In the “Afterword,” Matthew Frye Jacobson notes that we live in a moment of flourishing documentary experiment that, like earlier moments, feels especially urgent. If the historical, social and political challenges we face seem frightening and strange, Jacobson contends, it is in part because we cannot fully comprehend them and are out of our depth as we try not only to reckon with uncertainty but also to write, teach, and agitate. All the more powerful, then, as Jacobson argues, is an understanding of documentary as “a way of knowing … an engagement with knowing.”
