In this paper, we contrast the different ways in which the representationalist and the attitudinalist in the theory of emotions account for the fact that emotions have evaluative correctness conditions. We argue that the attitudinalist has the resources to defend her view against recent attacks from the representationalist. To this end, we elaborate on the idea that emotional attitudes have a rich profile and explain how it supports the claim that these attitudes generate the wished-for evaluative correctness (...) conditions. Our argument rests on the idea that emotional attitudes manifest a sensitivity to evaluative evidence and that this sensitivity secures the kind of normativity we expect of the emotions. We bring our discussion to a close by assessing whether the psychological underpinnings of this sensitivity to evaluative evidence are such as to threaten the foundation of attitudinalism: the idea that emotions do not represent values. Given the available models of how we might access values prior to emotional experience, we conclude that the attitudinalist is still in the game. (shrink)

Nominalists need some account of correctness for sentences committed to the existence of abstract objects. This paper proposes a new statement of such conditions specifically for properties. The account builds on an earlier proposal of mine, but avoids the counter-examples against the latter pointed out by Thomas Schindler, particularly, the sentence ‘There are inexpressible properties’. I argue that the new proposal is independently motivated and more faithful to the spirit of the kind of error-theoretic nominalism that the original (...) proposal was part of. Along the way, I also propose novel treatments of Arthur Pap’s and W.V.O. Quine’s notoriously hard-to-paraphrase sentences about abstracta. (shrink)

In the second Critique, Kant claims that the moral law is given as a fact of reason. In this paper, contra the standard view, I argue that there is a non-dogmatic way of defending this claim. And Kant’s principle of morality is widely taken to be a formal principle. How then can such a formal principle be reconciled with our substantial moral end? In this paper, I also argue that Kant’s principle of morality can be construed as a formal principle (...) in the sense that it provides correctness conditions for moral laws, rather than providing specific moral laws.Dans sa deuxième Critique, Kant affirme que la loi morale se donne comme un fait de raison. Dans cet article, contrairement à la position standard, nous prétendons qu’il existe une autre façon — non dogmatique — de défendre cette affirmation. Par ailleurs, le principe de moralité de Kant est largement considéré comme étant formel. Comment un tel principe formel peut-il être réconcilié avec notre fin morale substantielle? Nous soutenons également que le principe de moralité de Kant peut être interprété comme un principe formel dans le sens où il fournit des conditions d’acceptabilité pour les lois morales, et non des lois morales spécifiques.

The traditional metaethical distinction between cognitivist absolutism,on the one hand, and speaker relativism or noncognitivism, on the other,seemed both clear and important. On the former view, moral judgmentswould be true or false independently on whose judgments they were, andmoral disagreement might be settled by the facts. Not so on the latter views. But noncognitivists and relativists, following what Simon Blackburn has called a “quasi-realist” strategy, have come a long way inmaking sense of talk about truth of moral judgments and itsindependence (...) of moral judges and their attitudes or standards. Thesuccess of this strategy would undermine the traditional way of understanding the distinction, and it is not obvious how it can be reformulated. In this paper, I outline the difficulty posed by quasi-realism, raise problems for some prior attempts to overcome it, and present my own suggestion, focusing on correctness conditions that are internal to the act of moral judgment.

In this paper, the author addresses the problem of socialisation of children with a history of disabilities and mental retardation by means of visual arts. It is important to look at the very sphere of life of these categories of children. As a rule, these children, for the most part, live in dysfunctional families, which makes it almost impossible to provide them with a form of socialization. This article focuses on the extent to which and how a programme of socialisation (...) of these children can be achieved through the medium of visual arts. At the moment there are works of modern pedagogues who have devoted their scientific researches to this problem, but there are few teachers-artists who deal with this problem. In this article the author devotes his creative attention to this issue and reflects on what means of fine arts and visual literacy can develop and guide in the right direction the socialization of children and young people with disabilities by means of fine arts. A number of scientific works devoted to this problem are seriously reviewed. The author is actively trying to draw the attention of the teaching community to the problem of prevailing social conditions, to reach an educational and cognitive level and, as a consequence, to a better product of the set task of socialization of children with special needs and disabilities in the learning process by means of subject disciplines: drawing, painting, composition, printmaking, etc. (shrink)

