As Grice defined it, a speaker conversationally implicates that p only if the speaker expects the hearer to recognize that the speaker thinks that p. This paper argues that in the sorts of cases that Grice took as paradigmatic examples of conversational implicature there is in fact no need for the hearer to consider what the speaker might thus have in mind. Instead, the hearer might simply make an inference from what the speaker literally says and the situation (...) in which the utterance takes place. In addition, a number of sources of the illusion of conversational implicatures in Grice's sense are identified and diagnosed. (shrink)

This paper is about the pragmatic inferences in play as conversational implicatures (Grice, P. 1989. Studies in the way of words. Cambridge, MA: Harvard University Press) occur. First, it constructs the deductivism versus abductivism debate that transpires from the extant literature but is rarely elaborated. Against deductivism, the paper argues that implicating inferences in conversational implicatures can instantiate an abductive logical form, as abductivism suggests. Against abductivism, however, it grants to deductivism that implicating inferences can have a deductive (...) form provided the latter is of a defeasible type. In sum, it thus argues for pluralist defeasibilism. Second, it turns to the issue of the ontological nature of implicating inferences and advocates normative inferentialism, on which these inferences are not primarily real psychological processes but rules of the practice of implicating. While this allows for the possibility of their psychological instantiation, to be sure, the paper also insists that psychological inferring processes in implicatures are neither necessarily isomorphic to the aforementioned rules nor even necessarily occur as an implicature occurs.

In everyday conversations we often convey information that goes above and beyond what we strictly speaking say: exaggeration and irony are obvious examples. H.P. Grice introduced the technical notion of a conversational implicature in systematizing the phenomenon of meaning one thing by saying something else. In introducing the notion, Grice drew a line between what is said, which he understood as being closely related to the conventional meaning of the words uttered, and what is conversationally implicated, which can be (...) inferred from the fact that an utterance has been made in context. Since Grice’s seminal work, conversational implicatures have become one of the major research areas in pragmatics. This article introduces the notion of a conversational implicature, discusses some of the key issues that lie at the heart of the recent debate, and explicates tests that allow us to reliably distinguish between semantic entailments and conventional implicatures on the one hand and conversational implicatures on the other.

This fresh look at the philosophy of language focuses on the interface between a theory of literal meaning and pragmatics--a philosophical examination of the relationship between meaning and language use and its contexts. Here, Atlas develops the contrast between verbal ambiguity and verbal generality, works out a detailed theory of conversational inference using the work of Paul Grice on Implicature as a starting point, and gives an account of their interface as an example of the relationship between Chomsky's (...) Internalist Semantics and Language Performance. Atlas then discusses consequences of his theory of the Interface for the distinction between metaphorical and literal language, for Grice's account of meaning, for the Analytic/Synthetic distinction, for Meaning Holism, and for Formal Semantics of Natural Language. This book makes an important contribution to the philosophy of language and will appeal to philosophers, linguists, and cognitive scientists. (shrink)

In a series of experiments, Bott and Noveck (2004) found that the computation of scalar inferences, a variety of conversational implicature, caused a delay in response times. In order to determine what aspect of the inferential process that underlies scalar inferences caused this delay, we extended their paradigm to three other kinds of inferences: free choice inferences, conditional perfection, and exhaustivity in “it”‐clefts. In contrast to scalar inferences, the computation of these three kinds of inferences facilitated response times. Following (...) a suggestion made by Chemla and Bott (2014), we propose that the time it takes to compute a conversational implicature depends on the structural characteristics of the required alternatives.

How is human social intelligence engaged in the course of ordinary conversation? Standard models of conversation hold that language production and comprehension are guided by constant, rapid inferences about what other agents have in mind. However, the idea that mindreading is a pervasive feature of conversation is challenged by a large body of evidence suggesting that mental state attribution is slow and taxing, at least when it deals with propositional attitudes such as beliefs. Belief attributions involve contents that are decoupled (...) from our own primary representation of reality; handling these contents has come to be seen as the signature of full-blown human mindreading. However, mindreading in cooperative communication does not necessarily demand decoupling. We argue for a theoretical and empirical turn towards “factive” forms of mentalizing here. In factive mentalizing, we monitor what others do or do not know, without generating decoupled representations. We propose a model of the representational, cognitive, and interactive components of factive mentalizing, a model that aims to explain efficient real-time monitoring of epistemic states in conversation. After laying out this account, we articulate a more limited set of conversational functions for nonfactive forms of mentalizing, including contexts of meta-linguistic repair, deception, and argumentation. We conclude with suggestions for further research into the roles played by factive versus nonfactive forms of mentalizing in conversation. (shrink)

