Bilattices, introduced by M. Ginsberg, constitute an elegant family of multiple-valued logics. Those meeting certain natural conditions have provided the basis for the semantics of a family of logic programming languages. Now we consider further restrictions on bilattices, to narrow things down to logic programming languages that can, at least in principle, be implemented. Appropriate bilattice background information is presented, so the paper is relatively self-contained.

A textbook for graduate students of philosophy, computer science, and mathematics, on various approaches to nonmonotonic logic, with emphasis on they way in which they fall into an overall pattern.

As he practices this method, what emerges through the volume is the unity of McDowell’s own views.

Brandom’s attempt to motivate inferentialism is found wanting on a number of grounds, including a skepticism about how much recommendation for inferentialism can be derived from the evident unsatisfactoriness of the representationalism Brandom contrasts it with, which seems to be a straw man. Brandom’s appeal to authorities falls flat; in particular, his reading of Frege’s early work as inferentialist in Brandom’s sense is a misinterpretation. Given the programmatic character of Brandom’s recommendation for inferentialism, the quality of the motivation he offers (...) for it matters more than he has acknowledged. (shrink)

1. I am going to work with an idea from Sellars, that knowledge—at least as enjoyed by rational animals—is a certain sort of standing in the space of reasons. My concern is a familiar philosophical dialectic, which I shall approach in terms of what happens to the Sellarsian idea when the image of standings in the space of reasons undergoes a certain deformation. That it is a deformation is something we can learn from how unsatisfactory the familiar dialectic is.

In “Knowledge and the Social Articulation of the Space of Reasons,” Robert Brandom reads my “Knowledge and the Internal” as sketching a position that, when properly elaborated, opens into his own social-perspectival conception of knowledge . But this depends on taking me to hold that there cannot be justification for a belief sufficient to exclude the possibility that the belief is false. And that is exactly what I argued against in “Knowledge and the Internal.” Seeing that P constitutes falsehood-excluding justification (...) for believing that P. That should seem common sense, but it is made unavailable by the inferentialist conception of justification that Brandom takes for granted. So far from realizing my aims, Brandom’s social-perspectival conception of knowledge is squarely in the target area of my argument in “Knowledge and the Internal,” which I restate here so as to bring that out.

How do rational minds make contact with the world? The empiricist tradition sees a gap between mind and world, and takes sensory experience, fallible as it is, to provide our only bridge across that gap. In its crudest form, for example, the traditional idea is that our minds consult an inner realm of sensory experience, which provides us with evidence about the nature of external reality. Notoriously, however, it turns out to be far from clear that there is any viable (...) conception of experience which allows it to do the job. The original problem is to show that thought is rationally constrained by external reality. If sensory experience is to provide the solution--in particular, if it is to provide the answer to sceptical challenges--it must therefore meet two criteria. First, it must itself be `receptive'--i.e., appropriately constrained by external reality. Second, it must be the kind of thing that can enter into a logical or rational relationship with belief--it must already be `conceptual,' in other words. In arguing against the idea that anything could serve both roles, Wilfred Sellars termed this conception of experience "the Myth of the Given.". (shrink)

A work in the history of systematic philosophy that is itself animated by a systematic philosophic aspiration, this book by one of the most prominent American ...

In “Knowledge and the Internal” John McDowell presents a deep and interesting argument. I think everything he says is true and important. Still, there are a number of points that bear expanding on in order to be properly understood. So I want to say something about his point of departure: the idea of standings in the space of reasons. And I want to fill in further the picture at which he finally arrives, by saying how I think we ought to (...) understand knowledge as a standing in the space of reasons, once we have freed ourselves from a prevalent deformed conception of that space. McDowell’s strategy is to show that that conception of the space of reasons is inadequate—that it deserves to be called a ‘deformation’—by showing that it leaves no room for anything recognizable as knowledge. I’ll try to reconstruct that argument by showing what it looks like in the context of a crucial dimension of the space of reasons that McDowell never mentions: its essentially social articulation. The effect of this supplementation, I think, is not to turn a bad argument into a good one, but to turn what is already a good argument into one that further illuminates the phenomena with which it deals.

Wilfrid Sellars ranks as one of the leading critics of empiricism—a philosophical approach to knowledge that seeks to ground it in human sense experience. Robert Brandom clarifies what Sellars had in mind when he talked about moving analytic philosophy from its Humean to its Kantian phase and why such a move might be of crucial importance today.

