Abstract

This essay is part of a special issue celebrating 50 years of Political Theory. The ambition of the editors was to mark this half century not with a retrospective but with a confabulation of futures. Contributors were asked: What will political theory look and sound like in the next century and beyond? What claims might political theorists or their descendants be making in ten, twenty-five, fifty, a hundred years’ time? How might they vindicate those claims in their future contexts? How will the consistent concerns of political theorists evolve into the questions critical for people decades or centuries from now? What new problems will engage the political theorists (or their rough equivalents) of the future? What forms might those take? What follows is one of the many confabulations published in response to these queries. Our earth is approaching its end. Through Project Arcadia our species has a chance at escape. In this paper, I want to argue that Arcadia is all things considered unjustifiable and unadvisable. It is unjustifiable because human beings have proven themselves incapable of stewarding sentient life on planet earth; for example, our collective response to climate change has been dire, handled almost exclusively through adaptation, committing vast areas of the world to desolation, desertification, or disappearance. Basic respect for life, and what we likely will make of some other instances of it, should counsel humility as we contemplate relocating ourselves to other life-supporting domains. It is inadvisable because our species, like the world, is impermanent. We will, at some point, have to contemplate the ceasing of our existence, and it is my argument that we contemplate this ceasing on the terra firm of our own planet. In conclusion, and drawing on the work of Samuel Scheffler and the Japanese concept of mono no aware, I will argue that there is considerable value, admittedly tainted with considerable melancholy, to be had in grasping the opportunity provided by planetary devastation to achieve some semblance of narrative completion.
