According to First-Person Realism, one's own first-person perspective on the world is metaphysically privileged in some way. After clarifying First-Person Realism by reference to parallel debates in the metaphysics of modality and time, I survey eight different arguments in favor of First-Person Realism.

The singularity hypothesis is a radical hypothesis about the future of artificial intelligence on which self-improving artificial agents will quickly become orders of magnitude more intelligent than the average human. Despite the ambitiousness of its claims, the singularity hypothesis has been defended at length by leading philosophers and artificial intelligence researchers. In this paper, I argue that the singularity hypothesis rests on scientifically implausible growth assumptions. I show how leading philosophical defenses of the singularity hypothesis (Chalmers 2010, Bostrom 2014) fail (...) to overcome the case for skepticism. I conclude by drawing out philosophical implications of this discussion for our understanding of consciousness, personal identity, digital minds, existential risk, and ethical longtermism.

When our choice affects some other person and the outcome is unknown, it has been argued that we should defer to their risk attitude, if known, or else default to use of a risk avoidant risk function. This, in turn, has been claimed to require the use of a risk avoidant risk function when making decisions that primarily affect future people, and to decrease the desirability of efforts to prevent human extinction, owing to the significant risks associated with continued human (...) survival. I raise objections to the claim that respect for others’ risk attitudes requires risk avoidance when choosing for future generations. In particular, I argue that there is no known principle of interpersonal aggregation that yields acceptable results in variable population contexts and is consistent with a plausible ideal of respect for others’ risk attitudes in fixed population cases.

This paper is on the metaphysics and normativity of Jewish identity. It starts with a metaphysical question: “Can a Jewish person become non-Jewish?” This question and the related question “What is Jewishness?” are both ambiguous, because the word “Jewish” is ambiguous. The paper outlines five concepts of Jewishness: halachic, religious, ethnic, and cultural Jewishness, as well as being Jewish in the sense of belonging to the Jewish community. In some of these senses of “Jewish” a Jewish person is always Jewish. (...) In other senses a Jewish person can become non-Jewish. The paper closes with a normative question: Should a person who is Jewish, in the sense of belonging to the Jewish community, become non-Jewish? The paper explains reasons for and against staying in the Jewish community and in doing so highlights a tension, rather than telling anyone how they should identify. (shrink)

This is a corrected version of the final proofs. I've fixed a number of typos, and corrected a blunder in chapter 4. In chapter 4 I say that 'this is this' is analytic, and 'this is not this' is antonymous. This is inconsistent with what I say in chapter 5, and not what I actually think. Rather, 'this is this' is taugologous, and 'this is not this' is contradictory. Analyticity and autnonmy are sense properties while tautologousness and contradictoriness are formal (...) logical properties. Heading, ToC and Index updated accordingly. (Oxford will make these corrections in their online version and in future print runs.). (shrink)

Experimental balance is usually understood as the control for the value of the conditions, other than the one under study, which are liable to affect the result of a test. We will discuss three different approaches to balance. ‘Millean balance’ requires to identify and equalize ex ante the value of these conditions in order to conduct solid causal inferences. ‘Fisherian balance’ measures ex post the influence of uncontrolled conditions through the analysis of variance. In ‘efficiency balance’ the value of the (...) antecedent conditions is decided ex ante according to the efficiency they yield in the estimation of the treatment outcome. Against some old arguments by John Worrall, we will show that in both Fisherian and efficiency balance there are good reasons to randomize the allocation of treatments, in particular when there is no agreement among experimenters as to the antecedent conditions to be controlled for.

Suppose someone is brought up as an orthodox Jew, and so only eats kosher, is very conservative sexually, etc. Suppose they then find out that this Judaism stuff is just all a big mistake. If they then regret all the shrimp they could have eaten, all the sex!, this makes perfect sense. Not so, however, if someone finds out that moral realism is false, and they now regret all the fun they could have had hurting people’s feeling, etc. Even if (...) this does make sense, there’s a strong disanalogy between the moral and the religious case. This asymmetry, on a realist picture of morality, calls for explanation. This chapter tries to explain it. The discussion engages some topics familiar from objections to Robust realism—the why-be-moral challenge, the status of de-dicto moral motivation, and whether and why we should care about the moral properties, robustly realistically understood.

