This paper synthesizes convergent lines of evidence to evaluate the hypothesis that objective falsity is essential to lying. Objective accounts of lying affirm this hypothesis; subjective accounts deny it. Evidence from history, logic, social observation, popular culture, lexicography, developmental psychology, inference, spontaneous description, and behavioral experimentation strongly supports the hypothesis. Studies show that the only apparent evidence against the hypothesis is due to task substitution, i.e. ethical concerns or perspective-taking interfering with performance on categorization tasks. I conclude that, overall, (...) existing evidence decisively favors objective accounts. (shrink)

Ronald Dworkin’s argument from theoretical disagreement remains a pressing challenge for legal positivists. In this paper, I show how positivists can answer Dworkin’s argument without having to attribute confusion or disingenuity to legal officials. I propose that the argument rests on two errors. The first is to assume that positivism requires legal officials to converge on precise grounds of law when convergence on more general grounds will do. The second is to construe judicial speech too (...) literally. If we pay attention to the pragmatics of judicial speech, we see that judges do not disagree over what the grounds of law are; they at most disagree over how courts should proceed when agreed-upon, though imprecise, grounds of law underdetermine what the content of the law directs in the case at hand.

Ronald Dworkin argues that disagreement in hard cases is ‘theoretical’ rather than empirical and of central importance to our understanding of law, showing ‘plain fact’ theories such as H. L. A. Hart’s sophisticated legal positivism to be false. The argument from theoretical disagreement targets positivism’s commitment to idea that the criteria a norm must meet to be valid in a given jurisdiction are constituted by a practice of convergent behavior by legal officials. The ATD suggests that in hard (...) cases there is no such pattern of convergent behavior. Positivists are divided over the force of the ATD. Much of this disagreement over the force of the ATD can be understood as disagreement over just what it is that legal officials disagreeing ‘theoretically’ are disagreeing about. Once the scope of empirical and theoretical disagreements are more accurately plotted, we will see that the actual disagreements that occur in hard cases are not ones which threaten a deeper and pervasive pattern of convergent behavior, one which focuses not upon rules specifying criteria of legal validity, but instead upon broad processes for making, interpreting, and applying law. Such an account remains positivist, relying on the social fact that there is such a consensus, but allows for considerable disagreement among legal officials deciding cases within such procedures.

Although science and law employ different methods to gather and weigh evidence, their conclusions are remarkably convergent with regard to the effect that workplace stress has on the health of employees. Science, using the language of probability, affirms that certain stressors predict adverse health outcomes such as disabling anxiety and depression, cardiovascular disease, certain types of injury, and a variety of immune system disorders. Law, using the language of reasonable foreseeability, affirms that these adverse outcomes are predictable under certain conditions, (...) typically defined in relation to what a reasonable person should know. Society is arguably in a position to establish standards for the abatement of certain types of workplace stress. As part of this process, we need to conceptualize an ideal form of conduct that exemplifies the standards to which both law and science urge us to aspire. For this purpose, the concept of the neighbor at work is proposed. (shrink)

Many in the informal logic tradition distinguish convergent from linked argument structure. The pragma-dialectical tradition distinguishes multiple from co-ordinatively compound argumentation. Although these two distinctions may appear to coincide, constituting only a terminological difference, we argue that they are distinct, indeed expressing different disciplinary perspectives on argumentation. From a logical point of view, where the primary evaluative issue concerns sufficient strength of support, the unit of analysis is the individual argument, the particular premises put forward (...) to support a given conclusion. Structure is internal to this unit. From a dialectical point of view, where the focus concerns how well a critical discussion comes to a reasoned conclusion of some disputed question, the argumentation need not constitute a single unit of argument. The unit of dialectical analysis will be the entire argumentation made up of these several arguments. The multiple/co-ordinatively compound distinction is dialectical, while the linked/convergent distinction is logical. Keeping these two pairs of distinctions separate allows us to see certain attempts to characterize convergent versus linked arguments as rather characterizing multiple versus co-ordinatively compound arguments, in particular attempts of Thomas, Nolt, and Yanal, and to resolve straightforwardly conflicts, tensions, or anomalies in their accounts. Walton's preferred Suspension/Insufficient Proof test to identify linked argument structure correctly identifies co-ordinatively compound structure. His objection to using the concept of relevance to explicate the distinction between linked and convergent structure within co-ordinatively compound argumentation can be met through explicating relevance in terms of inference licenses. His counterexample to the Suspension/No Support test for identifying linked structure which this approach supports can itself be straightforwardly dealt with when the test is explicated through inference licenses.

A number of authors have pointed to “convergent evolution” as evidence for the central role of natural selection in shaping predictable trajectories of macroevolution. However, there are numerous conceptual and empirical difficulties that arise in broadly appealing to the frequency of homoplasy as evidence for a non-contingently constrained adaptational design space. Most important is the need to distinguish between convergent (externally constrained) and parallel (internally constrained) evolution, and to consider how the respective frequencies of these significantly different sources of homoplasy (...) affect a strong adaptationist view of life. In this paper, I critically evaluate Simon Conway Morris’s use of the homoplasy literature to support his argument for a non-contingent, counterfactually stable account of macroevolutionary pattern. In so doing, I offer a conception of parallelism which avoids the charge that it differs from convergence merely in degree and not in kind. I argue that although organisms sharing a homoplastic trait will also share varying degrees of homology, it is the underlying developmental homology with respect to the generators directly causally responsible for the homoplastic event that defines parallel evolution and non-arbitrarily distinguishes it from convergence. The notion of “screening-off” is used to distinguish the proximal generators of a homoplastic trait from its more distal genetic causes (such as a master control gene). (shrink)

Bryan Norton 's convergence hypothesis, which predicts that nonanthropocentric and human-based philosophical positions will actually converge on long-sighted, multi-value environmental policy, has drawn a number of criticisms from within environmental philosophy. In particular, nonanthropocentric theorists like J. Baird Callicott and Laura Westra have rejected the accuracy of Norton 's thesis, refusing to believe that his model's contextual appeals to a plurality of human and environmental values will be able adequately to provide for the protection of ecological integrity. These (...) theoretical criticisms of convergence, however, have made no real attempt to engage the empirical validity of the hypothesis, the dimension that Norton clearly takes to be the centerpiece of his project. Accordingly, the present paper attempts to provide an empirical analysis of the convergence argument, by means of a study of the Vermont public's environmental commitments and their attitudes toward national forest policy. Our findings support a generalized version of Norton 's thesis, and lead us to suggest that environmental philosophers should try to be more inclusive and empirically minded in their discussions about public moral claims regarding nature.

