Abstract

Practical reason is the means by which beliefs and desires come together to produce actions. Practical rationality is difficult because we have many beliefs and many desires, and they often pull us in conflicting directions. The theory of practical reason must explain the fact that desires can conflict with one another, and the fact that we can act against our all‐things‐considered judgment (weakness of will, akrasia, and incontinence). The standard explanation of these facts invokes some form of partitioning among desires. Davidson's view creates, by contrast, a partition within practical reason itself. He distinguishes between forms of rationality that are constitutive of action, and forms of rationality that are normative standard from which action can fall short. Davidson's “principle of continence,” a rule against weakness of will, is such a principle: it is required for acting well, but not for acting.
