In adversarial machine learning, attackers add carefully crafted perturbations to input, where the perturbations are almost imperceptible to humans, but can cause models to make wrong predictions. In this paper, we did comprehensive review of some of the most recent research, advancement and discoveries on adversarial attack, adversarial sampling generation, the potency or effectiveness of each of the existing attack methods, we also did comprehensive review on some of the most recent research, advancement and discoveries on (...) class='Hi'>adversarial defense strategies, the effectiveness of each defense methods, and finally we did comparison on effectiveness and potency of different adversarial attack and defense methods. We came to conclusion that adversarial attack will mainly be blackbox for the foreseeable future since attacker has limited or no knowledge of gradient use for NN model, we also concluded that as dataset becomes more complex, so will be increase in demand for scalable adversarial defense strategy to mitigate or combat attack, and we strongly recommended that any neural network model with or without defense strategy should regularly be revisited, with the source code continuously updated at regular interval to check for any vulnerability against newer attack.

In this research, we focus on the usage of adversarial sampling to test for the fairness in the prediction of deep neural network model across different classes of image in a given dataset. While several framework had been proposed to ensure robustness of machine learning model against adversarial attack, some of which includes adversarial training algorithm. There is still the pitfall that adversarial training algorithm tends to cause disparity in accuracy and robustness among different group. Our (...) research is aimed at using adversarial sampling to test for fairness in the prediction of deep neural network model across different classes or categories of image in a given dataset. We successfully demonstrated a new method of ensuring fairness across various group of input in deep neural network classifier. We trained our neural network model on the original image, and without training our model on the perturbed or attacked image. When we feed the adversarial samplings to our model, it was able to predict the original category/ class of the image the adversarial sample belongs to. We also introduced and used the separation of concern concept from software engineering whereby there is an additional standalone filter layer that filters perturbed image by heavily removing the noise or attack before automatically passing it to the network for classification, we were able to have accuracy of 93.3%. Cifar-10 dataset have ten categories of dataset, and so, in order to account for fairness, we applied our hypothesis across each categories of dataset and were able to get a consistent result and accuracy.

Shirking, the act of avoiding the demands of one’s job, is generally seen as unethical. Drawing on empirical evidence from the sociology of work, I develop a normative conception of shirking as a form of worker resistance against illegitimate managerial power. In doing so, I present a new approach to the political theory of the firm, which is more adversarial and agent-centered than available alternatives. It is more adversarial as it recognizes the political value of counterproductive and disruptive (...) behavior in capitalist firms. It is more agent-centered because it theorizes the firm from the perspective of workers, asking what pro tanto reasons they have to shirk. I show that shirking under the structural domination of capitalism has diagnostic, agential, and epistemic values. The paper contributes to the wider methodological ambition to tailor political theorizing to the positionality of social actors by shifting attention from the institutional design of the firm to the methods of worker resistance.

After a fatal police shooting in the United States, it is typical for city and police officials to view the family of the deceased through the lens of the law. If the family files a lawsuit, the city and police department consider it their legal right to defend themselves and to treat the plaintiffs as adversaries. However, reparations and the concept of “reparative justice” allow authorities to frame police killings in moral rather than legal terms. When a police officer kills (...) a person who was not liable to this outcome, officials should offer monetary reparations, an apology, and other redress measures to the victim’s family. To make this argument, the article presents a philosophical account of non-liability hailing from self-defense theory, centering the distinction between reasonableness and liability. Reparations provide a non-adversarial alternative to civil litigation after a non-liable person has been killed by a police officer. In cases where the officer nevertheless acted reasonably, “institutional agent-regret” rather than moral responsibility grounds the argument for reparations. Throughout the article, it is argued that there are distinct racial wrongs both when police kill a non-liable black person and when family members of a black victim are treated poorly by officials in the civil litigation process.

It is trivially true that comedians make jokes and thus are not serious; they are “just playing.” But watching Louis CK, especially his performances in Chewed Up, Shameless, and Hilarious, it is evident that he has more in mind than simply getting his audience to frivolously guffaw. I will make the case that this is so given the content of some of his humor which centers on areas of socio-political-ethical tensions that can be uncomfortable when addressed in a direct, “bona-fide” (...) communicative mode. I will concentrate upon his playful, yet serious, account of issues surrounding race and privilege which, though not obvious center-pieces, can be found in almost all of his performances. These are complex areas that are not obvious fodder for humor, and it is clear that his comedic repertoire is broad enough that he is not including these issues for lack of funnier bits. I will argue that through his humor, he at once brings to consciousness hidden biases, challenges them in a subversive manner on behalf of those harmed by cultural stereotypes, e.g., and opens up an otherwise adversarial audience to the possibility that they harbor such unwanted stereotypes—a necessary element in consciousness-raising. My account will require a brief distinction between seriousness and playfulness, a defense of the claim that we are drawn to humor even when it is used to question our cherished presuppositions, and an interpretation of thought experiments that parallels Louis CK’s comedic mechanisms in his stand-up performances and episodes from Louie. In some cases he is explicit that he is just “making shit up” (Oh My God), or, as he cautions in the setup to a story in Shameless, “it doesn’t matter cus’ I’m gonna lie to you.” But that does not take away from my point that he is serious with his humor about social reality in the same way that philosophers have traditionally “made shit up” with thought experiments for serious purposes. Louis CK employs a similar device with his humor, and in many ways is more effective than philosophers in making the implicit explicit for his (much larger) audiences who then spread his word.

