This commentary defends intentionalist accounts of self-deception against Mele by arguing that: (1) viewing self-deception on the model of other-deception is not as paradoxical as Mele makes out; (2) the paradoxes are not entailed by the view that self-deception is intentional; and (3) there are two problems for Mele's theory that only an intentionalist theory can solve.

Hilary Putnam deals in this book with some of the most fundamental persistent problems in philosophy: the nature of truth, knowledge and rationality. His aim is to break down the fixed categories of thought which have always appeared to define and constrain the permissible solutions to these problems.

Self-deception poses tantalizing conceptual conundrums and provides fertile ground for empirical research. Recent interdisciplinary volumes on the topic feature essays by biologists, philosophers, psychiatrists, and psychologists (Lockard & Paulhus 1988, Martin 1985). Self-deception's location at the intersection of these disciplines is explained by its significance for questions of abiding interdisciplinary interest. To what extent is our mental life present--or even accessible--to consciousness? How rational are we? How is motivated irrationality to be explained? To what extent are our beliefs subject to (...) our control? What are the determinants of belief, and how does motivation bear upon belief? In what measure are widely shared psychological propensities products of evolution? (shrink)

Can the existence of motivationally biased beliefs plausibly be explained without appealing to actions that are aimed at producing or protecting these beliefs? Drawing upon some recent work on everyday hypothesis testing, I argue for an affirmative answer. Some theorists have been too quick to insist that motivated belief must involve, or typically does involve, our trying to bring it about that we acquire or retain the belief, or our trying to make it easier for ourselves to believe a preferred (...) proposition—and too quick to conclude that such exercises of agency are involved in specific instances of the phenomenon. There are alternative ways to accommodate the data, and it is far from clear that the “agency view” accommodates them better. (shrink)

Deflationsism about truth is a pot-pourri, variously claiming that truth is redundant, or is constituted by the totality of 'T-sentences', or is a purely logical device (required solely for disquotational purposes or for re-expressing finitarily infinite conjunctions and/or disjunctions). In 1980, Hartry Field proposed what might be called a 'deflationary theory of mathematics', in which it is alleged that all uses of mathematics within science are dispensable. Field's criterion for the dispensability of mathematics turns on a property of theories, called (...) conservativeness. I present some technical results, some of which may be found in Tarski (1936), concerning the logical properties of truth theories; in particular, concerning the conservativeness of adding a truth theory for an object level language to any theory expressed in it. It transpires that various deflationary truth theories behave somewhat differently from the standard Tarskian truth theory. These results suggest that Tarskian theories of truth are not redundant or dispensable. Finally, I hint at an analogy between the behaviour of mathematical theories and of standard (Tarskian) theories of truth with respect to their indispensability to, as Quine would put, our 'scientific world-view'.

In the Tarskian theory of truth, the strengthened liar sentence is a theorem. More generally, any formalized truth theory which proves the full, self-applicative scheme True(“f”) f will prove the strengthened liar sentence. (This scheme is sometimes called (T-Out).).

What is truth. Paul Horwich advocates the controversial theory of minimalism, that is that the nature of truth is entirely captured in the trivial fact that each proposition specifies its own condition for being true, and that truth is therefore an entirely mundane and unpuzzling concept. The first edition of Truth, published in 1980, established itself as the best account of minimalism and as an excellent introduction to the debate for students. For this new edition, Horwich has refined and developed (...) his treatment of the subject in the light of subsequent discussions, while preserving the distinctive format that made the earlier edition so successful.

Paul Horwich gives the definitive exposition of a prominent philosophical theory about truth, `minimalism'. His theory has attracted much attention since the first edition of Truth in 1990; he has now developed, refined, and updated his treatment of the subject, while preserving the distinctive format of the book. This revised edition appears simultaneously with a new companion volume, Meaning; the two books demystify central philosophical issues, and will be essential reading for all who work on the philosophy of language.

Science Without Numbers caused a stir in 1980, with its bold nominalist approach to the philosophy of mathematics and science. It has been unavailable for twenty years and is now reissued in a revised edition with a substantial new preface presenting the author's current views and responses to the issues raised in subsequent debate.