Stephen Jay Gould argued that replaying the “tape of life” would result in a radically different evolutionary outcome. Some biologists and philosophers, however, have pointed to convergent evolution as evidence for robust replicability in macroevolution. These authors interpret homoplasy, or the independent origination of similar biological forms, as evidence for the power of natural selection to guide form toward certain morphological attractors, notwithstanding the diversionary tendencies of drift and the constraints of phylogenetic inertia. In this paper, I consider the implications (...) of homoplasy for the debate over the nature of macroevolution. I argue that once the concepts of contingency and convergence are fleshed out, it becomes clear that many instances of homoplasy fail to negate Gould’s overarching thesis, and may in fact support a Gouldian view of life. My argument rests on the distinction between parallelism and convergence, which I defend against a recent challenge from developmental biology. I conclude that despite the difficulties in defining and identifying parallelism, the concept remains useful and relevant to the contingency controversy insofar as it underscores the common developmental origins of iterated evolution.

One popular test for distinguishing linked and convergent argument structures is Robert Yanal's Ordinary Summing Test. Douglas Walton, in his comprehensive survey of possible candidates for the linked/convergent distinction, advocates a particular version of Yanal's test. In a recent article, Alexander Tyaglo proposes to generalize and verifY Yanal's algorithm for convergent arguments, the basis for Yanal's Ordinary Summing Test. In this paper I will argue that Yanal's ordinary summing equation does not demarcate convergence and so his Ordinary Summing (...) Test fails. Hence, despite Walton's recommendation or Tyaglo's generalization, the Ordinary Summing Test should not be used for distinguishing linked argument structures from convergent argument structures.

Structured around Charles S. Peirce's three-fold categorical scheme, this article proposes a comparative study of Ayn Rand and Peirce's realist views in general metaphysics. Rand's stance is seen as diverging with Peirce's argument from asymptotic representation but converging with arguments from brute relation and neutral category. It is argued that, by dismissing traditional subject-object dualisms, Rand and Peirce both propose iconoclastic construals of what it means to be real, dismissals made all the more noteworthy by the fact (...) each chose to ground them in indissoluble triads of self-evident first principles.

Bipolar argument graphs represent the structure of complex pro and contra arguments for one or more standpoints. In this article, ampliative and exclusionary principles of evaluating argument strength in bipolar acyclic argumentation graphs are laid out and compared to each other. Argument chains, linked arguments, link attackers and supporters, and convergent arguments are discussed. The strength of conductive arguments is also addressed but it is argued that more work on this type of argument is needed to (...) properly distinguish argument strength from more general value-based components of such arguments. The overall conclusion of the article is that there is no justifiably unique solution to the problem of argument strength outside of a particular epistemological framework. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Philosophy 38.2 (2000) 221-238 [Access article in PDF] Hume's Iterative Probability Argument: A Pernicious Reductio Kevin Meeker University of South Alabama In this essay I want to look afresh at David Hume's iterative probability argument, found in the section entitled "Of Scepticism with regard to Reason" in his A Treatise of Human Nature.1 Interestingly enough, after years of comparative neglect,2 this (...) class='Hi'>argument has been basking in the glow of scholarly sunshine lately.3 But to what can we attribute its extended hiatus? The convergence of three major factors seems responsible. First, philosophers have oftentimes flung this argument into the ocean of obscurity because of its perceived inadequacies.4 Second, and on a related note, many assume that Hume himself permitted this argument to drown because it never resurfaces again in his writings. Most suspiciously, Hume's Enquiry Concerning Human Understanding, which is his popular (and preferred) presentation of the epistemological sections [End Page 221] of the Treatise, does not contain this argument.5 Last, but certainly not least, for a long time this argument sat uncomfortably with the naturalist interpretation of Hume6 that has gained ascendancy in the twentieth century. For prior to this century, Hume was almost unanimously regarded as a sceptic. Despite a few waves from those who interpreted Hume as a logical positivist earlier in this century, Norman Kemp Smith charted a new course for Humean interpretations with his emphasis on Hume's naturalism.7 And this is the current according to which most Hume interpreters set their sails today.Because the naturalist reading of Hume relies so heavily on the system he attempts to set forth in the Treatise, though, naturalists have come to see the importance of reading this argument in a naturalistically acceptable way. William E. Morris best expresses the significance of this argument from a naturalistic perspective in the following manner: If we ever are to understand Hume's view of the role of reason, it stands to reason that we should first figure out how to integrate "Of scepticism with regard to reason" into the picture. Only then will we be ready to move to a consideration of Hume's positive views about reason. These views are the least understood of any of Hume's doctrines. Gaining an adequate understanding of them is both the most pressing and the most difficult problem facing Hume studies today.8While I agree with Morris about the importance of getting a clear understanding of the reasoning of I, iv, 1, I will argue that a correct reading of this section reveals the implausibility of major naturalistic interpretations of Hume.This paper has four major sections. In the first important section, I will highlight the crucial aspects of the iterative argument that will be the focus of this paper and deal with a preliminary but important interpretive issue. In the second section, I will briefly look at Annette Baier's naturalistic reading of Hume's philosophy to show how this particular passage bears on broader [End Page 222] interpretive issues. The third main section will focus on explicating Morris' similar but more detailed interpretation. Finally in the last part I will show that while it is legitimate to characterize the argument here as a reductio (as Baier and Morris both do), the argument still yields, contrary to what naturalists have recently suggested, a very sceptical conclusion. 1. The Arguments of Section I, IV, 1 of the TreatiseHume's "Of Scepticism with regard to Reason" contains at least two important arguments. While Hume agrees that knowledge involves certainty (whereas beliefs based on probability are by their very nature uncertain9 ), the conclusion of his first argument is that "all knowledge resolves itself into probability" (Treatise, 181). His point here is simply that all of our beliefs are fallible. That is, nothing is absolutely certain; thus none of our beliefs attain the exalted status of certain knowledge. But once this consequence of our fallibility is recognized, he then argues roughly that the probability that any particular belief... (shrink)

