Positions on the ethics of human enhancement technologies can be (crudely) characterized as ranging from transhumanism to bioconservatism. Transhumanists believe that human enhancement technologies should be made widely available, that individuals should have broad discretion over which of these technologies to apply to themselves, and that parents should normally have the right to choose enhancements for their children-to-be. Bioconservatives (whose ranks include such diverse writers as Leon Kass, Francis Fukuyama, George Annas, Wesley Smith, Jeremy Rifkin, and Bill McKibben) are generally (...) opposed to the use of technology to modify human nature. A central idea in bioconservativism is that human enhancement technologies will undermine our human dignity. To forestall a slide down the slippery slope towards an ultimately debased ‘posthuman’ state, bioconservatives often argue for broad bans on otherwise promising human enhancements. This paper distinguishes two common fears about the posthuman and argues for the importance of a concept of dignity that is inclusive enough to also apply to many possible posthuman beings. Recognizing the possibility of posthuman dignity undercuts an important objection against human enhancement and removes a distortive double standard from our field of moral vision. (shrink)

In the generative tradition, the language faculty has been shrinking—perhaps to include only the mechanism of recursion. This paper argues that even this view of the language faculty is too expansive. We first argue that a language faculty is difficult to reconcile with evolutionary considerations. We then focus on recursion as a detailed case study, arguing that our ability to process recursive structure does not rely on recursion as a property of the grammar, but instead emerges gradually by piggybacking on (...) domain-general sequence learning abilities. Evidence from genetics, comparative work on non-human primates, and cognitive neuroscience suggests that humans have evolved complex sequence learning skills, which were subsequently pressed into service to accommodate language. Constraints on sequence learning therefore have played an important role in shaping the cultural evolution of linguistic structure, including our limited abilities for processing recursive structure. Finally, we re-evaluate some of the key considerations that have often been taken to require the postulation of a language faculty. (shrink)

Epistemologists spend a great deal of time thinking about how we should respond to our evidence. They spend far less time thinking about the ways that evidence can be acquired in the first place. This is an oversight. Some ways of acquiring evidence are better than others. Many normative epistemologies struggle to accommodate this fact. In this article I develop one that can and does. I identify a phenomenon – epistemic feedback loops – in which evidence acquisition has gone awry, (...) with the result that even beliefs based on the evidence are irrational. Examples include evidence acquired under the influence of confirmation bias and evidence acquired under the influence of cognitively penetrated experiences caused by implicit bias. I then develop a theoretical framework which enables us to understand why beliefs that are the outputs of epistemic feedback loops are irrational. Finally, I argue that many popular approaches to epistemic normativity may need to be abandoned on the grounds that they cannot comfortably explain feedback loops. The scope of this last claim is broad: it includes almost all contemporary theories of justified/rational belief and of the epistemology of cognitive penetration. (shrink)

Suppose that we develop a medically safe and affordable means of enhancing human intelligence. For concreteness, we shall assume that the technology is genetic engineering (either somatic or germ line), although the argument we will present does not depend on the technological implementation. For simplicity, we shall speak of enhancing “intelligence” or “cognitive capacity,” but we do not presuppose that intelligence is best conceived of as a unitary attribute. Our considerations could be applied to specific cognitive abilities such as verbal (...) fluency, memory, abstract reasoning, social intelligence, spatial cognition, numerical ability, or musical talent. It will emerge that the form of argument that we use can be applied much more generally to help assess other kinds of enhancement technologies as well as other kinds of reform. However, to give a detailed illustration of how the argument form works, we will focus on the prospect of cognitive enhancement. (shrink)

Transhumanism is a loosely defined movement that has developed gradually over the past two decades. [1] It promotes an interdisciplinary approach to understanding and evaluating the opportunities for enhancing the human condition and the human organism opened up by the advancement of technology. Attention is given to both present technologies, like genetic engineering and information technology, and anticipated future ones, such as molecular nanotechnology and artificial intelligence.

