Suppose that you prefer A to B, B to C, and C to A. Your preferences violate Expected Utility Theory by being cyclic. Money-pump arguments offer a way to show that such violations are irrational. Suppose that you start with A. Then you should be willing to trade A for C and then C for B. But then, once you have B, you are offered a trade back to A for a small cost. Since you prefer A to B, (...) you pay the small sum to trade from B to A. But now you have been turned into a money pump. You are back to the alternative you started with but with less money. This Element shows how each of the axioms of Expected Utility Theory can be defended by money-pump arguments of this kind. The Element also defends money-pump arguments from the standard objections to this kind of approach. This title is also available as Open Access on Cambridge Core. (shrink)

Leibniz often refers to the Principle of Sufficient Reason (PSR) as something like a first principle. In some texts, however, he attempts to give positive arguments in its favor. I examine two such arguments, and find them wanting. The first argument has two defects. First, it is question-begging; and second, when the question-begging step is excised, the principle one can in fact derive is highly counter-intuitive. The second argument is valid, but has the defect of only reaching a (...) nearly trivial conclusion. (shrink)

Despite the vast literature on Rawls's work, few have discussed his arguments for the value of democracy. When his arguments have been discussed, they have received staunch criticism. Some critics have charged that Rawls's arguments are not deeply democratic. Others have gone further, claiming that Rawls's arguments denigrate democracy. These criticisms are unsurprising, since Rawls's arguments, as arguments that the principle of equal basic liberty needs to include democratic liberties, are incomplete. In contrast to (...) his trenchant remarks about core civil liberties, Rawls does not say much about the inclusion of political liberties of a democratic sort – such as the right to vote – among the basic liberties. -/- In this paper, I complete some of Rawls's arguments and show that he has grounds for including political liberties, particularly those of a democratic nature, in the principle of equal basic liberty. In doing so, I make some beginning steps toward illustrating the genuinely democratic nature of Rawls's arguments. Rawls believes that a few different arguments can be given for democratic institutions and that these arguments work together to support the value of democracy. In this paper, I focus on Rawls's arguments relating to self-respect. I focus on this set of arguments because they are among the strongest of Rawls's arguments for equal political liberty and its fair value. (shrink)

Judgment subjectivism is the view that x is good for S if and only if, because, and to the extent that S believes, under the proper conditions, that x is good for S. In this paper, I offer three related arguments against the theory. The arguments are about what judgment subjectivism implies about the well-being of welfare nihilists, people who believe there are no welfare properties, or at least that none are instantiated. I maintain that welfare nihilists can (...) be benefited and harmed. Judgment subjectivism is implausible because it implies otherwise. (shrink)

Climate change has become one of the most pressing problems that can threaten the existence and development of humans around the globe. Almost all climate scientists have agreed that climate change is happening and is caused mainly by greenhouse gas emissions induced by anthropogenic activities. However, some groups still deny this fact or do not believe that climate change results from human activities. This article examines climate change denialism and its skeptical arguments, as well as the roles of scientists (...) and science communication in addressing the issues. Through this article, we call for the active participation of scientists in science communication activities with the public, the initiation of new science communication sectors specified for climate change, and more attention to social sciences and humanities in addressing climate change issues.

I argue that, at least on the assumption that if there are epistemic facts they are irreducible, the evolutionary debunking maneuver is prima facie self-debunking because it seems to debunk a certain class of facts, namely, epistemic facts that prima facie it needs to rely on in order to launch its debunking arguments. I then appeal to two recent reconstructions of the evolutionary debunking maneuver (Kahane (2011), Griffiths and Wilkins (2015)) and find them wanting. Along the way I set (...) aside two ways (one envisaged, the other by Sterpetti (2015)) to avoid the self-debunking problem that I find unpromising. I conclude that the evolutionary debunking maneuver needs to clarify the meta-epistemological commitments upon which it is supposed to operate. (shrink)