Over the course of human history there appears to have been a global shift in moral values towards a broadly ‘liberal’ orientation. Huemer argues that this shift better accords with a realist than an antirealist metaethics: it is best explained by the discovery of mind-independent truths through intuition. In this article I argue, contra Huemer, that the historical data are better explained assuming the truth of moral antirealism. Realism does not fit the data as well as Huemer suggests, whereas antirealists (...) have underappreciated resources to explain the relevant historical dynamics. These resources include an appeal to socialization, to technological and economical convergences, to lessons learned from history, to changes induced by consistency reasoning and to the social function of moral norms in overcoming some of the cooperation problems that globalizing societies face. I point out that the realist’s explanans has multiple shortcomings, that the antirealist’s explanans has several explanatory virtues, and conclude that the latter provides a superior account of the historical shift towards liberal values.

ABSTRACT There is a growing trend in moral philosophy that reflects a return to a more ancient perspective of the subject matter wherein moral theory and moral practice are thought to converge. Like their Greek and Hellenistic predecessors, contemporary moral philosophers are again analysing virtues and character traits, drawing normative conclusions at the end of arguments, and testing their theories against examples from common life. Unfortunately, this literature is still cluttered with abstract, general, unlikely, and cleverly‐constructed examples that are (...) more apt to draw both reader and author away from the various moral issues under consideration. This paper argues that the selection of examples drawn from literature, history and common‐life experiences offers the following advantages: (1) such examples better serve the purpose of illustration; (2) they function as projects for moral inquiry; (3) they better connect both reader and author to the moral issues being discussed; (4) they help prevent the dichotomisation of moral philosophy into meta‐ethics and applied ethics; and (5) they help make it possible again for moral philosophy to have the relevance and importance it once enjoyed in previous periods of history. Selection criteria are outlined, and examples are provided that satisfy them. (shrink)

Historians and philosophers of science have furnished a wide array of theoretical-historiographical terms to emphasize the discontinuities among different systems of knowledge. Some of the most famous include Thomas Kuhn’s “paradigm”, Michel Foucault’s “episteme”, and the notion of “styles of reasoning” more recently developed by Ian Hacking and Arnold Davidson. This paper takes up this theoretical-historiographical thread by assessing the values and limitations of the notion of “style” for the historical and philosophical study of science. Specifically, reflecting on various methodological (...) and theoretical concerns prompted by sexuality, translation, and East Asian studies, this paper argues that the heretofore ways in which historians and philosophers of science have used the notion of “style” are severely restricted in terms of its mere applicability to the intellectual history of Western science. The particular example of the translation of “homosexuality” into Chinese during the May Fourth era reveals that the notion of “style” has the potential of carrying a much more dynamic conceptual weight, as when used in “styles of argumentation”. The paper also engages briefly with the historiography of scientific “national styles” and ends with some concluding remarks on the limitations of “social histories from below” and the under appreciated importance of “epistemological histories of possibilities”.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Converging Ways? Conversion and Belonging in Buddhism and ChrisitanityCatherine CornilleConverging Ways? Conversion and Belonging in Buddhism and Chrisitanity. By John D’Arcy May. Sankt Ottilien: EOS Klosterverlag, 2007. 207 pp.In the course of the past seven years, the European Network of Buddhist-Christian Studies has established itself as a locus of serious dialogue and creative religious reflection. This volume, which emerged out of the sixth conference (in 2005) at the (...) Benedictine Abbey of St. Ottilien in Germany, combines a diversity of contributions on various issues relating to conversion, religious belonging, and multiple religious belonging. At the heart of the volume are two responses (by Christian theologian Perry Schmidt-Leukel and Buddhist theologian José Cabezón) to the highly publicized conversion of Paul Williams from Tantric Buddhism to Roman Catholicism, followed by a reply by Williams himself. These three articles represent a powerful demonstration of religious apologetics at its best. Each offers their critique of the other from a clearly defined religious position, displaying a clear understanding of the views of the other, but arguing unabashedly for the validity or superiority of their own position or theological convictions. Somewhat missing in the reading is an account of Williams’s conversion story, which he developed in An Unexpected Way. But each of the discussants offers a clear enough account of the other so that even those who have not read the book are able to reconstruct the main points of Williams’s narrative and arguments. Against Williams, who juxtaposes Buddhist atheism with Christian theism, Schmidt-Leukel proposes a conception of the absolute which he believes is amenable to both, but which—as Williams later argues—may be representative of neither. Cabezón, for his part, focuses not only on Williams’s theological arguments, but also on his ethical arguments for the superiority of Christianity, objecting that the black-and-white picture presented in a conversion narrative often entails a distortion or oversimplification of the tradition left behind, and pointing to the importance of interconnection and love in Buddhist texts and traditions. While conceding the latter, Williams, in his retort, passionately and eloquently reiterates his arguments for the plausibility of the Christian conception of God, countering one by one the points raised by his respondents. In this, he draws almost exclusively on Thomas Aquinas, which gives power and focus to his arguments but also seems to ignore the presence of other theological voices within the Christian and Roman Catholic tradition. This exercise in apologetics is interesting, not only because of the contents of the arguments, but also because of the tone. While Williams pays heed to Cabezón, [End Page 161] who approaches his conversion from a clearly defined Buddhist perspective, he seems less respectful of the position of Schmidt-Leukel, who attempts to reconcile Buddhist and Christian views of God. The reasons why such reconciliations are unappealing for someone who has converted from the one religion to the other may be many. But it certainly points to the tensions between clear commitment and belonging to a particular religious and theological tradition and the rhetoric of multiple religious belonging.This brings us to some of the other articles collected in this volume. Some focus on the lived reality of multiple belonging in Korea (Thomas Timpte) or in Sweden (Kajsa Ahlstrand) while others focus on personal experience (Thomas Josef Gotz and Ruben Habito) or on the religious or theological grounds for multiple religious belonging (Jorgen Skov Sorensen and Michael von Bruck). All of these contributions point to the reality or the ideality of belonging to more than one religious tradition. It would appear that in the context of religious diversity, such multiple belonging is all but unavoidable. While some point to the false construction of religious boundaries, others dismiss all notions of religious and theological superiority as well as the centrality of truth in religion. In contrast with this, the robust theological debate on matters of truth and difference at the heart of this volume offers a healthy counterbalance and a welcome reminder of the categorical and at times conflicting claims to truth in religion. If religions are taken seriously, multiple religious identity is less evident than sociological data... (shrink)

