We are living through an era of increased robotisation. Some authors have already begun to explore the impact of this robotisation on legal rules and practice. In doing so, many highlight potential liability gaps that might arise through robot misbehaviour. Although these gaps are interesting and socially significant, they do not exhaust the possible gaps that might be created by increased robotisation. In this article, I make the case for one of those alternative gaps: the retribution gap. This gap arises (...) from a mismatch between the human desire for retribution and the absence of appropriate subjects of retributive blame. I argue for the potential existence of this gap in an era of increased robotisation; suggest that it is much harder to plug this gap than it is to plug those thus far explored in the literature; and then highlight three important social implications of this gap.

If a robot sends a deceptive signal to a human user, is this always and everywhere an unethical act, or might it sometimes be ethically desirable? Building upon previous work in robot ethics, this article tries to clarify and refine our understanding of the ethics of robotic deception. It does so by making three arguments. First, it argues that we need to distinguish between three main forms of robotic deception (external state deception; superficial state deception; and hidden state deception) in (...) order to think clearly about its ethics. Second, it argues that the second type of deception – superficial state deception – is not best thought of as a form of deception, even though it is frequently criticised as such. And third, it argues that the third type of deception is best understood as a form of betrayal because doing so captures the unique ethical harm to which it gives rise, and justifies special ethical protections against its use.

Personal AI assistants are now nearly ubiquitous. Every leading smartphone operating system comes with a personal AI assistant that promises to help you with basic cognitive tasks: searching, planning, messaging, scheduling and so on. Usage of such devices is effectively a form of algorithmic outsourcing: getting a smart algorithm to do something on your behalf. Many have expressed concerns about this algorithmic outsourcing. They claim that it is dehumanising, leads to cognitive degeneration, and robs us of our freedom and autonomy. (...) Some people have a more subtle view, arguing that it is problematic in those cases where its use may degrade important interpersonal virtues. In this article, I assess these objections to the use of AI assistants. I will argue that the ethics of their use is complex. There are no quick fixes or knockdown objections to the practice, but there are some legitimate concerns. By carefully analysing and evaluating the objections that have been lodged to date, we can begin to articulate an ethics of personal AI use that navigates those concerns. In the process, we can locate some paradoxes in our thinking about outsourcing and technological dependence, and we can think more clearly about what it means to live a good life in the age of smart machines.

Friendship is an important part of the good life. While many roboticists are eager to create friend-like robots, many philosophers and ethicists are concerned. They argue that robots cannot really be our friends. Robots can only fake the emotional and behavioural cues we associate with friendship. Consequently, we should resist the drive to create robot friends. In this article, I argue that the philosophical critics are wrong. Using the classic virtue-ideal of friendship, I argue that robots can plausibly be considered (...) our virtue friends - that to do so is philosophically reasonable. Furthermore, I argue that even if you do not think that robots can be our virtue friends, they can fulfil other important friendship roles, and can complement and enhance the virtue friendships between human beings.

Soon there will be sex robots. The creation of such devices raises a host of social, legal and ethical questions. In this article, I focus in on one of them. What if these sex robots are deliberately designed and used to replicate acts of rape and child sexual abuse? Should the creation and use of such robots be criminalised, even if no person is harmed by the acts performed? I offer an argument for thinking that they should be. The argument (...) consists of two premises. The first claims that it can be a proper object of the criminal law to regulate wrongful conduct with no extrinsically harmful effects on others. The second claims that the use of robots that replicate acts of rape and child sexual abuse would be wrongful, even if such usage had no extrinsically harmful effects on others. I defend both premises of this argument and consider its implications for the criminal law. I do not offer a conclusive argument for criminalisation, nor would I wish to be interpreted as doing so; instead, I offer a tentative argument and a framework for future debate. This framework may also lead one to question the proposed rationales for criminalisation. (shrink)

The principle of universal instantiation plays a pivotal role both in the derivation of intensional paradoxes such as Prior’s paradox and Kaplan’s paradox and the debate between necessitism and contingentism. We outline a distinctively free logical approach to the intensional paradoxes and note how the free logical outlook allows one to distinguish two different, though allied themes in higher-order necessitism. We examine the costs of this solution and compare it with the more familiar ramificationist approaches to higher-order logic. Our assessment (...) of both approaches is largely pessimistic, and we remain reluctantly inclined to take Prior’s and Kaplan’s derivations at face value. (shrink)

