This paper contrasts a picoeconomic approach to theexplanation of akrasia with Davidson's divided-mind approach and defends theformer in a wider context. The distinctive merits of a picoeconomic model of mindlie in the following aspects: First, it relies on a scientifically well-groundeddiscovery about motivational dynamics of animals for its explanation of preference change,which elucidates or materializes some philosophers' speculations both about thepossible mismatch between valuation and motivation and about the relevance of temporalfactors to akrasia. Second, it grounds the necessity of endogenous (...) higher-order constraints,expressible in forms of judgment, in an intrapersonal dynamic process of interactivefirst-order temporary preferences. Thus the motivational basis for the normativeconstruction of the rationality of `best judgment' can also be illuminated with this model. (shrink)

Although irrationality always presupposes rationality, I think there are good arguments to claim that sometimes rationality presupposes irrationality.This paper tries to show how irrational action can support rationality in two ways: it can develop and preserve rationality. I also argue that sometimes the development and the conservation of rationality can only be realized by irrational action.

Akrasia is both an intentional and an irrational phenomenon. These two characteristics can be reconciled by a careful reconstruction of practical reasoning. I undertake this task along Davidsonian lines, arguing against his critics that the notion of unconditional judgment is the key to an adequate account of akrasia. Unless akrasia is conceived as a failure of the agent to form an unconditional judgment that conforms to her best judgment "all things considered," the intentionality of akrasia is lost. Likewise, I show (...) how practical and theoretical reasoning concur in the production of action, and why akrasia is a problem for the philosophy of action before being a problem for moral philosophy.

The occurrence or apparent occurrence of incontinent actions challenges several influential views in ethics and the philosophy of mind, e.g., Hare's prescriptivism and the Socratic idea that we always act in the light of the imagined greatest good. It also raises, as I shall explain, an interesting and instructive problem for proponents of causal theories of action. But whereas Socrates and Hare attempt to avoid the difficulties with which akrasia confronts them by denying - wrongly, I shall argue - that (...) there are akratic actions ([15], 352a-358d; [13], Ch. 5), the causal theorist need not take this unhappy tack. In this paper I shall argue that the truth of a causal theory of action (CTA) is compatible with the occurrence of akratic actions and, in particular, with akratic actions against what I shall call a "here-and-now" intention - i.e., an intention of the agent to do an A here and now. I shall suggest that akratic actions of this type plainly do occur, and I shall attempt to explain how they might be accommodated by a causal theory of action. (shrink)