The causal closure of the physical poses a familiar causal exclusion problem for the special sciences that stems from the idea that if closure is true, then fundamental physical properties do all the causal work involved in bringing about physical effects. In this paper I aim to show that the strongest causal closure principle that is not ruled out by some simple physics in fact allows for a certain kind of downward causation, which in turn makes room for robust special (...) science autonomy. I focus on the case of vector composition, arguing that it involves irreducibly multilevel causation. To give a complete causal explanation of what goes on in cases that involve the effects of multiple forces, we need to appeal not only to the fundamental properties that generate those forces, but also to geometric properties that determine how multiple vectors compose. However, if all the causal work involved in such cases were due to fundamental physical properties, there would be a one-level explanation available. Hence, I argue, it cannot be the case that fundamental physical properties do all the causal work. The extra causal work, I suggest, comes from the fact that the causal powers bestowed by fundamental physical properties have irreducibly geometric manifestation conditions. I defend the resulting form of downward causation as a solution to the problem of special science autonomy, and discuss two potential accounts of its source, in terms of the debate between kinematic and dynamic theories of the origins of spacetime symmetries.

I criticize the widely-defended view that the quantum measurement problem is an example of underdetermination of theory by evidence: more specifically, the view that the unmodified, unitary quantum formalism (interpreted following Everett) is empirically indistinguishable from Bohmian Mechanics and from dynamical-collapse theories like the GRW or CSL theories. I argue that there as yet no empirically successful generalization of either theory to interacting quantum field theory and so the apparent underdetermination is broken by a very large class of quantum experiments (...) that require field theory somewhere in their description. The class of quantum experiments reproducible by either is much smaller than is commonly recognized and excludes many of the most iconic successes of quantum mechanics, including the quantitative account of Rayleigh scattering that explains the color of the sky. I respond to various arguments to the contrary in the recent literature. (shrink)

The thought of François Jullien has made valuable contributions to contemporary philosophy, primarily by enriching the interpretation of certain classic themes through the uniqueness of ancient Chinese wisdom. This approach has revealed aspects that Western philosophy, with its metaphysics focused on being, has overlooked. Among these aspects, Jullien has drawn attention to how a series of resources of what could be called ‘Christian thought’ have remained unthought-of, at least from a philosophical perspective. The central question of this research is whether (...) this Christian logic represents just another resource, among several, that Jullien has utilized in his intellectual work, or if it also constitutes one of the fundamental sources of his own work and the beginnings of possible de-coincidence from the philosophy of being. The conclusions indicate a notable and indispensable presence of these Christian notions in his argumentative proposal, albeit without resorting to faith. This study will begin by reviewing the main theses of the French philosopher and, at the same time, will describe how he has been relating and discussing them with Christian doctrine. (shrink)

This paper develops a theory of belief and belief ascription which retains the core of the received Propositionalist theory but which, unlike the Propositionalist theory, is compatible with both Direct Reference and Individualism about belief. The focus is on developing an alternative analysis of belief ascriptions, drawing out its implications, and applying it to some standard problems. On that analysis, ascriptions involving directly referential embedded terms are seen as roughly characterizing, but not specifying, the contents of beliefs. This feature is (...) what makes it possible to maintain both Direct Reference and Individualism. (shrink)

Psychologists debate whether mental attributes can be quantified or whether they admit only qualitative comparisons of more and less. Their disagreement is not merely terminological, for it bears upon the permissibility of various statistical techniques. This article contributes to the discussion in two stages. First it explains how temperature, which was originally a qualitative concept, came to occupy its position as an unquestionably quantitative concept (§§1–4). Specifically, it lays out the circumstances in which thermometers, which register quantitative (or cardinal) differences, (...) became distinguishable from thermoscopes, which register merely qualitative (or ordinal) differences. I argue that this distinction became possible thanks to the work of Joseph Black, ca. 1760. Second, the article contends that the model implicit in temperature’s quantitative status offers a better way for thinking about the quantitative status of mental attributes than models from measurement theory (§§5–6).

