In this paper, new evidence is presented for the assumption that the reason-relation reading of indicative conditionals ('if A, then C') reflects a conventional implicature. In four experiments, it is investigated whether relevance effects found for the probability assessment of indicative conditionals (Skovgaard-Olsen, Singmann, and Klauer, 2016a) can be classified as being produced by a) a conversational implicature, b) a (probabilistic) presupposition failure, or c) a conventional implicature. After considering several alternative hypotheses and the accumulating evidence from other studies as (...) well, we conclude that the evidence is most consistent with the Relevance Effect being the outcome of a conventional implicature. This finding indicates that the reason-relation reading is part of the semantic content of indicative conditionals, albeit not part of their primary truth-conditional content. (shrink)

In this paper, a novel experimental task is developed for testing the highly influential, but experimentally underexplored, possible worlds account of conditionals (Stalnaker, 1968; Lewis, 1973). In Experiment 1, this new task is used to test both indicative and subjunctive conditionals. For indicative conditionals, five competing truth tables are compared, including the previously untested, multi-dimensional possible worlds semantics of Bradley (2012). In Experiment 2, these results are replicated and it is shown that they cannot be accounted for by an alternative (...) hypothesis proposed by our reviewers. In Experiment 3, individual variation in truth assignments of indicative conditionals is investigated via Bayesian mixture models that classify participants as following one of several competing models. As a novelty of this study, it is found that a possible worlds semantics of Lewis and Stalnaker is capable of accounting for participants’ aggregate truth value assignments in this task. Applied to indicative conditionals, we show across three experiments, that the theory both captures participants’ truth values at the aggregate level (Experiments 1 and 2) and that it makes up the largest subgroup in the analysis of individual variation in our experimental paradigm (Experiment 3).

The fields of machine learning (ML) and cognitive science have developed complementary approaches to computationally modeling human behavior. ML's primary concern is maximizing prediction accuracy; cognitive science's primary concern is explaining the underlying mechanisms. Cross-talk between these disciplines is limited, likely because the tasks and goals usually differ. The domain of e-learning and knowledge acquisition constitutes a fruitful intersection for the two fields’ methodologies to be integrated because accurately tracking learning and forgetting over time and predicting future performance based on (...) learning histories are central to developing effective, personalized learning tools. Here, we show how a state-of-the-art ML model can be enhanced by incorporating insights from a cognitive model of human memory. This was done by exploiting the predictive performance equation's (PPE) narrow but highly specialized domain knowledge with regard to the temporal dynamics of learning and forgetting. Specifically, the PPE was used to engineer timing-related input features for a gradient-boosted decision trees (GBDT) model. The resulting PPE-enhanced GBDT outperformed the default GBDT, especially under conditions in which limited data were available for training. Results suggest that integrating cognitive and ML models could be particularly productive if the available data are too high-dimensional to be explained by a cognitive model but not sufficiently large to effectively train a modern ML algorithm. Here, the cognitive model's insights pertaining to only one aspect of the data were enough to jump-start the ML model's ability to make predictions—a finding that holds promise for future explorations.

A valuable resource for sex researchers as well as undergraduate courses in the philosophy of sex.

Alain Locke, an often neglected classical American Pragmatist, developed a pluralistic value theory as an antidote to the "value absolutism" he considered the root cause of social conflict. Values, for Locke, are not immutable features of a transcendent reality, but rather emerge from human functional attitudes, or what he calls "feeling-modes." However incommensurable the contextualized values of diverse cultures may appear, they can always be traced back to common modes of valuing. Recognizing the common character of our human faculty of (...) valuation allows us to see a basic functional equivalence among superficially conflicting values, thus undermining value absolutism. This paper suggests that one reason the debate over same-sex marriage in the United States has persisted is that the arguments have been advanced primarily in absolute value terms. Re-casting the debate in terms of a Lockean pluralistic value dialogue suggests a path out of the stalemate. (shrink)