The analysis of desire ascriptions has been a central topic of research for philosophers of language and mind. This work has mostly focused on providing a theory of want reports, that is, sentences of the form ‘S wants p’. In this paper, we turn from want reports to a closely related but relatively understudied construction, namely hope reports, that is, sentences of the form ‘S hopes p’. We present two contrasts involving hope reports and show that existing approaches to desire (...) fail to explain these contrasts. We then develop a novel account that combines some of the central insights in the literature. We argue that our theory provides an elegant account of our contrasts and yields a promising analysis of hoping. (shrink)

Philosophers have often noted a contrast between practical and theoretical reasons when it comes to cases involving equally balanced reasons. When there are strong practical reasons for A-ing, and equally strong practical reasons for some incompatible option, B-ing, the agent is permitted to make an arbitrary choice between them, having sufficient reason to A and sufficient reason to B. But when there is strong evidence for P and equally strong evidence for ~ P, one isn’t permitted to simply believe one (...) or the other. Instead, one must withhold belief, neither believing that P nor believing that ~ P. This paper examines what explains this contrast, focusing in particular on a proposal recently developed by Mark Schroeder across several papers. Schroeder aims to explain the contrast by an appeal to non-evidential, epistemic reasons against belief. But, I argue, it’s not clear exactly what those reasons are, nor how those reasons are to be weighed against evidential reasons. Despite these challenges, I argue that there are grounds for optimism that the contrast can be explained within the broad framework Schroeder provides, and I aim to provide resources to meet the aforementioned challenges.

In July 2014, the roboticist Ronald Arkin suggested that child sex robots could be used to treat those with paedophilic predilections in the same way that methadone is used to treat heroin addicts. Taking this onboard, it would seem that there is reason to experiment with the regulation of this technology. But most people seem to disagree with this idea, with legal authorities in both the UK and US taking steps to outlaw such devices. In this paper, I subject these (...) different regulatory attitudes to critical scrutiny. In doing so, I make three main contributions to the debate. First, I present a framework for thinking about the regulatory options that we confront when dealing with child sex robots. Second, I argue that there is a prima facie case for restrictive regulation, but that this is contingent on whether Arkin’s hypothesis has a reasonable prospect of being successfully tested. Third, I argue that Arkin’s hypothesis probably does not have a reasonable prospect of being successfully tested. Consequently, we should proceed with utmost caution when it comes to this technology.

Eleanor Knox has argued that our concept of spacetime applies to whichever structure plays a certain functional role in the laws (the role of determining local inertial structure). I raise two complications for this approach. First, our spacetime concept seems to have the structure of a cluster concept, which means that Knox's inertial criteria for spacetime cannot succeed with complete generality. Second, the notion of metaphysical fundamentality may feature in the spacetime concept, in which case spacetime functionalism may be uninformative (...) in the absence of answers to fundamental metaphysical questions like the substantivalist/relationist debate.

We live in a world in which ‘smart’ algorithmic tools are regularly used to structure and control our choice environments. They do so by affecting the options with which we are presented and the choices that we are encouraged or able to make. Many of us make use of these tools in our daily lives, using them to solve personal problems and fulfill goals and ambitions. What consequences does this have for individual autonomy and how should our legal and regulatory (...) systems respond? This chapter defends three claims by way of response. First, it argues that autonomy is indeed under threat in some new and interesting ways. Second, it evaluates and disputes the claim that we shouldn’t overestimate these new threats because the technology is just an old wolf in a new sheep’s clothing. Third, and finally, it looks at responses to these threats at both the individual and societal level and argues that although we shouldn’t encourage an attitude of ‘helplessness’ among the users of algorithmic tools there is an important role for legal and regulatory responses to these threats that go beyond what are currently on offer.

In the present article we attempt to show that Aristotle's syllogistic is an underlying logiC which includes a natural deductive system and that it isn't an axiomatic theory as had previously been thought. We construct a mathematical model which reflects certain structural aspects of Aristotle's logic. We examine the relation of the model to the system of logic envisaged in scattered parts of Prior and Posterior Analytics. Our interpretation restores Aristotle's reputation as a logician of consummate imagination and skill. Several (...) attributions of shortcomings and logical errors to Aristotle are shown to be without merit. Aristotle's logic is found to be self-sufficient in several senses: his theory of deduction is logically sound in every detail. (His indirect deductions have been criticized, but incorrectly on our account.) Aristotle's logic presupposes no other logical concepts, not even those of propositional logic. The Aristotelian system is seen to be complete in the sense that every valid argument expressible in his system admits of a deduction within his deductive system: every semantically valid argument is deducible.

