a recent paper, Fábio Perin Shecaira proposes a defence of Waller’s deductivist schema for moral analogical argumentation. This defence has several flaws, the most important of them being that many good analogical arguments would be deemed bad or deficient. Additionally, Shecaira misrepresents my alternative account as something in between deductivism and non-deductivism. This paper is both an attempt at solving this misunderstanding and an analysis and criticism of Waller and Shecaira’s forms of deductivism.

The paper provides a qualified defence of Bruce Waller’s deductivist schema for a priori analogical arguments in ethics and law. One crucial qualification is that the schema represents analogical arguments as complexes composed of one deductive inference but also of one non-deductive subargument. Another important qualification is that the schema is informed by normative assumptions regarding the conditions that an analogical argument must satisfy in order for it to count as an optimal instance of its (...) kind. Waller’s schema is defended from criticisms formulated by Trudy Govier, Marcello Guarini and Lilian Bermejo-Luque. (shrink)

Following a Toulmian account of argument analysis and evaluation, I offer a general unitary schema for, so called, deductive and inductive types of analogical arguments. This schema is able to explain why certain analogical arguments can be said to be deductive, and yet, also defeasible.

In this paper I will argue that most objections to deductive analyses of a priori analogies are incorrect, often involve basic misinterpretations of what the deductive reconstruction of those arguments are saying, and sometimes also betray a confusion about what part of the reasoning corresponds to the analogical inference. In particular, I will be focusing on a raft of objections made by Juthe in [2015] and subject his alternative views to criticism. -/- I will then argue that Juthe (...) does implicitly have a good argument against deductivism: adding further analogues seems to have a cumulative force that they would not have on a deductivist analysis. This is so not only in ordinary analogical arguments but, perhaps surprisingly, with a priori analogical arguments. I will then argue that this does not favor a sui generis view of the analogical argument over inductivist views, and attempt to show that a confirmation-theoretic approach to analogical inference makes the best sense of our intuitions about the strength of analogical arguments.

This book presents adaptive logics as an intuitive and powerful framework for modeling defeasible reasoning. It examines various contexts in which defeasible reasoning is useful and offers a compact introduction into adaptive logics. The author first familiarizes readers with defeasible reasoning, the adaptive logics framework, combinations of adaptive logics, and a range of useful meta-theoretic properties. He then offers a systematic study of adaptive logics based on various applications. The book presents formal models for defeasible reasoning stemming from different contexts, (...) such as default reasoning, argumentation, and normative reasoning. It highlights various meta-theoretic advantages of adaptive logics over other logics or logical frameworks that model defeasible reasoning. In this way the book substantiates the status of adaptive logics as a generic formal framework for defeasible reasoning. (shrink)

Elqayam & Evans (E&E) drive a wedge between Bayesianism and instrumental rationality that most decision scientists will not recognize. Their analogy from linguistics to judgment and decision making is inapt. Normative models remain extremely useful in the progressive research programs of the judgment and decision making field.

The purpose of this paper is to analyze the structure and the defeasibility conditions of argument from analogy, addressing the issues of determining the nature of the comparison underlying the analogy and the types of inferences justifying the conclusion. In the dialectical tradition, different forms of similarity were distinguished and related to the possible inferences that can be drawn from them. The kinds of similarity can be divided into four categories, depending on whether they represent fundamental semantic features of (...) the terms of the comparison or non-semantic ones, indicating possible characteristics of the referents. Such distinct types of similarity characterize different kinds of analogical arguments, all based on a similar general structure, in which a common genus is abstracted. Depending on the nature of the abstracted common feature, different rules of inference will apply, guaranteeing the attribution of the analogical predicate to the genus and to the primary subject. This analysis of similarity and the relationship thereof with the rules of inference allows a deeper investigation of the defeasibility conditions. (shrink)

In a priori analogies, the analogue is constructed in imagination, sharing certain properties with the primary subject. The analogue has some further property clearly consequent on those shared properties. Ceteris paribus the primary subject has that property also. The warrant involves non-empirical, e.g., moral intuition but is also defeasible. The argument is thus neither deductive nor inductive, but an additional type. In an inductive analogy, the analogues back the warrant from below. Distinguishing these two types of arguments by analogy (...) gives epistemic evaluative factors primacy over resemblance factors in classifying arguments—a prescient insight on Govier’s part.

This paper addresses several issues in argumentation theory. The over-arching goal is to discuss how a theory of analogical argument schemes fits the pragma-dialectical theory of argument schemes and argument structures, and how one should properly reconstruct both single and complex argumentation by analogy. I also propose a unified model that explains how formal valid deductive argumentation relates to argument schemes in general and to analogical argument schemes in particular. The model suggests “scheme-specific-validity” i.e. that there are contrasting (...) species of validity for each type of argument scheme that derive from one generic conception of validity. (shrink)

This paper argues that some traditional fallacies should be considered as reasonable arguments when used as part of a properly conducted dialog. It is shown that argumentation schemes, formal dialog models, and profiles of dialog are useful tools for studying properties of defeasible reasoning and fallacies. It is explained how defeasible reasoning of the most common sort can deteriorate into fallacious argumentation in some instances. Conditions are formulated that can be used as normative tools to judge whether a given (...) defeasible argument is fallacious or not. It is shown that three leading violations of proper dialog standards for defeasible reasoning necessary to see how fallacies work are: (a) improper failure to retract a commitment, (b) failure of openness to defeat, and (c) illicit reversal of burden of proof.