Throughout the Covid-19 pandemic, people have been eager to learn what factors, and especially what public health policies, cause infection rates to wax and wane. But figuring out conclusively what causes what is difficult in complex systems with nonlinear dynamics, such as pandemics. We review some of the challenges that scientists have faced in answering quantitative causal questions during the Covid-19 pandemic, and suggest that these challenges are a reason to augment the moral dimension of conversations about causal inference. (...) We take a lesson from Martha Nussbaum—who cautions us not to think we have just one question on our hands when we have at least two—and apply it to modeling for causal inference in the context of cost-benefit analysis.

The sentence "The boss fired the employee who is always late" invites the defeasible inference that the speaker is attempting to convey that the lateness caused the firing. We argue that such inferences cannot be understood in terms of familiar approaches to extrasemantic enrichment such as implicature, impliciture, explicature, or species of local enrichment already in the literature. Rather, we propose that they arise from more basic cognitive strategies, grounded in processes of coherence establishment, that thinkers use to make (...) sense of the world. Attention to such cases provides a richer and more varied landscape of extrasemantic enrichment than has been appreciated to date. (shrink)

When a speaker states an argument in arguing—in its core sense—for the conclusion, the speaker asserts, as opposed to merely implies or implicates, the associated inference claim to the effect that the conclusion follows from the premises. In defense of this, I argue that how an inference claim is conveyed when stating an argument is constrained by constitutive and normative conditions for core cases of the speech of arguing for a conclusion. The speech act of assertion better reflects (...) such conditions than does implication, conversational implicature, or conventional implicature. (shrink)

This monograph is an in-depth and engaging discourse on the deeply cognitive roots of human scientific quest. The process of making scientific inferences is continuous with the day-to-day inferential activity of individuals, and is predominantly inductive in nature. Inductive inference, which is fallible, exploratory, and open-ended, is of essential relevance in our incessant efforts at making sense of a complex and uncertain world around us, and covers a vast range of cognitive activities, among which scientific exploration constitutes the pinnacle. (...) Inductive inference has a personal aspect to it, being rooted in the cognitive unconscious of individuals, which has recently been found to be of paramount importance in a wide range of complex cognitive processes. One other major aspect of the process of inference making, including the making of scientific inferences, is the role of a vast web of beliefs lodged in the human mind, as also of a huge repertoire of heuristics, that constitute an important component of ‘unconscious intelligence’. Finally, human cognitive activity is dependent in a large measure on emotions and affects, that operate mostly at an unconscious level. Of special importance in scientific inferential activity is the process of hypothesis making, which is examined in this book, along with the above aspects of inductive inference, at considerable depth. The book focuses on the inadequacy of the viewpoint of naive realism in understanding the contextual nature of scientific theories, where a cumulative progress towards an ultimate truth about Nature appears to be too simplistic a generalization. It poses a critique to the commonly perceived image of science which is seen as the last word in logic and objectivity, the latter in the double sense of being independent of individual psychological propensities and, at the same time, approaching a correct understanding of the workings of a mind-independent nature. Adopting the naturalist point of view, it examines the essential tension between the cognitive endeavours of individuals and scientific communities, immersed in belief systems and cultures, on the one hand, and the engagement with a mind-independent reality on the other. In the end, science emerges as an interpretation of nature, which is perceived by us only contextually, as successively emerging cross-sections of limited scope and extent. Successive waves of theory building in science appear as episodic and kaleidoscopic changes in perspective as certain in-built borders are crossed, rather than as a cumulative progress towards some ultimate truth. While written in an informal and conversational style, the book raises a number of deep and intriguing questions located at the interface of cognitive psychology and philosophy of science, meant for both the general lay reader and the specialist. Of particular interest is the way it explores the role of belief (aided by emotions and affects) in making the process of inductive inference possible since belief is a subtle though all-pervasive cognitive factor not adequately investigated in the current literature.

