Review of John Burgess' and Gideon Rosen's A Subject with no Object.

Peter Abelard (1079–1142 ce) was the most wide‐ranging philosopher of the twelfth century. He quickly established himself as a leading teacher of logic in and near Paris shortly after 1100. After his affair with Heloise, and his subsequent castration, Abelard became a monk, but he returned to teaching in the Paris schools until 1140, when his work was condemned by a Church Council at Sens. His logical writings were based around discussion of the “Old Logic”: Porphyry's Isagoge, aristotle'S Categories and (...) On Interpretation and boethius'S textbook on topical inference. They comprise a freestanding Dialectica (“Logic”; probably c.1116), a set of commentaries (known as the Logica [Ingredientibus], c. 1119) and a later (c. 1125) commentary on the Isagoge (Logica Nostrorum Petititoni Sociorum or Glossulae). In a work Abelard called his Theologia, issued in three main versions (between 1120 and c.1134), he attempted a logical analysis of trinitarian relations and explored the philosophical problems surrounding God's claims to omnipotence and omniscience. The Collationes (“Debates,” also known as “Dialogue between a Christian, a Philosopher and a Jew”; probably c.1130) present a rational investigation into the nature of the highest good, in which the Christian and the Philosopher (who seems to be modeled on a philosopher of pagan antiquity) are remarkably in agreement. The unfinished Scito teipsum (“Know thyself,” also known as the “Ethics”; c.1138) analyses moral action. (shrink)

Which concepts should we use to think and talk about the world and to do all of the other things that mental and linguistic representation facilitates? This is the guiding question of the field that we call ‘conceptual ethics’. Conceptual ethics is not often discussed as its own systematic branch of normative theory. A case can nevertheless be made that the field is already quite active, with contributions coming in from areas as diverse as fundamental metaphysics and social/political philosophy. In (...) this pair of papers, we try to unify the field, reflecting on its basic nature, structure, and methodology. (shrink)

In this paper we attempt to sharpen and to provide an answer to the question of when human beings first become conscious. Since it is relatively uncontentious that a capacity for raw sensation precedes and underpins all more sophisticated mental capacities, our question is tantamount to asking when human beings first have experiences with sensational content. Two interconnected features of our argument are crucial. First, we argue that experiences with sensational content are supervenient on facts about electrical activity in the (...) cerebral cortex which can be ascertained through EEG readings. Second, we isolate from other notions of a‘functioning brain’that which is required to underpin the view that a cortex is functioning in a way which could give rise to rudimentary conscious experiences. We investigate the development in the human fetus of the anatomical and chemical pathways which underpin cortical activity and the growth and maturation of the electrical circuitry specifically associated with sensational content in adult experience. We conclude that a fetus becomes conscious at about 30 to 35 weeks after conception; an answer based on a careful analysis of EEG readings at various stages of cortical development. Finally, we survey the possible ethical ramifications of our answer. (shrink)

Recent philosophy of language has been profoundly impacted by the idea that mainstream, model-theoretic semantics is somehow incompatible with deflationary accounts of truth and reference. The present article systematizes the case for incompatibilism, debunks circularity and “modal confusion” arguments familiar in the literature, and reconstructs the popular thought that truth-conditional semantics somehow “presupposes” a correspondence theory of truth as an inference to the best explanation. The case for compatibilism is closed by showing that this IBE argument fails to rule out (...) two kinds of deflationism: the position Field famously accused Tarski of having; and a less familiar version of the view that defines reference in terms of a deflated notion of truth. Finally, the distinction between unifying and constitutive explanation is used to forestall the response that correspondence theory is literally part of mainstream semantics. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:For More than One Voice: Toward a Philosophy of Vocal ExpressionSarah K. Burgess and Stuart J. MurrayFor More than One Voice: Toward a Philosophy of Vocal Expression. Adriana Cavarero. Trans. Paul A. Kottman. Stanford: Stanford University Press, 2005. Pp. 262. $65.00, hardcover; $24.95, paperback.Adriana Cavarero's most recent book, For More than One Voice, offers the reader a critique of Western metaphysics that challenges the hegemony of speech's (...) relation to thought within politics. Revisiting Aristotle's Politics, Cavarero examines the famous definition of man as "zoon logon echon"—usually translated as "rational animal." She is critical of the tradition that renders logos here as "reason" or "rationality," modeled on the abstract and disembodied Platonic idea. Reading the Politics alongside the Poetics, she brings politics into a distinctly rhetorical sphere, and therefore figures logos as "phone semantike." In this light, man is a "speaking animal," an animal who speaks with a voice (phone) that is meaningful (semantike—an adjectival form that qualifies the voice itself). Cavarero's argument is that voice and meaning—phonic and semantic—must be sharply distinguished. The history of Western philosophy, she contends, has effaced this vital difference and focused instead on speech as a unitary phenomenon in which the vocalic and the semantic are always already joined as meaningful signification. In this way, the singularity of the vocalic itself has been elided in favor of speech that strongly privileges meaning. She therefore wishes to deliver us from language, as it were, through a recuperation of the force of the vocalic, the acoustic, the resonant and sonorous auditory quality of phone.Absent in the history of Western philosophy, this sonorous aspect of the vocalic stands as a corrective to our logocentric metaphysical tradition that singularly values the visual over the acoustic, semantic content over vocal utterances, and an abstract, anonymous "what" over a particular, embodied "who." Cavarero claims that the vocalic is an "anti-metaphysical" force that exceeds and challenges signification. In other words, the vocalic immediately communicates the uniqueness of the speaker without recourse to the signifying content of his or her speech. The voice is essentially relational—a relation that is described as "the condition of every communication.... the communicability of the communicable, or the significance of signification" (29). Indeed, for Cavarero the voice is that which "precedes, generates, and exceeds verbal communication" [End Page 166] (29–30). In this way, remarkably, Cavarero refigures the voice as a presymbolic origin that is both temporally and ontologically prior to signification, as that which is a condition of possibility for signification, and as that which is never exhausted by any signifying speech act as such.The voice is the expression of one unique, embodied individual to another. This expression, a "reciprocal invocation" founded in the sonorous, rhythmic, and resonant materiality of the voice, constitutes a "duet," a musical exchange of voices in and through which individuals mutually invoke one another. Cavarero resists inscribing such a relation within the symbolic realm; yet for her this relation is a "wordless language" that takes place in the paradigmatic scene between mother and infant. Here, in this originary scene, there is not yet the movement of language or speech as such, but the rhythm and cadence of demand and response—the voices of mother and infant that invoke one another. Drawing on Hélène Cixous's and Julia Kristeva's well-known work on the maternal chora, Cavarero demonstrates that the cadence of the "la-la melody" exchanged between mother and infant "configure[s] a reciprocal dependence" (170) that takes a structural form in the movement between demand and response.For Cavarero, the "scene of infancy" enjoys a primacy: it is both ontologically and chronologically prior to the institution of language and law. The maternal chora is figured as that which invisibly underwrites what will be understood as the law of the father—a law that is said to mark the inauguration of language. But if the law of the father is rational and semantic, the maternal should not be conceived as simply irrational and pure sound. For Cavarero, the maternal vocalic demonstrates its own reason through its rhythmic and musical resonance... (shrink)

