In an article in Cognition, Machery, Mallon, Nichols, and Stich [Machery et al., 2004] present data which purports to show that “East Asian” native Cantonese speakers tend to have descriptivist intuitions about the referents of proper names, while “Western” native English speakers tend to have causal-historical intuitions about proper names. Machery et al take this finding to support the view that some intuitions, the universality of which they claim is central to philosophical theories, vary according to cultural background. Machery et (...) al hypothesize that the differences in intuitions about reference stem from general psychological differences between Eastern and Western subjects. Machery et al conclude from their findings that the philosophical methodology of consulting intuitions about hypothetical cases is flawed vis ` a vis the goal of determining truths about some philosophical domains. To quote Machery et al, “our data indicate that philosophers must radically revise their methodology” because “the intuitions philosophers pronounce from their armchairs are likely to be a product of their own culture and their academic training” ( [Machery et al., 2004] pp.B9). “The evidence suggests that it is wrong for philosophers to assume a priori the universality of their own semantic intuitions” ( [Machery et al., 2004] pp. B8). In the following study, I present data incompatible with Machery et al’s results. Native Cantonese-speaking immigrants from a Cantonese diaspora 1 in Southern California do not have descriptivist intuitions about the referents of proper names when presented with a Cantonese story and Cantonese questions about reference and truth-value. This data raises questions about the quality of Machery et al’s study and the conclusions they draw from it. (shrink)

This paper assesses the comparative reliability of two belief-revision rules relevant to the epistemology of disagreement, the Equal Weight and Stay the Course rules. I use two measures of reliability for probabilistic belief-revision rules, calibration and Brier Scoring, to give a precise account of epistemic peerhood and epistemic reliability. On the calibration measure of reliability, epistemic peerhood is easy to come by, and employing the Equal Weight rule generally renders you less reliable than Staying the Course. On the Brier-Score measure (...) of reliability, epistemic peerhood is much more difficult to come by, but employing the Equal Weight rule always renders you more reliable than Staying the Course. I conclude with some normative lessons we can draw from these formal results. (shrink)

This paper considers two questions. First, what is the scope of the Equal Weight View? Is it the case that meeting halfway is the uniquely rational method of belief-revision in all cases of known peer disagreement? The answer is no. It is sometimes rational to maintain your own opinion in the face of peer disagreement. But this leaves open the possibility that the Equal Weight View is indeed sometimes the uniquely rational method of belief revision. Precisely what is the skeptical (...) import of this fact; is it the case that some form of skepticism triumphs in such cases? The answer to this question is also no. As it turns out, the situations in which it is most plausible that the Equal Weight view is a rational requirement are the ones in which meeting halfway with a disagreeing peer brings you closer to, and not farther from, knowledge. I argue for these theses in a novel way; by looking at the comparative reliability of belief- invariance and meeting halfway using measures of reliability for degrees of belief, and by drawing normative conclusions from such results. The conclusions here can have the effect of reframing the entire debate in the epistemology of disagreement. (shrink)

This paper aims to discuss two realist conceptions about causation in the light of the general theory of relativity. I first consider the conserved quantity of causation, which explicitly relies on the energy conservation principle. Such principle is however problematic within GTR, mainly because of the dynamical nature of the spacetime structure itself. I then turn to the causal theory of properties, according to which properties are such that insofar as they are certain qualities, they are powers to produce certain (...) effects. In order to be compatible with GTR, such theory has to assume non-trivial global conditions on the spacetime structure; such assumptions seem to deprive the „singularist‟ non-Humean feature of this theory of causation. The question of the possible causal nature of spacetime properties is addressed in the conclusion. (shrink)

Classical theories of epistemic rationality take an agent\\textquoteright{}s individual beliefs to be the only things that are rational or irrational. For them, rationality is wholly static. Recent work in epistemology take sets of individual beliefs and also changes of belief over time to be rational or irrational. For these theories, rationality is both static and dynamic. However, for both groups, static rationality is fundamental. In my dissertation, I argue to the contrary that, in fact, all rationality is dynamic rationality. Epistemic (...) reasons, rationality, and justi{}cation as applying only to changes of belief. This wholly dynamic view of rationality, which I call \\textquotedblleft{}Dynamicism\\textquotedblright has wide-ranging epistemological consequences. A small set of simple, elegant, and independently motivated principles of dynamic rationality can illuminate and solve otherwise interminable epistemological disputes. (shrink)

On conduct of life and ethics of Islamic seminarians.