Since the UN Guiding Principles on Business and Human Rights were adopted by the UN Human Rights Council in 2011, they have diffused into policy frameworks, laws, and regulations across the globe. This special issue seeks to advance the interdisciplinary field of human rights research by examining key elements of the emerging transnational regime for the regulation of business and human rights. In seven original contributions, scholars from political science, law, accounting, and philosophy critically reflect on the theoretical foundations of (...) the UNGPs, they analyze the effectiveness of implementation mechanisms and current regulatory practice, and they advance proposals for the future development of the business and human rights regime. In this introduction, we prepare the ground for these analyses, proceeding in three steps. Firstly, we argue that the adoption of the UNGPs has triggered a norm cascade which requires a distinctive, empirically oriented research agenda focusing on the scope, governance, and effectiveness of corporate human rights accountability norms and instruments. Secondly, we explain how the articles in this special issue contribute to that research agenda by addressing these themes. Thirdly, we provide an overview of the individual contributions and point out avenues for future research. (shrink)

In my paper “On the Probabilities of Conditionals,” I claimed, mistakenly, that David Lewis’s four triviality results and Alan Hájek’s proof depend on the application of the following principle to conditionals containing nested conditionals.

Stroud has argued for many years that skepticism is conditionally correct. We cannot, he claims, both undergo a Cartesian-style examination of the extent of our knowledge as well as avoid skepticism. One reason Stroud's position appears quite plausible is the so-called "totality condition" imposed for this kind of examination: as inquiring philosophers we are called upon to assess all of our knowledge, all at once. However, in this paper I argue that Stroud's apparent understanding of the totality condition is mistaken. (...) Evidently, Stroud thinks that honoring the totality condition amounts to imposing the strong requirement that we initially assume that we don't know anything about external reality. However, there is a weaker requirement available: that we initially not assume that we know anything about external reality. I argue i) that the weaker conception of the totality condition is most suitable for the kind of philosophical examination that Stroud seems to have in mind; and ii) that according to this same conception skepticism is not conditionally correct.

I argue for the distinction between presuming that p and maintaining that presumably p. In order to make sense of this distinction, I defend a non-inferentialist conception of presumptions and offer an account of the correctness conditions for both presumptions and presumptive inferences. I characterize presumptions as a type of constative speech-act having certain semantic correctness conditions. In turn, regarding presumptive inferences, my strategy is to provide the correctness conditions for the use of an (...) epistemic modal such as “presumably.” This epistemic modal is characterized as a force indicator for speech-acts of concluding in complex speech-acts of arguing involving presumptive inferences.

John MacFarlane defends a radical form of truth relativism that makes the truth of assertions relative not only to contexts of utterance but also to contexts of assessment, or perspectives. Making sense of assessment-sensitive truth is a matter of making sense of the normative commitments undertaken by speakers in using assessment sensitive sentences. This paper argues against the possibility of making sense of such a practice. Evans raised a challenge to the coherence of relative truth. A modification of the challenge (...) can be given against MacFarlane’s revised views on assertion. The main objection to the relativist is that rational and earnest speakers are not bound by assessment-relative standards of correctness. (shrink)

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

This study examined the efficacy of corrected feedback for improving consent recall throughout the course of an ongoing longitudinal study. Participants were randomly assigned to either a corrected feedback or a no-feedback control condition. Participants completed a consent quiz 2 weeks after consenting to the host study and at months 1, 2, and 3. The corrected feedback group received corrections to erroneous responses and the no-feedback control group did not. The feedback group displayed significantly greater recall overall and in specific (...) content areas. Results support the use of corrected feedback for improving consent recall. (shrink)

In this paper I present reasons for us to accept the hypothesis that suspended judgment has correctness conditions, just like beliefs do. Roughly put, the idea is that suspended judgment about p is correct when both p and ¬p might be true in view of certain facts that characterize the subject’s situation. The reasons to accept that hypothesis are broadly theoretical ones: it adds unifying power to our epistemological theories, it delivers good and conservative consequences, and it allows (...) us to assess processes of reasoning involving attitudes of suspended judgment.