This paper proposes an approach to investigate norm-governed learning agents which combines a logic-based formalism with an equation-based counterpart. This dual formalism enables us to describe the reasoning of such agents and their interactions using argumentation, and, at the same time, to capture systemic features using equations. The approach is applied to norm emergence and internalisation in systems of learning agents. The logical formalism is rooted into a probabilistic defeasible logic instantiating Dung’s argumentation framework. Rules of this logic are attached (...) with probabilities to describe the agents’ minds and behaviours as well as uncertain environments. Then, the equation-based model for reinforcement learning, defined over this probability distribution, allows agents to adapt to their environment and self-organise. (shrink)

Many of the most influential theorists of linguistic justice make arguments on the basis of comparisons between language and religion. They claim either that (1) language, by contrast with religion, cannot be separated from the state or that (2) unequal official linguistic recognition, just like unequal official religious recognition, is morally problematic. This article argues that careful attention to debates about liberalism and the place of religion in public life invites us to question the two above-mentioned liberal assumptions (...) about religion underlying many arguments concerning linguistic justice based on (dis)analogies between language and religion. The hope is that such critical scrutiny is likely to shed some light on normative questions of linguistic justice, more precisely on questions about the legitimacy of granting more recognition to certain languages, usually those of national native groups (as opposed to groups resulting from more or less recent immigration).

This paper defends the normativity of meaning thesis by clearing up a misunderstanding about what the thesis amounts to. The misunderstanding is that according to it, failing to use an expression in accordance with the norms which constitute its meaning amounts to changing the expression’s meaning. If this was what the thesis claimed, then it would indeed be easy to show that meaning norms do not yield prescriptions and cannot be followed. However, there is another reading: what is constitutive of (...) meaning is not the norm’s being followed, but the norm’s being applicable. On this reading, some standard arguments against the thesis lose their force. After discussing the alternative reading and its consequences, the paper goes on to sketch a model of how norms of meaning become applicable in the first place. This model supports the view that talk of meaning has its pragmatic home in contexts of linguistic calibration. (shrink)

This paper argues that Donald Davidson’s infamous denial in “A Nice Derangement of Epitaphs” that there is any such thing as a language, though it may not be fully supported by the arguments given for it in that paper, is nonetheless entailed by his semantic views generally, according to which the literal, linguistic meaning of a speaker’s words on an occasion is determined by how the speaker intended to be understood. In favor of this view, and thus against conventional (...) languages, the paper then argues that this understanding of linguistic meaning promises, in a way the conventional view of meaning does not, to make sense of linguistic normativity.

In this article I introduce constitutive norm accounts of assertion, and then give three arguments for giving up on the constitutive norm project. First I begin with an updated version of MacFarlane’s Boogling argument. My second argument is that the ‘overriding response’ that constitutive norm theorists offer to putative counterexamples is unpersuasive and dialectically risky. Third and finally, I suggest that constitutive norm theorists, in appealing to the analogy of games, actually undermine their case that they can make sense of (...) assertions that fail to follow their putative constitutive norm. These considerations, I suggest, together show that the constitutive norm project founders not because any single norm is not descriptively correct of our assertion practices, but rather, because giving a constitutive norm as the definition of assertion alone is insufficient.

Cross-cultural differences in argumentation may be explained by the use of different norms of reasoning. However, some norms derive from, presumably universal, mathematical laws. This inconsistency can be resolved, by considering that some norms of argumentation, like Bayes theorem, are mathematical functions. Systematic variation in the inputs may produce culture-dependent inductive biases although the function remains invariant. This hypothesis was tested by fitting a Bayesian model to data on informal argumentation from Turkish and English cultures, which linguistically mark evidence quality (...) differently. The experiment varied evidential marking and informant reliability in argumentative dialogues and revealed cross-cultural differences for both independent variables. The Bayesian model fitted the data from both cultures well but there were differences in the parameters consistent with culture-specific inductive biases. These findings are related to current controversies over the universality of the norms of reasoning and the role of normative theories in the psychology of reasoning. (shrink)

For Kant and his followers, pure reason can be practical, and its substantive practical command is, broadly speaking, that we treat ourselves and others as worthy of respect as free and equal. If those who have defended the Kantian morality system are correct, this moral imperative will not be authoritative and inescapable simply because we don't know how to coherently reweave our practical commitments so as to leave it out, but because it is presupposed by the possibility of practical reason. (...) On this model, the rational authority of moral dictates would be understood as absolute and universal. ;But what if Kant and his followers have been wrong? What if the search for practical unconditionality turned out to be vain? Kant himself would most likely react to this news by pronouncing that, without a priori necessity, there could be no moral necessity, and without moral necessity, there could be no purity of motive, and without purity of motive, there could be no moral worth, and without moral worth, there could be no legitimate ascriptions of praise and blame. In short, for Kant and his orthodox followers, without unconditionality, the morality system would collapse. ;I will argue that the search for a priori necessity behind moral law is indeed hopeless, but that this does not entail the collapse of the morality system. It does however force us to conceive a new way of accounting for practical normativity in the absence of unconditionality. It also requires that, in order to preserve morality, we find a defensible place for it as a contingent subset of ethics broadly construed. My answer is to provide a new account of morality, and practical normativity in general, against the backdrop of neopragmatism. My hope is to provide an alternative story which preserves the Kantian insight that practical necessity is driven by rational authority, but which does not presuppose unconditionality to explain the latter's force and inescapability. In short I will attempt to show that ethical principles, when considered in linguistic space, need not be a priori necessary to bind individuals in a genuinely authoritative sense. (shrink)

In this paper I provide some linguistic evidence to the thesis that responsibility judgments are normative. I present an argument from negation, since the negation of descrip- tive judgments is structurally different from the negation of normative judgments. In particular, the negation of responsibility judgments seem to conform to the pattern of the negation of normative judgments, thus being a prima facie evidence for the normativity of responsibility judgments. I assume — for the argument’s sake — (...) Austin’s distinction be- tween justification and excuse, and I sketch how to accommodate the distinction between internal (justification) and external (excuse) nega- tion of responsibility within a language with a second-order analogous of existential generalization and λ operator. In the end I confront with and refute some objections against this argument. (shrink)