"Transparency" is the constant refrain of democratic politics, a promised aid to accountability and integrity in public life. Secrecy is stigmatized as a work of corruption, tolerable by a compromise of democratic principles. My dissertation challenges both ideas. It argues that secrecy and transparency are best understood as complementary, not contradictory, practices. And it develops a normative account of liberal democratic politics in which duties of transparency coexist with permissions to act behind closed doors. The project begins with some history. (...) I show that the language of transparency gained currency only in the last quarter century, and explain how its proximate sources promote three dubious assumptions—that disclosure should in principle be maximized, that it prevents misrule more or less automatically, and that its value is either instrumental, or rooted in a reductive notion of democracy as the rule of popular opinion. Against these assumptions, I sketch an alternative account of liberal democracy centered on the logics of representation, liberty, and equality. These three "logics of self-government" give rise to duties of transparency binding on public and private actors alike. Such obligations have bite, I argue, but they are not all-encompassing. Indeed, the same ideals of representation, liberty, and equality license concealment in a range of important contexts, including deliberation and dissent. Having made this case, I go on to explain how secrecy and transparency can form a "democratic dyad," deepening rather than undermining the project of self-rule. Lastly, I address the limits of conventional transparency practices. Taken alone, disclosure is subject to a range of pitfalls, often failing to produce the results promised in transparency’s name. While my non-instrumental case for openness is not destabilized by this analysis, it does suggest that mandating disclosure is rarely enough. I therefore propose a series of adversarial practices to facilitate the checking of unjustifiable secrecy, and highlight the critical role of interpretation in efforts to make power intelligible. In the end, my dissertation offers a novel defense of secrecy and transparency that highlights rather than minimizes the hard work of political engagement. (shrink)

Wars are large-scale conflicts between organized groups of belligerents, which involve suffering, devastation, and brutality unlike almost anything else in human experience. Whatever one’s other beliefs about morality, all should agree that the horrors of war are all but unconscionable, and that warfare can be justified only if we have some compel- ling account of what is worth fighting for, which can justify contributing, as individu- als and as groups, to this calamitous endeavour. Although this question should obviously be central (...) to both philosophical and politi- cal discussion about war, it is at the forefront of neither. In recent years, philosophical discussion of warfare has bloomed, but the debate has focused on whom we may kill, on the assumption that our aims are justified.1 Political debate, meanwhile, is more concerned with matters of prudence, international law, and public justification, than with reassessing what is worth fighting for. For wars of intervention to halt or prevent massive humanitarian crises, this gap is not so troubling. When warfare is the only means to prevent the mass killing or enslavement of the innocent, the purposes of military force are clear enough (though undoubtedly many other problems remain). The problem is more pressing, how- ever, for the justification of national defence.3 Although common-sense morality and international law view national defence as the paradigm case of justified warfare, grounding this consensus is surprisingly difficult.4 We typically believe that any state is justified in using lethal force to protect its territory against any form of uninvited military incursion by any other state. And yet we lack a good argument to explain why this should be so. In this chapter, I explain why one familiar and otherwise plausible approach to the justification of killing in war cannot adequately ground common-sense views of permissible national defence.5 Reductionists believe that justified warfare reduces to an aggregation of acts that are justified under ordinary principles of interpersonal morality.6 The standard form of reductionism focuses on the principles governing killing in ordinary life, specifically those that justify intentional killing in self- and other-defence, and unintended but foreseen (for short, collateral) killing as a lesser evil. Justified warfare, on this view, is no more than the coextension of multiple acts justified under these two principles. Reductionism is the default philosophical approach to thinking through the ethics of killing in war. It makes perfect sense to ask what principles govern permissible kill- ing in general, before applying them to the particular context of war. If it cannot deliver a plausible set of conclusions about when national defence is permitted, then we must either revise our beliefs about which conclusions count as plausible, or else face the significant challenge of developing a different theoretical model for justifying war- fare—an exceptionalist model, which views war as an exception to the regular moral landscape, to which principles apply which apply to nothing else but war.7 We must show, in other words, that there is something worth fighting for in wars of national defence, which is not engaged when we use force in any other context. The chapter proceeds as follows. Section 2.2 sets out the argument against reduc- tionism.8 Section 2.3 considers and rebuts one common response to the argument, which has often been thought sufficient grounds to disregard its conclusion. Section 2.4 then asks whether a modified reductionism would survive unscathed by the argu- ment. Finally, section 2.5 sets out some desiderata on a plausible exceptionalist alterna- tive. Section 2.6 concludes. (shrink)

