You're making a silly assumption here in my opinion if I understand your correctly, namely that because X's contribution to field Y was 'bad' all subsequent attempts at engaging with it are bad, therefore X's work must be expunged from the tradition and no longer engaged with.
Hm, so sure, we'll say Hegel was a horrible, illiterate, idiotic sophist. In that case you still have to admit his work was valuable to the field in that it provides a good example as to what constitutes sophistry. So, even if you want to interpret Hegel's work as worthless, intellectual dung-water you could argue that it's valuable in helping shape the philosophical field in a negative sense in that it provides an instance out of which a normative rule can be developed--namely Hegel's work is what philosophy shouldn't be.
I've given you two, admittedly very basic, since we're limited to comments, arguments for why you might consider Hegel's work meaningful/useful:
a. It's historical (accidental) impact.
b. It's being an example of how not to proceed (for a scientific analogue: an experiment that was unsuccessful).
Neither of these positions need to explicitly agree with Hegel's theories to see them as valuable. in either case you can say that Hegel's contribution was 'meaningful' while upholding the idea that he was 'wrong' (in fact the second relies on this).
Okay fine. We'll discredit and distance Hegel because he was 'wrong'. Does that mean we also discredit and distance every lick of philosophical work that in some fashion engaged with his productions?
By today's standards and developing knowledge in the field of linguistics the logical positivists of the 20th century were also 'wrong'. Should they too be eliminated from the philosophical tradition? Are they too unimportant? I'd like you to go and convince an analytical philosopher that work of Frege, Russel, and Whitehead should be eliminated from the philosophical discourse because it was 'wrong'. Or to use your own example, Chomsky was arguably wrong in putting syntax on such a pedestal--but his work was still fundamental in directing the progress of the field of linguistics. Without Chomsky's contribution there's a whole wealth of linguistic inquiry that may have not been undertaken. Concerning yourself with whether or not a historical and terminated event was 'wrong' outside of moral domains is really senseless--I don't see the point. Once again I stress that the humanities are not mathematics. There's not an evident 'right' answer to the things we define. It's idiotic to say that a given political system is 'right' and another is 'wrong' as you're only expressing your own value judgments. It is the same with metaphysics, history, literature, art...etc. etc.
You know, you continue to disparage Hegel but you've yet to produce any analysis as to why he's such a so-called sophist. In your previous post you quoted some of his material but provided no argument; you assumed that it is interpretable as nonsense de facto. That is not the sign of an intellectual, honest, or reasoned approach to the content. Schopenhauer was an incredibly intelligent philosopher but that remark on Hegel is not a valid critique, it is only a contentless value-judgement, dismissal, and ascription--to put that forth as an argument for Hegel's being a sophist is an appeal to intellectual authority, which is an argumentative fallacy.
Here let me engage in a similar exercise with Pascal's wager since to you that sounds >"approachable today because it deals with probability"
Well, Voltaire said this of Pascal's little wager:
[That it was] "indecent and childish" (https://en.wikipedia.org/wiki/Pascal%27s_Wager)(See: Criticism, Nature as Proof of the Existence of God).
Therefore we ought to just discredit and distance Pascal's wager from the philosophical/religious tradition.
Does this sound like solid reasoning/argumentation to you? No? That's because it isn't. And in fact Voltaire's little quotation was based on a misunderstanding of Pascal's wager. Dumb move if I'm trying to effectively and actually discredit Pascal right? Reconsider your position on Hegel and your little employment of Schopenhauer and Gauss.
I'm going to be nasty now because your unwillingness to have an actual conversation instead of spiting your preconceptions at me has annoyed me.
I understand that reading actual critical thought and analysis beyond name and dung tossing is hard work and that we're all lazy, but really, it may do you some good.
For someone who is constantly touting the value of reason you're not very good in exercising it in this case. I can tell you're passionately against Hegel, which appears to be clouding your judgement and has you reaching for ad hominem and value-laden terms like sophistry, stupidity, and childish which are all void of significant analytical content; it's fine to deploy these words, but only after you've done and provided the analytical work necessary to back up your use of them--otherwise it just makes you look childish. You seem to have such a great aversion to Hegelian thought that it "puts your reason to sleep" and prevents you from analyzing the work from a value-neutral position--to the extent it's possible to step back and approach something without looking to reconfirm what you already believe.
Once more you don't seem willing to reconsider your perspective. Notice how you're not asking any questions. Just making statements. I would prompt you for further explanation, but at this point you've made so many reductive claims, value judgements, appeals to intellectual authority, and laudations of maths and science that I highly doubt you have anything interesting to say.
Your language is still stewing with an underlying vitriol, and you'll never be able to coherently reason about Hegel's place in the philosophical tradition, nor convince anyone he really doesn't belong, until you've purged your passion from your arguments.
It's funny, I don't even like what little I've read of Hegel's work; I find it to be a bit flat and over-reliant on baroquism to give the impression of significance, which makes his concepts difficult to untangle. But I'll admit I haven't read Hegel's work in full--that's why you don't see me putting forth value-judgements or arguments about his content. I gave you two approaches to answering why the work is 'meaningful' that don't require a comprehension of the work itself, but only account for its potential pragmatic (example of sophistry) or historical (recognition in the tradition of philosophy) significance.
You began asking why the work was 'meaningful' or 'useful'--but really you just want to argue against Hegelian thought, why, who the hell knows. It seems like you have some personal vendetta. Many of the world religions do not mesh well with the operations of reason. Yet nearly all of them, if not all of them, are incredibly useful. You're a militant rationalist, and like all militant rationalists, deaf to more nuanced calls to reason and suspension of your belief, susceptible to dogmatism when particular words are thrown about, and, also symptomatic, you find value-laden, scathing terminology from recognized intellectuals more effective or significant than any well-formed argument or honest and open engagement with the work.