In an attempt to improve upon Alexander Pruss’s work (The principle of sufficient reason: A reassessment, pp. 240–248, 2006), I (Weaver, Synthese 184(3):299–317, 2012) have argued that if all purely contingent events could be caused and something like a Lewisian analysis of causation is true (per, Lewis’s, Causation as influence, reprinted in: Collins, Hall and paul. Causation and counterfactuals, 2004), then all purely contingent events have causes. I dubbed the derivation of the universality of causation the “Lewisian argument”. The (...) Lewisian argument assumed not a few controversial metaphysical theses, particularly essentialism, an incommunicable-property view of essences (per Plantinga’s, Actualism and possible worlds, reprinted in: Davidson (ed.) Essays in the metaphysics of modality, 2003), and the idea that counterfactual dependence is necessary for causation. There are, of course, substantial objections to such theses. While I think a fight against objections to the Lewisian argument can be won, I develop, in what follows, a much more intuitive argument for the universality of causation which takes as its inspiration a result from Frederic B. Fitch’s work (J Symb Logic 28(2):135–142, 1963) [with credit to who we now know was Alonzo church’s, Referee Reports on Fitch’s Definition of value, in: (Salerno (ed.), New essays on the knowability paradox, 2009)] that if all truths are such that they are knowable, then (counter-intuitively) all truths are known. The resulting Church–Fitch proof for the universality of causation is preferable to the Lewisian argument since it rests upon far weaker formal and metaphysical assumptions than those of the Lewisian argument.

The structure of people’s conceptual knowledge of concrete nouns has traditionally been viewed as hierarchical (Collins & Quillian, 1969). For example, superordinate concepts (vegetable) are assumed to reside at a higher level than basic‐level concepts (carrot). A feature‐based attractor network with a single layer of semantic features developed representations of both basic‐level and superordinate concepts. No hierarchical structure was built into the network. In Experiment and Simulation 1, the graded structure of categories (typicality ratings) is accounted for by the (...) flat attractor network. Experiment and Simulation 2 show that, as with basic‐level concepts, such a network predicts feature verification latencies for superordinate concepts (vegetable ). In Experiment and Simulation 3, counterintuitive results regarding the temporal dynamics of similarity in semantic priming are explained by the model. By treating both types of concepts the same in terms of representation, learning, and computations, the model provides new insights into semantic memory. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:The Sacrificial Ram and the Swan QueenMimetic Theory Fades to BlackBrian Collins (bio)“We speak of a ‘black’ mirror. But where it mirrors, it darkens, of course, but it doesn’t look black, and that which is seen in it does not appear ‘dirty’ but ‘deep.’”—Ludwig Wittgenstein, Remarks on ColorThis paper explores the ways in which male and female bodies become the sites of mimetic desire and ritual violence in (...) Darren Aronofsky’s two companion films The Wrestler (109 min, Wild Bunch, 2008, DVD) and Black Swan (108 min, Fox Searchlight, 2010, DVD). Both films (which were originally intended to be one film, explaining their thematic consistency)1 share three elements. First, both explore cultural forms, wrestling and dance, respectively, that punish the body of the performer in a spectacular way. Second, both films end with the ritualistic dying (if not the death) of the main character. Third, in both films, this dying is accompanied by a kind of transformation that can only be called “becoming-animal.”2 Though this last point is much easier to demonstrate [End Page 207] in the case of Black Swan, I will argue that this is also true for The Wrestler. In interpreting these films, I will rely mainly on René Girard’s ideas about mimetic desire and the surrogate victim mechanism, supplemented by Slavoj Žižek’s notion of symbolic death. Symbolic death or “second death” is Žižek’s Hegelian appropriation of the psychoanalytic death drive. The death drive holds a special place for Girard, since he considers Freud’s formulation of the death drive his admission that the Oedipal complex cannot explain the compulsion to repetition, an admission for which he credits Freud’s honesty. In this paper, I demonstrate that pseudo-masochism, Girard’s alternate theory of repetition, and the Žižekian second death are both present in Black Swan and The Wrestler, and that each film plays on the animal/human distinction and ritual transformations of the body to explore these themes.Part One: The Sacrificial Ram“The function of the wrestler is not to win: it is to go exactly through the motions which are expected of him.”—Roland Barthes, “The World of Wrestling,” MythologiesThe Pseudo-Masochistic Body I: Becoming-RamWilliam Golding’s novel Pincher Martin: The Two Deaths of Christopher Martin (London: Faber and Faber Limited, 1956) follows a bitter, selfish, and intransigent sailor who finds himself clinging to a rock in the middle of the ocean, the sole survivor of a shipwreck, only to slowly learn that he is not a survivor at all, but is rather trapped like a character from The Twilight Zone in the utter loneliness of the timeless time between his titular “two deaths.” The first death comes when Martin goes down with his ship and the second comes when he is annihilated (possibly; the ending is ambiguous) by the “black lightning,” which Terry Eagleton identifies in his analysis of the book as “the fire of God’s ruthless love, which burns up those who cannot bear it.” Martin’s misotheism is his last defense against the terrifying power of love, and he continues to defy God as the black lightning engulfs him.3 Why the two deaths? Martin is unable to die properly the first time, Eagleton argues, “because he is incapable of love. Only the good are capable of dying. Martin cannot yield himself up to death because he has never been able to yield himself up to others in life.”4 [End Page 208]Randy “The Ram” Robinson, born Robin Ramzinski, (Mickey Rourke), the protagonist of The Wrestler, is, like Pincher Martin, between two deaths, isolated from the rest of humanity because of his inability to connect with others. But while Pincher Martin is defiant and bound for a self-created Hell because of his deliberate rejection of love, Ram is a much more sympathetic character—though no less doomed—because he tries but fails time after time to accept the love of those who could save him. Pincher Martin’s self-created internal obstacle is his hatred of God, externalized through his encounter with the black lightning. But in Ram’s case... (shrink)