Evolutionary debunking arguments purport to show that robust moral realism, the metaethical view that there are non-natural and mind-independent moral properties and facts that we can know about, is incompatible with evolutionary explanations of morality. One of the most prominent evolutionary debunking arguments is advanced by Sharon Street, who argues that if moral realism were true, then objective moral knowledge is unlikely because realist moral properties are evolutionary irrelevant and moral beliefs about those properties would not be selected (...) for. However, no evolutionary, causal explanation plays an essential role in reaching the argument’s epistemological conclusion. Street’s argument depends on the Benacerraf-Field challenge, which is the challenge to explain the reliability of our moral beliefs about causally inert moral properties. The Benacerraf-Field challenge relies on metaphysically necessary facts about realist moral properties, rather than on contingent Darwinian facts about the origin of our moral beliefs. Attempting to include an essential causal empirical premise yet avoiding recourse to the Benacerraf-Field problem yields an argument that is either self-defeating or of limited scope. Ultimately, evolutionary, causal explanations of our moral beliefs and their consequences do not present the strongest case against robust moral realism. Rather, the question is whether knowledge of casually-inert, mind-intendent properties is plausible at all. (shrink)

Modal collapse arguments are all the rage in certain philosophical circles as of late. The arguments purport to show that classical theism entails the absurdly fatalistic conclusion that everything exists necessarily. My first aim in this paper is bold: to put an end to action-based modal collapse arguments against classical theism. To accomplish this, I first articulate the ‘Simple Modal Collapse Argument’ and then characterize and defend Tomaszewski’s criticism thereof. Second, I critically examine Mullins’ new modal collapse (...) argument formulated in response to the aforementioned criticism. I argue that Mullins’ new argument does not succeed. Third, I critically examine a powers-based modal collapse argument against classical theism that has received much less attention in the literature. Fourth, I show why God’s being purely actual, as well God’s being identical to each of God’s acts, simply cannot entail modal collapse given indeterministic causation. This, I take it, signals the death of modal collapse arguments. But not all hope is lost for proponents of modal collapse arguments—for the death is a fruitful one insofar as it paves the way for new inquiry into at least two new potential problems for classical theism. Showing this is my paper’s second aim. (shrink)

David Miller argues that national identity is indispensable for the successful functioning of a liberal democracy. National identity makes important contributions to liberal democratic institutions, including creating incentives for the fulfilment of civic duties, facilitating deliberative democracy, and consolidating representative democracy. Thus, a shared identity is indispensable for liberal democracy and grounds a good claim for self-determination. Because Miller’s arguments appeal to the instrumental values of a national culture, I call his argument ‘instrumental value’ arguments. In this paper, (...) I examine the instrumental value arguments and show that they fail to justify a group’s right to self-determination. (shrink)

I will first discuss a peculiarity of the realism-antirealism debate. Some authors defending antirealist positions in a philosophical discussion seem to be inconsistent with what they do when treating scientific subjects. In the latter situation, they behave as realists. This tension can be dissolved by distinguishing different discourses belonging to different levels of philosophical radicality. Depending on the respective level, certain presuppositions are either granted or questioned. I will then turn to a discussion of the miracle argument by discussing a (...) simple example of curve fitting. In the example, multiple use-novel predictions are possible without indicating the truth of the fitting curve. Because this situation has similarities with real scientific cases, it sheds serious doubt upon the miracle argument. Next, I discuss the strategy of selective realism, especially its additional crucial component, the continuity argument. The continuity of some X in a series of theories, with X being responsible for the theories’ use-novel predictions, is taken to be a reliable indicator for the reality of X. However, the continuity of X could as well be due to the similarity of the theories in the series with an empirically very successful theory embodying X, without X being real. Thus, the two main arguments for scientific realism show severe weaknesses. (shrink)

Few have discussed Rawls's arguments for the value of democracy. This is because his arguments, as arguments that the principle of equal basic liberty should include democratic liberties, are incomplete. Rawls says little about the inclusion of political liberties of a democratic sort – such as the right to vote – among the basic liberties. And, at times, what he does say is unconvincing. My aim is to complete and, where they fail, to reconceive Rawls's arguments (...) and to show that a principle requiring equal political liberty and its fair value is an appropriate component of his theory of justice.

