To be pertinent to democratic practice, collective choice functions need not apply to all possible constellations of individual preference, but only to those that are humanly possible in an appropriate sense. The present paper develops a theory of humanly possible preference within the context of the mathematical theory of learning. The theory of preference is then exploited in an attempt to resolve Arrow's voting paradox through restriction of the domain of majoritarian choice functions.

We focus on a particular class of computably enumerable degrees, the array noncomputable degrees defined by Downey, Jockusch, and Stob, to answer questions related to lattice embeddings and definability in the partial ordering of c. e. degrees under Turing reducibility. We demonstrate that the latticeM5 cannot be embedded into the c. e. degrees below every array noncomputable degree, or even below every nonlow array noncomputable degree. As Downey and Shore have proved that M5 can be embedded below every nonlow2 (...) degree, our result is the best possible in terms of array noncomputable degrees and jump classes. Further, this result shows that the array noncomputable degrees are definably different from the nonlow2 degrees. We note also that there are embeddings of M5 in which all five degrees are array noncomputable, and in which the bottom degree is the computable degree 0 but the other four are array noncomputable.

We use some simple facts about the wtt-degrees of r.e. sets together with a construction to answer some questions concerning the join and meet operators in the r.e. degrees. The construction is that of an r.e. Turing degree a with just one wtt-degree in a such that a is the join of a minimal pair of r.e. degrees. We hope to illustrate the usefulness of studying the stronger reducibility orderings of r.e. sets for providing information about Turing reducibility.

In lieu of an abstract, here is a brief excerpt of the content:Kenneth Burke, John Dewey, and the Pursuit of the PublicPaul StobIn Deliberation Day, Bruce Ackerman and James Fishkin argue for the creation of a national holiday, "Deliberation Day," in which citizens come together over a two-day period in their local schools and community centers to deliberate over the merits of presidential candidates and their platforms (Ackerman and Fishkin 2004). While Ackerman and Fishkin propose that the government pay each (...) citizen a $150 stipend for voluntary participation, the purpose is not so much to monetarily to reward citizens for "showing up" as it is to foster an enriched civic culture that would send shockwaves through America's political infrastructure: "If Deliberation Day succeeded, everything else would change: the candidates, the media, the activists, the interest groups, the spin doctors, the advertisers, the pollsters, the fund raisers, the lobbyists, the political parties. All would have no choice but to adapt to a more attentive and informed public" (3). The task of Deliberation Day would be to create a new social context in which citizens could become enlightened through public participation. As the authors conclude the book, "We can, through an act of political imagination, create new institutions for redeeming the ancient promise of democratic citizenship. Ordinary men and women need not be the hapless playthings of the powerful. They can and must find new ways to hold their leaders to account, and redeem their dignity as human beings by responsibly shaping their collective destiny" (219).Ackerman and Fishkin's proposal is indeed filled with political imagination. I bring their proposal to light not to critique the possibilities and limitations of Deliberation Day, but to understand the way in which the authors understand "the public." At the bottom, what the polity needs, Ackerman and Fishkin believe, is a public space dedicated to the reinvigoration [End Page 226] of political culture. It is not that the citizenry is incapable of hammering out intelligent political solutions, but that it needs access to social contexts that facilitate deliberation and the emergence of a common good. To foster a culture of political intelligence, the public needs only the chance to enter the forums that will facilitate thorough, cooperative political decision-making.Ackerman and Fishkin are not alone in calling for access to or creation of these types of forums. Habermas's bourgeois public sphere—a public space in which citizens could come together and rationally debate the activities of the state—essentially represents the evolution of a context, a social space, a public arena (Habermas 1989). The bourgeois public sphere is meant to be egalitarian, providing citizens a forum in which to debate openly and foster a common political consciousness.1 But this sphere has proved problematic for a number of scholars. Oskar Negt and Alexander Kluge (1993), for example, propose a proletarian public sphere to counter capitalism's socioeconomic domination over public resources. Joan Landes (1988) argues that the bourgeois public sphere entails male domination in public life, to the exclusion of women. Nancy Fraser (1992) builds on the feminist critique by adopting the term "counterpublics," collectives of citizens—women, peasants, the working class, and other groups demarcated by issues of race, gender, and ethnicity—that arise in reaction to the dominant public sphere.2In the introduction to Counterpublics and the State (2001), Robert Asen and Daniel Brouwer argue that critiques of the bourgeois public sphere specifically and public sphere theory generally amount to three "reconfigurations" in the way in which scholars think of the public. First, scholars have come to recognize the existence and interaction of multiple public spheres. Second, they have come to acknowledge permeable boundaries of access to the multiple public spheres. Third, scholars have come to recognize the dynamic role of the state in shaping public discourse. One considerable result of these three reconfigurations is an increasing recognition of the political divisions that permeate society (Asen and Brouwer 2001, 17-25).If Asen and Brouwer are right, and I think they are, these three reconfigurations represent the general thrust of contemporary public sphere scholarship, including as it is understood among communication scholars.3 And however diverse such scholarship may be, a few common themes seem to recur across...

