Sophrosyne

So I was reading "Beware the Hubris-Nemesis Complex: A concept for Leadership Analysis" put out by David Ronfeldt of RAND, and found a neat word. "Sophrosyne" It is a pretty neat concept. It is hard to translate into English, so I won't try to. Try, http://www.worldwidewords.org/weirdwords/ww-sop1.htm and http://en.wikipedia.org/wiki/Sophrosyne .
