This note examines the case of a group of gay men who, having engaged in consensual sexual acts together, became known as the `Bolton Seven' following their conviction in 1998 for offences of buggery and/or gross indecency. More particularly the note scrutinises the implications of the ages of the participants (one of whom, at 17 $\tfrac{1}{2}$ , was unable to give lawful consent to sexual intercourse with a man) in the light of the enactment of Part I of the Sex (...) Offenders Act 1997 which introduces a system of compulsory registration by some convicted and cautioned sex offenders with the police (including men convicted of, or cautioned for, buggery or gross indecency). The note explores the justification for inclusion of these offences within the remit of the1997 Act together with the cultural construction of gay men as predatory and as constituting a risk to younger members of society. It also analyses some of the effects of the registration requirement in terms of it constituting a potential violation of fundamental rights such as equality and respect for private life. This discussion is located particularly within the context of the jurisprudence of the European Court of Human Rights and the introduction of the Human Rights Act 1998 in the U.K. (shrink)

A version of relationism that takes spatiotemporal structures—spatial geometry and a standard of inertia—to supervene on the history of relations between bodies is described and defended. The account is used to explain how the relationist should construe models of Newtonian mechanics in which absolute acceleration manifestly does not supervene on the relations; Ptolemaic and Copernican models for example. The account introduces a new way in which a Lewis-style ‘best system’ might capture regularities in a broadly Humean world; a defence is (...) given against a charge of indeterminism that applies to any such approach to laws.

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)

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)

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.

Recommender systems are artificial intelligence technologies, deployed by online platforms, that model our individual preferences and direct our attention to content we’re likely to engage with. As the digital world has become increasingly saturated with information, we’ve become ever more reliant on these tools to efficiently allocate our attention. And our reliance on algorithmic recommendation may, in turn, reshape us as moral agents. While recommender systems could in principle enhance our moral agency by enabling us to cut through the information (...) saturation of the internet and focus on things that matter, as they’re currently designed and implemented they’re apt to interfere with our ability to attend appropriately to morally relevant factors. In order to analyze the distinctive moral problems algorithmic recommendation poses, we develop a framework for the ethics of attention and an account of judicious attention allocation as a moral skill. We then discuss empirical evidence suggesting that attentional moral skill can be thwarted and undermined in various ways by algorithmic recommendation and related affordances of online platforms, as well as economic and technical considerations that support this concern. Finally, we consider how emerging technologies might overcome the problems we identify. (shrink)

Prior research found correlations between reflection test performance and philosophical tendencies among laypeople. In two large studies (total N = 1299)—one pre-registered—many of these correlations were replicated in a sample that included both laypeople and philosophers. For example, reflection test performance predicted preferring atheism over theism and instrumental harm over harm avoidance on the trolley problem. However, most reflection-philosophy correlations were undetected when controlling for other factors such as numeracy, preferences for open-minded thinking, personality, philosophical training, age, and gender. Nonetheless, (...) some correlations between reflection and philosophical views survived this multivariate analysis and were only partially confounded with either education or self-reported reasoning preferences. Unreflective thinking still predicted believing in God whereas reflective thinking still predicted believing that (a) proper names like ‘Santa’ do not necessarily refer to entities that actually exist and (b) science does reveal the fundamental nature of the world. So some robust relationships between reflection and philosophical tendencies were detected even among philosophers, and yet there was clearly more to the link between reflection and philosophy. To this end, demographic and metaphilosophical hypotheses are considered. (shrink)

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.

A number of commentators (especially French and Redhead, 1988, and Butterfield, 1993) have investigated the status of the principle of the identity of indiscernibles (PII) for bosons and fermions. In this paper I extend that investigation to the full range of quantum particles of any allowed kind of statistics -- `quarticles', that is. I show that for any kind (except bosons and fermions) there are states in which PII is violated by every pair of particles, some pairs and not others, (...) and by no pairs. (shrink)

