEP)Kantian Naturalist

About the second law: “A is B” and “A is not B” are mutually exclusive. How about mixed emotions? Let's say that a person (A) is 50% in fleeing mode (B) and 50% in attack (not B) mode. Or sad and happy, or afraid and unafraid. What do we say? “A is B” and “A is not B”? In these scenarios it is probably more accurate to say that A is partly B and partly not B. So the second law states that it is impossible for A to be completely B and to be completely not B at the same time. Right?Box

I don't think KN will ignore this, that's just not his style. And for that I respect him. That ought to be worth about 20 rupee.Mung

A is A. The Law of Identity. Just try to reason without it. A is not ~A (not A). The Law of Non-Contradiction. Just try to reason without it. These aren't rules, per se. Rules can be broken. That's why they are called laws. To deny them is to engage in self-contradiction. To deny them is to embrace absurdity and irrationality, the enemies of reason.Mung