"Dissertation Advisor: Richard Cobb-Stevens Second Reader: David Rasmussen -/- My overall concern is with the Kantian legacy in political thought. More specifically, I want to know if normative talk is still viable in the wake of Wittgenstein and the linguistic turn; and if so, in what form. Most commentators today believe we have to choose between these two thinkers, either sacrificing a real concern with normativity (“relativism”) or a convincing engagement with our ordinary language (“universalism”). I follow Hilary (...) Putnam in thinking we do not have to choose between these rather drastic construals. It might still be possible to defend the force and relevance of normative exchange while still being alive to the drift of ordinary communication. This middle stance is best exemplified, I believe, by what I have called normative evaluation. -/- Basically, I am building on and extending insights and styles of argumentation that Putnam has pioneered over the years. The universalist’s rigid dichotomies (norms vs. values, rules vs. attitudes, thick vs. thin ethical concepts, justice vs. the good life, etc.) all fail the test of ordinary language. As Putnam has also shown, however, we do rely on paired concepts like these and they might still be argued to be strong—rational—enough to justify making *relative distinctions*. A relative distinction between values and norms is decisive, I think, because it would put us in the position to talk meaningfully about and reasonable settle what is more proper to one particular individual, group, or society from what is less so, thereby also making possible a normative exchange *between* them. I am therefore taking Putnam as pointing out a way to preserve key Kantian insights about the irreducibility and ubiquity of the normative while discarding his transcendental wrapping, all the while avoiding the kind of slide to wholesale cultural relativism that so easily follows in the wake of standard critiques of Kant. -/- Chapter 1: General survey.

Domain constraint, the requirement that analogues be selected from "the same category," inheres in the popular saying "you can't compare apples and oranges" and the textbook principle "the greater the number of shared properties, the stronger the argument from analogy." I identify roles of domains in biological, linguistic, and legal analogy, supporting the account of law with a computer word search of judicial decisions. I argue that the category treatments within these disciplines cannot be exported to general informal logic, (...) where the relevance of properties, not their number, must be the logically prior criterion for evaluating analogical arguments.

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.

Individualists and externalists about language take themselves to be disagreeing about the basic subject matter of the study of language. Are linguistic facts are really facts about individuals, or really facts about language use in a community?The right answer to this question, I argue, is ‘Yes’. Both individualistic and social facts are crucial to a complete understanding of human language. The relationship between the theories inspired by these facts is analogous to the relationship between anatomy and ecology, or between (...) micro- and macro-economics: both types of facts are important objects of study in their own right, but we need a theory that accounts for the complex relationship between the two. I argue that modern extensions of the signaling-games approach of Lewis (1969) do just this, defusing the conflict while preserving the core positive insights of both sides of this debate.The upshot is that arguments for social externalism and the normativity of meaning pose no threat to individualist explanations and can be accountedfor within a naturalistic theory of language. A good externalist theory will make crucial reference to individualistic facts, but go further by examining language users’ interactions in a systematic way. (shrink)

Walton's book is a study of several fallacies in informal logic. Focusing on question-answer dialogues, and committed to a pragmatic rather than a semantic approach, he attempts to generate criteria for evaluating good and bad questions and answers. The book contains a discussion of such well-recognized fallacies as many questions, black-or-white questions, loaded questions, circular arguments, question-begging assertions and epithets, ad hominem and tu quoque arguments, ignoratio elenchi, and replying to a question with a question. In addition, Walton develops several (...) artificial dialogue games and has an excellent discussion of burden of proof in nonlegal contexts. The discussion is for the most part nontechnical and does not presuppose any training in formal logic. It is illustrated with many (sometimes overlong) examples of fallacies drawn from real life--mostly debates in the Canadian House of Commons. . . . Walton's book breaks new ground on a number of issues. Choice This first full-length study of logical fallacies, errors, faults, illicit attacks, blunders, and other critical deficiencies in interrogation and reply has been written in the tradition of informal fallacies in logic. It is especially valuable, readable, and interesting because of the 139 case studies it presents, many of these case studies come from political debates and some from interviews, legal cross-examinations, and other sources. Walton uses these challenging examples of tricky, aggressive, argumentative, or fallacious questions to develop coherent and pragmatic guidelines for criticizing questionable questions (and in some cases their replies) on logical grounds. Among the types of problematic questions analyzed are: the traditional so-called fallacy of many questions, illustrated by the famous Have you stopped beating your wife?; black and white questions; terminologically loaded questions; and questions containing personal attacks. These and other types of problematic questions as well as evasive replies and replying to a question with a question are studied. Critical errors of reasoning are identified and analyzed by developing context-based, normative models of reasonable dialogue in which a questioner must have freedom to ask informative and probing questions, and the respondent must be constrained to give reasonably direct, not overly evasive answers. In this era of negative and evasive political campaigning, with candidates employing skillful tactics of manipulating public opinion to assure election rather than taking clear stands and seriously debating issues in an informed and sincere manner, Question-Reply Argumentation is especially relevant reading for those who take democracy seriously. The methods used reflect a significant shift from earlier semantically based theories to current pragmatic, dialogue-based models, and will be of interest to logicians and linguists. The volume's conclusions should challenge some current preconceptions. Recommended reading for courses in logic, speech communications, linguistics, philosophy of language, areas of political science relating to political discourse and debate, courses on questioning in cognitive psychology, and courses on critical thinking in education.