Nowadays, there is still a widely held view that the Chinese and Western modes of thought are quite distinct from each other. In particular, the Chinese mode of thought derived from Confucianism is considered as comparatively less rational than the Western one. In this article, I first argue that although the analogical mode of argumentation, which is often claimed to be in sharp contrast with the Western mode of rationalism, has played a prominent role in Confucianism, it does not make (...) Confucianism any less rational. Then, I examine the normative and communicative features of Confucian rationalism, exploring the implications of these features for critical thinking in education.

According to the Instrumental Conception of Epistemic Rationality believing rationally is believing in such a way so as to best satisfy one’s cognitive goals. I provide a novel argument against the Instrumental Conception on the basis of an unnoticed phenomenon I call “rational preemption.” You can now revise your plans and actions rationally in order to preempt or prevent foreseeable future irrationality. However, you cannot now revise your beliefs rationally in order to preempt or prevent foreseeable future irrationality. The ability (...) to be preemptively practically rational in your actions and plans, but not preemptively epistemically rational in your beliefs, implies that epistemic rationality is not a species of practical rationality, and thus, ICER is false.

Karl Popper’s falsificationist epistemology that all knowledge advances through a process of conjectures and refutations carries profound implications for politics and education. In this article, I first argue that, on a political level, it is necessary to establish and maintain an open society by fostering not only five core values, viz. freedom, tolerance, respect, rationalism, and equalitarianism, but also three crucial practices, viz. democracy, state interventionism, and piecemeal social engineering. Then, considering that an open society places great political, and thus (...) educational, demands upon its members, I examine the role played by education in its establishment and maintenance, focusing on its educational aims, curriculum, and pedagogy.

Bohm 's approach to quantum field theory is illustrated through its application to cavity quantum scalar field dynamics. Specific calculations demonstrate how the evolution of the well-defined scalar field is governed by the nature of its quantum state. The implications of the nonlocality inherent in quantum mechanics and the meaning of the classical limit are discussed in this context.

Appealing to imagination for modal justification is very common. But not everyone thinks that all imaginings provide modal justification. Recently, Gregory and Kung :620–663, 2010) have independently argued that, whereas imaginings with sensory imageries can justify modal beliefs, those without sensory imageries don’t because of such imaginings’ extreme liberty. In this essay, I defend the general modal epistemological relevance of imagining. I argue, first, that when the objections that target the liberal nature of non-sensory imaginings are adequately developed, those objections (...) also threaten the sensory imaginings. So, if we think that non-sensory imaginings are too liberal for modal justification, we should say the same about sensory imaginings. I’ll finish my defense by showing that, when it comes to deciding between saying that all imaginings are prima facie justificatory and saying that no imaginings are justificatory, there is an independent reason for accepting the former.

I offer some reasons for the theory that, compared with human beings, non-human animals have some but lesser intrinsic value. On the basis of this theory, I first argue that we do not know how to compare an animal's claim to be free from a more serious type of harm, and a human's claim to be free from some lesser type of harm. For we need to take account of these parties' intrinsic value, and their competing types of claim. Yet, (...) there exists no known way for making such comparison, when a human's intrinsic value is higher than that of an animal, whereas the type of claim an animal has is morally weightier than the type of claim a human has. Second, I explain why utilitarianism is unhelpful in making such comparison. Third, in the case where some animals can be sacrificed for saving a larger number of humans, it is crucial to ask whether animals have the right to life, and I argue that this question is more perplexing than we might think. My conclusion is that the various difficulties mentioned above have a deeper source than we have so far acknowledged, and that this reflects that the moral reality is less tidy and more complex than many theories portray.

