I love to think about philosophy but don't like reading it. One of the few "greats" that I've spent any time on at all was Thoreau, who espoused a similar view of the evils of civilization. He was very poetic, which is nice, but he was still wrong. :-P
Stephen Pinker did a pretty thorough debunking of this is "A Blank Slate: The Modern Denial of Human nature". For one thing, the murder rate of "savages" is astronomically higher than that of modern society.
This is one of the things that bugs me the most about philosophy. Philosophers are only possible with civilization--you don't have time to sit around Thinking Big Thoughts if you're busy trying to survive from day to day. Which probably none of us, here, have had to experience--having won the Population Powerball by being born in the United States in the second half of the 20th century.
Living outside of civilization is way overrated. It is difficult even to imagine how hard it would be, so I have trouble with people who try to ennoble it or make it sound like some kind of utopia.
I also think of John Adams' lovely quotation:
"I must study politics and war that my sons may have liberty to study mathematics and philosophy (that is, natural philosophy--what we now call physical science). My sons ought to study mathematics and philosophy (again, natural philosophy), geography, natural history, naval architecture, navigation, commerce and agriculture in order to give their children a right to study painting, poetry, music, architecture, statuary, tapestry, and porcelain."
You can't have great learning--or philosophy--without civilization. So any philosopher who declares the sort of "noble savage" foofoo just makes me... how did yarb put it? It makes my piss boil.
"Nature destined him, he said, to be a scientist, but there were no opportunities for scientists in pre-revolutionary Virginia. Other, more urgent, needs took precedence. He threw himself into the historic events that were transpiring around him. Once independence was won, he said, later generations could devote themselves to science and scholarship"