Sex is an important part of human life. It is a source of pleasure and intimacy, and is integral to many people’s self-identity. This chapter examines the opportunities and challenges posed by the use of AI in how humans express and enact their sexualities. It does so by focusing on three main issues. First, it considers the idea of digisexuality, which according to McArthur and Twist (2017) is the label that should be applied to those ‘whose primary sexual identity comes (...) through the use of technology’, particularly through the use of robotics and AI. While agreeing that this phenomenon is worthy of greater scrutiny, the chapter questions whether it is necessary or socially desirable to see this as a new form of sexual identity. Second, it looks at the role that AI can play in facilitating human-to-human sexual contact, focusing in particular on the use of self-tracking and predictive analytics in optimising sexual and intimate behaviour. There are already a number of apps and services that promise to use AI to do this, but they pose a range of ethical risks that need to be addressed at both an individual and societal level. Finally, it considers the idea that a sophisticated form of AI could be an object of love. Can we be truly intimate with something that has been ‘programmed’ to love us? Contrary to the widely-held view, this chapter argues that this is indeed possible. (shrink)

The chapter introduces the edited collection Robot Sex: Social and Ethical Implications. It proposes a definition of the term 'sex robot' and examines some current prototype models. It also considers the three main ethical questions one can ask about sex robots: (i) do they benefit/harm the user? (ii) do they benefit/harm society? or (iii) do they benefit/harm the robot?

Humans have long wondered whether they can survive the death of their physical bodies. Some people now look to technology as a means by which this might occur, using terms such 'whole brain emulation', 'mind uploading', and 'substrate independent minds' to describe a set of hypothetical procedures for transferring or emulating the functioning of a human mind on a synthetic substrate. There has been much debate about the philosophical implications of such procedures for personal survival. Most participants to that debate (...) assume that the continuation of identity is an objective fact that can be revealed by scientific enquiry or rational debate. We bring into this debate a perspective that has so far been neglected: that personal identities are in large part social constructs. Consequently, to enable a particular identity to survive the transference process, it is not sufficient to settle age-old philosophical questions about the nature of identity. It is also necessary to maintain certain networks of interaction between the synthetic person and its social environment, and sustain a collective belief in the persistence of identity. We defend this position by using the example of the Dalai Lama in Tibetan Buddhist tradition and identify technological procedures that could increase the credibility of personal continuity between biological and artificial substrates.

This is an English translation of Waldenfels' German essay: Equality and inequality are basic elements of law, justice and politics. Equality integrates each of us into a common sphere by distributing rights, duties and chances among us. Equality turns into mere indifference as far as we get overintegrated into social orders. When differences are fading away experience loses its relief and individuals lose their face. Our critical reflections start from the inevitable paradox of making equal what is not equal. In (...) various ways they refer to Nietzsche’s concept of order, to Marx’s analysis of money, to Lévinas’s ethics of the Other, and to novelists like Dostoevsky and Musil. Our critique turns against two extremes, on the one hand against any sort of normalism fixed on functioning orders, on the other hand against any sort of anomalism dreaming of mere events and permanent ruptures. Responsive phenomenology shows how we are confronted with extraordinary events. Those deviate from the ordinary and transgress its borders, without leaving the normality of our everyday world behind. The process of equalizing moves between the ordinary and the extraordinary. What makes the difference and resists mere indifference are creative responses which are to be invented again and again.

An advanced artificial intelligence could pose a significant existential risk to humanity. Several research institutes have been set-up to address those risks. And there is an increasing number of academic publications analysing and evaluating their seriousness. Nick Bostrom’s superintelligence: paths, dangers, strategies represents the apotheosis of this trend. In this article, I argue that in defending the credibility of AI risk, Bostrom makes an epistemic move that is analogous to one made by so-called sceptical theists in the debate about the (...) existence of God. And while this analogy is interesting in its own right, what is more interesting are its potential implications. It has been repeatedly argued that sceptical theism has devastating effects on our beliefs and practices. Could it be that AI-doomsaying has similar effects? I argue that it could. Specifically, and somewhat paradoxically, I argue that it could amount to either a reductio of the doomsayers position, or an important and additional reason to join their cause. I use this paradox to suggest that the modal standards for argument in the superintelligence debate need to be addressed. (shrink)

This chapter provides a general overview and introduction to the law and ethics of virtual sexual assault. It offers a definition of the phenomenon and argues that there are six interesting types. It then asks and answers three questions: (i) should we criminalise virtual sexual assault? (ii) can you be held responsible for virtual sexual assault? and (iii) are there issues with 'consent' to virtual sexual activity that might make it difficult to prosecute or punish virtual sexual assault?