In this essay, I aim to address the two related problems faced by ontological emergence and propose a solution. First, I shall briefly outline the concept of emergence, the distinction between ontological and epistemological emergence, as well as the distinction between synchronic and diachronic emergence, and focus mainly on synchronic ontological emergence. Second, I shall discuss the two related problems faced by synchronic ontological emergence—configurational forces and downward causation. Third, I shall present a solution to these problems—affirming ontological emergence but (...) denying vertical causation. Last, I shall address objections to the ontological emergence without vertical causation view. (shrink)

It’s intuitive to think that an intentional action requires that the agent knows that she’s doing so. In light of some apparent counterexamples, Setiya suggests that this intuitive insight is better captured in terms of credence: performing an intentional action requires the agent to have a higher credence that she’s doing so than she would have otherwise. I argue that there is no such thing as an agent’s credence for what she’s doing. After distinguishing this thesis from an idea some (...) defend under the slogan “deliberation crowds out prediction”, I explore the thesis’s broader epistemological implications for the belief-credence relation.

I argue that "quality of life" can be understood in three main ways: as purchasing power, together with social and political goods; as the subjective state of mind: happiness; happiness as related to the meaningfulness of one's profession or cause.

My aim in this paper is to argue against the claim that agent causation is more fundamental than event causation. To accomplish this aim, I shall first briefly discuss the motivation behind agent causation. Second, I shall highlight the differences between agent causation and event causation. Third, I shall begin briefly with the weaker claim held by Timothy O’Connor and Randolph Clarke that there is no good reason to believe that event causation is more fundamental than agent causation. Fourth, I (...) shall discuss the stronger claim held by E. J. Lowe that agent causation is more fundamental than event causation, and raise objections against the various arguments Lowe advances for the stronger claim. To the extent that my objections against Lowe’s stronger claim succeed, they raise questions for O’Connor’s and Clarke’s weaker claim. (shrink)

Tristram Engelhardt, Jr. offers erudite and compelling arguments for the view that all families should try to realize the traditional family. Although I tend to agree with him from my personal standpoint, I doubt that this view can be justified to those with whom we are in reasonable disagreement about the family. I make three critical points. First, though Engelhardt stops short of saying that the state should encourage people to form traditonal families, or discourage those who do not, some (...) state perfectionists might do so. From the perspective of public reason, it is unjust for the state to favor some conceptions of the good over others, if these conceptions are all reasonable. Moreover, those whose conceptions of the good are not favored would feel that they are disrespected. Second, insofar as Engelhardt thinks that all families should try to realize the traditional families, the traditional family would not be a good to those who do not like children. Moreover, it would be difficult to persuade those who have decided not to have children for reasons of career, burden, or more altruistic concern. Third, against Engelhardt’s stance against the “egalitarian aspirations” of liberalism, I argue that too often women sacrifice their possible careers for the sake of the family, even should they hold advanced degrees from prestigious universities, or professional qualifications. This kind of injustice is too uncomfortable to ignore. (shrink)

Reputation is a key component in social interactions of group-living animals and appears to play a role in the establishment of cooperation. Animals can form a reputation of an individual by directly interacting with them or by observing them interact with a third party, i.e., eavesdropping. Elephants are an interesting taxon in which to investigate eavesdropping as they are highly cooperative, large-brained, long-lived terrestrial mammals with a complex social organisation. The aim of this study was to investigate whether captive Asian (...) elephants could form reputations of humans through indirect and/or direct experience in two different paradigms: a cooperative string-pulling task and a scenario requiring begging. Fourteen captive Asian elephants in Thailand participated in an experimental procedure that consisted of three parts: baseline, observation, and testing. In the observation phase, the subject saw a conspecific interact with two people—one cooperative/generous and one non-cooperative/selfish. The observer could then choose which person to approach in the test phase. The elephants were tested in a second session 2–5 days later. We found no support for the hypothesis that elephants can form reputations of humans through indirect or direct experience, but these results may be due to challenges with experimental design rather than a lack of capacity. We discuss how the results may be due to a potential lack of ecological validity in this study and the difficulty of assessing motivation and attentiveness in elephants. Furthermore, we highlight the importance of designing future experiments that account for the elephants' use of multimodal sensory information in their decision-making. (shrink)

I argue that the personhood of a fetus is analogous to the the heap. If this is correct, then the moral status or intrinsic value of a fetus would be supervenient upon the fetus's biological development. Yet to compare its claim vis-a-vis its mother's, we need to consider not only their moral status, but also the type of claim they each have. Thus we have to give weight to the two factors or variables of the mother's moral status and her (...) claim to some lesser good . And then we have to consider the fetus's lesser moral status and its claim to some greater good, namely, life. I argue that we do not know how to compare these two-variable claims. This also explains why the central cases of abortion have been so difficult to resolve. I suggest that the problem of animal rights has a similar structure. (shrink)