According to the normativists, dispositionalist theories of meaning fail because meaning is normative, not descriptive. One way to understand this notion of normativity is in terms of semantic correctness conditions. Anti-normativists typically accept that meaning implies semantic correctness but deny that this in turn implies that meaning is normative. Jeffrey Kaplan has recently argued that while semantic correctness may not imply full-blown normativity, semantic correctness is not descriptive either. I contend that Kaplan's argument has two (...) main problems. First, his focus on dispositionalism leaves it open for other descriptive facts to provide the basis of semantic correctness conditions. Second, he fails to show that the problems of dispositionalism are connected to semantic correctness in a way that demonstrates problems with descriptive theories of meaning. (shrink)

The fact that the standard probabilistic calculus does not define probabilities for sentences with embedded conditionals is a fundamental problem for the probabilistic theory of conditionals. Several authors have explored ways to assign probabilities to such sentences, but those proposals have come under criticism for making counterintuitive predictions. This paper examines the source of the problematic predictions and proposes an amendment which corrects them in a principled way. The account brings intuitions about counterfactual conditionals to bear on the interpretation of (...) indicatives and relies on the notion of causal (in)dependence. (shrink)

The reasoning abilities of large language models (LLMs) are the topic of a growing body of research in AI and cognitive science. In this paper, we probe the extent to which twenty-nine LLMs are able to distinguish logically correct inferences from logically fallacious ones. We focus on inference patterns involving conditionals (e.g., 'If Ann has a queen, then Bob has a jack') and epistemic modals (e.g., 'Ann might have an ace', 'Bob must have a king'). These inferences have been of (...) special interest to logicians, philosophers, and linguists, since they play a central role in the fundamental human ability to reason about distal possibilities. Assessing LLMs on these inferences is thus highly relevant to the question of how much the reasoning abilities of LLMs match those of humans. All the LLMs we tested make some basic mistakes with conditionals or modals, though zero-shot chain-of-thought prompting helps them make fewer mistakes. Even the best performing LLMs make basic errors in modal reasoning, display logically inconsistent judgments across inference patterns involving epistemic modals and conditionals, and give answers about complex conditional inferences that do not match reported human judgments. These results highlight gaps in basic logical reasoning in today's LLMs. (shrink)

Metaethical absolutism is the view that moral concepts have non-relative satisfaction conditions that are constant across judges and their particular beliefs, attitudes, and cultural embedding. If it is correct, there is an important sense in which parties of moral disputes are concerned to get the same things right, such that their disputes can be settled by the facts. If it is not correct, as various forms of relativism and non-cognitivism imply, such coordination of concerns will be limited. The most (...) influential support for absolutism comes from an argument with two related premises. According to the first premise, moral thinking and moral discourse display a number of features that are characteristically found in paradigmatically absolutist domains, and only partly in uncontroversially non-absolutist domains. According to the second, the best way of making sense of these features is to assume that absolutism is correct. This paper defends the prospect of a non-ad hoc, non-absolutist, explanation of these "absolutist" features, thus calling into question the second premise. But instead of attempting to directly explain why the moral domain displays these features, it attends to how they are partially displayed by paradigmatically non-absolutists judgments about taste and likelihood. Based on this, it proposes independently motivated general accounts of attributions of agreement, disagreement, correctness and incorrectness that can explain both why absolutist domains display all "absolutist" features and why these non-absolutist domains display some. Based on these accounts, it provides preliminary reasons to think that these features of moral discourse can be given a non-absolutist explanation. (shrink)

Boethius' treatise De Hypotheticis Syllogismis provided twelfth-century philosophers with an introduction to the logic of conditional and disjunctive sentences but this work is the only part of the logica vetus which is no longer studied in the twelfth century. In this paper I investigate why interest in Boethius acount of hypothetical syllogisms fell off so quickly. I argue that Boethius' account of compound sentences is not an account of propositions and once a proper notion of propositionality is available the argument (...) forms accepted by Boethius are seen to be incoherent. It was Peter Abaelard who first understood the nature of propositionality and propositional connectives and used this to criticise Boethius' claims in De Hypothetics Syllogismis. In place Boethius' confusion Abaelard offered a simple and correct account of the hypothetical syllogism. (shrink)