Crazily, Christopher Norris seems to think sociology is at war with philosophy; it is not. I respond to his hostile comments on the sociology of scientific knowledge, which was inspired by Wittgenstein, by explaining the need for symmetry in the explanation of scientific knowledge, methodological relativism, elective modernism and a number of other issues.

An original argument about how scientific models often times distort reality rather than accurately reflect it. And it's this distortion that often gives scientific models their epistemic power.

This study takes inquiry as the starting point for epistemological theorising. It uses this idea to develop new and systematic answers to some of the most fundamental questions in epistemology, including about the nature of core epistemic phenomena as well as their value and the extent to which we possess them.

The coherence objection to the doctrine of the Incarnation maintains that it is impossible for one individual to have both the attributes of God and the attributes of a human being. This article examines Thomas Aquinas’s answer to this objection. I challenge the dominant, mereological interpretation of Aquinas’s position and, in light of this challenge, develop and defend a new alternative interpretation of Aquinas’s response to this important objection to Christian doctrine.

Assertion is the central vehicle for the sharing of knowledge. Whether knowledge is shared successfully often depends on the quality of assertions: good assertions lead to successful knowledge sharing, while bad ones don't. In Sharing Knowledge, Christoph Kelp and Mona Simion investigate the relation between knowledge sharing and assertion, and develop an account of what it is to assert well. More specifically, they argue that the function of assertion is to share knowledge with others. It is this function that supports (...) a central norm of assertion according to which a good assertion is one that has the disposition to generate knowledge in others. The book uses this functionalist approach to motivate further norms of assertion on both the speaker and the hearer side and investigates ramifications of this view for other questions about assertion.

The ethics of autonomous cars and automated driving have been a subject of discussion in research for a number of years :28–58, 2016). As levels of automation progress, with partially automated driving already becoming standard in new cars from a number of manufacturers, the question of ethical and legal standards becomes virulent. For exam-ple, while automated and autonomous cars, being equipped with appropriate detection sensors, processors, and intelligent mapping material, have a chance of being much safer than human-driven cars in (...) many regards, situations will arise in which accidents cannot be completely avoided. Such situations will have to be dealt with when programming the software of these vehicles. In several instances, internationally, regulations have been passed, based on legal considerations of road safety, mostly. However, to date, there have been few, if any, cases of a broader ethics code for autonomous or automated driving preceding actual regulation and being based on a broadly composed ethics committee of independent experts. In July 2016, the German Federal Minister of Transport and Digital Infrastructure, Alexander Dobrindt, appointed a national ethics committee for automated and connected driving, which began its work in September 2016. In June 2017, this committee presented a code of ethics which was published in German and in English. It consists of 20 ethical guidelines. Having been a member of this committee, I will present the main ethical topics of these guidelines and the discussions that lay behind them. (shrink)

In this essay, I argue that a proper understanding of the historicity of love requires an appreciation of the irreplaceability of the beloved. I do this through a consideration of ideas that were first put forward by Robert Kraut in “Love De Re” (1986). I also evaluate Amelie Rorty's criticisms of Kraut's thesis in “The Historicity of Psychological Attitudes: Love is Not Love Which Alters Not When It Alteration Finds” (1986). I argue that Rorty fundamentally misunderstands Kraut's Kripkean analogy, and (...) I go on to criticize her claim that concern over the proper object of love should be best understood as a concern over constancy. This leads me to an elaboration of the distinct senses in which love can be seen as historical. I end with a further defense of the irreplaceability of the beloved and a discussion of the relevance of recent debates over the importance of personal identity for an adequate account of the historical dimension of love.

