"#Humans have evolved #gregariously. We delight in each other’s company; we #care for one another. #Altruism is built into us. We have brilliantly deciphered some of the patterns of Nature. We have sufficient motivation to work together and the ability to figure out how to do it. If we are willing to contemplate nuclear war and the wholesale destruction of our emerging global society, should we not also be willing to contemplate a wholesale restructuring of our societies?"

- Carl #Sagan, Cosmos, Futura, 1987, p. 358
