A questionnaire on business ethics was administered to business professionals and to upper-class business ethics students. On eight of the seventeen situations involving ethical dilemmas in business, students were significantly more willing to engage in questionable behavior than were their professional counterparts. Apparently, many students were willing to do whatever was necessary to further their own interests, with little or no regard for fundamental moral principles. Many students and professionals functioned within Lawrence Kohlberg's stage four of moral reasoning, the law (...) and order stage. Individualism and egoism remain strong patterns in the moral reasoning of many professionals, but they influence moral reasoning patterns among students to a much greater degree. (shrink)

Dickens’s relationship with the Arts has confounded or silenced some of the most eminent critics from his day to ours. His own reticence on the topic likewise makes the idea of a book on Dickens and the Arts a little odd or dissonant. Though as this volume makes clear, he was well versed in a range of high and low arts, he was seemingly determined to embrace, if not the wrong side of the cultural track, metaphorically speaking, a different track. (...) The Introduction is structured around four broad areas which are key to an understanding of both the ideological underpinnings of shifting definitions of the Arts, and to an understanding of the reasons for Dickens’s complex relationship to the idea of the Arts: money/materialism; hierarchies of privilege; yardsticks of criticism or artistic judgement; the public good. There is an uneasy relationship between ‘the Arts’ and all four areas, between Dickens and all four, and between Dickens and the Arts understood via these frames, which are commonly invoked in discussions of the Arts. The contention of this volume is that, far from being a philistine who had no interest in the Arts, Dickens’s apparent reticence in an industrial age where the value and function of the Arts was uniquely important in public debate, masks a complex and sophisticated vision (if not theory) of the Arts in the modern era, which is, and was, ahead of its time. Dickens’s philosophy of art in fact works to complicate in subtle ways the idea of an opposition between idealist and integrationist views of the aesthetic, though its most characteristic thrust is integrationist.

F.A. Hayek studied at the University of Vienna, where he became both a Doctor of Law and a Doctor of Political Science. After several years in the Austrian civil service, he was made the first diector of the Austrian Institute for Business Cycle Research. In 1931 he was appointed Tooke Professor of Economics and Statistics at the London School of Economics, and in 1950 he went to the University of Chicago as Professor of Social and Moral Sciences. He returned to (...) Europe in 1962, to the chair of Economics at the University of Freiburg, where he became Professor Emeritus in 1967. The holder of numerous honorary doctorates, and a member of the British Academy, Hayek was awarded the Nobel Memorial Prize in Economics in 1974. He was created Companion of Honour in 1984. He is the author of some fifteen books, including _Prices and Production, The Pure Theory of Capital, The Road to Serfdom, The Counter-Revolution of Science, The Sensory Order, The Constitution of Liberty, _ _Law, Legislation and Liberty_, and _The Fatal Conceit_.

The current paper proposes the Dysexecutive Luck hypothesis; that beliefs in being unlucky are associated with deficits in executive functioning. Four studies suggest initial support for the Dysexecutive Luck hypothesis via four aspects of executive functioning. Study 1 established that self-reports of dysexecutive symptoms predicted unique variance in beliefs in being unlucky after controlling for a number of other variables previously reported to be related to beliefs around luck. Studies 2 to 4 demonstrated support for the Dysexecutive Luck hypothesis via (...) assessment of executive functioning via: two fundamental executive functions , emotional processes related to executive functioning as described by the Somatic Marker hypothesis, and higher executive functions as accessed via divergent thinking. The findings suggest that individuals’ beliefs in being unlucky are accompanied by a range of deficits in executive functioning. (shrink)

Preparing the Next Generation of Oral Historians is an invaluable resource to educators seeking to bring history alive for students at all levels. Filled with insightful reflections on teaching oral history, it offers practical suggestions for educators seeking to create curricula, engage students, gather community support, and meet educational standards. By the close of the book, readers will be able to successfully incorporate oral history projects in their own classrooms.

