This is part of the discussion on the [[ethics of law and morality.]]. There are two themes on infant behavior: 1. That they have natural altruism. 2. That this natural altruism has limits. Point 1 has a perceivable barrier even before touching point 2: infant altruism is limited to known people. Infant altruism does not extend to strangers. In fact, now I move on to point 2's limitations: the altruism perceived by infants to known persons is turned to hostility and disgust towards strangers. Furthermore, there is evidence of envy and a lack of fairness. These two points are referred to as the In- (local )and Out- (non-local) groups, respectively. Consequentially, education is seen as the expansion of the circle of concerns and the ability to teach children on impartiality. This is the reason why art and backpacking is important. I know backpacking seems more random than art, however, statistically, backpackers (hitchhikers) are known to be much more gentle and caring in nature. They are more open-minded and willing to help others. Sometimes, education fails to teach children these vital principles. As a result in our modern times, as Mill put it, "men do not desire to be rich, but richer than other men." This saying is applicable to a lot of situations.