According to what is now commonly referred to as “the Equation” in the literature on indicative conditionals, the probability of any indicative conditional equals the probability of its consequent of the conditional given the antecedent of the conditional. Philosophers widely agree in their assessment that the triviality arguments of Lewis and others have conclusively shown the Equation to be tenable only at the expense of the view that indicative conditionals express propositions. This study challenges the correctness of that assessment (...) by presenting data that cast doubt on an assumption underlying all triviality arguments. (shrink)

I set out and defend a view on indicative conditionals that I call “indexical relativism ”. The core of the view is that which proposition is expressed by an utterance of a conditional is a function of the speaker’s context and the assessor’s context. This implies a kind of relativism, namely that a single utterance may be correctly assessed as true by one assessor and false by another.

Conditional logics were originally developed for the purpose of modeling intuitively correct modes of reasoning involving conditional—especially counterfactual—expressions in natural language. While the debate over the logic of conditionals is as old as propositional logic, it was the development of worlds semantics for modal logic in the past century that catalyzed the rapid maturation of the field. Moreover, like modal logic, conditional logic has subsequently found a wide array of uses, from the traditional (e.g. counterfactuals) to the exotic (e.g. conditional (...) obligation). Despite the close connections between conditional and modal logic, both the technical development and philosophical exploitation of the latter has outstripped that of the former, with the result that noticeable lacunae exist in the literature on conditional logic. My dissertation addresses a number of these underdeveloped frontiers, producing new technical insights and philosophical applications. -/- I contribute to the solution of a problem posed by Priest of finding sound and complete labeled tableaux for systems of conditional logic from Lewis' V-family. To develop these tableaux, I draw on previous work on labeled tableaux for modal and conditional logic; errors and shortcomings in recent work on this problem are identified and corrected. While modal logic has by now been thoroughly studied in non-classical contexts, e.g. intuitionistic and relevant logic, the literature on conditional logic is still overwhelmingly classical. Another contribution of my dissertation is a thorough analysis of intuitionistic conditional logic, in which I utilize both algebraic and worlds semantics, and investigate how several novel embedding results might shed light on the philosophical interpretation of both intuitionistic logic and conditional logic extensions thereof. -/- My dissertation examines deontic and connexive conditional logic as well as the underappreciated history of connexive notions in the analysis of conditional obligation. The possibility of interpreting deontic modal logics in such systems (via embedding results) serves as an important theoretical guide. A philosophically motivated proscription on impossible obligations is shown to correspond to, and justify, certain (weak) connexive theses. Finally, I contribute to the intensifying debate over counterpossibles, counterfactuals with impossible antecedents, and take—in contrast to Lewis and Williamson—a non-vacuous line. Thus, in my view, a counterpossible like "If there had been a counterexample to the law of the excluded middle, Brouwer would not have been vindicated" is false, not (vacuously) true, although it has an impossible antecedent. I exploit impossible (non-normal) worlds—originally developed to model non-normal modal logics—to provide non-vacuous semantics for counterpossibles. I buttress the case for non-vacuous semantics by making recourse to both novel technical results and theoretical considerations. (shrink)

The Borel–Kolmogorov Paradox is typically taken to highlight a tension between our intuition that certain conditional probabilities with respect to probability zero conditioning events are well defined and the mathematical definition of conditional probability by Bayes’ formula, which loses its meaning when the conditioning event has probability zero. We argue in this paper that the theory of conditional expectations is the proper mathematical device to conditionalize and that this theory allows conditionalization with respect to probability zero events. The conditional probabilities (...) on probability zero events in the Borel–Kolmogorov Paradox also can be calculated using conditional expectations. The alleged clash arising from the fact that one obtains different values for the conditional probabilities on probability zero events depending on what conditional expectation one uses to calculate them is resolved by showing that the different conditional probabilities obtained using different conditional expectations cannot be interpreted as calculating in different parametrizations of the conditional probabilities of the same event with respect to the same conditioning conditions. We conclude that there is no clash between the correct intuition about what the conditional probabilities with respect to probability zero events are and the technically proper concept of conditionalization via conditional expectations—the Borel–Kolmogorov Paradox is just a pseudo-paradox.

A serious error in the proof of a recent characterization of the existence of full conditional probabilities invariant under symmetries is corrected.

