  This view recuperates many of the ideals of the Enlightenment—such as freedom, autonomy, and justice—but in a way that drops the Enlightenment’s metaphysical assumptions about reason, progress, and human nature. Instead of seeing these ideals as grounded in some metaphysical facts, this new view sees them as ideals that people hold and try to instantiate through practice and imagination. Where many ancient and modern ideals of politics were based on suppositions about the nature of reality or of human beings, contemporary political philosophies generally operate without supposing that there are any universal or eternal truths. Some might see this situation as ripe for nihilism, arbitrariness, or the exercise of brute power. The performative alternative is to imagine and try to create a better world by anticipating, claiming, and appealing to others that it should be so. Even if there is no metaphysical truth that human beings have dignity and infinite worth, people can act as if it were true in order to create a world in which it is seen to be so.