Hayek's reputation has gone through a remarkable cycle. An eminent exponent of the Austrian theory of business cycles in the 1930s, he was worsted in the controversy over Keynes' _Treatise on Money_. Following this defeat, Hayek retreated into capital theory, an esoteric branch of economics in which few economists then took an active interest. He gave up economics altogether after the war and turned to psychology, political philosophy, philosophy of law and the history of ideas. However, in 1974 he won (...) the Nobel Prize and returned to mainstream economics as a leading critic of Keynesianism and an advocate of free banking as the answer to inflation. Today Hayek reigns supreme as the kind of moral philosopher and political economist that economics has not seen since Adam Smith. Also forthcoming in this series is _Paul A. Samuelson, 2nd Series_.

Few outstanding questions in the human behavioral sciences are timelier or more urgently debated than the evolutionary source of religious behaviors and beliefs. Byproduct theorists locate the origins of religion in evolved cognitive defaults and transmission biases. Others have argued that cultural evolutionary processes integrated non-adaptive cognitive byproducts into coherent networks of supernatural beliefs and ritual that encouraged in-group cooperativeness, while adaptationist models assert that the cognitive and behavioral foundations of religion have been selected for at more basic levels. Here, (...) we survey these differing approaches, noting their respective strengths and weaknesses. We then advance a novel model that centers on the ability of language to generate alternative worlds independent of immediate empirical facts, and thus highlight the similarities between religious belief and the modes of cognition that underlie institutions in general. The institutional cognition model of religion accounts for some of the shortcomings of extant approaches and draws attention to the human ability to create non-empirical worlds; that is, worlds that are imaginary. Both religious beliefs and institutional facts—such as jurisdictional borders—are non-empirical assertions, yet they are socially accepted as truths and reified through ritual and behavior. One type of non-empirical, linguistically generated belief—supernatural agent belief—is particularly effective for stabilizing systems of arbitrary norms by rooting them in deontic rather than utilitarian reasoning. The evolutionary roots and continued persistence of religion are thus functions of the capacity for humans to generate cognitive alternatives to empirical reality, and the need to stably coordinate those alternative conceptions.

Sir John Hicks is one of the highest-regarded contemporary economists, and it is fitting that the new series of _Critical Assessments of Contemporary Economists_ should commence with his work. Awarded the Nobel Prize for Economics in 1972, Sir John Hicks’ work is extremely wide-ranging, with the list of topics reading almost like an agenda for the whole of modern economics: general equilibrium theory, welfare economics, problems of index numbers, trade cycles, wages and many others. He may, however, be (...) best known to present day economists for having introduced IS-LM curves, now a standard means of Keynesian analysis. A comprehensive, scholarly work, this four-volume set gives students of economics and economic thought immediate access to Sir John Hicks' contributions and shows how his work has been received and modified by others.

This new Major Work from Routledge is a five-volume collection of the key critical assessments of Amartya Sen, probably best known for his work on famine, human development and welfare economics. Sen is one of the few modern academics who has commanded much respect and recognition from across the intellectual spectrum. His work—for which he was awarded the Nobel Prize in 1998—simultaneously embraces social choice theory and economic development, thus breaking the barrier between mathematized ‘high theory’ and ‘real world’ economics. (...) With an introduction newly written by the editor that places the collected work in its intellectual and historical context, this collection is destined to be welcomed as an invaluable resource for both reference purposes and as a contribution to the study of Amartya Sen.

This volume explores how Catholicism began and continues to open its doors to the wider world and to other confessions in embracing ecumenism, thanks to the vision and legacy of the Second Vatican Council. It explores such themes as the twentieth century context preceding the council; parallels between Vatican II and previous councils; its distinctively pastoral character; the legacy of the council in relation to issues such as church-world dynamics, as well as to ethics, social justice, economic activity. Several chapters (...) discuss the role of women in the church before, during, and since the council. Others discern inculturation in relation to Vatican II. The book also contains a wide and original range of ecumenical considerations of the council, including by and in relation to Free Church, Reformed, Orthodox, and Anglican perspectives. Finally, it considers the Council’s ongoing promise and remaining challenges with regard to ecumenical issues, including a groundbreaking essay on the future of ecumenical dialogue by Cardinal Walter Kasper.