The idea that dispositions are an intrinsic matter has been popular among contemporary philosophers of dispositions. In this paper I will first state this idea as exactly as possible. I will then examine whether it poses any threat to the two current versions of the conditional analysis of dispositions, namely, the simple and reformed conditional analysis of dispositions. The upshot is that the intrinsic nature of dispositions, when properly understood, doesn't spell trouble for either of the two versions of the (...) conditional analysis of dispositions. Along the way, I will propose an extensionally correct and practically useful criterion for identifying nomically intrinsic dispositions and criticize one objection raised by Lewis against the simple conditional analysis of dispositions.

This chapter was written in 2013 and was posted in the Semantics Archive in January 2014. The preprint of the published version has been in the Semantics Archive since 2016. The Semantics Archive is an electronic preprint archive hosted by the Linguistics Society of America. -/- The chapter looks at indicative conditionals embedded under quantifiers, with a special emphasis on ‘one-case’, episodic, conditionals as in "No query was answered if it came from a doubtful address." It agrees with earlier assessments (...) that a complete conditional (with antecedent and consequent) is embedded under a quantifier in those constructions, but then proceeds to create a dilemma by showing that we can’t always find the right interpretation for that conditional. Contrary to earlier assessments, Stalnaker’s conditional won’t always do. The paper concludes that the embedded conditional in the sentence above is a material implication, but the "if"-clause also plays a pragmatic role in restricting the domain of the embedding quantifier. That an appeal to pragmatics should be necessary at all goes with Edgington’s verdict that “we do not have a satisfactory general account of sentences with conditional constituents.” -/- One of the conclusions drawn at the end of the chapter is that the English modal "will" should be given a Stalnaker selection function analysis. The idea is implemented by attaching to "will" an accessibility function variable that receives its value from the context of use and can be dynamically updated by preceding "if"-clauses, as proposed in von Fintel (1994). The argument for a Stalnaker selection function analysis of "will" provided by the paper is that, together with the restrictor analysis of "if"-clauses, it yields the correct truth-conditions for "will"-conditionals (as opposed to episodic, 'one case', conditionals) embedded under quantifiers. The proposal that the English modal "will" should be given a Stalnaker selection function analysis has since been taken up and elaborated considerably in Cariani & Santorio's (2018) paper on "will" in Mind, and is a central idea in Cariani's (2021) book The Modal Future.

One popular approach to the metaphysics of dispositional properties takes them to involve ascribing a conditional property, a property corresponding to a conditional statement. This chapter looks at some recent work on the semantics and logic of conditionals, followed by a consideration of Hypotheticalism, Nomism, Neo‐Humeism, and Powerism. It examines directly the question whether Hypotheticalism or Anti‐Hypotheticalism (categoricalism) is correct, and shows how to evaluate counterfactual conditionals. The evaluation of conditionals seems to turn on two sorts of facts about the (...) actual world: the laws of nature, and the true propositions that are co‐tenable with the conditional's antecedent. Strong Hypotheticalists hold that the truths of counterfactual conditionals are fundamental, and that truths about the laws of nature and of powers and dispositions are reducible to them. (shrink)

This paper provides evidence for an ambiguity of bare VPs in the English conditional conjunction construction. This ambiguity, undetected by previous researchers, provides a key to the development of a compositional semantic analysis of conditional conjunction with imperative first conjuncts. The analysis combines existing semantic theories of imperatives, the future tense, modal subordination, and speech act conjunction to yield the correct semantics without further stipulation.

