How to Make Impossible Decisions

Abstract

In this paper, I propose that Derrida’s writing on the impossibility of justice has the potential for fruitful dialogue with Ruth Chang’s contemporary account of practical rationality. For Derrida, making a just decision must always come with a moment of undecidability, a “leap” into the unknown with an experience of doubt and anxiety that continues to “haunt” the decision-maker. By contrast, in her work on rationality, Chang proposes that hard decisions are difficult to make because the alternatives are “on a par,” such that there are no rational differences between the alternatives that would contribute to choosing one over the other. Hard decisions are made by expressing one’s own rational agency, generating will-based reasons to commit to or “drift” into one of the alternatives. Derrida writes of anxiety, doubt, and impossibility, yet Chang writes of commitment, agency, and rationality. Despite these differences, there are important comparisons and connections between the two accounts that are worth exploring. I suggest that the moment of the decision which Derrida describes as heterogeneous to knowledge can be understood as a moment of parity in which there is a lack of given reasons, as explained by Chang. Chang’s account of rational agency provides an interpretation of how decision-making is possible despite the undecidability as described by Derrida. This notion of commitment and agency as explained by Chang is not incompatible with Derrida’s insistence that the responsible decision is haunted by anxiety and doubt. Instead, I suggest that Derrida’s writing highlights uncertainty as central to understanding the nature of hard choices and how to navigate the demands of justice.