A Theory of Argument is an advanced textbook intended for students in philosophy, communications studies and linguistics who have completed at least one course in argumentation theory, information logic, critical thinking or formal logic. Containing nearly 400 exercises, Mark Vorobej develops a novel approach to argument interpretation and evaluation. One of the key themes of the book is that we cannot succeed in distinguishing good argument from bad arguments until we learn to listen carefully to others. (...) Part I develops a relativistic account of argument cogency that allows for rational disagreement. Part II offers a comprehensive and rigorous account of argument diagramming. Hybrid arguments are contrasted with linked and convergent arguments, and a novel technique is introduced for graphically recording disagreements with authorial claims. (shrink)

Bayesians since Savage (1972) have appealed to asymptotic results to counter charges of excessive subjectivity. Their claim is that objectionable differences in prior probability judgments will vanish as agents learn from evidence, and individual agents will converge to the truth. Glymour (1980), Earman (1992) and others have voiced the complaint that the theorems used to support these claims tell us, not how probabilities updated on evidence will actually}behave in the limit, but merely how Bayesian agents believe they will behave, (...) suggesting that the theorems are too weak to underwrite notions of scientific objectivity and intersubjective agreement. I investigate, in a very general framework, the conditions under which updated probabilities actually converge to a settled opinion and the conditions under which the updated probabilities of two agents actually converge to the same settled opinion. I call this mode of convergence deterministic, and derive results that extend those found in Huttegger (2015b). The results here lead to a simple characterization of deterministic convergence for Bayesian learners and give rise to an interesting argument for what I call strong regularity, the view that probabilities of non-empty events should be bounded away from zero.

This article investigates new convergences between animal ethics and environmental ethics by focusing on the effects as well as the causes of climate change. Its main objective is to show how a non-anthropocentric approach to climate ethics can increase the potential of collaboration between animal ethics theorists and environmental ethics theorists. It develops an approach that explains how animal ethics, environmental ethics and climate ethics can converge at the theoretical level on the common problem of livestock farming. Then it explains (...) how, from a practical point of view, the vegetarian and vegan diet as well as the vegan lifestyle can be a solution to this common problem. Finally, it replies to major objections in order to develop arguments in favour of a duty not to consume animal products. (shrink)

Many philosophers subscribe to the view that philosophy is a priori and in the business of discovering necessary truths from the armchair. This paper sets out to empirically test this picture. If this were the case, we would expect to see this reflected in philosophical practice. In particular, we would expect philosophers to advance mostly deductive, rather than inductive, arguments. The paper shows that the percentage of philosophy articles advancing deductive arguments is higher than those advancing inductive arguments, which (...) is what we would expect from the vantage point of the armchair philosophy picture. The results also show, however, that the percentages of articles advancing deductive arguments and those advancing inductive arguments are converging over time and that the difference between inductive and deductive ratios is declining over time. This trend suggests that deductive arguments are gradually losing their status as the dominant form of argumentation in philosophy. (shrink)

Much recent work in Cognitive Linguistics and neighbouring disciplines has adopted a so-called usage-based perspective in which generalizations are based on the analysis of authentic usage data provided by computerized corpora. However, the analysis of such data does not always utilize methodological findings from other disciplines to avoid analytical pitfalls and, at the same time, generate robust results. A case in point is the strategy of using corpus frequencies. In this paper, we take up a recently much debated issue (...) from construction grammar concerning the association between verbs and argument-structure constructions, and investigate a construction, the English as-predicative, in order to test the predictive power of different kinds of frequency data against that of a recent, more refined corpus-based approach, the so-called collexeme analysis. To that end, the results of the application of these corpus-based approaches to an analysis of the as predicative are compared with the results of a sentence-completion experiment. Concerning the topic under consideration, collexeme analysis is not only shown to be superior on a variety of theoretical and methodological grounds, it also significantly outperforms frequency as a predictor of subjects’ production preferences. We conclude by pointing out some implications for usage-based approaches. (shrink)

At the centre of Powers' (2019) China and England is an extraordinary forgotten episode in the history of political ideas. There was a time when English radicals critiqued the corruption and injustice of the English political system by contrasting it with the superior example of China. There was a time when they advocated adopting a Chinese conceptual framework for thinking about politics. So dominant and prevalent was the English radicals' use of this framework, that their opponents took to dismissing their (...) points as 'the argument from the Chinese'. In my review of Powers' book, I welcome the profound reconfiguration of our political understandings that knowledge of this historical episode brings. However, I question Powers' framing presumption that the generic problems of any complex society lead to convergence on a single master political value of 'social justice'. Surely there are deep and enduring differences amongst thinkers of political value, even within a single society, let alone across different societies. Taking this point seriously would challenge the simple linear directionality of Powers' story of moral and political progress. (shrink)

