I defend the principle of Phenomenal Conservatism, on which appearances of all kinds generate at least some justification for belief. I argue that there is no reason for privileging introspection or intuition over perceptual experience as a source of justified belief; that those who deny Phenomenal Conservatism are in a self-defeating position, in that their view cannot be both true and justified; and that thedemand for a metajustification for Phenomenal Conservatism either is an easily met demand, or is an unfair (...) or question-begging one.

Debunking skeptics claim that our moral beliefs are formed by processes unsuited to identifying objective facts, such as emotions inculcated by our genes and culture; therefore, they say, even if there are objective moral facts, we probably don’t know them. I argue that the debunking skeptics cannot explain the pervasive trend toward liberalization of values over human history, and that the best explanation is the realist’s: humanity is becoming increasingly liberal because liberalism is the objectively correct moral stance.

Parsimony is a virtue of empirical theories. Is it also a virtue of philosophical theories? I review four contemporary accounts of the virtue of parsimony in empirical theorizing, and consider how each might apply to two prominent appeals to parsimony in the philosophical literature, those made on behalf of physicalism and on behalf of nominalism. None of the accounts of the virtue of parsimony extends naturally to either of these philosophical cases. This suggests that in typical philosophical contexts, ontological simplicity (...) has no evidential value. (shrink)

I argue that, given evidence of the factors that tend to distort our intuitions, ethical intuitionists should disown a wide range of common moral intuitions, and that they should typically give preference to abstract, formal intuitions over more substantive ethical intuitions. In place of the common sense morality with which intuitionism has traditionally allied, the suggested approach may lead to a highly revisionary normative ethics.

I defend the 'Repugnant' Conclusion that for any possible population of happy people, a population containing a sufficient number of people with lives barely worth living would be better. Four lines of argument converge on this conclusion, and the conclusion has a simple, natural theoretical explanation. The opposition to the Repugnant Conclusion rests on a bare appeal to intuition. This intuition is open to charges of being influenced by multiple distorting factors. Several theories of population ethics have been devised to (...) avoid the Repugnant Conclusion, but each generates even more counterintuitive consequences. The intuition opposing the Repugnant Conclusion is thus among the best candidates for an intuition that should be revised. (shrink)

Externalist theories of justification create the possibility of cases in which everything appears to one relevantly similar with respect to two propositions, yet one proposition is justified while the other is not. Internalists find this difficult to accept, because it seems irrational in such a case to affirm one proposition and not the other. The underlying internalist intuition supports a specific internalist theory, Phenomenal Conservatism, on which epistemic justification is conferred by appearances.

Time may be infinite in both directions. If it is, then, if persons could live at most once in all of time, the probability that you would be alive now would be zero. But if persons can live more than once, the probability that you would be alive now would be nonzero. Since you are alive now, with certainty, either the past is finite, or persons can live more than once.

We propose that all actual causes are simultaneous with their direct effects, as illustrated by both everyday examples and the laws of physics. We contrast this view with the sequential conception of causation, according to which causes must occur prior to their effects. The key difference between the two views of causation lies in differing assumptions about the mathematical structure of time.

We provide a cognitive analysis of how children represent belief using mental files. We explain why children who pass the false belief test are not aware of the intensionality of belief. Fifty-one 3½- to 7-year old children were familiarized with a dual object, e.g., a ball that rattles and is described as a rattle. They observed how a puppet agent witnessed the ball being put into box 1. In the agent’s absence the ball was taken from box 1, the child (...) was reminded of it being a rattle, and emphasising its being a rattle it was put back into box 1. Then the agent returned, the object was hidden in the experimenter’s hands and removed from box 1, described as a ‘‘rattle,” and transferred to box 2. Children who passed false belief had no problem saying where the puppet would look for the ball. However, in a different condition in which the agent was also shown that the ball was a rattle they erroneously said that the agent would look for the ball in box 1, ignoring the agent’s knowledge of the identity of rattle and ball. Their problems cease with their mastery of second-order beliefs. Problems also vanish when the ball is described not as a rattle but as a thing that rattles. We describe how our theory can account for these data as well as all other relevant data in the literature. (shrink)

Skeptical hypotheses such as the brain-in-a-vat hypothesis provide extremely poor explanations for our sensory experiences. Because these scenarios accommodate virtually any possible set of evidence, the probability of any given set of evidence on the skeptical scenario is near zero; hence, on Bayesian grounds, the scenario is not well supported by the evidence. By contrast, serious theories make reasonably specific predictions about the evidence and are then well supported when these predictions are satisfied.