The ethical issues related to the possible future creation of machines with general intellectual capabilities far outstripping those of humans are quite distinct from any ethical problems arising in current automation and information systems. Such superintelligence would not be just another technological development; it would be the most important invention ever made, and would lead to explosive progress in all scientific and technological fields, as the superintelligence would conduct research with superhuman efficiency. To the extent that ethics is a cognitive (...) pursuit, a superintelligence could also easily surpass humans in the quality of its moral thinking. However, it would be up to the designers of the superintelligence to specify its original motivations. Since the superintelligence may become unstoppably powerful because of its intellectual superiority and the technologies it could develop, it is crucial that it be provided with human-friendly motivations. This paper surveys some of the unique ethical issues in creating superintelligence, and discusses what motivations we ought to give a superintelligence, and introduces some cost-benefit considerations relating to whether the development of superintelligent machines ought to be accelerated or retarded.

I argue that eating meat is morally good and our duty when it is part of a practice that has benefited animals. The existence of domesticated animals depends on the practice of eating them, and the meat-eating practice benefits animals of that kind if they have good lives. The argument is not consequentialist but historical, and it does not apply to nondomesticated animals. I refine the argument and consider objections.

Human enhancement has emerged in recent years as a blossoming topic in applied ethics. With continuing advances in science and technology, people are beginning to realize that some of the basic parameters of the human condition might be changed in the future. One important way in which the human condition could be changed is through the enhancement of basic human capacities. If this becomes feasible within the lifespan of many people alive today, then it is important now to consider the (...) normative questions raised by such prospects. The answers to these questions might not only help us be better prepared when technology catches up with imagination, but they may be relevant to many decisions we make today, such as decisions about how much funding to give to various kinds of research. Enhancement is typically contraposed to therapy. In broad terms, therapy aims to fix something that has gone wrong, by curing specific diseases or injuries, while enhancement interventions aim to improve the state of an organism beyond its normal healthy state. However, the distinction between therapy and enhancement is problematic, for several reasons. First, we may note that the therapy-enhancement dichotomy does not map onto any corresponding dichotomy between standard-contemporary-medicine and medicineas-it-could-be-practised-in-the-future. Standard contemporary medicine includes many practices that do not aim to cure diseases or injuries. It includes, for example, preventive medicine, palliative care, obstetrics, sports medicine, plastic surgery, contraceptive devices, fertility treatments, cosmetic dental procedures, and much else. At the same time, many enhancement interventions occur outside of the medical framework. Office workers enhance their performance by drinking coffee. Make-up and grooming are used to enhance appearance. Exercise, meditation, fish oil, and St John’s Wort are used to enhance mood. Second, it is unclear how to classify interventions that reduce the probability of disease and death.. (shrink)

Stalnaker, 169–199 2006) introduced a combined epistemic-doxastic logic that can formally express a strong concept of belief, a concept of belief as ‘subjective certainty’. In this paper, we provide a topological semantics for belief, in particular, for Stalnaker’s notion of belief defined as ‘epistemic possibility of knowledge’, in terms of the closure of the interior operator on extremally disconnected spaces. This semantics extends the standard topological interpretation of knowledge with a new topological semantics for belief. We prove that the belief (...) logic KD45 is sound and complete with respect to the class of extremally disconnected spaces and we compare our approach to a different topological setting in which belief is interpreted in terms of the derived set operator. We also study belief revision as well as belief dynamics by providing a topological semantics for conditional belief and belief update modalities, respectively. Our setting based on extremally disconnected spaces, however, encounters problems when extended with dynamic updates. We then propose a solution consisting in interpreting belief in a similar way based on hereditarily extremally disconnected spaces, and axiomatize the belief logic of hereditarily extremally disconnected spaces. Finally, we provide a complete axiomatization of the logic of conditional belief and knowledge, as well as a complete axiomatization of the corresponding dynamic logic. (shrink)