As a painfully outdated institution the school is accused of: being alienating, closing itself off to society and to the needs of young people; reproducing social inequality and consolidating existing power relations; demotivating youth; showing a lack of effectiveness and having great difficulty with employability. And last but not least, the school is considered redundant: the school, where learning is bound to time and place, is no longer needed in the digital era of virtual learning environments. The ultimate charge: the (...) school is a product of outdated ways of distributing knowledge and expertise, determined by primitive technologies of the past. Adieu school. This book advocates the acquittal of the school. It argues that many of the allegations against the school are motivated by an age-old fear and even hatred toward one of its radical but essential characteristics: that the school provides ‘free time' and transforms knowledge and skills into 'common goods', and therefore has the potential to give everyone, regardless of background, natural talent or aptitude, the time and space to leave their known environment, rise above themselves and renew (and thus change in unpredictable ways) the world. This defence of the school starts from an investigation of what makes a school a school and pinpoints why the school has value in and of itself. It reveals the various attempts to rob the school of its scholastic character, that is, to tame the school. The ultimate aim is to elaborate a touchstone that helps to defend as well as to re-invent school. -/- Jan Masschelein and Maarten Simons are members of the Laboratory for Education and Society, KU Leuven. They share an interest in research on the public dimensions of education and are currently elaborating a philosophy of schooling. (shrink)

Recent years have seen growing interest in modifying interventionist accounts of causal explanation in order to characterise noncausal explanation. However, one surprising element of such accounts is that they have typically jettisoned the core feature of interventionism: interventions. Indeed, the prevailing opinion within the philosophy of science literature suggests that interventions exclusively demarcate causal relationships. This position is so prevalent that, until now, no one has even thought to name it. We call it “intervention puritanism” (I-puritanism, for short). In this (...) paper, we mount the first sustained defence of the idea that there are distinctively noncausal explanations which can be characterized in terms of possible interventions; a position we call “intervention liberalism” (I-liberalism, for short). While many have followed James Woodward (2003) in committing to I-puritanism, we trace support for I-liberalism back to the work of Jaegwon Kim (1974). Furthermore, we analyse two recent sources of scepticism regarding I-liberalism: debate surrounding mechanistic constitution; and attempts to provide a monistic account of explanation. We show that neither literature provides compelling reasons for adopting I-puritanism. Finally, we present a novel taxonomy of available positions upon the role of possible interventions in explanation: weak causal imperialism; strong causal imperialism; monist intervention puritanism; pluralist intervention puritanism; monist intervention liberalism; and finally, the specific position defended in this paper, pluralist intervention liberalism.

This article offers an account and defence of constructionism, both as a metaphilosophical approach and as a philosophical methodology, with references to the so-called maker's knowledge tradition. Its main thesis is that Plato's “user's knowledge” tradition should be complemented, if not replaced, by a constructionist approach to philosophical problems in general and to knowledge in particular. Epistemic agents know something when they are able to build (reproduce, simulate, model, construct, etc.) that something and plug the obtained information into the correct (...) network of relations that account for it. Their epistemic expertise increases with the scope and depth of the questions that they are able to ask and answer. Thus, constructionism deprioritises mimetic, passive, and declarative knowledge that something is the case, in favour of poietic, interactive, and practical knowledge of something being the case. Metaphilosophically, constructionism suggests adding conceptual engineering to conceptual analysis as a fundamental method. (shrink)

I consider some of the objections that have been raised against a conceptualist solution to the “grounding problem”, I address in particular two objections that I call Conceptual Validity and Instantiation, and I attempt to answer them on behalf of the conceptualist. My response, in a nutshell, is that the first of these objections fails because it ascribes to the conceptualist some commitments that do not really follow from the view’s basic insight, while the second objection also fails because it (...) denies the conceptualist resources that the alternative positions are allowed to use.

Although few linguists currently embrace the empirical paradigm, there are increasing calls for the development of tools for studying language that resemble those in exact sciences. This trend can be observed even in top mainstream linguistic journals, such as the Journal of Pragmatics, as exemplified by Xiang (2017). Today, however, linguists who adapt the methodologies from more advanced sciences face isolation from the mainstream linguistic community. This is because the majority of linguists in philological and philosophical departments remain convinced that (...) the object of their studies is fundamentally different from those studied by physicists. Therefore, they argue that linguistic methodology cannot resemble that used in empirical sciences. As a result, linguistics is often seen as requiring interpretation rather than an explanation, and evaluation of linguistic research is based on acceptance within the scholarly community rather than empirical testing.