Estimates of unknown quantities are influenced by both self-generated anchors (SGAs) and externally provided anchors (EPAs; e.g., the advice of others). It was hypothesised that people use the degree of similarity between these anchors to render final responses. Thus we tested predictions drawn from metacognitive accounts of anchoring using procedures similar to the traditional anchoring paradigm. In a single experiment we manipulated SGA–EPA similarity, EPA level, and EPA source credibility. Results showed that the relationship between SGA–EPA similarity and the decision (...) weight given to the EPA, relative to the weight given to the SGA, depended on source credibility. Bolstering the metacognitive framework, participants were most confident about their final responses when their SGA was similar to the EPA and the EPA came from a highly credible source. These results support a metacognitive account of the anchoring heuristic. (shrink)

Sir John Hicks is one of the most important and influential economists of the twentieth century. Awarded the Nobel Prize for economics in 1972, he has made contributions across a wide range of economic theory, writing some twenty books. Arguably the most important of these, _Value and Capital_, is seen as the roots of modern microeconomics and general equilibrium theory. Hicks possessed an unusual ability to synthesize the ideas of other economists – something that is evident in his invention (...) of the ‘IS-LM’ diagram to expound Keynes’ General Theory, and is perhaps what he is best known to present day economists for. This two volume set is the second collection on Hicks in this series and includes new assessments of his contributions, covering the last fifteen years. With a new introduction by the editor, this comprehensive and scholarly collection provides students and scholars immediate access to Sir John Hicks’ contributions. (shrink)

John Woods' The Logic of Fiction, now thirty-five years old, is a ground-breaking event in the establishment of the semantics of fiction as a stand-alone research programme in the philosophies of language and logic. There is now a large literature about these matters, but Woods' book retains a striking freshness, and still serves as a convincing template of the treatment options for the field's key problems. The book now appears in a second edition with a new Foreword by Nicholas (...) Griffin and an extended bibliography covering the period 1969-2009. As Griffin notes in his Foreword, it is "surprising on looking back to discover how little was written on the semantics of fiction before John Woods' The Logic of Fiction was published in 1974. The surprise is the greater because Woods' book appeared after almost a quarter century of fierce philosophical debate about reference Fictional discourse, one would have thought, would be an important testing ground for philosophical theories of referential expressions and one, moreover, in which the standard theories would likely be tested to destruction. " " One of the great merits of Woods' book is that it takes seriously the wide-ranging demands that fiction imposes on logic and semantics, and does not try to force fiction into some pre-conceived logical mould. but thanks to Woods' pioneering efforts, we are much closer to one now than we were when he set out to write his book. His book was not the last word on the logic of fiction; it was much more important: it was nearly the first." NICHOLAS GRIFFIN is Canada Research Chair in Philosophy at McMaster University. Recent publications include Russell vs Meinong: The Legacy of "On Denoting," edited with Dale Jacquette. JOHN WOODS is Director of the Abductive Systems Group at the University of British Columbia and Charles S. Peirce Visiting Professor of Logic in the Group on Logic and Computational Science, King's College London. He has two forthcoming books on fiction - an edited volume, Fictions and Models: New Essays, and a research monograph, Sherlock's Member: New Perspectives on the Semantics of Fiction, both to appear in 2010.

As John Henry Newman reflected on 'The Idea of a University' more than a century and a half ago, Bradley C. S. Watson brings together some of the nation's most eminent thinkers on higher education to reflect on the nature and purposes of the American university today.

Historically, the fallacies have been neglected as objects of systematic study. Yet, since Hamblin's famous criticism of the state of fallacy theory, a substantial literature has been produced. A large portion of this literature is the work of Douglas Walton and John Woods. This paper will deal directly with the criticism of that work which has been advanced by van Eemeren and Grootendorst, particularly the complaints found in their writings of 1992, concerning the disunification of the fallacies and the (...) exemplaristic approach of Woods and Walton's theories. It proposes a unification of the theories of Woods and Walton with that of van Eemeren and Grootendorst, and suggests that such a unification could be advantageous to both theories, and highly interesting for fallacy theory in general.