Wijdicks and colleagues1 recently presented the Full Outline of UnResponsiveness (FOUR) scale as an alternative to the Glasgow Coma Scale (GCS)2 in the evaluation of consciousness in severely brain-damaged patients. They studied 120 patients in an intensive care setting (mainly neuro-intensive care) and claimed that “the FOUR score detects a locked-in syndrome, as well as the presence of a vegetative state.”1 We fully agree that the FOUR is advantageous in identifying locked-in patients given that it specifically tests for eye movements (...) or blinking on command. This is welcomed given that misdiagnosis of the locked-in syndrome has been shown to occur in more than half of the cases (see Laureys and colleagues3 for review). As for the diagnosis of the vegetative state, the scale explicitly tests for visual pursuit, and hence can disentangle the vegetative state from the minimally conscious state (MCS). The diagnostic criteria for MCS have been proposed4 only recently, but Wijdicks and colleagues1 do not mention the existence of this clinical entity in their article. As for the vegetative state, MCS can be encountered in the acute or subacute setting as a transitional state on the way to further recovery, or it can be a more chronic or even permanent condition. The MCS refers to patients showing inconsistent, albeit clearly discernible, minimal behavioral evidence of consciousness (eg, localization of noxious stimuli, eye fixation or tracking, reproducible movement to command, or nonfunctional verbalization).4 The FOUR scale does not test for all of the behavioral criteria required to diagnose MCS.4 It is known from the literature (see Majerus and colleagues5 for review) that about a third of patients diagnosed with vegetative state are actually in MCS, and this misdiagnosis can lead to major clinical, therapeutic, and ethical consequences. We tested the ability of the newly proposed FOUR scale to correctly diagnose the vegetative state in an acute (intensive care and neurology ward) and chronic (neurorehabilitation) setting.. (shrink)

The use of new paradigms of false belief tasks (FBT) allowed to reduce the age of children who pass the test from the previous 4 years in the standard version to only 15 months or even a striking 6 months in the nonverbal modification. These results are often taken as evidence that infants already possess an—at least implicit—theory of mind (ToM). We criticize this inferential leap on the grounds that inferring a ToM from the predictive success on a false belief (...) task requires to assume as premise that a belief reasoning is a necessary condition for correct action prediction. It is argued that the FBT does not satisfactorily constrain the predictive means, leaving room for the use of belief-independent inferences (that can rely on the attribution of non-representational mental states or the consideration of behavioral patterns that dispense any reference to other minds). These heuristics, when applied to the FBT, can achieve the same predictive success of a belief-based inference because information provided by the test stimulus allows the recognition of particular situations that can be subsumed by their ‘laws’. Instead of solving this issue by designing a single experimentum crucis that would render unfeasible the use of non-representational inferences, we suggest the application of a set of tests in which, although individually they can support inferences dissociated from a ToM, only an inference that makes use of false beliefs is able to correctly predict all the outcomes.

The enduring replication crisis in many scientific disciplines casts doubt on the ability of science to estimate effect sizes accurately, and in a wider sense, to self-correct its findings and to produce reliable knowledge. We investigate the merits of a particular countermeasure—replacing null hypothesis significance testing with Bayesian inference—in the context of the meta-analytic aggregation of effect sizes. In particular, we elaborate on the advantages of this Bayesian reform proposal under conditions of publication bias and other methodological imperfections that (...) are typical of experimental research in the behavioral sciences. Moving to Bayesian statistics would not solve the replication crisis single-handedly. However, the move would eliminate important sources of effect size overestimation for the conditions we study.

At the center of the literature on conditionals lies the division between indicative and subjunctive conditionals, and Ernest Adams’ famous minimal pair: If Oswald didn’t shoot Kennedy, someone else did. If Oswald hadn’t shot Kennedy, someone else would have. While a lot of attention is paid to figuring out what these different kinds of conditionals mean, significantly less attention has been paid to the question of why their grammatical differences give rise to their semantic differences. In this paper, I articulate (...) and defend an answer to this question that illuminates and unifies the meanings of both kinds of conditionals. The basic idea is that epistemic and metaphysical possibilities differ with respect to their interaction with time, such that there can be present epistemic possibilities with different pasts, while present metaphysical possibilities share the same past. The interpretation of conditionals is subject to a pragmatic constraint that rules out interpretations in which their consequents are directly settled by information used to build their domains. The past + future morphology on subjunctives, but not indicatives, is what allows them to receive a metaphysical interpretation in light of this pragmatic constraint. The resulting theory predicts several surprising features of indicatives and subjunctives, which I argue are correct. (shrink)

