Among semanticists and philosophers of language, there has been a recent outburst of interest in predicates such as delicious, called predicates of personal taste (PPTs, e.g. Lasersohn 2005). Somewhat surprisingly, the question of whether or how we can distinguish aesthetic predicates from PPTs has hardly been addressed at all in this recent work. It is precisely this question that we address. We investigate linguistic criteria that we argue can be used to delineate the class of specifically aesthetic adjectives. We show (...) that there are, in fact, good motivations for keeping PPTs and aesthetic predicates apart: the semantic structure of the former, but not the latter, entails an experiencer. There are many adjectives whose semantic structure arguably also entails an experiencer, yet which are readily used in expressing aesthetic judgments. Adjectives such as provocative or moving are a case in point, since as adjectives they arguably maintain the experiencer argument from the verb they are derived from. Nevertheless, when we describe, say, a sculpture as provocative, or a theater performance as moving, we clearly make aesthetic judgments. The difficult question, then, is to articulate the relationship between an aesthetic predicate (of which beautiful and ugly are paradigms) and other predicates that just happen to be used in making an aesthetic judgment. Tightly related to this point is the more general question of the relationship between an evaluative predicate and a predicate that occurs in an evaluative judgment. One of our aims is to make some progress in addressing these questions. (shrink)

Even-like particles have widely been analyzed as inducing scalar and additive presuppositions (cf. Horn 1969; Karttunen & Peters 1979; Rooth 1992; Gast & van der Auwera 2011). However, the additivity of even has been controversial since at least Horn 1992 and increasingly called into question (see Greenberg & Umbach 2021 for references); Greenberg specifically argues that scalar even-like particles can vary in additivity. This claim is surprising in light of the typological study in Gast & van der Auwera 2011, which (...) subsumes even and similar expressions under a larger class of additive particles. Against this background, we present an analysis of Italian addirittura, which with perfino has been described as scalar-additive (Visconti 2005) – but only optionally so – and is chosen preferentially over perfino precisely in those contexts that Greenberg takes to challenge the additivity of even. We argue, drawing on observations in Atayan 2017, that addirittura contrasts with perfino in deriving its scalar alternatives from rhetorical structure rather than focus structure. Once this is recognized we can view addirittura as additive, after all, in a rhetorical sense we describe below. (shrink)

Eugenics is an overused, and often mis-used phrase, when applied to the handicap ground for abortion, argues Ruth McNally. Instead, we should be aware of the power of eubionics – the quest for individual, bodily perfection.

The goal of this short paper is to show that esthetic adjectives—exemplified by “beautiful” and “elegant”—do not pattern stably on a range of linguistic diagnostics that have been used to taxonomize the gradability properties of adjectives. We argue that a plausible explanation for this puzzling data involves distinguishing two properties of gradable adjectives that have been frequently conflated: whether an adjective’s applicability is sensitive to a comparison class, and whether an adjective’s applicability is context-dependent.

Mark Eli Kalderon presents an original study of perception, taking as its starting point a puzzle in Empedocles' theory of vision: if perception is a mode of material assimilation, how can we perceive colors at a distance? Kalderon argues that the theory of perception offered by Aristotle in answer to the puzzle is both attractive and defensible.

Several authors have recently endorsed the thesis that there is what has been called pragmatic encroachment on knowledge—in other words, that two people who are in the same situation with respect to truth-related factors may differ in whether they know something, due to a difference in their practical circumstances. This paper aims not to defend this thesis, but to explore how it could be true. What I aim to do, is to show how practical factors could play a role in (...) defeating knowledge by defeating epistemic rationality—the very kind of rationality that is entailed by knowledge, and in which Pascalian considerations do not play any role—even though epistemic rationality consists in having adequate evidence.

This paper explores how philosophical accounts of the nature of persons and attributive responsibility can help us to make sense of the kinds of characteristic errors that people make in interpreting what is attributable to one another. I show how this gives us an important tool for understanding some important kinds of interpersonal conflict, with particular attention to understanding why Maya Angelou's advice that "when someone shows you who they are, believe them the first time" can seem easier to have (...) followed from the privileged perspective of retrospection than it really was in prospect.

