Pope Alexander VI (the Borgia pope) deserves consideration. He raised the bar very high for hypocrisy, greed, corruption, ruthlessness, nepotism and a lot of other negative words that I can't think of right now.
I think Alexander VI does not deserve a lot of the criticism he gets, like many of the Renaissance popes.
Churchill was certainly arrogant and pompous, not too sure about the Jerk part. I find it hard to dislike anyone who thought burning De Gaulle at the stake was a good idea.
I find it very easy to dislike someone who wanted to campaign under the slogan "Keep Britain White". Churchill was actually partially responsible for the
rise in racism in mainstream politics in the second half of the 1950s.
I think Newton got some training in being a jerk by how he was treated by the prior recognized head of the scientific establishment. He was obviously a genius but that head could not accept that somebody else might eclipse him and thus pushed many people to doing a hatchet job on Newton's work.
I'm not sure who you're talking about there; there was no "scientific establishment" in Newton's day, just a bunch of nutcases doing weird experiments who happened, as it turned out, to be more or less on the right track. In any case, the hatchet jobs that were done on Newton in his youth were nothing compared to the hatchet job that
he did on Leibniz later on. I suspect that Newton simply couldn't stand the thought of someone else being cleverer than him, and German to boot.
Would you care to expand on that? I'm not trying to be difficult. I just don't know a lot about New Zealand. About the only thing I know is that the sheep outnumber the people. I had always thought that they were a pretty agreeable sort of people. Was it just a joke?
I think he was asking if there's any decent philosophy coming from New Zealand. I have to say I can't think of any. I thought David Chalmers was from New Zealand, but Wikipedia says he's from Australia. Not that I trust Wikipedia, and also there are quite a few New Zealanders who are commonly wrongly thought to be Australian, such as Sam Neill or Russell Crowe.
Anyway, my suggestions:
Paracelsus. So insufferable he spent his life being kicked out of universities and travelled Europe railing against pretty much everyone.
Epiphanius of Salamis. A raving nutcase who thought pretty much everyone was a heretic, and ended up disagracing himself by trying to denounce John Chrysostom as a heretic.
Descartes. Very self-righteous and convinced of his own genius; spent much of his time engaging in angry correspondence with the Dutch university authorities over precisely why his ideas should be taught. Couldn't see why people had a problem reconciling his ideas with religious orthodoxy, because he was convinced that his own ideas had been proven to be correct, so religious orthodoxy just had to deal with them.
Jerome. Undoubtedly the most pompous jerk of them all. Also spent much of his time denouncing everyone as a heretic, including his own former best friend. Unbelievably self-righteous and self-promoting, to the point of denying that he
had ever been an Origenist when his own books proved quite clearly that he had been. Brought shame on the whole church through his bitter denunciations of Rufinus, which continued for years after Rufinus' death. Generally a complete git, but a witty one, so he generally gets away with it.