Most of the debate for and against aesthetic formalism in the twentieth century has been little more than a sequence of assertions, on both sides. But there is one discussion that stands out for its argumentative subtlety and depth, and that is Kendall Walton’s paper ‘Categories of Art’.1 In what follows I shall defend a certain version of formalism against the antiformalist arguments which Walton deploys. I want to show that while Walton’s arguments do indeed create insurmountable difficulties for an (...) extreme version of formalism, he has not shown that a moderate version is problematic or inadequate. (I have no space to address anti-formalist arguments other than Walton’s.2) I shall defend moderate formalism rather than put forward positive considerations in its favour, although some of its attractions will become apparent as a side-effect. I pursue the positive case for moderate formalism elsewhere.3 I. FORMAL PROPERTIES AND FORMALISMS I.1. Walton begins his paper by raising an issue about whether those who make aesthetic judgements should only be concerned with what can be directly perceived in works of art. The issue of formalism has often been described in these terms. But Walton rightly distances himself from setting up a debate in that way. He moves on to take as his target the view that ‘Circumstances connected with a work’s origin ... have no essential bearing on an assessment of its aesthetic nature’ (p. 334). (shrink)

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.

There has been considerable recent philosophical debate over the implications of many particle quantum mechanics for the metaphysics of individuality (cf. Huggett [1997]). In this paper I look at things from a rather different perspective: by investigating the significance of permutation symmetry. I consider how various philosophical positions link up to the physical postulate of the indistinguishability of permuted states-permutation invariance-and how this postulate is used to explain quantum statistics. I offer an explanation of the statistics that relies on the (...) neglected parallel between permutations and covariant spatial transformation. And I explore the parallel, showing that a further kind of symmetry explains why permutations are invariant when spatial symmetries are not. (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. I show that Leslie's thought experiment trades on the sense/reference ambiguity and is fallacious. I then describe a related case where chances are observer-relative in an interesting way. 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)

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)

Many studies find reflective thinking predicts less belief in God or less religiosity — so-called analytic atheism. However, the most widely used tests of reflection confound reflection with ancillary abilities such as numeracy, some studies do not detect analytic atheism in every country, experimentally encouraging reflection makes some non-believers more open to believing in God, and one of the most common sources of online research participants seems to produce lower data quality. So analytic atheism may be less than universal or (...) partially explained by confounding factors. To test this, we developed better measures, controlled for more confounds, and employed more recruitment methods. All four studies detected signs of analytic atheism above and beyond confounds (N > 70,000 people from five of six continental regions). We also discovered analytic apostasy: the better a person performed on reflection tests, the greater their odds of losing their religion since childhood — even when controlling for confounds. Analytic apostasy even seemed to explain analytic atheism: apostates were more reflective than others and analytic atheism was undetected after excluding apostates. Religious conversion was rare and unrelated to reflection, suggesting reflection’s relationships to conversion and deconversion are asymmetric. Detected relationships were usually small, indicating reflective thinking is a reliable albeit marginal predictor of apostasy. (shrink)

Cognitive enhancement may be defined as the amplification or extension of core capacities of the mind through improvement or augmentation of internal or external information processing systems. Cognition refers to the processes an organism uses to organize information. These include acquiring information (perception), selecting (attention), representing (understanding) and retaining (memory) information, and using it to guide behavior (reasoning and coordination of motor outputs). Interventions to improve cognitive function may be directed at any of these core faculties.

This article aims to do two things. The first of these is to introduce the concept of reflexive body techniques into the debate on body modification/maintenance. The value of the concept in relation to this debate, in part, is that it ensures that we conceive of the body as both a subject and an object, modifier and modified, and that we thereby avoid the trap of conceptualizing modification in dualistic (mind/body or body/society) terms. Second, the article seeks to explore the (...) pattern of distribution of practices of modification (conceived as reflexive body techniques) through society and to reflect upon the potential usefulness of multi-dimensional scaling as a tool for doing this. This aim is related to the first aim as it is argued that the concept of reflexive body techniques serves to identify and anchor practices ofmodification in a way that is amenable to both quantitative and qualitative forms of analysis, as well as theoretical investigation.

