Hegel (as echoed by Marx): "merely quantitative differences beyond a certain point pass into qualitative changes" ( https://www.pnas.org/doi/10.1073/pnas.240462397 )
I always found that an interesting observation, whatever you think of the rest of their works.
The best people have silly beliefs, the worst people have great insights, and the vast majority of us are in-between.
If we discard everything "tainted" by imperfection, we'll be left with nothing good.
Anyone whose even tried to read stuff of his I.e the phenomenology of spirit will tell you that he’s a charlatan and hack, and the people who constantly cite him (I.e Zizek, Lacan, Foucault) are also hacks.
Myself, I appreciate Schopenhauer a lot more, and we know what he thought of Hegel, but I'm not fanatical about it. If a hack hits on a good line, I'll nab it.
