The works of the Tibetan logician Phya pa Chos kyi seng ge (1109–1169) make abundant use of a particular type of argument that I term ‘argument by parallels’. Their main characteristic is that the instigator of the argument, addressing a thesis in a domain A, introduces a parallel thesis in an unrelated domain B. And in the ensuing dialogue, each of the instigator’s statements consists in replicating his interlocutor’s previous assertion, mutatis mutandis, in the other domain (...) (A or B). I show that such a dialogue involves two parallel arguments that develop in an intersecting zigzag pattern, and discuss the principles involved in the establishment of the conclusion from the perspective of parity of reasoning and analogical argument. I examine the overall rhetorical strategy directing the use of arguments by parallels and the pedagogical and explanatory functions they can serve. I also evaluate the plausibility of their use in Phya pa Chos kyi seng ge’s works mirroring a contemporary practice of oral debate, and reflect on the status of such arguments in the framework of Indo-Tibetan logic.

By Parallel Reasoning is the first comprehensive philosophical examination of analogical reasoning in more than forty years designed to formulate and justify standards for the critical evaluation of analogical arguments. It proposes a normative theory with special focus on the use of analogies in mathematics and science. In recent decades, research on analogy has been dominated by computational theories whose objective has been to model analogical reasoning as a psychological process. These theories have devoted little attention to normative questions. In (...) this book Bartha proposes that a good analogical argument must articulate a clear relationship that is capable of generalization. This idea leads to a set of distinct models for the critical analysis of prominent forms of analogical argument. The same core principle makes it possible to relate analogical reasoning to norms and values of scientific practice. Reasoning by analogy is justified because it strikes an optimal balance between conservative values, such as simplicity and coherence, and progressive values, such as fruitfulness and theoretical unification. Analogical arguments are also justified by appeal to symmetry--like cases are to be treated alike. In elaborating the connection between analogy and these broad epistemic principles, By Parallel Reasoning offers a novel contribution to explaining how analogies can play an important role in the confirmation of scientific hypotheses.

In this work, Paul Bartha proposes a normative theory of analogical arguments and raises questions and proposes answers regarding the criteria for evaluating analogical arguments, the philosophical justification for analogical reasoning, and the place of scientific analogies in the context of theoretical confirmation.

This paper discusses the method when an argument is refuted by a parallel argument since the flaw of the parallel argument is clearly displayed. The method is explicated, examined and compared with two other general methods.

This monograph proposes a new way of studying the different forms of correlational inference, known in the Islamic jurisprudence as qiyās. According to the authors’ view, qiyās represents an innovative and sophisticated form of dialectical reasoning that not only provides new epistemological insights into legal argumentation in general but also furnishes a fine-grained pattern for parallel reasoning which can be deployed in a wide range of problem-solving contexts and does not seem to reduce to the standard forms of analogical reasoning (...) studied in contemporary philosophy of science and argumentation theory. After an overview of the emergence of qiyās and of the work of al-Shīrāzī penned by Soufi Youcef, the authors discuss al-Shīrāzī’s classification of correlational inferences of the occasioning factor. The second part of the volume deliberates on the system of correlational inferences by indication and resemblance. The third part develops the main theoretical background of the authors’ work, namely, the dialogical approach to Martin-Löf's Constructive Type Theory. The authors present this in a general form and independently of adaptations deployed in parts I and II. Part III also includes an appendix on the relevant notions of Constructive Type Theory, which has been extracted from an overview written by Ansten Klev. The book concludes with some brief remarks on contemporary approaches to analogy in Common and Civil Law and also to parallel reasoning in general. (shrink)

There is now a burgeoning literature on evolutionary debunking arguments (EDAs) against moral beliefs, but perhaps surprisingly, a relatively small literature on EDAs against religious beliefs. There is an even smaller literature comparing the two. This essay aims to further the investigation of how the two sorts of arguments compare with each other. To begin with, I shall offer some remarks on how to best formulate these arguments, focusing on four different formulations that one can discern in the literature and (...) that can be applied to both sorts of beliefs. I shall then go on to make a series of comparisons regarding the relative vulnerabilities of moral beliefs and theistic religious beliefs to these four arguments, suggesting that there are a number of respects in which theistic religious beliefs are somewhat less liable than moral beliefs to be undercut by EDAs.

