Inquiry into the meaning of logical terms in natural language (‘and’, ‘or’, ‘not’, ‘if’) has generally proceeded along two dimensions. On the one hand, semantic theories aim to predict native speaker intuitions about the natural language sentences involving those logical terms. On the other hand, logical theories explore the formal properties of the translations of those terms into formal languages. Sometimes, these two lines of inquiry appear to be in tension: for instance, our best logical investigation into conditional connectives may (...) show that there is no conditional operator that has all the properties native speaker intuitions suggest if has. Indicative conditionals have famously been the source of one such tension, ever since the triviality proofs of both Lewis (1976) and Gibbard (1981) established conclusions which are in prima facie tension with ordinary judgments about natural language indicative conditionals. In a recent series of papers, Branden Fitelson has strengthened both triviality results (Fitelson 2013, 2015, 2016), revealing a common culprit: a logical schema known as IMPORT-EXPORT. Fitelson’s results focus the tension between the logical results and ordinary judgments, since IMPORT-EXPORT seems to be supported by intuitions about natural language. In this paper, we argue that the intuitions which have been taken to support IMPORT-EXPORT are really evidence for a closely related, but subtly different, principle. We show that the two principles are independent by showing how, given a standard assumption about the conditional operator in the formal language in which IMPORT-EXPORT is stated, many existing theories of indicative conditionals validate one, but not the other. Moreover, we argue that once we clearly distinguish these principles, we can use propositional anaphora to show that IMPORT-EXPORT is in fact not valid for natural language indicative conditionals (given this assumption about the formal conditional operator). This gives us a principled and independently motivated way of rejecting a crucial premise in many triviality results, while still making sense of the speaker intuitions which appeared to motivate that premise. We suggest that this strategy has broad application and an important lesson: in theorizing about the logic of natural language, we must pay careful attention to the translation between the formal languages in which logical results are typically proved, and natural languages which are the subject matter of semantic theory.

Building on existing studies suggesting that corporate social performance (CSP) is important in the job choice process, the authors investigate job seekers’perceptions of importance of CSP and explore effects of CSP dimensions on organizational attractiveness. Job seekers consider CSP important to assessment of firms and rate five specific CSP dimensions (environment, community relations, employee relations, diversity, and product issues) as more important than six other CSP dimensions. Using signaling theory and social identity theory, the authors hypothesize differences in effects of (...) CSP data on ratings of employer attractiveness and find that environment, community relations, and diversity dimensions have the largest affect on attractiveness ratings. (shrink)

Adults and children spontaneously produce gestures while they speak, and such gestures appear to support and expand on the information communicated by the verbal channel. Little research, however, has been carried out to examine the role played by gesture in the listener's representation of accumulating information. Do listeners attend to the gestures that accompany narrative speech? In what kinds of relationships between gesture and speech do listeners attend to the gestural channel? If listeners do attend to information received in gesture, (...) how is this information represented— is it 'tagged' as originating in the gestural channel? In this article research is described that addresses these questions. Results show that listeners do attend to information conveyed in gesture, when that information supplements or even contradicts the information conveyed by speech. And information received via gesture is available for retelling in speech. These results are taken to demonstrate that gesture is not taken by the listener to be epiphenomenal to the act of speaking, or a simple manual translation of speech. But they also suggest that the information conveyed in a discourse may be represented in a manner that is neither gesture nor language, although accessible to both channels. (shrink)

We focus on the production of efficient descriptions of objects, actions and events. We define a type of efficiency, textual economy, that exploits the hearer’s recognition of inferential links to material elsewhere within a sentence. Textual economy leads to efficient descriptions because the material that supports such inferences has been included to satisfy independent communicative goals, and is therefore overloaded in the sense of Pollack [18]. We argue that achieving textual economy imposes strong requirements on the representation and reasoning used (...) in generating sentences. The representation must support the generator’s simultaneous consideration of syntax and semantics. Reasoning must enable the generator to assess quickly and reliably at any stage how the hearer will interpret the current sentence, with its (incomplete) syntax and semantics. We show that these representational and reasoning requirements are met in the SPUD system for sentence planning and realization. (shrink)

:This interview ranges across a number of topics relevant to Vinciane Despret's thought: the history and philosophy of ethology; animal culture; stories and storytelling; feminism; philosophical anthropology; animal studies; collaborative research; and animals in laboratories, in the field, on farms, and in books. It touches on thinkers and artists including Isabelle Stengers, Donna Haraway, Bruno Latour, Jacques Derrida, Gilles Deleuze, and Luc Petton.

