In this essay I offer a model of change that integrates the main components affecting our choice of futures. The model reflects constraints on the efficacy of human deliberation, but it also holds possibilities for the kinds of change we would choose. I use this model to suggest how we might get from where we have been (a status quo inadequate to address major contemporary environmental challenges) to where we might hope to be (a world that makes room for future generations and a nature not ourselves), notwithstanding flaws in our system of collective decisionmaking that are unlikely to disappear any time soon.