This paper analyses the logical structure of the balancing of conflicting normative arguments, and asks whether non-monotonic logic is adequate to represent this type of legal or practical reasoning. Norm conflicts are often regarded as a field of application for non-monotonic logics. This paper argues, however, that the balancing of normative arguments consists of an act of judgement, not a logical inference, and that models of deductive as well as of defeasible reasoning do not give an adequate account (...) of its structure. Moreover, it argues that as far as the argumentation consists in logical inferences, deductive logic suffices for reconstructing the argumentation from the internal point of view of someone making normative judgements.

Argumentation schemes are forms of reasoning that are fallible but correctable within a self-correcting framework. Their use provides a basis for taking rational action or for reasonably accepting a conclusion as a tentative hypothesis, but they are not deductively valid. We argue that teleological reasoning can provide the basis for justifying the use of argument schemes both in monological and dialogical reasoning. We consider how such a teleological justification, besides being inspired by the aim of directing a bounded cognizer to (...) true belief and correct choices, needs to take into account the attitudes of dialogue partners as well as normative models of dialogue and communicative activity types, in particular social and cultural settings. (shrink)

In this paper, we use concepts, structure and tools from argumentation theory to show how conversational implicatures are triggered by conflicts of presumptions. Presumptive implicatures are shown to be based on defeasible forms of inference used in conditions of lack of knowledge, including analogical reasoning, inference to the best explanation, practical reasoning, appeal to pity, and argument from cause. Such inferences are modelled as communicative strategies to knowledge gaps that shift the burden of providing the missing contrary evidence to (...) the other party in a dialogue. Through a series of illustrative examples, we show how such principles of inference are based on common knowledge about the ordinary course of events shared by participants in a structured dialogue setting in which they take turns putting forward and responding to speech acts.

One major facilitator of analogical reasoning is conceptual metaphor: cross-domain mappings that preserve relations and thereby motivate the extension of linguistic terms from the source to the target domain. Their conscious and explicit use in analogical reasoning has been helpful and productive in disciplines ranging from physics to psychology, and philosophy. At the same time, students of metaphor have suggested that partially unwitting use of conceptual metaphors led to unsound but intuitive conceptions of the mind, in philosophy (...) and psychology. This paper develops an explanation of some highly influential intuitions from the philosophy of mind, which helps answer the resulting question: When and why does the frequently helpful use of metaphors in analogical reasoning turn pernicious? In response, the paper brings together two hitherto largely distinct strands of research from cognitive psychology, in a case-study on the philosophy of mind: The paper uses structure-mapping theory to explain how simple analogical reasoning generates conceptual metaphors that facilitate more complex analogical reasoning, which is often non-intentional. Second, the paper examines how such reasoning interacts with partial-matching effects in memory-based processing. Drawing on Budiu and Anderson’s model of “information-based processing”, the paper shows that this interaction leads to predictable fallacies. It brings out the relevance of such fallacies by showing that they shaped introspective conceptions of the mind that dominated philosophical discourse throughout early modernity and retain some cultural influence to this day. On this basis, the paper delineates when and where those fallacies are liable to occur. (shrink)

The essays that make up my dissertation share a methodological approach that aims to explore the philosophical implications of linguists' accounts of ordinary language use. In particular, all of them focus on epistemic natural language and the implications that linguists' accounts of such language has for epistemology. The first essay focuses on the debate about the norms that govern assertion and shows the ways in which research on natural language evidentiality has direct bearing. This essay uses existing cross-linguistic data (...) about assertions in Quechua and Cheyenne to argue that assertions and the norms that govern them are more complex than allowed for in extant views. What makes Quechua and Cheyenne important is that they allow speakers to assert sentences the content of which they do not believe, or even believe to be false, as long as the sentence contains the right evidential marker. This is a problem for the current theories as they all take belief in the proposition being expressed as a minimal requirement for a speaker to felicitously assert. Given the data, I argue that we should see evidential markers as modifying the norm that is in place governing felicity of the current content. I go on to present three implementations of a context-sensitive norm and argue that only the ones that are evidence-based or completely contextual can properly capture the entire set of linguistic data. In the second essay I argue that epistemic uses of 'should' can be modelling using the standard Kratzerian modal canon. In Kratzer's system, modals induce quantification over some partially ordered, restricted class of worlds. The relevant partially ordered, restricted class of worlds is generally fixed by two ingredients: a modal base and an ordering source. Modelling epistemic uses of 'should' requires us to rethink and expand what has traditionally been thought of as making up an epistemic modal base. Traditionally it has been thought that epistemic modal bases just include information about probabilities but this thought needs to be updated in order to bring epistemic 'should' into the fold. I argue that there are good theoretical reasons for having as uniform a semantics as possible then show that the context-sensitive semantic model that I develop meets all empirical demands. I end the essay by arguing that this updated way of thinking about epistemic modals bases has implications for epistemology. The final essay outlines the broad type of methodological approach mentioned above that guides the research throughout the dissertation. In it, I argue that the results of linguistics' theorizing about semantics, especially within the epistemic domain, ought to be seen as an accurate guide to reality. Looking to the way that language evolves over time and what it takes for information to become encoded into language is what drives this result. Buttressing the evolutionary explanation with results from the Condorcet Jury Theorem gives us more reason to believe that language is an accurate, albeit defeasible, guide to reality. If these results hold, they not only have broad implications for how we ought to be conducting our epistemological theorizing but our philosophical theorizing in general. (shrink)