In this paper I propose a novel defence of political cosmopolitanism grounded in a familiar principle: universal moral equality. Critics of cosmopolitanism generally agree to universal moral equality, but disagree about what moral equality means politically. According to my argument, if we accept that all people are morally equal, then we ought to accept their equal moral standing. We should therefore prefer socio-political arrangements that reflect the equal moral standing of all people over those that reflect differentiated moral standing. A (...) reasonable cosmopolitanism need not preclude partialist attachment to co-nationals, or undermine the significance of self-determination, so long as political arrangements do not produce differentiated moral standing. As the political application of an uncontroversial moral principle, I defend reasonable cosmopolitanism against nationalism and statism. Neither of these, I argue, are suitable foundations for global justice in migration because they each conceive of justice as a local concern for insiders. (shrink)

In this paper, we attempt to show that if Plantinga’s free will defence succeeds, his O Felix Culpa theodicy fails. For if every creaturely essence suffers from transworld depravity, then given that Jesus has a creaturely essence (as we attempt to show), it follows that Incarnation and Atonement worlds cannot be actualized by God, in which case we have anything but a felix culpa.

Cartesians and Lichtenbergians have diverging views of the deliverances of introspection. According to the Cartesians, a rational subject, competent with the relevant concepts, can come to know that he or she thinks – hence, that he or she exists – on the sole basis of his or her introspective awareness of his or her conscious thinking. According to the Lichtenbergians, this is not possible. This paper offers a defence of the Lichtenbergian position using Peacocke and Campbell's recent exchange on Descartes'scogitoas (...) a framework for discussion. A thought-experiment will be presented involving two communities with radically different conceptions of the metaphysics of the self. The purpose of the thought-experiment is to suggest that a substantive metaphysical thesis, whose truth cannot be a priori known, is presupposed by any justified transition from one's introspective awareness of a certain mental activity to the self-ascription of that activity.

The availability of the defence of belief in consent under section 265(4) is a question of law, subject to review on appeal. The statutory provision is based on the common law rule that applies to all defences. Consideration of the defence when it is unavailable in law and failure to consider it when it is available are both incorrect. A judge is most likely to avoid error when ruling on availability of the defence if the ruling: (1) is grounded on (...) sound analysis of the substantive basis for the defence and its relationship to the principles of criminal responsibility; and (2) uses precise legal criteria to govern practical application of section 265(4) to the evidence in specific cases. The guidelines proposed in Part I are based on analyses of the substantive defence and culpable awareness and were developed to ensure that appropriate criteria are properly used when section 265(4) is applied. When a trial judge rules that the defence is available in law, the trier of fact must determine whether the defence is available on the facts as found, based on the evidence in the case. The model jury instructions proposed in Part II are designed to ensure that deliberations by the trier of fact are also guided and shaped by appropriate legal criteria. At both stages, the objective is to ground the deliberation process on fact, not fiction, and to regulate the exculpatory effect of the defence by using legal norms to exclude excuses based on extra-legal considerations such as sexual/racial fantasy, stereotype and myth, or community attitudes and custom.

This is the revised version of an invited keynote lecture delivered at the "1st Australian Computing and Philosophy Conference". The paper is divided into two parts. The first part defends an informational approach to structural realism. It does so in three steps. First, it is shown that, within the debate about structural realism, epistemic and ontic structural realism are reconcilable. It follows that a version of OSR is defensible from a structuralist-friendly position. Second, it is argued that a version of (...) OSR is also plausible, because not all relata are logically prior to relations. Third, it is shown that a version of OSR is also applicable to both sub-observable and observable entities, by developing its ontology of structural objects in terms of informational objects. The outcome is informational structural realism, a version of OSR supporting the ontological commitment to a view of the world as the totality of informational objects dynamically interacting with each other. The paper has been discussed by several colleagues and, in the second half, ten objections that have been moved to the proposal are answered in order to clarify it further. (shrink)

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)

This article argues that access to meaningful sexual experience should be included within the set of the goods that are subject to principles of distributive justice. It argues that some people are currently unjustly excluded from meaningful sexual experience and it is not implausible to suggest that they might thereby have certain claim rights to sexual inclusion. This does not entail that anyone has a right to sex with another person, but it does entail that duties may be imposed on (...) society to foster greater sexual inclusion. This is a controversial thesis and this article addresses this controversy by engaging with four major objections to it: the misogyny objection; the impossibility objection; the stigmatisation objection; and the unjust social engineering objection.