We begin to glimpse what the concept of zoopolitics means in Derrida, namely the place of an analysis and an interpretation of our political modernity in its links with the animality of the human and that of the animal, or more precisely still in its links with the proper of the human [le propre de l’homme] as it thinks of itself as a political and rational animal, in opposition to the animal that would be neither political nor rational. It must, (...) however, be noted right away that despite what might be called the animalistic tropism of Derridean deconstruction, it does not include a thesis maintaining the continuity between human and animal. If it is unquestionable that deconstruction refrains from making animality .. (shrink)

Roberto Marchesini is an Italian philosopher and ethologist whose work is significant for the rethinking of animality and human–animal relations. Throughout such important books as Il dio Pan,Il concetto di soglia, Post-human, Intelligenze plurime, Epifania animale, and Etologia filosofica he offers a scathing critique of reductive, mechanistic models of animal behaviour, as well as a positive contribution to zooanthropological and phenomenological methods for understanding animal life. Centred on the dynamic and performative field of interactions and relations in the world, his (...) critical and speculative approach to the cognitive life sciences offers a vision of animals as acting subjects and bearers of culture, whose action and agency is also indispensable to human culture. In tracing the ways in which we share our lives and histories with animals in different contexts of interaction, Marchesini's cutting-edge philosophical ethology also contributes to an overarching philosophical anthropology of the human as the animal that most requires the presence and input of other animals.

A fundamental fact about human minds is that they are never truly alone: all minds are steeped in situated interaction. That social interaction matters is recognized by any experimentalist who seeks to exclude its influence by studying individuals in isolation. On this view, interaction complicates cognition. Here, we explore the more radical stance that interaction co-constitutes cognition: that we benefit from looking beyond single minds toward cognition as a process involving interacting minds. All around the cognitive sciences, there are approaches (...) that put interaction center stage. Their diverse and pluralistic origins may obscure the fact that collectively, they harbor insights and methods that can respecify foundational assumptions and fuel novel interdisciplinary work. What might the cognitive sciences gain from stronger interactional foundations? This represents, we believe, one of the key questions for the future. Writing as a transdisciplinary collective assembled from across the classic cognitive science hexagon and beyond, we highlight the opportunity for a figure-ground reversal that puts interaction at the heart of cognition. The interactive stance is a way of seeing that deserves to be a key part of the conceptual toolkit of cognitive scientists. (shrink)

Bradley offers a quick and convincing argument that no Boolean semantic theory for conditionals can validate a very natural principle concerning the relationship between credences and conditionals. We argue that Bradley’s principle, Preservation, is, in fact, invalid; its appeal arises from the validity of a nearby, but distinct, principle, which we call Local Preservation, and which Boolean semantic theories can non-trivially validate.

Social contract theorists often take the ideal contract to be the agreement or bargain individuals would make in some privileged choice situation. Recently, experimental philosophers have explored this kind of decision-making in the lab. One rather robust finding is that the exact circumstances of choice significantly affect the kinds of social arrangements experimental subjects unanimously endorse. Yet prior work has largely ignored the question of which of the many competing descriptions of the original position subjects find most compelling. This paper (...) aims to address this gap, exploring how attractive experimental subjects find various characterizations of these circumstances of choice. We find evidence suggesting that no one choice situation can fulfill the role that social contract theorists have hoped it would play. We also find that, contrary to what some prominent social contract theorists have expected, there is no robust relationship between an individual’s ranking of distributive principles and their ranking of various descriptions of the original position. In conclusion, we discuss the broader implications of these results for political philosophy. (shrink)

