The interaction between cavity modes and optical transitions leads to new coupled light-matter states in which the energy is periodically exchanged between the matter states and the optical mode. Here we present experimental evidence of optical strong coupling between modes of individual sub-wavelength metamaterial nanocavities and engineered optical transitions in semiconductor heterostructures. We show that this behaviour is generic by extending the results from the mid-infrared to the near-infrared. Using mid-infrared structures, we demonstrate that the light-matter coupling occurs at the (...) single resonator level and with extremely small interaction volumes. We calculate a mode volume of 4.9 × 10 from which we infer that only ~2,400 electrons per resonator participate in this energy exchange process. (shrink)

This article illustrates some of the difficulties of defining discrimination and briefly sketches the benefits and desiderata of doing so. It then examines and defines generic direct discrimination as an agent treating two groups differently because of the property that defines one of the groups as a group, in a way that is worse for that group, clarifying each of these three conditions in turn. It considers two arguments for further conditions: that an act must target one among a particular (...) set of groups to constitute discrimination, and that an act must be in some sense morally wrong to constitute discrimination. It concludes that while these objections are forceful it may be the case that they illustrate that we employ multiple, partly overlapping concepts of discrimination, and that it may be more important to recognize this heterogeneity than it is to attempt to establish a dominant or unitary definition.

The article explores one prominent account of what makes discrimination morally bad (when it is) – the disrespect-based account. The article first reviews and clarifies the account, arguing that it is most charitably understood as the claim that discrimination is morally bad when the discriminator gives lower weight to reasons grounded in the moral status of the discriminatee(s) in her decision-making. It then presents three challenges to the account, and reviews a recent argument in defense of it. The first challenge (...) is the fact that intuitions that might support the disrespect-based account can also be explained by reference to the fact that disrespect reflects poorly on the moral character of the discriminator. The second challenge is that there are cases where disrespectful discrimination is not intuitively worse than non-disrespectful discrimination. The third challenge is that the disrespect-based account has difficulties explaining our intuitions about cases of “doing right for the wrong reasons”. Finally, pace a recent argument in its defense, cases of harmless and apparently morally bad discrimination are plausibly best explained by other factors than disrespect. In the light of this analysis, the article concludes that the disrespect-based account should be abandoned. (shrink)

Since the middle of the 20th century, philosophers and legal scholars have debated the precise definition of punishment. This chapter surveys the debate, identifies six potential conditions of punishment, and critically reviews each of them: 1) the response condition, which holds that punishment must be in response to wrongdoing, 2) the culpability condition, which holds that punishment must be of a person morally responsible for wrongdoing, 3) the authority condition, which holds that punishment must be imposed by a relevant authority, (...) 4) the hard treatment condition, which holds that punishment must impose hard consequences on the punishee, 5) the intentionality condition, which holds that punishment must be intentional, and 6) the censure condition, which holds that punishment must communicate disapproval. The article argues that it is often unclear that there is a version of the condition that provides optimal lexical fit. It discusses the implications of this analysis, and concludes that there may be less reason to worry about the lack of an authoritative definition than has sometimes been assumed, but that definitional clarity remains an objective worth pursuing.

Different translations of Plutarch's De Pythiae oraculis 404B reflect an interpretative difficulty not yet adequately thematized by exegetes. Plutarch's dialogues on the Delphic oracle describe two perspectives on mantic inspiration: possession prophecy, where the god takes over the prophetess as a passive apparatus, and stimulation prophecy, where the god incites the prophecy, but the prophetess delivers the oracle through her own faculties. Plutarch understands the Pythia at Delphi to exhibit stimulation prophecy, not possession. One of his metaphors for inspiration comes (...) from the theatre: the god ‘puts the oracle into the Pythia's mouth, like an actor speaking through the mask’ (De Pyth. or. 404B [Russell]). Some translators take the metaphor as describing possession prophecy (Goodwin), while others take it as stimulation prophecy (Babbitt)—in other words, it may describe the view Plutarch affirms or the view he rejects. This article assesses the two alternatives, concluding that the theatre metaphor describes possession prophecy. (shrink)