The justificatory force of empirical reasoning always depends upon the existence of some synthetic, a priori justification. The reasoner must begin with justified, substantive constraints on both the prior probability of the conclusion and certain conditional probabilities; otherwise, all possible degrees of belief in the conclusion are left open given the premises. Such constraints cannot in general be empirically justified, on pain of infinite regress. Nor does subjective Bayesianism offer a way out for the empiricist. Despite often-cited convergence theorems, subjective (...) Bayesians cannot hold that any empirical hypothesis is ever objectively justified in the relevant sense. Rationalism is thus the only alternative to an implausible skepticism. (shrink)

The essay argues that while there is no general agreement on whether moral realism is true, there is general agreement on at least some of the moral obligations that we have if moral realism is true. Given that moral realism might be true, and given that we know some of the things we ought to do if it is true, we have a reason to do those things. Furthermore, this reason is itself an objective moral reason. Thus, if moral realism (...) might be true, then it is true. (shrink)

Abstract: In earlier work, I argued that individuals have a right to own firearms for personal defense, and that as a result, gun prohibition would be unjustified unless it at least produced benefits many times greater than its costs. Here, I defend that argument against objections posed by Nicholas Dixon and Jeff McMahan to the effect that the right of citizens to be free from gun violence counterbalances the right of self-defense, and that gun prohibition does not violate the right (...) of self-defense because it renders everyone overall safer.

I argue that taxation for redistributive purposes is a property rights violation, responding to arguments (due to Nagel, Murphy, Sunstein, and Holmes) claiming that individuals lack ownership of their pretax incomes.

In the practice of jury nullification, a jury votes to acquit a defendant in disregard of the factual evidence, on the grounds that a conviction would result in injustice, either because the law itself is unjust or because its application in the particular case would be unjust. The practice is widely condemned by courts, which strenuously attempt to prevent it. Nevertheless, the arguments against jury nullification are surprisingly weak. I argue that, pursuant to the general ethical duty to avoid causing (...) unjust harms to others, jurors are often morally obligated to disregard the law. (~7400 words). (shrink)

Deontological ethicists generally agree that there is a way of harming others such that it is wrong to harm others in that way for the sake of producing a comparable but greater benefit for others. Given plausible assumptions about this type of harm, this principle yields the paradoxical result that it may be wrong to do A, wrong to do B, but permissible to do (A and B).

Jury nullification is justified by the principle that individuals are prima facie ethically obligated to avoid causing unjust harms. Safeguarding justice against unjust laws and punishments of the government is the central function of the jury.

Den Beteiligten des Politikbetriebs einschließlich Wählern, Aktivisten und Spitzenpolitikern fehlt häufig der grundlegende Sachverstand für die jeweiligen politischen Entscheidungen. Selbst Experten verstehen gesellschaftliche Mechanismen kaum und können deren Auswirkung kaum vorhersagen. Nur auf einfachste und unstrittige politische Behauptungen ist Verlass. Teilweise rührt das daher, dass politisches Wissen schwer zu erlangen ist, und teilweise daher, dass der Einzelne keinen ausreichenden Ansporn hat, es zu erlangen. Demzufolge besteht der beste Ratschlag an die politischen Akteure sehr häufig schlicht darin, gesellschaftliche Probleme nicht anzugehen, (...) zumal Eingriffe, die nicht auf einem genauen Verständnis beruhen, vermutlich mehr Schaden als Nutzen anrichten. -/- [This is a German translation of "In Praise of Passivity".