This chapter explores a case study in contemporary fanaticism. We adopt Katsafanas’s conceptualization of fanaticism to make possible an in-depth discussion of and evaluation of a diffuse but important social movement — the anglophone manosphere. According to Katsafanas, fanatics are fruitfully understood as members of a group that adopts sacred values which they hold unconditionally to preserve their own psychic unity, and who feel that those values are threatened by those who do not accept them. The manosphere includes several social (...) movements, including incels, men’s rights activists, and men-going-their-own-way. We show that many members of these groups are well-characterized by Katsafanas’s theory of fanaticism, and that they have forged their fanatical group identity using tools that philosophers have tended to associate with more benign social movements and the task of “conceptual engineering.” Indeed, we think that manosphere groups have in many cases been more successful than more palatable liberationist movements, and that this case study in the dark side of conceptual engineering may be both sobering and informative.

Using path-breaking discoveries of cognitive science, Mark Johnson argues that humans are fundamentally imaginative moral animals, challenging the view that morality is simply a system of universal laws dictated by reason. According to the Western moral tradition, we make ethical decisions by applying universal laws to concrete situations. But Johnson shows how research in cognitive science undermines this view and reveals that imagination has an essential role in ethical deliberation. Expanding his innovative studies of human reason in Metaphors We (...) Live By and The Body in the Mind, Johnson provides the tools for more practical, realistic, and constructive moral reflection.

forthcoming in reisner and steglich-peterson, eds., Reasons for Belief If I believe, for no good reason, that P and I infer (correctly) from this that Q, I don’t think we want to say that I ‘have’ P as evidence for Q. Only things that I believe (or could believe) rationally, or perhaps, with justification, count as part of the evidence that I have. It seems to me that this is a good reason to include an epistemic acceptability constraint on evidence (...) possessed…1 It is a truism that adopting an unjustified belief does not put you in a better evidential position with respect to believing its consequences. This truism has led many philosophers to assume that there must, at a minimum, be a justification condition (and perhaps even a knowledge condition) on what it takes to count as having evidence. This is the best (or only) possible explanation of the truism, these philosophers have believed. This paper explores an alternative explanation for the truism. According to the alternative explanation that I will offer, unjustified beliefs do not put you in a better evidential position with respect to believing their consequences because any evidence you have in virtue of having an unjustified belief is guaranteed to be defeated. Since the lack of justification for a belief guarantees its defeat, I will suggest, we don't need to postulate a special justification condition (much less a knowledge condition) on what it takes to count as having evidence. Why is this important? It is important because the assumption that there must be a justification condition (or perhaps a knowledge condition) on what it takes to count as having evidence places a high bar on what it takes to have evidence - such a high bar that it is difficult to see how this bar could be met in the case of basic, perceptually justified beliefs. As a result, the high bar set by this condition plays a fundamental role, I will claim, in central features of a core dialectic from the epistemology of basic perceptual belief which plays a central role in the debates between internalism and externalism, foundationalism and coherentism, and rationalism and empiricism..

Throughout the biological and biomedical sciences there is a growing need for, prescriptive ‘minimum information’ (MI) checklists specifying the key information to include when reporting experimental results are beginning to find favor with experimentalists, analysts, publishers and funders alike. Such checklists aim to ensure that methods, data, analyses and results are described to a level sufficient to support the unambiguous interpretation, sophisticated search, reanalysis and experimental corroboration and reuse of data sets, facilitating the extraction of maximum value from data sets (...) them. However, such ‘minimum information’ MI checklists are usually developed independently by groups working within representatives of particular biologically- or technologically-delineated domains. Consequently, an overview of the full range of checklists can be difficult to establish without intensive searching, and even tracking thetheir individual evolution of single checklists may be a non-trivial exercise. Checklists are also inevitably partially redundant when measured one against another, and where they overlap is far from straightforward. Furthermore, conflicts in scope and arbitrary decisions on wording and sub-structuring make integration difficult. This presents inhibit their use in combination. Overall, these issues present significant difficulties for the users of checklists, especially those in areas such as systems biology, who routinely combine information from multiple biological domains and technology platforms. To address all of the above, we present MIBBI (Minimum Information for Biological and Biomedical Investigations); a web-based communal resource for such checklists, designed to act as a ‘one-stop shop’ for those exploring the range of extant checklist projects, and to foster collaborative, integrative development and ultimately promote gradual integration of checklists.