Political fact-checkers evaluate the truthfulness of politicians’ claims. This paper contributes to an emerging scholarly debate on whether fact-checkers treat political parties differently in a systematic manner depending on their ideology (bias). We first examine the available approaches to analyze bias and then present a new approach in two steps. First, we propose a logistic regression model to analyze the outcomes of fact-checks and calculate how likely each political party will obtain a truth score. We test our model with a (...) sample of fact-checks from Newtral, a major Spanish fact-checker. Our model would signal bias under two assumptions: a) all political parties are on average equally accurate in their statements; b) the verification method gives precise instructions and is implemented systematically. We investigate this second assumption with a series of interviews with Newtral fact-checkers. We show that standard verification protocols are so loosely implemented that fact-checks reflect a set of journalistic decisions, rather than a bias in the statistical sense. We call for a more rigorous definition of verification methods as a pre-requisite for an unbiased assessment of politician’s claims. (shrink)

El presente trabajo de investigación tiene como objeto el estudio de la legislación penal en la República de Colombia desde 1890 hasta la actualidad con la ley 599 de 2000, este último conocido como el vigente Código Penal.

Longtermism is the thesis that in a large class of decision situations, the best thing we can do is what is best for the long-term future. The scope question for longtermism asks: how large is the class of decision situations for which this is true? In this paper, I suggest that the scope of longtermism may be narrower than many longtermists suppose. I identify a restricted version of longtermism: swamping axiological strong longtermism (swamping ASL). I identify three scope-limiting factors - (...) probabilistic and decision-theoretic phenomena which, when present, tend to reduce the prospects for swamping ASL. I argue that these scope-limiting factors are often present in human decision problems, then use two case studies from recent discussions of longtermism to show how the scope-limiting factors lead to a restricted, if perhaps nonempty, scope for swamping ASL.

La propuesta de Jullien se caracteriza por poner de relieve análisis sobre la existencia cotidiana que la tradición filosófica había tomado por demasiado contingentes y, por lo mismo, había dejado al tratamiento del arte, la poesía y la literatura. En este sentido, el filósofo ha tenido como una de sus líneas de trabajo la temática del encuentro y la intimidad entre sujetos. El objetivo de esta investigación es buscar si la noción de "encuentro" tiene consecuencias metafísicas y no sólo antropológicas (...) en su doctrina. Y, viceversa, indagaremos si, según Jullien, la disposición o no al encuentro y el ingreso del otro a la existencia depende de determinadas posiciones metafísicas previas. (shrink)

This manuscript reports on a landmark symposium on the ethical, legal and technical challenges of xenotransplantation in the UK. King’s College London, with endorsement from the British Transplantation Society (BTS), and the European Society of Organ Transplantation (ESOT), brought together a group of experts in xenotransplantation science, ethics and law to discuss the ethical, regulatory and technical challenges surrounding translating xenotransplantation into the clinical setting. The symposium was the first of its kind in the UK for 20 years. This paper (...) summarises the content of the expert lectures showcasing the progress which has been made in xenotransplantation including—the history of xenotransplantation, advances in gene edited animals and progress towards clinical xenotransplantation. We then set out the ethical and legal issues still to be resolved. Finally, we report the themes of the roundtable discussion highlighting areas of consensus and controversy. While the detail of the legal discussion was directed towards the UK, the principles and summary reported here are intended to be applicable to any jurisdiction seeking to implement clinical xenotransplantation.

Various scientists and philosophers have heavily criticized what they see as problematic forms of ‘nutritional reductionism’ or ‘nutritionism’ whereby studying food–health interactions at the level of isolated food components produces largely misguided science and misleading interpretations. However, the exact target of these diverse criticisms remains elusive, and its implications are overstated, which may hinder scientific understanding. To better identify the types of flaws supposedly hindering reductionist research, we disentangle three types of reductionist claims to better determine what the debate is (...) about and to propose ways to move it forward. We then present a qualified defence of the reductionist programme that hinges on the ability to identify nutritional causes that make a difference, which we illustrate through central examples in the history of nutrition. This defence is taken further by using insights from the philosophy of mechanisms to analyse how the field of nutritional ecology offers a synthetic framework to explain, generate, and test predictions about nutrient–organism interactions, which is premised on the biological mechanisms of nutrient-specific appetite regulation. The result, which we call ‘synthetic reductionism’, avoids many, though perhaps not all, of the challenges raised by anti-reductionists, and also highlights the potential of reductionism to identify nutritional difference makers.