I describe and defend the view in a philosophy of mind that I call 'Normative Essentialism', according to which propositional attitudes have normative essences. Those normative essences are 'horizontal' rational requirements, by which I mean the requirement to have certain propositional attitudes given other propositional attitudes. Different propositional attitudes impose different horizontal rational requirements. I distinguish a stronger and a weaker version of this doctrine and argue for the weaker version. I explore the consequences for knowledge of mind, and I (...) then consider objections to the view from mental causation, from empirical psychology, and from animals and small children. (shrink)

Philosophy is a reflective activity. So perhaps it is unsurprising that many philosophers have claimed that reflection plays an important role in shaping and even improving our philosophical thinking. This hypothesis seems plausible given that training in philosophy has correlated with better performance on tests of reflection and reflective reasoning has correlated with demonstrably better judgments in a variety of domains. This article reviews the hypothesized roles of reflection in philosophical thinking as well as the empirical evidence for these roles. (...) This reveals that although there are fairly reliable links between reflection and philosophical judgment among both laypeople and philosophers, the role of reflection in philosophical thinking may nonetheless depend in part on other factors, some of which have yet to be determined. So progress in research on reflection in philosophy may require further innovation in experimental methods and psychometric validation of philosophical measures. (shrink)

Much apprehension has been expressed by philosophers about the method of renormalisation in quantum field theory, as it apparently requires illegitimate procedure of infinite cancellation. This has lead to various speculations, in particular in Teller (1989). We examine Teller's discussion of perturbative renormalisation of quantum fields, and show why it is inadequate. To really approach the matter one needs to understand the ideas and results of the renormalisation group, so we give a simple but comprehensive account of this topic. With (...) this in hand, we explain how renormalisation can and should be understood. One thing that is revealed is that apparently very successful theories such as quantum electro-dynamics cannot be universally true; resolving the tension between success and falsity leads to a picture in which any theory may be viewed as irreducibly phenomenological. We explain how, and argue that the support for this view is tenuous at best. (shrink)

Does human enhancement threaten our dignity as some prominent commentators have asserted? Or could our dignity perhaps be technologically enhanced? After disentangling several different concepts of dignity, this essay focuses on the idea of dignity as a quality, a kind of excellence admitting of degrees and applicable to entities both within and without the human realm. I argue that dignity in this sense interacts with enhancement in complex ways which bring to light some fundamental issues in value theory, and that (...) the effects of any given enhancement must be evaluated in its appropriate empirical context. Yet it is possible that through enhancement we could become better able to appreciate and secure many forms of dignity that are overlooked or missing under current conditions. I also suggest that in a posthuman world, dignity as a quality could grow in importance as an organizing moral/aesthetic idea. (shrink)

Reflectivists consider reflective reasoning crucial for good judgment and action. Anti-reflectivists deny that reflection delivers what reflectivists seek. Alas, the evidence is mixed. So, does reflection confer normative value or not? This paper argues for a middle way: reflection can confer normative value, but its ability to do this is bound by such factors as what we might call epistemic identity: an identity that involves particular beliefs—for example, religious and political identities. We may reflectively defend our identities’ beliefs rather than (...) reflect open-mindedly to adopt whatever beliefs cohere with the best arguments and evidence. This bounded reflectivism is explicated with an algorithmic model of reflection synthesized from philosophy and science that yields testable predictions, psychometric implications, and realistic metaphilosophical suggestions—for example, overcoming motivated reflection may require embracing epistemic identity rather than veiling it (à la Rawls 1971). So bounded reflectivism should be preferred to views offering anything less. (shrink)

The weaver ant, Oecophylla smaragdina Fabricius (Hymenoptera: Formicidae), has long been known as perhaps the first example of human manipulation of a natural predator population to enhance the natural biological control of insect pests. The practice of ant husbandry in Vietnamese citrus orchards and the knowledge associated with the use of weaver ants in the Mekong delta are described. In contrast to other regions of Asia, where weaver ants are noted for their role in the protection of citrus from insect (...) damage, citrus farmers in the Mekong delta explain the benefits of ant husbandry in terms of an improvement in fruit quality, likened to the influence of fertilizers, that occurs in direct response to excretory products deposited by the weaver ants as they patrol the fruit. A series of tests, carried out in 1993–94, rated the external shine, sweetness, juiciness, and overall appeal, as characteristics of fruit quality, for paired comparisons of sweet orange, mandarin, and pummelo fruit that had been grown in the presence of weaver ants or from which ants had been excluded. The tests indicate a strong influence of the presence of the weaver ant on external shine, juiciness, and overall appeal for each of the citrus fruits, but particularly for mandarin. The significance of these results and ant husbandry practices in the Mekong delta are discussed in relation to the development of citrus production in Vietnam. (shrink)