ABSTRACT This paper attempts to read Nishida Kitarō (1870–1945) as a New Confucian, with a focus on his early moral philosophy. While the influence of Buddhism on Nishida’s philosophy is surely significant, this paper argues that it is actually Confucianism which plays a more important role. It is for this reason that fruitful comparisons can be made between his work and the so-called New Confucianism. I would like to explore three key questions with respects to this important yet relatively overlooked (...) aspect: Firstly, in what way has Nishida conformed to Confucian discourse in his moral philosophy? Secondly, what elements of Confucianism has Nishida revisited? Thirdly, what lessons can Nishida offer to philosophy as a New Confucian? It is my suggestion that reading Nishida as a New Confucian may help to further open up the potential of Nishida philosophy, Confucian philosophy, as well as philosophy in East Asia in general.

Lenman 's cluelessness objection against consequentialism states that we are almost entirely clueless to the actual consequences of our action. In ‘Cluelessness,’ Hilary Greaves distinguishes between ‘simple’ and ‘complex’ cases of cluelessness and argues that the principle of indifference applies to ‘simple’ cases, thereby rescuing the ‘simple’ cases from the cluelessness objection. In this discussion note, I argue that Greaves's distinction between ‘simple’ and ‘complex’ cases fails and cluelessness is more problematic than Greaves believes.

Lam, Joseph Peter Fitzsimons is a competent journalist who does not shy away from expressing his personal opinion on controversial social and ethical issues. In a Sydney Morning Herald online comment published on 11 December 2016, he not only praised the courage of the premier of Victoria, Daniel Andrews, but also appealed to members of the New South Wales parliament to follow Andrews' lead to legalise euthanasia. Anticipating the eventual collapse of his own health in the future, Fitzsimons insisted that (...) lawmakers should respect his autonomy and his choice of a peaceful and dignified death. As far as I can see, however, respect for a person's autonomy is not the main problem here. Rather, the key difficulty rests with Fitzsimons's reasoning. He argued: Let's say that at the age of 80 or so, I decide that my meaningful life is over, and all that awaits me is-I know, I know, too much detail- incontinent pain for the next five years. And let's say that I don't want that, and would rather pass away peacefully, and with dignity, in a medically supervised manner. My question to the opponents of euthanasia: if I choose to do that, what business is it of yours? (shrink)

Lam, Joseph In an audience for journalists shortly after his election in 2013 Pope Francis revealed not only the reason for his choice of name, but also his vision of the church: 'Francis of Assisi. For me he is the man of poverty, the man of peace, the man who loves and safeguards creation... He is the man who gives us this spirit of peace, the poor man... Oh, how I wish for a Church that is poor and for the (...) poor!' The Pontiff in his 2014 Lenten message re-emphasised the church's commitment to the poor. The responsibility of the church is 'to bear witness to all those who live in material, moral and spiritual destitution the Gospel message of the merciful love of God our Father, who is ready to embrace everyone in Christ. We can do this to the extent that we imitate Christ who became poor and enriched us by his poverty'. Pope Francis' concern for the poor is again reechoed in his latest encyclical, Laudato Si, in which he re-emphasises the church's commitment to the poor by calling Catholics especially to be stewards God's creation. A poor church for the poor, as Pope Francis envisages, has its foundation in the poverty of Jesus Christ: 'For you know the grace of our Lord Jesus Christ, that though he was rich, yet for your sake he became poor, so that by his poverty you might become rich'.

The global seafood industry is a vital source of food, income, livelihoods, and culture. Seafood demand is steadily rising due to growth in the global human population, affluence, and per capita consumption. Seafood supply is also growing, despite declining wild fish stocks, with phenomenal advances in aquaculture, that is, the cultivation of aquatic organisms. Aquaculture supplied 42 % of the world’s fish in 2012 and is forecast to eclipse capture fisheries production by 2030. The balance between these two seafood production (...) systems has profound implications for global food security, income distribution, and ecological sustainability. Here, a qualitative analysis of the ethics and sustainability of capture fisheries and aquaculture is presented. An innovative practical ethics approach is introduced which adapts the ethical matrix, a conceptual tool for analyzing the wellbeing, autonomy, and justice of different interest groups, and Rapfish, a rapid appraisal technique used to evaluate the sustainability of fisheries along six performance modalities, including ethics. Using case studies of global large- and small-scale capture fisheries and generalized carnivorous and omnivorous aquaculture systems, I show that human institutions and social actors interact in complex governance processes to influence seafood ethics and sustainability.

