"If we look back at our history, we can think of competition as it relates to the animal kingdom. It is natural for animals to compete for food in the struggle for survival... But we are not just animals. Although we owe our bodies and certain of our instincts to the animal kingdom, we are souls in incarnation. As souls, something other than competition comes into play in the relationships between men and men, between groups, between nations... With the advent of agrarian civilizations, the necessity for competition diminished. Competition in terms of warfare still took place very often, but the very fact of turning to settled agrarian culture led man away from the necessity of chasing each other, or animals, for the pot. A different aspect evolved: co-operation. Tribes grew in size, little market towns grew up, trading took place... You cannot build a town or a trading station without co-operation. You cannot enlarge the range of human activities and become creative without cooperation. If some are digging the soil, it allows others to build the houses. If some are building the houses, it allows others to play the flute or the harp. These differentiations and specializations enrich human society, civilization and culture. Without the spirit of co-operation none of that richness can be fostered. It needs the sense of oneself as part of a group, a community, brothers and sisters sharing the resources of a particular place, and enjoying, therefore, the fruits of this cooperative interaction."
