We get attached to pastorals because they offer a present condition of certainty and stability and a utopian future promise of absolutely perfected certainty and stability. Arrival at the utopia seems like a well-deserved reward for hard-won Promethean victories. Pastoral utopias are where the victors of particular historical finite games hope to secure their gains and rest indefinitely on their laurels. The dark side, of course, is that pastorals also represent fantasies of absolute and eternal power over the fate of society: absolute utopias for believers that necessarily represent dystopias for disbelievers. Totalitarian ideologies of the twentieth century, such as communism and fascism, are the product of pastoral mindsets in their most toxic forms. The Jeffersonian pastoral was a nightmare for black Americans.
When pastoral fantasies start to collapse under the weight of their own internal contradictions, long-repressed energies are unleashed. The result is a societal condition marked by widespread lifestyle experimentation based on previously repressed values. To those faced with a collapse of the World Fairs pastoral project today, this seems like an irreversible slide towards corruption and moral decay.
