If you start taking courses in contemporary cognitive science, you will soon encounter a particular picture of the human mind. This picture says that the mind is a lot like a computer. Specifically, the mind is made up of certain states and certain processes. These states and processes interact, in accordance with certain general rules, to generate specific behaviors. If you want to know how those states and processes got there in the first place, the only answer is that they (...) arose through the interaction of other states and processes, which arose from others... until, ultimately, the chain goes back to factors in our genes and our environment. Hence, one can explain human behavior just by positing a collection of mental states and psychological processes and discussing the ways in which these states and processes interact. This picture of the mind sometimes leaves people feeling deeply uncomfortable. They find themselves thinking something like: 'If the mind actually does work like that, it seems like we could never truly be morally responsible for anything we did. After all, we would never be free to choose any behavior other than the one we actually performed. Our behaviors would just follow inevitably from certain facts about the configuration of the states and processes within us.' Many philosophers think that this sort of discomfort is fundamentally confused or wrongheaded. They think that the confusion here can be cleared up just by saying something like: 'Wait! It doesn't make any sense to say that the interaction of these states and processes is preventing you from controlling your own life. The thing you are forgetting is that the interaction of these states and processes – this whole complex system described by cognitive science – is simply you. So when you learn that these states and processes control your behavior, all you are learning is that you are controlling your behavior. There is no reason at all to see these discoveries as a threat to your freedom or responsibility.'2 Philosophers may regard this argument as a powerful one, perhaps even irrefutable.. (shrink)

In this paper, I hope to i. briefly explain Nyaya dualist ontology and identify the implications involved in accepting this view, ii. provide a comparison of Nyaya dualism to Cartesian dualism, and iii. provide an analysis of Nyaya dualism vis-à-vis some contemporary non-dualist theories of mind, in an attempt to gauge the viability of Nyaya Dualism as a theory of mind. I will briefly identify the context and history of this school in Indian Philosophy and will attempt to describe how (...) this paper approaches and interprets Nyaya thinking. (shrink)

The concept of time discounting introduces weights on future goods to make these less valu- able. Famously, both the specic functional form of time discounting and its normative sta- tus are contested. To address these problems, this paper provides a measurement-theoretic framework of representation for time discounting. The general representation theorem char- acterises time discounting factors as ratio-scale representations of dierences in temporally extended prospects. This framework of representation is used to reconsider interpretations of time discounting factors such as time (...) preferences, uncertainty and preference change. It also allows to compare these interpretations with regards to their normative appeal, the kinds of reductionism regarding time and preference they imply and the specic functional form of time discounting they suggest. Farther, multiple-self interpretations of decision-makers become available, such that a time discounting factor represents the degree of connectedness between temporal selves in a person. (shrink)

The concepts of 'ethical' and 'socially responsible' investment (SRI) have become increasingly popular in recent years and funds which offer this kind of investment have attracted many individual inve... merstors. The present book addresses the issue of 'How ought one to invest?' by critically engaging with the ideas of the proponents of this movement about what makes 'ethical' investing ethical. The standard suggestion that ethical investing simply consists in refraining from investing in certain 'morally unacceptable companies' is criticised for being (...) both too rigid (often resting on absolute moral rules which lead to an austere conclusion) and too ineffective for individual investors (investors who after all control only a small part of the investment universe). Furthermore, the idea that ethical investing could consist in engaging more actively with the companies one invests in, in order to make them change their ways and become more socially responsible, is criticised for being just as ineffective for individual investors. Some more radical alternatives are elaborated on and defended - for instance, the suggestion that investors should make as much money from their investments as possible and then donate the proceeds to socially worthwhile charities. From similar suggestions, the common idea that there is no conflict between morality and profitability, or that genuinely ethical investing can be just as profitable as mainstream investing, is criticised for being too naïve. Making a difference may indeed require personal sacrifice of investors, but it is argued that the needs of the possible recipients of philanthropy are morally more important than the luxury of investment returns.

For most us, learning which quantum theory correctly describes human bodies will not affect our attitudes towards our loved ones. On the other hand, a child’s discovery of the nature of meat (or an adult’s discovery of the nature of soylent green) can have a great effect. In still other cases, it is hard to say how one would, or should, react to new information about the underlying nature of what we value—think of how mixed our reactions are to evidence (...) of cultural determinism or atheism, or of how mixed our reactions would be to learning that we all live in the Matrix. (Indeed, maybe there is no objective fact about how we should react. Derek Par t’s ( , section ) fear of death diminished when he became convinced of certain theses about the metaphysics of personal identity. Perhaps there is no objective fact of the matter as to whether this was rational; perhaps it was rational for him but would not be for others.) What can metaphysics contribute to the question of the evil of death? It cannot, on its own, settle the question, since there is no simple rule telling us how to adjust value in light of new information about underlying nature. Given a clear view of the nature of death, there will remain the question of its disvalue. However, metaphysics can help us attain this clear view. Moreover, a clear conception of what metaphysical positions do and don’t say, and a clear conception of how metaphysics works in general, can remove impediments to a rational appraisal of the evil of death.