David Lewis has shocked the philosophical community with his original version of extreme modal realism according to which “every way that a world could possibly be is a way that some world is”. Logical Space is a plenitude of isolated physical worlds, each being the actualization of some way in which a world could be, that bear neither spatiotemporal nor causal relations to each other. Lewis has given independent, converging arguments for this. One is the argument from the (...) indexicality of actuality, the other an elaborate cost-benefit argument of the inference-to-the-best explanation sort to the effect that a systematic analysis of a number of concepts, including modality, causality, propositions and properties, fares better under his theory than under any rival one that takes a possible world to be either a linguistic entity or an ersatz abstract entity such as a maximal compossible set of properties, propositions or states of affairs. Lewis' legion of critics have confined themselves mostly to attempts at a reductio ad absurdum of his theory or to objections to his various analyses. The indexical argument, on the other hand, has not been subject to careful critical scrutiny. It is the purpose of this paper to show that this argument cannot withstand such scrutiny. Its demise, however, leaves untouched his argument from the explanatory superiority for his extreme modal realism. (shrink)

The arguments of each chapter demonstrate that there is no neutral perspective from which to analyse aesthetic qualities. Such qualities cannot be described as their very perception involves evaluation. In short, the chapters focus on those aspects of a first person perspective that can be considered inter-personal in the sense that they are susceptible of intentional calibration and enculturation. That said, not all chapters approach the theme from the same perspective nor with the same targets in mind. For (...) example, approaching the notion of inter-subjectivity with the intention of defending this possibility against the objection of relativism will yield a different treatment than championing inter-subjectivity in order to reject cultural arrogance, or overly reductive analyses of aesthetic qualities. Yet all chapters converge on the possibility of objectivity grounded in inter-subjectivity. (shrink)

ABSTRACTFeminists have long criticized Rousseau for his patriarchal political theory. But when his lesser-known writings on women from the 1740s are taken into account, including a nearly 900-page manuscript critiquing Montesquieu from a feminist perspective, we see how the early Rousseau robustly converged in feminist ideas with his employer Madame Louise Dupin, before he gradually diverged from this egalitarian school of thought over the course of the 1750s. I add to the evidence of the early Rousseau’s egalitarian (...) response to ‘the woman question’ by showing his philosophical convergence with the feminist arguments of the anonymous ‘Critique of the Spirit of the Laws’ as well as Madame Dupin’s ‘Ouvrage sur les femmes’ – manuscripts largely in his secretarial hand. Through this triangulation of understudied texts, we find that the early Rousseau was not a patriarchal apologist, but rather a feminist secretary and a secretary to a feminist. (shrink)

Smith has argued that moral realism need not be threatened by apparent moral disagreement. One reason he gives is that moral debate has tended to elicit convergence in moral views. From here, he argues inductively that current disagreements will likely be resolved on the condition that each party is rational and fully informed. The best explanation for this phenomenon, Smith argues, is that there are mind-independent moral facts that humans are capable of knowing. In this paper, I seek (...) to challenge this argument—and more recent versions of it—by arguing that historical convergence in moral views may occur for various arational reasons. If such reasons possibly result in convergence—which Smith effectively concedes—then the moral realist would require an additional a posteriori argument to establish that convergence in moral views occurred for the right reasons. Hence, Smith-style arguments, as they stand, cannot be mobilised in support of moral realism. Rather, this investigation demonstrates the necessity of a genuine history of morality for any convergence claim in support of a meta-ethical view. (shrink)

We can provisionally distinguish inference as logically drawing some new result out of given information from argument as advancing reasons in support of a challenged claim. Blair and Johnson place inference beyond the scope of informal logic, and Tou lmin considers inference to be the connection of premises with conclusion in a strong argument. Both approaches are inadequate to inference as distinguished here, and partly as a consequence argument analysts tend unwittingly to mark the distinction as (...) t hat between linked and convergent arguments. Here I urge that there are advantages to treating inference as inference. (shrink)

The aim of this paper is to critically review the traditional typology of argument macrostructures, particularly, the dichotomy between linked and convergent structure. We have found an argument structure that does not fall under one of those five traditional categories: basic, serial, divergent, linked and convergent. We show that the new argument structure, which we call the recursive structure, is not rare-earth, but ubiquitous in real argumentation. Then, we propose and justify a new approach to diagramming arguments (...) of the structure. The new argument structure is really new because arguments of the new structure are analyzed and evaluated differently from those of the other structures, especially from hybrid arguments considered in the literature. In light of the new argument structure, we present a hypothesis why assumptions and exceptions of a defeasible argument play different roles in dialectical settings. (shrink)

Many researchers and intellectuals warn about extreme risks from artificial intelligence. However, these warnings typically came without systematic arguments in support. This paper provides an argument that AI will lead to the permanent disempowerment of humanity, e.g. human extinction, by 2100. It rests on four substantive premises which it motivates and defends: first, the speed of advances in AI capability, as well as the capability level current systems have already reached, suggest that it is practically possible to build (...) AI systems capable of disempowering humanity by 2100. Second, due to incentives and coordination problems, if it is possible to build such AI, it will be built. Third, since it appears to be a hard technical problem to build AI which is aligned with the goals of its designers, and many actors might build powerful AI, misaligned powerful AI will be built. Fourth, because disempowering humanity is useful for a large range of misaligned goals, such AI will try to disempower humanity. If AI is capable of disempowering humanity and tries to disempower humanity by 2100, then humanity will be disempowered by 2100. This conclusion has immense moral and prudential significance.