We discuss the variety of sorts of sympathy Hume recognizes, the extent to which he thinks our sympathy with others’ feelings depends on inferences from the other’s expression, and from her perceived situation, and consider also whether he later changed his views about the nature and role of sympathy, in particular its role in morals.

Although both philosophers and scientists are interested in how to obtain reliable knowledge in the face of error, there is a gap between their perspectives that has been an obstacle to progress. By means of a series of exchanges between the editors and leaders from the philosophy of science, statistics and economics, this volume offers a cumulative introduction connecting problems of traditional philosophy of science to problems of inference in statistical and empirical modelling practice. Philosophers of science and scientific (...) practitioners are challenged to reevaluate the assumptions of their own theories - philosophical or methodological. Practitioners may better appreciate the foundational issues around which their questions revolve and thereby become better 'applied philosophers'. Conversely, new avenues emerge for finally solving recalcitrant philosophical problems of induction, explanation and theory testing. (shrink)

In a recent book, Anjan Chakravartty builds a case for a particular conception of the relationship of science to metaphysics. The main novel feature in his account of scientific ontology is his construction of a metaphysical distance measure. Some ontological claims are close to the science that informs those claims, and some are further away. The distance is a measure of the epistemic risk one takes in asserting the claim: the further from the empirical base, the greater the risk. But (...) conversely, claims far from the empirical base can serve explanatory and unificatory purposes regarding claims closer in. Since different philosophers have different attitudes towards epistemic risk, Chakravartty endorses a pluralism about scientific ontology. Chakravartty illustrates his arguments concerning scientific ontology by considering what we can infer from the Standard Model of particle physics concerning the ontological status of the structures and entities it describes. I argue that, while this case study initially appears to support Chakravartty’s arguments, on closer inspection it suggests a more deflationary approach to scientific ontology. (shrink)

Many people follow Grice in thinking that all conversational implicatures are cancellable. And often enough, they use this insight as a test for conversational implicatures. If you want to find out whether something is a conversational implicature, the test has it, you should ask yourself whether the thing in question is cancellable; if you find that it is not cancellable, you can infer that it is not a conversational implicature. If you find that it is cancellable, (...) you can infer that it might well be a conversational implicature and that you should now do further testing. Various philosophers and linguists have questioned the test however. Some have held that Grice's cancellability claim is subject to counterexamples and that the test is not reliable. Others have argued that even though Grice's claim can be defended against the examples in question, the test is not as informative as people have hoped. This article provides an overview of the recent discussion on the cancellability test and suggests a way forward. (shrink)

In this article, we first study abduction in human dialogues. Given an utterance, objective abduction produces a hearer’s belief that could explain the utterance, while subjective abduction produces a hearer’s belief that could explain the belief state of a speaker. Different types of abduction are formulated using propositional epistemic logic. We next consider conversational implicature used as pragmatic inference in speech acts. Two conflicting implicatures, Q-implicature and I-implicature, are formulated and contrasted with abduction. We also argue how speakers (...) could use abduction or conversational implicature for the purpose of misleading hearers. (shrink)

This interdisciplinary work is a collection of major essays on reasoning: deductive, inductive, abductive, belief revision, defeasible, cross cultural, conversational, and argumentative. They are each oriented toward contemporary empirical studies. The book focuses on foundational issues, including paradoxes, fallacies, and debates about the nature of rationality, the traditional modes of reasoning, as well as counterfactual and causal reasoning. It also includes chapters on the interface between reasoning and other forms of thought. In general, this last set of essays represents (...) growth points in reasoning research, drawing connections to pragmatics, cross-cultural studies, emotion and evolution. (shrink)

In this paper, I present an experience of philosophical dialogue with small children in a public school in Bari, Italy in the context of the Philosophia Ludens for Children project. I present the experience, including the transcripts of six conversations with several groups of children, and then draw some inferences concerning the importance of the relationship between Universities and schools; the philosophical strength of both children’s commitment and philosophical ideas and their positive understanding of childhood.

