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.

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.

It is now generally understood that constraints play an important role in commonsense moral thinking and generally accepted that they cannot be accommodated by ordinary, traditional consequentialism. Some have seen this as the most conclusive evidence that consequentialism is hopelessly wrong,1 while others have seen it as the most conclusive evidence that moral common sense is hopelessly paradoxical.2 Fortunately, or so it is widely thought, in the last twenty-five years a new research program, that of Agent-Relative Teleology, has come to (...) the rescue on all sides. While consequentialism says that every agent ought always to do that action that will bring about the most good, according to Agent- Relative Teleology. (shrink)

This paper is a survey of recent ‘hybrid’ approaches to metaethics, according to which moral sentences, in some sense or other, express both beliefs and desires. I try to show what kinds of theoretical issues come up at the different choice points we encounter in developing such a view, to raise some problems and explain where they come from, and to begin to get a sense for what the payoff of such views can be, and what they will need to (...) do in order to earn that payoff.

Reasons, it is often said, are king in contemporary normative theory. Some philosophers say not only that the vocabulary of reasons is useful, but that reasons play a fundamental explanatory role in normative theory—that many, most, or even all, other normative facts are grounded in facts about reasons. Even if reasons fundamentalism, the strongest version of this view, has only been wholeheartedly endorsed by a few philosophers, it has a kind of prominence in contemporary normative theory that suits it to (...) be described as orthodoxy by its critics. It is the purpose of this paper to make progress toward understanding what appeal Reasons Fundamentalism should have, and whether that appeal is deserved. I will do so by exploring and comparing two central motivations for Reasons Fundamentalism. (shrink)

This paper addresses the question: ‘what makes reasons sufficient?’ and offers the answer, ‘being at least as weighty as the reasons for the alternatives’. The paper starts by introducing some of the reasons why sufficiency has seemed difficult to understand, particularly in epistemology, and some circumstantial evidence that this has contributed to more general problems in the epistemological literature. It then introduces the positive account of sufficiency, and explains how this captures sufficiency in both the practical and epistemic domains. Finally, (...) the paper shows how once we understand the nature of sufficiency, it is easy to predict the full variety of ways in which rationality – both of action and of belief – can be defeated.

Many scholars agree that the Internet plays a pivotal role in self-radicalization, which can lead to behaviours ranging from lone-wolf terrorism to participation in white nationalist rallies to mundane bigotry and voting for extremist candidates. However, the mechanisms by which the Internet facilitates self-radicalization are disputed; some fault the individuals who end up self-radicalized, while others lay the blame on the technology itself. In this paper, we explore the role played by technological design decisions in online self-radicalization in its myriad (...) guises, encompassing extreme as well as more mundane forms. We begin by characterizing the phenomenon of technological seduction. Next, we distinguish between top-down seduction and bottom-up seduction. We then situate both forms of technological seduction within the theoretical model of dynamical systems theory. We conclude by articulating strategies for combatting online self-radicalization.

This book has a noble aim: to free virtue ethics from the grip of the neo- Aristotelianism that limits its scope in contemporary Anglophone philosophy. Just as there are deontological views that are not Kant’s or even Kantian, just as there are consequentialist views that are not Bentham’s or even utilitarian, so, Swanton contends, there are viable virtue ethical views that are not Aristotle’s or even Aristotelian. Indeed, the history of both Eastern and Western philosophy suggests that the majority of (...) normative ethics has focused primarily on under- standing and explaining the nature and development of virtue and vice. There are other alternatives to Aristotle (Mengzi springs to mind), but it’s not unreasonable to start with Hume and Nietzsche, as has already been demonstrated by Erin Frykholm (“A Humean Particularist Virtue Ethic,” Philosophical Studies 172 [2015]: 2171–91) and myself (Mark Alfano, “The Most Agreeable of All Vices,” British Journal for the History of Philosophy 21 [2013]: 767–90).

Burgess (1997), building on Quine (1953), convincingly argued that claims in quantified modal logic cannot be understood as synonymous with or logically equivalent to claims about the analyticity of certain sentences. According to modal normativism, metaphysically necessary claims instead express or convey our actual semantic rules. In this paper, I show how the normativist can use Sidelle’s (1992a, 1995) neglected work on rigidity to account for two important phenomena in quantified modal logic: the necessity of identity and the substitutivity of (...) identicals into modal contexts.

