A lot of people live thinking about their work, study, self, and/or others. Because people are in a human community, we have to interact with each other anyway. Interaction needs respect. Communication needs respect. It goes on and on therefore everything needs respect. I think 'LOVE' is based on respect. If people treat others with love and respect, altruism forms eventually. It is said "I think, therefore I am," by Decartes. Well, Think of others first then oneself creates not only self but also others too.