In this article I critically examine a standard feature in conceptions of discrimination: the group-criterion, specifically the idea that there is a limited and definablegroup of traits that can form the basis of discrimination. I review two types of argument for the criterion. One focuses on inherently relevant groups and relies ultimately on luck-egalitarian principles; the other focuses on contextually relevant groups and relies ultimately on the badness of outcomes. I conclude that as neither type of argument is convincing, the (...) criterion is morally arbitrary, and as such untenable. Finally, I suggest both some of the conceptual and some of the practical implications of abandoning the criterion. (shrink)

The article analyses the concept of indirect discrimination, arguing first that existing conceptualisations are unsatisfactory and second that it is best understood as equal treatment that is disadvantageous to the discriminatees because of their group-membership. I explore four ways of further refining the definition, arguing that only an added condition of moral wrongness is at once plausible and helpful, but that it entails a number of new problems that may outweigh its benefits. Finally, I suggest that the moral wrongness of (...) indirect discrimination is best accounted for in terms of the harm it does to discriminatees, and sketch three ways in which it may do so. I conclude that the analysis provides both a clearer understanding of the concept of indirect discrimination as well as indirect support for a harm-based account of the wrongness of discrimination, while suggesting that our moral obligations qua non-discrimination may be more extensive than is frequently assumed.

Criminalisation of prostitution, and minority rights for disabled persons, are important contemporary political issues. The article examines their intersection by analysing the conditions and arguments for making a legal exception for disabled persons to a general prohibition against purchasing sexual services. It explores the badness of prostitution, focusing on and discussing the argument that prostitution harms prostitutes, considers forms of regulation and the arguments for and against with emphasis on a liberty-based objection to prohibition, and finally presents and analyses three (...) arguments for a legal exception, based on sexual rights, beneficence, and luck egalitarianism, respectively. It concludes that although the general case for and against criminalisation is complicated there is a good case for a legal exception. (shrink)

The New Evil Demon problem has been hotly debated since the case was introduced in the early 1980’s (e.g. Lehrer and Cohen 1983; Cohen 1984), and there seems to be recent increased interest in the topic. In a forthcoming collection of papers on the New Evil Demon problem (Dutant and Dorsch, forthcoming), at least two of the papers, both by prominent epistemologists, attempt to resist the problem by appealing to the distinction between justification and excuses. My primary aim here is (...) to critically evaluate this new excuse maneuver as a response to the New Evil Demon problem. -/- Their response attempts to give us reason to reject the idea that victims of the New Evil Demon have justification for believing as they do. I shall argue that this approach is ultimately unsuccessful, however much of value can be learned from these attempts. In particular, progress in the debate can be made by following those who advance the excuse maneuver and make explicit the connection between epistemic justification and epistemic norms. By doing so, the questions being debated are clarified, as is the methodology being used to attempt to answer them. (shrink)

This article analyses proportionality as a potential element of a theory of morally justified surveillance, and sets out a teleological account. It draws on conceptions in criminal justice ethics and just war theory, defines teleological proportionality in the context of surveillance, and sketches some of the central values likely to go into the consideration. It then explores some of the ways in which deontologists might want to modify the account and illustrates the difficulties of doing so. Having set out the (...) account, however, it considers whether the proportionality condition is necessary to a theory of morally justified surveillance. The article concludes that we need and should apply only a necessity condition, but notes that proportionality considerations may retain some use in in practice, as a form of coarse‐grained filter applied before assessing necessity when deliberating the permissibility of potential forms of surveillance.