The Tibetan Buddhist logician Phya pa Chos kyi seng ge devoted a large part of his discussion on argumentation to arguments by consequence. Phya pa distinguishes in his analysis arguments by consequence that merely refute the opponent and arguments by consequence that qualify as probative. The latter induce a correct direct proof which corresponds to the reverse form of the argument by consequence. This paper deals with Phya pa’s classification of probative consequences based on the type of the logical (...) reason involved. I first establish the basis of Phya pa’s classification—the typology of logical reasons in inference-for-oneself—with a special attention to logical reasons consisting in the ‘apprehension of something incompatible [with the negandum]’ and among them the specific case of the ‘apprehension of the cause of something incompatible [with the negandum]’. The treatment of the latter is shown to be instrumental in Phya pa’s classification, as well as in explaining the divergences that occur in the models adopted by his successors, such as gTsang nag pa brTson ʾgrus seng ge and mTshur ston gZhon nu seng ge. Turning to Phya pa’s effective application of this typology when he resorts himself to arguments by consequence, I examine Phya pa’s rephrasing, in the form of four arguments by consequence, of the discussion on the relation between the two realities found in the Saṃdhinirmocanasūtra and relate it to a parallel discussion in an earlier Madhyamaka work by rGya dmar ba Byang chub grags. I compare the variant versions of these four arguments in three Madhyamaka works of Phya pa and show that the differences pertaining to the identification of the type of the logical reason result from apparently insignificant variations in the formulation of each of the arguments. In the conclusion, I discuss the potential philosophical or practical interest of such a classification. (shrink)

Matt King has recently argued that the manipulation argument against compatibilism does not succeed by employing a dilemma: either the argument infelicitously relies on incompatibilist sourcehood conditions, or the proponent of the argument leaves a premise of the argument undefended. This article develops a reply to King’s dilemma by showing that incompatibilists can accept its second horn. Key to King’s argument for the second horn’s being problematic is “the parallel manipulation argument.” I argue that (...) King’s use of this argument is problematic, but I suggest that a (modified) parallel manipulation argument is effective for a different, though more restricted, purpose. (shrink)

Nowadays, there is a quite considerable amount of literature on the use of analogy or more generally of inferences by parallel reasoning in contemporary legal reasoning, and particularly so within Common Law. These studies are often motivated by researches in artificial intelligence seeking to develop suitable software-support for legal reasoning. Recently; Rahman/Iqbal/Soufi (2020) developed a dialogical approach in the framework of Constructive Type Theory to what in Islamic Jurisprudence was called qiyās or correlational inferences. In their last chapter the authors (...) suggested that such an approach contributes to the study of patterns of reasoning by precedent cases within contemporary common Law. In the present paper we will further motivate the deployment within Civil and Common Law of the dialogical framework developed in Rahman/Iqbal/Soufi (2020). After a presentation of Scott Brewer's take on analogy within Common Law, that has striking structural similarities to reasoning by precedent case rooted in ratio legis (known in Islamic Jurisprudence as qiyās al-'illa or correlational inference by the occasioning factor), we will illustrate the implementation of the framework with a brief discussion of some cases of legal reasoning based in Spanish Civil Law but where the accent is put in the emerging ruling rather than in the existing of a case as in Common Law. Moreover; quite surprisingly, the case under study suggests that even cases of Law-interpretation fit the argumentation pattern of qiyās al-'illa. A caveat: in the present paper we will focus mainly in discussing the dynamics of the meaning constitution involved rather than in setting the rules of the underlying dialogical framework, the latter is the subject of a follow-up paper.

This paper presents the main aspects of the views of the Tibetan logician Phya pa Chos kyi seng ge (1109–1169) on argumentation “by consequence” (thal ʼgyur, Skt. prasaṅga) based on his exposition of the topic in the fifth chapter of his Tshad ma yid kyi mun sel and on a parallel excursus in his commentary on Dharmakīrti’s Pramānaviniścaya. It aims at circumscribing primarily the nature and function of consequences (thal ʼgyur/thal ba) for this author—in particular the distinction between “proving consequences” (...) and “refuting consequences”—and the form prescribed for their enunciation in the context of debate. In addition to pointing out differences with the systems adopted by his predecessors, contemporaries and successors, the paper also discusses some of the similarities and differences between Phya pa’s understanding of argumentation by consequence and the notion of reductio ad absurdum in Western logic.

