Whether rationalism when concerned with explanations of moral motivation should stand in opposition to the relevant Humean approach is a perplexing question that is oversimplified when reduced to a rationalism vs. Humeanism clear cut opposition about the possibility of rational control over desires.This paper criticizes the significance of this simplification as well as the hypothesis of unitary psychological states constituted by beliefs and desires (referred to as 'besires') and their alleged capacity to secure rational control over desires. Besires contribute in (...) the explanation of moral motivation only indirectly, that is, not as permanent unitary psychological states but only as relatively very short-term 'backgrounds' to subsequently detached matured desires.This interpretation further explored shows that the rational demandfor a genuine rational control over desires presupposes rather than opposing to the Humean belief desire distinctness - the latter actually securing the possibility of genuine moral incoherence as long as we intend to understand it neither as irrationality, nor as psychological deficiency.

Moral internalism and moral externalism compete over the best explanation of the link between judgment and relevant motivation but, it is argued, they differ at best only verbally. The internalist rational-conceptual nature of the link’ as accounted by M. Smith in The Moral Problem is contrasted to the externalist, also rational, link that requires in addition support from the agent’s psychological-dispositional profile; the internalist link, however, is found to depend crucially on a, similarly to the externalist, psychologically ‘loaded’ profile. It (...) is also argued that the differentiation of the two competing explanations is insufficient partly because they both fail to consider crucial quantitative parameters of the judgment-motivation link. Such parameters become very important particularly in the light of Smith’s claim that this link is grounded on the observable “striking fact” where changes in the set of one’s moral beliefs systematically bring about changes in one’s moral behavior. Examples of algorithms measuring moral coherence and moral worth are provided to serve as evidence for what it comes down to, vis-à-vis the alleged fact, only a verbal dispute between the two camps. Finally, the ‘misfiring’ of these explanations is understood in connection to the irreducibility of concepts such as ‘moral worth’, and/or, ‘moral sensitivity’. (shrink)

The logical form of an inductive step figures as a deductive fallacy: concluding the antecedent from affirming a conditional and its consequent. In the sphere of practical rationality, however, where concerned with the presuppositions of action and the interactions between beliefs and desires, certain schemata have been proposed that express rational demands on agents who desire things to happen in the world. In this context, if agent A desires to φ and believes that ψ brings about φ, then, A is (...) rationally expected to desire to ψ. But it is equally rational to expect that A’s desire to φ presupposes her belief that a certain state of affairs obtains where φ is a possibility. It then follows that assuming a desire to φ and a belief that ψ brings about φ, we can derive an logical form that approximates that of the above inductive step: the beliefs that φ is possible and that ψ brings about φ entail the belief that ψ is possible. It remains an open question whether this conclusion adequately supports the rationality of the exact inductive schema. (shrink)

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)