In this paper we show that it is possible to eliminate the converse operator from the propositional dynamic logic CPDL (Converse PDL), without compromising the soundness and completeness of inference for it. Specifically we present an encoding of CPDL formulae into PDL that eliminates the converse programs from a CPDL formula, but adds enough information so as not to destroy its original meaning with respect to satisfiability, validity, and logical implication. Notably, the resulting PDL formula is polynomially related to (...) the original one. This fact allows one to build inference procedures for CPDL, by encoding CPDL formulae into PDL, and then running an inference procedure for PDL. (shrink)

Standard definitions of validity are designed to preserve truth from the premises to the conclusion. However, it seems possible to construct arguments that contain sentences in the imperative mood. Such sentences are incapable of being true or false, so the standard definitions cannot capture the validity of these imperative arguments. Bernard Williams offers an argument that imperative inference is impossible: two imperatives will always have different permissive presuppositions, so a speaker will have to change his mind before uttering a (...) second imperative, and so imperatives cannot ever be accumulated into a set of premises. I offer four objections to Williams’ argument: (1) Permissive presuppositions are analogous to conversational implicature, and so should be ignored when formulating imperative arguments. (2) There are other valid argument forms, which Williams does not consider, that do not suffer from different permissive presuppositions. (3) There are explanations for the change in permissive presuppositions in Williams’ example other than a change of mind, so the different permissive presuppositions do not have to prevent accumulation. Finally, (4) Williams accepts enough logical relations between imperatives (contradiction and a form of negation) for a definition of a valid imperative inference to follow naturally. (shrink)

In this conversation, American philosopher Robert Brandom talks about the historical background of his inferentialism, reconstructing the influence of his teachers Wilfrid Sellars and Richard Rorty.

This chapter investigates the computational consequences of a broadly Gricean view of language use as intentional activity. In this view, dialogue rests on coordinated reasoning about communicative intentions. The speaker produces each utterance by formulating a suitable communicative intention. The hearer understands it by recognizing the communicative intention behind it. When this coordination is successful, interlocutors succeed in considering the same intentions— that is, the same representations of utterance meaning—as the dialogue proceeds. In this paper, I emphasize that these intentions (...) can be formalized; we can provide abstract but systematic representations that spell out what a speaker is trying to do with an utterance. Such representations describe utterances simultaneously as the product of our knowledge of grammar and as actions chosen for a reason. In particular, they must characterize the speaker’s utterance in grammatical terms, provide the links to the context that the grammar requires, and so arrive at a contribution that the speaker aims to achieve. Because I have implemented this formalism, we can regard it as a possible analysis of conversational processes at the level of computational theory. Nevertheless, this analysis leaves open what the nature of the biological computation involved in inference to intentions is, and what regularities in language use support this computation. (shrink)

Affect has been found to play important role in word and sentence processing. What is less understood is the role it plays in the process by which interlocutors arrive at what speakers mean. In the present review, the way affect modulates how we comprehend what others mean is examined. This is done by reviewing studies that have employed experimental methods using both written materials and spoken utterances. The goal of the present review is to better understand how the inferential process (...) is framed by affective factors and to propose ways of integrating affectivity into pragmatics. In Part 1, the motivation for the present review is explicated. In Part 2, experimental evidence is presented and suggestions are offered about how to best operationalise variables crucial for disentangling affect from other mechanisms that contribute to utterance interpretation. In Part 3, central notions of pragmatics are discussed with regard to affectivity, which it is proposed that, if construed as a goal-oriented activity that serves interpersonal configuration, can account for several pragmatic phenomena.

The author demonstrates the validity of the inference of particular sentences from universal sentences through the Aristotelian simple conversion and accidental conversion of categorical propositions.