What a person is doing often depends on that person’s thought about what they are doing, or about the wider circumstances of their action. For example, whether my killing is murder or manslaughter depends, in part, on whether I understand that what I am doing is killing you, and on whether I understand that my killing is unjustified. Similarly, if I know that the backpack I am taking is yours, then my taking it may be an act of theft; but (...) it is not theft if I simply mistook your backpack for my own. And if I don’t know that in signing a document I’m promising to do some thing, then in signing it I’m not promising to do this at all. -/- According to Elizabeth Anscombe, a central task of philosophical psychology is to articulate this dependency of action on thought. And in a range of papers published during the 1960s, Anscombe sought to elucidate various aspects of this dependency. In this paper we give a systematic overview of how Anscombe understands this dependency, and in the process reveal the conceptual framework underlying Anscombe’s thinking about perception, desire, intention, voluntariness, responsibility, guilt, and sin.

The outlines of a novel, fully naturalistic theory of perception are provided, that can explain perception of an object X by organism Z in terms of reflexive causality. On the reflexive view proposed, organism Z perceives object or property X just in case X causes Z to acquire causal dispositions reflexively directed back upon X itself. This broadly functionalist theory is potentially capable of explaining both perceptual representation and perceptual content in purely causal terms, making no use of informational concepts. (...) However, such a reflexive, naturalistic causal theory must compete with well entrenched, supposedly equally naturalistic theories of perception that are based on some concept of information, so the paper also includes some basic logical, naturalistic and explanatory criticisms of such informational views.

Skeptical theism (ST) may undercut the key inference in the evidential argument from evil, but it does so at a cost. If ST is true, then we lose our ability to assess the all things considered (ATC) value of natural events and states of affairs. And if we lose that ability, a whole slew of undesirable consequences follow. So goes a common consequential critique of ST. In a recent article, Anderson has argued that this consequential critique is flawed. Anderson claims (...) that ST only has the consequence that we lack epistemic access to potentially God-justifying reasons for permitting a prima facie “bad” (or “evil”) event. But this is very different from lacking epistemic access to the ATC value of such events. God could have an (unknowable) reason for not intervening to prevent E and yet E could still be (knowably) ATC-bad. Ingenious though it is, this article argues that Anderson’s attempted defence of ST is flawed. This is for two reasons. First, and most importantly, the consequential critique does not rely on the questionable assumption he identifies. Indeed, the argument can be made quite easily by relying purely on Anderson’s distinction between God-justifying reasons for permitting E and the ATC value of E. And second, Anderson’s defence of his position, if correct, would serve to undermine the foundations of ST. (shrink)

Bayne and Nagasawa have argued that the properties traditionally attributed to God provide an insufficient grounding for the obligation to worship God. They do so partly because the same properties, when possessed in lesser quantities by human beings, do not give rise to similar obligations. In a recent paper, Jeremy Gwiazda challenges this line of argument. He does so because it neglects the possible existence of a threshold obligation to worship, i.e. an obligation that only kicks in when the value (...) of a parameter has crossed a certain threshold. This article argues that there is a serious flaw in Gwiazda’s proposal. Although thresholds may play an important part in how we think about our obligations, their function is distinct from that envisaged by Gwiazda. To be precise, this article argues that thresholds are only relevant to obligations to the extent that they transform a pre-existing imperfect obligation or act of supererogation into a perfect obligation. Since it is not clear that there is an imperfect obligation to worship any being, and indeed since on a certain conception of moral agency it is highly unlikely that there could be, the search for a rational basis for the obligation to worship must continue.

Is sex work (specifically, prostitution) vulnerable to technological unemployment? Several authors have argued that it is. They claim that the advent of sophisticated sexual robots will lead to the displacement of human prostitutes, just as, say, the advent of sophisticated manufacturing robots have displaced many traditional forms of factory labour. But are they right? In this article, I critically assess the argument that has been made in favour of this displacement hypothesis. Although I grant the argument a degree of credibility, (...) I argue that the opposing hypothesis -- that prostitution will be resilient to technological unemployment -- is also worth considering. Indeed, I argue that increasing levels of technological unemployment in other fields may well drive more people into the sex work industry. Furthermore, I argue that no matter which hypothesis you prefer -- displacement or resilience -- you can make a good argument for the necessity of a basic income guarantee, either as an obvious way to correct for the precarity of sex work, or as a way to disincentivise those who may be drawn to prostitution.