The evolution of sex in eukaryotes represents a paradox, given the “twofold” fitness cost it incurs. We hypothesize that the mutational dynamics of the mitochondrial genome would have favored the evolution of sexual reproduction. Mitochondrial DNA (mtDNA) exhibits a high‐mutation rate across most eukaryote taxa, and several lines of evidence suggest that this high rate is an ancestral character. This seems inexplicable given that mtDNA‐encoded genes underlie the expression of life's most salient functions, including energy conversion. We propose that negative (...) metabolic effects linked to mitochondrial mutation accumulation would have invoked selection for sexual recombination between divergent host nuclear genomes in early eukaryote lineages. This would provide a mechanism by which recombinant host genotypes could be rapidly shuffled and screened for the presence of compensatory modifiers that offset mtDNA‐induced harm. Under this hypothesis, recombination provides the genetic variation necessary for compensatory nuclear coadaptation to keep pace with mitochondrial mutation accumulation. (shrink)

Discussions of the non-identity problem presuppose a widely shared intuition that actions or policies that change who comes into existence don't, thereby, become morally unproblematic. We hypothesize that this intuition isn’t generally shared by the public, which could have widespread implications concerning how to generate support for large-scale, identity-affecting policies relating to matters like climate change. To test this, we ran a version of the well-known dictator game designed to mimic the public's behavior over identity-affecting choices. We found the public (...) does seem to behave more selfishly when making identity-affecting choices, which should be concerning. We further hypothesized that one possible mechanism is the notion of harm the public uses in their decision-making and find that substantial portions of the population seem to each employ distinct notions of harm in their normative thinking. These findings raise puzzling features about the public’s normative thinking that call out for further empirical examination. (shrink)

What does it mean to consider the world of AI through a Christian lens? Rapid developments in AI continue to reshape society, raising new ethical questions and challenging our understanding of the human person. Encountering Artificial Intelligence draws on Pope Francis’ discussion of a culture of encounter and broader themes in Catholic social thought in order to examine how current AI applications affect human relationships in various social spheres and offers concrete recommendations for better implementation. The document also explores questions (...) regarding personhood, consciousness, and the kinds of relationships humans might have with even the most advanced AI. Through these discussions, this book investigates the theoretical and practical challenges to interpersonal encounter raised by the age of AI.

ObjectiveTo compare techniques for computing clustering and switching scores in terms of agreement, correlation, and empirical value as predictors of incident cognitive impairment.MethodsWe transcribed animal and letter F fluency recordings on 640 cases of ICI and matched controls from a national epidemiological study, amending each transcription with word timings. We then calculated clustering and switching scores, as well as scores indexing speed of responses, using techniques described in the literature. We evaluated agreement among the techniques with Cohen’s κ and calculated (...) correlations among the scores. After fitting a base model with raw scores, repetitions, and intrusions, we fit a series of Bayesian logistic regression models adding either clustering and switching scores or speed scores, comparing the models in terms of several metrics. We partitioned the ICI cases into acute and progressive cases and repeated the regression analysis for each group.ResultsFor animal fluency, we found that models with speed scores derived using the slope difference algorithm achieved the best values of the Watanabe–Akaike Information Criterion, but with good net reclassification improvement only for the progressive group. For letter fluency, different models excelled for prediction of acute and progressive cases. For acute cases, NRI was best for speed scores derived from a network model, while for progressive cases, the best model used clustering and switching scores derived from the same network model. Combining variables from the best animal and letter F models led to marginal improvements in model fit and NRI only for the all-cases and acute-cases analyses.ConclusionSpeed scores improve a base model for predicting progressive cognitive impairment from animal fluency. Letter fluency scores may provide complementary information. (shrink)

As the capabilities of Artificial Intelligence (AI) have increased over recent years, so have the challenges of how to govern its usage. Consequently, prominent stakeholders across academia, government, industry, and civil society have called for states to devise and deploy principles, innovative policies, and best practices to regulate and oversee these increasingly powerful AI tools. Developing a robust AI governance system requires extensive collective efforts throughout the world. It also raises old questions of politics, democracy, and administration, but with the (...) new challenges posed by AI's growing influence on markets, governing structures, international relations, healthcare, science, and political activism. The Oxford Handbook of AI Governance delineates the scope of these issues and addresses the key questions of AI governance. Across forty-nine chapters, organized in nine major sections, the Handbook covers the theoretical and ethical foundations of AI governance, different frameworks for developing a governance structure for AI, practical perspectives on AI governance in different policy domains, economic analyses of AI governance, and concrete lessons about the impact of AI governance domestically and internationally. Chapter authors come from a wide set of disciplines, areas of study, and cultural backgrounds, providing a global perspective on AI governance. (shrink)

