My dissertation asks how we affect conversational context and how it affects us when we participate in any conversation—including philosophical conversations. Chapter 1 argues that speakers make pragmatic presuppositions when they use proper names. I appeal to these presuppositions in giving a treatment of Frege’s puzzle that is consistent with the claim that coreferential proper names have the same semantic value. I outline an explanation of the way presupposition carrying expressions in general behave in belief ascriptions, and suggest that substitutivity (...) failure is a special case of this behavior. Chapter 2 develops a compositional probabilistic semantics for the language of subjective uncertainty, including epistemic adjectives scoped under quantifiers. I argue that we should distinguish sharply between the effects that epistemically hedged statements have on conversational context, and the effects that they have on belief states. I also suggest that epistemically hedged statements are a kind of doxastic advice, and explain how this hypothesis illuminates some otherwise puzzling phenomena. Chapter 3 argues that ordinary causal talk is deeply sensitive to conversational context. The principle that I formulate to characterize that context sensitivity explains at least some of the oddness of ‘systematic causal overdetermination,’ and explains why some putative overgenerated causes are never felicitously counted, in conversation, as causes. But the principle also makes metaphysical theorizing about causation rather indirectly constrained by ordinary language judgments. (shrink)

Aristotle's theory of moral character focuses on developing virtues, the deep internal dispositional traits from which external actions naturally flow. Aristotle describes moral virtue as a human excellence that can be developed through practice. The morally worst person is the vicious person who does the wrong thing, desires the wrong thing, and doesn't even know the right thing to do—perhaps even mistaking the wrong thing to do for the right thing. This was the sort of person Eleanor was when she (...) entered The Good Place. One objection to the possibility of moral development is called situationism: the claim that people don't really live according to moral character but are overwhelmingly shaped by the situations around them. As Eleanor learns in The Good Place, the road to being a better person starts with caring about those close to us. (shrink)

Though hippocampal volume reduction is a pathological hallmark of schizophrenia, the molecular pathway responsible for this degeneration remains unknown. Recent reports have suggested the potential role of impaired blood-brain barrier function in schizophrenia pathogenesis. However, direct evidence demonstrating an impaired BBB function is missing. In this preliminary study, we used immunohistochemistry and serum immunoglobulin G antibodies to investigate the state of BBB function in formalin-fixed postmortem samples from the hippocampus and surrounding temporal cortex of patients with schizophrenia and controls without (...) schizophrenia matched for age, sex, and race. Since a functional BBB prevents the extravasation of IgGs, detection of IgGs in the parenchyma is used as direct evidence of BBB breakdown. We also developed a semi-quantitative approach to quantify the extent of IgG leak and therein BBB breach. Analysis of our immunohistochemistry data demonstrated a significantly higher incidence of IgG leak in patients with schizophrenia compared to controls. Further, BBB permeability was significantly higher in advanced-age patients with schizophrenia than both advanced-age controls and middle-aged patients with schizophrenia. Male patients with schizophrenia also demonstrated a significant increase in IgG permeability compared to control males. Interestingly, the extravasated IgGs also demonstrated selective immunoreactivity for neurons. Based on these observations, we suggest that BBB dysfunction and IgG autoantibodies could be two key missing pathoetiological links underwriting schizophrenia hippocampal damage. (shrink)

This paper develops a compositional, type-driven constraint semantic theory for a fragment of the language of subjective uncertainty. In the particular application explored here, the interpretation function of constraint semantics yields not propositions but constraints on credal states as the semantic values of declarative sentences. Constraints are richer than propositions in that constraints can straightforwardly represent assessments of the probability that the world is one way rather than another. The richness of constraints helps us model communicative acts in essentially the (...) same way that we model agents’ credences. Moreover, supplementing familiar truth-conditional theories of epistemic modals with constraint semantics helps capture contrasts between strong necessity and possibility modals, on the one hand, and weak necessity modals, on the other.