This dissertation investigates the plausibility of metaethical relativism, or more specifically, what I call “moral truth-value relativism”: the idea that the truth of a moral statement or belief depends on who utters or has it, or who assesses it. According to the most prevalent variants of this view in philosophical literature – “standard relativism” – the truth-values are relative to people’s moralities, often understood as some subset of their affective or desirelike attitudes. Standard relativism has two main contenders: absolutism – (...) the view that the truth-values of moral statements and beliefs do not vary in that way – and non-cognitivism – the view that moral judgements do not have truth-values, since they express affective or desire-like attitudes rather than beliefs. Almost the entire dissertation concerns the plausibility of standard relativism in contrast to absolutism. Part 1 examines first the two main arguments for standard relativism: that it accounts for the connection between moral judgements and motivation (chapter 2), and for the prevalence of diversity of moral opinion (chapter 3). Then the most common objection is considered: that it is inconsistent with the existence of genuine moral disagreements (chapter 4). I argue that these arguments are inconclusive. Both relativism and absolutism can account for the features discussed. Part 2 focuses on the fact that different people have different strongly held intuitions about the relative or absolute nature of morality. I argue that given a common methodological approach in philosophy and metaethics, which takes such intuitions as evidence of correct analyses, this difference in intuitions suggests that neither a relativist nor absolutist analysis can be correct for everyone’s moral judgements. I argue that this result holds both given semantic internalism (chapter 6) and given semantic externalism (chapter 7). To get one single analysis of everyone’s moral judgements we would have to abandon the intuitionbased methodology. In chapter 8, however, I argue that we can maintain this methodology if we accept analysis pluralism, the view that different analyses hold for different people’s moral judgements. (shrink)

Consequentialism is often charged with being self-defeating, for if a person attempts to apply it, she may quite predictably produce worse outcomes than if she applied some other moral theory. Many consequentialists have replied that this criticism rests on a false assumption, confusing consequentialism’s criterion of the rightness of an act with its position on decision procedures. Consequentialism, on this view, does not dictate that we should be always calculating which of the available acts leads to the most good, but (...) instead advises us to decide what to do in whichever manner it is that will lead to the best outcome. Whilst it is typically afforded only a small note in any text on consequentialism, this reply has deep implications for the practical application of consequentialism, perhaps entailing that a consequentialist should eschew calculation altogether.

Review Essay: Dennett’s Sweet Dreams Philosophical Obstacles to a Science of Consciousness.

In this dissertation, I examine the nature and structure of consciousness. Conscious experience is often said to be phenomenally unified, and subjects of consciousness are often self-conscious. I ask whether these features necessarily accompany conscious experience. Is it necessarily the case, for instance, that all of a conscious subject's experiences at a time are phenomenally unified? And is it necessarily the case that subjects of consciousness are self-conscious whenever they are conscious? I argue that the answer to the former is (...) affirmative and the latter negative. In the first chapter, I set the stage by distinguishing phenomenal unity from other species of conscious unity. A pair of conscious states is phenomenally unified if they are experienced together as part of a single experience that encompasses them both. In this and the next two chapters I defend the thesis that, necessarily, for any subject (of conscious mental states) at any time, all of that subject's conscious mental states (at that time) are part of a single, maximal state of consciousness. I call this thesis the "Unity Thesis." I proceed by considering some preliminary questions that might be raised about the Unity Thesis. For instance, the thesis presupposes that it is coherent to talk about parts of mental states. I consider objections by Tye and Searle and argue that the notion of an experiential part is unproblematic. In the remaining pages of the chapter, I present the source of the biggest challenge to the Unity Thesis: the data gathered from split-brain subjects. The Unity Thesis is formulated using the notion of a maximal state of consciousness. In the second chapter, I attempt to precisify this notion in a way that does not pre-emptively decide the debate over the Unity Thesis. In informal terms, a maximal state of consciousness is a sum of conscious states that are i) simultaneous, ii) have the same subject, and iii) all have a conjoint phenomenology. I call this the Consensus View. I then consider two unorthodox views that the Consensus View does not take off the table: the views that a "collective consciousness" and a "spread consciousness" are possible. A collective subject is one that can enjoy the experiences of an indeterminate number of "lesser" subjects of consciousness by sharing them together with those subjects. A spread subject is one that can enjoy the experiences of an indeterminate number of lesser subjects of consciousness, but it does so, not by sharing those experiences with the lesser subjects, but by absorbing the lesser subjects of experience into itself, thereby erasing the traditional boundaries between the entities we intuitively think of as subjects of experience. I argue that, although the Consensus View does not decide against them, these views stretch the bounds of coherence and should not, therefore, be accepted. Having presented an account of what maximal state of consciousness is, I define a stream of consciousness in terms of a maximal states of consciousness. In the rest of chapter two, I consider and argue against a number of different ways of interpreting the split-brain data that are either inconsistent with the Unity Thesis or attribute more than one subject of consciousness to split-brain subjects. Among the views I consider are Lockwood's partial-unity view and the views, by theorists such as Sperry, Koch, Puccetti, Marks, and Tye, that split-brain subjects have two non-overlapping streams of consciousness. In chapter three, I consider a recent attempt by Bayne to account for the split-brain data in a way that does not attribute two streams of consciousness to them. According to Bayne's Switch Model, the consciousness of split-brain subjects can be likened to that of a ball that is passed back and forth between the two hemispheres of the upper-brain. The hemispheres take turns supporting a single stream of consciousness. I consider the empirical data in some detail and argue that the data is not as compatible with the Switch Model as Bayne claims. I close the chapter by presenting the rough outline of an interpretation of the split-brain data that is consistent with both the Unity Thesis and the split-brain data. In chapter four, I turn from defending the Unity Thesis to examining an attempt to account for conscious unity. Rosenthal has offered a theory of conscious unity as an extension of his higher-order theory of consciousness. I consider his account of conscious unity in light of a well-known objection to his theory: the (Representational) Mismatch Objection. It can be asked what it is like for a subject of experience when a higher-order state misrepresents its target first-order state. If what it is like for the subject corresponds to the content of the higher-order state, then it appears as though higher-order representation is unnecessary for conscious experience, for it would appear as though it is possible for a state to be conscious without being represented by a higher-order state. If what it is like corresponds to the content of the lower-order state, then it would again seem as though representation at the higher-order level is unnecessary for conscious experience, for the higher-order state would not seem to be doing any work in generating the experience. I consider and argue against two recent defences of Rosenthal's higher-order theory from the Mismatch Objection. Then I turn to Rosenthal's account of conscious unity. Rosenthal's account posits two mental mechanisms. I refer to the ways of accounting for conscious unity via these two mechanisms as the "gathering strategy" and the "common-ascription strategy" respectively. Both of these strategies, I argue, appear to locate the basis for certain phenomenal facts in higher-order representational facts. This raises a prima facie question: does Rosenthal's account of conscious unity land him square within the sights of the Mismatch Objection? Although the gathering strategy may ultimately be understood in a way that does not make it subject to the Mismatch Objection, Rosenthal has certain commitments that bar this strategy from serving as a complete account of conscious unity. This is problematic for Rosenthal, I argue, because his common-ascription strategy faces some difficult questions. This strategy makes conscious unity due to an implicit expectation a subject of consciousness has that, whenever he or she engages in introspection, an explicit sense of conscious unity will be generated. I argue that it is very difficult to see how such an implicit sense could both avoid the Mismatch Objection and do the work it needs to do in order to account for conscious unity. In chapter five, the discussion turns from the unity of consciousness to self-consciousness. The question that is considered in this and the last chapter is the question whether conscious experience is necessarily accompanied by self-consciousness. The affirmative answer to this question I call the Ubiquity Thesis. I spend some time distinguishing robust conceptions of self-consciousness from minimal conceptions of self-consciousness. The notion of self-consciousness invoked by the Ubiquity Thesis is a minimal one. In spite of the fact that the Ubiquity Thesis invokes only a minimal or thin conception of self-consciousness, I believe the thesis to be false and argue against it. In this chapter I take up the views of Husserl. Husserl is often regarded as the progenitor of the phenomenological tradition, a tradition in which many philosophers affirm the Ubiquity Thesis. I examine and argue against an interpretation of Husserl's work, one defended by Zahavi, according to which Husserl could be seen to defend the Ubiquity Thesis. One claim that Husserl makes is that, in order for an object to become the intentional target of a conscious state, it must be given to consciousness beforehand. It is possible, during acts of deliberate introspection, for consciousness to take itself as its object. On Husserl's view, this requires consciousness to be given to itself beforehand. This self-givenness of consciousness, argues Zahavi, can be seen as a kind of minimal self-consciousness. Husserl has also offered an account of this self-givenness of consciousness and it appears in his discussion of inner time-consciousness. I attempt to argue, using some of Husserl's other views regarding psychological stances (or standpoints), that consciousness is not given to itself outside of the adoption of a certain psychological standpoint. I also offer an alternative way of accounting for inner time-consciousness, one that does not have, as a built-in feature, that consciousness always has itself as a secondary object. In the sixth and final chapter, I take up a contemporary defence of the Ubiquity Thesis. Kriegel, a higher-order theorist like Rosenthal, has argued that every conscious state is conscious in virtue of the fact that it represents itself. This self-representation is understood as a kind of self-consciousness and, thus, his theory can be seen as affirming the Ubiquity Thesis. In the first part of the chapter, I take issue with the way in which Kriegel lays out the conceptual terrain. In particular, Kriegel countenances a property he calls "intransitive state self-consciousness." I argue that this way of speaking is confused. I then turn to considering Kriegel's account. Kriegel identifies the species of self-consciousness that pervades all of conscious experience with a peripheral awareness of one's own mental states. I argue that such a peripheral inner awareness does not accompany all of our mental states and, thus, that Kriegel's views do not give us reason to accept the Ubiquity Thesis. (shrink)