In a recent paper, Paul Coates defends a sophisticated dispositional account which allegedly resolves the sceptical paradox developed by Kripke in his monograph on Wittgenstein's treatment of following a rule (Kripke, 1982). Coates' account appeals to a notion of 'homeostasis', unpacked as a subject's second-order disposition to maintain a consistent pattern of extended first-order dispositions regarding her linguistic behavior. This kind of account, Coates contends, provides a naturalistic model for the normativity of intentional properties and thus resolves Kripke's sceptical (...) paradox. In this paper I argue that Coates' second-order dispositional account cannot solve the sceptic's problems regarding meaning and normativity. My main contention is that in order for second-order dispositions to be able to effectively regulate the coordinated responses constitutive of first-order dispositions, those first order dispositions must be independently identifiable. Yet that's precisely what Kripke's sceptical argument calls into question. I shall also argue, in a more positive fashion, that Coates' own appeal to practical breakdowns may suggest a different —and more effective— response to the sceptic's concern. (shrink)

Building upon work by Mary Hesse (1974), this paper aims to show that a single method of investigation lies behind Maxwell’s use of physical analogies in his major scientific works before the Treatise on Electricity and Magnetism. Key to understanding the operation of this method is to recognize that Maxwell’s physical analogies are intended to possess an ‘inductive’ function in addition to an ‘illustrative’ one. That is to say, they not only serve to clarify the equations proposed for an unfamiliar (...) domain with a working interpretation drawn from a more familiar science, but can also be sources of defeasible yet relatively strong arguments from features of the more familiar domain to features of the less. Compared with the reconstructions by Achinstein (1991), Siegel (1991), Harman (1998) and others, which postulate a discontinuity in Maxwell’s approach to physical analogy, the account defended in this paper i) makes sense of the continuity in Maxwell’s remarks on scientific methodology, ii) explains his quest for a “mathematical classification of physical quantities” and iii) offers a new and more plausible interpretation of the debated episode of the introduction of the displacement current in Maxwell’s “On Physical Lines of Forces”.

New medical technologies provide us with new possibilities in health care and health care research. Depending on their degree of novelty, they may as well present us with a whole range of unforeseen normative challenges. Partly, this is due to a lack of appropriate norms to perceive and handle new technologies. This article investigates our ways of establishing such norms. We argue that in this respect analogies have at least two normative functions: they inform both our understanding and (...) our conduct. Furthermore, as these functions are intertwined and can blur moral debates, a functional investigation of analogies can be a fruitful part of ethical analysis. We argue that although analogies can be conservative; because they bring old concepts to bear upon new ones, there are at least three ways in which they can be creative. First, understandings of new technologies are quite different from the analogies that established them, and come to be analogies themselves. That is, the concepts may turn out to be quite different from the analogies that established them. Second, analogies transpose similarities from one area into another, where they previously had no bearing. Third, analogies tend to have a figurative function, bringing in something new and different from the content of the analogies. We use research-biobanking as a practical example in our investigations. (shrink)

This game3 was designed to investigate protocols and strategies for resourcebounded disputation. The rules presented here correspond very closely to the problem of controlling search in an actual program. The computer program on which the game is based is LMNOP. It is a LISP system designed to produce arguments and counterarguments from a set of statutory rules and a corpus of precedents, and applied to legal and quasi-legal reasoning. LMNOP was co-designed by a researcher in AI knowledge representation and by (...) a trained computer scientist who was an editor of Washington University Law Review at the time. LMNOP is based on the idea of a non-demonstrative or defeasible rule: i.e., a rule that admits exceptions. It adopts a representational convention that supposes there is an implicit preference of more specific rules over less specific rules. In fact, it automatically adjudicates between competing arguments when one argument meets the broader criterion of being more specific than another. The convention is based on an idea origianlly presented by David Poole [85], and is embedded in a system of determining which arguments are ultimately warranted, which originally appeared in the literatures of epistemology and ethics, by Pollock [87]. This system evolves from work by the first author since 1987; the full statement of the theory is in [92]. Prakken [92] is one example of the idea’s application to the legal domain. LMNOP also draws heavily on the model of legal reasoning and analogical reasoning put forward by Edwina Rissland and Kevin Ashley [89, 90]. Similarities to their legal casebased reasoning program, HYPO, are no accident; LMNOP seeks to improve on HYPO. A description of LMNOP is forthcoming. (shrink)

This is the first installment of a two-part essay. Limitations of space prevented the publication of the full essay in present issue of the Journal. The second installment will appear in the next issue, 2021 (1). My overall goal is to outline a strategy for integrating generative linguistics with a broadly pragmatist approach to meaning and communication. Two immensely useful guides in this venture are Robert Brandom and Paul Pietroski. Squarely in the Chomskyan tradition, Pietroski’s recent book, Conjoining Meanings, offers (...) an approach to natural-language semantics that rejects foundational assumptions widely held amongst philosophers and linguists. In particular, he argues against extensionalism—the view that meanings are (or determine) truth and satisfaction conditions. Having arrived at the same conclusion by way of Brandom’s defl ationist account of truth and reference, I’ll argue that both theorists have important contributions to make to a broader anti-extensionalist approach to language. What appears here as Part 1 of the essay is largely exegetical, laying out what I see as the core aspects of Brandom’s normative inferentialism (§1) and Pietroski’s naturalistic semantics (§2). In Part 2 (next issue), I argue that there are many convergences between these two theoretical frameworks and, contrary to first appearances, very few points of substantive disagreement between them. If the integration strategy that I propose is correct, then what appear to be sharply contrasting commitments are better seen as interrelated verbal differences that come down to different—but complementary—explanatory goals. The residual disputes are, however, stubborn. I end by discussing how to square Pietroski’s commitment to predicativism with Brandom’s argument that a predicativist language is in principle incapable of expressing ordinary conditionals.