Part 5 distinguishes an infinite regress argument from (...) an infinite regress and defines an infinite regress. Part 6 explains the dyslogistic force of 'infinite regress'. (shrink)

Which of the two dominant arguments for duties to alleviate global poverty, supposing their premises were generally accepted, would be more likely to produce their desired outcome? I take Pogge's argument for obligations grounded in principles of justice, a "contribution" argument, and Campbell's argument for obligations grounded in principles of humanity, an "assistance" argument, to be prototypical. Were people to accept the premises of Campbell's argument, how likely would they be to support governmental reform in policies for international aid, (...) or to make individual contributions to international aid organizations? And I ask the same question, mutatis mutandis, for Pogge's argument. (shrink)

I criticize some armchair arguments against phenomenal externalism due to Block, Hawthorne, Kriegel, Levine, Shoemaker and others. I conclude by discussing an overlooked armchair argument: the argument from phenomenal localism.

Several authors have recently argued against intellectualism, the view that one’s epistemic position with respect to p depends exclusively on one’s truth-relevant factors with respect to p. In this paper, I first examine two prominent arguments for the anti-intellectualist position and find both of them wanting. More precisely, I argue that these arguments, by themselves, are underdetermined between intellectualism and anti-intellectualism. I then manifest the intuitive plausibility of intellectualism by examining the ordinary conversational pattern of challenging a claim.

Arguments are nowadays often presented as soundbites: as slogans, tweets, memes and even gifs. Arguments developed in detail often meet the response TL;DR (Too Long, Didn’t Read). This is unfortunate—especially when tackling the topic of abortion. Soundbites make many pro-life arguments seem stronger than they really are, while the complexities of pro-choice arguments can’t be readily reduced to soundbites.

In sections 2.21.23-25 of An Essay concerning Human Understanding, John Locke considers and rejects two ways in which we might be “free to will”, which correspond to the Thomistic distinction between freedom of exercise and freedom of specification. In this paper, I examine Locke’s arguments in detail. In the first part, I argue for a non-developmental reading of Locke’s argument against freedom of exercise. Locke’s view throughout all five editions of the Essay is that we do not possess freedom (...) of exercise (at least in most cases). In the second part, I argue that, when Locke asks whether we possess freedom of specification, his question is intentionally ambiguous between two readings, a first-order reading and a higher-order reading. Locke’s view is that, on either reading, we do not possess freedom of specification (at least in any interesting sense). (shrink)

This chapter discusses epistemic objections to non-naturalist moral realism. The goal of the chapter is to determine which objections are pressing and which objections can safely be dismissed. The chapter examines five families of objections: (i) one involving necessary conditions on knowledge, (ii) one involving the idea that the causal history of our moral beliefs reflects the significant impact of irrelevant influences, (iii) one relying on the idea that moral truths do not play a role in explaining our moral beliefs, (...) (iv) one involving the claim that if moral realism is true then our moral beliefs are unlikely to be reliable, and (v) one involving the claim that moral realism is incompatible with there being a plausible explanation of our reliability about morality. The overall conclusion of the chapter is that the final objection is by far the most pressing. (shrink)

This paper explores and defends a form of transcendental argument that is neither bold in its attempt to answer the sceptic, as ambitious transcendental strategies, nor epistemically humble, as modest transcendental strategies. While ambitious transcendental strategies seek to meet the sceptical challenge, and modest transcendental strategies accept the validity of the challenge but retreat to a position of epistemic humility, this form of transcendental argument denies the assumption that undergirds the challenge, namely that truth and falsity may be legitimately predicated (...) of the conditions of knowledge. As a result, although this form of transcendental argument is not truth-directed, it is not vulnerable to a charge that is often levelled against modest transcendental arguments, namely that they amount to the adoption of a strategy of sophisticated capitulation. This form of transcendental argument, which is implicit in Collingwood’s conception of philosophy as the search for absolut... (shrink)

May assumes that if moral beliefs are counterfactually dependent on irrelevant factors, then those moral beliefs are based on defective belief-forming processes. This assumption is false. Whether influence by irrelevant factors is debunking depends on the mechanisms through which this influence occurs. This raises the empirical bar for debunkers and helps May avoid an objection to his Debunker’s Dilemma.

