When the HN guidelines say the following, it applies to articles as well: Please respond to the strongest plausible interpretation of what someone says, not a weaker one that's easier to criticize.
With this definition in mind, it's logical that the concept of "precursor" or "unknow philosopher/thinker" seems just absurd to some people.
I don't necessarily agree with this definition but we can't really blame nickysielicki for this very frequent point of view.
I agree with you on this-- it's definitely interesting, but the point you're making here is very different from the thesis of the link. The thesis restatement in the last paragraph of the article makes the case that these authors have high historical relevance in philosophy, and that argument is what I was responding to.
I understand the goal of the guideline, but as a starting point it's unreasonable to expect someone to respond to an argument as it could be rather than as it really is. I think we're on the same page.
And further, intellectual popularity among a philosophers contemporaries and immediate successors. That makes it rather difficult to introduce a new thinker.
Before all the aforementioned authors, it's all but certain that many of these thoughts were had by unknown people without the ability to archive them in depth. The Bible alone is evidence of this; for someone to write that denial of religion deserves death, they must consider religion as a choice in the first place.
This just feels like someone is shoehorning a narrative that they like.