One potentially ethically relevant feature of an utterance is that utterance's influence on the likelihoods that our future discourses wind up with one Stalnakerian ‘common ground’ or body of shared information rather than another. Such likelihoods matter ethically, so the ways our utterances influence them can matter ethically, despite the fact that such influences are often unintended, and often hard to see. By offering a relatively neutral descriptive framework that can enhance our collective sensitivity to and discussion of ethically, socially, (...) and politically important features of language use, this paper contributes to the ethics of language use. It discusses ways in which utterances can influence the likelihoods of future common grounds by deploying one system of categorization rather than another, and argues that language’s effects on the evolution of discourse can affect the paths to and probabilities of different sorts of consensus.

A successful theory of the language of subjective uncertainty would meet several important constraints. First, it would explain how use of the language of subjective uncertainty affects addressees’ states of subjective uncertainty. Second, it would explain how such use affects what possibilities are treated as live for purposes of conversation. Third, it would accommodate 'quantifying in' to the scope of epistemic modals. Fourth, it would explain the norms governing the language of subjective uncertainty, and the differences between them and the (...) norms governing the language of subjective certainty. Neither truth conditional nor traditional force modfier theories of the language of subjective uncertainty look adequate to the task of satisfying all four of these constraints. (shrink)

© Swanson 2017How Propaganda Works is a brilliant, rich, and wide-ranging exploration of the interactions between ideology, inequality, democracy and propaganda. Read as a piece of analytic political philosophy, it is radical, arguing for bold theses about democracy: legitimate democratic deliberation, Stanley contends, requires not only political equality but also substantive material equality. Read as a piece of analytic epistemology and philosophy of language, it is more modest, but nevertheless very compelling, extending well-established work in fascinating but methodologically conservative (...) ways. In particular, on Stanley’s view ‘the truth-conditional, cognitivist picture … gives us an elegant account of what happens when communication fails, due to propagandistic manipulation’. Stanley is thus not trying to think outside the box so much as trying to move or expand the box, using familiar, proven tools to make the job easier. The book generously rewards careful study and thought, and any short summary... (shrink)

This article discusses some of the ways in which natural language can express modal information – information which is, to a first approximation, about what could be or must be the case, as opposed to being about what actually is the case. It motivates, explains, and raises problems for Angelika Kratzer's influential theory of modal auxiliaries, and introduces a new approach to one important debate about the relationships between modality, evidentiality, context change, and imperative force.

In his original semantics for counterfactuals, David Lewis presupposed that the ordering of worlds relevant to the evaluation of a counterfactual admitted no incomparability between worlds. He later came to abandon this assumption. But the approach to incomparability he endorsed makes counterintuitive predictions about a class of examples circumscribed in this paper. The same underlying problem is present in the theories of modals and conditionals developed by Bas van Fraassen, Frank Veltman, and Angelika Kratzer. I show how to reformulate all (...) these theories in terms of lower bounds on partial preorders, conceived of as maximal antichains, and I show that treating lower bounds as cutsets does strictly better at capturing our intuitions about the semantics of modals, counterfactuals, and deontic conditionals.

This paper presents and discusses a range of counterexamples to the common view that quantifiers cannot take scope over epistemic modals. Some of the counterexamples raise problems for ‘force modifier’ theories of epistemic modals. Some of the counterexamples raise problems for Robert Stalnaker’s theory of counterfactuals, according to which a special kind of epistemic modal must be able to scope over a whole counterfactual. Finally, some of the counterexamples suggest that David Lewis must countenance ‘would’ counterfactuals in which a covert (...) ‘would’ scopes over the whole consequent of the counterfactual, including an overt ‘might.’.

In some contexts, not saying S generates a conversational implicature: that the speaker didn’t have sufficient reason, all things considered, to say S. I call this an omissive implicature. Standard ways of thinking about conversational implicature make the importance and even the existence of omissive implicatures somewhat surprising. But I argue that there is no principled reason to deny that there are such implicatures, and that they help explain a range of important phenomena. This paper focuses on the roles omissive (...) implicatures play in Quantity implicatures—in particular, in solving the symmetry problem for scalar implicatures—and on the political and social importance of omissions where apologies, objections, or other communicative acts are expected or warranted.

