> making the world a better place can still be a very selfish act You sound like such selfness is actually concious. I don't think so. We're not Machiavellian machines, gauging the consequences of each of our deeds. For example, I bet most Wikipedia contributors don't especially want to help building the world's most comprehensive encyclopaedia, but just want to share a bit of their knowledge, or just don't like to see spelling errors.