In lieu of an abstract, here is a brief excerpt of the content:"Terministic Screens," Social Constructionism, and the Language of Experience:Kenneth Burke's Utilization of William JamesPaul StobKenneth Burke's influence on various academic disciplines is clear in the number of books and articles published annually on his thought. It is also clear insofar as academics continue to turn to his work for insights on handling scholarly problems. That is to say, not only do we explore the dimensions of his work, we (...) also bring it to bear on current disputes in the hopes of clarifying or moving past the issues we face. His thought, in short, has a currency that transcends its historical period. "As we meet new challenges that echo the past," writes Ross Wolin, "Burke's inquiries into meaning, orientation, faction, communication, and rhetoric are as urgent today as when Burke raised them long ago and for decades after."1By bringing the terms of Burke's work to bear on current disputes, we connect him to the vocabularies and discourses that surround us. His thought becomes familiar through the lenses we employ, as we intermix his ideas with our own terminology and see his work through the language of our discussions. One example of this phenomenon is the way scholars have been describing Burke's philosophical outlook. Burke's thought, we are told, is that of a social constructionist. Edward Schiappa, for example, concludes that Burke gives us a view of the world as intersubjectively created: "Our understanding is social in the sense that our concepts are human-made and are part of a shared language. Our understanding is [End Page 130] constructed in the sense that our claims, interpretations, and orientations constitute 'conceptual fabrics' that weave together contingent sets of beliefs and social practices."2 Paul Jay turns the sentiment into a more explicitly epistemological point: "The most radical aspect of Burke's evolving theory of language at this time is his recognition that language—inherently metaphorical—constructs rather than reflects knowledge."3 James Chesebro highlights social constructionism as one of the hallmarks of Burke's dramatism: "For Burke, the realm of symbol-using is unique to the human being. Symbol-using is a solely conventional, arbitrary, and social process. It allows human beings to become self-conscious, create motives independently of physical phenomena, and ultimately to create social constructions of reality."4 Dennis Ciesielski argues that Burke's "terministic screens" define "base reality into truth-systems unique to each respective discourse community and impl[y] a neo-pragmatic, social constructionist pattern for the making of meaning."5 Finally, Robert Wess characterizes Burke's entire career as the evolution from a materialist, biological-essentialist view of the human self to a social constructionist view.6Generally speaking, "social constructionism" is a metaphor that attempts to capture the way Burke viewed the nature of the world and the function of language therein. It suggests that symbols, terms, and language form the building blocks, the bricks and mortar, of the structures of our collective life. We employ symbols that construct our social realities, similar to the way a contractor employs the materials and labor that construct a house. Consequently, the realities we face are not inherent in nature but are built up discursively and can therefore be reconstructed as we alter our discursive practices.7The social construction metaphor positions Burke's philosophical out-look in terms that are familiar to us, though not necessarily familiar to him. That is to say, the label of social constructionist is recent, and it comes not from Burke's work but from intellectual developments after he wrote the bulk of his corpus.8 We apply it to him retroactively, meshing together his intellectual milieu with our own. And as Ian Hacking reminds us, "The phrase has become code. If you use it favorably, you deem yourself rather radical. If you trash the phrase, you declare that you are rational, reasonable, and respectable."9Labeling Burke a social constructionist wraps his thought in a current metaphor, merging his perspective with a vocabulary that was not part of his project. While such a merger is not necessarily a bad thing—to some degree the process is inevitable10—a certain danger... (shrink)