The concept of surveillance has recently been complemented by the concept of sousveillance. Neither term, however, has been rigorously defined, and it is particularly unclear how to understand and delimit sousveillance. This article sketches a generic definition of surveillance and proceeds to explore various ways in which we might define sousveillance, including power differentials, surreptitiousness, control, reciprocity, and moral valence. It argues that for each of these ways of defining it, sousveillance either fails to be distinct from surveillance or to (...) provide a generally useful concept. As such, the article concludes that academics should avoid the neologism, and simply clarify what sense of surveillance is at stake when necessary. (shrink)

There are various equivalent formulations of the Church-Turing thesis. A common one is that every effective computation can be carried out by a Turing machine. The Church-Turing thesis is often misunderstood, particularly in recent writing in the philosophy of mind.

Over the past decade, police departments in many countries have experimented with and increasingly adopted the use of police body-worn cameras. This article aims to examine the moral issues raised by the use of PBWCs, and to provide an overall assessment of the conditions under which the use of PBWCs is morally permissible. It first reviews the current evidence for the effects of using PBWCs. On the basis of this review the article sets out a teleological argument for the use (...) of PBWCs. The final two sections of the article review two deontological objections to the use of PBWCs: the idea that use of PBWCs is based on or expresses disrespectful mistrust, and the idea that the use of PBWCs violates a right to privacy. The article argues that neither of these objections is persuasive, and concludes that we should conditionally accept and support the use of PBWCs. (shrink)

The conceptualization and moral analysis of discrimination constitutes a burgeoning theoretical field, with a number of open problems and a rapidly developing literature. A central problem is how to define discrimination, both in its most basic direct sense and in the most prominent variations. A plausible definition of the basic sense of the word understands discrimination as disadvantageous differential treatment of two groups that is in some respect caused by the properties that distinguish the groups, but open questions remain on (...) whether discrimination should be restricted to concern only particular groups, as well as on whether it is best conceived as a descriptive or a moralized concept. Furthermore, since this understanding limits direct discrimination to cases of differential treatment, it requires that we be able to draw a clear distinction between equal and differential treatment, a task that is less simple than it may appear, but that is helpful in clarifying indirect discrimination and statistical discrimination. The second major problem in theorizing discrimination is explaining what makes discrimination morally wrong. On this issue, there are four dominant contemporary answers: the valuational and expressive disrespect accounts, which hold that discrimination is wrong when and if the discriminator misestimates or expresses a misestimate of the moral status of the discriminatee; the unfairness account, which holds that discrimination is wrong when and if the discriminator unfairly increases inequality of opportunity; and the harm account, which holds that discrimination is wrong when and if the discriminator harms the discriminatee. Each of these accounts, however, faces important challenges in simultaneously providing a persuasive theoretical account and matching our intuitions about cases of impermissible discrimination.

This article analyses the moral status of racial profiling from a consequentialist perspective and argues that, contrary to what proponents of racial profiling might assume, there is a prima facie case against racial profiling on consequentialist grounds. To do so it establishes general definitions of police practices and profiling, sketches out the costs and benefits involved in racial profiling in particular and presents three challenges. The foundation challenge suggests that the shifting of burdens onto marginalized minorities may, even when profiling (...) itself is justified, serve to prolong unjustified police practices. The valuation challenge argues that although both costs and benefits are difficult to establish, the benefits of racial profiling are afflicted with greater uncertainty than the costs, and must be comparatively discounted. Finally, the application challenge argues that using racial profiling in practice will be complicated by both cognitive and psychological biases, which together reduce the effectiveness of profiling while still incurring its costs. Jointly, it is concluded, these challenges establish a prima facie case against racial profiling, so that the real challenge consists in helping officers practice the art of the police and not see that which it is useless that they should see.