Perelman and Olbrechts-Tyteca write in The New Rhetoric that, “The first half of this chapter is devoted to the analysis of the relations that establish reality by resort to the particular case. The latter can play a wide variety of roles; as an example, it makes generalization possible....” I will suggest that no fallacy theorist or philosopher of science who has a serious interest in bringing the fallacy of hasty generalization to theoretical heel should omit consideration of these wise Belgian (...) words. Although these very words appear to endorse the fallacy outright, they do no such thing in fact. It proves instructive to learn why. (shrink)

Below are reflections on Peirce’s conception of abductive methods and Russell’s conception of regressive methods. Along the way, it will be necessary to examine the marked differences between Russell and Frege on the ins and outs of logicism, from which latter the regressivist ideas first emerged. Russell was aware of Peirce’s contributions to the algebraization of logic and Peirce was aware of Russell’s writings on logicism. However, in framing his thoughts about regressive methods, Russell showed no familiarity with Peirce’s treatment (...) of abductive methods. In 1907, Russell read to the Cambridge Mathematics Club an essay entitled “The regressive method of discovering the premises of mathematics.” Since that paper didn’t see the published light of day until three years after Russell’s death in 1970, Peirce couldn’t have taken notice of it in developing his ideas about abduction. Even so, it has been suggested that there exists a noteworthy similarity between Russell’s regressivism and Peirce’s abductivism. The principal purpose of this essay is to show the resemblance to have been misjudged, in which case, my title would have to be corrected. (shrink)

In Abortion and Moral Theory, L. W. Sumner develops a moderate view of abortion, having dispatched as “indefensible” “two equally prominent and extreme positions: the liberal view … and the conservative view”. It is a distinctive feature of the book that, having formulated what he regards as the correct intuitive position, the author seeks for it “the needed foundation for a moderate view of abortion”, since “the defense of a moderate position must ultimately be grounded in moral theory”, in which (...) the position acquires “theoretical depth”, and without which it would lack “philosophical justification”. The moral theory in which Professor Sumner seeks to lodge his moderate position is the “classical version of utilitarianism”, which “can serve as the deep structure of a moderate view of abortion”. Thus, a central task for the appraisal of Abortion and Moral Theory is to ascertain whether classical utilitarianism can be made to accommodate “common-sense morality [which] plainly regards murder as wrong principally because of its central effects …”, that is, because murder causes “its victim some form of harm”.

Consider the proposition, "Informal logic is a subdiscipline of philosophy". The best chance of showing this to be true is showing that informal logic is part of logic, which in turn is a part of philosophy. Part 1 is given over to the task of sorting out these connections. If successful, informal logic can indeed be seen as part of philosophy; but there is no question of an exclusive relationship. Part 2 is a critical appraisal of the suggestion that informal (...) logic is applied epistemology. Part 3 examines the claim that informal logic has failed to penetrate into mainstream philosophy, and suggestions for amelioration are considered. (shrink)

An agent-centered, goal-directed, resource-bound logic of human reasoning would do well to note that individual cognitive agency is typified by the comparative scantness of available cognitive resources—information, time, and computational capacity, to name just three. This motivates individual agents to set their cognitive agendas proportionately, that is, in ways that carry some prospect of success with the resources on which they are able to draw. It also puts a premium on cognitive strategies which make economical use of those resources. These (...) latter I callscant-resource adjustment strategies,and they supply the context for an analysis of abduction. The analysis is Peircian in tone, especially in the emphasis it places on abduction’signorance-preservingcharacter. My principal purpose here is to tie abduction’s scarce-resource adjustment capacity to its ignorance preservation. (shrink)

In a world plagued by disagreement and conflict one might expect that the exact sciences of logic and mathematics would provide a safe harbor. In fact these disciplines are rife with internal divisions between different, often incompatible, systems. Do these disagreements admit of resolution? Can such resolution be achieved without disturbing assumptions that the theorems of logic and mathematics state objective truths about the real world? In this original and historically rich book John Woods explores apparently intractable disagreements in (...) logic and the foundations of mathematics and sets out conflict resolution strategies that evade or disarm these stalemates. An important sub-theme of the book is the extent to which pluralism in logic and the philosophy of mathematics undermines realist assumptions. This book makes an important contribution to such areas of philosophy as logic, philosophy of language and argumentation theory. It will also be of interest to mathematicians and computer scientists.

