"he passed himself off as being an expert in philosophy, Latin, and Greek."I disagree with this charecterization, I think he holds himself out to be a student of those subjects, as Socrates would."Thirdly, he never contributed anything, to my knowledge, in the General Topics or Technical Section."My contributions also are thin on the ground there. As are a lot of folks.The reason is I am a student of lie algebra, not an expert (like you). I am an expert in some things in finance (boring to most everyone here, but they pay me to be a Prof. so what am I gonna do? throw the money away 'cause I don't know as much about mersene twisters on obscure theoretical surfaces? Plus, I mysteriously, dumb as I am, I generate Sharpe and Information ratio beating alpha every year...I'd rather be lucky than smart!).Some folks don't post in those sections because others say it so much better. I can understand a lecture on Vega and Rega by Marco Avellenada with the best of them, even ask him a good question. Explaining what I understand to someone else is beyond my skill set. While explaining what I know well (and again, dull to y'all) is easy. Aaron has a particular gift for lucidity, as does Paul, Johnny, and a host of others, my friend Collector, Omar, etc.Excluding or pounding someone because they don't know as much as you has downside risk for you....there is always someone smarter than you who could treat you the same way. Jim Simon is famous for being kind and encouraging to those of less mathmatical skill than himself, since that is nearly everyone on the planet. One would do well to adopt his model.Off to teach my students about Discounted Cash Flow. Their first finance class. In one month they will be a Black-Scholes. After that, watch your back, I release these alpha snipers onto your markets friends.