Extending the project of analysis -- Elaborating abilities : the expressive role of logic -- Artificial intelligence and analytic pragmatism -- Modality and normativity : from Hume and Quine to Kant and Sellars -- Incompatibility, modal semantics, and intrinsic logic -- Intentionality as a pragmatically mediated semantic relation -- Afterword : philosophical analysis and analytic philosophy.

Robert Brandom's latest book, the product of his John Locke lectures in Oxford in 2006, is a return to the philosophy of language and is easily read as a continuation and development of the views defended in Making it Explicit. The text of the lectures is presented much as they were delivered, but it contains an ‘Afterword’ of more than 30 pages which responds to questions raised when he gave the lectures, and also when they were subsequently delivered in Prague (...) the following year. The published text also contains relatively technical appendices to two of the lectures.The individual lectures engage with some important and difficult issues, often ones that were explored in detail in the earlier book. However, these discussions are located within a broader meta-philosophical context, and it says something about the abstract and difficult character of these views that they provide the main subject matter of the Afterword. This framework affects how we should understand the relations between this book and Making It Explicit too. Although most of the detailed discussions happily belong within the general project of the earlier book, they are offered as illustrations of a framework that is independent of this project. Indeed, Brandom suggests that defenders of the semantic views of David Lewis, for example, could embrace his main message as well as those who favour Brandom's own form of pragmatism.Neo-pragmatist philosophers such as Brandom's teacher, Richard Rorty, often present themselves as rejecting the analytic tradition in philosophy. When Brandom describes the ‘pragmatist challenge’ to the ‘classical project of analysis’, he appeals to the criticisms found in the work of Wittgenstein and Sellars that are often appealed to by the critics of the analytic tradition. The message of the new book is that the views he has built on this …. (shrink)

An graduate level introduction to nonmonotonic reasoning, emphasizing structures and spirit common to different formulations, with exercises.

In this new book, John McDowell builds on his much discussed Mind and World—one of the most highly regarded books in contemporary philosophy.

This book introduces an important group of logics that have come to be known under the umbrella term 'susbstructural'. Substructural logics have independently led to significant developments in philosophy, computing and linguistics. _An Introduction to Substrucural Logics_ is the first book to systematically survey the new results and the significant impact that this class of logics has had on a wide range of fields.The following topics are covered: * Proof Theory * Propositional Structures * Frames * Decidability * Coda Both (...) students and professors of philosophy, computing, linguistics, and mathematics will find this to be an important addition to their reading.

In spite of a powerful tradition, more than two thousand years old, that in a valid argument the premises must be relevant to the conclusion, twentieth-century logicians neglected the concept of relevance until the publication of Volume I of this monumental work. Since that time relevance logic has achieved an important place in the field of philosophy: Volume II of Entailment brings to a conclusion a powerful and authoritative presentation of the subject by most of the top people working in (...) the area. Originally the aim of Volume II was simply to cover certain topics not treated in the first volume--quantification, for example--or to extend the coverage of certain topics, such as semantics. However, because of the technical progress that has occurred since the publication of the first volume, Volume II now includes other material. The book contains the work of Alasdair Urquhart, who has shown that the principal sentential systems of relevance logic are undecidable, and of Kit Fine, who has demonstrated that, although the first-order systems are incomplete with respect to the conjectured constant domain semantics, they are still complete with respect to a semantics based on "arbitrary objects." Also presented is important work by the other contributing authors, who are Daniel Cohen, Steven Giambrone, Dorothy L. Grover, Anil Gupta, Glen Helman, Errol P. Martin, Michael A. McRobbie, and Stuart Shapiro. Robert G. Wolf's bibliography of 3000 items is a valuable addition to the volume. (shrink)

1. I take my question from Robert Brandom, who remarks in his Study Guide (167): “The title of this essay is ‘Empiricism and the Philosophy of Mind,’ but Sellars never comes right out and tells us what his attitude toward empiricism is.”1 Brandom goes on to discuss a passage that might seem to indicate a sympathy for empiricism on Sellars’s part, but he dismisses any such reading of it. (I shall come back to this.) He concludes: “Indeed, we can see (...) at this point [he has reached §45] that one of the major tasks of the whole essay is to dismantle empiricism” (168). I am going to argue that this claim is quite wrong. To do Brandom justice, I should note that when he defends his claim, what he mentions is, specifically, traditional empiricism. But he nowhere contemplates a possibility left open by this more detailed (and correct) specification of Sellars’s target — the possibility that Sellars might be aiming to rescue a non-traditional empiricism from the wreckage of traditional empiricism, so that he can show us how to be good empiricists. I think that is exactly what Sellars aims to do in this essay. (shrink)