Some philosophers argue that non-presentist A-theories problematically imply that we cannot know that this moment is present. The problem is usually presented as arising from the combination of the A-theoretic ideology of a privileged presentness and a non-presentist ontology. The goal of this essay is to show that the epistemic problem can be rephrased as a pessimistic induction. By doing so, I will show that the epistemic problem, in fact, stems from the A-theoretic ideology alone. Hence, once it is properly (...) presented, the epistemic problem presents a serious threat to all A-theories. (shrink)

This book explores and elaborates three theories of public reason, drawn from Rawlsian political liberalism, natural law theory, and Confucianism. Drawing together academics from these separate approaches, the volume explores how the three theories critique each other, as well as how each one brings its theoretical arsenal to bear on the urgent contemporary debate of medical assistance in dying. The volume is structured in two parts: an exploration of the three traditions, followed by an in-depth overview of the conceptual and (...) historical background. In Part I, the three comprehensive opening chapters are supplemented by six dynamic chapters in dialogue with each other, each author responding to the other two traditions, and subsequently reflecting on the possible deficiencies of their own theories. The chapters in Part II cover a broad range of subjects, from an overview of the history of bioethics to the nature of autonomy and its status as a moral and political value. In its entirety, the volume provides a vibrant and exemplary collaborative resource to scholars interested in the role of public reason and its relevance in bioethical debate. (shrink)

In this paper, I present a critique of taxonomic pluralism, namely the view that there are multiple correct ways to classify entities into natural kinds within a given scientific domain. I argue that taxonomic pluralism, as an anti-essentialist position, fails to provide a realist alternative to taxonomic monism, i.e., the view that there is only one correct way to classify entities into natural kinds within a given scientific domain. To establish my argument, I first explain why the naturalist approach to (...) natural kinds adopted by pluralists requires them to give up the mind-independence criterion of reality presupposed by monists. Next, I survey two types of pluralist account. I argue that, while the modest pluralist account is not pluralistic enough, the radical pluralist account fails to come up with an alternative criterion of reality that is robust enough to differentiate its position from anti-realism about natural kinds. I conclude by drawing out the implications of my critique for the essentialism/anti-essentialism debate about natural kinds. (shrink)

Quantities like mass and temperature are properties that come in degrees. And those degrees (e.g. 5 kg) are properties that are called the magnitudes of the quantities. Some philosophers (e.g., Byrne 2003; Byrne & Hilbert 2003; Schroer 2010) talk about magnitudes of phenomenal qualities as if some of our phenomenal qualities are quantities. The goal of this essay is to explore the anti-physicalist implication of this apparently innocent way of conceptualizing phenomenal quantities. I will first argue for a metaphysical thesis (...) about the nature of magnitudes based on Yablo’s proportionality requirement of causation. Then, I will show that, if some phenomenal qualities are indeed quantities, there can be no demonstrative concepts about some of our phenomenal feelings. That presents a significant restriction on the way physicalists can account for the epistemic gap between the phenomenal and the physical. I’ll illustrate the restriction by showing how that rules out a popular physicalist response to the Knowledge Argument. (shrink)