Research notes of Mark Pettinelli about cognitive science, cognitive psychology.

Propositions are often aligned with truth-conditions. The view is mistaken, since propositions discriminate where truth conditions do not. Propositions are hyperintensional: they are sensitive to necessarily equivalent differences. I investigate an alternative view on which propositions are truthmaker conditions, understood as sets of possible truthmakers. This requires making metaphysical sense of merely possible states of affairs. The theory that emerges illuminates the semantic phenomena of samesaying, subject matter, and aboutness.

The Razor says: do not multiply entities without necessity! The Laser says: do not multiply fundamental entities without necessity! Behind the Laser lies a deep insight. This is a distinction between the costs and the commitments of a theory. According to the Razor, every commitment is a cost. Not so according to the Laser. According to the Laser, derivative entities are an ontological free lunch: that is, they are a commitment without a cost. Jonathan Schaffer (2015) has argued that the (...) Laser should replace the Razor. In Sections 2-4 we shall discuss and argue against Schaffer’s arguments for replacing the Razor with the Laser. Schaffer considers several objections to his views, and in Sections 5-7 we shall argue that Schaffer does not deal successfully with two of them. In Section 8 we shall present a probabilistic argument for the Laser. However, the argument has a limitation and does not support the replacement of the Razor with the Laser. Indeed, it supports only the claim that, given certain assumptions, the multiplication of explanatorily relevant derivative entities does not matter; but, as we argue in the same section, there is an argument that multiplying explanatorily superfluous derivative entities does makes a theory less rationally acceptable. Our conclusion is that the Laser cannot replace the Razor and that derivative entities are not an ontological free lunch. (shrink)

Beliefs are concrete particulars containing ideas of properties and notions of things, which also are concrete. The claim made in a belief report is that the agent has a belief (i) whose content is a specific singular proposition, and (ii) which involves certain of the agent's notions and ideas in a certain way. No words in the report stand for the notions and ideas, so they are unarticulated constituents of the report's content (like the relevant place in "it's raining"). The (...) belief puzzles (Hesperus, Cicero, Pierre) involve reports about two different notions. So the analysis gets the puzzling truth values right. (shrink)

Substantial facts are not well-understood entities. Many philosophers object to their existence on this basis. Yet facts, if they can be understood, promise to do a lot of philosophical work: they can be used to construct theories of property possession and truthmaking, for example. Here, I give a formal theory of facts, including negative and logically complex facts. I provide a theory of reduction similar to that of the typed λ -calculus and use it to provide identity conditions for facts. (...) This theory validates truthmaker maximalism : it provides truthmakers for all truths. I then show how the usual truth-in-a-model relation can be replaced by two relations: one between models and facts, saying that a given fact obtains relative to the model, and the other between facts and propositions: the truthmaking relation.

Remembering that there’s a difference between intellectual and perceptual attention can help us avoid miscommunication due to meaning different things by the same terms, which has been a particular problem during the last hundred years or so of the study of attention. I demonstrate this through analyzing in depth one such miscommunication that occurred in a philosophical criticism of the influential psychological text, Inattentional Blindness. But after making the distinction between perceptual attention and intellectual attention, and after making an effort (...) to keep this distinction in mind, we are still faced with the problem of specifying what makes intellectual attention distinct from perceptual attention. In the second half of this article, I discuss the range of proposals about how to understand intellectual attention that are present in the literature, and the problems with them. I do this with the aim of stimulating further discussion about how best to conceptualize intellectual attention, although I do not settle that further question within this paper. (shrink)

Most philosophers find it puzzling how beliefs could wrong, and this leads them to conclude that they do not. So there is much philosophical work to be done in sorting out whether I am right to say that they do, as well as how this could be so. But in this paper I will take for granted that beliefs can wrong, and ask instead when beliefs wrong. My answer will be that beliefs wrong when they falsely diminish. This answer has (...) three parts: that beliefs wrong only when they are false, that beliefs wrong only when they diminish, and that false diminishment is sufficient for wronging. I will seek to elaborate on and defend all three of these claims, but it is the first to which I will give the most attention. (shrink)