Drawing on the theory of ‘mental models’, I have previously shown that the valid syllogisms in the Aristotelian logical system, including all of its figures and moods, are very easy for the human mind. Indeed, they can even be used to predict inferences that people can make with quantified sentences. In this paper, I further argue that, if mental models theory is correct, then also the Aristotelian conversion rules are not hard for the human mind. My account here again focuses (...) on the distinction made by the mental models theory between canonical and noncanonical models. (shrink)

Advocates of cladistic parsimony methods have invoked the philosophy of Karl Popper in an attempt to argue for the superiority of those methods over phylogenetic methods based on Ronald Fisher's statistical principle of likelihood. We argue that the concept of likelihood in general, and its application to problems of phylogenetic inference in particular, are highly compatible with Popper's philosophy. Examination of Popper's writings reveals that his concept of corroboration is, in fact, based on likelihood. Moreover, because probabilistic assumptions are (...) necessary for calculating the probabilities that define Popper's corroboration, likelihood methods of phylogenetic inference—with their explicit probabilistic basis—are easily reconciled with his concept. In contrast, cladistic parsimony methods, at least as described by certain advocates of those methods, are less easily reconciled with Popper's concept of corroboration. If those methods are interpreted as lacking probabilistic assumptions, then they are incompatible with corroboration. Conversely, if parsimony methods are to be considered compatible with corroboration, then they must be interpreted as carrying implicit probabilistic assumptions. Thus, the non-probabilistic interpretation of cladistic parsimony favored by some advocates of those methods is contradicted by an attempt by the same authors to justify parsimony methods in terms of Popper's concept of corroboration. In addition to being compatible with Popperian corroboration, the likelihood approach to phylogenetic inference permits researchers to test the assumptions of their analytical methods (models) in a way that is consistent with Popper's ideas about the provisional nature of background knowledge.

This paper demonstrates an empirical analysis of the visual order of membership categories in a way consistent with both an early ethnomethodological research interest and recent arguments in membership categorization analysis. Early ethnomethodological studies have highlighted that we can infer and understand the membership categories of observed people about whom we have no information in advance, even without talking to them. Recent membership categorization analysts have argued the methodological importance of using video data. Given this, fictional films serve as video (...) data to advance the investigation into the visual order of membership categories since audiences do not know the fictional characters’ information in advance and cannot talk to them. We analyze how potential audiences understand fictional characters’ membership categories and how production crew members organize the visual and conversational order of membership categories. The analysis illustrates that our practical inferences of fictional characters’ membership categories are based on conversations among characters and visually available information. Such visually available information includes environments and lighting, as well as characters’ clothes, body orientations, facial expressions, and physical distance from each other. In other words, production crew members of fictional films design the visual and conversational order for remote audiences by arranging visually available information and fictional characters’ conversations. The findings provide insights into the “possible correctness” and “defeasibility” of membership categorization practices. Particularly regarding fictional characters’ membership categories, production crew members can employ the “possible correctness” and “defeasibility” of categorization practices to mislead audiences.

This article considers the different approaches to cognition in conversation analysis and discursive psychology. Its points are illustrated through a critical but appreciative consideration of an article by Drew in which he uses conversation analysis to identify ‘cognitive moments’ in interaction. Problems are identified with Drew’s analysis and the conclusions he draws. In particular, he a) presupposes a dualistic division between depth and surface; b) makes circular inferences from conventional conversational patterns to underlying cognitive entities; c) presupposes that the (...) underlying cognitive entities influence conduct. It is argued that none of these things is required by conversation analysis; rather Drew is imposing cognitivist assumptions on conversational materials. Discursive psychology’s approach focuses on cognitive issues in terms of how they are constructed and oriented to in interaction; its virtues are pressed. (shrink)

Between the first and second editions of A System of Logic, John Stuart Mill underwent a startling conversion from an uncompromising frequentist philosophy of probability to a thoroughly Bayesian degree-of-belief view. The conversion was effected by correspondence with the eminent scientist Sir John Herschel, to whom Mill already owed what have become known as Mill's Methods of Experimental Inference. We present the relevant correspondence, and discuss the extent of Mill's conversion.

I defend an alternative theory of conversational implicatures that does without Grice's notion of making‐as‐if‐to‐say. This theory characterises conversationally implicating that p as a way to mean that p by saying that q or by saying nothing. Cases that Grice's theory cannot capture are captured, and cases that Grice's theory misdescribes are correctly described. A distinction between conversational implicatures and pragmatic inferences from what speakers express is required, as well as a non‐implicature treatment of figurative speech.