This paper explores the relationship between psychology and neurobiology in the context of cognitive science. Are the sciences that constitute cognitive science independent and theoretically autonomous, or is there a necessary interaction between them? I explore Fodor's Multiple Realization Thesis (MRT) which starts with the fact of multiple realization and purports to derive the theoretical autonomy of special sciences (such as psychology) from structural sciences (such as neurobiology). After laying out the MRT, it is shown that, on closer inspection, (...) the argument is either circular or self-undermining--the argument either assumes the very autonomy it seeks to demonstrate or the concluded autonomy is contradicted by the theoretical interdependence invoked by the premises of the argument. Next, I explore a concrete example of multiple realization in the explanation of animal behavior: the convergent evolution of jamming avoidance behaviors in three genera of weakly electric fish. Contrary to the image painted by the MRT, the work on these animals involves a high degree of interaction between the various levels of investigation. The fact that our understanding of electric fish behavior involves functional theories and multiple realization without the kind of disunified science that is supposed to follow from such a situation indicates that the mere fact of multiple realization cannot be the basis for an autonomous psychology.

In lieu of an abstract, here is a brief excerpt of the content:A NOTE ON THE RELATION OF PACIFISM AND JUST-WAR THEORY: IS THERE A THOMISTIC CONVERGENCE? 1 GABRIEL PALMER-FERNANDEZ Youngstown State University Youngstown, Ohio FOR CENTURIES, the moral analysis of war began with a consideration of a set of principles which together form the doctrine of the just-war and with a rejection of pacifism. However, several recent studies by Catholic moralists argue that pacifism and just-war theory have much (...) in common and converge in at least one morally important way-namely, they share a presumption against violence. In this note I want to consider whether or not classical just-war theory gives us reason to accept this claim. I will give evidence against it, and suggest that the "original just-war question," as James Turner Johnson calls it, does not begin with aprohibitive presumption or some equivalent constraint on action. If we are to speak of a presumption in classical just-war theory, it is that justice be done for the sake of the common good. Up to very recent times, those Christian denominations which Ernst Troeltsch called the "church-type" (Lutheran, Anglican, Calvinist, and Roman Catholic) upheld a " two-tiered " or "double" morality. A "vocational" pacifism was required of clerical ranks, and the individual Christian was obligated to take up arms for the sake of the common good. For example, prior to the Second Vatican Council, Roman Catholic teaching on war rejected conscientious objection to all war (i.e., pacifism) as an option for Catholics. Manuals of moral theology prior to Vatican 1 I wish to acknowledge the very helpful and detailed comments provided by Richard B. Miller to an earlier version of this paper. 247 248 GABRIEL PALMER-FERNANDEZ II did prohibit the soldier from fighting in an unjust war and made room for subjective doubt about the justice of a particular war. But the consensus among Catholic theologians was both wide and deep. Pacifism for individual Christians did not have any moral-theological justification. It was, in fact, a grave moral error. In spite of this, Vatican II called for a " completely fresh reappraisal of war." 2 The policy of obliterating whole cities enacted during World War II, coupled with the development of nuclear and other indiscriminate weapons of destruction (e.g., incapacitating gases, biological weapons, etc.) and the instability of superpower relations, created an unprecedented condition for which traditional teachings on war seemed woefully inadequate, if not morally dangerous. A new, more far-reaching perspective was needed. And this was to allow for individuals the pacifist option as a second and complementary moral doctrine alongside traditional teaching on war.3 As the American Catholic bishops said in their pastoral letter on war and peace : 2 Pastoral Constitution on the Church in the Modern World, in A. Flannery, 0.P., ed., Vatican Council II: The Conciliar and Post Conciliar Documents (Collegeville, Minn. : Liturgical Press, 1975), par. 80. 3 This development in contemporary Roman Catholic teaching on war and peace has been challenged with considerable force by George Weigel in what has become one of the most controversial studies on the subject. In Tranquillitas Ordinis: The Present Failure and Future Promise of American Catholic Thought on War and Peace (New York: Oxford University Press, 1987), Weigel advances several arguments which are meant to correct what he insists is a failure among Catholic ethicists in the U.S. to develop their tradition, and, indeed, an abandonment of their heritage. " At the level of moral theory," Weigel maintains, "the two classic positions [just-war theory and pacifism] are not reconcilable. The attempt to merge them... tends to corrupt both traditions. Pacifists end up making judgments on military strategy and tactics, and just-war theorists are held accountable to arguments they previously declined to accept.... The net result is to bifurcate morality and politics, and to abandon attempts to apply the tradition of reason to the limit case of the use of armed force in the defense of values-which is precisely the result Murray most feared in his strictures against moralism" (251). For David Hollenbach's rebuttal, see his review essay, "War and Peace in American Catholic Thought: A Heritage Abandoned? " Theological Studies 48 (1987) : 711-727... (shrink)

In this paper we develop a method for finding, under general conditions, explicit and highly uniform rates of convergence for the Picard iteration sequences for selfmaps on bounded metric spaces from ineffective proofs of convergence to a unique fixed point. We are able to extract full rates of convergence by extending the use of a logical metatheorem recently proved by Kohlenbach. In recent case studies we were able to find such explicit rates of convergence in (...) two concrete cases. Our novel method now provides an explanation in logical terms for these findings. This amounts, loosely speaking, to general conditions under which we in this specific setting can transform a ∀∃∀-sentence into a ∀∃-sentence via an argument involving product spaces. This reduction in logical complexity allows us to use the existing machinery to extract quantitative bounds of the sort we need. (shrink)