Conventional wisdom has it that many intriguing features of indicative conditionals aren’t shared by subjunctive conditionals. Subjunctive morphology is common in discussions of wishes and wants, however, and conditionals are commonly used in such discussions as well. As a result such discussions are a good place to look for subjunctive conditionals that exhibit features usually associated with indicatives alone. Here I offer subjunctive versions of J. L. Austin’s ‘biscuit’ conditionals—e.g., “There are biscuits on the sideboard if you want them”—and subjunctive (...) versions of Allan Gibbard’s ‘stand-off’ or ‘Sly Pete’ conditionals, in which speakers with no relevant false beliefs can in the same context felicitously assert conditionals with the same antecedents and contradictory consequents. My cases undercut views according to which the indicative/subjunctive divide marks a great difference in the meaning of conditionals. They also make trouble for treatments of indicative conditionals that cannot readily be generalized to subjunctives. (shrink)

Philosophy and Phenomenological Research, Volume 104, Issue 1, Page 171-185, January 2022.

Many philosophical theories make comparisons between objects, events, states of affairs, worlds, or systems, and many such theories deliver plausible verdicts only if some of the elements they compare are ranked as ‘best.’ When the relevant ordering does not have such ‘best’ or ‘tied for best’ elements the theory wrongly falls silent or gives badly counterintuitive results. This paper develops ordering supervaluationism---a very general technique that allows any such theory to handle these problematic cases. Just as ordinary supervaluation helps us (...) save and generalize ‘uniqueness assuming’ theories, ordering supervaluationism helps us save and generalize ‘limit assuming’ theories. With so many otherwise attractive limit assuming theories, this is a sensible, methodologically conservative approach. (shrink)

In his recent paper on the symmetry problem Roni Katzir argues that the only relevant factor for the calculation of any Quantity implicature is syntactic structure. I first refute Katzir’s thesis with three examples that show that structural complexity is irrelevant to the calculation of some Quantity implicatures. I then argue that it is inadvisable to assume—as Katzir and others do—that exactly one factor is relevant to the calculation of any Quantity implicature.

Reflections on Meaning refines Paul Horwich’s use theory of meaning. Horwich holds that the meaning of a word is constituted by the nonsemantic property that best explains a certain law. For a given word, the law to be explained governs that word’s use by specifying the “acceptance conditions” of a privileged class of sentences containing the word (26). Horwich devotes considerable energy to details in Reflections on Meaning and focuses on especially pressing problems for his use theory of meaning. As (...) a result the book’s topics run the gamut, and the connections between its chapters are not always strong. Rather than try to provide a synoptic overview, I’ll discuss three areas where it seems further clarification and detail could be fruitful: the distinction between semantic and nonsemantic properties, context sensitivity, and compositionality. Horwich thinks ours is a “fundamentally non-semantic world” (27), making it crucial that meaning be explained in nonsemantic terms. In particular, he insists that we “exclude from the analyzing-properties [of word meaning] anything that would itself require analysis in terms of meaning”: we can’t appeal to reference, belief, or intention, for example (37). But Horwich does not object to “accounts of meaning in psychological terms,” and his own theory relies heavily on a psychological, nonsemantic relation that Horwich calls “acceptance” (37). It’s difficult to see a substantive difference between this technical notion and belief. Acceptance, for Horwich, is “the psychological (but nonsemantic) relation to a sentence that is manifested in our relying on it as a premise in theoretical and practical inference” (40–41). Belief, on the other hand, is a relation with these properties except that it is semantic. Horwich’s other characterizations of acceptance don’t sharpen the distinction very much: “S accepts a sentence just in case that sentence, or its mental correlate, is in S’s belief box” (41); “believing a given proposition is nothing more than accepting some sentence that expresses it” (61)..