The purpose of this study is to compile a selection of the various formalisms found in conversation theory to introduce readers to Pask's discursive algebra. In this way, the text demonstrates how concept sharing and concept formation by means of the interaction of two participants may be formalized. The approach taken in this study is to examine the formal notation system used by Pask and demonstrate how such formalisms may be used to represent concept sharing and concept formation through conversation. (...) The compilation of the discursive algebra using the framework provided by conversation theory could potentially be used as an auxiliary framework to study conversational interactions in multi-agent systems theory.

It can be demonstrated in a very straightforward way that confirmation and evidence as spelled out by us can vary from one case to the next, that is, a hypothesis may be weakly confirmed and yet the evidence for it can be strong, and conversely, the evidence may be weak and the confirmation strong. At first glance, this seems puzzling; the puzzlement disappears once it is understood that confirmation is of single hypotheses, in which there is an initial degree of (...) belief which is adjusted up or down as data accumulate, whereas evidence always has to do with a comparison of one hypothesis against another with respect to the data and is belief-independent. Confusing them is, we suggest, a plausible source of the so-called “base-rate fallacy” identified by Kahneman and Tversky which leads most of us to make mistaken statistical inferences. It is also in the background, or so we argue in some detail, of the important policy controversies concerning human-induced global warming. (shrink)

Epistemic closure refers to the assumption that humans are able to recognize what entails or contradicts what they believe and know, or more accurately, that humans’ epistemic states are closed under logical inferences. Epistemic closure is part of a larger theory of mind ability, which is arguably crucial for downstream NLU tasks, such as inference, QA and conversation. In this project, we introduce a new automatically constructed natural language inference dataset that tests inferences related to epistemic closure. We (...) test and further fine tune the model RoBERTa-large-mnli on the new dataset, with limited positive results. (shrink)

American History X (hereafter AHX) has been accused by numerous critics of a morally dangerous cinematic seduction: using stylish cinematography, editing, and sound, the film manipulates the viewer through glamorizing an immoral and hate-filled neo-nazi protagonist. In addition, there’s the disturbing fact that the film seems to accomplish this manipulation through methods commonly grouped under the category of “fascist aesthetics.” More specifically, AHX promotes its neo-nazi hero through the use of several filmic techniques made famous by Nazi propagandist Leni Riefenstahl. (...) Now most critics admit that, in the end, the film claims to denounce racism and attempts to show us the conversion of the protagonist to the path of righteousness, but they complain that nonetheless the film (perhaps unintentionally) ends up implicitly promoting the immoral worldview it rather superficially professes to reject in its final act. This charge of hypocrisy is connected to another worry: the moral conversion in the film is said to fall flat because the intellectual resources on display to support the character’s racism are not counterbalanced by equally explicit (but superior) arguments for the anti-racist position ultimately embraced by the character. In other words, just as the devil is said to get all the good lines in Milton’s Paradise Lost, in AHX the racists get all the arguments. This has been taken to be a morally problematic flaw of the film. Critics lament that Derek’s conversion seems to result not from relevant logical inferences and valid rational argumentation but from overly simplistic and arguably egoistic insights (e.g., “has anything you've done made your life better?”) combined, perhaps, with a hackneyed cliché (in prison, one of his best friends is a black person!) In this paper I’ll attempt to rebut these charges and defend the film as a powerful, and powerfully moral, work of art. I’ll be suggesting that the seductive techniques employed allow for many viewers a degree of sympathy towards the protagonist that is crucial, both for making that character’s more horrific actions especially unsettling, and also for making his eventual conversion plausible and ultimately compelling. I’ll also argue that the manner in which his conversion is presented is in fact subtler than many critics have allowed: Derek’s transformation is not artificial or implausible but is depicted as resulting from a cumulative series of emotionally powerful life events and personal engagements. It is certainly true that it is not represented in the way some would seemingly have preferred, i.e. as straightforwardly resulting from a process of gradual intellectual improvement in Derek’s reasoning on questions of race and politics. However, I’ll argue that the decidedly emotional basis of his moral evolution is both refreshingly realistic and no hindrance to accepting his conversion as rational. Finally, properly understanding the legitimacy of the emotional foundations of much moral thought will also allow us to appreciate the ways in which our initial worries about this film’s (not insignificant) ability to persuade viewers through the engagement of emotions need not, in itself, be seen as a barrier to endorsing the film as a morally praiseworthy work.