Here, I put forward a new account of how experience gives rise to the belief that time passes. While there is considerable disagreement amongst metaphysicians as to whether time really does pass, it has struck many as a default, ‘common sense’ way of thinking about the world. A popular way of explaining how such a belief arises is to say that it seems perceptually as though time passes. Here I outline some difficulties for this approach, and propose instead that the (...) belief in time passing is elicited by a particular feature of agentive experience. When we deliberately move our bodies, bring something to mind, or focus our attention, we experience ourselves as the sources of these actions. Sensing oneself as a source, I argue, is a unique type of change experience, one which leads us to a belief that time is passing. (shrink)

In this paper, we argue that Midjourney—a generative AI program that transforms text prompts into images—should be understood not as an agent or a tool, but as a new type of artistic medium. We first examine the view of Midjourney as an agent, considering whether it could be seen as an artist or co-author. This perspective proves unsatisfactory, as Midjourney lacks intentionality and mental states. We then explore the notion of Midjourney as a tool, highlighting its unpredictability and the limited (...) fine-grained control users have over its outputs, which sets it apart from traditional artistic tools. We propose that creating images with Midjourney parallels a gardener's interaction with natura naturans—nature's autonomous generative processes. Similarly, Midjourney acts as machina naturans, where users engage with its dynamic recalcitrance to influence, but not fully control, the creative process. This approach presents Midjourney as an artistic medium shaped by its inherent unpredictability. (shrink)

The authors present climate change and antibiotic resistance as emergent biosocial phenomena—ongoing products of massively multiple interactions among human lifestyles and broader life processes. They argue that response to climate change and antibiotic resistance is often framed by two varieties of biosocial imagination. Anthropocentric imaginations privilege the question of human distinctiveness. Anthropomorphic imaginations privilege the question of whether biosocial processes can be modeled in terms of centers of moral and causal responsibility. Together, these frame the matter of response in terms (...) of deliberate human action. The authors argue that, considered as emergent biosocial phenomena, climate change and antibiotic resistance “diffract” deliberate human action and thus limit the value of this frame by rendering the human/nonhuman and intended/nonintended distinctions that are crucial to its practical operation locally irrelevant. Alternative biosocial imaginations currently developing around climate change and antibiotic resistance that allow for “diffraction” and therefore frame response differently are considered. (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)

Abstract: This article addresses a number of difficulties and complications in the standard formulations of motivational internalism, and considers what besires might be in the light of those difficulties and complications. Two notions of besire are then distinguished, before considering how different kinds of motivational internalism and different conceptions of besire fare against the significant argument that we may be indifferent to the demands of morality without irrationality.

I develop a broadly reliabilist theory of non-ideal epistemic rationality and argue that if it is correct we should reject the recently popular idea that the standards of non-ideal epistemic rationality are mere social conventions.

Rational analysis (Anderson 1990, 1991a) is an empiricalprogram of attempting to explain why the cognitive system isadaptive, with respect to its goals and the structure of itsenvironment. We argue that rational analysis has two importantimplications for philosophical debate concerning rationality. First,rational analysis provides a model for the relationship betweenformal principles of rationality (such as probability or decisiontheory) and everyday rationality, in the sense of successfulthought and action in daily life. Second, applying the program ofrational analysis to research on human reasoning (...) leads to a radicalreinterpretation of empirical results which are typically viewed asdemonstrating human irrationality.

We prove that the modal logic of a crowded locally compact generalized ordered space is$\textsf {S4}$. This provides a version of the McKinsey–Tarski theorem for generalized ordered spaces. We then utilize this theorem to axiomatize the modal logic of an arbitrary locally compact generalized ordered space.

In this paper, we explore and describe what is needed to allow connected and automated vehicles to break traffic rules in order to minimise road safety risk and to operate with appropriate transparency. Reviewing current traffic rules with particular reference to two driving situations, we illustrate why current traffic rules are not suitable for CAVs and why making new traffic rules specifically for CAVs would be inappropriate. In defining an alternative approach to achieving safe CAV driving behaviours, we describe the (...) use of ethical goal functions as part of hybrid AI systems, suggesting that functions should be defined by governmental bodies with input from citizens and stakeholders. Ethical goal functions for CAVs would enable developers to optimise driving behaviours for safety under conditions of uncertainty whilst allowing for differentiation of products according to brand values. Such functions can differ between regions according to preferences for safety behaviours within that region and can be updated over time, responding to continual socio-technological feedback loops. We conclude that defining ethical goal functions is an urgent and necessary step from governmental bodies to enable the safe and transparent operation of CAVs and accelerate the reduction in road casualties they promise to achieve.

