For Aristotle, virtue was often a sort of disposition between to unhealthy extremes, sometimes referred to as a "golden mean".
Zeno is best knows for his paradoxes, which often involved the difficulty in conceptualizing infinite regresses. If we applied the type of logic Zeno uses to Aristotle's concept in a rather stupid way, it would cancel itself out.

"Is it always immoral to lie on your dating profile? I mean yeah...but come on guys, I've been on this site for like a year and havn't got any dates...there are limits to every rule."

"How can I cure my anxiety about death?"

Edmond Burke is in some ways the founder of modern conservatism, and is most famous for staunchly opposing the French Revolution. Burke believe that people ultimately understood very little about the forces that governed society, and any changes that we make have to be done slowly to ensure that society doesn't collapse into anarchy. He thought the radicals that wanted to remake society "rationally" during the French Revolution were far too arrogant in their ability to imagine a utopian society from scratch, and any attempt to do so would only result in disaster. While he believed in social progress, he thought we should never make large changes all at once, or we would risk dissolving institutions that we did not fully understand and upsetting the balance in society, bringing large scale suffering.
He wrote Reflections on the Revolution in France in 1790, only eighteen months after the revolution had begun, so a lot of his predictions of unrestrained violence came true. Of course, his ideas such as "actually, democracy is bad", and "women shouldn't be educated" aged a little less well.

"The absolute nerve of some people."

"Not a single person can understand me, could it be something I did wrong?
No, it's every single person on Earth who is wrong."

Supposedly Hegel's last words really were some kind of woeful lament about how no one had ever understood him. Since he's died, and indeed during his life, many philosophers have complained about his obscurism, and even accused him of intentionally writing badly to prevent people from understanding him. While some people, such as Hegel, believed his ideas are just that intrinsicly difficulty to understand, there are others, such as everyone else, who thought he probably could have done a better job explaining them.