Drawing on the pragmatic turn in contemporary social theory, we explore how corporate elites accused of corruption in the context of weak institutions engage in their justification works. Empirically, we focus on three high-profile corruption scandals that shook Ghana between 2010 and 2020 and inspired widespread public condemnation. Publicly accessible archival documents, such as court reporting, newspaper stories, press conferences, and the digital footprints of corporate elites implicated in the scandals provide data for our inquiry. Focussing on the juxtaposition of (...) ‘sayings’ and ‘doings’, the findings show justification as performative, and rooted in contextual pragmatism that acknowledges the plurality of logics situated between self-interest and folk-logic. Within this framework, the domestic and civic orders of worth emerge as most prominent, with the justification processes manifesting through _victimising, scapegoating,_ and _crusading_. Building on these insights, we develop a framework that highlights how the use of justifications serves as a critique of the inadequacies within climates of weak institutional frameworks consequently fostering an atmosphere conducive to framing unethical conducts as morally acceptable.

Arguments concerning divine conservation and concurrence often assume that actions of certain descriptions would be superfluous if God were to perform them, and it is then concluded that God does not perform such actions. In particular, it often seems that atomic actions cannot be the result of cooperative activity between God and creatures since there is no apparent way to divide the labor between the two. However, the actions that are atomic in one model of divine action may not be (...) atomic on another. On fine-grained models there may be unexpected prospects for nonredundant divine action.

Transdisciplinary research knits together knowledge from diverse epistemic communities in addressing social-environmental challenges, such as biodiversity loss, climate crises, food insecurity, and public health. This paper reflects on the roles of philosophy of science in transdisciplinary research while focusing on Indigenous and other subaltern forms of knowledge. We offer a critical assessment of demarcationist approaches in philosophy of science and outline a constructive alternative of transdisciplinary philosophy of science. While a demarcationist focus obscures the complex relations between epistemic communities, transdisciplinary (...) philosophy of science provides resources for meeting epistemic and political challenges of collaborative knowledge production.

The aim of this article is to briefly spell out why corporate moral agency is a fallacy and to show how this conclusion should shift the field of business ethics more in the direction of political philosophy and the rule of law. An argument based on a false assumption can be valid, but it cannot be sound. If corporate moral agency is a fallacy, and thus also moral prescriptions for corporations, how do we salvage the field of business ethics? To (...) the extent that business ethics is about corporate behaviour (rather than individual managerial behaviour), the field can shift its foundational paradigm from ethics (which requires the attributes of moral agency) to legal accountability (which can be imposed instrumentally on corporate legal agents). By letting our elected representatives legislate the norms of acceptable corporate behaviour we can hold corporate legal entities legally accountable. What these norms should be then becomes the central focus of business ethics seen through the lens of political philosophy. (shrink)

The question of whether Everettian quantum mechanics (EQM) justifies the existence of metaphysical indeterminacy has recently come to the fore. Metaphysical indeterminacy has been argued to emerge from three sources: coherent superpositions, the indefinite number of branches in the quantum multiverse and the nature of these branches. This paper reviews the evidence and concludes that those arguments don’t rely on EQM alone and rest on metaphysical auxiliary assumptions that transcend the physics of EQM. We show how EQM can be ontologically (...) interpreted without positing metaphysical indeterminacy by adopting a deflationary attitude towards branches. Two ways of developing the deflationary view are then proposed: one where branches are eliminated, and another where they are reduced to the universal quantum state. (shrink)

This chapter argues that the principle of nationality offers a perspective on the secession issue that avoids condoning a secessionist free‐for‐all without forcing us to defend existing state boundaries regardless. It suggests the need for a contextual approach to secession, examining the extent to which different groups have or have not evolved separate national identities, how minorities are likely to fare under various possible regimes, and whether partial autonomy regimes might be more justified than secession.

A family of familiar linguistic tests purport to help identify when a term is ambiguous. These tests are philosophically important: a familiar philosophical strategy is to claim that some phenomenon is disunified and its accompanying term is ambiguous. The tests have been used to evaluate disunification proposals about causation, pain, and knowledge, among others. -/- These ambiguity tests, however, have come under fire. It has been alleged that the tests fail for polysemy, a common type of ambiguity, and one that (...) is at issue in philosophically interesting cases. Furthermore, the objection that the tests fail for polysemy is often taken to be an undeniable bit of linguistic data. -/- We argue that this is mistaken. The objection implicitly relies on controversial assumptions about how to account for copredicational sentences, in which a single argument is ascribed prima facie incompatible properties. Furthermore, on several viable theories of copredication, the objection fails. However, our discussion also reveals that even if ambiguity tests are preserved, they may be significantly harder to execute than previously thought. (shrink)

Longtermists have recently argued that it is overwhelmingly important to do what we can to mitigate existential risks to humanity. I consider three mistakes that are often made in calculating the value of existential risk mitigation.

