Warren Goldfarb, Deductive Logic, Hackett Publishing Company, 2003.    : 0872206602. Deductive Logic is an introductory textbook in formal logic. The book is divided into four parts covering truth-functional logic, monadic quantifi- cation, polyadic quantification and names and identity, and there are exercises for all these topics at the end of the book. In the truth-functional logic part, the reader learns to produce paraphrases of English statements and arguments in logical notation, then about the semantic properties of (...) such paraphrased statements and arguments, such as satisfiability, implication and equivalence and finally there is an axiomatic proof method and some important extras such as disjunctive normal form and expressive adequacy. Parts two and three mirror this analysis/assessment/reflection structure for monadic and polyadic quantification, though this time the proof system is a natural deduction one, and part three contains a completeness proof for that system. The fourth part of the book introduces names, the identity predicate and descriptions and examines the additional expressive power which these provide. I do not think there should be any doubt that this is an excellent book; it presents the essential topics of a first logic course with accuracy, clarity and attention to detail, and it makes material that can be confusing the first time round—say, the translation of conditionals—transparent and easy to understand. But there are a lot of good introductory logic textbooks out there, so I will say something about how it resembles and differs from some other books, and then discuss one minor irritation with this one.

Deductive Logic is an introductory textbook in formal logic. The book is divided into four parts covering (i) truth-functional logic, (ii) monadic quantifi- cation, (iii) polyadic quantification and (iv) names and identity, and there are exercises for all these topics at the end of the book. In the truth-functional logic part, the reader learns to produce paraphrases of English statements and arguments in logical notation (this subsection is called “analysis”), then about the semantic properties of such paraphrased statements and arguments, (...) such as satisfiability, implication and equivalence (“logical assessment”) and finally (“reflection”) there is an axiomatic proof method and some important extras such as disjunctive normal form and expressive adequacy. Parts two and three mirror this analysis/assessment/reflection structure for monadic and polyadic quantification, though this time the proof system is a natural deduction one, and part three contains a completeness proof for that system. The fourth part of the book introduces names, the identity predicate and descriptions and examines the additional expressive power which these provide. (shrink)

In a recent article, John McDowell has criticised Warren Goldfarb for attributing an anti-realist conception of linguistic understanding to Wittgenstein. 1 I argue that McDowell is right to reject Goldfarb's anti- realism, but does so for the wrong reasons. I show that both Goldfarb's and McDowell's interpretations are vitiated by the fact that they do not pay attention to Wittgenstein's positive claims about understanding, in particular his claim that understanding is a kind of ability. The cause of this oversight (...) lies in their endorsement of an excessively anti-systematic or “therapeutic” reading of Wittgenstein. (shrink)

Once upon a time, logical conventionalism was the most popular philosophical theory of logic. It was heavily favored by empiricists, logical positivists, and naturalists. According to logical conventionalism, linguistic conventions explain logical truth, validity, and modality. And conventions themselves are merely syntactic rules of language use, including inference rules. Logical conventionalism promised to eliminate mystery from the philosophy of logic by showing that both the metaphysics and epistemology of logic fit into a scientific picture of reality. For naturalists of all (...) stripes, this was paradise. Alas, paradise was lost. By the end of the twentieth century, logical conventionalism had been almost universally abandoned. But more recently, it has been revitalized. This chapter provides an overview of logical conventionalism and its history, clears away misunderstandings, and briefly responds to both the canonical objections to conventionalism (from Quine, Dummett, Boghossian, and many others) as well as new objections (from Field and Golan). From paradise lost, to paradise regained: logical conventionalism is back. (shrink)

In this article, I show how Bruschi’s Le matérialisme politique de Louis Althusser offers, against all attempts conjure up a self-generating general theory of history, a reconstruction of Althusser’s work that shows how its systematicity relies upon the unfinished, incomplete and provisional character of scientific research, always subject to constant rectification. I then claim that, from the conceptualisa-tion of the reproduction of the mode of production as dependent upon the singularity of the con-juncture, to the theorisation of the encounter as (...) the source of historical necessity, this constant re-working is crucial to Althusser’s ability to grasp the reality of class struggle.

This book is the first extensive treatment of Husserl's phenomenology of time-consciousness. Nicolas de Warren uses detailed analysis of texts by Husserl, some only recently published in German, to examine Husserl's treatment of time-consciousness and its significance for his conception of subjectivity. He traces the development of Husserl's thinking on the problem of time from Franz Brentano's descriptive psychology, and situates it in the framework of his transcendental project as a whole. Particular discussions include the significance of time-consciousness for (...) other phenomenological themes: perceptual experience, the imagination, remembrance, self-consciousness, embodiment, and the consciousness of others. The result is an illuminating exploration of how and why Husserl considered the question of time-consciousness to be the most difficult, yet also the most central, of all the challenges facing his unique philosophical enterprise"--Provided by publisher.