Natura 2000 is a network of natural sites whose aim is to preserve species and habitats of relevance in the European Union. The policy underlying Natura 2000 has faced widespread opposition from land users and received extensive support from environmentalists. This paper addresses the ethical framework for Natura 2000 and the probable moral assumptions of its main stakeholders. Arguments for and against Natura 2000 were analyzed and classified according to “strong” or “weak” versions of the three main theories (...) of environmental ethics – anthropocentrism, biocentrism, and ecocentrism. Weak (intergenerational) anthropocentrism was found to underlie the Natura 2000 network itself and the positions of environmentalists, while strong (traditional) anthropocentrism pervaded the positions of economic developers. Land users seemed to fall somewhere between weak and strong anthropocentrism. The paper discusses the relation between ethics and different attitudes towards Natura 2000, highlighting some of the implications for the network’s ongoing implementation. It is shown that Natura 2000 achieves a strong reversal of the burden of proof from conservation to economic development and land use change under anthropocentrism. It is argued that the alleged theoretical divide between anthropocentrism and non-anthropocentrism in relation to the burden of proof does not seem to hold in practice. Finally, it is predicted that the weak versions of anthropocentrism, biocentrism, and ecocentrism, are likely to converge extensively in respect to nature conservation policy measures. (shrink)

Debating the interpretation of the Burgess Shale fossil records, Stephen Jay Gould and Simon Conway Morris have formulated two conflicting theses regarding the nature of evolutionary processes. While Gould argued that evolution is essentially a contingent process whose outcomes are unpredictable, Conway Morris claimed that the omnipresence of convergence testifies that it is in fact deterministic, leading to predictable and inevitable outcomes. Their theses have been extensively researched from various perspectives. However, a systematic parallel analysis of the core (...) arguments each of them offered in support of their thesis has been lacking. I argue Conway Morris has successfully exposed the core weaknesses of Gould's thesis and offered a comprehensive account in favor of the major role of convergence in evolutionary history. On the other hand, I will point out some of the weak points in the latter's arguments supporting the deterministic view of life's evolution. Although Conway Morris has been more successful in arguing for the deterministic nature of the evolutionary processes, both theses could be improved if their shortcomings are taken into consideration.

The aim of the present paper is to carry out a comparative study of Immanuel Kant and Jürgen Habermas on democratic governance and citizenship. Both thinkers focus on these two factors but the extent to which these contribute to reinforcing the state and peace has not been investigated by researchers. The present paper questions how cosmopolitanism in comparative and consequential mode: Safeguards peace by presupposing a level of interstate institutional convergence as presented by Kant and Habermas; and Reinforces and (...) innovates democracy on an interstate level not only within the state; and Instead of just safeguarding peace, re‐discovers the political sphere, as presented by Habermas, who on this point develops an array of departures from Kant. The originality of the research derives from the symmetries and asymmetries in Kant and Habermas that extend their arguments on cosmopolitanism to the solidification of democracy and the avoidance of war.

Many attempts have been made to solve Hume's problem. However, the assumptions leading to the problem have remained largely unnoticed. Moreover, since Goodman introduced the predicate "grue", philosophers without relevant mathematical education have been confused. In addition, various delusive arguments from convergence have been presented. In this book, it is maintained that knowledge has to be feasible and relevant and that several solutions fail to meet that demand. It is argued that the crucial presupposition of the problem of (...) induction is that clairvoyance is impossible and that this presupposition is unproven. Generalized Goodman predicates are introduced. To criticize arguments from convergence, the notion of "undecided game" is introduced. A relationship between Zeno's paradox and the problem of induction is revealed. A distinction between "do not know" and "cannot know" is consistently held. It is concluded that, as yet, we do not know the future and that it is impossible to prove that it is impossible to know the future. This book should be useful to professionals in epistemology and philosophy of science, and might be of interest to logicians and mathematicians. (shrink)

Drawing inspiration from the notion of evocation employed in inferential erotetic logic, we defend an ‘evoked questions norm’ on inquiring attitudes. According to this norm, it is rational to have an inquiring attitude concerning a question only if that question is evoked by your background information. We offer two arguments for this norm. First, we develop an argument from convergence. Insights from several independent literatures (20th-century ordinary-language philosophy, inferential erotetic logic, inquisitive epistemic logic, and contemporary (...) zetetic epistemology) all converge on the evoked questions norm. Second, we show that suitably interpreted, the evoked questions norm correctly predicts several underappreciated kinds of bad questions. It does this, in part, by recovering versions of previously defended ignorance and knowledge norms. Some of those bad questions cannot be predicted by either norm singly, but only when corporately taken to reflect a common normative category. We identify this category as evocation. (shrink)

This paper surveys the contributions to the study of argumentation in the two decades since the work of Toulmin and Perelman. Developments include Radical Argumentativism (Anscombre and Ducot), Communication and Rhetoric (American Speech Communication Theory), Informal Logic (Johnson and Blair), Formal Analyses of Fallacies (Woods and Walton), Formal Dialectics (Barth and Krabbe), and Pragma-Dialectics (van Eemeren and Grootendorst). From the survey it is concluded that argumentation theory has been considerably enriched. If the contributions can be made to converge, a (...) sound basis will be created for developing educational methods for producing, interpreting and evaluating argumentative discourse. Thus, argumentation theory may be instrumental in improving the quality of democracy by furthering a reasonable management of differences of opinion. (shrink)

Beginning by offering an overview on legal aesthetic humanisms as a specific embodiment of critical discourse, and discussing the ways the recreation of juridical experience, rationality, and culture underpinning such a criticism, leaving behind monolithic views on textuality, judgment, and subjectivity, positively contributes to unsettling the main assumptions underlying typical understandings of law’s autonomy—mostly those of formal specification of juridical “sources” and “scientific” isolation of legal thought—, this paper argues that simply reproducing aesthetic heterodoxy as the epitome of a humanist (...) ‘alternative to law’, without first debating the very orthodox-heterodox binomial, ends up overlooking the discursive and methodological specificity of law, as a particular experience of practical and normative validity. In this way, it introduces, from an axiological-normative and juridically oriented standpoint, a different—jusaesthetic—argument for re-examining the relationship between law’s praxis, nomos, and community.