A common reaction among idealist philosophers to the classical syntactic characterization of proof so crisply articulated by Tarski is an urgent but inchoate Angst that something momentous is missing, an awesome intimation of bereftness. The simple fact is that in many pursuits proof involves an empirical appeal, an operation that Tarski excludes from the domain of proof and assigns to the company of confirmation. In Tarski’s terms, empirical statements never even admit of the predicate true, let alone proved, unless perhaps (...) they hanker after truth or proof in the limit in some dimly understood and always unsuccessful way. Some sources of queasiness about the syntactic account are not hard to pinpoint. On the syntactic account, the injunction “Prove it!” can never be fulfilled, or even well-formedly uttered, in regard to an empirical statement, ┏∅, therefore ∅┓ is valid for any well-formed ∅ in a given first-order language, for any theorem, t, ┏∅, therefore t┓ is an impeccable proof for any well-formed ∅ in the classical languages. It is easy to think, with Bradley, that there is an important and legitimate, if not formally well-articulated sense of proof, characteristic of much of philosophical reasoning and argumentation, which is badly misrepresented by the syntactic conception. The kind of proof often sought after in theology, and sought after and found in the law, and the experimental and social sciences, is not purely syntactic. Idealists, of course, have frequently expressed dissatisfaction with the Tarski conception of truth. We will here extend this skepticism to the Tarski notion of proof. (shrink)

The God of the Biblical and patristic tradition, though perhaps incomplete, possesses properties including those that involve genidentity or C-connections with us. Thus God's existence is at least possible. Using a modified version of Parson's elaboration of Meinong's theory of objects, we find that God exists if we do. But we also find that much else exists if we do; rather too much for confident belief.

The totality of evidence heard in a trial is usually collectively inconsistent, indeed often jointly incoherent. In those cases in which each party offers its own theory of the evidence, an abduction is forwarded which best explains a coherent subset of the evidence. Since these are themselves often jointly incoherent subsets S and S*, we have the following difficulty. Opposing theories are those which purport best to explain different sets of the evidence. In that sense, they aren’t rival theories. How (...) could they be, since “E best explains S” and “~E best explains S*” could both be true? How can the defence’s theory of the case answer the prosecution’s if it does not in some sense contradict it? Examination of the empirical record suggests that when faced with this kind of incommensurability, jurors form their own evidential subsets, for which they themselves try to furnish seek for the best explanation. This at once raises a difficult question. On what basis does a juror select the evidence which his eventual abduction will best explain? It is well-understood that opposing counsel select their respective evidence-sets tendentiously, with a view to facilitation of the desired abduction. But jurors are sworn to objectivity and impartiality. How, or whether, jurors manage to fulfill this obligation is the subject of this paper. A solution will be proposed that draws on Simulation Theory, which arises from recent psychological research. (shrink)

There are passages in Fallacies suggesting a skeptical attitude to the very idea of inductive arguments, hence to the existence of inductive fallacies. Although the passages are brief and few in number, it would appear that Hamblin’s resistance stems from doubts about the existence of relations of inductive consequence.

Its greater importance lies in the (...) threat it creates for the whole class of nonmonotonic logics. (shrink)

In all three of its manifestations, —abusive, circumstantial and tu quoque—the role of the ad hominem is to raise a doubt about the opposite party’s casemaking bona-fides.Provided that it is both presumptive and provisional, drawing such a conclusion is not a logical mistake, hence not a fallacy on the traditional conception of it. More remarkable is the role of the ad hominem retort in seeking the reassurance of one’s opponent when, on the face of it, reassurance is precisely what he (...) would seem to be ill-placed to give. Brief concluding remarks are given over to an examination of rival approaches to the ad hominem, especially those in which it is conceived of as a dialectical error. (shrink)

True to the spirit of Topoi’s Untimely Reviews section, the present essay is a work of the counterfactual imagination.

What, in those circumstances, would philosophical commentary look like, especially against the marked developments in Quine’s philosophy in that same period?