Thomas Metzinger argues that phenomenal selves are appearances produced by the ongoing operations of a “self-model” that simulates, emulates, and represents aspects of the system’s states to itself – and not substantial things. In this essay, I explain the nature of phenomenal selfhood and then describe the most important problem that arises in connection with explaining phenomenal selfhood. I then argue that, by itself, the self-model theory of subjectivity lacks sufficient resources to wholly solve this problem and that Metzinger’s argument (...) does not justify his ontological conclusions about selves.

Rationality appears to have some intimate relation with normativity: exactly what relation is in dispute. John Broome devotes a chapter of his recent book to rebutting the view that rationality has 'true' normativity, which he equates with the kind of normativity that I call directivity. In particular, he offers a number of arguments against derivative accounts of thenormativity of rationality. In this paper I defend my instrumentalist account from those arguments. In so doing I bring into view the grounds of (...) a live positive defence of rationality’s servanthood to directivity. (shrink)

This article critically surveys the current bioethical and politico-philosophical debate about the ethical permissibility of a so-called ‘liberal eugenics’ and argues that neither the liberal argument for nor the liberal argument against human genetic enhancement is internally consistent as, ultimately, each ends up violating the very liberal principles it nonetheless pretends to defend. In particular, it will be shown that while the argument against a new eugenics necessarily entails a preemptive dehumanization of any potential enhanced form of life, the argument (...) for it threatens to reduce any non-enhanced form of life to a “wrongful life” or a life not worth living. It will therefore be concluded that the specific stakes of this contentious issue cannot be grasped within a liberal conceptual framework. (shrink)

Economic Theory normally assumes the so-called homo economicus, a consequential model of rationality. We highlight the main features of this model in opposition to deontology: axiological homogeneity, maximization and agent neutrality. Amartya Sen’s criticism of standard consequentialism copes to those features, and includes commitment and duty in the economic rationality. We analyze his concept of preference to ascertain how far economic rationality can thus go in the direction of deontology. We conclude that, though diminished, the difference between them still remains.

