The market is traditionally hailed as the very exemplar of a system under which people enjoy freedom, in particular the negative sort of freedom associated with liberal and libertarian thought: freedom as noninterference. But how does the market appear from the perspective of a rival conception of freedom (freedom as non-domination) that is linked with the Roman and neo-Roman tradition of republicanism? The republican conception of freedom argues for important normative constraints on property, exchange, and regulation, without supporting extremes to the effect that ‘property is theft’ or ‘taxation is theft’ or anything of that kind. It does not cast a cold eye on commerce; it merely provides an alternative view of the attractions

Examines what is necessary for a group to constitute an agent that can display akrasia, and what steps such a group might take to establish self‐control. The topic has some interest in itself, and the discussion suggests some lessons about how we should think of akrasia in the individual as well as in the collective case. Under the image that the lessons support, akrasia is a sort of constitutional disorder: a failure to achieve a unity projected in the avowal of agency. This image fits well with the constitutional model of the soul in Plato's Republic.

This essay outlines some of the main issues that arise in the theory of freedom and, in particular, those that divide the liberal conception of freedom as non-interference from the republican conception of freedom as non-domination. It goes on to explore the idea that discourse theory provides reasons for favouring the republican conception. Discourse theory is taken for these purposes to be a theory that subsumes, but goes beyond decision theory. It accepts the decision-theoretic view that human agents are moved by beliefs and desires that, on the whole, are rationally maintained and rationally issued in action. But it adds the further, crucial assumption that human beliefs and desires are shaped under the transformative influence of discursive argument and exchange

Allan Gibbard’s strategy in his new book is to begin by describing a psychology of thinking and planning that certain agents might instantiate, then to argue that this psychology involves an ‘expressivism’ about thought that bears on what to do, and, finally, to try to show that ascribing that same psychology to human beings would explain the way we deploy various concepts in practical and normative deliberation. The idea is to construct an imaginary normative psychology, purportedly conforming to expressivist specifications, and then to campaign for the hypothesis that that psychology is ours and that we ourselves conform to those specifications. The upshot is an original and intriguing argument for the claim that ‘expressivism’, as Gibbard understands it, is sound. There is more in the book than that bare argument. Filling out the strategy pursued, for example, the volume contains useful discussions of a number of current debates (chs 2, 12), an enlightening argument that the strategy survives the introduction of the notion that a concept can have a character distinct from its content (ch. 6), and an extended set of reflections on how far the point of view defended leaves room for the idea of gaining normative knowledge (pt. 4). But I shall ignore those aspects of the book in this commentary; the focus is on its central argument. My approach will be to reconstuct the main stages in the Aufbau of our normative psychology that Gibbard provides, emphasizing some crucial points that are passed over rather quickly, and then to suggest on the basis of this reconstruction that the more natural lesson to derive is not an expressivist one. Although I break with Gibbard in that way, however, I have great admiration for the book. Thinking How to Live is a sharp, fresh and invigorating treatment of the main issues of metaethics