The ancient philosophical school of Epicureanism tried to argue that death is "nothing to us." Were they right? James Warren provides a comprehensive study and articulation of the interlocking arguments against the fear of death found not only in the writings of Epicurus himself, but also in Lucretius' poem De rerum natura and in Philodemus' work De morte. These arguments are central to the Epicurean project of providing ataraxia (freedom from anxiety) and therefore central to an understanding of Epicureanism (...) as a whole. They also offer significant resources for modern discussions of the value of death--one which stands at the intersection of metaphysics and ethics. If death is the end of the subject, and the subject can not be benefited nor harmed after death, is it reasonable nevertheless to fear the ceasing-to-be? If the Epicureans are not right to claim that the dead can neither be benefited nor harmed, what alternative models might be offered for understanding the harm done by death and do these alternatives suffer from any further difficulties? The discussion involves consideration of both ethical and metaphysical topics since it requires analysis not only of the nature of a good life but also the nature of personal identity and time. A number of modern philosophers have offered criticisms or defences of the Epicureans' views. Warren explores and evaluates these in the light of a systematic and detailed study of the precise form and intention of the Epicureans' original arguments. Warren argues that the Epicureans also were interested in showing that mortality is not to be regretted and that premature death is not to be feared. Their arguments for these conclusions are to be found in their positive conception of the nature of a good and complete life, which divorce the completeness of a life as far as possible from considerations of its duration. Later chapters investigate the nature of a life lived without the fear of death and pose serious problems for the Epicureans being able to allow any concern for the post mortem future and being able to offer a positive reason for prolonging a life which is already complete in their terms.

Because of the “all-or-none” character of nervous activity, neural events and the relations among them can be treated by means of propositional logic. It is found that the behavior of every net can be described in these terms, with the addition of more complicated logical means for nets containing circles; and that for any logical expression satisfying certain conditions, one can find a net behaving in the fashion it describes. It is shown that many particular choices among possible neurophysiological assumptions (...) are equivalent, in the sense that for every net behaving under one assumption, there exists another net which behaves under the other and gives the same results, although perhaps not in the same time. Various applications of the calculus are discussed. (shrink)

Marxism's collapse in the twentieth century profoundly altered the style and substance of Western European radical thought. To build a more robust form of democratic theory and action, prominent theorists moved to reject revolution, abandon class for more fragmented models of social action, and elevate the political over the social. Acknowledging the constructedness of society and politics, they chose the "symbolic" as a concept powerful enough to reinvent leftist thought outside a Marxist framework. Following Maurice Merleau-Ponty's Adventures of the Dialectic, (...) which reassessed philosophical Marxism at mid century, Warren Breckman critically revisits these thrilling experiments in the aftermath of Marxism. The post-Marxist idea of the symbolic is dynamic and complex, uncannily echoing the early German Romantics, who first advanced a modern conception of symbolism and the symbolic. Hegel and Marx denounced the Romantics for their otherworldly and nebulous posture, yet post-Marxist thinkers appreciated the rich potential of the ambiguities and paradoxes the Romantics first recognized. Mapping different ideas of the symbolic among contemporary thinkers, Breckman traces a fascinating reflection of Romantic themes and resonances, and he explores in depth the effort to reconcile a radical and democratic political agenda with a politics that does not privilege materialist understandings of the social. Engaging with the work of Claude Lévi-Strauss, Cornelius Castoriadis, Claude Lefort, Marcel Gauchet, Ernesto Laclau, Chantal Mouffe, and Slavoj Žižek, Breckman uniquely situates these important theorists within two hundred years of European thought and extends their profound relevance to today's political activism.

In his arguments that science itself can answer moral questions, Sam Harris often appeals to our intuitions about the badness of suffering. If we share these intuitions, Harris argues, we’ve taken a significant step in conceding to a basically utilitarian worldview. In this chapter, I critically assess Harris’ arguments and find them deeply wanting.