The goal of this article is to present a first list of ethical concerns that may arise from research and personal use of virtual reality (VR) and related technology, and to offer concrete recommendations for minimizing those risks. Many of the recommendations call for focused research initiatives. In the first part of the article, we discuss the relevant evidence from psychology that motivates our concerns. In Section “Plasticity in the Human Mind,” we cover some of the main results suggesting that (...) one’s environment can influence one’s psychological states, as well as recent work on inducing illusions of embodiment. Then, in Section “Illusions of Embodiment and Their Lasting Effect,” we go on to discuss recent evidence indicating that immersion in VR can have psychological effects that last after leaving the virtual environment. In the second part of the article, we turn to the risks and recommendations. We begin, in Section “The Research Ethics of VR,” with the research ethics of VR, covering six main topics: the limits of experimental environments, informed consent, clinical risks, dual-use, online research, and a general point about the limitations of a code of conduct for research. Then, in Section “Risks for Individuals and Society,” we turn to the risks of VR for the general public, covering four main topics: long-term immersion, neglect of the social and physical environment, risky content, and privacy. We offer concrete recommendations for each of these 10 topics, summarized in Table 1. (shrink)

What happens when machines become more intelligent than humans? One view is that this event will be followed by an explosion to ever-greater levels of intelligence, as each generation of machines creates more intelligent machines in turn. This intelligence explosion is now often known as the “singularity”. The basic argument here was set out by the statistician I.J. Good in his 1965 article “Speculations Concerning the First Ultraintelligent Machine”: Let an ultraintelligent machine be defined as a machine that can far (...) surpass all the intellectual activities of any man however clever. Since the design of machines is one of these intellectual activities, an ultraintelligent machine could design even better machines; there would then unquestionably be an “intelligence explosion”, and the intelligence of man would be left far behind. Thus the first ultraintelligent machine is the last invention that man need ever make. The key idea is that a machine that is more intelligent than humans will be better than humans at designing machines. So it will be capable of designing a machine more intelligent than the most intelligent machine that humans can design. So if it is itself designed by humans, it will be capable of designing a machine more intelligent than itself. By similar reasoning, this next machine will also be capable of designing a machine more intelligent than itself. If every machine in turn does what it is capable of, we should expect a sequence of ever more intelligent machines. This intelligence explosion is sometimes combined with another idea, which we might call the “speed explosion”. The argument for a speed explosion starts from the familiar observation that computer processing speed doubles at regular intervals. Suppose that speed doubles every two years and will do so indefinitely. Now suppose that we have human-level artificial intelligence 1 designing new processors. Then faster processing will lead to faster designers and an ever-faster design cycle, leading to a limit point soon afterwards. The argument for a speed explosion was set out by the artificial intelligence researcher Ray Solomonoff in his 1985 article “The Time Scale of Artificial Intelligence”.1 Eliezer Yudkowsky gives a succinct version of the argument in his 1996 article “Staring at the Singularity”: “Computing speed doubles every two subjective years of work..

Empathy is intersubjective in that it connects us mentally with others. Some theorists believe that by blurring the distinction between self and other empathy can provide a radical form of altruism that grounds all of morality and even a kind of immortality. Others are more pessimistic and maintain that in distorting the distinction between self and other empathy precludes genuine altruism. Even if these positions exaggerate self-other merging, empathy’s intersubjectivity can perhaps ground ordinary altruism and the rational recognition that one (...) shouldn’t arbitrarily privilege oneself over others.

This chapter aims to present a theoretical survey of political representation of future generations. The chapter focuses on two main normative justifications of representation of future generations. The first appeals to intergenerational justice and the second to democratic legitimacy. Then, the chapter addresses possible objections to the representation of future generations. These objections are: first, we should prevent the inflation of representation; second, representation of future people is not really political representation; third, representation of future people is unnecessary. The next (...) part discusses theoretical proposals to represent future generations in existing institutions. An appendix provides an overview of past and present real-world experiments, including the Finnish Committee for the Future, the Israeli Knesset Commissioner for Future Generations (2001–2006) and the Hungarian Ombudsman for Future Generations.

This is a bibliography of books and articles on consciousness in philosophy, cognitive science, and neuroscience over the last 30 years. There are three main sections, devoted to monographs, edited collections of papers, and articles. The first two of these sections are each divided into three subsections containing books in each of the main areas of research. The third section is divided into 12 subsections, with 10 subject headings for philosophical articles along with two additional subsections for articles in cognitive (...) science and neuroscience. Of course the division is somewhat arbitrary, but I hope that it makes the bibliography easier to use. This bibliography has first been compiled by Thomas Metzinger and David Chalmers to appear in print in two philosophical anthologies on conscious experience . From 1995 onwards it has been continuously updated by Thomas Metzinger, and now is freely available as a PDF-, RTF-, or HTML-file. This bibliography mainly attempts to cover the Anglo-Saxon and German debates, in a non-annotated, fully formatted way that makes it easy to "cut and paste" from the original file. To a certain degree this bibliography also contains items in other languages than English and German - all submissions in other languages are welcome. Last update of current version: July 13th, 2001.

The analysis and theorizing about concepts like “knowledge” and “justification” has played a central role in much of epistemology in the past half century. This dissertation argues for the claim that we should understand this conceptual concern as one of design. Concepts are tools and the concepts of interest to epistemologists must be those that we can best use in service of our epistemic interests. On this understanding of the conceptual project, we determine the content of epistemic concepts, not by (...) consulting our naïve linguistic intuitions, but by determining what concepts will best help us express and enforce the epistemic norms that serve our interests. The determination of what concepts will do this job best will pull on information from many empirical sources like psychology and sociology. It will also require some means of determining what our epistemic interests are. In defending this view of the methodology of epistemology, we examine how one might go about designing and thinking about the purposes of an example epistemic concept: “epistemic ought”. We also consider how thinking about things from a design prospective can help in the determination of our epistemic interests by considering how design considerations feature in the debate between scientific realism and anti-realism. We also examine and respond to a few potential problems for this methodological view from Selim Berker’s arguments against epistemic teleology to problems with the design method’s potentially problematically self-undermining or self-reinforcing character.