The paper discusses the structure, applications, and plausibility of the much-used parallel-case argument for workplace democracy. The argument rests on an analogy between firms and states according to which the justification of democracy in the state implies its justification in the workplace. The contribution of the paper is threefold. First, the argument is illustrated by applying it to two usual objections to workplace democracy, namely, that employees lack the expertise required to run a firm and that only (...) capital suppliers should have a say over the governance of the firm. Second, the structure of the argument is unfolded. Third, two salient similarities between firms and states regarding their internal and external effects and the standing of their members are addressed in order to asses the potential and limits of the argument, as well as three relevant differences regarding the voluntariness of their membership, the narrowness of their goals, and the stiffness of the competition they face. After considering these similarities and differences, the paper contends that the the parallel-case argument provides a sound reason in favor of democracy in the workplace—a reason, however, that needs to be importantly qualified and that is only pro tanto.

The article is an investigation of a certain form of argument that refers to Leibniz’s Law as its inference ticket (where Leibniz’s Law is understood as the thesis that if x=y.

I show to be unsuccessful several attempts to demonstrate the possibility of time without change. Consideration of the most prominent of these arguments (by Sydney Shoemaker) then leads to the formulation of a general argument: evidence which justifies a claim that a certain amount of time has elapsed also justifies a claim that continuous change has occurred during the period. Hence there is a sound basis for the relationist claim that there is no time without events.

Compositionality has been a central concept in linguistics and philosophy for decades, and it is increasingly prominent in many other areas of cognitive science. Its status, however, remains contentious. Here, I reassess the nature and scope of the principle of compositionality (Partee, 1995) from the perspective of psycholinguistics and cognitive neuroscience. First, I review classic arguments for compositionality and conclude that they fail to establish compositionality as a property of human language. Next, I state a new competence argument, acknowledging (...) the fact that any competent user of a language L can assign to most expressions in L at least one meaning which is a functiononlyof the meanings of the expression's parts and of its syntactic structure. I then discuss selected results from cognitive neuroscience, indicating that the human brain possesses the processing capacities presupposed by the competence argument. Finally, I outline a language processing architecture consistent with the neuroscience results, where semantic representations may be generated by a syntax‐driven streamandby an “asyntactic” processing stream, jointly or independently. Compositionality is viewed as a constraint on computation in the former stream only. (shrink)

This book advertises itself as an exploration of the world-time parallel, that is, the parallel between the modal dimension, on the one hand, and the temporal dimension, on the other. It is that, and much more. As the authors point out, there is reasonable agreement that we can model times, through temporal logic, in ways that are analogous to those by which we model modality through the logic of possible worlds. But this formal parallel has almost universally been taken to (...) be a merely formal parallel: thus it is held that no metaphysical conclusions ought to be drawn from it. Thus, it is generally thought that one is free to accept an argument for actualism, say, but to reject a parallel argument for presentism. Rini and Cresswell compellingly argue that this is a mistake: the temporal and the modal are more than merely formally analogous. (shrink)

