I've been lurking around this maillist for a long time but I haven't really contributed with anything. I really like the discussions, arguments, recommendations of the group. Very thought provoking. I'm looking forward to participating a lot more in the conversations :)
If not the same, the manga Ouroboros is very similar to what Cecilia described.Another manga recommendation is the the historical work of Sentarō Kubota - Bokko ( translated as "Mohist attack" ) which narrates the story of a monk from the clan that preaches Mohism.