Recent work on probability in the Everett interpretation of quantum mechanics yields a decision-theoretic derivation of David Lewis’ Principal Principle, and hence a general metaphysical theory of probability; part 1 is a discussion of this remarkable result. I defend the claim that the ‘subjective uncertainty’ principle is required for the derivation to succeed, arguing that it amounts to a theoretical identification of chance. In part 2, I generalize this account, and suggest that the Everett interpretation, in combination with a plausible (...) view of natural laws, has the potential to provide a reductive theory of metaphysical modality. I defend the resulting naturalistic modal realism, and outline some of its implications for other parts of metaphysics. (shrink)

I develop and defend a version of what I call Disposition-Based Decision Theory (or DBDT). I point out important problems in David Gauthier’s (1985, 1986) formulation of DBDT, and carefully develop a more defensible formulation. I then compare my version of DBDT to the currently most widely accepted decision theory, Causal Decision Theory (CDT). Traditional intuition-based arguments fail to give us any strong reason to prefer either theory over the other, but I propose an alternative strategy for resolving this debate. (...) I argue that we should embrace DBDT because it does better than CDT at the work that we, as a matter of empirical fact, commonly call upon a notion of rationality to do. (shrink)

We consider an approach to some philosophical problems that I call the Method of Conceptual Articulation: to recognize that a question may lack any determinate answer, and to re-engineer concepts so that the question acquires a definite answer in such a way as to serve the epistemic motivations behind the question. As a case study we examine “Galileo’s Paradox”, that the perfect square numbers seem to be at once as numerous as the whole numbers, by one-to-one correspondence, and yet less (...) numerous, being a proper subset. I argue that Cantor resolved this paradox by a method at least close to that proposed—not by discovering the true nature of cardinal number, but by articulating several useful and appealing extensions of number to the infinite. Galileo was right to suggest that the concept of relative size did not apply to the infinite, for the concept he possessed did not. Nor was Bolzano simply wrong to reject Hume’s Principle (that one-to-one correspondence implies equal number) in the infinitary case, in favor of Euclid’s Common Notion 5 (that the whole is greater than the part), for the concept of cardinal number (in the sense of “number of elements”) was not clearly defined for infinite collections. Order extension theorems now suggest that a theory of cardinality upholding Euclid’s principle instead of Hume’s is possible. Cantor’s refinements of number are not the only ones possible, and they appear to have been shaped by motivations and fruitfulness, for they evolved in discernible stages correlated with emerging applications and results. Galileo, Bolzano, and Cantor shared interests in the particulate analysis of the continuum and in physical applications. Cantor’s concepts proved fruitful for those pursuits. Finally, Gödel was mistaken to claim that Cantor’s concept of cardinality is forced on us; though Gödel gives an intuitively compelling argument, he ignores the fact that Euclid’s Common Notion is also intuitively compelling, and we are therefore forced to make a choice. The success of Cantor’s concept of cardinality lies not in its truth (for concepts are not true or false), nor its uniqueness (for it is not the only extension of number possible), but in its intuitive appeal, and most of all, its usefulness to the understanding.

My thesis demonstrates that, despite a number of impossibility results, a satisfactory and coherent theory of population ethics is possible. It achieves this by exposing and undermining certain key assumptions that relate to the nature of welfare and personal identity. I analyse a range of arguments against the possibility of producing a satisfactory population axiology that have been proposed by Derek Parfit, Larry Temkin, Tyler Cowen and Gustaf Arrhenius. I conclude that these results pose a real and significant challenge. However, (...) in the absence of further evidence I reject the conclusion that they imply that the value of populations is either not precise or not transitive. Instead, I expose some fundamental assumptions behind these results. One key assumption is that something can only make a life better or worse if it makes that life better or worse for the person living it, i.e. it raises or lowers the ‘welfare level’ of that life. Although intuitively highly plausible, this assumption ignores the possibility that perspectives other than that of the person living a life may be relevant for evaluating the components of that life and that these should be incorporated into our all things considered judgements. I argue that episodes within a person’s life that are strongly psychologically connected may have a special normative significance, particularly if these episodes involve such things as the enjoyment of ‘the best things in life’ or the experience of great suffering. We have reason to assign an all things considered value to such strongly psychologically connected phases of a person’s life, where this value is not exhausted by the contributions these make to the welfare level of that person’s life as a whole. It follows that our all things considered evaluations of populations are often underdetermined by information about the welfare levels of the lives they contain. However, in certain cases, most notably in that of ‘the Repugnant Conclusion’, there is nevertheless sufficient information provided by the welfare levels of persons’ lives to allow us to infer facts about these components that make an all things considered difference to these evaluations. I argue that a failure to acknowledge these facts is the cause of the aforementioned impossibility results and that once they are taken into account it is possible to produce a satisfactory theory of population ethics.

This paper examines causal theories of reference with respect to how plausible an account they give of non-physical natural kind terms such as ‘gene’ as well as of the truth of the associated theoretical claims. I first show that reference fixism for ‘gene’ fails. By this, I mean the claim that the reference of ‘gene’ was stable over longer historical periods, for example, since the classical period of transmission genetics. Second, I show that the theory of partial reference does not (...) do justice to some widely held realist intuitions about classical genetics. This result is at loggerheads with the explicit goals usually associated with partial theories of reference, which is to defend a realist semantics for scientific terms. Thirdly, I show that, contrary to received wisdom and perhaps contrary to physics and chemistry, neither reference fixism nor partial reference are necessary in order to hold on to scientific realism about biology. I pinpoint the reasons for this in the nature of biological kinds, which do not even remotely resemble natural kinds (i.e., Lockean real essences) as traditionally conceived. (shrink)

This thesis is about what a normative reason is and how reasons relate to oughts. I argue that normative reasons are to be understood as relational properties of favouring or disfavouring. I then examine the question: What is the relation between reasons, so understood, and what we ought to do, believe, or feel? I argue that the relation is an explanatory one. We should explain what we ought to do in terms of reasons, and not the other way around. This (...) view faces a number of difficulties, in particular in accounting for supererogatory acts and the distinction between an action being required and an action being recommended. The analysis that I provide explains how we can solve these problems. In providing such an analysis, this thesis aims to be a contribution to the discussion of how we might elucidate the structure of what is sometimes called normativity. (shrink)