Soll der Freizeitkonsum von Drogen wie Marihuana, Kokain, Heroin und LSD einem gesetzlichen Verbot unterliegen? Drogengegner sagen ja. Sie behaupten für gewöhnlich, Drogenkonsum sei sowohl für den Nutzer als auch für die Gesellschaft allgemein äußerst schädlich – vielleicht sogar unmoralisch, und sie glauben, diese Tatsachen seien als Verbotsgrund ausreichend. Freigabebefürworter sagen nein und berufen sich dabei für gewöhnlich auf eines oder mehrere von drei Argumenten: Erstens behaupten einige, Drogenkonsum sei nicht so schädlich, wie Drogengegner meinen, und sei gelegentlich sogar nützlich. (...) Zweitens behaupten einige, Drogenverbote „funktionierten“ nicht, d. h. sie verhinderten den Drogenkonsum nicht besonders wirksam und hätten eine Reihe sehr nachteiliger Folgewirkungen. Schließlich behaupten einige, Drogenverbote seien Unrecht oder verletzten Rechte. -/- Ich unternehme an dieser Stelle nicht den Versuch, all diese Argumente zu besprechen. Stattdessen beschränke ich mich auf die drei Hauptargumente der Drogendebatte: Erstens demjenigen, Drogen solle man aufgrund der Schädigung der Konsumenten verbieten; zweitens, man solle sie verbieten, weil sie außer den Konsumenten noch anderen schadeten; und drittens, man solle sie legalisieren, weil Drogenverbote Rechte verletzten. Ich richte mein Augenmerk auf die moralphilosophischen Fragen, welche diese Argumente aufwerfen, statt auf medizinische oder gesellschaftliche Fragen und werde zeigen, dass die beiden Verbotsargumente scheitern, wogegen das dritte Argument für die Freigabe greift. -/- [This is a German translation of "America's Unjust Drug War".

In a recent paper, Michael Huemer provides a new interpretation for ‘N’, the operator that occurs in Peter van Inwagen’s Consequence Argument, and argues that, given that interpretation, the Consequence Argument is sound. I have no quarrel with Huemer’s claim that the Consequence Argument is valid. I shall argue instead that his defense of its premises—a defense that allegedly involves refuting David Lewis’s response to van Inwagen—is unsuccessful.

In this paper, I respond to Michael Huemer’s reply to my objection against Phenomenal Conservatism (PC). I have argued that Huemer’s Self-defeat Argument for PC does not favor PC over competing theories of basic propositional justification, since analogous self-defeat arguments can be constructed for competing theories. Huemer responds that such analogous self-defeat arguments are unsound. In this paper, I argue that Huemer’s reply does not save his Self-defeat Argument for PC from my original objection.

This chapter discusses the nature and value of political disagreement, with reference to contemporary work in political philosophy. I will attempt to answer the following questions: Why do we disagree? Is political disagreement a good thing? Do we have a duty to disagree? Should we expect consensus or mere compromise in politics? When is civil disobedience a justified way to express disagreement with the law? Is consensus a threat to democracy?

I review recent work on Phenomenal Conservatism, the position introduced by Michael Huemer according to which if it seems that P to a subject S, in the absence of defeaters S has thereby some degree of justification for believing P.

They give the latest word on such topics as identity, modality, time, causation, persons and minds, freedom, and vagueness. The Handbook's unrivaled breadth and depth make it the definitive reference work (...) for students and academics across the philosophical spectrum. (shrink)

The notion of beauty has endured a troublesome history over the last few decades. While for centuries beauty has been considered one of the central values of art, there have also been times when it seemed old-fashioned to even mention the term. The present volume aims to explore the nature of beauty and to shed light its place in contemporary philosphy and art practice.

What do we see in a mirror? There is an ongoing debate whether mirrors present us with images of objects or whether we see, through the mirror, the objects themselves. Roberto Casati has recently argued that there is a categorical difference between images and mirror-reflections. His argument depends on the observation that mirrors, but not paintings, are sensitive to changes in the observer’s prospective. In our paper we scrutinize Casati’s argument and present a modal argument that shows that it cannot (...) establish this conclusion. We suggest that Casati’s line of reasoning suffers from the fact that he does not take dynamic images, i.e., images that change over time, into account. (shrink)

Epistemic decision theory produces arguments with both normative and mathematical premises. I begin by arguing that philosophers should care about whether the mathematical premises (1) are true, (2) are strong, and (3) admit simple proofs. I then discuss a theorem that Briggs and Pettigrew (2020) use as a premise in a novel accuracy-dominance argument for conditionalization. I argue that the theorem and its proof can be improved in a number of ways. First, I present a counterexample that shows that one (...) of the theorem’s claims is false. As a result of this, Briggs and Pettigrew’s argument for conditionalization is unsound. I go on to explore how a sound accuracy-dominance argument for conditionalization might be recovered. In the course of doing this, I prove two new theorems that correct and strengthen the result reported by Briggs and Pettigrew. I show how my results can be combined with various normative premises to produce sound arguments for conditionalization. I also show that my results can be used to support normative conclusions that are stronger than the one that Briggs and Pettigrew’s argument supports. Finally, I show that Briggs and Pettigrew’s proofs can be simplified considerably. (shrink)