It is one thing for a given proposition to follow or to not follow from a given set of propositions and it is quite another thing for it to be shown either that the given proposition follows or that it does not follow.* Using a formal deduction to show that a conclusion follows and using a countermodel to show that a conclusion does not follow are both traditional practices recognized by Aristotle and used down through the history of logic. These (...) practices presuppose, respectively, a criterion of validity and a criterion of invalidity each of which has been extended and refined by modern logicians: deductions are studied in formal syntax (proof theory) and coun¬termodels are studied in formal semantics (model theory). The purpose of this paper is to compare these two criteria to the corresponding criteria employed in Boole’s first logical work, The Mathematical Analysis of Logic (1847). In particular, this paper presents a detailed study of the relevant metalogical passages and an analysis of Boole’s symbolic derivations. It is well known, of course, that Boole’s logical analysis of compound terms (involving ‘not’, ‘and’, ‘or’, ‘except’, etc.) contributed to the enlargement of the class of propositions and arguments formally treatable in logic. The present study shows, in addition, that Boole made significant contributions to the study of deduc¬tive reasoning. He identified the role of logical axioms (as opposed to inference rules) in formal deductions, he conceived of the idea of an axiomatic deductive sys¬tem (which yields logical truths by itself and which yields consequences when ap¬plied to arbitrary premises). Nevertheless, surprisingly, Boole’s attempt to imple¬ment his idea of an axiomatic deductive system involved striking omissions: Boole does not use his own formal deductions to establish validity. Boole does give symbolic derivations, several of which are vitiated by “Boole’s Solutions Fallacy”: the fallacy of supposing that a solution to an equation is necessarily a logical consequence of the equation. This fallacy seems to have led Boole to confuse equational calculi (i.e., methods for gen-erating solutions) with deduction procedures (i.e., methods for generating consequences). The methodological confusion is closely related to the fact, shown in detail below, that Boole had adopted an unsound criterion of validity. It is also shown that Boole totally ignored the countermodel criterion of invalid¬ity. Careful examination of the text does not reveal with certainty a test for invalidity which was adopted by Boole. However, we have isolated a test that he seems to use in this way and we show that this test is ineffectual in the sense that it does not serve to identify invalid arguments. We go beyond the simple goal stated above. Besides comparing Boole’s earliest criteria of validity and invalidity with those traditionally (and still generally) employed, this paper also investigates the framework and details of THE MATHEMATICAL ANALYSIS OF LOGIC.

Epistemology and informal logic have overlapping and broadly similar subject matters. A principle of methodological symmetry is: philosophical theories of sufficiently similar subject matters should engage similar methods. Suppose the best way to do epistemology is in highly formalized ways, with a large role for mathematical methods. The symmetry principle suggests this is also the best way to do the logic of the reasoning and argument, the subject matter of informal logic. A capitulation to mathematics is inimical to informal logicians, (...) yet formal methods and mathematical models are an emerging force in epistemology. What is to be done? What’s sauce for the goose of epistemology is sauce for the gander of informal logic. (shrink)

This book's importance is derived from three sources: careful conceptualization of teacher induction from historical, methodological, and international perspectives; systematic reviews of research literature relevant to various aspects of teacher induction including its social, cultural, and political contexts, program components and forms, and the range of its effects; substantial empirical studies on the important issues of teacher induction with different kinds of methodologies that exemplify future directions and approaches to the research in teacher induction.

In their book, Relevance, Sperber and Wilson make an important contribution towards constructing a credible theory of this unforthcoming notion. All is not clear sailing, however. If it is accepted as a condition on the adequacy of any account of relevance that it not be derivable either that nothing is relevant to anything or that everything is relevant to everything, it can be shown that Sperber and Wilson come close to violating the condition.

Needed for such dialogue games as dialectic are appropriate standards of fairness and rationality. The rules of procedure of dialectic must describe a game playable by actual human participants. The present paper centers on certain idealizations of the dialectician that are not allowable.

