 Value incommensurability also features in debates about akrasia (Nussbaum 2001, 113–117). David Wiggins, for example, invokes the idea of value incommensurability to suggest “the heterogeneity of the psychic sources of desire satisfaction and of evaluation” (1998, 266). This heterogeneity, according to Wiggins, allows for a coherent account of the agent’s attraction to what is not best. It allows for a divergence between desire and value such that the akratic individual can be attracted to a value that should not be sought at that point in time. Wiggins invokes value incommensurability to capture the idea that a gain in the value that should not be sought does not reduce the loss in choosing what is not best.