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)

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 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)

Nondescriptivist views in many areas of philosophy have long been associated with the commitment that in contrast to other domains of discourse, there are no propositions in their particular domain. For example, the ‘no truth conditions’ theory of conditionals1 is understood as the view that conditionals don’t express propositions, noncognitivist expressivism in metaethics is understood as advocating the view that there are not really moral propositions,2 and expressivism about epistemic modals is thought of as the view that there is no (...) such thing as the proposition that Jack might be at home, over and above the proposition that Jack is at home.3 Of course, it is nearly always acknowledged that advocates of a nondescriptivist theory need not deny that there are conditional, moral, or modal propositions ‘at the end of the day’ – for if they also endorse a deflationary reading of talk about propositions, as famously advocated by Simon Blackburn, then they can employ such deflationary talk just as much as the rest of us. They just don’t appeal to propositions to do any of the work in their theories. Rather, they ‘earn the right’ to talk about propositions.4 It is the aim of this paper to upset this way of thinking about the proper attitude of nondescriptivists toward propositions, and to advocate a more constructive and in some ways more radical alternative on behalf of the nondescriptivist. I will begin by introducing and developing a set of problems that are faced by any nondescriptivist theory which tries to do without propositions. All of these problems are easily solved by any view which postulates propositions across the board, but none of them are solved by merely deflationary talk about propositions – their most promising solutions require propositions to do real theoretical work, and therefore the problems themselves remind us of and illustrate some of the important reasons why it is worth positing propositions in the first place..

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)

Real-world agents do not know all consequences of what they know. But we are reluctant to say that a rational agent can fail to know some trivial consequence of what she knows. Since every consequence of what she knows can be reached via chains of trivial cot be dismissed easily, as some have attempted to do. Rather, a solution must give adequate weight to the normative requirements on rational agents’ epistemic states, without treating those agents as mathematically ideal reasoners. I’ll (...) argue that agents can fail to know trivial consequences of what they know, but never determinately. Such cases are epistemic oversights on behalf of the agent in question, and the facts about epistemic oversights are always indeterminate facts. As a result, we are never in a position to assert that such-and-such constitutes an epistemic oversight for agent i (for we may rationally assert only determinate truths). I then develop formal epistemic models according to which epistemic accessibility relations are vague. Given these models, we can show that epistemic oversights always concern indeterminate cases of knowledge. (shrink)

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.

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)

This paper addresses the two extensional objections to the Humean Theory of Reasons—that it allows for too many reasons, and that it allows for too few. Although I won’t argue so here, manyof the other objections to the Humean Theoryof Reasons turn on assuming that it cannot successfully deal with these two objections.1 What I will argue, is that the force of the too many and the too few objections to the Humean Theorydepend on whether we assume that Humeans are (...) committed to a thesis about the weight of reasons—one I call Proportionalism. In particular, I’ll show how a version of the Humean Theorythat rejects Proportionalism can reasonablyhope to escape both the too many and the too few objections. This will constitute my defense of this version of the Humean Theory. But then, separately, I will argue that this defense of the Humean Theoryis not ad hoc. I’ll argue that Humeans have no reason to accept Proportionalism in the first place. Or at least, no weightyone. There are three parts to the paper. In Part 1 we introduce the Humean Theoryand the too few reasons objection. I’ll first layout the objection, and then layout the basis for a response on behalf of myfavored version of the Humean Theory. There will be an obvious objection to my defense— but it will turn out to depend on the assumption of Proportionalism. This will constitute myargument that the susceptibilityof the Humean Theoryto..

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)

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)

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)

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)

This is a rough draft of a critical notice of Sergio Tenenbaum’s book, Appearances of the Good, for Social Theory and Practice.

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)

The replication crisis has caused researchers to distinguish between exact replications, which duplicate all aspects of a study that could potentially affect the results, and direct replications, which duplicate only those aspects of the study that are thought to be theoretically essential to reproduce the original effect. The replication crisis has also prompted researchers to think more carefully about the possibility of making Type I errors when rejecting null hypotheses. In this context, the present article considers the utility of two (...) types of Type I error probability: the Neyman–Pearson long run Type I error rate and the Fisherian sample-specific Type I error probability. It is argued that the Neyman–Pearson Type I error rate is inapplicable in social science because it refers to a long run of exact replications, and social science deals with irreversible units that make exact replications impossible. Instead, the Fisherian sample-specific Type I error probability is recommended as a more meaningful way to conceptualize false positive results in social science because it can be applied to each sample-specific decision about rejecting the same substantive null hypothesis in a series of direct replications. It is concluded that the replication crisis may be partly due to researchers’ unrealistic expectations about replicability based on their consideration of the Neyman–Pearson Type I error rate across a long run of exact replications.

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.

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.