Psychiatry is rapidly adopting digital phenotyping and artificial intelligence/machine learning tools to study mental illness based on tracking participants’ locations, online activity, phone and text message usage, heart rate, sleep, physical activity, and more. Existing ethical frameworks for return of individual research results (IRRs) are inadequate to guide researchers for when, if, and how to return this unprecedented number of potentially sensitive results about each participant’s real-world behavior. To address this gap, we convened an interdisciplinary expert working group, supported by (...) a National Institute of Mental Health grant. Building on established guidelines and the emerging norm of returning results in participant-centered research, we present a novel framework specific to the ethical, legal, and social implications of returning IRRs in digital phenotyping research. Our framework offers researchers, clinicians, and Institutional Review Boards (IRBs) urgently needed guidance, and the principles developed here in the context of psychiatry will be readily adaptable to other therapeutic areas.

The study of intellectual humility is still in its early stages and issues of definition and measurement are only now being explored. To inform and guide the process of defining and measuring this important intellectual virtue, we conducted a series of studies into the implicit theory – or ‘folk’ understanding – of an intellectually humble person, a wise person, and an intellectually arrogant person. In Study 1, 350 adults used a free-listing procedure to generate a list of descriptors, one for (...) each person-concept. In Study 2, 335 adults rated the previously generated descriptors by how characteristic each was of the target person-concept. In Study 3, 344 adults sorted the descriptors by similarity for each person-concept. By comparing and contrasting the three person-concepts, a complex portrait of an intellectually humble person emerges with particular epistemic, self-oriented, and other-oriented dimensions.

This roundtable brings together contributions from nine senior, mid-career and junior scholars who work on the history of science in pre-1800 Islamicate societies. The contributions reflect upon some of the challenges that have historically constrained the subfield, how they have sought to overcome them, and what they see as some of the more productive and fruitful turns the field has taken and/or should take in the future. A central trend in all contributions is how they seek to confront the combined (...) weight of colonialism, Orientalism, and the teleological history of science that continues to haunt contemporary discussions in both academia and the general public with regards to science in pre-1800 Islamicate societies. Without diminishing the pioneering achievements of the generations of historians who have preceded us, and upon whose work we continue to rely, this combined weight has tended a) to marginalize the study of occult sciences in Islamicate societies; b) to emphasize investigations of content from an etic perspective of how we got to the present, which is primarily seen as how the scientific content is connected to the rise of modern science in Europe; and c) to concomitantly marginalize the study of science in post-1200 Islamicate societies, particularly those with little to no connection to the rise of “Western” science. The contributions build upon conversations that took place among participants in December 2019 at a workshop at New York University (NYU), Abu Dhabi Institute in New York City, funded by a grant from NYU Abu Dhabi.

These thinkers, relatively unknown in anglophone scholarship, offer important contributions to contemporary debates in posthumanism and animal studies. Particularly in so far as they scrutinise our often awkward attempts to understand the behaviour of animals in labs and fields – to know what animal bodies can do – they share in the rethinking of interspecies forms (...) of life, as domains of both empirical knowledge and zoo-political performance, and thereby take important steps towards a new philosophical ethology.

We go through life, focusing our attention on many things. But how much do we focus on ourselves? We may be aware of many things, but are we self-aware? This is a question our contemporary culture asks us to consider more and more, and words like "self-awareness," "personal identity," "authenticity," and "mindfulness" are becoming not just buzz-words but virtues. The ancient dictum "know thyself" reverberates in all corners of our lives, from Disney characters on our TVs to DISC profiles at (...) our workplaces. Some of the more mindful members of our society may even be tempted to disdain those who are not as mindful as they are. But what if our self-aware culture, hailing us to pursue our true selves, is unaware of itself? What if our definitions of true and false self-understanding are myopic, slanted towards a narrow solipsism that is actually leading people away from authenticity, while all the while championing it? If so, how would we know? Who is best able to define these things and to teach us how to know ourselves truly?