The idea that humans should abandon their individuality and use technology to bind themselves together into hivemind societies seems both farfetched and frightening – something that is redolent of the worst dystopias from science fiction. In this article, we argue that these common reactions to the ideal of a hivemind society are mistaken. The idea that humans could form hiveminds is sufficiently plausible for its axiological consequences to be taken seriously. Furthermore, far from being a dystopian nightmare, the hivemind society (...) could be desirable and could enable a form of sentient flourishing. Consequently, we should not be so quick to deny it. We provide two arguments in support of this claim – the axiological openness argument and the desirability argument – and then defend it against three major objections. (shrink)

I suggest that the theories of remembering one finds in the philosophy of memory literature are best characterised as theories principally operating at three different levels of inquiry. Simulationist views are theories of the psychofunctional process type remembering. Causalist views are theories of referential remembering. Epistemic views are theories of successful remembering. Insofar as there is conflict between these theories, it is a conflict of integration rather than—as widely presented—head‐on disagreement. Viewed in this way, we can see the previous awareness (...) condition and preservationism as principles applying at only some of the corresponding levels of inquiry. Where either principle has been rejected, it is, I claim, due to arguments which slip between these different levels. While the view of the landscape I offer does not dissolve ongoing disputes about the nature of remembering, it clarifies the dialectical rules of engagement, helping to clear the path for future, collaborative progress to be made. The view enables us to see less conflict in the recent philosophy of memory literature than there seems at face value to be. (shrink)

Hybrid contingentism combines first-order contingentism, the view that it is contingent what individuals there are, with higher-order necessitism, the view that it is non-contingent what properties and propositions there are (where these are conceived as entities in the range of appropriate higher-order quantifiers). This combination of views avoids the most delicate problems afflicting alternative contingentist positions while preserving the central contingentist claim that ordinary, concrete entities exist contingently. Despite these attractive features, hybrid contingentism is usually faced with rejection. The main (...) reason for this is an objection that crucially involves haecceitistic properties, properties such as being identical to Plato or being identical to Aristotle. The objection alleges that by accepting the necessary existence of such haecceities, hybrid contingentists incur an explanatory commitment that they are unable to discharge, namely that of explaining how it is that certain haecceities ‘lock onto’ their target individuals even when those individuals are absent. To defend hybrid contingentism against this charge, I first clarify the haecceities objection in several respects and consider, in particular, what notion of explanation the objection is operating with. After arguing that it can be fruitfully understood as a challenge to provide metaphysical grounds for certain haecceity facts, I develop a contingentist response to the objection that draws on recent work on the connection between ground and essence.

When I say that my conception of metaphysics is Aristotelian, or neo-Aristotelian, this may have more to do with Aristotle’s philosophical methodology than his metaphysics, but, as I see it, the core of this Aristotelian conception of metaphysics is the idea that metaphysics is the first philosophy . In what follows I will attempt to clarify what this conception of metaphysics amounts to in the context of some recent discussion on the methodology of metaphysics (e.g. Chalmers et al . (2009), (...) Ladyman and Ross (2007)). There is a lot of hostility towards the Aristotelian conception of metaphysics in this literature: for instance, the majority of the contributors to the Metametaphysics volume assume a rather more deflationary, Quinean approach towards metaphysics. In the process of replying to the criticisms towards Aristotelian metaphysics put forward in recent literature I will also identify some methodological points which deserve more attention and ought to be addressed in future research.

The Swamping Problem shows that two claims are incompatible: the claim that knowledge has more epistemic value than mere true belief and a strict variant of the claim that all epistemic value is truth or instrumental on truth. Most current solutions reject. Carter and Jarvis and Carter, Jarvis and Rubin object instead to a principle that underlies the problem. This paper argues that their objections fail and the problem stands. It also outlines a novel solution which rejects. By carefully distinguishing (...) value from expected value, one can argue that the greater value of knowledge is merely apparent. (shrink)

I confront Feyerabend's position and critical rationalism in order to have a foundation or starting point for my (historical) investigation. The main difference of his position towards falsificationism is the belief that different theories cannot be discussed rationally. Feyerabend is convinced that Galilei's observations with the telescope in the historical context of the Copernican revolution supports his criticism. In particular, he argues that the Copernican theory was supported by deficient hypotheses, and falsifications were disposed by ad hoc hypotheses and propaganda. (...) Furthermore, he claims that his philosophy of science reconstructs Galilei's defence of the Copernican theory. He introduces a central principle of his position (the principle of tenacity) in order to justify a research strategy of not eliminating falsified theories. He tries to show that the tenacious defence of a theory corresponds to Galilei's defence of the Copernican theory. Remarkably, Feyerabend's approach to explain the development of science earns an important support from his interpretation of Galilei's observations. On this basis I give a falsificationist interpretation of Galilei's observations with the telescope, and oppose this interpretation to Feyerabend's. From a falsificationist perspective, auxiliary hypotheses compete during the Copernican revolution which can (with some effort) be critically discussed. Then I analyse the historical case in order to test Feyerabend's interpretation of the Copernican revolution. Inter alias I investigate thoroughly whether Galilei, as Feyerabend claims, immunised falsifications of the Copernican theory by the introduction of ad hoc hypotheses. The investigation considers Galilei's explanation of Venus' phases, his establishment of the irradiation hypothesis, the explanation of the telescope's functionality, and the role of the reproducibility of the observations with the telescope. Finally I provide a rational reconstruction of Galilei's falsification of the Ptolemaic theory. The formalisation shows that Galilei was not a cautious critical rationalist, but a very confident scientist using the method of falsification. (shrink)