Euclidean geometry, as presented by Euclid, consists of straightedge-and-compass constructions and rigorous reasoning about the results of those constructions. We show that Euclidean geometry can be developed using only intuitionistic logic. This involves finding “uniform” constructions where normally a case distinction is used. For example, in finding a perpendicular to line L through point p, one usually uses two different constructions, “erecting” a perpendicular when p is on L, and “dropping” a perpendicular when p is not on L, but in (...) constructive geometry, it must be done without a case distinction. Classically, the models of Euclidean geometry are planes over Euclidean fields. We prove a similar theorem for constructive Euclidean geometry, by showing how to define addition and multiplication without a case distinction about the sign of the arguments. With intuitionistic logic, there are two possible definitions of Euclidean fields, which turn out to correspond to different versions of the parallel postulate.We consider three versions of Euclid’s parallel postulate. The two most important are Euclid’s own formulation in his Postulate 5, which says that under certain conditions two lines meet, and Playfair’s axiom, which says there cannot be two distinct parallels to line L through the same point p. These differ in that Euclid 5 makes an existence assertion, while Playfair’s axiom does not. The third variant, which we call the strong parallel postulate, isolates the existence assertion from the geometry: it amounts to Playfair’s axiom plus the principle that two distinct lines that are not parallel do intersect. The first main result of this paper is that Euclid 5 suffices to define coordinates, addition, multiplication, and square roots geometrically.We completely settle the questions about implications between the three versions of the parallel postulate. The strong parallel postulate easily implies Euclid 5, and Euclid 5 also implies the strong parallel postulate, as a corollary of coordinatization and definability of arithmetic. We show that Playfair does not imply Euclid 5, and we also give some other independence results. Our independence proofs are given without discussing the exact choice of the other axioms of geometry; all we need is that one can interpret the geometric axioms in Euclidean field theory. The independence proofs use Kripke models of Euclidean field theories based on carefully constructed rings of real-valued functions. “Field elements” in these models are real-valued functions.

This paper will look at Kant’s views of the aesthetic experience, in relationship to Buddhist philosophical and political discussions of art and social organization. The primary focus in Kantian literature explores the relationship between free and dependent beauty, as well as Kant’s paradox of taste. The central argument of the Kantian portion is going to navigate the paradox of taste via Graham Priest’s epistemic and conceptual distinction pertaining to the limits of thought. Secondly, I shall contextualize the debate with (...) similar argumentation found in medieval Tibetan literature, by thinkers such as Tsongkhapa and Drakpa Gyaltsen. Lastly, I shall look at the political and artistic state of affairs in Yuan and Ming Dynasties and assert the applicability of both Kantian and Tibetan discussions of effibility in the context of Tibetan poetry and Thangkas.

Gilbert Harman has presented an argument to the effect that if S knows that p then S knows that any evidence for not-p is misleading. Therefore S is warranted in being dogmatic about anything he happens to know. I explain, and reject, Sorensen's attempt to solve the paradox via Jackson's theory of conditionals. S is not in a position to disregard evidence even when he knows it to be misleading.

A plausible desideratum for an account of the nature of objects, at, and across time, is that it accommodate the phenomenon of vagueness without locating vagueness in the world. A series of arguments have attempted to show that while universalist perdurantism – which combines a perdurantist account of persistence with an unrestricted mereological account of composition – meets this desideratum, endurantist accounts do not. If endurantists reject unrestricted composition then they must hold that vagueness is ontological. But if they embrace (...) unrestricted composition they are faced with the problem of the many, and cannot plausibly accommodate vagueness. This paper disambiguates two related sub-problems of the problem of the many, and argues that universalist perdurantism is not superior to universalist endurantism with respect to either of these.

Magical ersatzism is the view that possible worlds are primitive abstract entities. In On the Plurality of Worlds, David Lewis presented what appeared to many to be a devastating argument against magical ersatzism. In this paper, I show that Lewis’ central argument does not succeed. Magical ersatzism remains a viable theory of possible worlds.

Deflationists about truth typically deny that truth is a causal-explanatory property. However, the now familiar 'success argument' attempts to show that truth plays an important causal-explanatory role in explanations of practical success. Deflationists have standardly responded that the truth predicate appears in such explanations merely as a logical device, and that therefore truth has not been shown to play a causal-explanatory role. I argue that if we accept Jackson and Pettit's account of causal explanations, the standard deflationist response is (...) inconsistent, for on this account even logical properties can be causally explanatory. Therefore the deflationist should remain neutral as to whether truth is a causal-explanatory property, and focus instead on the claim that truth, if it is a property, is a merely logical one.

