I use the Yin-Yang Taoist symbol because it represents the duality and dynamic tension between opposites. I have chosen to use it because I am trying to capture and understand a truth (that we thrive as social animals who cooperate) but not preaching the truth (because we also obviously do compete). What I do insist on is the equal validity of this cooperative truth as an alternative to the uncritical acceptance of competition, individualism and winner take all.