I defend a weak version of the Pigou-Dalton principle for chances. The principle says that it is better to increase the survival chance of a person who is more likely to die rather than a person who is less likely to die, assuming that the two people do not differ in any other morally relevant respect. The principle justifies plausible moral judgements that standard ex post views, such as prioritarianism and rank-dependent egalitarianism, cannot accommodate. However, the principle can be justified (...) by the same reasoning that has recently been used to defend the core axiom of ex post prioritarianism and egalitarianism, namely, Pigou-Dalton for well-being. The arguably biggest challenge for proponents of Pigou-Dalton for chances is that it violates State Dominance for social prospects. However, I argue that we have independent reason for rejecting State Dominance for social prospects, since it prevents a social planner from properly respecting people's preferences. (shrink)

The austere view of nonsense says that the source of nonsense is not a violation of the rules of logical syntax, but nonsense is always due to a lack of meaning in one of the components of a sentence. In other words, the necessary and sufficient condition for nonsensicality is that no meaning has been assigned to a constituent in a sentence. The austere conception is the key ingredient of the resolute reading of Tractatus Logico-Philosophicus that presents a therapeutical interpretation (...) of the work, and rejects a possibility of conveying some ineffable truths by means of nonsensical sentences. In this paper, I defend the austere view against the most important objections. Firstly, I discuss textual sources for ascribing to Wittgenstein the austere view that have not been sufficiently thoroughly discussed yet. Next, I indicate that the apparent occurrence of words out of the context of a sentence on lists of verbs and in definitions is not in conflict with the version of the context principle recommended by austere theorists, since this argument does not sufficiently take into account the distinction between sign and symbol. Furthermore, I argue that the austere conception and the principle of compositionality are jointly tenable, for the former view does not exclude the existence of syntactic and semantic rules, but only shows that they are recognizable conditionally. Finally, I indicate that the austere view of nonsense should be seen as a viable option by a contemporary theorist of nonsense, for it helps us to avoid making controversial assumptions about the nature of meaning and content.

One popular defence of moral omnivorism appeals to facts about the indirectness of the diner’s causal relationship to the suffering of farmed animals. Another appeals to the claim that farmed animals would not exist but for our farming practices. The import of these claims, I argue, has been misunderstood, and the standard arguments grounded in them fail. In this paper, I develop a better argument in defence of eating meat which combines resources from both of these strategies, together with principles (...) of population ethics, and discuss its implications for which sorts of meat it is permissible to eat. According to the diner’s defence, there is an asymmetry between producers and consumers of meat. Producers can prevent the suffering of animals without preventing their existence, but consumers cannot. This asymmetry grounds a defence against harm-based objections to eating meat which is available to the consumer alone, and which avoids the controversial commitments about moral status or the interests of nonhuman animals endemic to existing attempts to justify omnivorism.

According to philosophical orthodoxy, there are informative criteria of identity over time. Anti-criterialism rejects this orthodoxy and claims that there are no such criteria. This paper examines anti-criterialism in the light of recent attacks on the thesis by Matt Duncan, Sydney Shoemaker and Dean Zimmerman. It is argued that those attacks are not successful. Along the way, a novel strategy to defend anti-criterialism against the critics’ most challenging objection is developed. Under-appreciated difficulties for criterialism are also raised which, I claim, (...) there is no obvious way to solve. It is concluded that anti-criterialism may be a much stronger rival to criterialism than is often supposed. (shrink)

Can a person be harmed or wronged by being brought into existence? Can a person be benefited by being brought into existence? Following David Heyd, I refer to these questions as “genethical questions”. This chapter examines three broad approaches to genethics: the no-faults model, the dual-benchmark model, and the parity model. The no-faults model holds that coming into existence is not properly subject to moral evaluation, at least so far as the interests of the person that is to be brought (...) into existence are concerned. The dual benchmark model allows that coming into existence can be subject to moral evaluation, but holds that our judgments about the kinds of lives worth starting ought not be aligned with our judgments about the kinds of lives worth sustaining. I argue against both the no-faults and dual benchmark models. In their place, I argue for a parity approach to genethics, according to which our judgments about the conditions under which life is worth creating ought to be constrained by our judgments about the conditions under which life is worth continuing.