The theory-ladenness of perception argument is not an argument at all. It is two clusters of arguments. The first cluster is empirical. These arguments typically begin with a discussion of one or more of the following psychological phenomena: (a) the conceptual penetrability of the visual system, (b) voluntary perceptual reversal of ambiguous figures, (c) adaptation to distorting lenses, or (d) expectation effects. From this evidence, proponents of theory-ladenness typically conclude that perception is in some sense "laden" with theory. (...) The second cluster attempts to extract deep epistemological lessons from this putative fact. Some philosophers conclude that science is not (in any traditional sense) a rational activity, while others conclude that we must radically reconceptualize what scientific rationality involves. Once we understand the structure of these arguments, much conventional wisdom about the significance of the psychological data turns out to be false. (shrink)

Rather than set out an overarching view or take a stand on the debunking of morality tout court, in what follows I’ll explore a divide and conquer strategy. First, I will briefly sketch a debunking argument that, instead of targeting all of morality or human moral nature, has a more narrow focus—namely, the intuitive moral authority of disgust. The argument concludes that as vivid and compelling as they can be while one is in their grip, feelings of disgust should be (...) granted no power to justify moral judgments. Importantly, the argument is grounded in empirical advances concerning the character of the emotion itself. Next, I will step back and consider the argument’s general form. I then point to arguments that others have made that seem to share this form and selective focus, and comment on what such arguments do and do not presuppose. Finally, I locate the selective strategy with respect to other approaches moral debunking. (shrink)

Arguments from human dignity feature prominently in the Lethal Autonomous Weapons moral feasibility debate, even though their exists considerable controversy over their role and soundness and the notion of dignity remains under-defined. Drawing on the work of Dieter Birnbacher, I fix the sub-discourse as referring to the essential value of human persons in general, and to postulated moral rights of combatants not covered within the existing paradigm of the International Humanitarian Law in particular. I then review and critique dignity-based (...) arguments against LAWS: argument from faulty targeting process, argument from objectification, argument from underappreciation of the value of human life and the argument from the absence of mercy. I conclude that the argument from the absence of mercy is the only dignity-based argument that is both valid and irreducible to another class of arguments within the debate, and that it offers insufficient justification for a global ban on LAWS.

Ever since Darwin people have worried about the sceptical implications of evolution. If our minds are products of evolution like those of other animals, why suppose that the beliefs they produce are true, rather than merely useful? We consider this problem for beliefs in three different domains: religion, morality, and commonsense and scientific claims about matters of empirical fact. We identify replies to evolutionary scepticism that work in some domains but not in others. One reply is that evolution can be (...) expected to design systems that produce true beliefs in some domain. This reply works for commonsense beliefs and can be extended to scientific beliefs. But it does not work for moral or religious beliefs. An alternative reply which has been used defend moral beliefs is that their truth does not consist in their tracking some external state of affairs. Whether or not it is successful in the case of moral beliefs, this reply is less plausible for religious beliefs. So religious beliefs emerge as particularly vulnerable to evolutionary debunking.

Moral debunking arguments are meant to show that, by realist lights, moral beliefs are not explained by moral facts, which in turn is meant to show that they lack some significant counterfactual connection to the moral facts (e.g., safety, sensitivity, reliability). The dominant, “minimalist” response to the arguments—sometimes defended under the heading of “third-factors” or “pre-established harmonies”—involves affirming that moral beliefs enjoy the relevant counterfactual connection while granting that these beliefs are not explained by the moral facts. We (...) show that the minimalist gambit rests on a controversial thesis about epistemic priority: that explanatory concessions derive their epistemic import from what they reveal about counterfactual connections. We then challenge this epistemic priority thesis, which undermines the minimalist response to debunking arguments (in ethics and elsewhere). (shrink)