I examine Paul Boghossian's recent attempt to argue for scepticism about logical rules. I argue that certain rule- and proof-theoretic considerations can avert such scepticism. Boghossian's 'Tonk Argument' seeks to justify the rule of tonk-introduction by using the rule itself. The argument is subjected here to more detailed proof-theoretic scrutiny than Boghossian undertook. Its sole axiom, the so-called Meaning Postulate for tonk, is shown to be false or devoid of content. It is also shown that the rules of (...) Disquotation and of Semantic Ascent cannot be derived for sentences with tonk dominant. These considerations deprive Boghossian's scepticism of its support. (shrink)

A familiar form of scepticism supposes that knowledge requires infallibility. Although that requirement plays no role in our ordinary epistemic practices, Barry Stroud has argued that this is not a good reason for rejecting a sceptical argument: our ordinary practices do not correctly reflect the requirements for knowledge because the appropriateness-conditions for knowledge attribution are pragmatic. Recent fashion in contextualist semantics for 'knowledge' agrees with this view of our practice, but incorrectly. Ordinary epistemic evaluations are guided by our conception (...) of a person's standing with regard to the reasons that there are for and against the truth of a belief. Thus the objection from our ordinary practices is sound: fallibility is not an epistemological shortcoming, and a convincing sceptical argument must use only requirements which figure in ordinary epistemic practice.

Meta-ethical discussions commonly distinguish 'subjectivism' from 'emotivism', or 'expressivism'. But Frank Jackson and Philip Pettit have argued that plausible assumptions in the philosophy of language entail that expressivism collapses into subjectivism. Though there have been responses to their argument, I think the responses have not adequately diagnosed the real weakness in it. I suggest my own diagnosis, and defend expressivism as a viable theory distinct from subjectivism.

But in many orders of beauty, particularly those of the finer arts, it is requisite to employ much reasoning, in order to feel the proper sentiment; and a false relish may frequently be corrected by argument and reflection. There are just grounds to conclude, that moral beauty partakes much of this latter species, and demands the assistance of our intellectual faculties, in order to give it a suitable influence on the human mind (EPM, 173).

In an earlier paper, "The Indeterminacy of Republican Policy," I argued that in an important class of cases, republican political theory, as formulated by Philip Pettit, does not have determinate implications for policy. Pettit has replied that my argument was based on a conception of freedom as nondomination that is not his own. In the present paper, I explore the two ways of understanding republican freedom. I first suggest that they may not, in the end, be very different. I (...) then note that if a sharp difference is restored, my conception may have some desirable features. (shrink)

This paper compares two proposed solutions to the liar paradox, both of which involve revisions to classical semantics. The first, that of truth value gaps, denies that all sentences are true or false. The second, that of truth value gluts, asserts that some sentences are true and false. A natural question about these proposals is, ?Do they offer equally good (or bad) solutions, or is one better than the other?? Parsons 1990 suggested an answer to this question, arguing that for (...) every problem for one solution, there is a parallel problem for the other. Since then, several people have given arguments for and against the idea that the two face parallel problems. This paper advances the debate in two ways. First, it answers four attempts by Graham Priest to reject the parallel. In particular, it discusses alleged advantages for the gap solution with regard to the teleological account of truth, an extended liar paradox, Berry's paradox, and inexpressibility. Second, it discusses where, if anywhere, the parallel may be broken. (shrink)

In a recent paper, Lyngzeidetson [1990] has claimed that a type of parallel computer called the ‘Connection Machine’ instantiates architectural principles which will ‘revolutionize which "functions" of the human mind can and cannot be modelled by (non-human) computational automata.’ In particular, he claims that the Connection Machine architecture shows the anti-mechanist argument from Gödel's theorem to be false for at least one kind of parallel computer. In the first part of this paper, I argue that Lyngzeidetson's claims are not (...) supported by his arguments; in the second part I consider some other aspects of parallel computation which may be of theoretical significance in cognitive science.

According to First-Person Realism, one's own first-person perspective on the world is metaphysically privileged in some way.

In response to the increasingly popular manipulation argument against compatibilism, some have argued that libertarian accounts of free will are vulnerable to parallel manipulation arguments, and thus manipulation is not uniquely problematic for compatibilists. The main aim of this article is to give this point a more detailed development than it has previously received. Prior attempts to make this point have targeted particular libertarian accounts but cannot be generalized. By contrast, I provide an appropriately modified manipulation that targets all (...) libertarian accounts of freedom and responsibility—an especially tricky task given that libertarian accounts are a motley set. I conclude that if manipulation arguments reveal any theoretical cost then it is one borne by all accounts according to which we are free and responsible, not by compatibilism in particular.