Based on a rather simple thesis that we can learn from our mistakes, Karl Popper developed a falsificationist epistemology in which knowledge grows through falsifying, or criticizing, our theories. According to him, knowledge, especially scientific knowledge, progresses through conjectures that are controlled by criticism, or attempted refutations . As he puts it, ‘Criticism of our conjectures is of decisive importance: by bringing out our mistakes it makes us understand the difficulties of the problem which we are trying to solve. This (...) is how we become better acquainted with our problem, and able to propose more mature solutions: the very refutation of a theory ... is always a step forward that takes us nearer to the truth. And this is how we can learn from our mistakes’ . Since criticism plays such a crucial role in Popper's falsificationist methodology, it seems natural to envisage his heuristic as a helpful resource for developing critical thinking. However, there is much controversy in the psychological literature over the feasibility and utility of his falsificationism as a heuristic. In this paper, I first consider Popper's falsificationism within the framework of his critical rationalism, elucidating three core and interrelated concepts, viz. fallibilism, criticism, and verisimilitude. Then I argue that the implementation of Popper's falsificationism means exposing to criticism various philosophical presuppositions that work against criticism, such as essentialism, instrumentalism, and conventionalism; it also means combating what seems a common tendency of humans to be biased towards confirmation. I examine the confirmation bias, to which Popper did not give much attention: its pervasiveness and various guises, some theoretical explanations for it, and the role of teachers in undermining its strength and spread. Finally, I consider the question whether students can and should be taught to use disconfirmatory strategies for solving problems. (shrink)

According to Karl Popper’s critical rationalism, criticism is the only way we have of systematically detecting and learning from our mistakes so as to get nearer to the truth. Meanwhile, it is arguable that the emphasis of Confucianism on creating a hierarchical and harmonious society can easily lead to submission rather than opposition, producing a conformist rather than critical mind. A question arises here as to whether Confucianism tends to denigrate criticism and thus run counter to critical rationalism. In this (...) paper, I first argue that Confucianism prizes criticism and critical discussion, for which ample justification can be found in Confucian classics. Then I compare Confucianism with critical rationalism and assess the compatibility between them. (shrink)

The practice of giving the wealthy perpetual control of their assets is re-emerging in an era of great wealth inequality, long after it had been banned in common law countries. The philosophical justification for such control rests on the claim that there are posthumous rights to wealth, and that such rights do not extend in problematic way to other goods, such as political suffrage. On the basis of such a claim, we give people freedom of testation, and deem them vulnerable (...) to posthumous harm. I present a short history of legally sanctioned posthumous control of property in common law, and I argue that its philosophical justification is untenable. No principled case for posthumous rights to wealth survives scrutiny, and the large and powerful institutions that enforce such rights are morally illegitimate. (shrink)

Intuitively, the future is open and the past fixed: there is something we can do about the future but not the past. Some metaphysicians believe that a proper metaphysics of time must vindicate this intuition. Whereas philosophers have focused on the future and the past, the status of the present remains relatively unexplored. Drawing on resources from action theory, I argue that there is something we can do about the present just like there is something we can do about the (...) future. Hence, a proper metaphysics of the open future should allow for an open present as well. I argue that none of the major metaphysics of the open future currently available can accommodate an open present adequately. Finally, I’ll show that, surprisingly, the shrinking block metaphysics can. (shrink)

As he puts it, ‘Criticism of our conjectures is of decisive importance: by bringing out our mistakes it makes us understand the difficulties of the (...) problem which we are trying to solve. This is how we become better acquainted with our problem, and able to propose more mature solutions: the very refutation of a theory... is always a step forward that takes us nearer to the truth.

The belief that all human beings are ‘moral equals’ is widespread within the canon of Western liberal philosophy. However, it is unclear precisely what ‘moral equality’ or its associate terms mean, what grounds our ‘moral equality’ and what the implications of being ‘moral equals’ are. In this paper, I distinguish between three ways of understanding ‘moral equality’: the ‘buck-passing’, ‘explanatory’ and ‘reverse-explanatory’ accounts. The buck-passing account of moral equality is in parallel with Scanlon’s buck-passing account of value. It holds that (...) ‘moral equality’ is not a metaphysically fundamental concept and simply amounts to having other properties shared equally by all human beings that constitute the reasons for why we ought to treat all human beings equally in certain respects. The explanatory account understands the concept of ‘moral equality’ as metaphysically fundamental and explanatory of why human beings who are the same in certain respects have the same entitlement to x. The reverse-explanatory account also sees ‘moral equality’ as metaphysically fundamental but holds that the explanatory relationship goes the other way round: moral equality is explained by how we ought to act. I argue that the buck-passing account is a more accurate way of understanding moral equality. (shrink)