In “Milvian Bridges in Science, Religion, and Theology: Debunking Arguments and Cultural Evolution,” Lari Launonen and Aku Visala engage with an EDA against religious belief that appeals to cultural rather than biological evolution. According to this EDA, religious beliefs are unjustified, not because they are generated by biologically shaped cognitive processes that are unreliable as far as those beliefs are concerned but because they are generated by cultural processes that select for those beliefs for their ability to produce prosocial (...) behavior rather than for their truth sensitivity. Scientific beliefs, by contrast, are truth-sensitive because their cultural fitness depends on their power to produce accurate predictions. Their truth sensitivity explains the great amount of convergence on them that exists across cultures. In response to the EDA in question, Launonen and Visala argue that the difference between science and religion is actually more a matter of degree than a matter of kind, that there is considerable cross-cultural convergence on theistic and Christian beliefs, and that folk Christian beliefs, just as folk scientific ones, are truth-sensitive to the extent that they are constrained by expert beliefs.

While philosophers have worried about mental causation for centuries, worries about the causal relevance of conscious phenomena are also increasingly featuring in neuroscientific literature. Neuroscientists have regarded the threat of epiphenomenalism as interesting primarily because they have supposed that it entails free will scepticism. However, the steps that get us from a premise about the causal irrelevance of conscious phenomena to a conclusion about free will are not entirely clear. In fact, if we examine popular philosophical accounts of free will, (...) we find, for the most part, nothing to suggest that free will is inconsistent with the presence of unconscious neural precursors to choices. It is only if we adopt highly non-naturalistic assumptions about the mind (e.g. if we embrace Cartesian dualism and locate free choice in the non-physical realm) that it seems plausible to suppose that the neuroscientific data generates a threat to free will.

This paper defends the case against (sparse) disjunctive properties by means of four Armstrongian arguments. The first of these is a logical atomist argument from truthmaking, which is, broadly speaking, ‘Armstrongian’ (Armstrong 1997). This argument is strong – although it stands or falls with the relevant notion of truthmaking, as it were. However, three arguments, which are prima facie independent of truthmaking, can be found explicitly early in Armstrong’s middle period. Two of these early arguments face a (...) serious objection put forward forcefully by Louise Antony (2003) and Alan Penczek (1997), respectively. I consider these objections and argue that they fail. Thus, even if the argument from truthmaking is indecisive, disjunctive properties should be rejected. (shrink)

In this paper, I offer reasons for thinking that two prominent sceptical arguments in the literature – the underdetermination-based sceptical argument and the closure-based sceptical argument – are less philosophically interesting than is commonly supposed. The underdetermination-based argument begs the question against a non-sceptic and can be dismissed with little fanfare. The closure-based argument, though perhaps not question-begging per se, does rest upon contentious assumptions that a non-sceptic is under no pressure to accept.

In this paper we discuss the new Tweety puzzle. The original Tweety puzzle was addressed by approaches in non-monotonic logic, which aim to adequately represent the Tweety case, namely that Tweety is a penguin and, thus, an exceptional bird, which cannot fly, although in general birds can fly. The new Tweety puzzle is intended as a challenge for probabilistic theories of epistemic states. In the first part of the paper we argue against monistic Bayesians, who assume that epistemic states can (...) at any given time be adequately described by a single subjective probability function. We show that monistic Bayesians cannot provide an adequate solution to the new Tweety puzzle, because this requires one to refer to a frequency-based probability function. We conclude that monistic Bayesianism cannot be a fully adequate theory of epistemic states. In the second part we describe an empirical study, which provides support for the thesis that monistic Bayesianism is also inadequate as a descriptive theory of cognitive states. In the final part of the paper we criticize Bayesian approaches in cognitive science, insofar as their monistic tendency cannot adequately address the new Tweety puzzle. We, further, argue against monistic Bayesianism in cognitive science by means of a case study. In this case study we show that Oaksford and Chater’s (2007, 2008) model of conditional inference—contrary to the authors’ theoretical position—has to refer also to a frequency-based probability function.