With more countries implementing Open Notes, the practice of providing patients with unhindered access to their clinical visit notes, research on this practice is finally increasing. Many studies report positive findings, especially around self-reported outcomes, such as feeling more in control of one’s care, increased medication adherence and a strengthened patient–doctor relationship. 1 However, comparatively less research has been done on the potential ramifications that may also arise from Open Notes. Blease’s recent article underscores this and demonstrates why Open Notes (...) must also be considered in terms of nocebo effects, negative side effects that arise from negative expectations. 2 The article presents a compelling and well-thought-out argument for how nocebo effects may vary across different populations by linking patient–clinician communication inequalities with and by presenting preliminary evidence of nocebo effects. Blease’s argument does not detract from Open Notes, but rather takes a balanced approach by imploring us... (shrink)

Evolutionary debunking arguments are arguments that appeal to the evolutionary origins of evaluative beliefs to undermine their justification. This paper aims to clarify the premises and presuppositions of EDAs—a form of argument that is increasingly put to use in normative ethics. I argue that such arguments face serious obstacles. It is often overlooked, for example, that they presuppose the truth of metaethical objectivism. More importantly, even if objectivism is assumed, the use of EDAs in normative ethics is incompatible with (...) a parallel and more sweeping global evolutionary debunking argument that has been discussed in recent metaethics. After examining several ways of responding to this global debunking argument, I end by arguing that even if we could resist it, this would still not rehabilitate the current targeted use of EDAs in normative ethics given that, if EDAs work at all, they will in any case lead to a truly radical revision of our evaluative outlook.

In this excellent, clearly written, and clear sighted book, Terence Cuneo defends moral realism from a variety of different attacks. Cuneo is particularly interested in the charge that the moral facts that realists posit are suspect because they are unnatural and queer. He addresses a number of arguments against realism, not least Mackie's Argument from Queerness. What makes the book distinctive is its strategy. Cuneo is keen to show that moral facts and epistemic facts are very similar, if not (...) inseparably intertwined in many cases, and to argue that we should not find moral realism odd since we do not find epistemic realism odd. Indeed, towards the start he begins with a number of quotations from those who have cast doubt on moral realism, including Mackie, who themselves point out that there could be parallels between the moral and epistemic cases, but who do not pursue those parallels to any great degree. Cuneo aims to fill this gap, and to do so in favour of the realist. I agree entirely with Cuneo's conclusions and …. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Islamic Disputation Theory: The Uses & Rules of Argument in Medieval Islam by Larry Benjamin MillerKhaled El-RouayhebLarry Benjamin Miller. Islamic Disputation Theory: The Uses & Rules of Argument in Medieval Islam. Logic, Argumentation and Reasoning 21. Cham: Springer 2020. Pp. xviii + 143. Hardback, €77.99.Very few unpublished PhD dissertations have had a formative influence on a field. One of the precious few is Larry Miller's Princeton (...) dissertation from 1984 on Islamic disputation theory. It proposed an original and compelling account of the development of the discipline, from the earliest extant Arabic works in the tenth century to the composition of classic madrasa handbooks in the late thirteenth century. It has been cited regularly in the past decades and has served as the starting point for all later studies of Arabic/Islamic dialectics in European languages. The fact that it has finally been published is a fitting tribute to a study that is even more admirable for having been written when many of the primary sources were still only available as manuscripts.Part of the explanation for why the dissertation was not published sooner may be that its author did not pursue an academic career. And as he states in a short preface, he has not kept abreast of all relevant studies and editions that have appeared since his dissertation. A thorough revision and update has therefore not been possible. Though some minor corrections and revisions have been made, the book is still by and large the influential 1984 dissertation, now made available with a short introduction by Walter Young, one of the leading younger scholars in the field, along with helpful indices of proper names and subjects.Miller's narrative begins with Arabic works on disputation (jadal) by a number of theologians from the late ninth and tenth centuries, such as Ibn al-Rāwandī (d. 911), [End Page 518] al-Ash'arī (d. 935), and the Karaite Jewish scholar al-Qirqisānī (d. ca. 960). The basic assumption was that a questioner (sā'il) would ask a claimant (mu'allil) (i) what his view is; (ii) what the ground or reason ('illa) for that view is; (iii) the appropriateness of the ground/reason for the view; and (iv) to verify the ground/reason by showing it to be commensurate with the view. The ground/reason for the theological dialecticians was standardly an entity or property, not a premise. The reasoning tended to be informal and analogical, as opposed to explicitly making syllogistic deductions from quantified premises.Parallel to this theological tradition of jadal, there was an Arabic Aristotelian tradition that took its point of departure from Aristotle's Topics, translated into Arabic more than once in the period from the late eighth to the early tenth centuries. Though also often referred to as jadal, this tradition, represented by the writings of al-Farabi (d. 950), Avicenna (d. 1037), and Averroes (d. 1198), retained distinct features. It tended to deny any epistemic value to dialectics, instead seeing it as useful only insofar as it provided logical training. For the Aristotelian/Neoplatonic philosophers, the pursuit of truth was the preserve of demonstrative syllogism (burhān). Whereas the theological dialecticians envisaged a claimant (mu'allil) and a questioner (sā'il), with the burden of proof on the former, the philosophical tradition had a questioner (sā'il) seek, in the manner of Socratic elenchus, to elicit from a respondent (mujῑb) a series of answers that would allow the construction of a syllogism whose conclusion contradicted the respondent's initial position.From the time of al-Ghazali (d. 1111), Islamic theologians tended to take over the syllogistic ideal of reasoning from the philosophers, perhaps explaining why theological writings on jadal trail off after the eleventh century. The informal, analogical jadal tradition continued, however, in the writings of Islamic jurists. From the eleventh century, scholars such as Abū Isḥāq al-Shīrāzī (d. 1083) and al-Juwaynī (d. 1085) wrote works on jadal in which the examples are disputes about questions of Islamic law and the disputants are partisans of the various legal schools. This tradition of what Miller calls "juristic dialectics" (74, 95) later adopted some... (shrink)