Four experiments investigated uncertainty about a premise in a deductive argument as a function of the expertise of the speaker and of the conversational context. The procedure mimicked everyday reasoning in that participants were not told that the premises were to be treated as certain. The results showed that the perceived likelihood of a conclusion was greater when the major or the minor premise was uttered by an expert rather than a novice (Experiment 1). The results also showed that (...) uncertainty about the conclusion was higher when the major premise was uttered by a novice and an alternative premise by an expert, compared to when the major premise was uttered by an expert and the alternative by a novice (Experiment 2). Similarly, the believability of a conclusion was considerably lower when the minor premise was uttered by a novice and denied by an expert, as opposed to when an expert uttered the minor premise and a novice denied it (Experiment 3). Experiment 4 showed that the nature of the uncertainty induced by a denial of the minor premise depended on whether or not the context was a conversation. These results pose difficult problems for current theories of reasoning, as current theories are based on the results of experiments in which the premises are treated as certain. Our discussion of the results emphasises the importance of pragmatics in reasoning, namely, the role of general knowledge about the world in assessing the probability of a premise uttered by an expert or a novice and the role of interpretations of the premise based on pragmatic inferences in revising these initial probabilities.

There is substantial support for the general idea that a formalization of comprehenders' expectations about the likely next word in a sentence helps explaining data related to online sentence processing. While much research has focused on syntactic, semantic, and discourse expectations, the present event‐related potentials (ERPs) study investigates neurolinguistic correlates of pragmatic expectations, which arise when comprehenders expect a sentence to conform to Gricean Maxims of Conversation. For predicting brain responses associated with pragmatic processing, we introduce a formal model of (...) such Gricean pragmatic expectations, using an idealized incremental interpreter. We examine whether pragmatic expectancies derived from this model modulate the amplitude of the N400, a component that has been associated with predictive processing. As part of its parameterization, the model distinguishes genuine pragmatic interpreters, who expect maximally informative true utterances, from literal interpreters, who only expect truthfulness. We explore the model's non‐trivial predictions for an experimental setup which uses picture‐sentence verification with ERPs recorded at several critical positions in sentences containing the scalar implicature trigger some. We find that Gricean expectations indeed affect the N400, largely in line with the predictions of our model, but also discuss discrepancies between model predictions and observations critically.

First published in 1990, Charles Taylor’s essay ‘Comparison, History Truth’ is an extended reflection on some of the problems involved in interpreting other cultures and eras. This essay’s explicit focus is the work of historians and anthropologists. Taylor mentions students of religion in the same breath, but I infer that by this he means students of comparative religions or the history of religions. I suggest that for all its emphasis on conversation, Taylor’s depiction of the comparativist’s enterprise is ultimately one-sided, (...) depicting those who are interpreted as hermeneutic patients rather than hermeneutic agents. I raise some problems with the language of distortion employed throughout the essay. I identify a number of ways in which Taylor’s thought on cross-cultural understanding dovetails with that of Anthony Kwame Appiah in his recent book Cosmopolitanism: Ethics in a World of Strangers. I conclude, however, that there is an important issue addressed by Taylor which Appiah neglects. This is the question of how western comparativists, who according to Taylor proceed from some belief the equal validity of all cultures, engage cultures that do not share this belief. (shrink)

In 'A Puzzle about Belief' Saul Kripke appeals to a principle of disquotation that allows us to infer a person's beliefs from the sentences to which she assents (in certain conditions). Kripke relies on this principle in constructing some famous puzzle cases, which he uses to defend the Millian view that the sole semantic function of a proper name is to refer to its bearer. The examples are meant to undermine the anti-Millian objection, grounded in traditional Frege-cases, that truth-value is (...) not always maintained when co-referential names are intersubstituted in belief reports. I argue here that our disquotational practice is sensitive to certain shifts in conversational context, and it is only if we overlook these shifts - if we 'misdisquote' - that we can draw the conclusions Kripke wants to draw from his examples. In the wake of this conclusion, I provide a 'contextualist' treatment of Kripke's puzzle cases. I show how this treatment is motivated by certain norms of rationality, and I defend these norms against an intriguing 'anti-Cartesian' theory of mind. Throughout the paper, I develop the larger implications that my treatment of Kripke's argument has for the semantic theory of names and belief reports, and, more generally, for our picture of the relation between linguistic behaviour and our states of mind.