Various theorists contend that we may live in a computer simulation. David Chalmers in turn argues that the simulation hypothesis is a metaphysical hypothesis about the nature of our reality, rather than a sceptical scenario. We use recent work on consciousness to motivate new doubts about both sets of arguments. First, we argue that if either panpsychism or panqualityism is true, then the only way to live in a simulation may be as brains-in-vats, in which case it is unlikely (...) that we live in a simulation. We then argue that if panpsychism or panqualityism is true, then viable simulation hypotheses are substantially sceptical scenarios. We conclude that the nature of consciousness has wide-ranging implications for simulation arguments. (shrink)

Significant attention as been devoted to the problem of ‘divine hiddenness’ proposed by JL Shellenberg. I propose a novel response that involves denying part of the empirical premise in divine hiddenness arguments, which holds that nonresistant nonbelievers are capable of relationship with God. While Plantinga and others in ‘reformed’ epistemology have at times appealed to original sin as an explanation for divine hiddenness, such responses might seem outlandish to many, given the way that many find nonbelievers to be no (...) more or less epistemically or morally blameworthy than believers. Further, such appeals to original sin seem to give a ‘just-so’ story that at least leaves the situation dialectically balanced. I show that a classically Augustinian notion of original sin can provide a sufficient response to those objections, and that appeal to original sin can form an empirically grounded response to the divine hiddenness problem, beyond a simple defense. If the possibility of original sin-type scenarios is compatible with God’s perfect love, then the phenomenon of apparently nonresistant nonbelievers would push us toward considering the possibility that humans have lost those capacities for relationship with God by a Fall-like event in the past.

Debunking arguments in ethics contend that our moral beliefs have dubious evolutionary, cultural, or psychological origins—hence concluding that we should doubt such beliefs. Debates about debunking are often couched in coarse-grained terms—about whether our moral beliefs are justified or not, for instance. In this paper, I propose a more detailed Bayesian analysis of debunking arguments, which proceeds in the fine-grained framework of rational confidence. Such analysis promises several payoffs: it highlights how debunking arguments don’t affect all agents, (...) but rather only those agents who updated on their intuitions using a specific range of evidentiary weights; it underscores how the debunkers shouldn’t conclude that we should reduce confidence beyond some threshold, but rather only that we should reduce confidence by some amount; and it proposes a method of integrating different kinds of evidence—about the kinds of epistemic flaws at play, about the different possible origins of our moral beliefs, about the background normative assumptions we’re entitled to make—in order to arrive at a rational moral credence in light of debunking.

This paper explicates the influential Confucian view that “people” and not “institutional rules” are the proper sources of good governance and social order, as well as some notable Confucian objections to this position. It takes Xunzi 荀子, Hu Hong 胡宏, and Zhu Xi 朱熹 as the primary representatives of the “virtue-centered” position, which holds that people’s good character and not institutional rules bear primary credit for successful governance. And it takes Huang Zongxi 黃宗羲 as a major advocate for the “institutionalist” (...) position, which holds that institutional rules have some power to effect success independently of improvements in character. Historians have often called attention to this debate but left the major arguments and positions relatively unspecified. As I show, the Confucian virtue-centered view is best captured in two theses: first, that reforming people is far more demanding than reforming institutional rules; second, that once the rules have reached a certain threshold of viability, further improvements in those rules are unlikely to be effective on their own. Once we specify the theses in this way, we can catalogue the different respects and degrees to which the more virtue-centered political thinkers endorse virtue-centrism in governance. Zhu Xi, for example, turns out to endorse a stronger version of virtue-centrism than Hu Hong. I also use this account of the major theses to show that Huang Zongxi, who is sometimes regarded as historical Confucianism’s foremost institutionalist, has more complicated and mixed views about the power of institutional reform than scholars usually assume.

