Human beings are in essence self-centered and conceited, and they often consider tolerance to be a mere human "invention." However, the behavior of animals that live in herds, packs, or any other form of organized togetherness, have rules of behavior too, which cannot be broken, because breaking the rules is punished. The wolves, for instance, kill their own offspring if it threatens by its behavior the whole litter, or if it does not adhere to the pack. Evidently, tolerance toward other being ensures survival of both the individual and the group. Likewise, humans have a natural affinity for tolerant or intolerant behavior. This does not mean that both forms of behavior could be easily learned and internalized. Therefore, those who bring up children, primarily their parents, are responsible for the level of tolerance or intolerance that their children are showing. The education for non-violence and tolerance needs to start from the first day of life of each living creature. Unless the family emphasizes and encourages stereotyping and prejudice toward all that is different from their beliefs, attitudes and values, the tolerance of difference within the family, which children primarily learn by observing the behavior of their own parents, will gradually involve other people, things and ideas in the outside world. Tolerance is more than an educational goal; it is a means of building a non-violent society that does not approve and does not allow violence and force. Tolerance towards other human beings involves a conviction that what we think, believe and appreciate is not necessarily better from what other people think, believe and value. It could serve as the basis for the development of a society whose members will consider difference in a responsible fashion, and work for acceptance of those who are different, and also for the better quality of life of all of us.