I consider whether evolutionary explanations can debunk our moral beliefs. Most contemporary discussion in this area is centred on the question of whether debunking implications follow from our ability to explain elements of human morality in terms of natural selection, given that there has been no selection for true moral beliefs. By considering the most prominent arguments in the literature today, I offer reasons to think that debunking arguments of this kind fail. However, I argue that a successful evolutionary debunking (...) argument can be constructed by appeal to the suggestion that our moral outlook reflects arbitrary contingencies of our phylogeny, much as the horizontal orientation of the whale’s tail reflects its descent from terrestrial quadrupeds. An introductory chapter unpacks the question of whether evolutionary explanations can debunk our moral beliefs, offers a brief historical guide to the philosophical discussion surrounding it, and explains what I mean to contribute to this discussion. Thereafter follow six chapters and a conclusion. The six chapters are divided into three pairs. The first two chapters consider what contemporary scientific evidence can tell us about the evolutionary origins of morality and, in particular, to what extent the evidence speaks in favour of the claims on which debunking arguments rely. The next two chapters offer a critique of popular debunking arguments that are centred on the irrelevance of moral facts in natural selection explanations. The final chapters develop a novel argument for the claim that evolutionary explanations can undermine our moral beliefs insofar as they show that our moral outlook reflects arbitrary contingencies of our phylogeny. A conclusion summarizes my argument and sets out the key questions that arise in its wake. (shrink)

In this paper, I examine the conflicts between autonomy and justice. The problem of justice in healthcare concerns both micro-allocation and macro-allocation. The latter has to do with distributive justice: who should get what healthcare resources at whose expense. The current debate about healthcare reform brings up two competing models of distributive justice from political philosophy. The libertarian theory holds to the ideal of individual responsibility and choice, viewing taxation for the purpose of providing goods to those who cannot afford (...) them as a form of unjustified coercion. The liberal theory holds that society should ensure that all members are provided with basic goods that correct for inequalities that deprive them of human dignity. Even though both theories value individual choice, these theories provide opposing answers to the question of whether taxes should be collected and used for the purpose of ensuring universal access to healthcare. In my paper, I show that neither theory can respect patient choice in healthcare and achieve distributive justice. Libertarians ignore the realities of the healthcare system and why a free market where patients choose and pay for what they want cannot exist. Liberals face the problem that the choices that patients make can lead to over-consumption of healthcare at the expense of other goods important to society. (shrink)

A high level of confidence in the identity of individuals is required to let them die as ordered by an advance directive. Thus, if we are animalists, then we should lack the confidence required to apply lethal advance directives to the cheerfully demented, or so I argue. In short, there is consensus among animalists that the best way to avoid serious objections to their account is to adopt an ontology that denies the existence of brains, hands, tables, chairs, iced-tea, and (...) lemonade. The adoption of such an ontology reduces the justificatory force of commonsense, which is key in arguing that we are animals and that we persist as long as we are biologically alive. With this loss of justification comes the loss of a high level of confidence that Quinn-pre-dementia’s lethal advanced directive applies to Quinn-post-dementia, via identity. If we do not have a high level of confidence that Quinn-pre-dementia’s advanced directive applies to Quinn-post- dementia, then it is not enough (on its own) to let Quinn-post-dementia die. (shrink)

An extended analysis is given of the program, originally suggested by Deutsch, of solving the probability problem in the Everett interpretation by means of decision theory. Deutsch's own proof is discussed, and alternatives are presented which are based upon different decision theories and upon Gleason's Theorem. It is argued that decision theory gives Everettians most or all of what they need from `probability'. Contact is made with Lewis's Principal Principle linking subjective credence with objective chance: an Everettian Principal Principle is (...) formulated, and shown to be at least as defensible as the usual Principle. Some consequences of (Everettian) quantum mechanics for decision theory itself are also discussed. -/- [NB: this this long (70 pages) and occasionally rambling online-only paper has been almost entirely superseded by material in subsequent; if something is not included in them it usually means that I have had second thoughts.

In this article we explore the underpinnings of what we view as a recent" backlash" in English law, a judicial reaction against considering children's and young people's expressions of their own feelings about treatment as their" true" wishes. We use this case law as a springboard to conceptual discussion, rooted in (a) empirical psychological work on child development and (b) three key philosophical ideas: rationality, autonomy and identity.

This paper makes a transcendental argument. It assumes the normative validity of the instrumental principle, and then investigates the conditions of its validity. Ultimately, it argues that there are three necessary conditions for its validity. Firstly, agents must be rationally capable of regarding themselves as having a single self that possesses the same reasons, ends, and means. Secondly, agents must be rationally capable of distinguishing themselves from other selves that possess ends. Thirdly, these two conditions must actually obtain, which means (...) that we must have a self that has the same reasons, ends, and means, and that such selves must be distinct from one another. The paper fields two arguments in support of these three conditions and then offers an interpretation of the arguments to show that they vindicate all three conditions. (shrink)

Exponential discounted utility theory provides the normative standard for future discounting as it is employed throughout the social sciences. Tracing the justification for this standard through economics, philosophy and psychology, I’ll make what I believe is the best case one can for it, showing how a non-arbitrariness assumption and a dominance argument together imply that discounting ought to be exponential. Ultimately, however, I don’t find the case compelling, as I believe it is deeply flawed. Non-exponential temporal discounting is often rational–indeed, (...) the paragon of rationality. If this is correct, it’s an important point when considering policy interventions. Instead of trying to “fix” non-exponetial discounting because it is irrational and associated with negative life outcomes, we might instead focus attention on why the conditions obtain that make such discounting rational.

I present an argument for panpsychism: the thesis that everything is conscious, or at least that fundamental physical entities are conscious. The argument takes a Hegelian dialectical form. Panpsychism emerges as a synthesis of the thesis of materalism and the antithesis of dualism. In particular, the key premises of the causal argument for materialism and the conceivability argument for dualism are all accommodated by a certain version of panpsychism. This synthesis has its own antithesis in turn: panprotopsychism, the thesis that (...) fundamental physical entities are protoconscious, also accommodates the key premises. Panpsychism and panprotopsychism are synthesized under Russellian monism, and then face an antithesis, the combination problem. The question of whether there is a new synthesis remains open.

