Untruth as the New Democratic Ethos: Reading Michel Foucault’s Interpretation of Diogenes of Sinope’s True Life in the Time of Post-Truth Politics

Since 2016, the rise of post-truth politics has created a situation of democratic discontent in the west. While many scholars tend to regard post-truth politics as a threat to democratic order, I would like to propose that what we have been witnessing in this form of politics has been the transformation of the democratic ethos. By turning to Michel Foucault’s lecture on the true life of Diogenes of Sinope, delivered at College De France in 1984, I ascertain the framework for demonstrating how we can approach a new shape of democratic ethos in our era of post-truth politics. I argue that in Diogenes’s true life, Foucault saw the concrete life, which could liberate each individual from the constraints of their conventional lives by emphasizing the material conditions of all human bodies. Diogenes’s life could then be a form of self-emancipation since it not only showed how untrue the conventional life was but also released each individual from any conventions estranged from them. Relying on this point, I propose the notion of untruth as the new ground of our democratic lives. Though post-truth politics destroys the objective form of truth, the untruth—as its main element—can play a leading role in grounding our democratic ethos to the extent that it asserts our capability of self-emancipation.