Twenty years ago, even ten years ago, one might have begun an essay about the intersection of pragmatism and rhetoric by lamenting the dearth of scholarship on the subject. Today, no such lamentations are needed. The past decade has seen an explosion of interest in the way pragmatism and rhetoric can profitably inform each other. Offering everything from formulations of pragmatist rhetorical theory (Mailloux 1998; Schollmeier 2002; Danisch 2007; Crick 2010) to explorations of pragmatist methodology in the study of rhetorical (...) texts (Stroud 2009a; Stroud 2010) to analyses of what individual pragmatists have contributed to the history of rhetoric (Asen and Brouwer 2003; Asen 2003; Finnegan 2003; Greene 2003; Stob ..

Over the last decades, curator Nicolas Bourriaud has drawn significant inspiration for his writings on contemporary art from the theories of the Situationist International (SI), an avant-garde group in existence from 1957 until 1972. Mischaracterizing the SI’s concepts of the situation, détournement, and the dérive, Bourriaud claims to update these concepts with concepts of his own: relational aesthetics, detourage, and radicant aesthetics. This article identifies such misrepresentations and highlights the differences between Bourriaud’s paradigms and those of the SI. This contextual (...) restitution also provides an opportunity to examine Bourriaud’s general methodology of substituting conceptual formalism for art historical theory. Bourriaud’s publications repeatedly claim a historical materialist perspective on aesthetics, only to eventually eliminate this perspective; his use and abuse of Situationist theory is the foundational example for this pattern. More than the artworks showcased in Bourriaud’s exhibitions and referenced in his publications, his artistic paradigms describe and delineate his own philosophical sleight of hand. (shrink)

During his long career, John Dewey produced an almost endless number of pages of dense philosophical prose, giving those interested in his work plenty to do. Even scholars of rhetoric have found a host of reasons to return to Dewey’s corpus, despite the fact that Dewey himself seemed, at best, uninterested in rhetoric. Two recent works—Robert Danisch’s Pragmatism, Democracy, and the Necessity of Rhetoric and Nathan Crick’s Democracy and Rhetoric: John Dewey on the Arts of Becoming—have already fruitfully mined Dewey’s (...) writings for insights on how pragmatist philosophy intersects with the rhetorical tradition. Now comes Scott Stroud’s John Dewey and the Artful Life. Like Danisch and Crick, Stroud explores the nexus .. (shrink)

For Situationist, theorist and film-maker Guy Debord, the aerial view reproduced the falsely objective world-view he called ‘the spectacle’. To counter its myth of an infinitely expandable, omniscient perspective, Debord focused on reducing views from above to ‘derisory documents’ of the social and the environmental through détournement in the two films he made while the Situationist International was in existence. The films engage critically with aerial photography as a hegemonic mode of indexical media, with the aerial view’s application as information (...) image and ornament, and with the formal phenomenon of ciné-mapping. This analysis suggests that the détournement Debord performs in and across these films can be best conceptualized as a critical optic that constitutes a practice of seeing, a mode of reception and a call to action in the social space beyond its aesthetic employ. As such, the optic of détournement is the contestational counterpart to the optic of the aerial view. This remains the case despite the contemporary complexity of photographic views from above and their increased abstraction of social agents and spaces. An alternative to the testimonial function of embodied photographic views, détournement as optic represents an indexical civil contract founded upon representational inadequacy. (shrink)

The overarching theme of Michael Kochin's Five Chapters on Rhetoric seems to be that classical rhetoric is still important. With the help of Socrates, Plato, Aristotle, Gorgias, Callicles, Protagoras, Isocrates, Cicero, Quintilian, and others, Kochin makes the case that when thinking about rhetoric, we ought to listen to the ancients—at least most of the time. While the overarching theme deals with the classical tradition, the book's central argument is focused squarely on current rhetorical practices. The proper role of rhetoric, Kochin (...) argues, is to allow "the facts" to "speak for themselves" (164). He attempts to establish this claim by exploring five concepts that are, or ought to be, central to our .. (shrink)