Among the powers of living beings are intentional psychic powers, psychic powers that are of something. Thus, there is something seen, just as there is something feared or known. A puzzle arises when we consider whether these psychic powers might also be reflexive. Can these psychic powers be applied to themselves, or at least their exercise, such that the powers themselves, or their exercise, are their intentional objects? So, for example, in seeing what one does, and so being aware from (...) within that one thus sees, does one thereby see the seeing of it? An initial difficulty is that, in a range of familiar cases, the intentional object is distinct from the power and its exercise. The scene is distinct from the sight or seeing of it. Should this be a general feature of intentionality, then intentional powers are irreflexive. There is a potential tension, then, between the intentional character of psychic powers and their alleged reflexivity. This tension forms the basis of a puzzle or aporia that is at the heart of the Charmides. Part of what is at stake here is the coherence of perceptual self-consciousness, at least on an understanding of it. (shrink)

This paper is about whether shifts in attention can alter what it is like to think. I begin by taking up the hypothesis that attention structures consciousness into a centre and a periphery, following Watzl's (2014; 2017) understanding of the distinction between the centre and periphery of the field of consciousness. Then I show that introspection leads to divided results about whether attention structures conscious thought into a centre and a periphery -- remarks by Martin (1997) and Phillips (2012) suggest (...) a negative answer, whereas remarks by Maher (1923) and Chudnoff (2013) suggest a positive answer. Lastly, I argue that there is behavioural evidence that lends weight to the 'yes' side of the introspective dispute. My argument makes use of Garavan's (1998) study of forming and maintaining two mental counts at once. (shrink)

An account of distinctively mathematical explanation (DME) should satisfy three desiderata: it should account for the modal import of some DMEs; it should distinguish uses of mathematics in explanation that are distinctively mathematical from those that are not (Baron [2016]); and it should also account for the directionality of DMEs (Craver and Povich [2017]). Baron’s (forthcoming) deductive-mathematical account, because it is modelled on the deductive-nomological account, is unlikely to satisfy these desiderata. I provide a counterfactual account of DME, the Narrow (...) Ontic Counterfactual Account (NOCA), that can satisfy all three desiderata. NOCA appeals to ontic considerations to account for explanatory asymmetry and ground the relevant counterfactuals. NOCA provides a unification of the causal and the non-causal, the ontic and the modal, by identifying a common core that all explanations share and in virtue of which they are explanatory. (shrink)

Jago uses a Fitch-style argument in an attempt to demonstrate that every truth has a truthmaker. But Trueman shows that there is a parallel argument, this time to the conclusion that no truth has a truthmaker. Since we cannot accept both, we must ditch at least one Fitch. But which? Keywords: Truth, truthmaking, truthmaker maximalism, Fitch paradox, Robert Trueman.

Causation is one of philosophy's most venerable and thoroughly-analyzed concepts. However, the study of how ordinary people make causal judgments is a much more recent addition to the philosophical arsenal. One of the most prominent views of causal explanation, especially in the realm of harmful or potentially harmful behavior, is that unusual or counternormative events are accorded privileged status in ordinary causal explanations. This is a fundamental assumption in psychological theories of counterfactual reasoning, and has been transported to philosophy by (...) Hitchcock and Knobe (2009). A different view--the basis of the culpable control model of blame (CCM)--is that primary causal status is accorded to behaviors that arouse negative evaluative reactions, including behaviors that stem from nefarious motives, negligence or recklessness, a faulty character, or behaviors that lead to harmful or potentially harmful consequences. This paper describes four empirical studies that show consistent support for the CCM. (shrink)

I develop and defend a truthmaker semantics for the relevant logic R. The approach begins with a simple philosophical idea and develops it in various directions, so as to build a technically adequate relevant semantics. The central philosophical idea is that truths are true in virtue of specific states. Developing the idea formally results in a semantics on which truthmakers are relevant to what they make true. A very natural notion of conditionality is added, giving us relevant implication. I then (...) investigate ways to add conjunction, disjunction, and negation; and I discuss how to justify contraposition and excluded middle within a truthmaker semantics. (shrink)