Vinciane Despret is a Belgian philosopher whose work proposes new questions and approaches to human–animal relations. Of central importance to her thought is an intellectual and cultural proposal to allow animals to show their agency and to be interesting. In scientific research animals are too often reduced to uninteresting, instinctive machines, whereas other modes of engagement allow us to see the wonderfully surprising, culturally rich, and intelligently inventive lives lived by animals. With genuine curiosity, Despret responds that humans and animals (...) transform one another through daily encounters, and she explores these metamorphoses through the history of philosophy, literature, science, field research, and art. In a playful though serious tone, Despret claims that animals are always more interesting than we give them credit for, and that the achievements of animals are never far from our own. (shrink)

To assess Brette's proposal to expunge “coding” from the neuroscientist's lexicon, we must consider its origins. The coding metaphor is due largely to British nerve physiologist Edgar Adrian. I suggest two ways that the coding metaphor fueled his research. I conclude that the debate today should not be about the “truth” of the metaphor but about its continuing utility.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Engaging the Doctrine of Israel: A Christian Israelology in Dialogue with Ongoing Judaism by Matthew LeveringJustin Schembri O.P.Engaging the Doctrine of Israel: A Christian Israelology in Dialogue with Ongoing Judaism by Matthew Levering (Eugene, OR: Cascade, 2021), 547 pp.Engaging the Doctrine of Israel not only presents an interesting take on an old and complex problem but also is intriguing in its basic thesis and overall development. (...) In this book, Levering attempts, and succeeds, to marry a scripturally grounded dialogue with ongoing Judaism with the necessary presuppositions of Christian dogmatics. He does so in order to understand the central realities of God's biblical people Israel and to shine a light on how these realities must inform Christian thought (3).Such a volume fills a gap in research, since Christian dogmatic studies [End Page 1437] often suffer a lack of appreciating just how important understanding "Israel's covenantal life" is for Christian doctrine (3). Thus, while Levering tells us that this book is "the dogmatic sequel" to his Engaging the Doctrine of Marriage (1), the content of the book cannot be divorced from its scriptural foundation, nor from a contemporary dialogue with Israel.After an ample introduction (1–47), Levering begins his treatment of the matter by explaining the necessary hermeneutical framework in which such an engagement can take place (48–109). This foundational chapter not only provides the grounding for the chapters that follow but also examines the pitfalls to avoid in dialoging with ongoing Israel. In particular, Levering finds a balance in the need for both Christians and Jews to retain core beliefs and a recognition that both sides have suffered from unnecessary and painful biases that have hurt dialogue in the past (52–53).Since Levering is writing from the point of view of a Christian, he is right to point out that a healthy and fruitful dialogue with Judaism in the present moment requires both a solid foundation in Christian doctrine and an acknowledgement of how the New Testament has been misused to reject and subject the Jewish people to injustice over the centuries. Thus, in agreement with the author, I too think that Christian–Jewish dialogue plays a vital role not only in healing such biases but also in bridging needless gaps between the two groups (108–109).This crucial chapter is followed by an examination of six different areas (110–443) in which Levering engages with Israel's doctrine through a Christian lens. In each case, a similar format is found in the sense that Levering first introduces the topic and then engages with different Jewish and Christian scholars in order to elicit a more robust space for dialogue to happen. Each topic of study, then, is brought to a conclusion wherein Levering explicates both the pitfalls to be avoided and what truth can Christians glean.The first area to be discussed is creation (110–46). In this chapter, Levering examines why is it important for both Jews and Christians alike to affirm that omnipotent God created creation ex nihilo. The author is right to point out that if God did not create creation out of nothing, then God is not omnipotent but rather merely a "powerful finite being" (111).While I would have like to see a more robust exegetical analysis on Gen 1:1–2 (especially with regards to bǝrē'šît, since it is not so certain that this prepositional phrase should be interpreted temporally), the author is right to move beyond the metaphysical question of creation ex nihilo, to point out that creation is "also rooted in God's speaking, and thus his Word," since creation must be understood as the way in which God establishes "a dialogic communion" (124) with creation. After all, it is the Word which is [End Page 1438] fundamental; God speaks and practically invites creation to take its place amongst the grooves that God has made.What is more is that this Word, as Levering acknowledges, is both divine and human, since it is the Word of God written in human language. Thus, in Scripture, we cannot escape the "divine–human collaboration" (145) that is willed by... (shrink)

