Two growing phenomena, polarization and populism, are significantly shaping how people determine and use truth, sometimes in ways that jeopardize the ability to reason together well. In this Presidential Address to the Ohio Valley Philosophy of Education Society, Sarah M. Stitzlein sheds light on how polarization and populism pose threats to civic reasoning by problematically shaping how citizens employ truth and the evidence it relies upon. She engages the pragmatist tradition, especially Deweyan approaches to classroom inquiry, to ultimately offer educational guidance on how schools might address polarization and populism in ways that preserve or improve how to use truth in civic reasoning.