This paper defends a theory of hope according to which hopes are composed of a desire and a belief that the object of the desire is possible. Although belief plus desire theories of hope are now widely rejected, this is due to important oversights. One is a failure to recognize the relation that hope-constituting desires and beliefs must stand in to constitute a hope. A second is an oversimplification of the explanatory power of hope-constituting desires. The final portion of the (...) paper uses an enhanced understanding of the psychology of hope to make progress on normative questions about hoping well. (shrink)

According to a historically popular view, emotions are normative experiences that ground moral knowledge much as perceptual experiences ground empirical knowledge. Given the analogy it draws between emotion and perception, sentimental perceptualism constitutes a promising, naturalist-friendly alternative to classical rationalist accounts of moral knowledge. In this paper, we consider an important but underappreciated objection to the view, namely that in contrast with perception, emotions depend for their occurrence on prior representational states, with the result that emotions cannot give perceptual-like access (...) to normative properties. We argue that underlying this objection are several specific problems, rooted in the different types of mental states to which emotions may respond, that the sentimental perceptualist must tackle for her view to be successful. We argue, moreover, that the problems can be answered by filling out the theory with several independently motivated yet highly controversial commitments, which we carefully catalogue. The plausibility of sentimental perceptualism, as a result, hinges on further claims sentimental perceptualists should not ignore. (shrink)

The fact that Gilbert Ryle and J.L. Austin seem to disagree about the ordinary use of words such as ‘voluntary’, ‘involuntary’, ‘voluntarily’, and ‘involuntarily’ has been taken to cast doubt on the methods of ordinary language philosophy. As Benson Mates puts the worry, ‘if agreement about usage cannot be reached within so restricted a sample as the class of Oxford Professors of Philosophy, what are the prospects when the sample is enlarged?’ (Mates, Inquiry 1:161–171, 1958, p. 165). In this chapter, (...) we evaluate Mates’s criticism alongside Ryle’s and Austin’s specific claims about the ordinary use of these words, assessing these claims against actual examples of ordinary use drawn from the British National Corpus (BNC). Our evaluation consists in applying a combination of methods: first aggregating judgments about a large set of samples drawn from the corpus, and then using a clustering algorithm to uncover connections between different types of use. In applying these methods, we show where and to what extent Ryle’s and Austin’s accounts of the use of the target terms are accurate as well as where they miss important aspects of ordinary use, and we demonstrate the usefulness of this new combination of methods. At the heart of our approach is a commitment to the idea that systematically looking at actual uses of expressions is an essential component of any approach to ordinary language philosophy. (shrink)

This paper offers a qualified defense of a historically popular view that I call sentimental perceptualism. At a first pass, sentimental perceptualism says that emotions play a role in grounding evaluative knowledge analogous to the role perceptions play in grounding empirical knowledge. Recently, András Szigeti and Michael Brady have independently developed an important set of objections to this theory. The objections have a common structure: they begin by conceding that emotions have some important epistemic role to play, but then (...) go on to argue that understanding how emotions play that role means that there must be some alternative, emotion-independent route to obtaining knowledge of value. If there has to be such an emotion-independent route, then the perceptual analogy breaks down in a significant way. In this paper, I argue that the right ways for sentimental perceptualists to respond to each of these objections are revealed by thinking through how analogous objections applied to perception and the empirical domain would be answered. Although Szigeti's and Brady's objections should not persuade sentimental perceptualists to give up their view, the objections do put important constraints on what a form of the view has to be like in order to do exciting metaethical work.