Many contemporary philosophers rate error theories poorly. We identify the arguments these philosophers invoke, and expose their deficiencies. We thereby show that the prospects for error theory have been systematically underestimated. By undermining general arguments against all error theories, we leave it open whether any more particular arguments against particular error theories are more successful. The merits of error theories need to be settled on a case-by-case basis: there is no good general argument against error theories.

Recent work in the philosophy of religion has resurrected Leibniz’s idea that there is a best possible world, perhaps ours. In particular, Klaas Kraay’s [2010] construction of a theistic multiverse and Nevin Climenhaga’s [2018] argument from infinite value theory are novel defenses of a best possible world. I do not think that there is a best world, and show how both Kraay and Climenhaga may be resisted. First, I argue that Kraay’s construction of a theistic multiverse can be resisted from (...) plausible assumptions about set theory. Next, I argue against the value-theoretic assumptions that underlie Climenhaga’s argument and show how to give an infinite value theory where there is no best world. (shrink)

'Mindfulness' is arguably the most important concept to have transplanted from Buddhist thought to contemporary Western psychology. However, whilst mindfulness was already an ambiguous term in the original context, specified more by a set of practices than by a clear definition, its cross-cultural transmission has blurred its content even further. In this paper, I assess the recent criticism of the widespread definition of mindfulness as non-elaborative, purely receptive 'bare attention'. According to the critics of bare attention, what can be characterized (...) as purely receptive is the automatic turning of attention toward an object. But should mindfulness be a quality of consciousness that is to be established and developed by the reflexive practice of meditation, it must be something more than this automatic turning of attention. This paper shows how the definition of mindfulness as bare attention can be defended by explicating it in terms of the phenomenological model of attention. (shrink)

This paper offers a defence of metaphysical naturalism, in the context of the Fine Tuning argument. Theistic objections to the Multiverse (MV) hypothesis are considered, specifically the claim that the MV hypothesis commits the Inverse Gambler’s Fallacy (IGF) and, as per the This Universe Objection (TUO), that it violates the Requirement of Total Evidence. It is argued that the IGF claim moved the goalposts when it comes to assessing the validity of the MV hypothesis. The Cosmic Slot Machine analogy will (...) be used to demonstrate how the This Universe Objection (TUO), fails to adequately account for the anthropic principle (or selection effect) and how the MV hyptothesis does satisfy the Requirement for Total Evidence. -/- With respect to the Naturalistic Single Universe (NSU), the implications of the ex-nihilonihil- fit principle, for evaluating the epistemic probability of a Life Permitting Universe (LPU)under the NSU hypothesis, are considered. It is argued that the ex nihilo nihil fit principle entails that an LPU is not improbable under the NSU hypothesis. (shrink)

Many including Judith Jarvis Thomson, Philippa Foot, Peter Geach, Richard Kraut, and Paul Ziff have argued for good simpliciter skepticism. According to good simpliciter skepticism, we should hold that there is no concept of being good simpliciter or that there is no property of being good simpliciter. I first show that prima facie we should not accept either form of good simpliciter skepticism. I then show that all of the arguments that good simpliciter skeptics have proposed for their view fail (...) to show that we have good reason to accept good simpliciter skepticism. So, I show that we do not have good reason to accept good simpliciter skepticism. (shrink)

According to Jim Pryor’s dogmatism, when you have an experience with content p, you often have prima facie justification for believing p that doesn’t rest on your independent justification for believing any proposition. Although dogmatism has an intuitive appeal and seems to have an antisceptical bite, it has been targeted by various objections. This paper principally aims to answer the objections by Roger White according to which dogmatism is inconsistent with the Bayesian account of how evidence affects our rational credences. (...) If this were true, the rational acceptability of dogmatism would be seriously questionable. I respond that these objections don’t get off the ground because they assume that our experiences and our introspective beliefs that we have experiences have the same evidential force, whereas the dogmatist is uncommitted to this assumption. I also consider the question whether dogmatism has an antisceptical bite. I suggest that the answer turns on whether or not the Bayesian can determine the priors of hypotheses and conjectures on the grounds of their extra-empirical virtues. If the Bayesian can do so, the thesis that dogmatism has an antisceptical bite is probably false. (shrink)

Here I reply to the main points raised by the commentators on the arguments put forward in my Delusions and Other Irrational Beliefs (OUP, 2009). My response is aimed at defending a modest doxastic account of clinical delusions, and is articulated in three sections. First, I consider the view that delusions are inbetween perceptual and doxastic states, defended by Jacob Hohwy and Vivek Rajan, and the view that delusions are failed attempts at believing or not-quitebeliefs, proposed by Eric Schwitzgebel and (...) Maura Tumulty. Then, I address the relationship between the doxastic account of delusions and the role, nature, and prospects of folk psychology, which is discussed by Dominic Murphy, Keith Frankish, and Maura Tumulty in their contributions. In the final remarks, I turn to the continuity thesis and suggest that, although there are important differences between clinical delusions and non-pathological beliefs, these differences cannot be characterised satisfactorily in epistemic terms.

