No. The goal of the philosopher is to pursue wisdom. And when truth gets too far off track, the goal becomes to resist the insanity and reestablish enough truth for wisdom to be pursued again. This all started with Urwrong and Arc arguing over what a circle is, thus I mentioned “definition” to clarify and resolve the issue.
The entire issue is about language and identifying things in accord with whatever language there is.
Mag’s mistake is in presuming that whatever language he inattentively picked up is the language that dictates the identity of what he sees. He now preaches that physical reality determines language. That is in exact reverse. Language is formed by giving portions of reality identities - defined names. It is then from definitions, usually merely connoted from family and society, that anyone has the urge to call anything by any particular name.
A circle is not what the physical universe says that it is. It is often not what the child associated with the word. The universe doesn’t make that determination. People choose what is to be called a circle, whether it is an abstract category of shape or a physically real object.
But that is only half of his failing.
In addition to not understanding that definitions inherently precede perceptive identifications, he has latched onto the idea that abstract notions (categories) “have no meaning”, even while he is using such meanings and categories. Using his theory (void of categories), the first crude “circle” that one sees determines what a circle is. Anything you see afterward not exactly matching that first identification, would not be a circle because it doesn’t exactly match the identifier. There could only be one circle, the first he ever identified. Of course, he hasn’t thought that far, so he merely re-designates whatever he feels like, as a “circle” “because it is what he sees” regardless of what it might really be.
He is merely a corruptor of language with a primitive, grunt-like mind (no doubt a meat-eater). None of this has anything to do with actual philosophy because without a consistent language, with children choosing arbitrary definitions of their words, there can be no communication. And communication is required during philosophical pursuit in order to build secure, enduring thought and the pursuit of wisdom.