Algorithmic discrimination has rapidly become a topic of intense public and academic interest. This article explores three issues raised by algorithmic discrimination: 1) the distinction between direct and indirect discrimination, 2) the notion of disadvantageous treatment, and 3) the moral badness of discriminatory automated decision-making. It argues that some conventional distinctions between direct and indirect discrimination appear not to apply to algorithmic discrimination, that algorithmic discrimination may often be discrimination between groups, as opposed to against groups, and that it is (...) not necessarily the case that morally bad algorithmic discrimination gives us reason to not use automated decision-making. For each of the three issues, the article explores implications for algorithmic discrimination, suggests some alternative answers, and clarifies how we may want to think of discrimination more broadly in light of lessons drawn from the context of algorithmic discrimination.

Over the past decade, scholars, institutions, and activists have voiced strong concerns about the potential of automated decision systems to indirectly discriminate against vulnerable groups. This article analyses the ethics of algorithmic indirect discrimination, and argues that we can explain what is morally bad about such discrimination by reference to the fact that it causes harm. The article first sketches certain elements of the technical and conceptual background, including definitions of direct and indirect algorithmic differential treatment. It next introduces three (...) prominent accounts of fairness as potential explanations if the badness of algorithmic indirect discrimination, but argues that all three are vulnerable to powerful levelling-down-style objections. Instead, the article demonstrates how proper attention to the way differences in decision-scenarios affect the distribution of harms can help us account for intuitions in prominent cases. Finally, the article considers a potential objection based on the fact that certain forms of algorithmic indirect discrimination appear to distribute rather than cause harm, and notes that we can explain how such distributions cause harm by attending to differences in individual and group vulnerability.

Increasing vaccine hesitancy among parents in high income countries and the resulting drop in early childhood immunisation constitute an important public health problem, and raise the issue of what policies might be taken to promote higher rates of vaccination. This article first outlines the background of the problem of increasing vaccine hesitancy. It then explores the pros and cons of three types of policy: 1) Interventions focused on increasing awareness of the benefits of vaccination while eliminating mistaken perceptions of risks. (...) 2) “Nudges”, which make certain choices more likely to be voluntarily chosen by manipulating the decision environment. 3) Policies that impose costs to make non-vaccination undesirable even for parents who are hesitant. It argues that a wide range of policies, including coercive policies, is desirable from a public health perspective, as the least intrusive policies alone are unlikely to achieve and sustain the important public good of herd immunity.

Despite the attention equality before the law has received, both laudatory and critical, peculiarly little has been done to precisely define it. The first ambition of this paper is to remedy this, by exploring the various ways in which a principle of equality before the law can be understood and suggest a concise definition. With a clearer understanding of the principle in hand we are better equipped to assess traditional critique of the principle. Doing so is the second ambition of (...) this paper. I will argue that traditional criticisms are unpersuasive, but that there is a different, powerful argument against equality before the law. The third ambition of the paper is to argue that there is a sense, overlooked by both proponents and critics, in which the principle still captures something important, albeit at the cost of shifting from intrinsic to instrumental value.

This article clarifies what a neuroscience challenge to criminal justice must look like by sketching the basic structure of the argument, gradually filling out the details and illustrating the conditions that must be met for the challenge to work. In the process of doing so it explores influential work by Joshua Greene and Jonathan Cohen, and Stephen Morse respectively, arguing that the former should not be understood to present a version of the challenge, and that the latter's argument against the (...) challenge is unpersuasive. This analysis allows the article to flesh out the challenge, and demonstrate why it is currently non-completeable. However, the paper argues that contrary to what is often assumed the burden of proof falls on the defenders of criminal justice, and that they will find meeting it a monumental task. (shrink)

The article analyses the necessary conditions an argument for popular punishment would need to meet, and argues that it faces the challenge of a dilemma of reasonableness: either popular views on punishment are unreasonable, in which case they should carry no weight, or they are reasonable, in which case the reasons that support them, not the views, should carry weight. It proceeds to present and critically discuss three potential solutions to the dilemma, arguing that only an argument for the beneficial (...) effects of coherence between popular views and penal policy is persuasive, but that it makes popular punishment less important than proponents claim, and offers a justification proponents will find it difficult to advance.
