Philip Pettit

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.

Trusting someone in an intuitive, rich sense of the term involves not just relying on that person, but manifesting reliance on them in the expectation that this manifestation of reliance will increase their reason and motive to prove reliable. Can trust between people be formed on the basis of Internet contact alone? Forming the required expectation in regard to another person, and so trusting them on some matter, may be due to believing that they are trustworthy; to believing that they seek es teem and will be rationally responsive to the good opinion communicated or promised by an act of trust; or to both factors at once. Neither mechanism can rationally command confidence, however, in the case where people are related only via the Internet. On the Internet everyone wears the ring of Gyges; everyone is invisible, in their personal identity, to others.

The desire for esteem, and the associated desire for good reputation, serve an important role in ordinary social life in disciplining interactions and supporting the operation of social norms. The fact that many Internet relations are conducted under separate dedicated e-identities may encourage the view that Internet relations are not susceptible to these esteem-related incentives. We argue that this view is mistaken. Certainly, pseudonyms allow individuals to moderate the effects of disesteem-either by changing the pseudonym to avoid the negative reputation, or by partitioning various audiences according to different audience values. However, there is every reason to believe that a good e-reputation is an object of desire for real agents. Further, although integrating one’s reputation under a single identity has some esteem-enhancing features, those features are not necessarily decisive. We explore in the paper what some of the countervailing considerations might be, by appeal to various analogies with the Internet case.

In 'The Humean Theory of Motivation' Michael Smith attempts two tasks: he offers an account of the debate about motivation between Humeans and anti-Humeans and he provides arguments that are designed to show that the Humeans win. While the paper is of great virtue in clarifying the debate, I believe that it falls short of both its goals. It does not highlight the really central issue between Humeans and anti-Humeans and it does not provide arguments which would settle that issue in favour of the Humean side.

This reply argues five points, in response to the commentaries on my book, “Made with Words”. First, that Hobbes's theory of language may have supported his materialism, as his materialism supported the theory of language. Second, that for Hobbes legal penalties as such do not take from freedom, only legal obligations. Third, that his emphasis on maker's knowledge explains his theory of a priori demonstrable knowledge and, in particular, the importance he gives to definitions. Fourth, that Hobbes's theory of the desire for power suggests, against his own strategy, that people each ought to seek the equality that goes with others not having power over them; this is the next best to the inequality a person would enjoy in having power over others. And fifth, that Hobbes's theory of freedom is inferior in a number of respects to the republican theory of freedom as non-domination that he opposed

This innovative approach to freedom starts from an account of what we mean by describing someone, in a psychological vein, as a free subject. Pettit develops an argument as to what it is that makes someone free in that basic sense; and then goes on to derive the implications of the approach for issues of freedom in political theory. Freedom in the subject is equated with the person's being fit to be held responsible and to be authorized as a partner in interaction. This book is unique among contemporary approaches - although it is true to the spirit of classical writers like Hobbes and Kant - in seeking a theory that applies to psychological issues of free agency and free will as well as to political issues in the theory of the free state and the free constitution. The driving thesis is that it is only by connecting up the different issues of freedom, psychological and political, that we can fully appreciate the nature of the questions involved, and the requirements for their resolution. The book does not not seek a comprehensive reach just for its own sake, but rather for the sake of the illumination it provides._ _ _A Theory of Freedom_ is a ground-breaking volume which will be of wide interest to scholars and students in political philosophy and political science

The question with which I shall be concerned in this paper is whether global response-dependence entails the truth of a certain noumenal form of realism: for short, a certain noumenalism. I accept that it does, at least under a plausible assumption, endorsing an argument presented by Michael Smith and Daniel Stoljar. But I try to show that, while the connection with noumenalism is undeniable, it is neither distinctive of a belief in global response-dependence nor particularly disturbing for those of us who embrace that belief.