There is a constructive method to define a structure of simple k-cyclic Post algebra of order p, L p,κ, on a given finite field F, and conversely. There exists an interpretation Ф₁ of the variety V generated by L p,κ into the variety V) generated by F and an interpretation Ф₂ of V) into V such that Ф₂Ф₁ = B for every B ϵ V and Ф₁₂ = R for every R ϵ V). In this paper we show how we (...) can solve an algebraic system of equations over an arbitrary cyclic Post algebra of order p, p prime, using the above interpretation, Gröbner bases and algorithms programmed in Maple.

Computability and Logic has become a classic because of its accessibility to students without a mathematical background and because it covers not simply the staple topics of an intermediate logic course, such as Godel's incompleteness theorems, but also a large number of optional topics, from Turing's theory of computability to Ramsey's theorem. This 2007 fifth edition has been thoroughly revised by John Burgess. Including a selection of exercises, adjusted for this edition, at the end of each chapter, it offers (...) a simpler treatment of the representability of recursive functions, a traditional stumbling block for students on the way to the Godel incompleteness theorems. This updated edition is also accompanied by a website as well as an instructor's manual. (shrink)

The question, "Which modal logic is the right one for logical necessity?," divides into two questions, one about model-theoretic validity, the other about proof-theoretic demonstrability. The arguments of Halldén and others that the right validity argument is S5, and the right demonstrability logic includes S4, are reviewed, and certain common objections are argued to be fallacious. A new argument, based on work of Supecki and Bryll, is presented for the claim that the right demonstrability logic must be contained in S5, (...) and a more speculative argument for the claim that it does not include S4.2 is also presented.

In placing education at the centre, as The Main Enterprise of the World, Philip Kitcher has undertaken a monumental task. He has come to the field of philosophy of education captivated by the importance of its substantive preoccupations for the advancement of democratic aims. Accordingly, his book argues that the most salient obstruction to preparing citizens who will contribute to society is the seeming irreconcilability of the demands of industry, on the one hand, and of students’ personal growth, on the (...) other. In spite of his desire to accommodate diverse accounts of the human good, and his recognition of the formative role of culture, broadly conceived, there are strains in his account of human fulfilment deriving from the disjunction of the self and others. It is not evident, on his Deweyan onto-epistemology, that there is adequate attention to the imprint on an individual, and on the beliefs they come to form, of proximal social groups. The nature of the balance between ‘in-group’ and ‘out-group’ influences, between those that are near and those that are far, can profoundly affect the plausibility of Kitcher's account of a socially based sense of fulfilment.

This fourth edition of one of the classic logic textbooks has been thoroughly revised by John Burgess. The aim is to increase the pedagogical value of the book for the core market of students of philosophy and for students of mathematics and computer science as well. This book has become a classic because of its accessibility to students without a mathematical background, and because it covers not simply the staple topics of an intermediate logic course such as Godel's Incompleteness (...) Theorems, but also a large number of optional topics from Turing's theory of computability to Ramsey's theorem. John Burgess has now enhanced the book by adding a selection of problems at the end of each chapter, and by reorganising and rewriting chapters to make them more independent of each other and thus to increase the range of options available to instructors as to what to cover and what to defer.

This paper considers the implications of precautionary restrictions against technologies, in the context of the potential for creating and sustaining rumours. It focuses on the restriction against mobile phone use at petrol stations, based on the rumour that a spark might cause an explosion. Rumours have been substantiated by precautionary usage warnings from mobile phone manufacturers, petrol station usage restrictions, and a general lack of technical understanding. Petrol station employees have themselves spread the rumour about alleged incidents, filling the information (...) gap about the basis for the restriction. (shrink)