I use this discussion to draw four positive lessons for the study of existential risk. -/- (...) . (shrink)

A key philosophical feature of Peter Jackson’s film interpretation of J.R.R. Tolkien’s The Lord of the Rings is its use of fantasy to inspire a “recovery” of the actual or, in other words, a reawakening to the beauty of nature and the many possible ways of living in healthier ecological relation to the world. Though none of these ways is perfectly achieved, this pluralistic view is demonstrated in the various lifeways of Hobbits, Elves, Men, and Ents. All of the positive (...) relationships embodied in the films—to trees, mountains, horses, and vegetable gardens—involve loving care and attention, receiving nourishment and livelihood without instrumentalization, or reducing nature to mere resource. The films also vividly display a variety of ugly and destructive ways of using the land to accrue power and wealth. These noxious ways, specifically because they actively destroy the lands that they use, always need more. They will thus eventually annihilate the beautiful ways of being if they are not actively resisted. Some of those who would rather be tending their own trees, gardens, or horses or even wandering in the wild forests must therefore turn their attention to struggle and resistance instead. This is a struggle full of grief, and at times even verging on despair, but it is marked by the refusal to give up hope. Indeed, what Jackson and Tolkien have to say about hope is as important in responding to the ecological crisis as anything they have to say about nature, inasmuch as they help to remind us that even in our own times, “there is still hope.”.

This essay reviews the recently released Handbook of Philosophy of Management, using it as a jumping off point to explore some potential confusions in contemporary philosophy of management. The handbook itself, comprising 58 articles and some 1,000 pages, is a milestone for the field. At the same time, it brings a few problems into sharp relief. I argue for more clarity about the distinction between the philosophy of management and the philosophy of management research. I make the case that logic (...) as a de facto method for conducting inquiry may or may not be useful, while logic as a de jure standard for evaluating its conclusions is indispensable. I develop the view that neither management nor management studies is properly considered a science, or even an applied science. I contend that the seminal contributions of Alasdair MacIntyre are unjustly neglected by the field. And I advance the thesis that perhaps the leading issue for the philosophy of management today is the question of the purpose of management, pointing in some suggested directions for answering the question.

On explanationist accounts of genealogical debunking, roughly, a belief is debunked when its explanation is not suitably related to its content. We argue that explanationism cannot accommodate cases in which beliefs are explained by factors unrelated to their contents but are nonetheless independently justified. Justification-specific versions of explanationism face an iteration of the problem. The best account of debunking is a probabilistic account according to which subject S’s justification J for their belief that P is debunked when S learns that (...) J is no more likely to be true on the hypothesis that P than on the hypothesis that ¬P. The probabilistic criterion is fully general, applying not only to cases where the learned undercutting defeater is a proposition about our beliefs or other mental states but to any case of undercutting defeat, providing the grounds for a debunking argument against the existence of a special, metacognitive debunking principle.

Seth MacFarlane’s space adventure, The Orville, is not “Family Guy in Space.” It is a social commentary of the most direct and compelling sort. Through satire, humor, and symbolism, The Orville explores the potential dangers of religion. It does so in individual episodes, such as “If the Stars Should Appear” and “Mad Idolatry,” as well as through the series as a whole in its depiction of how the Union resolves its political differences with the Krill and the Moclans. In this (...) chapter, we will look at how The Orville criticizes religion, both generally and specifically. We will see that while it is not a condemnation of all religious believers, it is a critique of religion itself, suggesting that it can become dangerous when it merges religious dogma with political power.

A sustainable supply chain management strategy reduces risks and meets environmental, economic and social objectives by integrating environmental and financial practices. In an ever-changing environment, supply chains have become vulnerable at many levels. In a global supply chain, carefully tracing a product is of great importance to avoid future problems. This paper describes a self-updating smart contract, which includes data validation, for tracing global supply chains using blockchains. Our proposal uses a machine learning model to detect anomalies on traceable data, (...) which helps supply chain operators detect anomalous behavior at any point in the chain in real time. Hyperledger Caliper has been used to evaluate our proposal, and obtained a combined average throughput of 184 transactions per second and an average latency of 0.41 seconds, ensuring that our proposal does not negatively impact supply chain processes while improving supply chain management through data anomaly detection.