A splitting of an r.e. set A is a pair A1, A2 of disjoint r.e. sets such that A1 A2 = A. Theorems about splittings have played an important role in recursion theory. One of the main reasons for this is that a splitting of A is a decomposition of A in both the lattice, , of recursively enumerable sets and in the uppersemilattice, R, of recursively enumerable degrees . Thus splitting theor ems have been used to obtain results about (...) the structure of , the structure of R, and the relationship between the two structures. Furthermore it is fair to say that questions about splittings have often generated important new technical developments in recursion theory. In this article we survey most of the results and techniques associated with splitting properties of r.e. sets in ordinary recursion theory. (shrink)

A splitting A1A2 = A of an r.e. set A is called a Friedberg splitting if for any r.e. set W with W — A not r.e., W — Ai≠0 for I = 1,2. In an earlier paper, the authors investigated Friedberg splittings of maximal sets and showed that they formed an orbit with very interesting degree-theoretical properties. In the present paper we continue our investigations, this time analyzing Friedberg splittings and in particular their orbits and degrees for various classes (...) of r.e. sets. (shrink)

A long-standing theme in discussion of perception and thought has been that our primary cognitive contact with individual objects and events in the world derives from our perceptual contact with them. When I look at a duck in front of me, I am not merely presented with the fact that there is at least one duck in the area, rather I seem to be presented withthisthing (as one might put it from my perspective) in front of me, which looks to (...) me to be a duck. Furthermore, such a perception would seem to put me in a position not merely to make the existential judgment that there is some duck or other present, but rather to make a singular, demonstrative judgment, that that is a duck. My grounds for an existential judgment in this case derives from my apprehension of the demonstrative thought and not vice versa. (shrink)

A paradigm of scientific discovery is defined within a first-order logical framework. It is shown that within this paradigm there exists a formal scientist that is Turing computable and universal in the sense that it solves every problem that any scientist can solve. It is also shown that universal scientists exist for no regular logics that extend first-order logic and satisfy the Löwenheim-Skolem condition.

This book defends antitheodicism, arguing that theodicies, seeking to excuse God for evil and suffering in the world, fail to ethically acknowledge the victims of suffering. The authors argue for this view using literary and philosophical resources, commencing with Immanuel Kant's 1791 "Theodicy Essay" and its reading of the Book of Job. Three important twentieth century antitheodicist positions are explored, including "Jewish" post-Holocaust ethical antitheodicism, Wittgensteinian antitheodicism exemplified by D.Z. Phillips and pragmatist antitheodicism defended by William James. The authors argue (...) that these approaches to evil and suffering are fundamentally Kantian. Literary works such as Franz Kafka'sThe Trial, Samuel Beckett's Waiting for Godot, and George Orwell's Nineteen Eighty-Four, are examined in order to crucially advance the philosophical case for antitheodicism.

Temporal Logic: From Ancient Ideas to Artificial Intelligence deals with the history of temporal logic as well as the crucial systematic questions within the field. The book studies the rich contributions from ancient and medieval philosophy up to the downfall of temporal logic in the Renaissance. The modern rediscovery of the subject, which is especially due to the work of A. N. Prior, is described, leading into a thorough discussion of the use of temporal logic in computer science and the (...) understanding of natural language. Temporal Logic: From Ancient Ideas to Artificial Intelligence thus interweaves linguistic, philosophical and computational aspects into an informative and inspiring whole. (shrink)

We examine the prospects for finding “best possible” or “ideal” computing machines for various learning tasks. For this purpose, several precise senses of “ideal machine” are considered within the context of formal learning theory. Generally negative results are provided concerning the existence of ideal learning‐machines in the senses considered.