I argue that Hanslick was right to think that music should not be understood in terms of emotion. In particular, it is not essential to music to possess emotions, arouse emotions, express emotions, or represent emotions. All such theories are misguided.

Beauty is an important part of our lives. Ugliness too. It is no surprise then that philosophers since antiquity have been interested in our experiences of and judgments about beauty and ugliness. They have tried to understand the nature of these experiences and judgments, and they have also wanted to know whether these experiences and judgments were legitimate. Both these projects took a sharpened form in the twentieth century, when this part of our lives came under a sustained attack in (...) both European and American intellectual circles. Much of the discourse about beauty since the Eighteenth century had deployed a notion of the ‘aesthetic’, and so that notion in particular came in for criticism. This disdain for the aesthetic may have roots in a broader cultural Puritanism, which fears the connection between the aesthetic and pleasure. Even to suggest, in the recent climate, that an artwork might be good because it is pleasurable, as opposed to cognitively, morally or politically beneficial, is to court derision. The twentieth century has not been kind to the notions of beauty or the aesthetic. Nevertheless, some thinkers — philosophers, as well as others in the study of particular arts — have persisted in thinking about beauty and the aesthetic in a traditional way. In the first part of this essay, I look at the particular rich account of judgments of beauty given to us by Immanuel Kant. The notion of a ‘judgment of taste’ is central to Kant's account and also to virtually everyone working in traditional aesthetics; so I begin by examining Kant's characterisation of the judgment of taste. In the second part, I look at the issues that twentieth century thinkers have raised. I end by drawing on Kant's accout of the judgement of taste to consider whether the notion of the aesthetic is viable. (shrink)

Aesthetic Formalism has fallen on hard times. At best it receives unsympathetic discussion and swift rejection. At worst it is the object of abuse and derision. But I think that there is something to be said for it. In this paper, I shall try to find and secure the truth in formalism. I shall not try to defend formalism against all of the objections to it.1 Instead I shall articulate a moderate formalist view that draws on aesthetic0nonaesthetic determination and Kant’s (...) distinction between free and dependent beauty.

The future of humanity is often viewed as a topic for idle speculation. Yet our beliefs and assumptions on this subject matter shape decisions in both our personal lives and public policy – decisions that have very real and sometimes unfortunate consequences.

This paper sketches an overview of some recent attempts in this direction, and it offers a brief discussion (...) of four families of scenarios for humanity’s future: extinction, recurrent collapse, plateau, and posthumanity.

We describe music in terms of emotion. How should we understand this? Some say that emotion descriptions should be understood literally. Let us call those views “literalist.” By contrast “nonliteralists” deny this and say that such descriptions are typically metaphorical.1 This issue about the linguistic description of music is connected with a central issue about the na- ture of music. That issue is whether there is any essential connection between music and emotion. According to what we can call “emotion theories,” (...) it is essential to music to be somehow related to real emotion. Prominent examples of such theories are these: it is the main function of all or most music to express emotions, to arouse emotions, or to represent emotions. 2 In my view, such theories have little plausibility, and they face a battery of powerful objections. In particular, these theories are objectionable on the grounds that essential features of emotion preclude such essential relations between music and emotion. 3 Yet to argue against various specific emotion theories of music, of which there is a large variety, does not address the reasons that draw people to emotion theories. I think that there are two main reasons. The first is that the most obvious explanation of why we describe music in emotion terms is that emotions, or relations to emotions, are part of what music is. The second reason is introspective, or phenomenological—that much music moves us when we listen to it, so it seems that music generates emotions in us, which we project onto the music when we describe it in emotion terms. In this article, my negative purpose is to dissolve these two reasons. My positive purpose is to argue for a particular nonliteralist view of linguistic descriptions of music in terms of emotion, a..

