Revival of Optimism

I am taking online seminary and I am once again faced with eschatology as a discipline ona theologian. Pessimistic eschatologies have been popular for a century, but there is am alternative theology, a theology of dominion. It was the reigning faith of the Puritans in that first century (1630-1660) when they began to sundue the wilderness of New England. It was the colloborated faith of the American Revolution. It began to fade in the rise of Darwinian evolutionary heresy in the second half of the nineteenth century. Why has it faded?