In his last book, David Armstrong sets out his metaphysical system in a set of concise and lively chapters each dealing with one aspect of the world. He begins with the assumption that all that exists is the physical world of space-time. On this foundation he constructs a coherent metaphysical scheme that gives plausible answers to many of the great problems of metaphysics. He gives accounts of properties, relations, and particulars; laws of nature; modality; abstract objects such as numbers; and (...) time and mind. (shrink)

Is consciousness a purely physical phenomenon? Most contemporary philosophers and theorists hold that it is, and take this to be supported by modern science. But a significant minority endorse non-physicalist theories such as dualism, idealism and panpsychism, among other reasons because it may seem impossible to fully explain consciousness, or capture what it's like to be in conscious states (such as seeing red, or being in pain), in physical terms. This Element will introduce the main non-physicalist theories of consciousness and (...) explain the most important arguments for them, and consider how they each respond to the scientific and other arguments in support of physicalism.

Western democracy is now at a critical juncture. Some worry that power has been wrested from the people and placed in the hands of a small political elite. Others argue that the democratic system gives too much power to a populace that is largely ill-informed and easily swayed by demagogues. This classic study of democratic principles is thus now more relevant than ever. A renowned historian of antiquity and political philosophy, Sir M.I. Finley offers a comparative analysis of Greek and (...) modern conceptions of democracy. As he puts the ancient Greeks in dialogue with their contemporary counterparts, Finley tackles some of the most pressing issues of our day, including public apathy, partisanship, consensus politics, distrust of professional politicians, and the limits of free speech. Including three lectures that Finley delivered at Rutgers University, plus two additional essays that further illuminate his thinking, _Democracy Ancient and Modern _explores the dramatic differences between the close-knit civil society of the ancient Greeks and our own atomized mass societies. By mapping out democracy’s past and its present manifestations, this book helps us plot a course for democracy’s future. (shrink)

The ideal introduction for students of semantics, Lexical Meaning fills the gap left by more general semantics textbooks, providing the teacher and the student with insights into word meaning beyond the traditional overviews of lexical relations. The book explores the relationship between word meanings and syntax and semantics more generally. It provides a balanced overview of the main theoretical approaches, along with a lucid explanation of their relative strengths and weaknesses. After covering the main topics in lexical meaning, such as (...) polysemy and sense relations, the textbook surveys the types of meanings represented by different word classes. It explains abstract concepts in clear language, using a wide range of examples, and includes linguistic puzzles in each chapter to encourage the student to practise using the concepts. 'Adopt-a-Word' exercises give students the chance to research a particular word, building a portfolio of specialist work on a single word. (shrink)

The concept of the receptive field, first articulated by Hartline, is central to visual neuroscience. The receptive field of a neuron encompasses the spatial and temporal properties of stimuli that activate the neuron, and, as Hubel and Wiesel conceived of it, a neuron’s receptive field is static. This makes it possible to build models of neural circuits and to build up more complex receptive fields out of simpler ones. Recent work in visual neurophysiology is providing evidence that the classical receptive (...) field is an inaccurate picture. The receptive field seems to be a dynamic feature of the neuron. In particular, the receptive field of neurons in V1 seems to be dependent on the properties of the stimulus. In this paper, we review the history of the concept of the receptive field and the problematic data. We then consider a number of possible theoretical responses to these data. (shrink)

The phenomenal powers view claims that phenomenal properties metaphysically necessitate their effects in virtue of how they feel, and thereby constitute non-Humean causal powers. For example, pain necessitates that subjects who experience it try to avoid it in virtue of feeling bad. I argue for this view based on the inconceivability of certain phenomenal properties necessitating different effects than their actual ones, their ability to predict their effects without induction, and their ability to explain their effects without appeal to laws (...) or regularities. I also offer a harmony argument according to which the view offers the best explanation for otherwise seemingly fortunate psychophysical regularities. I then outline the view’s main implications for the metaphysics of causation and philosophy of mind. (shrink)

This book presents a collection of essays on institutional theory written by the German sociologist and Weber-expert M. Rainer Lepsius. Based on Weber's work, the author develops concepts of institutional theory, which he subsequently applies to topics such as National Socialism, democratization processes, German unification, and the institutionalization of the European Union. By showing how charismatic leadership can under certain circumstances threaten democratic structures and curtail individual freedoms, and by analyzing the structural and cultural conditions under which people develop trust (...) in political and social structures and ultimately come to support and comply with them, the author provides a sound analytical understanding of the development of democratic institutions and a democratic political culture. This collection of essays was edited, translated and commented on by Claus Wendt. (shrink)