This paper is about an anti-expertise paradox that arises because of self-referential sentences like: = I do not believe that is true. The first aim is to motivate, develop, and defend a novel view of epistemic rationality according to which there can be genuine rational indeterminacy, i.e., it can be indeterminate which doxastic states an agent is rationally permitted or required to have. The second aim is to show how this view can provide a solution to this paradox while also (...) avoiding the problems that plague its rivals. (shrink)

Much of our private and public ethical discourse occurs in the giving, receiving, or demanding of an apology, yet we suffer deep confusion regarding what an apology actually is. Most of us have never made explicit precisely what we expect from a full apology and therefore apologizing has become a vague and clumsy ritual. Full apologies can be morally and emotionally powerful, but, as with most valuable things, frauds masquerade as the genuine article. These semblances of apologies often deceive and (...) manipulate, and such duplicity is common between lovers, families, litigants, and nations. In response to this, I propose nine elements that an apology must satisfy in order to be considered categorical. I believe we have such a categorical apology in mind when we seek a full apology. The standards for a categorical apology are rigorous and precise, and I hope to disentangle the distinct elements of apologies. A categorical apology is a rare and burdensome act, and under certain circumstances full apologies may not be possible regardless of how badly we may desire them. While the leading social science accounts by Aaron Lazare and Nicolas Tavuchis aptly demonstrate how apologies lubricate reciprocally egoist relationships, such theories ultimately prove unsatisfying because apologies achieve their highest meaning as morally rich acts. Both Tavuchis and Lazare offer merely descriptive accounts when a prescriptive argument seems necessary. No philosopher, however, has ever devoted a monograph to the topic and only a handful of papers on apologies have appeared in philosophy journals. (shrink)

ABSTRACTPolitical rule depends upon public discourse as it requires negotiation and compromise of conflicting interests. Public discourse includes activities that can be described as cause lawyering, lobbying, and rule entrepreneurship. The rule of law supports public discourse through, inter alia, the right to petition. The right to petition requires identification of those engaged in public discourse through petition. This requirement reflects a principle of general application. Solicitors owe an ethical duty to support the rule of law, including the right to (...) petition. Lawyers without a specific duty to uphold the rule of law have ethical duties to maintain the reputation of the legal system and their legal profession. Lawyers, including solicitors, are frequent contributors to public discourse. Lawyers sometimes resist identifying the clients or client groups they represent in public discourse on the ground of the need to protect client confidentiality. This resistance is not ethically well reasoned, a... (shrink)

John Leslie presents a thought experiment to show that chances are sometimes observer-relative in a paradoxical way. The pivotal assumption in his argument – a version of the weak anthropic principle – is the same as the one used to get the disturbing Doomsday argument off the ground.

But not in a paradoxical (...) way. The result can be generalized: At least for a very wide range of cases, the weak anthropic principle does not giverise to paradoxical observer-relative chances. This finding could be taken to give new indirect support to the doomsday argument. (shrink)

Stable logics are modal logics characterized by a class of frames closed under relation preserving images. These logics admit all filtrations. Since many basic modal systems such as K4 and S4 are not stable, we introduce the more general concept of an M-stable logic, where M is an arbitrary normal modal logic that admits some filtration. Of course, M can be chosen to be K4 or S4. We give several characterizations of M-stable logics. We prove that there are continuum many (...) S4-stable logics and continuum many K4-stable logics between K4 and S4. We axiomatize K4-stable and S4-stable logics by means of stable formulas and discuss the connection between S4-stable logics and stable superintuitionistic logics. We conclude the article with many examples (and nonexamples) of stable, K4-stable, and S4-stable logics and provide their axiomatization in terms of stable rules and formulas. (shrink)

Cognitive enhancement takes many and diverse forms. Various methods of cognitive enhancement have implications for the near future. At the same time, these technologies raise a range of ethical issues. For example, they interact with notions of authenticity, the good life, and the role of medicine in our lives. Present and anticipated methods for cognitive enhancement also create challenges for public policy and regulation.