Environmentalists care about nature. Often, they reason and act as if they consider nature to be valuable for its own sake, i.e., to have non-instrumental value. Yet, there is a rather widespread reluctance, even among environmentalists, to explicitly ascribe such value to nature. One important explanation of this is probably the thought that it would be mysterious in one way or another if nature possessed such value. In addition, Bryan Norton’s influential convergence hypothesis states that, from a practical (...) point of view, it makes no or little difference whether we ascribe non-instrumental value to nature, given the depth and variety of instrumental value that it possesses. In this paper we provide a counterfactual argument, applying to anyone who genuinely cares about nature, for endorsing non-instrumental value in it. Even if we accept, for the sake of argument, something like the convergence hypothesis, relying on nature’s instrumental value for preservational purposes is risky business for environmentalists. We also briefly consider the mysteriousness-objection to non-instrumental value in nature. We show that with respect to most accounts of non-instrumental value, there is nothing particularly mysterious about nature possessing such value. (shrink)

The possible evolutionary significance of epigenetic memory and codes is a key problem for extended evolutionary synthesis and biosemiotics. In this paper, some less known original works are reviewed which highlight theoretical parallels between current evolutionary epigenetics, on the one hand, and its predecessors in the eco-physiology of higher nervous activity, on the other. Recently, these areas have begun to converge, with first evidence now indicating the possibility of transgenerational epigenetic inheritance of conditional associations in the mammalian nervous system, and (...) related findings in other taxa. This can serve as an interesting example of evolutionary code-making, where the molecular mechanisms underlying arbitrary associations between stimuli involve lasting changes in gene expression that may be transmitted epigenetically across generations, and which in some cases could be further assimilated into the genome over subsequent evolution. Although preliminary, such epigenetic scenarios would also offer an interesting, if so far overlooked parallel to earlier research carried out by one of I.P. Pavlov’s leading students, acad. P.K. Anokhin, and his colleagues, but also by eminent eco-physiologists of the time, several of whom offered arguments for the possibility of unconditional reflexes representing evolutionarily later, specialized, and reduced forms of associative reflexes, from which they may be derived. Although discarded under the growing dominance of modern synthesis, these early epigenetic investigations may deserve renewed attention in the modern context, and if further confirmed, could open essentially new perspectives on the morphofunctional evolution of the nervous system.

This chapter aims to discuss critically the changing values in higher education within the context of culturally, ethnically and religiously plural modern European societies with a special focus on the case of emerging European Islamic higher education institutions. The inquiry argues for the need to rethink the core values in Islamic and western liberal, secular higher education in order to facilitate a new creative engagement between these two distinctive perspectives on higher education that share an intertwined intellectual legacy. The focus (...) of the study is framed by the following questions: Do central educational values of Islam and western secular higher education remain in conflict? To what extent can a critical dialogue of convergence be facilitated between the educational/pedagogic cultures of Islamic and western higher education? Why should such a critical engagement be based on a shared relational ethics of respecting the dignity of difference and recognition of mutual interdependence? The study adopts a phenomenology- infomed critical, comparative analysis method while exploring the topic within its historical and contempoaray dimensiosns. The original contribution of the inquiry lies in its reflective engagement with the Islamic and western values of higher education and developing a distinctive conceptual framework to facilitate a new pedagogic dialogue among the communities of learners and teachers coming from these educational cultures who increasingly share the same social space. After presenting the aims and context of the inquiry, a brief historical account of Islamic and western values of higher education will be provided. This will be followed by discussing the arguments supporting the incompatibility of Islamic and western values of education. The incompatibility thesis will be deconstructed by critically examining its logic of binary literalism. By drawing on the evidence suggesting presence of a shared reflective, critical educational heritage between Islam and the West, the chapter argues for the need to revive these forgotten traditions of pedagogic curiosity and critical openness to inspire a new cross-pollinating dialogue capable of acknowledging the dignity of being different and recognizing the reality of sharing an interdependent world.

The basic thesis of Russell Powell’s Contingency and Convergence: Toward a Cosmic Biology of Body and Mind is that law-like evolutionary processes produce humanlike cognitive capacities, rendering such capacities common in the universe. There is an important caveat; key aspects of human cognition, those that undergird cumulative culture, are entirely contingent and likely very rare. To defend this thesis, Powell marshals a wealth of evidence from a variety of disciplines and develops some singular theoretical tools. Unfortunately, at a (...) number of key points in the book Powell simply ignores contradicting evidence and other plausible approaches to thinking about the history of life on our planet. Thus Powell’s argument is, at best, a weak how possibly argument—another Just-So story mixing science with speculation. Nonetheless, the flaws in the book are instructive. They exemplify how a kind of anthropocentrism continues to shape the philosophy of biology and, arguably, biology itself, placing humans at the apex of evolution and demanding that the study of life must ultimately be about us. In effect, Powell offers a rationalization for why we can treat humans as the measure of all things, asserting our continuity with the rest of life on the planet, while at the same time maintaining our uniqueness. Interrogating his argument proves a useful exercise in identifying why this kind of anthropocentrism is implausible. (shrink)

Tracing key biblical topics recurrent in Grotian and Hobbesian discourses on the church-state relationship, The Sovereign and the Prophetsexamines Spinoza's Old Testament interpretation in the Theologico-political Treatiseand elucidates his effort to establish what Hobbes could not adequately offer to the Dutch: the liberty to philosophize. Fukuoka develops an original method for understanding seventeenth-century biblical arguments as a shared political paradigm. Her in-depth analysis reveals the discourses that converged on the question, 'Who stands immediately under God to mediate His will to (...) the people?' This subtly nuanced theme not only linked major theoreticians diachronically--from the Remonstrants such as Grotius to the anti-Hobbesian jurist Ulrik Huber (1636-1694)--but also synchronically built the axis of resonances and dissonances between Leviathanand the Theologico-political Treatise.