YouTube has been implicated in the transformation of users into extremists and conspiracy theorists. The alleged mechanism for this radicalizing process is YouTube’s recommender system, which is optimized to amplify and promote clips that users are likely to watch through to the end. YouTube optimizes for watch-through for economic reasons: people who watch a video through to the end are likely to then watch the next recommended video as well, which means that more advertisements can be served to them. This (...) is a seemingly innocuous design choice, but it has a troubling side-effect. Critics of YouTube have alleged that the recommender system tends to recommend extremist content and conspiracy theories, as such videos are especially likely to capture and keep users’ attention. To date, the problem of radicalization via the YouTube recommender system has been a matter of speculation. The current study represents the first systematic, pre-registered attempt to establish whether and to what extent the recommender system tends to promote such content. We begin by contextualizing our study in the framework of technological seduction. Next, we explain our methodology. After that, we present our results, which are consistent with the radicalization hypothesis. Finally, we discuss our findings, as well as directions for future research and recommendations for users, industry, and policy-makers. (shrink)

The purpose of this paper is to conceptualize and explore what I shall call the Common Subject Problem for ethics. The problem is that there seems to be no good answer to what property everyone who makes moral claims could be talking and thinking about. The Common Subject Problem is not a new problem; on the contrary, I will argue that it is one of the central animating concerns in the history of both metaethics and normative theory. But despite its (...) importance, the Common Subject Problem is essentially invisible on many contemporary ways of carving up the problems of metaethics and normative ethical theory. My aim, therefore, is to make progress – in part by naming the problem, but also by beginning to sketch out the contours of what gives the problem its force, by distinguishing between different paths of response to the problem and assessing some of their chief merits, and finally, by distinguishing the Common Subject Problem from another problem with which it has come to be conflated. This nearby problem is the Moral Twin Earth Problem. Whereas the Common Subject Problem is a problem about what property ‘wrong’ could refer to, the Moral Twin Earth Problem is a problem about how ‘wrong’ could refer to it. The upshot of the paper, therefore, is to rescue one of the historically significant problems in normative ethics and metaethics – a problem that is essentially about normative semantics – from the illusion that has persisted over the last twenty years that it is really, somehow, a problem about metasemantics. Once we have reclaimed this problem, we can see that it could still be a problem even if there are no distinctively metasemantic problems in metaethics at all, that it is a problem faced by a wider variety of views, and that the space of possible solutions is much wider and more interesting for normative theory, moral psychology, and moral epistemology.

Philosophers have come to distinguish between ‘right’ and ‘wrong’ kinds of reasons for belief, intention, and other attitudes. Several theories about the nature of this distinction have been offered, by far the most prevalent of which is the idea that it is, at bottom, the distinction between what are known as ‘object-given’ and ‘state-given’ reasons. This paper argues that the object-given/state-given theory vastly overgeneralizes on a small set of data points, and in particular that any adequate account of the distinction (...) between the ‘right’ and ‘wrong’ kinds of reason must allow state-given reasons to be of the right kind. The paper has three main goals, corresponding to its three main parts. In part 1 I set up the problem by introducing the right-kind/wrong-kind distinction, the object-given/state-given distinction, and the object-given/state-given theory, according to which the former distinction simply amounts to the latter. Part 2 presents the main argument of the paper: I argue against the object-given/state-given theory by showing that all of the earmarks of the ‘right’ and ‘wrong’ kinds of reason apply to reasons not to intend and not to believe, but that these cases can’t be captured by the object-given/state-given theory. Finally, in part 3 I use these arguments to motivate and explore a more general hypothesis about the rightkind/wrong-kind distinction, and explore some of the consequences of rejecting the object-given/stategiven theory.

Fitting Attitudes accounts of value analogize or equate being good with being desirable, on the premise that ‘desirable’ means not, ‘able to be desired’, as Mill has been accused of mistakenly assuming, but ‘ought to be desired’, or something similar. The appeal of this idea is visible in the critical reaction to Mill, which generally goes along with his equation of ‘good’ with ‘desirable’ and only balks at the second step, and it crosses broad boundaries in terms of philosophers’ other (...) commitments. For example, Fitting Attitudes accounts play a central role both in T.M. Scanlon’s [1998] case against teleology, and in Michael Smith [2003], [unpublished] and Doug Portmore’s [2007] cases for it. And of course they have a long and distinguished history. (shrink)