Zetetic norms govern our acts of inquiry. Epistemic norms govern our beliefs and acts of belief formation. Recently, Jane Friedman (2020) has defended that we should think of these norms as conforming a single normative domain: epistemology should take a zetetic turn. Though this unification project implies a substantive re-elaboration of our traditional epistemic norms, Friedman argues that the reasons supporting the turn are robust enough to warrant its revisionary implications. In this paper, I suggest we should read Friedman’s proposal (...) as a dilemma. Either we believe the zetetic turn is well-motivated and undertake the task of looking for the proper revision of our traditional epistemic norms, or we take the revisionary implications of the turn to be unacceptable, in which case our challenge is to show why a zetetic epistemology is not a well-motivated project after all. After presenting this dilemma, I make a case for endorsing its second horn by presenting a two-pronged argument against Friedman’s project. First, I show that the revisionary implications of the zetetic turn are more far-reaching than expected. Second, I defend that the most persuasive reasons for endorsing the turn are not strong enough to support it. Taken together, these considerations speak against accepting the zetetic turn and the revisionary implications that come with it. (shrink)

In this paper, I develop two criticisms of L. Jonathan Cohen's influential a priori argument that human irrationality cannot be experimentally demonstrated. The first is that the argument depends crucially on the concept of a normal human but that no such concept suitable for Cohen's purposes is available. The second is that even if his argument were granted, his thesis of an unimpeachable human capacity for reasoning is not a defense of human reasoning, but rather amounts to the claim that (...) we cannot make any meaningful evaluative claims about human reasoning whatsoever.

Only few philosophers are fortunate enough to start single-handedly a new topic in philosophy. The Oxford philosopher J. O. Urmson is one of them. But at the time he wrote his seminal article, ‘Saints and Heroes’ (1958), he was certainly not aware of it.

In this article, I argue that if tacit knowledge of grammar is analyzable in functional‐computational terms, then it cannot ground linguistic meaning, structure, or sound. If to know or cognize a grammar is to be in a certain computational state playing a certain functional role, there can be no unique grammar cognized. Satisfying the functional conditions for cognizing a grammar G entails satisfying those for cognizing many grammars disagreeing with G about expressions' semantic, phonetic, and syntactic values. This threatens the (...) Chomskyan view that expressions have such values for speakers because they cognize grammars assigning them those values. For if this is true, semantics, syntax, and phonology must be indeterminate, thanks to the indeterminacy of grammar‐cognizing (qua functional‐computational state). So, the fact that a speaker cognizes a grammar cannot explain the determinate character of their language. (shrink)

Dark matter has never been detected, yet it is a key part of the dominant theory of cosmology. An alternative theory, MOND, is empirically equivalent and more successful at making predictions.

Do pregnant mothers have fetuses as parts? According to the “parthood view” they do, while according to the “containment view” they don’t. This paper raises a novel puzzle about pregnancy: if mothers have their fetuses as parts, then wherever there is a pregnant mother, there is also a smaller thinking being that has every part of the mother except for those that overlap with the fetus. This problem resembles a familiar overpopulation puzzle from the personal identity literature, known as the (...) “Thinking Parts Problem”, but it’s not merely a special case of that problem. Rather, the fact that late-term fetuses have a mental life of their own makes the Problem of Pregnant Thinkers, as I will call it, a sui generis and especially recalcitrant problem. (shrink)

This paper is on the metaphysics and normativity of Jewish identity. It starts with a metaphysical question: “Can a Jewish person become non-Jewish?” This question and the related question “What is Jewishness?” are both ambiguous, because the word “Jewish” is ambiguous.

In some of these senses of “Jewish” a Jewish person is always Jewish. (...) In other senses a Jewish person can become non-Jewish. The paper closes with a normative question: Should a person who is Jewish, in the sense of belonging to the Jewish community, become non-Jewish? The paper explains reasons for and against staying in the Jewish community and in doing so highlights a tension, rather than telling anyone how they should identify. (shrink)
