Anarcho-Mercantilist:

Evolutionary biologists, in explaining sexual selection, assume all humans as heterosexual. This assumption will simplify their theories by leaving out the analysis of homosexuality, which they consider as irrelevant to sexual selection. For example, they define the terms "male" and "female" as necessarily heterosexual and free from physical and mental defects.

Assuming all males and females as necessarily heterosexual does not imply that we should condemn homosexuality. Doing so will lead to the appeal to nature fallacy and a disregard to abstractions. So please do not take personal offense. Even if we found out that homosexuality does not increase the propagation of its "selfish genes" by solving overpopulation, that does not suggest any normative judgment for or against homosexuality. Prescribing any value-judgment from only descriptive notions such as nature requires the conflation of the fact-value dichotomy.

Conflating the fact-value dichotomy might lead us to conclude that "homosexuality is wrong." Keeping facts and values separate precludes this possibility.

Well that was a whole lot of nothing. I asked you to present these theorists to strengthen your argument and you merely expanded your old argument with more pladitudes.

Anarcho-Mercantilist:

We know the absurdness of believing that nature will contradict itself if humans do not exist. Earth has existed before humanity.

Humans create the Aristotelian laws of logic just like how humans create art, language, and customs. The universe does not intrinsically value Aristotelian logic just like it does not intrinsically value art, language, and customs. We disagree with each other probably from semantics.

Therefore you are conceding that the Aristotelian laws exist outside of the human consciousness, in nature in fact because you declared it is absurd to believe that nature will contradict itself if humanity is not around. Therefore the Aristotelian laws are not subject to simple subjectivism of the human consciousness but are in fact an objective set of laws that can be understood by the whole of humanity.

Therefore the Aristotelian laws are not subject to simple subjectivism of the human consciousness but are in fact an objective set of laws that can be understood by the whole of humanity.

You have defined "subjectivism" as values and opinions that humans hold. You have define "objectivism" in this context as the reverse of "subjectivism." Therefore, we can label all scientific facts as "objective" in this sense. If you mean this, then I agree with you.

However, I disagree with the notion the Aristotelian laws are true because they are undeniable, and to deny them causes a performative contradiction. Rather, the Aristotelian laws are true because humans assign them as true. They are not "proven true" nor "deducted by an argument by performative contradiction." They are true because humans normative value the three Aristotelian laws.

We have to remind us that the three Aristotelian laws (identity, excluded middle, and non-contradiction) are normative, not descriptive. Unlike scientific facts, these Aristotelian laws are not facts of the universe. Rather, humans assume them as true, similar to the notion when human assume mathematical axioms are true. Like mathematical axioms, these three laws cannot by proven to be true. They are assumed as true for granted. No arguments can prove the Aristotelian laws to be "true." Humans value them, and assume them as true like how humans assume mathematical axioms as true.

The performative contradiction argument is an invalid proof. It derives values from facts. However, as pointed out above, the Aristotelian laws are normative, not descriptive. If the performative contradiction argument thus derives the normative Aristotelian laws from descriptive facts. This confuses the fact-value dichotomy, then values, in this case, are grounded by reason alone. Therefore, the performative contradiction argument is similar to ethical apriorism. Rather than deriving normative ethical commands as in ethical apriorism, this derives the normative laws from logic.

Most of the sarcasm by nirgrahamUK and wilderness is based on the invalid performative contradiction argument in "proving" the three normative Aristotelian laws of logic. We have just refuted the validity of your sarcasm.

Except they are descriptive, not normative. You can't violate the law of non-contradiction and still say anything meaningful.

Here's a performative contradiction for you :

A says to B "Language can't convey meaning".

If they are undeniable then that presupposes they are true. Contradiction does not exist in nature...this is a law that you claim is undeniable...truth+undeniability= Objective truth

Here we go again in a circular argument. The three laws of Aristotle exist outside of the human consciousness. The human consciousness can realize them however they cannot be changed by subjective whims. You have yet to show where contradiction exists in nature. Are we to assume that apples will suddenly become oranges once humanity dies? Will A stop equaling A merely because humans are gone? I think you are purposely beating around the bush on this issue.

Here's a performative contradiction for you :

A says to B "Language can't convey meaning".

The statement "Language can't convey meaning" is tautologically contradictory. By definition, language has meaning. Therefore, you are establishing a contradiction by making incompatible definitions. This refutes it. Therefore, it does not require a performative contradiction argument to refute it.

Also, it does not require a performative contradiction argument to refute "normative ethical subjectivism." It contradicts the definition of ethics itself if we allow anyone to prescribe any moral code. Moral codes, by definition, applies to groups of individuals, and not differ from the group members themselves.

These two examples does not require performative contradiction arguments to refute them. Rather, they are self-contradictory by its incompatible definitions.

Why has that have anything to do with the law of contradiction? The law of contradiction does not explain the properties of the universe as in the sense of how the law of gravity explains a property of the universe. Rather, the law of contradiction helps humans use science and logic, which in turn, how science and logic explains the universe.

The universe does not obey the law of contradiction as in the sense of how the universe obeys the law of gravity. Humans normatively value the law of contradiction for its application to logic. Humans do not normatively value the law of gravity.