A prominent approach to scientific explanation and modeling claims that for a model to provide an explanation it must accurately represent at least some of the actual causes in the event's causal history. In this paper, I argue that many optimality explanations present a serious challenge to this causal approach. I contend that many optimality models provide highly idealized equilibrium explanations that do not accurately represent the causes of their target system. Furthermore, in many contexts, it is in virtue of (...) their independence of causes that optimality models are able to provide a better explanation than competing causal models. Consequently, our account of explanation and modeling must expand beyond the causal approach. (shrink)

In “A Tension in the Strong Program: The Relation between the Rational and the Social”, Shahram Shahryari (2021) advances the following thesis: In his Strong Program in the sociology of science, David Bloor blames traditional philosophy of science for adopting a dualist strategy in explaining scientific developments, as it employs rational explanation for successful science and social explanation for flawed science. Instead, according to Bloor, all scientific developments should be explained monistically, i.e. in terms of social causes. This is also (...) referred to as the Symmetry Principle, and it is a key tenet in the Strong Program. The author detects a tension here, as Bloor apparently asserts that traditional philosophy of science deploys two kinds of explanation, and simultaneously insists that there is only one kind, i.e. social explanation.

This handbook article gives a critical overview of recent discussions of epistemic authority. It favors an account that brings into balance the dictates of rational deference with the ideals of intellectual self-governance. A plausible starting point is the conjecture that neither should rational deference to authorities collapse into total epistemic submission, nor the ideal of mature intellectual self-governance be conflated with (illusions of) epistemic autarky.

A plausible thought about vagueness is that it involves semantic incompleteness. To say that a predicate is vague is to say (at the very least) that its extension is incompletely specified. Where there is incomplete specification of extension there is indeterminacy, an indeterminacy between various ways in which the specification of the predicate might be completed or sharpened. In this paper we show that this idea is bound to founder by presenting an argument to the effect that there are vague (...) predicates which cannot be sharpened in such a way as to meet certain basic constraints (of penumbral connection and public accessibility) that must be imposed on the very notion of a sharpening.

Many accounts of scientific modelling assume that models can be decomposed into the contributions made by their accurate and inaccurate parts. These accounts then argue that the inaccurate parts of the model can be justified by distorting only what is irrelevant. In this paper, I argue that this decompositional strategy requires three assumptions that are not typically met by our best scientific models. In response, I propose an alternative view in which idealized models are characterized as holistically distorted representations that (...) are justified by allowing for the application of various modelling techniques.

Suppose you ask yourself whether your father's record collection includes a certain recording of The Trout and venture to find out. At that time, you embark on an inquiry into whether your father owns the relevant recording. Your inquiry is a project with a specific goal: finding out whether your father owns the recording. This fact about your inquiry generalizes: inquiry is a goal-directed enterprise. A specific inquiry can be individuated by the question it aims to answer and by who (...) aims to answer the question. Your inquiry into whether your father owns the recording differs from your inquiry into how many records your father owns because different questions are being asked. Your inquiry into whether your father owns the recording differs from my inquiry into whether he does because different people are inquiring. The goal of inquiry into a given question by an agent, α, can be characterized, neutrally, as α's having the answer to that question. I will here focus only on inquiries into whether questions and characterize the goal of inquiry into whether φ by α as α's having the answer to the question whether φ. (shrink)

Christopher Hookway presents a series of essays on the work of Charles Sanders Peirce (1839-1913), the 'founder of pragmatism' and one of the most important and original American philosophers.

In this paper, I first argue against various attempts to justify idealizations in scientific models that explain by showing that they are harmless and isolable distortions of irrelevant features. In response, I propose a view in which idealized models are characterized as providing holistically distorted representations of their target system. I then suggest an alternative way that idealized modeling can be justified by appealing to universality.