Political theorists frequently utilize the ‘firm–state analogy’ (FSA) to support the arguments for democratic governance in firms. This article presents the FSA as an analogy with both justificatory and epistemic functions. Its justificatory function provides valid justificatory strategies for workplace democracy, while its epistemic function offers models that shape the understanding of corporate power. In this article, four limitations of the justificatory function of the FSA are identified: (i) the problem of ambiguity, (ii) the boundary problem, (iii) the issue of (...) normative redundancy, and (iv) the universality problem. Furthermore, the article argues that the epistemic function of the FSA fails to adequately address some of the most concerning forms of corporate power wielded by large, particularly multinational, corporations in the realm of international trade. As a result, the FSA misses crucial reasons for the normative desirability of democracy in corporate governance. (shrink)

The paper discusses the notion of defeasibility and focuses specifically on defeasible norms. First, it delineates a robust notion of the phenomenon of defeasibility, which poses a serious problem for both moral and legal theory. It does this by laying out the conditions and desiderata that a model of defeasibility should be able to meet. It further focuses on a specific model of defeasibility that utilises the notion of normal conditions to expound the robust notion of (...) defeasibility. It argues that this model fails in its attempt to do this, particularly since it presupposes further pertinent norms and we have reasons to doubt if these are defeasible. It thus does not allow defeasibility to go “all the way down” in the normative domain and limits it merely to a feature of some sort of mid-level norm. In conclusion, it draws lessons from this and positions defeasibility models within a more general pluralistic approach to norms. (shrink)

Proof requires a dialogue between agents to clarify obscure inference steps, fill gaps, or reveal implicit assumptions in a purported proof. Hence, argumentation is an integral component of the discovery process for mathematical proofs. This work presents how argumentation theories can be applied to describe specific informal features in the development of proof-events. The concept of proof-event was coined by Goguen who described mathematical proof as a public social event that takes place in space and time. This new meta-methodological concept (...) is designed to cover not only “traditional” formal proofs but all kinds of proofs and inference steps, including incomplete or purported proofs. Our approach attempts to make proof-events more comprehensive to express the complete trajectory of a mathematical proof-event until the ultimate validation of the proving outcome. Thus, we advance an extended version of proof-event calculus which is built on argumentation theories designed to capture the internal and external structure of collaborative mathematical practice and highlight the relationship between proof, human reasoning, and cognitive processes. In addition, another area in which argumentation can make a significant contribution is dealing with the defeasible knowledge of the Web which is a product of its open and ubiquitous nature. This approach seems to be sufficient for the presentation of Web-based proving processes as manifested in the case of the Mini-Polymath 4 project. (shrink)

Accounts of analogical inference are usually categorized into four broad groups: abductive, deductive, inductive and sui generis. The purpose of this paper is to defend a sui generis model of analogical inference. It focuses on the sui generis account, as developed by Juthe [2005, 2009, 2015, 2016] and Botting’s [2017] criticism of it. This paper uses the pragmadialectical theory of argumentation as the methodological framework for analyzing and reconstructing argumentation. The paper has two main points. First, that Juthe’s (...) arguments against a deductive interpretation of prima facie analogy argumentation remain unaffected by Botting’s criticism, which means that many of the reasons against deductive reformulation of analogy argumentation still stand. The additional argument, which Botting himself brings up, that a deductive interpretation cannot account for the cumulative effect of analogies, just provides further reason to reject deductivism. The second main point of this paper is that an inductive interpretation of analogical inference also fails. There are constitutional differences between inductive and analogical inference that cannot be bridged. The result is a firm defense of the sui generis view of analogical inference. (shrink)

Arguments from analogy are pervasive in everyday reasoning, mathematics, philosophy, and science. Informal logic studies everyday argumentation in ordinary language. A branch of fuzzy logic, approximate reasoning, seeks to model facets of everyday reasoning with vague concepts in ill-defined situations. Ways of combining the results from these fields will be suggested by introducing a new argumentation scheme—a fuzzy analogical argument from classification—with the associated critical questions. This will be motivated by a case study of analogical reasoning in the (...) virtual friendship debate within information ethics. The virtual friendship debate is a disagreement over whether virtual friendships are genuine friendships. It will be argued that the debate could move away from its current impasse, caused by unproductive metaphysical and logical assumptions, if extant arguments are reinterpreted as fuzzy analogical arguments from classification, and subjected to a new set of critical questions which would replace the quest for facts of essence about friendship with an emphasis on empirical data, persuasion, and definitional power.

This paper begins a working through of Blair’s (2001) theoretical agenda concerning argumentation schemes and their attendant critical questions, in which we propose a number of solutions to some outstanding theoretical issues. We consider the classification of schemes, their ultimate nature, their role in argument reconstruction, their foundation as normative categories of argument, and the evaluative role of critical questions.We demonstrate the role of schemes in argument reconstruction, and defend a normative account of their nature against specific criticisms (...) due to Pinto (2001). Concerning critical questions, we propose an account on which they are founded in the R.S.A. cogency standard, and develop an account of the relationship between critical questions and burden of proof. Our ultimate aim is to initiate a reconciliation between dialectical and informal logic approaches to the schemes. (shrink)

ABSTRACT Inspired by legal reasoning, this paper presents a semantics and proof theory of a system for defeasible argumentation. Arguments are expressed in a logic-programming language with both weak and strong negation, conflicts between arguments are decided with the help of priorities on the rules. An important feature of the system is that these priorities are not fixed, but are themselves defeasibly derived as conclusions within the system. Thus debates on the choice between conflicting arguments can also be modelled. The (...) semantics of the system is given with a fixpoint definition, while its proof theory is stated in dialectical style, where a proof takes the form of a dialogue between a proponent and an opponent of an argument: an argument is shown to be justified if the proponent can make the opponent run out of moves in whatever way the opponent attacks.