The field of machine perception is based on standard informational and computational approaches to perception. But naturalistic informational theories are widely regarded as being inadequate, while purely syntactic computational approaches give no account of perceptual content. Thus there is a significant need for a novel, purely naturalistic perceptual theory not based on informational or computational concepts, which could provide a new paradigm for mechanistic perception. Now specifically evolutionary naturalistic approaches to perception have been—perhaps surprisingly—almost completely neglected for this purpose. Arguably (...) perceptual mechanisms enhance evolutionary fitness by facilitating sensorily mediated causal interactions between an organism Z and items X in its environment. A ‘reflexive’ theory of perception of this kind is outlined, according to which an organism Z perceives an item X just in case X causes a sensory organ zi of Z to cause Z to acquire a disposition toward the very same item X that caused the perception. The rest of the paper shows how an intuitively plausible account of mechanistic perception can be developed and defended in terms of the reflexive theory. Also, a compatibilist option is provided for those who wish to preserve a distinct informational concept of perception. (shrink)

RÉSUMÉ : Dans son récent recueil d’articles Language, Truth and History, Donald Davidson semble pencher en faveur d’une philosophie du langage mettant l’accent sur la notion de l’intention communicative du sujet parlant; en quoi il se rapproche du point de vue de Paul Grice. Si cela est juste, la pensée de Davidson se serait dégagée de l’approche sémantique formelle qu’il soutenait dans ses Inquiries into Truth and Interpretation. Dans cet article, je soutiens que, bien qu’il y ait beaucoup de similitudes (...) entre ces deux penseurs, Davidson n’a pas abandonné ses précédentes vues sur le langage. (shrink)

In Languages of Art, Nelson Goodman presents a general theory of symbolic notation. However, I show that his theory could not adequately explain possible cases of natural language notational uses, and argue that this outcome undermines, not only Goodman's own theory, but any broadly type versus token based account of notational structure.Given this failure, an alternative representational theory is proposed, in which different visual or perceptual aspects of a given physical inscription each represent a different letter, word, or other notational (...) item. Such a view is strongly supported by the completely conventional relation between inscriptions and notation, as shown by encryption techniques etc. (shrink)

A dilemma exists when a doctor is faced with a child or young person who refuses medically indicated treatment. The Gillick case has been interpreted by many to mean that a child of sufficient age and intelligence could validly consent or refuse consent to treatment. Recent decisions of the Court of Appeal on a child's refusal of medical treatment have clouded the issue and undermined the spirit of the Gillick decision and the Children Act 1989. It is now the case (...) that a child patient whose competence is in doubt will be found rational if he or she accepts the proposal to treat but may be found incompetent if he or she disagrees. Practitioners are alerted to the anomalies now exhibited by the law on the issue of children's consent and refusal. The impact of the decisions from the perspectives of medicine, ethics, and the law are examined. Practitioners should review each case of child care carefully and in cases of doubt seek legal advice.

Patrick Grim advances arguments meant to show that the doctrine of divine omniscience—the classical doctrine according to which God knows all truths—is false. In particular, we here have in mind to focus on two such arguments: the set theoretic argument and the semantic argument. These arguments due to Grim run parallel to, respectively, familiar paradoxes in set theory and naive truth theory. It is beyond the purview of this article to adjudicate whether or not these are successful arguments against the (...) classical doctrine of omniscience. What we are here interested in is a way in which these arguments can be generalized. In particular, we show how generalizations of those arguments can target, explicitly, alternatives to the classical doctrine of omniscience, including what we here call 'restricted omniscience' and 'open future open theism'. As a corollary, considerations of Grim-style arguments do not support these alternatives to the classical doctrine of omniscience over the classical doctrine. We conclude that what is paradoxical is not the classical doctrine of omniscience just as such; rather, what is paradoxical is a core commitment shared by the classical doctrine and its more modest alternatives, namely, the thesis that God is a perfectly logical reasoner.