In modal subordination, a modal sentence is interpreted relative to a hypothetical scenario introduced in an earlier sentence. In this paper, I argue that this phenomenon reflects the fact that the interpretation of modals is an ANAPHORIC process. Modal morphemes introduce sets of possible worlds, representing alternative hypothetical scenarios, as entities into the discourse model. Their interpretation depends on evoking sets of worlds recording described and reference scenarios, and relating such sets to one another using familiar notions of restricted, preferential (...) quantification. This proposal relies on an extended model of environments in dynamic semantics to keep track of associations between possible worlds and ordinary individuals; it assumes that modal meanings and other lexical meanings encapsulate quantification over possible worlds. These two innovations are required in order for modals to refer to sets of possible worlds directly as static objects in place of the inherently dynamic objects—quite different from the referents of pronouns and tenses—used in previous accounts. The simpler proposal that results offers better empirical coverage and suggests a new parallel between modal and temporal interpretation. (shrink)

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)

We present an algorithm for simultaneously constructing both the syntax and semantics of a sentence using a Lexicalized Tree Adjoining Grammar (LTAG). This approach captures naturally and elegantly the interaction between pragmatic and syntactic constraints on descriptions in a sentence, and the inferential interactions between multiple descriptions in a sentence. At the same time, it exploits linguistically motivated, declarative specifications of the discourse functions of syntactic constructions to make contextually appropriate syntactic choices.

This paper develops a general approach to contextual reasoning in natural language processing. Drawing on the view of natural language interpretation as abduction (Hobbs et al., 1993), we propose that interpretation provides an explanation of how an utterance creates a new discourse context in which its interpreted content is both true and promi- nent. Our framework uses dynamic theories of semantics and pragmatics, formal theories of context, and models of attentional state. We describe and illustrate a Prolog implementation.

In lieu of an abstract, here is a brief excerpt of the content:Lack, Perversion, ShameJustin Garson, PhD (bio)I am extremely grateful to the commentators for giving me so much food for thought. Space considerations prevent me from engaging with all of the interesting points they raise, or responding at the length they warrant. For that reason, I chose to structure my response in terms of three recurring themes or distinctions: lack/perversion, madness/mental illness, and shame/pride. Hopefully, the philosophical richness of the (...) commentaries has already indicated the fruitfulness of returning, anew, to the Late Modern distinction between madness and idiocy.Lack and PerversionSeveral commentators directly challenge my characterization of the distinction between idiocy and madness as one between a lack, and a perversion, of the ordinary powers of reason.On the one hand, commentators point to the extent to which Late Modern theorists of madness still frame madness in terms of a lack, rather than a positive being. Jeppsson points out correctly that the Late Modern theorist still insists that madness stems from a lack of some sort or another: “one lacks proper premises to draw conclusions from, lacks a proper appreciation of reality.” Madness is not merely a different mode of reasoning about the world, but one that issues from a certain absence. Kusters, similarly, points out that the projects of Locke and Heinroth “remain insufficient because they remain focused on the mad as lacking something…a lack that prevents them from being part of the communal,” although he thinks Kant’s Aberwitz comes closest to a genuinely positive account. Tsou minimizes the relevance of the distinction between madness and idiocy by pointing out that both represent deviations from (hence they both “lack”) “normal psychological reason.”On the other hand, Banicki points out that even to construe madness in terms of a “lack” or “failure” (a failure of function, of reason, of action) is to presume, at least indirectly, a positive account of madness: after all, the mad person can only properly be said to “fail” in the exercise of their reason because they are the sort of being that participates in reason. A tree or a stone cannot be said to “fail” in the exercise of its reason (as Gipps puts it, “a baobab cannot jump to conclusions”). These commentators have helped me to clarify and sharpen the distinction between lack and perversion and the way they intersect with the categories of idiocy and madness.To put my view summarily: idiocy is, in its essence, just a way of lacking reason, in the same way that being poor is, in its essence, just a way of lacking wealth. But madness is not, in its essence, [End Page 327] a way of lacking reason. It is a way of exercising reason, but via perversion, where perversion must be understood as having the resonance both of excessive and also of driving toward an unexpected end.As I indicated in the paper, the distinction between lack and perversion is easiest to think about in terms of sexuality. A person may lack sexual desire: They may find themselves for long stretches of time with little to no desire for sex, the absence of sexual fantasies, and the inability to stimulate themselves or be stimulated by others. Crucially, being devoid of sexual desire is not a way of being sexual, any more than being dead is a way of being alive, or being a fish a way of being a mammal. By contrast, having a meager sexual desire is a way of being sexual, but via a lack or diminution: It is a way of not having much of it around.In contrast, one can have what is called a “perverse” sexuality: Sexuality infused with the desire to dominate, or be dominated, or to be watched from afar, or to couple with beasts or machines. This is a way of being sexual; it is even a kind of rampant sexuality. One talks of “harnessing” their sexuality, “restraining” it, “unleashing” it. For some, perversions may be terrifying to contemplate, almost unthinkable, even revolting. For others perversion is ecstatic; it transports one to another world in which one sees everything differently; the one who exercises her perversions morphs into an... (shrink)