One of the most fundamental premises of feminist philosophy is the assumption of an invidious asymmetry between the genders that has to be overcome. Parallel to this negative account of asymmetry we also find a positive account, developed in particular within the context of so-called feminist philosophies of difference. I explore both notions of gender asymmetry. The goal is a clarification of the notion of asymmetry as it can presently be found in feminist philosophy. Drawing upon phenomenology as well as (...) feminist difference theory , I argue that a gender asymmetry does exist that cannot-as in the first assumption-be transformed into symmetry. (shrink)

I exploit parallel considerations in the philosophy of mind and metaethics to argue that the reasoning employed in an important argument for panpsychism overgeneralizes to support an analogous position in metaethics: panmoralism. Next, I raise a number of problems for panmoralism and thereby build a case for taking the metaethical parallel to be a reductio ad absurdum of the argument for panpsychism. Finally, I contrast panmoralism with a position recently defended by Einar Duenger Bohn and argue that the (...) two suffer from similar problems. I conclude by drawing some general lessons for panpsychism. (shrink)

This paper argues that the problem of expertise calls for a rapprochement between social epistemology and argumentation theory. Social epistemology has tended to emphasise the role of expert testimony, neglecting the argumentative function of appeals to expert opinion by non-experts. The first half of the paper discusses parallels and contrasts between the two cases of direct expert testimony and appeals to expert opinion by our epistemic peers, respectively. Importantly, appeals to expert opinion need to be advertised as such, if (...) they are to sway an epistemic peer. The second half of the paper sketches a theoretical framework for thinking about assessments of expertise in a unified way, via a ‘default and challenge’ model that emphasises the need for a version of conversational scorekeeping. It is through such scorekeeping that interlocutors can track and coordinate their differences in epistemic outlook. The paper concludes with a genealogical perspective on the function of (attributions of) expertise: acceptance of another’s appeal to expert opinion may be construed as tacit agreement that inquiry, for now, has been taken far enough.

Mizrahi contends that other epistemologicaltheories can be supported by parallel self-defeat arguments. I argue that the self-defeat arguments for other theories either (a) are compatible with PC and thus present no problem, or (b) have a false premise, unlike the self-defeat argument for PC.