ABSTRACT In this paper, I analyse Rahel Jaeggi’s socio-ontological account of forms of life. I show that her framework is a two-sided one, since it involves an understanding of forms of life both as inert bundles of practices and as having a normative structure. Here I argue that this approach is based on an a priori argument which assumes normativity as the condition of intelligibility of social criticism. I show that the intimate tension between these two sides is (...) reflected in the socio-ontological model of the constitution of social phenomena, which on the one side is understood in terms of habituation and materialization, and on the other side in terms of constitution through norms. The second side in the end prevails and leads to some sort of normative essentialism which involves a prescriptive meta-theoretical understanding of normativity combined with a socio-ontological model of constitutive rules. I then analyse two arguments that Jaeggi offers in support of her assumption that normative constitution is the deep structure of social practices. I name these the functional-teleological argument, and the crisis developmental argument, and argue that neither succeeds in proving that practices are not normatively underdetermined. (shrink)

Deductivism is not merely a logical technique, but also a theory of normativity: it provides an objective and universal standard of evaluation. Contemporary dialectical logic rejects deductive normativity, replacing its universal standard by an intersubjective standard. It is argued in this paper that dialectical normativity does not improve upon deductive normativity. A dialogico-rhetorical alternative is proposed.

In lieu of an abstract, here is a brief excerpt of the content:Aesthetics and Humean Aesthetic Norms in the Novels of Jane AustenEva M. Dadlez (bio)IntroductionThe eighteenth century, Paul Oskar Kristeller tells us, in addition to crystallizing what we now call the fine arts, is also marked by an increased lay interest both in the arts and in criticism.1 Amateurs as well as philosophers ventured critical commentary on the arts. Talk concerning taste or beauty or the sublime was so much (...) a part of general discourse that even novelists of that era incorporated such subjects in their work. Henry Fielding "was able to construct a novel on the true and false sublime in art," according to Samuel Monk, "and to draw an analogy between the sublime in art and the sublime in character."2 So we shouldn't find it surprising that perspectives on aesthetics are sometimes presented in the novels of Jane Austen.3 This subject matter ranges from descriptions of skill in the execution and sensitivity in the appreciation of particular arts to general observations about beauty and taste and what is requisite for the apprehension of the former and the possession of the latter.Consider the following catalog of arts and beauties. Mansfield Park, Sense and Sensibility, and Northanger Abbey contain many references to the beauties of nature, both cultivated and wild. Taste in music is a topic in Persuasion, Mansfield Park, Pride and Prejudice, and Lady Susan. A taste for poetry and literature is the lot of the heroines of Persuasion, Northanger Abbey, Mansfield Park, and Sense and Sensibility. Taste and talent for drawing is exhibited by characters in Sense and Sensibility, Emma, and Northanger Abbey. Both Sense and Sensibility and Mansfield Park contain discussions of the merits of effective reading, that is, reading well aloud. Mansfield Park even comments on [End Page 46] acting ability, albeit rather disapprovingly. More general reflections on taste and beauty, as well as their connection to morality, are equally typical.It is possible to venture several different arguments about the philosophical perspective into which such observations best fit. Kantian analyses have already been ventured in the literature. Anne Crippen Ruderman calls our attention to the Kantian flavor of the connection Austen draws between a sensitivity to natural beauty and one's moral disposition, for instance, and David Kaufman compares Austen to Kant, though primarily in regard to ethics.4 Nonetheless, in this article I will argue that the strongest correlations and correspondences are in fact between Austen's and Hume's positions on aesthetics. Evidence in support of a Kantian analysis will first be canvassed and later compared with claims in favor of a Humean alternative.I will establish that the positions on taste and beauty and delicacy that are explicitly stated in or can be inferred from Austen's novels fit a Humean model—and fit it with a fair degree of precision. In doing so, I hope to demonstrate a correspondence strong enough to serve as the staging area for the further speculations that constitute the second thesis of this article. A great deal has already been said by philosophers about the capacity of literature to elicit moral reactions from the reader. Fictions can present ethical endorsements and invite us to adopt ethical perspectives by making it true in the world of the work that some course of action is right or some character is laudable. They can do this not by telling us that an act is right or a person meritorious but by showing us the rightness of the action and the commendability of the individual—by asking us to imagine traits that call forth our own approval and commendation. I will contend that aesthetic norms can be treated in much the same way as moral norms. That is, I will claim that the fiction of Jane Austen, in addition to evidencing the conscription of a Humean aesthetic, so engages and educates us that we are led imaginatively to adopt certain aesthetic perspectives in the course of its contemplation: not just by being told what is aesthetically pleasing or commendable, but by being made to feel pleasure and to experience commendation; not just by being told what constitutes discriminating taste, but by being led...

In the “Second Analogy,” Kant argues that, unless mental contents involve the concept of causation, they cannot represent an objective temporal sequence. According to Kant, deploying the concept of causation renders a certain temporal ordering of representations necessary, thus enabling objective representational purport. One exegetical question that remains controversial is this: how, and in what sense, does deploying the concept of cause render a certain ordering of representations necessary? I argue that this necessitation is a matter of epistemic normativity: with (...) certain causal presuppositions in place, the individual is obliged to make a judgment with certain temporal contents, on pain of irrationality. To make this normatively obligatory judgment, the subject must place her perceptual representations in a certain order. This interpretation fits Kant's text, his argumentative aims, and his broader views about causal inference, better than rival interpretations can. This result has important consequences for the ongoing debate over the role of normativity in Kant's philosophy of mind. (shrink)

This contribution aims at providing an argumentative method to account for epistemic modality and evidentiality. I claim that these two linguistic categories can work as semantic components of defeasible argumentative schemes based on classification processes. This kind of approximate reasoning is, in fact, frequently indicated by appearance verbs which signal that the inferred standpoint is conceived by the speaker as uncertain due to the deceiving nature of perceptual data. Drawing from an analysis at the semantic-argumentative interface, the way in (...) which prototype theory sheds light on the processes of meaning construction underlying defeasible arguments from definition is also shown.