I show how a conversational process that takes simple, intuitively meaningful steps may be understood as a sophisticated computation that derives the richly detailed, complex representations implicit in our knowledge of language. To develop the account, I argue that natural language is structured in a way that lets us formalize grammatical knowledge precisely in terms of rich primitives of interpretation. Primitives of interpretation can be correctly viewed intentionally, as explanations of our choices of linguistic actions; the model therefore fits our (...) intuitions about meaning in conversation. Nevertheless, interpretations for complex utterances can be built from these primitives by simple operations of grammatical derivation. In bridging analyses of meaning at semantic and symbol‐processing levels, this account underscores the fundamental place for computation in the cognitive science of language use. (shrink)

The meanings of donkey sentences cannot be captured using a procedure which, like Montague’s, uses the existential quantifiers of classical logic to translate indefinites and the variables to translate pronouns. The treatment of these examples requires meanings which depend on the context in which sentences appear, and thus necessitates a logic which models this context to some extent. If context is represented as the information conveyed in discourse, and the meanings of pronouns are enriched to depend on this information, the (...) result is the E-Type approach (ETA) adapted by Heim (1990) from proposals in Evans (1980) and Cooper (1979). If the context is represented as a list of potential referents, and the meanings of indefinites are enriched to introduce new referents into this list, the result is a compositional formulation like Groenendijk and Stokhof’s (1990) of the discourse representation theory (DRT) of Kamp (1981) and Heim (1982). Either tack suffices to capture the way in which the referents of he and it systematically correspond to the alternative possibilities described by the antecedent. Disjunction offers a parallel way of introducing alternatives in the antecedent of a conditional, as shown in (2). (shrink)

In demonstration, speakers use real-world activity both for its practical effects and to help make their points. The demonstrations of origami mathematics, for example, reconfigure pieces of paper by folding, while simultaneously allowing their author to signal geometric inferences. Demonstration challenges us to explain how practical actions can get such precise significance and how this meaning compares with that of other representations. In this paper, we propose an explanation inspired by David Lewis’s characterizations of coordination and scorekeeping in conversation. In (...) particular, we argue that words, gestures, diagrams and demonstrations can function together as integrated ensembles that contribute to conversation, because interlocutors use them in parallel ways to coordinate updates to the conversational record.

This book is a significant accomplishment, and for now the most comprehensive intervention in a debate that has been more than three hundred years in the making. At least since Pierre Bayle, commentators have imagined a sort of paradox in the pairing of Spinoza’s irreproachable way of life with his scandalous philosophy, in contrast with the perfect fit between Leibniz’s optimism for the status quo with his supposedly opportunistic relation to his courtly benefactors. Together with these biographical coordinates, to which (...) Lærke’s work is attentive and sensitive, there is a philosophical opposition that is supposed to be absolute: each philosopher is the other’s perfect opposite. Matthew Stewart’s bestseller The Courtier and the Heretic is the latest iteration of this myth, and Lærke’s study might best be summed up as the perfect antidote to Stewart’s: it is a rigorous, dense, and, most importantly, a just treatment of the authors themselves, whose own words often belie the roles in which they would posthumously be cast. While Lærke acknowledges that there is indeed an easy opposition one can construct between the major metaphysical commitments of the two thinkers, he nonetheless wants to know how their systematic differences might have grown out of an intense engagement on Leibniz’s part with a philosophy he indeed ended up opposing, yet against which he felt compelled to articulate his own views, and back to which he often seemed in danger of returning.