Until recently it was standard to think that all demonstratives are directly referential. This assumption has played important roles in work on perception, reference, mental content, and the nature of propositions. But Jeff King claims that demonstratives with a nominal complement (like ‘that dog’) are quantifiers, largely because there are cases in which the semantic value of such a “complex demonstrative” is not simply an object (2001). Although I agree with King that such cases preclude a directly referential, Kaplanian semantics (...) for complex demonstratives, I will argue that without contentious further assumptions they do not vindicate King’s claim that they are quantifiers. This is because familiar pronouns act like King’s examples of complex demonstratives. Indeed, pronouns and complex demonstratives share behavior that even King overlooks. None of this pronoun behavior shows that pronouns are quantifiers, and similarly none of the analogous demonstrative behavior shows that complex demonstratives are quantifiers. (shrink)

I argue that there are some causal relata for which it is indeterminate whether one caused the other. Positing indeterminacy in causation helps us defend contested principles in the logic of causation and makes possible new ways of thinking about the theoretical impact of symmetric causal overdetermination. I close by discussing amendments of current theories of causation that would help explain causal indeterminacy.

We can think of ordinary truth-conditional semantics as giving us constraints on cognitive states. But constraints on cognitive states can be more complicated than simply believing a proposition. And we communicate more complicated constraints on cognitive states. We also communicate constraints that seem to bear on affective and conative states.

We present a one per cent measurement of the cosmic distance scale from the detections of the baryon acoustic oscillations in the clustering of galaxies from the Baryon Oscillation Spectroscopic Survey, which is part of the Sloan Digital Sky Survey III. Our results come from the Data Release 11 sample, containing nearly one million galaxies and covering approximately 8500 square degrees and the redshift range 0.2 < z < 0.7. We also compare these results with those from the publicly released (...) DR9 and DR10 samples. Assuming a concordance Λ cold dark matter cosmological model, the DR11 sample covers a volume of 13 Gpc3 and is the largest region of the Universe ever surveyed at this density. We measure the correlation function and power spectrum, including density-field reconstruction of the BAO feature. The acoustic features are detected at a significance of over 7σ in both the correlation function and power spectrum. Fitting for the position of the acoustic features measures the distance relative to the sound horizon at the drag epoch, rd, which has a value of rd,fid = 149.28 Mpc in our fiducial cosmology. We find DV = at z = 0.32 and DV = at z = 0.57. At 1.0 per cent, this latter measure is the most precise distance constraint ever obtained from a galaxy survey. Separating the clustering along and transverse to the line of sight yields measurements at z = 0.57 of DA = and H =. Our measurements of the distance scale are in good agreement with previous BAO measurements and with the predictions from cosmic microwave background data for a spatially flat CDM model with a cosmological constant. © 2014 The Author Published by Oxford University Press on behalf of the Royal Astronomical Society.

Here I consider the two most venerated arguments about the existence of God: the Ontological Argument and the Argument from Evil. The Ontological Argument purports to show that God’s nature guarantees that God exists. The Argument from Evil purports to show that God’s nature, combined with some plausible facts about the way the world is, guarantees (or is very compelling grounds for thinking) that God does not exist. Obviously, both arguments cannot be sound. But I argue here that they are (...) both unsound for the very same reason. (shrink)

This Element introduces the philosophical literature on models, with an emphasis on normative considerations relevant to models for decision-making. Chapter 1 gives an overview of core questions in the philosophy of modeling. Chapter 2 examines the concept of model adequacy for purpose, using three examples of models from the atmospheric sciences to describe how this sort of adequacy is determined in practice. Chapter 3 explores the significance of using models that are not adequate for purpose, including the purpose of informing (...) public decisions. Chapter 4 provides a basic framework for values in modelling, using a case study to highlight the ethical challenges in building models for decision making. It concludes by establishing the need for strategies to manage value judgments in modelling, including the potential for public participation in the process. (shrink)

We review and present a new meta‐analysis of research suggesting that ethicists in the United States appear to behave no morally better overall than do non‐ethicist professors. Measures include: returning library books, peer evaluation of overall moral behavior, voting participation, courteous and discourteous behavior at conferences, replying to student emails, paying conference registration fees and disciplinary society dues, staying in touch with one's mother, charitable giving, organ and blood donation, vegetarianism, and honesty in responding to survey questions. One multi‐measure study (...) found ethicists tending to embrace more stringent moral views, especially about meat eating and charitable donation. The same multi‐measure study found ethicists and other professors to show similarly small‐to‐medium correlations between their expressed normative attitudes and their self‐reported or directly measured behavior.