The first argument that Hume offers against believing in miracle stories in Part 2 of his essay on miracles relies on social context in a way that makes it difficult to follow. Hume says that there’s never been a miracle story that’s well enough attested with respect to certain criteria of testimonial strength. A little later in the essay, he cites recent miracle stories coming from that Saint Médard cemetery as meeting the criteria to an exceptionally high degree, but even (...) so, he claims that we can dismiss the stories out of hand. The hidden background assumption is that his Protestant readers wouldn’t have been tempted to believe in miracle stories coming from an oppressed Catholic sect. Other examples in Part 2 of the essay work in the same way. Hume praises to the skies the quality of the evidence for an earlier Jansenist miracle, for a miracle involving the restoration of a leg through holy water at a Catholic cathedral, and a miracle at a temple of Serapis knowing that his readers won’t be inclined to believe in any of them. The point is that these miracles are better attested than the miracle stories in the Bible, and if we shouldn’t believe in the better attested stories, then we shouldn’t believe in the worse. This can seem like an appeal to prejudice, but really Hume is doing something subtler. He knows that it’s easier to criticize the irrational beliefs of others, but sees that once we turn the same standards that we use on others on our own beliefs, epistemic progress is possible.

Call "radical moral theorizing" the project of developing a moral theory that not only tries to conform to our existing moral intuitions, but also manifests various theoretical virtues: consistency, simplicity, explanatory depth, and so on. Many moral philosophers assume that radical moral theorizing does not require any particular metaethical commitments. In this paper, I argue against this assumption. The most natural justification for radical moral theorizing presupposes moral realism, broadly construed; in contrast, there may be no justification for radical moral (...) theorizing if moral anti-realism is true.

In the present article, he explains why divine silence poses a serious intellectual obstacle to belief in God, and then goes on to consider ways of overcoming that obstacle. After considering several ways in which divine silence might actually be beneficial to human beings, he argues that perhaps silence is nothing more or less than God’s preferred mode of interaction with creatures like us. Perhaps God simply desires communion rather than overt communication with human beings, and perhaps God has provided (...) ways for us to experience God’s presence richly even amidst the silence.

What role does the imagination play in scientific progress? After examining several studies in cognitive science, I argue that one thing the imagination does is help to increase scientific understanding, which is itself indispensable for scientific progress. Then, I sketch a transcendental justification of the role of imagination in this process.

The ‘black box’ in Stoic axiology refers to the mysterious connection between the input of Stoic deliberation (reasons generated by the value of indifferents) and the output (appropriate actions). In this paper, I peer into the black box by drawing an analogy between Stoic and Kantian axiology. The value and disvalue of indifferents is intrinsic, but conditional. An extrinsic condition on the value of a token indifferent is that one's selection of that indifferent is sanctioned by context-relative ethical principles. The (...) value of an indifferent that does not meet this condition is normatively silenced, such that it fails to constitute a reason for action. (shrink)

Scholars, journalists, and activists working on climate change often distinguish between “individual” and “structural” approaches to decarbonization. The former concern choices individuals can make to reduce their “personal carbon footprint” (e.g., eating less meat). The latter concern changes to institutions, laws, and other social structures. These two approaches are often framed as oppositional, representing a mutually exclusive forced choice between alternative routes to decarbonization. After presenting representative samples of this oppositional framing of individual and structural approaches in environmental communication, we (...) identify four problems with oppositional thinking and propose five ways to conceive of individual and structural reform as symbiotic and interdependent.

In Sections 1–7, I provide a detailed description of some of the advantages of theistic modal realism. The aim is to show specifically how theistic modal realism solves many of the intractable problems of philosophical theology. A detailed description of all of the advantages would require a much longer treatment. The aim is to give a good sense of the theoretical benefits that theistic modal realism affords traditional theists. I offer some concluding remarks in Section 8.

Defends Kantian paternalism: Interference with an individual’s liberty for her own sake is justified absent her actual consent only to the extent that such interference stands a reasonable chance of preventing her from exercising her liberty irrationally in light of the rationally chosen ends that constitute her conception of the good.

This paper asks whether there is a moral virtue of hope, and if so, what it is. The enterprise is motivated by a historical asymmetry, namely that while Christian thinkers have long classed hope as a theological virtue, it has not traditionally been classed as a moral one. But this is puzzling, for hoping well is not confined to the sphere of religion; and consequently we might expect that if the theological virtue is structurally sound, there will be a secular, (...) moral analogue. This paper proposes that there is such an analogue, and that it is closely linked to the everyday notion of “having your priorities straight,” a phenomenon which is naturally understood in terms of the attitude of hope. It turns out that the priorities model provides an abstract way of characterizing a central but underexplored virtue, one which can be developed in secular or theological ways. (shrink)