Can human life have value in a world in which humans are rendered obsolete by technological advances? This article answers this question by developing an extended analysis of the axiological impact of human obsolescence. In doing so, it makes four main arguments. First, it argues that human obsolescence is a complex phenomenon that can take on at least four distinct forms. Second, it argues that one of these forms of obsolescence is not a coherent concept and hence not a plausible (...) threat to human well-being. Third, it argues that existing fears of technologically-induced human obsolescence are less compelling than they first appear. Fourth, it argues that there are two reasons for embracing a world of widespread, technologically-induced human obsolescence. (shrink)

Ted Sider has shown that my indeterminism argument for comparativist theories of quantity also applies to Mundy's absolutist theory. This is because Mundy's theory posits only "pure" relations, i.e. relations between values of the same quantity (between masses and other masses, or distances and other distances). It is straightforward to solve the problem by positing additional mixed relations.

A Inseparabilidade entre Lógica e a Ética. Philósophos. 18 (2013) 245–259. Portuguese translation by Décio Krause and Pedro Merlussi: The Inseparability of Logic and Ethics, Free Inquiry, Spring 1989, 37–40. This essay takes logic and ethics in broad senses: logic as the science of evidence; ethics as the science of justice. One of its main conclusions is that neither science can be fruitfully pursued without the virtues fostered by the other: logic is pointless without fairness and compassion; ethics is pointless (...) without rigor and objectivity. The logician’s advice to be dispassionate is in resonance and harmony with the ethicist’s advice to be compassionate. (shrink)

Representationalists who hold that phenomenal character can be explained in terms of representational content currently cannot explain counter-examples that involve indeterminate perceptual content, such as in the case of objects seen blurrily by someone with poor eyesight, or objects seen vaguely in misty conditions. But this problem can be resolved via provision of a more sophisticated double content (DC) view, according to which the representational content of perception is structured in two nested levels. I start by outlining the DC view (...) via consideration of four closely related cases of perceptual imprecision. Then, after a demonstration that the DC view can also explain imprecise photographic content, inadequacies in the more standard single content (SC) view are demonstrated. The results are then generalized so as to apply to the content of any kinds of non-conventional representation. The paper continues with evidence that a DC account provides a moderate rather than extreme realist account of perception, and it concludes with an initial analysis of the failure of nomic covariance accounts of information in indeterminacy cases.

This entry considers the question of whether rationality is normative; that is, the question of whether one always ought (or, more weakly, has a reason) to be rational. It first distinguishes substantive from structural rationality, noting how structural rationality presents a more serious challenge to the thesis that rationality is normative. It then considers the plausibility of skepticism about structural rationality, and notes some problems facing such skepticism. However, if we are not skeptics about structural requirements, we face the task (...) of formulating those requirements. But both narrow-scope and wide-scope formulations seem incompatible with the idea that we always ought to be rational. This suggests that we have good reason to think that rationality is not strongly normative. (shrink)

The debate over the merits of originalism has advanced considerably in recent years, both in terms of its intellectual sophistication and its practical significance. In the process, some prominent originalists—Lawrence Solum and Jeffrey Goldsworthy being the two discussed here—have been at pains to separate out the linguistic and normative components of the theory. For these authors, while it is true that judges and other legal decision-makers ought to be originalists, it is also true that the communicated content of the constitution (...) is its original meaning. That is to say: the meaning is what it is, not what it should be. Accordingly, there is no sense in which the communicated content of the constitution is determined by reference to moral desiderata; linguistic desiderata do all the work. In this article, I beg to differ. In advancing their arguments for linguistic originalism, both authors rely upon the notion of successful communications conditions. In doing so they implicitly open up the door for moral desiderata to play a role in determining the original communicated content. This undercuts their claim and changes considerably the dialectical role of linguistic originalism in the debate over constitutional interpretation. (shrink)

Are universities justified in trying to regulate student use of cognitive enhancing drugs? In this article I argue that they can be, but that the most appropriate kind of regulatory intervention is likely to be voluntary in nature. To be precise, I argue that universities could justifiably adopt a commitment contract system of regulation wherein students are encouraged to voluntarily commit to not using cognitive enhancing drugs. If they are found to breach that commitment, they should be penalized by, for (...) example, forfeiting a number of marks on their assessments. To defend this model of regulation, I adopt a recently-proposed evaluative framework for determining the appropriateness of enhancement in specific domains of activity, and I focus on particular existing types of cognitive enhancement drugs, not hypothetical or potential forms. In this way, my argument is tailored to the specific features of university education, and common patterns of usage among students. It is not concerned with the general ethical propriety of using cognitive enhancing drugs. (shrink)

In "A Restriction for Pictures and Some Consequences for a Theory of Depiction", Journal of Aesthetics and Art Criticism 61, 4 (2003): 381-394, Michael Newall defended a resemblance view of depiction.