This paper is about an anti-expertise paradox that arises because of self-referential sentences like: = I do not believe that is true.

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)

This commentary focuses on three issues raised by Gigerenzer, Todd, and the ABC Research Group (1999). First, I stress the need for further experimental evidence to determine which heuristics people use in cognitive judgment tasks. Second, I question the scope of cognitive models based on simple heuristics, arguing that many aspects of cognition are too sophisticated to be modeled in this way. Third, I note the complementary role that rational explanation can play to Gigenerenzer et al.'s “ecological” analysis of why (...) heuristics succeed. (shrink)

In this article, I argue that God is authoritative over us because he is our divine, causal parent. As our causal parent, God has duties to relate to us, but he can only fulfill those duties if he has the practical authority to give us commands aimed at our sanctification. From ought-implies-can reasoning, I conclude that God has that authority. After I make this argument, I show how the view has significant advantages over extant arguments for divine authority and can (...) help solve other significant problems in philosophy of religion.

Three experiments investigated the contrasting predictions of the evolutionary and decision-theoretic approaches to deontic reasoning. Two experiments embedded a hazard management (HM) rule in a social contract scenario that should lead to competition between innate modules. A 3rd experiment used a pure HM task. Threatening material was also introduced into the antecedent, p, of a deontic rule, if p then must q. According to the evolutionary approach, more HM responses (Cosmides & Tooby, 2000) are predicted when p is threatening, whereas (...) decision theory predicts fewer. All 3 experiments were consistent with decision theory. Other theories are discussed, and it is concluded that they cannot account for the behavior observed in these experiments. (shrink)

If it does not, then I can be taken to be providing a theory of those works that have aesthetic aspirations. To have given (...) an account of their nature would be success enough. (shrink)

This paper has been extracted from a book manuscript that attempts to interpret Gandhi’s ethics of nonviolence ahimsa) in terms of virtue theory. The first section addresses the issue of virtue theory’s relationship to consequentialism and concludes that there is no way to avoid the fact that the virtues developed because of their consequences. Therefore, I will join Gandhi’s virtue ethics with P. J. Ivanhoe’s character consequentialism. Particularly significant in distinguishing utilitarianism from virtue theory is the relationship of means to (...) ends. Character consequentialism will insist that moral ends are always internally related to the virtues as means. In the second section I will explicate the distinction between enabling and substantive virtues, discuss the enabling virtues of self-control, patience, and courage, and conclude that the virtue of nonviolence forms an alliance with these enabling virtues.

Both critics and advocates of evidential arguments from evil often assume that theistic belief is not compatible with gratuitous evil. It is often assumed, in other words, that an omniscient, omnipotent, perfectly good being would not permit an evil unless he had a morally sufficient reason to permit it.

The aim of this paper is to outline and then assess (...) van Inwagen’s attempt to reconcile theism with gratuitous evil. (shrink)

Van Gelder's specification of the dynamical hypothesis does not improve on previous notions. All three key attributes of dynamical systems apply to Turing machines and are hence too general. However, when a more restricted definition of a dynamical system is adopted, it becomes clear that the dynamical hypothesis is too underspecified to constitute an interesting cognitive claim.

In his paper "Supervenience Revisisted", Simon Blackburn redeployed his novel modal argument against moral realism as an argument against Donald Davidson's position of 'anomalous monism' in the philosophy of mind (Blackburn 1985).' I shall assess this redeployment. In the first part of this paper, I shall lay out Blackburn's argument. In the second and longer part I shall examine Davidson's denial of psychophysical laws in the light of this argument.

Over the past few years, a new paradigm for thinking about humankind's future has begun to take shape among some leading computer scientists, neuroscientists, nanotechnologists and researchers at the forefront of technological development. The new paradigm rejects a crucial assumption that is implicit in both traditional futurology and practically all of today's political thinking. This is the assumption that the "human condition" is at root a constant. Present-day processes can be fine-tuned; wealth can be increased and redistributed; tools can be (...) developed and refined; culture can change, sometimes drastically; but human nature itself is not up for grabs.