How does good combine with bad? Most creatures are neither so blessed as to only enjoy good nor so cursed as to only suffer bad. Rather, the good and bad they receive throughout their lives combine to produce their overall quality of life. But it’s not just whole lives that have combined good and bad. Many stretches within contain both positive and negative occurrences whose value is joined to form the overall quality of that span of time. In a single (...) morning someone might wake up, brush their teeth, stub their toe groggily lumbering down the stairs, and have a sip of coffee that’s tasty but so hot they burn their tongue. These events are good and bad for them to various degrees, and their value comes together to form an overall value for them of that morning. A single moment, even, can have combined value from distinct pockets of good and bad that occur simultaneously. The tastiness of the coffee is good, but the pain of the heat is bad. They combine to form an overall value of the sipping moment – negative if the pain outweighed the flavor. Thus, wellbeing and illbeing combine. But how? How can someone rightly chastise themselves for sipping the overly hot coffee when it was, in fact, good because it was tasty? To pose the question starkly, a life can be bad, even so bad to not be worth living, and yet it can have many instances of good, where these goods are, in themselves, pure of any negativity. But how can good make something bad? (shrink)

This paper is built around a single, simple idea. It is widely agreed that there is a distinctive kind of awareness each of us has of his own bodily actions. This action-awareness is different from any perceptual awareness a subject may have of his own actions; it can exist in the absence of such perceptual awareness. The single, simple idea around which this paper is built is that the distinctive awareness that subjects have of their own mental actions is a (...) form of action-awareness. Subjects’ awareness of their own mental actions is a species of the same genus that also includes the distinctive awareness of bodily actions. More specifically, I claim. (shrink)

BioShock begins simply with the text “1960 Mid‐Atlantic.” The player's horizon shifts to accommodate this fact, like not being so surprised that Jack can smoke in the airplane. What follows in BioShock is the development of a narrative where it is assumed that Jack is entering Rapture for the first time in his life. Later, it is revealed that he is not. When Andrew Ryan exposes Jack's real identity, Ryan is falsifying both the narrative of Jack coming to Rapture for (...) the first time and the meta‐narrative of the player operating a free agent as an avatar. Understanding how BioShock effectively manipulates players will take us through a variety of territories: cognitive science, philosophy of mind, philosophical hermeneutics, philosophy of video gaming, and philosophy of free will. It's all a testament to the brilliance of BioShock and a demonstration of how video games can teach us‐ even change us. (shrink)

Intersectionality has attracted substantial scholarly attention in the 1990s. Rather than examining gender, race, class, and nation as distinctive social hierarchies, intersectionality examines how they mutually construct one another. I explore how the traditional family ideal functions as a privileged exemplar of intersectionality in the United States. Each of its six dimensions demonstrates specific connections between family as a gendered system of social organization, racial ideas and practices, and constructions of U.S. national identity.

Conditionalization is a widely endorsed rule for updating one’s beliefs. But a sea of complaints have been raised about it, including worries regarding how the rule handles error correction, changing desiderata of theory choice, evidence loss, self-locating beliefs, learning about new theories, and confirmation. In light of such worries, a number of authors have suggested replacing Conditionalization with a different rule — one that appeals to what I’ll call “ur-priors”. But different authors have understood the rule in different ways, and (...) these different understandings solve different problems. In this paper, I aim to map out the terrain regarding these issues. I survey the different problems that might motivate the adoption of such a rule, flesh out the different understandings of the rule that have been proposed, and assess their pros and cons. I conclude by suggesting that one particular batch of proposals, proposals that appeal to what I’ll call “loaded evidential standards”, are especially promising. (shrink)

Deference principles are principles that describe when, and to what extent, it’s rational to defer to others. Recently, some authors have used such principles to argue for Evidential Uniqueness, the claim that for every batch of evidence, there’s a unique doxastic state that it’s permissible for subjects with that total evidence to have. This paper has two aims. The first aim is to assess these deference-based arguments for Evidential Uniqueness. I’ll show that these arguments only work given a particular kind (...) of deference principle, and I’ll argue that there are reasons to reject these kinds of principles. The second aim of this paper is to spell out what a plausible generalized deference principle looks like. I’ll start by offering a principled rationale for taking deference to constrain rational belief. Then I’ll flesh out the kind of deference principle suggested by this rationale. Finally, I’ll show that this principle is both more plausible and more general than the principles used in the deference-based arguments for Evidential Uniqueness. (shrink)