In criminal cases at common law, juries are permitted to convict on wholly circumstantial evidence even in the face of a reasonable case for acquittal. This generates the highly counterintuitive—if not absurd—consequence that there being reason to think that the accused didn’t do it is not reason to doubt that he did. This is the no-reason-to-doubt problem. It has a technical solution provided that the evidence on which it is reasonable to think that the accused didn’t do it is a (...) different subset of the total evidence from that on which there is no reason to doubt that he did do it. It lies in the adversarial nature of criminal proceedings in the common law tradition that the subsets of the total evidence on which counsel base their opposing arguments are themselves different from and often incompatible with one another. While this solves the no-reason-to-doubt problem, it does so at the cost of triggering a second problem just as bad. It is the no-rival problem, according to which incompatible theories of the case based on incompatible subsets of the evidence cannot be rivals of one another. If neither party’s case contradicts the other’s then, by the burden of proof requirement, criminal convictions are impossible. Once having generated the dilemma, the object of the paper is to determine how it might be escaped. (shrink)

This article describes methods and ideas that emerged from a continuing enquiry into ‘metadesign’ that led us to think about the role of ‘consciousness’ in teams, communities and the biosphere. In the West the notion of ‘consciousness’ has been shaped by humanism, industrialization and some strident forms of individualism. These have encouraged us to see it in strongly anthropocentric and solipsistic terms. The global economic system also reflects this individualistic ideology, given that ‘growth’, is driven by personal avarice on a (...) collective scale. On the other hand, capitalism encourages enterprises to scale-up when they become successful. Both tendencies reduce the consciousness of organizations and communities. The article illustrates this idea by describing a ‘quadratic’ model of team consciousness that was developed to enhance practical developments that support personal, interpersonal, transpersonal and environmentally situated modes of awareness.

In an attempt to overcome the traditional casual neglect of the study of the informal fallacies, we here treat one fallacy, the ad baculum, at an adequate theoretical level in order to determine how it may best be understood as a fallacy.

If one looks to the current textbook lore for reliable taxonomic and analytical information about the petitio principii, one is met with conceptual disarray and much too much nonsense. The present writers have recently attempted to furnish the beginnings of a theoretical reconstruction of this fallacy which is at once faithful to its formidable complexity yet useful as guide for its detection and avoidance. The fact is that the petitio has had a lengthy and interesting history, and in this paper (...) we shall want to explore certain features of its development, such as it may have been. The principal origins of the concept of circular argument are to be found in Aristotle. The Aristotelian doctrine recurs with variations in the sophismata literature of the middle ages and in logic texts and manuals right up to the present day. (shrink)

For scientific essentialists, the only logical possibilities of existence are the real (or metaphysical) ones, and such possibilities, they say, are relative to worlds. They are not a priori, and they cannot just be invented. Rather, they are discoverable only by the a posteriori methods of science. There are, however, many philosophers who think that real possibilities are knowable a priori, or that they can just be invented. Marc Lange [Lange 2004] thinks that they can be invented, and tries to (...) use his inventions to argue that the essentialist theory of counterfactual conditionals developed in Scientific Essentialism [Ellis 2001, hereafter SE ] is flawed.

This monograph examines truth in fiction by applying the techniques of a naturalized logic of human cognitive practices. The author structures his project around two focal questions. What would it take to write a book about truth in literary discourse with reasonable promise of getting it right? What would it take to write a book about truth in fiction as true to the facts of lived literary experience as objectivity allows? It is argued that the most semantically distinctive feature of (...) the sentences of fiction is that they are unambiguously true and false together. It is true that Sherlock Holmes lived at 221B Baker Street and also concurrently false that he did. A second distinctive feature of fiction is that the reader at large knows of this inconsistency and isn't in the least cognitively molested by it. Why, it is asked, would this be so? What would explain it? Two answers are developed. According to the no-contradiction thesis, the semantically tangled sentences of fiction are indeed logically inconsistent but not logically contradictory. According to the no-bother thesis, if the inconsistencies of fiction were contradictory, a properly contrived logic for the rational management of inconsistency would explain why readers at large are not thrown off cognitive stride by their embrace of those contradictions. As developed here, the account of fiction suggests the presence of an underlying three - or four-valued dialethic logic. The author shows this to be a mistaken impression. There are only two truth-values in his logic of fiction. The naturalized logic of Truth in Fiction jettisons some of the standard assumptions and analytical tools of contemporary philosophy, chiefly because the neurotypical linguistic and cognitive behaviour of humanity at large is at variance with them. Using the resources of a causal response epistemology in tandem with the naturalized logic, the theory produced here is data-driven, empirically sensitive, and open to a circumspect collaboration with the empirical sciences of language and cognition.