Reber and Alcock have recently made a sharp attack on the entire psi literature, and in particular a recent overview by Cardeña of the meta-analyses across various categories of psi. They claim the data are inherently fl awed because of their disconnect with our current understanding of the world. As a result, they ignore the data and identify key scientific principles that they argue clash with psi. In this Commentary, I argue that these key principles are diffi cult to apply (...) in areas where our understanding remains poor, especially quantum mechanics and consciousness. I also explore how the psi data may fi t within these two domains. (shrink)

John Maynard Keynes’s A Treatise on Probability is the seminal text for the logical interpretation of probability. According to his analysis, probabilities are evidential relations between a hypothesis and some evidence, just like the relations of deductive logic. While some philosophers had suggested similar ideas prior to Keynes, it was not until his Treatise that the logical interpretation of probability was advocated in a clear, systematic and rigorous way. I trace Keynes’s influence in the philosophy of probability through a heterogeneous (...) sample of thinkers who adopted his interpretation. This sample consists of Frederick C. Benenson, Roy Harrod, Donald C. Williams, Henry E. Kyburg and David Stove. The ideas of Keynes prove to be adaptable to their diverse theories of probability. My discussion indicates both the robustness of Keynes’s probability theory and the importance of its influence on the philosophers whom I describe. I also discuss the Problem of the Priors. I argue that none of those I discuss have obviously improved on Keynes’s theory with respect to this issue. (shrink)

metempsychosis is the concept of the transmigration of a human or animal soul into another human, animal, plant, or even an inanimate object. The theory of metempsychosis poses a challenge to the belief in resurrection (maʿād), making it necessary to reject metempsychosis before proving maʿād. Avicenna presents two arguments against metempsychosis. The first argument, found in numerous works, rejects metempsychosis on the grounds that it requires the union of two soul s within a single body. Avicenna alludes to the (...) second argument in his Al-Isharat wa al-Tanbihat but postpones its full explanation to another unspecified work. Nasir al-Din al-Tusi, Fakhr al-Din Razi, and Qutb al-Din Razi have proposed different interpretations of this second argument. The variations in interpretation revolve around the number of implications Avicenna expressed for this modus ponendo and his reasons for rejecting them. Among these interpretations, only Qutb al-Din Razi's aligns more closely with Avicenna's original words. In the other two interpretations, there are either deficiencies or excesses compared to Avicenna's work. (shrink)

Relational egalitarianism holds that people should live together as equals. We argue against the received wisdom amongst both friends and foes of relational egalitarianism that it fails to provide a theory of intergenerational justice. Instead, we argue that relational egalitarianism is concerned with social equality amongst future contemporaries, and that this commitment gives rise to duties of justice for current generations that can be grounded in the idea of generational overlap. In doing so, we argue that that the scope of (...) relational egalitarian concerns extends beyond generations amongst whom social relations exist. (shrink)

In defending the view that justice is the advantage of the stronger, Thrasymachus puzzlingly claims that rulers never err and that any practitioner of a skill or expertise (τέχνη) is infallible. In what follows, Socrates offers a number of arguments directed against Thrasymachus’ views concerning the nature of skill, ruling, and justice. Commentators typically take a dim view of both Thrasymachus’ claims about skill (which are dismissed as an ungrounded and purely ad hoc response to Socrates’ initial criticisms) and (...) Socrates’ latter arguments (which are deemed extremely weak). In this paper, I clarify Thrasymachus’ views (and those of several other ancients) concerning qua locutions and the nature of skill and ability and I reconstruct Socrates’ arguments against Thrasymachus’ views concerning skill and justice. I argue that Thrasymachus’ views are not ungrounded or ad hoc and that Socrates’ arguments are rather different (and significantly stronger) than often supposed. (shrink)

This paper appeals to the phenomenon of dreaming to provide a novel defense against arguments from evil. The thrust of the argument is as follows: when we wake up after a nightmare we are often filled entirely with relief, and do not consider ourselves to have actually suffered very much at all; and since it is epistemically possible that this whole life is simply a dream, it follows that it is epistemically possible that in reality there is very little (...) suffering. This epistemic possibility decisively undermines a key premise of both logical and evidential arguments from evil. (shrink)

Axel Gosseries considers, and partly defends, several strategies to address the non-identity problem (NIP). We engage critically with two strategies endorsed by Gosseries: the severance strategy and the overlap strategy. The latter comprises two different sub-strategies: the containment sub-strategy and the indirect sub-strategy. We believe that severance is less promising than Gosseries suggests. It comes at a high theoretical cost, which is important to acknowledge even if, ultimately, there is reason to pay it. The sub-strategies that comprise the overlap strategy (...) are more promising, and they can justify more in terms of the scope and content of inter-generational justice than Gosseries suggests in his book. Endorsing the overlap strategies is attractive because doing so limits the need for impersonal considerations in theories of inter-generational justice. (shrink)