The aim of this project was to explore the possibility of constructing a psychologic inference engine that might enhance introspective self-awareness by delivering inferences about a user based on what he said in interactive dialogues about his closest opposite-sex relation. To implement this aim, we developed a computer program (guru) with the capacity to simulate human conversation in colloquial natural language. The psychologic inferences offered represent the authors' simulations of their commonsense psychology responses to expected user-input expressions. The heuristics (...) of the natural language processor and its relation to output responses are described in enough detail for the operations of the implementation to be understood. Evaluation of this new cognitive agent presents, we hope, puzzles for artificial intelligence and cognitive science. (shrink)

In Enthymemes and Topoi in Dialogue, Ellen Breitholtz presents a novel and precise account of reasoning from an interactional perspective. The account draws on the concepts of enthymemes and topoi, originating in Aristotelian rhetoric and dialectic, and integrates these in a formal dialogue semantic account using TTR, a type theory with records. Argumentation analysis and formal approaches to reasoning often focus the logical validity of arguments on inferences made in discourse from a god's-eye perspective. In contrast, Breitholtz's account emphasises the (...) individual perspectives of interlocutors and the function and acceptability of their reasoning in context. This provides an analysis of interactions where interlocutors have access to different topoi and therefore make different inferences. (shrink)

The “Averroism” of Ibn Ṭumlūs (d. 620/1223) has already been attested to by both biographers and textual evidence. Conversely, a close reading of a section in his Kitāb al-Qiyās of his Mukhtaṣar fī al-mantiq (Compendium on Logic) reveals that this “Averroism” has a specific resonance. Unlike Ibn Rushd (d. 595/1198), Ibn Ṭumlūs belongs to this group of philosophers who dedicated a special section to the examination of jurisprudential inferences, titled by him “al-Qawl fī al-maqāyīs al-fiqhiyyah”, which is a part of (...) his Kitāb al-Qiyās. In this article, first, I will introduce the text of Ibn Ṭumlūs, and present its teaching by placing it in its intellectual context, namely in the light of al-Fārābī’s, al-Ghazālī’s, and Ibn Rushd’s relevant texts. Then, I provide an English translation followed by a critical edition of the Arabic text. The purpose is to highlight the value (and limitations) of Ibn Ṭumlūs’s effort, based on al-Fārābī (d. 339/950), al-Ghazālī (d. 505/1111) and Ibn Rushd, to apply Aristotelian syllogistic model to the jurisprudential inferences.

This paper presents preliminary findings of the project [name omitted for anonymity]. This interdisciplinary project builds on Argumentation theory and developmental sociocultural psychology for the study of children’s argumentation. We reconstruct children’s inferences in adult-child and child-child dialogical interaction in conversation in different settings. We focus in particular on implicit premises using the Argumentum Model of Topics for the reconstruction of the inferential configuration of arguments. Our findings reveal that sources of misunderstandings are more often than not due to misalignments (...) of implicit premises between adults and children; these misalignments concern material premises rather than the inferential-procedural level.

Deduction leads to causal explanation in phylogenetic inference when the evidence, the systematic character, is conceptualized as a transformation series. Also, the deductive entailment of modus tollens is satisfied when those kinds of events are operationalized as patristic difference. Arguments to the contrary are based largely on the premise that character-states are defined intensionally as objects, in terms of similarity relations. However, such relations leave biologists without epistemological access to the causal explanation and explanatory power of historical statements. Moreover, (...) the prediction-making to which those kinds of relations are limited in practice can lead to a category error—the mental conversion of an abstraction into a thing . The latter practices and problems characterize pattern cladistics, taxa being interpreted as homeostatic property cluster natural kinds, and other instrumentalist research programs. (shrink)