Humans use the law of contradiction instrumentally, to reach a goal. Humans use this law to perform logic. However, humans do not use the law of gravity instrumentally. Humans use the law of gravity descriptively to explain the universe.

My writing might seem ambiguous to you. Let me know everything in this writing that seems unclear to you.

Well, part of the disagreement revolves around what a performative contradiction is...

Language does not have meaning 'by definition'. It's in the nature of language to convey meaning. It is language's purpose to convey meaning.

So, if you try to use language to communicate the alleged fact that language can't communicate anything, your very action is contradictory in a sense. I'd call that a performative contradiction, but feel free to call it something else. The fact remains, though, that the assertion "language conveys meaning" can't be denied.
Also, it does not require a performative contradiction argument to refute "normative ethical subjectivism." It contradicts the definition of ethics itself if we allow anyone to prescribe any moral code. Moral codes, by definition, applies to groups of individuals, and not differ from the group members themselves.
So, do we agree that "normative ethical subjectivism" is contradictory and so is a meaningless concept ?
These two examples does not require performative contradiction arguments to refute them.
Well, would you present an example of a performative contradiction ? It seems part of the disagreement is simply related to naming conventions...

how have you come to be blessed with this divine knowledge of the universe, granted your supreme skepticism on all matters of truth and logic?

how about just as gravity exerts its effects without humans understanding or describing it. the law of non-contradiction is fully in effect similarly.

Yes it does. "Things and actions are what they are". The law of gravity presupposes identity.

While we are nitpicking, notice that the figure of speech "the universe obeys this or that law" may be misleading...The universe simply is the way it is.

nirgrahamUK:

Humans use the word "gravity" to describe an observable phenomenon within the universe. The universe does not obey the law of gravity in the sense of how humans obey legal codes. Humans name "gravity" to describe a behavior within the universe observed by them. In this sense, human can arbitrarily name laws to describe any observable phenomenon. Humans can name an infinite amount of laws to describe the behavior of the universe.

However, humans create laws such as the law of gravity to describe only the interesting behaviors and properties of the universe. They leave out the uninteresting behaviors and properties of the universe. Humans create the "law of gravity" because humans find this description interesting and useful.

The law of non-contradiction is not an observable phenomenon like how the law of gravity is. The law of non-contradiction is just an idea created in the human mind.

Oh god, now we are going down the Nietzche memory hole of ever changing titles. Who cares what we call the law of non-contradiction as long as the definition is truthful. You acknowledge the point that the laws exist outside of the human mind yet you are caught up simply on what it is called. Truly a petty point.

Ultimately all ideas are created in the human mind (for the time being at least). That piece of information is not really news...nor exceedingly useful.

Unicorns are also an idea created in the human mind. But it's a different kind of idea.

This means that we agree with each other, but have different views of how the law of non-contradiction "describe" the universe.

Would you name some specific examples of how the law of non-contradiction "describe" the universe?

Contradictory things do happen. For example, humans believe in contradictory economic doctrines. Humans are part of the universe. Therefore, the universe suffers from contradictory economic doctrines. Furthermore, the law of non-contradiction does not describe the universe.

The law of non-contradiction matches fundamental physical facts.

If you burn a chunk of coal, the coal changes from the unburnt state to the burnt state and energy is released.

The coal can't be both burnt and unburnt at the same time. The states are mutually exclusive.

By definition, "burnt" means not unburnt. It contradicts itself by its definitions. Perhaps you can clarify it by using "the law of not contradicting definitions" instead of "the law of non-contradiction"?

Guys, he is just using a Nietzche nihilistic term viewpoint. It is ridiculous to continue this argument. In fact I propose that it is absurd to continue discussion with AM himself. What we just experienced is 20 pages of AM not disproving Aristotelian law  but complaining about what it is called.

Language conveys meaning in the sense that it communicates ideas between individuals.

Language does not convey meaning in the sense that it does not communicate one's feelings, such as qualia.

We agree with this contradiction.

Juan:
Well, would you present an example of a performative contradiction ? It seems part of the disagreement is simply related to naming conventions...

We will list some ethical doctrines that rest on the argument by performative contradiction:

  • Rothbardian natural law
  • neo-Aristotelian ethics (Ayn Rand, Douglas Rasmussen, and Douglas den Uyl)
  • Hoppe's argumentation ethics
  • Kinsella's estoppel theory
  • Universally Preferable Behavior
  • the categorical imperative
  • liar paradox: "I am lying."

I disagree with all those doctrines, not on logical consistency, but on logical soundness. This includes the liar paradox.

The liar paradox has the same problems as Hoppe's "self-ownership" argument. It assumes a presupposition that either a honest truth or lie, similar to Hoppe' performative contradiction of either full-blown Lockean property rights or no property rights. The liar paradox does not assert half-truths, half-lies, partial honesty, just like Hoppe's "self-ownership" argument does not assert partial property rights or slave. They all force one to choose the only option.

The performative contradiction argument is not a sound argument. So even if you will believe that I contradicted myself, I will not.

Logical consistency does not imply logical soundness. Performative contradiction arguments are consistent. However, they are unsound.

It is impossible to deny the performative contradiction argument when we work within the Aristotelian system. In order to refute the Aristotelian system, we must work outside the Aristotelian system to examine its defects.