Agent relativists about vagueness (henceforth ‘agent relativists’) hold that whether or not an object x falls in the extension of a vague predicate ‘P’ at a time t depends on the judgemental dispositions of a particular competent agent at t. My aim in this paper is to critically examine arguments that purport to support agent relativism by appealing to data from forced-march Sorites experiments. The most simple and direct versions of such forced-march Sorites arguments rest on the following (...) (implicit) premise: If competent speakers' judgements vary in a certain way, then the extensions of ‘P’ as used by these speakers must vary in the same way. This premise is in need of independent support, since otherwise opponents of agent relativism can simply reject it. In this paper, I focus on the idea that one cannot plausibly reject this premise, as that would commit one to implausible claims about linguistic competence. Against this, I argue that one can accommodate the data from forced-march Sorites experiments in a way that is compatible with a plausible picture of linguistic competence, without going agent relativist. Thus, there is reason to be sceptical of the idea that such data paired with considerations about linguistic competence can be invoked in order to lend any solid support to agent relativism. Forced-march Sorites arguments of this kind can, and should be, resisted. (shrink)

Taking people’s longevity as a measure of good life, humankind can proudly say that the average person is living a much longer life than ever before. The AIDS epidemic has however for the first time in decades stalled and in some cases even reverted this trend in a number of countries. Climate change is increasingly becoming a major challenge for food security and we can anticipate that hunger caused by crop damages will become much more common. -/- Since many of (...) the challenges humanity faced in the past were overcome by inventive solutions coming from the life sciences, we are compelled to reconsider how we incentivize science and technology development so that those in need can benefit more broadly from scientific research. There is a huge portion of the world population that is in urgent need for medicines to combat diseases that are currently neglected by the scientific community and could immensely benefit from agricultural research that specifically targets their environmental conditions. At the same time efforts have to be made to make the fruits of current and future research more widely accessible. These changes would have to be backed by a range of moral arguments to attract people with diverging notions of global justice. This article explores the main ethical theories used to demand a greater share in the benefits from scientific progress for the poor. Since life sciences bring about a number of special concerns, a short list of conflictive issues is also offered. (shrink)

The re-use of publicly available (personal) data for originally unanticipated purposes has become common practice. Without such secondary uses, the development of many AI systems like large language models (LLMs) and ChatGPT would not even have been possible. This chapter addresses the ethical implications of such secondary processing, with a particular focus on data protection and privacy issues. Legal and ethical evaluations of secondary processing of publicly available personal data diverge considerably both among scholars and the general public. While some (...) of these uses are met with opposition and criticism, others are quite unanimously viewed as unproblematic. Often, proponents and opponents of such practices invoke the same ethical and legal standards for their opposite conclusions. This state of affairs shows that other considerations besides the public availability of data must play a role. It calls for a theoretical clarification of the additional criteria that should guide decisions about the (legally informed) ethical acceptability of re-processing practices. In order to make a contribution towards this goal, the present chapter maps the ongoing debate and systematises the existing contributions around three lines of argument: a consent-centred position, an approach that focuses on the distinction between data and information, and finally a line of argument that focuses on the contextual norms that govern the flows of information. The chapter further relates these arguments to three underlying conceptions of privacy and data protection: rights-based, structural and contextual, and discusses the advantages and disadvantages of each position in the light of concrete examples. It concludes by arguing for a mixed approach that combines core elements of the structural and contextual approaches. The chapter aims to contribute to existing research in the fields of data, AI and research ethics, and to reconnect the debate with ethical and legal scholarship on privacy and data protection. In doing so, it aims to make a theoretical contribution towards refining existing conceptions of privacy and data protection in order to make them more fit to ‘drive our digital world’ as far as the use of publicly available data is concerned.