"If you turn left at the next corner, you will see a blue house at the end of the street." That sentence -- a conditional -- might be true even though it is possible that you will not see a blue house at the end of the street when you turn left at the next corner. A moving van may block your view; the house may have been painted pink; a crow might swoop down and peck out your eyes. Still, (...) in some contexts, we might ignore these possibilities and correctly assert the conditional. In this book, Christopher Gauker argues that such context-relativity is the key to understanding the semantics of conditionals. Contexts are defined as objective features of the situation in which a conversation takes place, and the semantic properties of sentences -- conditionals included -- are defined in terms of assertibility in a context. One of the primary goals of a theory of conditionals has to be to distinguish correctly between valid and invalid arguments containing conditionals. According to Gauker, an argument is valid if the conclusion is assertible in every context in which the premises are assertible. This runs counter to what Gauker sees as a systematic misreading of the data by other authors, who judge arguments to be invalid if they can think of a context in which the premises are judged true and some other context in which the conclusion is judged false. Different schools of thought on conditionals reflect fundamentally different approaches to semantics. Gauker offers his theory as a motive and test case for a distinctive kind of semantics that dispenses with reference relations and possible worlds. (shrink)

The article deals with one particular problem created by the counterfactual analysis of causality à la Lewis, namely the context-sensitivity problem or, as I prefer to call it, the background condition problem. It appears that Lewis’ counterfactual definition of causality cannot distinguish between proper causes and mere causal conditions – i.e. factors necessary for the effect to occur, but commonly not seen as causally efficacious. The proposal is put forward to amend the Lewis definition with a condition, based on (...) the notion of cotenability, which would eliminate the problem. It is shown that the corrected definition of causality leads to the transitivity of the causal relation. Possible objections to the proposed solution, involving the assumption of indeterminism and the preemption cases, are given a thorough consideration. (shrink)

Conditional logics have traditionally been intended to formalize various intuitively correct modes of reasoning involving conditional expressions in natural language. Although conditional logics have by now been thoroughly studied in a classical context, they have yet to be systematically examined in an intuitionistic context, despite compelling philosophical and technical reasons to do so. This paper addresses this gap by thoroughly examining the basic intuitionistic conditional logic ICK, the intuitionistic counterpart of Chellas’ important classical system CK. I give ICK both worlds (...) semantics and algebraic semantics, and prove that these are equivalent. I give a Gödel-type embedding of ICK into CK and a Glivenko-type embedding of CK into ICK. I axiomatize ICK and prove soundness, completeness, and decidability results. Finally, I discuss extending ICK. (shrink)

In The Norm of Belief, John Gibbons claims that there is a “natural reaction” to the general idea that one can be normatively required to Ø when that requirement is in some sense outside of one’s first person perspective or inaccessible to one. The reaction amounts to the claim that this is not possible. Whether this is a natural or intuitive idea or not, it is difficult to articulate exactly why we might think it is correct. To do so, we (...) need a view about the relationship between agents’ capacities to accord with normative requirements and the conditions under which those normative requirements obtain. I offer an account of the epistemic dimension of this relationship. The goal is to provide enough of a story about the natural reaction to make accounting for it look like an important desideratum for any theory of the nature of normative requirements—whether these are moral or epistemic. To focus the discussion, I use Timothy Williamson’s knowledge-first view of evidence as an example of a view in epistemology that generates the natural reaction. One upshot of the discussion, then, is a detailed account of what is troubling about Williamson’s influential but controversial view of evidence. (shrink)

In this paper I will argue that Professor Goodman was correct in thinking that there is a problem concerning counterfactual conditionals, but that it is somewhat different from the problem he thought it to be, and is one that is even more basic. I will also try to show that this problem is distinct from Hume's "problem" of induction, and that additional assumptions have to be made for counterfactual induction beyond those required for other kinds of induction.

Understanding the flow of knowledge in multi-agent protocols is essential when proving the correctness or security of such protocols. Current logical approaches, often based on model checking, are well suited for modeling knowledge in systems where agents do not act strategically. Things become more complicated in strategic settings. In this paper we show that such situations can be understood as a special type of game – a knowledge condition game – in which a coalition “wins” if it is able (...) to bring about some epistemic condition. This paper summarizes some results relating to these games. Two proofs are presented for the computational complexity of deciding whether a coalition can win a knowledge condition game with and without opponents (Σ2P-complete and NP-complete respectively). We also consider a variant of knowledge condition games in which agents do not know which strategies are played, and prove that under this assumption, the presence of opponents does not affect the complexity. The decision problem without opponents is still NP-complete, but requires a different proof. (shrink)