Pereboom’s Four-Case Argument was once considered to be the most powerful of the manipulation arguments against compatibilism. However, because of Demetriou’s :595–617, 2010) response, Pereboom has significantly weakened his argument. Manipulation arguments in general have also been challenged by King : 65–83, 2013). In this paper, I argue that the Four-Case Argument resists both these challenges. One upshot is that Pereboom doesn’t need weaken his argument. Another is that compatibilists still need a response the Four-Case Argument. And another is that (...) we get a much better understanding of the Four-Case Argument, and of manipulation arguments more generally, than is currently available in the literature. (shrink)

The distinction between dimensions and units in physics is commonplace. But are dimensions a feature of reality? The most widely-held view is that they are no more than a tool for keeping track of the values of quantities under a change of units. This anti-realist position is supported by an argument from underdetermination: one can assign dimensions to quantities in many different ways, all of which are empirically equivalent. In contrast, I defend a form of dimensional realism, on which some (...) assignments of dimensions to quantities better describe reality than others. The argument I provide is a form of inference to the best explanation. In particular, the technique of dimensional analysis is explanatory, but it is only successful for certain systems of dimensions. Since these dimensional systems support scientific explanations, we have reason to believe that they are real. (shrink)

Intentionalism about demonstratives is the view that the referent of a demonstrative is determined solely by the speaker's intentions. Intentionalists can disagree about the nature of these intentions, but are united in rejecting the relevance of other factors, such as the speaker's gestures, her gaze, and any facts about the addressee or the audience. In this paper, I formulate a particular version of this view, and I defend it against six objections, old and new.

Business ethics is often understood as a variety of professional ethics, and thus distinct from ordinary morality in an important way. This article seeks to challenge two ways of defending this claim: first, from the nature of business practice, and second, from the contribution of business. The former argument fails because it undermines our ability to rule out a professional-ethics approach to a number of disreputable practices. The latter argument fails because the contribution of business is extrinsic to business in (...) a way that distinguishes from the established professions. The article ultimately suggests we adopt a more aspirational approach to business ethics, which retains an appeal even in the face of charges of anti-capitalist irrelevance. (shrink)

In this paper, we defend Lucretian Presentism. Although the view faces many objections and has proven unpopular with presentists, we rehabilitate Lucretianism and argue that none of the objections stick.

This paper addresses criticisms of the concept of untranslatability which Davidson and Putnam have raised against the incommensurability thesis.

Do numbers exist? Do properties? Do possible worlds? Do fictional characters? Many metaphysicians spend time and effort trying to answer these and other questions about the existence of various entities. These inquiries have recently encountered opposition: a group of philosophers, drawing inspiration from Aristotle, have argued that many or all of the existence questions debated by metaphysicians can be answered trivially, and so are not worth debating. Our task is to defend existence questions from the neo-Aristotelians' attacks.

This paper considers issues raised by Elizabeth Anderson’s recent critique of the position she terms ‘luck egalitarianism’. It is maintained that luck egalitarianism, once clarified and elaborated in certain regards, remains the strongest egalitarian stance. Anderson’s arguments that luck egalitarians abandon both the negligent and prudent dependent caretakers fails to account for the moderate positions open to luck egalitarians and overemphasizes their commitment to unregulated market choices. The claim that luck egalitarianism insults citizens by redistributing on the grounds of paternalistic (...) beliefs, pity and envy, and by making intrusive and stigmatizing judgments of responsibility, fails accurately to characterize the luck egalitarian’s rationale for redistribution and relies upon luck egalitarians being insensitive to the danger of stigmatization. The luck egalitarian position is reinforced by the fact that Anderson’s favoured conception of equality, ‘democratic equality’, is counterintuitively indifferent to all unchosen inequalities, including intergenerational inequalities, once bare social minima are met.

A reply to Patrick Stokes' “Between Generalism and Particularism About Conspiracy Theory".

Divine command theories come in several different forms but at their core all of these theories claim that certain moral statuses exist in virtue of the fact that God has commanded them to exist. Several authors argue that this core version of the DCT is vulnerable to an epistemological objection. According to this objection, DCT is deficient because certain groups of moral agents lack epistemic access to God’s commands. But there is confusion as to the precise nature and significance of (...) this objection, and critiques of its key premises. In this article, I try to clear up this confusion and address these critiques. I do so in three ways. First, I offer a simplified general version of the objection. Second, I address the leading criticisms of the premises of this objection, focusing in particular on the role of moral risk/uncertainty in our understanding of God’s commands. And third, I outline four possible interpretations of the argument, each with a differing degree of significance for the proponent of the DCT. (shrink)
