What piece of wisdom or knowledge about living as a human is shown in the following quote, pg.11 "But this isn't how it feels to be a bugger,thought Ender. They don't wear this face as a mask, it is their face"?

Ender begins to appreciate Buggers for being more sincere and "real" than humans. The Buggers do not seek to trick or deceive. They are not evil personified: they simply are as they appear. Humans are the ones who wear a "false face".