This is a preliminary version of an article to appear in the forthcoming Ashgate Companion to the New Philosophy of Physics.In it, I aim to review, in a way accessible to foundationally interested physicists as well as physics-informed philosophers, just where we have got to in the quest for a solution to the measurement problem. I don't advocate any particular approach to the measurement problem (not here, at any rate!) but I do focus on the importance of decoherence theory to (...) modern attempts to solve the measurement problem, and I am fairly sharply critical of some aspects of the "traditional" formulation of the problem.

The rich resources of the Four-Dimensional metaphysics have been brought to bear upon many traditional philosophical problems in recent years. Alas, the implications of Four-Dimensionalism for bioethics have gone largely unexplored. Hud Hudson is the rare exception. Relying upon a Four- Dimensional metaphysics of temporal parts and a belief in unrestricted composition, he argues that there is little reason to identify the perduring human embryonic animal and the perduring human person. He makes the intriguing claim that if abortion is wrong, (...) then it is not because the human animal within its mother’s womb is a person. This he rightly claims “is a very significant result” for “an overwhelming amount of the literature on abortion and infanticide (as well as much of the public debate on these topics) seems to turn on the question of whether or not the human fetus is a person.” [3, p. 153].

I investigate the consequences for semantics, and in particular for the semantics of tense, if time is assumed to have a branching structure not out of metaphysical necessity (to solve some philosophical problem) but just as a contingent physical fact, as is suggested by a currently-popular approach to the interpretation of quantum mechanics.

În acest eseu evidențiez principalele aspecte psihologice și filosofice desprinse din filmul Solaris regizat de Andrei Tarkovski, precum și tehnicile cinematografice utilizate de regizor pentru a-și transmite mesajele spectatorului. În ”Introducere” prezint pe scurt elementele relevante din biografia lui Tarkovski și o prezentare generală a romanului Solaris a lui Stanislav Lem și filmul Solaris în regia lui Andrei Tarkovsky. În ”Tehnica cinematografică” vorbesc despre ritmul specific al scenelor, mișcarea radicală declanșată de Tarkovsky în cinematografia modernă, rolul elementelor simbolice și iconice, (...) , și afinitățile cu zona fantastică a literaturii ruse. În ”Aspecte psihologice” analizez problema comunicării într-o societate umană a viitorului considerată de Tarkovsky ca rigidă, obsesia casei, și evoluția personală a lui Kris, Hari, și a relațiilor dintre ei. În ”Aspecte filosofice” se analizează filmul prin prisma filosofiei minții (dualismul cartezian, reducționismul și funcționalismul), a problemei identității personale, a teoriei spațiilor heterotopice dezvoltată de Michel Foucault, și interpretările semantice care se pot deduce din film. De asemenea, se analizează problema identității personale prin prisma filosofiei lui Locke. ”Concluziile” expun ideile generale rezultate din acest eseu, respectiv că Tentativele omului de a clasifica și de a păstra forme de interacțiune cu entități necunoscute vor fi întotdeauna condamnate la eșec și vor reflecta o greșeală majoră în lumea panoptică în care trăim. În acest cadru de analiză a filosofiei minții, funcționalismul pare a fi cel mai intuitiv. Solaris este, totuși, un film care începe ca o căutare a răspunsurilor și ajunge să ofere aceste răspunsuri împreună cu o serie de întrebări cu totul diferite. (shrink)

It is a commonplace that there are limits to the ways we can permissibly treat people, even in the service of good ends. For example, we may not steal someone’s wallet, even if we plan to donate the contents to famine relief, or break a promise to help a colleague move, even if we encounter someone else on the way whose need is somewhat more urgent. In other words, we should observe certain constraints against mistreating people, where a constraint is (...) a moral principle that we should not violate, even when that is the only way to prevent further, similar violations or other, greater evils. But, despite its intuitive appeal, the view that there are constraints has drawn considerable criticism, and attempts to provide a rationale for constraints have been, at best, substantially incomplete. In this paper, I develop a novel rationale for constraints that fills important gaps left by views in the literature. The account helps make sense of constraints by identifying a morally significant relation that we bear to people when, and only when, we observe certain constraints against mistreating them. Put roughly, observing these constraints is a condition for being worthy of a form of trust that I call civic trust, and being worthy of such trust is an essential part of living with others in the sort of harmony that characterizes morally permissible interaction. By focusing, in ways other accounts do not, on the role that observing constraints plays in our psychological lives, this approach not only makes the structure of constraints more intelligible, but also helps us better appreciate the force of our reason to observe constraints, and better understand the kind of moral community to which we should aspire.

This article addresses the debate on fuzzy cases concerning the so called ‘mild’ and sporadic instances of physical violence against children by caregivers. The end of violence toward children is a current goal in the international scenario. However, myths on the use of violence and the scope of parental rights still survive. Thus, I examine the main theoretical, ethical and political challenges regarding conceptual clear-cut boun- daries and the burden of proof when justifying violence. Finally, I defend the role of (...) a preventive approach on children’s wellbeing and family intervention as a fruitful way to surpass polarized debates on permi- ssibility and criminalization.

