Davelj, yes I agree that no action is 100% altruistic. However, like most things in life, selfishness and selflessness is not black and white. You giving your time and or money to a charity is more altruistic than if you spend that money/time on yourself. In Brian’s example, the parents could have easily gotten divorced. However, according to Brian, they didn’t because of the kids. Giving up one’s happiness for another happiness is pretty altruistic to me. Not 100% altruistic, but much more altruistic than kicking your kids to the curb and get a divorce.
