A quantitative interpretation is given of the (in)coherence that moral agents experience as a tension between their ordered moral judgments over n physically incompatible actions, and the competitive ordering of motivating intensities (or, desires). Then a model describing one’s tendency to reduce the experienced in-coherence is constructed. In this model, moral sensitivity (S) and desire attachment (e) function as primitives that motivate from opposing perspectives the reduction of incoherence. Two distinct sub-processes of this reduction are therefore initiated by (S) and (...) (e) co-ordinated (more or less efficiently) by the agent’s degree of rationality (R) characteristic of her capacity to handle such internal tensions. This process ends when a new equilibrium between what motivates and what resists (further) reduction has been reached. A macro-equilibrium is described involving (R) constrained by weakness-of-will (W w ). A reinterpretation of the Aristotelian characters (enkratês, akratês, etc.) and an exegesis of Hume’s ‘Calm Passions’ follow as applications. (shrink)
