On Losing Certainty

This paper develops a phenomenological account of what it is to lose a primitive and pervasive sense of certainty. I begin by considering Wolfgang Blankenburg’s descriptions of losing common sense or natural self-evidence. Although Blankenburg focuses primarily on schizophrenia, I note that a wider range of phenomenological disturbances can be understood in similar terms—one loses something that previously operated as a pre-reflective, unquestioned basis for experience, thought, and practice. I refer to this as the loss of certainty. Drawing upon and integrating themes in the work of Wittgenstein and Husserl, I propose that losses of certainty centrally involve the inability to tolerate a certain kind of uncertainty. The contrast between having and lacking certainty is to be construed in terms of differing patterns or styles of nonlocalized, practical, bodily anticipation. I conclude by showing how this conception enables us to better understand various different disturbances to which human experience is susceptible.