I trace the development of arguments for the consistency of non-Euclidean geometries and for the independence of the parallel postulate, showing how the arguments become more rigorous as a formal conception of geometry is introduced. I analyze the kinds of arguments offered by Jules Hoüel in 1860-1870 for the unprovability of the parallel postulate and for the existence of non-Euclidean geometries, especially his reaction to the publication of Beltrami’s seminal papers, showing that Beltrami was much more concerned with the existence (...) of non-Euclidean objects than he was with the formal consistency of non-Euclidean geometries. The final step towards rigorous consistency proofs is taken in the 1880s by Henri Poincaré. It is the formal conception of geometry, stripping the geometric primitive terms of their usual meanings, that allows the introduction of a modern fully rigorous consistency proof. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:160 HISTORY OF PHILOSOPHY A PLATONIC PARALLEL IN THE DISSOI LOGOI The Dissoi Logoi or Two-/old Arguments (Diels-Kranz, II, 405-416) is an anonymous sophistic treatise written in literary Doric at some time subsequent to the end of the Peloponnesian War in 404-403.1 As early as 1911, A. E. Taylor wrote that the treatise "must be seriously reckoned with in any attempt to reconstruct the history of Greek thought in (...) the generation immediately anterior to Plato." 2 But scholars have been slow to take up Taylor's challenge. From those writing in English we have had little beyond the summary in Kathleen Freeman's Companion a and the papers of Adolfo Levi4 and E. S. Ramage." There is not even a full English translation in print, s In this paper I shall call attention to one brief passage which seems to me to be of exceptional interest since it offers a solution to a type of sophistical argument which occurs in Plato's Euthydemus.

With respect to the assertion that the same man both is and is not, I put the following question: "Does he exist with respect to some particular thing, or just in general?"

Is it supposed that the opponent has put forward an argument purporting to demonstrate (a) that the same man both is and is not, or (b) that a particular man, thought to exist, does not in fact exist?

The obvious way of dealing with this argument is to make precisely the distinction made by the author of the Dissoi Logoi at V, 15: we should say to Dionysodorus, "Your conclusion that the friends of Cleinias wish for his death is the result of an illegitimate step: you went from 'you wish him not to be ignorant' to 'you wish him not to be'. To have made this step is to have ignored the distinction between existence with respect to some particular thing, i.e., ignorance, and existence in general."

This work argues from a social-theoretical perspective for the view that every concept of 'gender' remains bound to reproduction. As every culture is interested in its continuity, it distinguishes individuals according to their assumed possible contribution to reproduction and so develops a fundamental dual classification. Subsequent gender categories are necessarily derived from this one. The conceptual and empirical arguments for this thesis are illustrated through an imagined dystopia. There I envision under what conditions a complete dissociation of the concepts 'sex' (...) and 'gender' from the old dual distinction would be possible and in what way a multiplicity of genders would be accomplished.

Benton Stidd has defended the position that punctuationists are not wrong about the inadequacy of the synthetic theory of evolution for explaining evolution. The thrust of his defense is that arguments to the contrary by Thompson involve a rational reconstruction along logical empiricist lines, which is insensitive to historical and social forces in a way that the Kuhnian Weltanschauung view that he espouses is not. I argue in this paper that Stidd has entirely misunderstood my arguments, that the soundness of (...) my arguments does not depend on acceptance of logical empiricism , and that Stidd fails to establish that punctuated equilibria is a new "paradigm".

The Assimilation Argument purports to show that libertarians cannot plausibly distinguish supposed exercises of free will from random outcomes that nobody would count as exercises of free will. If this argument is sound, libertarians should either abandon their position or else concede that free will is a mystery. Drawing on a parallel with the Manipulation Argument against compatibilism, Christopher Franklin has recently contended that the Assimilation Argument is unsound. Here I defend the Assimilation Argument and (...) the Rollback Argument, a second challenge to libertarianism that Franklin rejects. My aim in doing so is to underscore the force of these challenges, and thereby to resist what appears to be an emerging trend in the literature. By not coming to grips with the kind of power that libertarians must secure, many writers have recently downplayed or dismissed the pressing worry for libertarianism. (shrink)