But I show that there are many (...) problems with his approach, so that overall it is no more successful than more standard resemblance views of depiction. (shrink)

There is some intuitive plausibility to the idea that composers create musical works by indicating sonic types in a historical context. But the idea is technically indefensible as it stands, requiring a thorough representational reform that also eliminates the type-theoretic commitments of current versions. On the reformed account, musical 'indication' is an operation of high level representational interpretation of concrete sounds, that can both explain the creativity of composers, and the often successful interpretations of their listeners. This approach also bypasses (...) contentious issues regarding the status of both indicated and 'initiated' types, as extensively discussed in the BJA. (shrink)

The lie detector test has long been treated with suspicion by the law. Recently, several authors have called this suspicion into question. They argue that the lie detector test may have considerable forensic benefits, particularly if we move past the classic, false-positive prone, autonomic nervous system-based (ANS-based) control question test, to the more reliable, brain-based, concealed information test. These authors typically rely on a “comparative advantage” argument to make their case. According to this argument, we should not be so suspicious (...) of lie detection evidence if it has comparative advantages over the epistemic methods currently utilised by the legal system. In this article, I add to this growing support by making a novel comparative advantage argument in favour of brain-based lie detection evidence. The argument focuses on the P300 concealed information test (P300 CIT), which has several unique properties, and on the effect it may have on pre-trial bargaining in criminal cases rather than in-court evidence. The thesis is that P300 CIT could allow for innocent defendants to credibly signal their innocence to investigators and prosecutors during pre-trial bargaining more effectively than current proposed methods for doing the same thing. I defend this argument from a number of objections, and suggest that it opens up an interesting avenue in the ongoing debate about the merits of this technology. Although the argument is presented with the criminal law in mind, it could form part of a more general cumulative case in favour of this technology. (shrink)

Memory Detection Tests (MDTs) are a general class of psychophysiological tests that can be used to determine whether someone remembers a particular fact or datum. The P300 MDT is a type of MDT that relies on a presumed correlation between the presence of a detectable neural signal (the P300 “brainwave”) in a test subject, and the recognition of those facts in the subject’s mind. As such, the P300 MDT belongs to a class of brain-based forensic technologies which have proved popular (...) and controversial in recent years. With such tests increasingly being proffered for use in the courtroom — to either support or call into question testimony — it would behoove the legal system to have some systematic framework for ensuring that they are used responsibly. In this paper, I defend one such framework for ensuring that this is the case: the legitimacy enhancing test. According to this test, it is appropriate to make use of technologies such as the P300 MDT whenever doing so would (probably) enhance the legitimacy of the trial. I argue that this test addresses tensions between scientific and legal norms of evidence, and exhibits a number of additional virtues including unification, simplicity and flexibility. Although the test is defended by considering the example of the P300 MDT, its significance is much broader than that. If it has the virtues I claim for it, it should provide a general framework for the responsible use of technologies, and the responsible innovation of social epistemic systems. (shrink)

On a traditional or default view of the grasping or understanding of a singular proposition by an individual, it is assumed to be a unitary or holistic activity. However, naturalistic views of cognition plausibly could analyze propositional thinking in terms of more than one distinctive functional stage of cognitive processing, suggesting at least the potential legitimacy of a non-unitary analysis of propositional grasping. We outline a novel dual-component view of this kind, and show that it is well supported by current (...) cognitive science research. (shrink)

It is axiomatic for most African scholars that the colonizers are responsible for the present problems facing the African continent. This is given much credence by Maduabuchi Dukor citing a barrage of issues which in summary pointed to the fact that the legacy of the colonizers to the African continent was ill willed to create chaos and therefore to make the African perpetually dependent on the colonizers. This paper accepts this fact but insists that the African as a human being (...) with free will and responsibility cannot continue to blame the colonizers when he has choice either to reject the colonial predetermined events or to accept them taking responsibility for his actions.