The philosophy of linguistics is a rich philosophical domain which encompasses various disciplines. One of the aims of this thesis is to unite theoretical linguistics, the philosophy of language, the philosophy of science and the ontology of language. Each part of the research presented here targets separate but related goals with the unified aim of bringing greater clarity to the foundations of linguistics from a philosophical perspective. Part I is devoted to the methodology of linguistics in terms of scientific modelling. (...) I argue against both the Conceptualist and Platonist interpretations of linguistic theory by means of three grades of mathematical involvement for linguistic grammars. Part II explores the specific models of syntactic and semantics by an analogy with the harder sciences. In Part III, I develop a novel account of linguistic ontology and in the process comment on the type-token distinction, the role and connection with mathematics and the nature of linguistic objects. In this research, I offer a structural realist interpretation of linguistic methodology with a nuanced structuralist picture for its ontology. This proposal is informed by historical and current work in theoretical linguistics as well as philosophical views on ontology, scientific modelling and mathematics. (shrink)

Saul Kripke’s paradoxical argument in Wittgenstein on Rules and Private Language (1982) has generated an extravagant number of responses. A major debate prompted by this book has focused on the plausibility and role of the supposed normative character of meaning; the argument itself is often taken to rely on the assumption that meaning is irreducibly normative. Following Boghossian (1989), the normativity of meaning has been understood as closely tied to the existence of semantic correctness conditions. After a brief (...) introduction to the background of the debate, this work will focus on whether the normativity of meaning may be better understood as stemming from a different type of correctness, namely linguistic correctness. Linguistic correctness differs from semantic correctness insofar as it is related to conventional, and not truth-functional, meaning. I will begin by clarifying some of the features of linguistic correctness. First, I will outline some reasons why the distinction between linguistic and semantic correctness should be maintained. Then, I will anticipate a possible criticism and argue that linguistic correctness does not belong to the domain of pragmatics, as it is relevant to our understanding of conventional meaning. Finally, I will try to show that linguistic “oughts” are constitutive of meaning. Having established these basic features of linguistic correctness, I will investigate whether the fact that it is constitutive of meaning can vindicate the idea that meaning is robustly, irreducibly normative. By applying arguments from the realm of moral philosophy – within which, too, there have been attempts to show that constitutive facts can give rise to categorical moral norms – I will argue that linguistic correctness cannot give rise to categorical semantic norms. Linguistic correctness may be, nevertheless, a useful tool for explaining some of our intuitions about meaning. (shrink)

Il s'agit de déterminer le statut des normes chez les nouveaux casuistes . On indique d'abord quelles sont les circonstances de cette nouvelle casuistique ; on suggère ensuite qu'elle exporte dans le domaine de l'éthique certaines thèses de T. Kuhn, comme le « modèle déductiviste », qu'elle prétend détrôner, s'alimentait au schéma Hempel-Oppenheim de l'explication scientifique. On suggère enfin que les nouveaux casuistes procèdent, de façon plus ou moins radicale, à une naturalisation des normes.It is intented to investigate about the (...) status of norms in the thought of the new casuists . First, the circumstances of the new casuistry are set out; then it is suggested that the new casuists have integrated in their argument concepts from T. Kuhn, just as the “deductivist model” they so sharply criticize integrates concepts from C.G. Hempel and P. Oppenheim. With regard to the initial question, it is shown that the new casuists uphold a kind of norms-naturalizing constructivism. (shrink)

Argument by analogy has long been regarded as the characteristic way of arguing in ancient Chinese culture. Classic Chinese philosophers not only prefer to use analogy to argue for their own views, but also take efforts to theorize it in a systematic way. This paper aims to provide a careful study on the relevant ideas in ancient China in order to reconstruct the ancient Chinese theory of argument by analogy, and then to reveal some of its distinctive features through a (...) comparison with the Western counterpart account as developed by Aristotle. It is indicated that in ancient China analogical argument was conceived primarily as a way of arguing based on classification, with a unique mechanism of taking and giving according to kind. On that basis, it is argued that although such a characterization captures the logical structure of analogical argument in a similar way to Aristotle, the ancient Chinese theory stresses the foundational role of a particular notion of kind, thus makes the construction and application of analogical arguments become highly flexible and context-sensitive. Moreover, it is also contended that in ancient China the rationale of analogical arguments is explained from a general perspective of kind, relying upon the universal knowledge pertaining to the forming of kinds. Then it is further revealed that, unlike Aristotle who emphasizes the causal links between attributes in the physical world, ancient Chinese thinkers justify analogical argument by appealing to some normative metaphysical and epistemological principles.

As more and more sophisticated software is created to allow the mining of arguments from natural language texts, this paper sets out to examine the suitability of the well-established and readily available methods of corpus linguistics to the study of argumentation. After brief introductions to corpus linguistics and the concept of meta-argument, I describe three pilot-studies into the use of the terms Straw man, Ad hominem, and Slippery slope, made using the open access News on the Web corpus. The presence (...) of each of these phrases on internet news sites was investigated and assessed for correspondence to the norms of use by argumentation theorists. All three pilot-studies revealed interesting facts about the usage of the terms by non-specialists, and led to numerous examples of the types of arguments mentioned. This suggests such corpora may be of use in two different ways: firstly, the wider project of improving public debate and educating the populace in the skills of critical thinking can only be helped by a better understanding of the current state of knowledge of the technical terms and concepts of argumentation. Secondly, theorists could obtain a more accurate picture of how arguments are used, by whom, and to what reception, allowing claims on such matters to be evidence, rather than intuition, based.