In “Two Dogmas”, Quine indicates that Carnap’s Aufbau fails “in principle” to reduce our knowledge of the external world to sense data. This is because in projecting the sensory material to reconstruct the physical world, Carnap gives up the use of operating rules and switches to a procedure informed by general principles. This procedure falls short of providing an eliminative translation for the connective “is at”, which is necessary for the reduction. In dissecting Quine’s objection, I argue that Quine has (...) at best proven the claim that the use of general principles essentially fails the task of radical reductionism. However, in order to establish the conclusion that the Aufbau fails in principle, Quine needs to further vindicate two other claims. They are: first, a switch from operating rules to general principles is necessary; second, the set of general principles Carnap adopts is the best alternative. By disambiguating the notion of “explicit definition” and examining the concept of definability in the Aufbau, I explore the possibility of justifying these two claims that Quine overlooks in his objection. The result suggests that Quine’s objection stands in tension with his radical reductionist reading of the Aufbau. (shrink)

As AI systems become increasingly complex it may become unclear, even to the designer of a system, why exactly a system does what it does. This leads to a lack of trust in AI systems. To solve this, the field of explainable AI has been working on ways to produce explanations of these systems’ behaviors. Many methods in explainable AI, such as LIME, offer only a statistical argument for the validity of their explanations. However, some methods instead study the internal (...) structure of the system and try to find components which can be assigned an interpretation. I believe that these methods provide more valuable explanations than those statistical in nature. I will try to identify which explanations can be considered internal to the system using the Chomskyan notion of tacit knowledge. I argue that each explanation expresses a rule, and through the localization of this rule in the system internals, we can take a system to have tacit knowledge of the rule. I conclude that the only methods which are able to sufficiently establish this tacit knowledge are those along the lines of Olah : 4901–4911, 2017), and therefore they provide explanations with unique strengths.

This paper examines whether physician-assisted suicide is morally permissible, and whether it should be legalised in the sense that those seeking or performing such procedure will be immune from prosecution. The issues of moral and legal permissibility1 are closely connected. One way to argue for the permissibility of PAS is grounded in the argument that a patient has the right to refuse life-saving equipment, or to have it withdrawn,2 and then to further argue that there is no relevant distinction between (...) refusal/withdrawal and PAS, if the patient consents. This is essentially the argument raised in “The Philosophers’ Brief ”, filed by six distinguished philosophers. However, this argument has been soundly criticised. Frances Kamm points out that the general claim on which Dworkin et al. rely—that there is no moral difference per se between killing and letting die—is false. This is because a patient has the right to refuse treatment even when this is against his interest because the alternative would be forced treatment, but it is not true to say that a patient has the right to PAS even when it is against his interest. Also at issue is the Doctrine of Double Effect, according to which there is a moral distinction between an action that is intended to cause death and one that is merely foreseen to cause death. [End Page 224] In section I of this paper, I shall argue against DDE, which purports to disallow PAS but not refusal/withdrawal. I shall argue that since it is permissible for a physician to prescribe morphine to a patient suffering excruciating pain, it is also permissible for her to prescribe such a drug to a patient suffering pain, with the intention that he be killed and hence relieved of the suffering. The grounds on which I rely is the thesis that intention is irrelevant to permissibility, as proposed by Judith Thomson and T.M. Scanlon. In section II, I shall discuss David Velleman’s argument that termination of life is morally impermissible. I proceed to examine in section III the theoretical version of the Slippery Slope Argument. In section IV, I shall consider the practical version of the Slippery Slope Argument. In section V, I shall discuss other consequentialist objections to the legalisation of PAS. In the final section, I shall consider the view that even if PAS is morally permissible, it does not follow that it should be legalised. The argument I consider is the consequentialist one that legalising PAS may have a very different significance—when we consider the total consequences—than if there is only a single act of PAS, considered in isolation. While I agree that consequences are generally very important, I shall argue that we should approach the issue from a contractualist rather than a utilitarian perspective.3. (shrink)

In this paper, I give an account of the conditions for rationally changing your beliefs that respects three constraints; 1) that rational believing is a matter ofrespecting your evidence, 2) that evidence seems to have both objective and subjective features, and (3) that our set of beliefs seem to rationally commit us to certain propositions, regardless of the evidential support we have for these propositions. On the view I outline, rationally believing or giving up a belief is a matter of (...) your inferences tracking your rational commitments, and that these rational commitments account for the evidence you must respect. These rational commitments are subjective in that they are relative to the totality of your beliefs, but also objective in the sense that what counts as a commitment is true for everyone everywhere.
