You only represent yourself. — panwei

You still have no argument.

So you seem to have something like

'You cannot skip eating, or you will die.'
Fundamental Purpose = Service Target (One's Own Group) × Final State
therefore, you ought not skip eating.

Any discipline that deals with human action is incapable of explaining any single social phenomenon without relying on a meta-teleological postulate.
In Chinese history, hypotheses such as "human nature tends toward benefit" — which is itself a meta-teleological postulate — have been proposed repeatedly for millennia.
Contemporary economics similarly operates on the Rational Agent hypothesis, which is, in essence, also a meta-teleological postulate.
Even theories that do not explicitly set forth a meta-teleology inevitably rely on one for explanation — A Theory of Justice is a case in point.
My Axiom of Purpose is likewise a meta-teleological postulate. It shares the same fundamental attribute as all the postulates mentioned above; the only difference lies in its structure.
Therefore, you can only speak for yourself.
There is content I am willing to share on this forum, and content I am not — at least not for the time being. High-value ideas that have not been formally published in academic papers represent the culmination of years of personal work. This really should not require explanation.

This argument is clearly invalid.

Yes.

It's how you seem to have set up your argument.

Have you a valid variant?

I certainly don't argue my point in this way, but I won't explain how I did it here, so you don't need to ask.

Then my conclusion is that I've show that your argument is invalid.

As long as you're happy.

I'm not very happy with your account. But if you will not explain, so be it.

I regret that this has caused you dissatisfaction; that was never my intention. However, I must protect myself in the course of this exchange. The fact that you find it difficult to comprehend how my argument is constructed only underscores its significant value.

I personally have no complaints about you. If you feel that my attitude is bad, it must be a translation problem.

So you could say that within the framework of traditional Chinese views, "human nature tends toward benefit or recognition of one's group" is an axiom. That's how axioms work: there has to be a community that views it as self evident. You can't just say, "This is my axiom" and then expect others to accept that. It doesn't work that way.

The rational agent hypothesis is that each individual rationally works for his or her own benefit. There is no expectation that an individual will consider the welfare of the group he or she belongs to. But keep in mind that the rational agent hypothesis has been called into question in recent years because of its tendency to produce wrong results.

How is this argument, provided by @Banno different from your argument?

So you seem to have something like

'You cannot skip eating, or you will die.'
Fundamental Purpose = Service Target (One's Own Group) × Final State
therefore, you ought not skip eating.