The basic idea of expressivism is that for some sentences ‘P’, believing that P is not just a matter of having an ordinary descriptive belief. This is a way of capturing the idea that the meaning of some sentences either exceeds their factual/descriptive content or doesn’t consist in any particular factual/descriptive content at all, even in context. The paradigmatic application for expressivism is within metaethics, and holds that believing that stealing is wrong involves having some kind of desire-like attitude, with (...) world-tomind direction of fit, either in place of, or in addition to, being in a representational state of mind with mind-to-world direction of fit. Because expressivists refer to the state of believing that P as the state of mind ‘expressed’ by ‘P’, this view can also be described as the view that ‘stealing is wrong’ expresses a state of mind that involves a desire-like attitude instead of, or in addition to, a representational state of mind. According to some expressivists - unrestrained expressivists, as I’ll call them - there need be no special relationship among the different kinds of state of mind that can be expressed by sentences. Pick your favorite state of mind, the unrestrained expressivist allows, and there could, at least in principle, be a sentence that expressed it. Expressivists who seem to have been unrestrained plausibly include Ayer in Language, Truth, and Logic, and Simon Blackburn in many of his writings, including his [1984], [1993], and.. (shrink)

What is it to have a reason? According to one common idea, the "Factoring Account", you have a reason to do A when there is a reason for you to do A which you have--which is somehow in your possession or grasp. In this paper, I argue that this common idea is false. But though my arguments are based on the practical case, the implications of this are likely to be greatest in epistemology: for the pitfalls we fall into when (...) trying to defend the Factoring Account reflect very well the major developments in empiricist epistemology during the 20th century. I conjecture that this is because epistemologists have been--wrongly--wedded to the Factoring Account about evidence, which I conjecture is a certain kind of reason to believe. (shrink)

The inflation of Type I error rates is thought to be one of the causes of the replication crisis. Questionable research practices such as p-hacking are thought to inflate Type I error rates above their nominal level, leading to unexpectedly high levels of false positives in the literature and, consequently, unexpectedly low replication rates. In this article, I offer an alternative view. I argue that questionable and other research practices do not usually inflate relevant Type I error rates. I begin (...) by introducing the concept of Type I error rates and distinguishing between statistical errors and theoretical errors. I then illustrate my argument with respect to model misspecification, multiple testing, selective inference, forking paths, exploratory analyses, p-hacking, optional stopping, double dipping, and HARKing. In each case, I demonstrate that relevant Type I error rates are not usually inflated above their nominal level, and in the rare cases that they are, the inflation is easily identified and resolved. I conclude that the replication crisis may be explained, at least in part, by researchers’ misinterpretation of statistical errors and their underestimation of theoretical errors. (shrink)

This chapter lays out a case that with the proper perspective on the place of epistemology within normative inquiry more generally, it is possible to appreciate what was on the right track about some of the early approaches to the analysis of knowledge, and to improve on the obvious failures which led them to be rejected. Drawing on more general principles about reasons, their weight, and their relationship to justification, it offers answers to problems about defeat and the conditional fallacy (...) that plagued early defeasibility analyses of knowledge and offers a sketch of a contemporary alternative that is motivated by the idea that knowledge requires the right kind of “match” between objective and subjective factors.

Intentions matter. They have some kind of normative impact on our agency. Something goes wrong when an agent intends some end and fails to carry out the means she believes to be necessary for it, and something goes right when, intending the end, she adopts the means she thinks are required. This has even been claimed to be one of the only uncontroversial truths in ethical theory. But not only is there widespread disagreement about why this is so, there is (...) widespread disagreement about in what sense it is so. In this paper I explore an underdeveloped answer to the question of in what sense it is so, and argue that resolving an apparent difficulty with this view leads to an attractive picture about why it is so.

Each truth has a truthmaker: an entity in virtue of whose existence that truth is true. So say truthmaker maximalists. Arguments for maximalism are hard to find, whereas those against are legion. Most accept that maximalism comes at a significant cost, which many judge to be too high. The scales would seem to be balanced against maximalism. Yet, as I show here, maximalism can be derived from an acceptable premise which many will pre-theoretically accept.