Buck-passers about value accept two theses about value, a negative thesis and a positive. The negative thesis is that the fact that something is valuable is not itself a reason to promote or appreciate it. The positive thesis is that the fact that something is valuable consists in the fact that there are other reasons to promote or appreciate it. Buck-passers suppose that the negative thesis follows from the positive one, and sometimes insist on it as if it is the (...) central part of their view. But as I'll explain here, what we say about the negative thesis is orthogonal to what we say about the positive one. (shrink)

Because obituaries are succinct and explicitly intended to summarize their subjects’ lives, they may be expected to include only the features that the author finds most salient but also to signal to others in the community the socially-recognized aspects of the deceased’s character. We begin by reviewing studies 1 and 2, in which obituaries were carefully read and labeled. We then report study 3, which further develops these results with a semi-automated, large-scale semantic analysis of several thousand obituaries. Geography, gender, (...) and elite status all turn out to be associated with the virtues and values associated with the deceased. (shrink)

Philosophers have tended to construe friendship as an intimate relationship involving mutual love, and have focused their discussions on this ‘true’ form of friendship. However, everyone recognizes that we use the word ‘friend’ and its cognates to refer, non-ironically, to those with whom we share various relationships that are not terribly intimate or which do not involve mutual love. I argue that there exists no general reason to restrict our philosophical focus to ‘true’ friendships, and allege that we can gain (...) important insights if we broaden our perspective to include lesser friends. I contend that friendships, in the broad sense (encompassing both ‘true’ and lesser forms), are necessarily relationships that are the product of significant collaborative norm manipulation. And I argue that understanding friendship in this way helps explain important features, including the difference between friendships and familiar relations, the non-fungibility of friends, and why friendships are often in flux.

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.

We sketch the mechanistic approach to levels, contrast it with other senses of “level,” and explore some of its metaphysical implications. This perspective allows us to articulate what it means for things to be at different levels, to distinguish mechanistic levels from realization relations, and to describe the structure of multilevel explanations, the evidence by which they are evaluated, and the scientific unity that results from them. This approach is not intended to solve all metaphysical problems surrounding physicalism. Yet it (...) provides a framework for thinking about how the macroscopic phenomena of our world are or might be related to its most fundamental entities and activities. (shrink)

In the 1960s, Peter Geach and John Searle independently posed an important objection to the wide class of 'noncognitivist' metaethical views that had at that time been dominant and widely defended for a quarter of a century. The problems raised by that objection have come to be known in the literature as the Frege-Geach Problem, because of Geach's attribution of the objection to Frege's distinction between content and assertoric force, and the problem has since occupied a great deal of the (...) attention both of defenders of broadly noncognitivist views, and of their critics. In this article I explain Geach and Searle's historical objections, and put the subsequent discussion into dialectical context, paying some attention to the developments along the way and how they have enhanced our overall understanding of the problem. The article covers a lot of territory, so we will only be able to see the highlights, along the way. For further reading, see the Works Cited. (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)

Allow me to rehearse a familiar scenario. We all know that which ends you have has something to do with what you ought to do. If Ronnie is keen on dancing but Bradley can’t stand it, then the fact that there will be dancing at the party tonight affects what Ronnie and Bradley ought to do in different ways. In short, (HI) you ought, if you have the end, to take the means. But now trouble looms: what if you have (...) dreadful, murderous ends? Ought you to take the means to them? Seemingly not. But fortunately, an assumption made by deontic logics1 comes to the rescue. Since ‘‘ought’’, according to this assumption, is a sentential operator, HI must really be ambiguous. It could be read either as (Narrow) You have the end ! O(you take the means) or as (Wide) O(you have the end ! you take the means). Now if Narrow is true, then you really ought to take the means to your murderous ends. But this doesn’t follow from Wide. All that follows from Wide is that you ought to either take the means to these ends or else give them up. Conclusions: (1) Since HI is on some reading true, but Narrow isn’t, Wide is true. (2) Wide accounts for the relationship between your ends and what you ought to do. This elegant scenario repeats itself in many other domains in which it seems like something can have a bearing on what some particular agent ought to do. Does what you know affect what you ought to do? Do your beliefs about what you ought to do affect what you ought to do? Do your promises affect what you ought to do? Do your beliefs affect what you ought to believe? On each of these counts, the intuitive answer is ‘‘yes’’. And so each of these questions leaves something for the moral philosopher or the epistemologist to investigate. On each count, it seems that what we all know, is that (Account) you ought, if p, to do A. But on each count, the Narrow-scope reading of the ‘‘ought’’ in this claim yields unintuitive consequences. So since Account is true, it must be true on the Wide-scope reading.. (shrink)

Virtues are dispositions that make their bearers admirable. Dispositions can be studied scientifically by systematically varying whether their alleged bearers are in (or take themselves to be in) the dispositions' eliciting conditions. In recent decades, empirically-minded philosophers looked to social and personality psychology to study the extent to which ordinary humans embody dispositions traditionally considered admirable in the Aristotelian tradition. This led some to conclude that virtues are not attainable ideals, and that we should focus our ethical reflection and efforts (...) more on jerry-rigging our environments than on improving our characters. Most virtue ethicists resisted this reorientation. However, much of the scientific evidence on which the controversy was based has failed to replicate, raising the question of how much faith we should place in methodologically suspect studies. In this paper, I assess the state of the debate and recommend best practices for a renewed interdisciplinary investigation of virtues and vices in which philosophical expertise related to conceptualization and theorizing is essentially intertwined with scientific expertise related to operationalization, measurement, and statistics.

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)
