" Each cell of a living organism cooperates with the cell next to it. It does not need any sentiment or declarations of undying love to do so. Each cell is wise enough to know that if its neighbour goes, it also goes. The cells stick together not out of brotherhood, love and that kind of thing, but out of the urgent drive to survive.   It is the same with us, but only in a larger scale. Soon we will all come to know one simple thing: if I try to destroy you, I will also be destroyed. "

― U.G. Krishnamurti , Society (It's terror, not love that keeps us together...)