There are many alleged problems with trusting another person’s moral testimony, perhaps the most prominent of which is that it fails to deliver moral understanding. Without moral understanding, one cannot do the right thing for the right reason, and so acting on trusted moral testimony lacks moral worth. This chapter, however, argues that moral advice differs from moral testimony, differs from it in a way that enables a defender of moral advice to parry this worry about moral worth. The basic (...) idea is that an advisor and an advisee can together constitute a joint agent, and that this joint agent’s action can indeed have moral worth. So while the advisee himself might not do the right thing for the right reason (this because all alone he lacks the right reason), and while the advisor herself might not do the right thing for the right reason (this because all alone she does not do the right thing), they together do the right for the right reason.

In 1970 a coalition of student activists opposing the Vietnam War circulated documents revealing the involvement of several prominent social scientists in U.S. counterinsurgency activities in Thailand--activities that could cause harm to the people who were the subject of the scholars' research. The disclosure of these materials, which detailed meetings with the Agency for International Development and the Defense Department, prompted two members of the Ethics Committee of the American Anthropological Association to issue an unauthorized rebuke of the accused. Over (...) the next two years, the AAA agonized over the allegations and the appropriate response to them. Within an academic community already polarized by the war, political and professional acrimony reached unprecedented levels. Although the association ultimately passed a code of ethics, the key issues raised in the process were never fully resolved. Now back in print, Eric Wakin's Anthropology Goes to War is the first comprehensive study of what became known as the Thailand Controversy--and a timely reminder of a debate whose echoes may be heard in our own time.

This paper argues that under some conditions, when one person acts on the direction of another person, the two of them thereby act together, and that this explains why both the director and the directee can be responsible for what is done.

But it is also sometimes (...) so when the directive is a bit of advice. (shrink)

In his work on Wu wei, Edward Slingerland argues that the classical Chinese ideal is an inherently paradoxical concept that is first and foremost spiritual and political only secondarily. Through a close reading of the Dao de Jing, the first major classical text to substantially deploy and develop the concept, I argue that Wu wei isn’t inherently paradoxical and that this is seen precisely when it is viewed in terms of its political primacy. On my reading, the emergence of Wu (...) wei in the Daoist canon is an equilibrating moment of political mediation between the highly intentionalized sphere of human pursuits and the purposeless fluidity and boundless flux of the natural world. Wu wei here takes on a different aspect—mystery rather than paradox—when considered within a form of political collectivity in which the intentional and the innate, purposive and natural are constantly juxtaposed and contending with one another.

Are philosophical arguments as effective as narratives in influencing charitable giving and attitudes toward it? In four experiments, we exposed online research participants to either philosophical arguments in favor of charitable giving, a narrative about a child whose life was improved by charitable donations, both the narrative and the argument, or a control text (a passage from a middle school physics text or a description of charitable organizations). Participants then expressed their attitudes toward charitable giving and were either asked how (...) much they would hypothetically donate if given $10 (Experiment 1) or told they had a 10% chance of winning $10 and given the opportunity to donate from their potential winnings (Experiments 2–4). Across the four experiments, participants in all of the narrative conditions and in some of the argument conditions tended to express more positive attitudes toward charitable giving and donated about $1 more on average than did participants in the control conditions. These effects appear to have been mediated by the “narrative transportation” scale, which suggests that appeals to donate can be effective if they engage participants’ emotions, imagery, and interest.

Most philosophers writing about personal identity in recent years claim that what it takes for us to persist through time is a matter of psychology. In this groundbreaking new book, Eric Olson argues that such approaches face daunting problems, and he defends in their place a radically non-psychological account of personal identity. He defines human beings as biological organisms, and claims that no psychological relation is either sufficient or necessary for an organism to persist. Olson rejects several famous thought-experiments (...) dealing with personal identity. He argues, instead, that one could survive the destruction of all of one's psychological contents and capabilities as long as the human organism remains alive--as long as its vital functions, such as breathing, circulation, and metabolism, continue.