Writings by a thinker—a psychiatrist, a philosopher, a cybernetician, and a poet—whose ideas about mind and brain were far ahead of his time. Warren S. McCulloch was an original thinker, in many respects far ahead of his time. McCulloch, who was a psychiatrist, a philosopher, a teacher, a mathematician, and a poet, termed his work “experimental epistemology.” He said, “There is one answer, only one, toward which I've groped for thirty years: to find out how brains work.” Embodiments of (...) Mind, first published more than fifty years ago, teems with intriguing concepts about the mind/brain that are highly relevant to recent developments in neuroscience and neural networks. It includes two classic papers coauthored with Walter Pitts, one of which applies Boolean algebra to neurons considered as gates, and the other of which shows the kind of nervous circuitry that could be used in perceiving universals. These first models are part of the basis of artificial intelligence. Chapters range from “What Is a Number, that a Man May Know It, and a Man, that He May Know a Number,” and “Why the Mind Is in the Head,” to “What the Frog's Eye Tells the Frog's Brain” (with Jerome Lettvin, Humberto Maturana, and Walter Pitts), “Machines that Think and Want,” and “A Logical Calculus of the Ideas Immanent in Nervous Activity” (with Walter Pitts). Embodiments of Mind concludes with a selection of McCulloch's poems and sonnets. This reissued edition offers a new foreword and a biographical essay by McCulloch's one-time research assistant, the neuroscientist and computer scientist Michael Arbib. (shrink)

Warren Quinn was widely regarded as a moral philosopher of remarkable talent. This collection of his most important contributions to moral philosophy and the philosophy of action has been edited for publication by Philippa Foot. Quinn laid out the foundations for an anti-utilitarian moral philosophy that was critical of much contemporary work in ethics, such as the anti-realism of Gilbert Harman and the neo-subjectivism of Bernard Williams. Quinn's own distinctive moral theory is developed in the discussion of substantial, practical (...) moral issues. For example, there are important pieces here on the permissibility of abortion, the justification of punishing criminals when no particular good seems likely to result, and on the distinction between killing and allowing to die, a distinction crucial to the subject of euthanasia and other topics in medical ethics. The volume would be ideally suited to upper-level undergraduate courses and graduate seminars on the foundations of ethics. (shrink)

As grandes epidemias de peste que atingiram ao longo de muitos séculos os ingleses, refletiram mudanças importantes para os conhecimentos de cada período histórico. Esse artigo busca unir duas extremidades de um decorrer de grandes catástrofes epidemiológicas na Inglaterra, com um olhar especial à populosa Londres, começando com a primeira entrada da peste bubônica na cidade, em 1348, e seu provável último grande surto, em 1665. Os dois episódios tocados aqui são apresentados sob a perspectiva das novidades, semelhanças e diferenças (...) entre essas duas pontas da história, passando pelas novas respostas da medicina no século XIV e os princípios de uma ‘aritmética política’ no século XVII. Para esse fim, são de extrema importância diferentes fontes, como as inúmeras cópias do tratado médico de John de Burdeaux, escritos a partir de 1390, e o Observations de John Graunt, publicado a partir de 1662.

Estudos recentes vêm revisando a composição da literatura que, ao longo do século XVIII serviu como base às ciências em território britânico. Segundo esses estudos, os seiscentistas de fala inglesa dedicaram-se a duas linhagens de texto, originadas em concepções de ciência muito distintas. Uma dessas linhagens tinha como fonte principal a antiga “literatura do segredo” que incluía desde velhos e sigilosos manuais de ofício até os milenares e proibidos tratados de hermética, literatura antes reservada a poucos. Diferente dessa, a outra (...) ]inhagem de textos surgia como um direto da proposta baconiana para a nova ciência: um saber elaborado por muitos e ao alcance de todos. Exemplos conhecidos dessa linhagem são os livros de divulgação utilizados pelos comenianos ingleses ou mesmo os relatórios, atas e memórias das sociedades científicas, geradores dos primeiros embriões de periódicos dedicados às ciências. Todavia, sob essa aparente contraposição das duas linhagens, há indícios de um profícuo diálogo - expresso sobretudo na correspondência e diários pensadores da época. (shrink)

This paper distinguishes four senses of naturalism: reductive physicalism; a naturalism that departs from what Thompson calls “natural-historical judgments”; a naturalism that recognizes that physical nature is located within the space of reasons; and a phenomenological naturalism that shifts the focus to the “natural” experiences of subjects who encounter the world. The paper argues for a “phenomenological neo-Aristotelianism” that accounts both for the internal justification of our first-order moral experience and the need for a broader grounding in a universalistic account (...) of the goods of agency.

The Epicurean philosophical system has enjoyed much recent scrutiny, but the question of its philosophical ancestry remains largely neglected. It has often been thought that Epicurus owed only his physical theory of atomism to the fifth-century BC philosopher Democritus, but this study finds that there is much in his ethical thought which can be traced to Democritus. It also finds important influences on Epicurus in Democritus' fourth-century followers such as Anaxarchus and Pyrrho, and in Epicurus' disagreements with his own Democritean (...) teacher Nausiphanes. The result is not only a fascinating reconstruction of a lost tradition, but also an important contribution to the philosophical interpretation of Epicureanism, bearing especially on its ideal of tranquillity and on the relation of ethics to physics.