This paper will examine the nature of mechanisms and the distinction between the relevant and irrelevant parts involved in a mechanism’s operation. I first consider Craver’s account of this distinction in his book on the nature of mechanisms, and explain some problems. I then offer a novel account of the distinction that appeals to some resources from Mackie’s theory of causation. I end by explaining how this account enables us to better understand what mechanisms are and their various features.

The Appendix to the Transcendental Dialectic of Kant's first Critique is notorious for two reasons. First, it appears to contradict itself in saying that the idea of the systematic unity of nature is and is not transcendental. Second, in the passages in which Kant appears to espouse the former alternative, he appears to be making a significant amendment to his account of the conditions of the possibility of experience in the Transcendental Analytic. I propose a solution to both of these (...) difficulties. With regard to the first, I argue that Kant does not contradict himself. With regard to the second, I argue that Kant is not making any change to his view of the conditions of the possibility of experience espoused in the Transcendental Analytic. The underlying cause of these apparent problems is also their solution: the transcendental illusion that nature is necessarily systematic. (shrink)

Batterman and Rice ([2014]) argue that minimal models possess explanatory power that cannot be captured by what they call ‘common features’ approaches to explanation. Minimal models are explanatory, according to Batterman and Rice, not in virtue of accurately representing relevant features, but in virtue of answering three questions that provide a ‘story about why large classes of features are irrelevant to the explanandum phenomenon’ ([2014], p. 356). In this article, I argue, first, that a method (the renormalization group) they propose (...) to answer the three questions cannot answer them, at least not by itself. Second, I argue that answers to the three questions are unnecessary to account for the explanatoriness of their minimal models. Finally, I argue that a common features account, what I call the ‘generalized ontic conception of explanation’, can capture the explanatoriness of minimal models. (shrink)

In his contribution, Mark Alfano lays out a new (to virtue theory) naturalistic way of determining what the virtues are, what it would take for them to be realized, and what it would take for them to be at least possible. This method is derived in large part from David Lewis’s development of Frank Ramsey’s method of implicit definition. The basic idea is to define a set of terms not individually but in tandem. This is accomplished by assembling all (...) and only the common sense platitudes that involve them (e.g., typically, people want to be virtuous), conjoining those platitudes, and replacing the terms in question by existentially quantified variables. If the resulting sentence is satisfied, then whatever satisfies are the virtues. If it isn’t satisfied, there are a couple of options. First, one could just admit defeat by saying that people can’t be virtuous. More plausibly, one could weaken the conjunction by dropping a small number of the platitudes from it (and potentially adding some others). Alfano suggests that the most attractive way to do this is by dropping the platitudes that deal with cross-situational consistency and replacing them with platitudes that involve social construction: basically, people are virtuous (when they are) at least in part because other people signal their expectations of virtuous conduct, which induces virtuous conduct, which in turn induces further signals of expected virtuous conduct, and so on.

I know that I could have been where you are right now and that you could have been where I am right now, but that neither of us could have been turnips or natural numbers. This knowledge of metaphysical modality stands in need of explanation. I will offer an account based on our knowledge of the natures, or essencess, of things. I will argue that essences need not be viewed as metaphysically bizarre entities; that we can conceptualise and refer to (...) essences; and that we can gain knowledge of them. We can know about which properties are, and which properties are not, essential to a given entity. This knowledge of essence offers a route to knowledge of the ways those entities must be or could be. (shrink)

Impossible worlds are representations of impossible things and impossible happenings. They earn their keep in a semantic or metaphysical theory if they do the right theoretical work for us. As it happens, a worlds-based account provides the best philosophical story about semantic content, knowledge and belief states, cognitive significance and cognitive information, and informative deductive reasoning. A worlds-based story may also provide the best semantics for counterfactuals. But to function well, all these accounts need use of impossible and as well (...) as possible worlds. So what are impossible worlds? Graham Priest claims that any of the usual stories about possible worlds can be told about impossible worlds, too. But far from it. I'll argue that impossible worlds cannot be genuine worlds, of the kind proposed by Lewis, McDaniel or Yagisawa. Nor can they be ersatz worlds on the model proposed by Melia or Sider. Constructing impossible worlds, it turns out, requires novel metaphysical resources. (shrink)