In this study I analyse the performance of a democratic decision-making rule: the weighted majority rule. It assigns to each voter a number of votes that is proportional to her stakes in the decision. It has been shown that, for collective decisions with two options, the weighted majority rule in combination with self-interested voters maximises the common good when the latter is understood in terms of either the sum-total or prioritarian sum of the voters’ well-being. The main result of my (...) study is that this argument for the weighted majority rule — that it maximises the common good — can be improved along the following three main lines. (1) The argument can be adapted to other criteria of the common good, such as sufficientarian, maximin, leximin or non-welfarist criteria. I propose a generic argument for the collective optimality of the weighted majority rule that works for all of these criteria. (2) The assumption of self-interested voters can be relaxed. First, common-interest voters can be accommodated. Second, even if voters are less than fully competent in judging their self-interest or the common interest, the weighted majority rule is weakly collectively optimal, that is, it almost certainly maximises the common good given large numbers of voters. Third, even for smaller groups of voters, the weighted majority rule still has some attractive features. (3) The scope of the argument can be extended to decisions with more than two options. I state the conditions under which the weighted majority rule maximises the common good even in multi-option contexts. I also analyse the possibility and the detrimental effects of strategic voting. Furthermore, I argue that self-interested voters have reason to accept the weighted majority rule. (shrink)

Climate change appears to be a classic aggregation problem, in which billions of individuals perform actions none of which seem to be morally wrong taken in isolation, and yet which combine to drive the global concentration of greenhouse gases (GHGs) ever higher toward environmental (and humanitarian) catastrophe. When an individual can choose between actions that will emit differing amounts of GHGs―such as to choose a vegan rather than carnivorous meal, to ride a bike to work rather than drive a car, (...) or to take a reusable bag to the supermarket rather than send another plastic bag to landfill―does she have any reason to choose the lower-emitting actions? In this chapter I'll reject the claim that individuals don't make a difference when it comes to climate change. I first discuss making a difference with every action, as a way of getting clearer about how individuals' actions impact causally on the harms resulting from climate change, making a distinction so far overlooked in the climate ethics discussion between 'macro' thresholds like ice-cap melt, and 'micro' thresholds like severe weather events. I set aside making a difference with every action as implausible, and then move on to discuss both low probability of major difference, and high probability of minor difference. I argue that both of these are plausible characterizations of individuals' causal contributions to climate change. I conclude by noting some policy implications of having (probabilistic) individual difference-making back in play. (shrink)

Distributive egalitarians believe that distributive justice is to be explained by the idea of distributive equality (DE) and that DE is of intrinsic value. The socio-relational critique argues that distributive egalitarianism does not account for the “true” value of equality, which rather lies in the idea of “equality as a substantive social value” (ESV). This paper examines the socio-relational critique and argues that it fails because – contrary to what the critique presupposes –, first, ESV is not conceptually distinct from (...) DE, and second, the idea of ESV cannot serve as a “foundation” or “root” of distributive egalitarianism. (shrink)

In this paper, I outline the cumulative network model of the self. This model articulates the self as relational, recognizing social relations as constitutive of the self. The theory arises out of concerns about the individualistic paradigms of two main frameworks in the analytic philosophical literature on personal identity, namely, the psychological and the animalist approaches to personhood and is explicitly inspired by feminist theories on relational autonomy and self. I argue that “relationality” is not only social, but that the (...) self is relational throughout, psychologically, physically, biologically, culturally, semantically, as well as socially. Hence, the self is a network of relations. The model also aims to recognize that temporality or historicity is constitutive of the self, that the self is a process, not a static three-dimensional thing. Hence, the self is a cumulative network. (shrink)

Normative reasons are of constant importance to us as agents trying to navigate through life. For this reason it is natural and vital to ask philosophical questions about reasons and the normative realm. This thesis explores various issues concerning reasons and normativity. The thesis consists of five free-standingpapers and an extended introduction. The aim of the extended introduction is not merely to situate the papers within a wider philosophical context but also to provide an overview of some of the central (...) research questions concerning reasons and normativity. The introduction is divided into five chapters. Chapter 1 introduces and outlines the dissertation. Chapter 2 concerns the issue of what a reason is and what different types of reasons there are, such as pro tanto reasons and overall reasons. Chapter 3 discusses the frequently employed weighing metaphor, i.e. that reasons have a certain weight and can be weighed against the weight of other reasons. Chapter 4 covers how reasons relate to other normative notions such as ought, value, and obligation. For example, it discusses whether it is the case that for something to be valuable just is for there to be reasons to favor it. Chapter 5 concludes the introduction by briefly exploring how it all relates.The thesis can be said to be embedded in a recent research trend within philosophy of normativity that has a distinguished focus on reasons.The five papers deal with various issues concerning reasons and normativity. Paper I argues for a novel and theoretically parsimonious way to understand background conditions for values and reasons. Paper II explores an interpretation of the distinction between subjectivism and objectivism about reasons and value so as to accommodate that the distinction does not commit either party to certain first order claims about what reasons there are or what makes objects valuable. Paper III discusses the dictum ‘ought implies can’and how to properly interpret the ‘can’. Paper IV defends principles according to which what we ought and have reasons to do transmit from ends to the necessary means of that action. Paper V analyzes how the Fitting Attitudes analysis of value should best understand degrees of value. (shrink)

Purpose This paper aims to formalize long-term trajectories of human civilization as a scientific and ethical field of study. The long-term trajectory of human civilization can be defined as the path that human civilization takes during the entire future time period in which human civilization could continue to exist. -/- Design/methodology/approach This paper focuses on four types of trajectories: status quo trajectories, in which human civilization persists in a state broadly similar to its current state into the distant future; catastrophe (...) trajectories, in which one or more events cause significant harm to human civilization; technological transformation trajectories, in which radical technological breakthroughs put human civilization on a fundamentally different course; and astronomical trajectories, in which human civilization expands beyond its home planet and into the accessible portions of the cosmos. -/- Findings Status quo trajectories appear unlikely to persist into the distant future, especially in light of long-term astronomical processes. Several catastrophe, technological transformation and astronomical trajectories appear possible. -/- Originality/value Some current actions may be able to affect the long-term trajectory. Whether these actions should be pursued depends on a mix of empirical and ethical factors. For some ethical frameworks, these actions may be especially important to pursue. (shrink)

Despite the impressive progress that has been made on both the empirical and conceptual fronts of boredom research, there is one facet of boredom that has received remarkably little attention. This is boredom's relationship to morality. The aim of this article is to explore the moral dimensions of boredom and to argue that boredom is a morally relevant personality trait. The presence of trait boredom hinders our capacity to flourish and in doing so hurts our prospects for a moral life. (...) -/- . (shrink)
