Wow, seriously, that's the way we ought to treat people who "demolish" our ideas :-)
Edit: I should probably say that I have been trying to behave like this for a few years already at my scale, my point is that this is inspiring.
Oh, and there exist people who are so toxic on top of being blunt that I probably wouldn't work with them even if it gave me a 5% chance to make the worlds first commercial viable fusion reactor.
By the way, it's alleged by a famous professor(?) and amazon reviewer Michael Emmet Brady that Ramsey in no way "demolished" his theory and that this particular problem has drawn people away from respecting and appreciating Keynes immense work in philosophy of probability
If you would like to know more about Frank Ramsey from the perspective of his wife, brother, friends, coworkers and even himself, I found the BBC program "Better than the Stars", from 1978, blissfully exciting.
You will hear what he thinks about Bertrand Russells remark on the small size of men in relation to the universe, truth and probability, mountain walking and even how many hours he worked every day +++! :-)
> He had a profound influence on Ludwig Wittgenstein, persuading him to drop the quest for certainty, purity, and sparse metaphysical landscapes in the Tractatus and turn to ordinary language and human practices.
Interesting. In the preface to the Philosophical Investigations, Wittgenstein credits the Neo-Ricardian economist Pierro Sraffa with something like the same influence. I'd be curious to know what led Misak to this conclusion.
Ramsey was the one who dug Wittgenstein up out of his self-imposed village solitude and convinced him that the Tractatus was fatally flawed (he attacked W’s treatment of the color exclusion problem), and remained a significant influence on W. More so the Sraffa in real terms.
There is a section that uses the same type of thinking that you can use to prove the R(3, 3) = 6 case (often known as the Theorem of Friends and Strangers ), towards the end of the paper  (though in a pretty different way). Proving the general case of things is often very removed from the proofs of a specific case, so its interesting to see similar thinking in the general case.
Also, I really like the simplicity of the proof of the Theorem of Friends and Strangers. You can show someone the proof with two colored pens in 10 minutes. But at the same time, it uses some interesting proof tools: contradiction, the pidgeonhole principle, creating a boundary by counterexample (ie that R(3, 3) must be greater than 5). So I like the Friends and Strangers proof for its elegance and how fun it is to show people, and I like Ramsey's proof because it captures some of the fun of the R(3, 3) case while proving something much, much more difficult.
I'm not sure I'd interpret that result as "chaos is impossible". I'd rather say that you can always find some apparent pattern (of smallish size) by searching through enough randomness/chaos. That seems intuitively to be fairly unsurprising considering everyday experiences like cloud gazing, or the existence of conspiracy theorists. Whether the pattern you find has any important meaning is an entirely different question.
I think a reasonable interpretation of the result is the idea that all "chaotic" graphs of sufficient size _must_ contain order, which isn't as strong as "chaos is impossible", but isn't very intuitive to me.
I think my all reasonable estimates, he was a polymath, maybe not on the level of Kolmogorov or something but it's the fact that he died so young, had such immense influence, and worked in so many fields.
Its a brain bug - our brain makes a flat copy of everyone we meet. If we can not comprehend/ deduce what he/she does the brain is hardwired to early out - and the person is either (depending on outcome) a idiot, or a genius.
If you want to be percieved by others as genius, this can be easily accomplished. Engage in endavours where you control the outcome, but make a show of beeing percieved as a mumbling fool, doing seemingly nonsense on the way.
Right or wrong, this is an assertion not a style. Given that according to whoever wrote the Wiki article on Ramsey he was a 'British philosopher, mathematician, and economist who made major contributions to all three fields before his death at the age of 26' most people would have to rely on the judgement of specialists in these fields to appreciate his achievements. So it probably is 'hard' for the rest of us.