In recent years, the responsibility of corporations has been widely discussed. However, there is no general agreement as regards what CSR is exactly. Due to the indefinite nature of CSR, the term actually embraces several ideas and different contents. A very widespread understanding of CSR defines the subject as (strategic) corporate philanthropy, including operations such as corporate giving, corporate volunteering, corporate foundations, etc. The philanthropic approach to CSR implies that corporations must take responsibility beyond their core business activities. This article (...) argues that a philanthropic approach to CSR is problematic. Moreover, such a conceptualisation strengthens the perception that making Profits is immoral; therefore, it endangers the basis of corporations' license-to-operate in the long run. (shrink)

Although Lakoff and Johnson’s Conceptual Metaphor Theory has been influential across many disciplines, little research has tested the psychological reality of conceptual metaphors using established experimental memory paradigms. Here we employ an episodic memory task based on the Deese-Roediger-McDermott false memory paradigm to explore this possibility. We find that after reading lists of sentences based on underlying conceptual metaphors that participants are more likely to falsely remember the nonpresented conceptual metaphors themselves as well as new sentences consistent with the CM (...) mapping than control items that do not share this mapping. This finding provides experimental support for conceptual metaphors and highlights the utility of using episodic tasks to explore the assumptions of this theory. (shrink)

Intertemporal bargaining theory based on the hyperbolic discounting of expected rewards accounts for how choosing in categories increases self-control, without postulating, as Rachlin does, the additional rewardingness of patterns per se. However, altruism does not seem to be based on self-control, but on the primary rewardingness of vicarious experience. We describe a mechanism that integrates vicarious experience with other goods of limited availability.

Can the contemporary concept of the ‘aesthetic’ be defended? Is it in good shape or is it sick? Should we retain it or dispense with it? The concept of the aesthetic is used to characterize a range of judgements and experiences.

These paradigm cases will anchor the ensuing discussion. Once we have some idea of which (...) judgements are classified as aesthetic judgements, we can go on to ponder what, if anything, they have in common. (shrink)

We give a systematic method of constructing extensions of the Kuznetsov-Gerčiu logic KG without the finite model property (fmp for short), and show that there are continuum many such. We also introduce a new technique of gluing of cyclic intuitionistic descriptive frames and give a new simple proof of Gerčiu’s result [9, 8] that all extensions of the Rieger-Nishimura logic RN have the fmp. Moreover, we show that each extension of RN has the poly-size model property, thus improving on [9]. (...) Furthermore, for each function f: omega -> omega, we construct an extension Lf of KG such that Lf has the fmp, but does not have the f-size model property. We also give a new simple proof of another result of Gerčiu [9] characterizing the only extension of KG that bounds the fmp for extensions of KG. We conclude the paper by proving that RN.KC = RN + (¬p vee ¬¬p) is the only pre-locally tabular extension of KG, introduce the internal depth of an extension L of RN, and show that L is locally tabular if and only if the internal depth of L is finite.

This paper argues, first, that the information problem poses a foundational challenge to mainstream semantics. It proposes, second, to address this problem by drawing on notions from Kit Fine’s essentialist framework.

As a result, the paper proposes to construe semantic theories as theories of semantic requirements, and semantic knowledge as knowledge of such (...) requirements. (shrink)

Thomas Piketty’s Capital and Ideology offers a powerful critique of ideological justifications for inequality in capitalist societies. Does this mean we should reject capitalist institutions altogether? This paper defends some aspects of capitalism by explaining the epistemic function of market economies and their ability to harness capital to meet the needs of the relatively disadvantaged. We support this classical liberal position with reference to empirical research on historical trends in inequality that challenges some of Piketty’s interpretations of the data. Then (...) we discuss the implications of this position in terms of limits on the efficacy of participatory governance within firms and the capacity of the state to levy systematic taxes on wealth.