This book is the outcome of a series of lectures on art-related topics which Margolis gave in various places, including Finland, Russia, Japan and the USA, from 1995 through 1997. Mainly these lectures vividly distill views which Margolis has developed more fully elsewhere. Also, as his readers know, Margolis has an unusually allencompassing and closely integrated series of views on almost all of the main issues concerning both art and philosophy generally. Thus the task of a reviewer of this book (...) is the difficult one of somehow coming to terms and finding something useful to say (in a brief compass) on the full sweep of Margolis's philosophy as encapsulated by these lectures.

This article further explains and develops a recent, comprehensive semantic naturalization theory, namely the interactive indexing (II) theory as described in my 2008 Minds and Machines article Semantic Naturalization via Interactive Perceptual Causality (Vol. 18, pp. 527–546). Folk views postulate a concrete intentional relation between cognitive states and the worldly states they are about. The II theory eliminates any such concrete intentionality, replacing it with purely causal relations based on the interactive theory of perception. But intentionality is preserved via purely (...) abstract propositions about the world that index, or correlate with, appropriate cognitive states. Further reasons as to why intentionality must be abstract are provided, along with more details of an II-style account of representation, language use and propositional attitudes. All cognitive representation is explained in terms of classification or sorting dispositions indexed by appropriate propositions. The theory is also related to Fodor’s representational theory of mind, with some surprisingly close parallels being found in spite of the purely dispositional basis of the II theory. In particular, Fodor’s insistence that thinking about an item cannot be reduced to sorting dispositions is supported via a novel two-level account of cognition—upper level propositional attitudes involve significant intermediate processing of a broadly normative epistemic kind prior to the formation of sorting dispositions. To conclude, the weak intentional realism of the II theory—which makes intentional descriptions of the world dispensable—is related to Dennett’s ‘intentional stance’ view, and distinguished from strong (indispensable) intentional realist views. II-style dispositions are also defended. (shrink)

I argue that there is an ambiguity in the concept of indiscernibility as applied to objects, because there are two different categories of properties, associated with two different ways in which all of the pre-theoretical 'properties' of an object may be identified. In one structural way, identifications of properties are independent of any particular spatial orientation of the object in question, but in another 'field' way, identifications are instead dependent on an object's particular spatial orientation, so that its properties as (...) thus identified in one orientation are distinct from its properties as identified in any other orientation--all of which ‘field’ properties must hence also be distinct from the previous structurally defined properties. -/- To accommodate the two kinds of intrinsic properties, the standard concept of indiscernibility is redefined as structural indiscernibility, while a new concept of field indiscernibility is introduced. I argue among other things that, though two objects may be structurally indiscernible under all orientational (and other) conditions, those objects may nevertheless fail to have field indiscernibility with each other under some orientational conditions. I also briefly discuss the implications of these results for general issues about the nature of properties, and of realist versus nominalist approaches to them. -/- . (shrink)

Utilitarian (U.) theories must be capable of being applied in practical reasoning, or they would have no value as a guide to rational conduct. However, I show that epistemic extensions to U. theories produce logical confusion. Basic questions about what one needs to know in order to apply a U. analysis embroil one in an infinite regress. And attempts to incrementally apply U. either are no help at all (leaving one entirely 'in the dark'), or in general constitute arbitrary gambles (...) which no practical reasoner could defend taking. These problems are serious enough to completely discredit U. theories as having any relevance to practical reasoning. (shrink)

Portraits of Wittgenstein and Hume are used as test cases in some preliminary investigations of a new kind of philosophical picture. Such pictures are produced via a variety of visual transformations of the original portraits, with a final selection for display and discussion being based on the few results that seem to have some interesting relevance to the character or philosophical views of the philosopher in question.

In the performing arts, including music, theater, dance and so on, theoretical issues both about artworks and about performances of them must be dealt with, so that their theoretical analysis is inherently more complex and troublesome than that of nonperforming arts such as painting or film, in which primarily only artworks need to be discussed. Thus it is especially desirable in the case of the performing arts to look for defensible broad theoretical simplifications or generalizations that could serve to unify (...) and potentially comprehensively explain these difficult cases.

thesis as to the inseparability of the perception of a picture and the perception of its subject matter, making use of a recently developed ‘interpretive’ theory of pictorial representation, according to which a picture is represented by its physical vehicle, so that a picture is itself part of the representational content of the vehicle—which picture in turn interpretively represents its subject matter. I also show how Richard Wollheim's own twofoldness thesis, along with related views of his, might be vindicated by (...) reinterpretation along similar lines, and conclude by showing that Ernst Gombrich too may be protected from some standard criticisms of his views—which views are also consistent with those of Wollheim as thus reinterpreted.
