This essay explores problems of consistency among commonsense beliefs about the comparative moral status of animals, fetuses, and human beings congenitally endowed with cognitive capacities and potential no higher than those of higher animals. The possibility of genetic cognitive enhancement exacerbates some of these problems, but also offers new resources for understanding the basis of our moral status as inviolable.

Having encountered landmines in offering a critique of philosophy based on my experience as the mother of a cognitively disabled daughter, I ask, “Should I continue?” I defend the idea that pursuing this project is of a piece with the invisible care labor that is done by people with disabilities and their families. The value of attempting to influence philosophical conceptions of cognitive disability by virtue of this experience is justified by an inextricable relationship between the personal, the (...) political, and the philosophical. If one grants that the “special relationship” between mother and child requires moral recognition, then I need first to make vivid the case that this relationship in the case of a child who lacks some “normal capacities” is indistinguishable from any mother‐child relationship. If this is so, then I believe I can make a case that has as its conclusion that the moral personhood of even the severely cognitively disabled must be granted. Moreover, such recognition, I argue, necessitates the recognition of others who bear no special relationships to the child. (shrink)

This Introduction to the collection of essays surveys the philosophical literature to date with respect to five central questions: justice, care, agency, metaphilosophical issues regarding the language and representation of cognitive disability, and personhood. These themes are discussed in relation to three specific conditions: intellectual and developmental disabilities, Alzheimer's disease, and autism, though the issues raised are relevant to a broad range of cognitive disabilities. The Introduction offers a brief historical overview of the treatment cognitive (...) class='Hi'>disability has received from philosophers, and explains the specific challenges that cognitive disability poses to philosophy. In briefly summarizing the essays in the collection, it highlights the distinctive contributions the collection makes to ethics, political philosophy, bioethics, and the philosophy of disability. We hope that the richness of the topics explored by these essays will be a spur to further investigation. (shrink)

Many theories of moral status that are intended to ground pro-choice views on abortion tie full moral status to advanced cognitive capabilities. Extant accounts of this kind are inconsistent with the intuition that the profoundly cognitively disabled have full moral status. This paper improves upon these extant accounts by combining an anti-luck condition with Steinbock’s stratification of moral status into two levels. On the resulting view, a being has full moral status if and only if she has moral status (...) and has had advanced cognitive capacities, has the potential to develop such capacities, or would have had such capacities were it not for luck. I argue that modal accounts of luck provide a non-speciesist basis for attributing the lack of advanced cognitive capacities in humans to luck without doing the same for non-human animals. (shrink)

Since Darwin, the idea of psychological continuity between humans and other animals has dominated theory and research in investigating the minds of other species. Indeed, the field of comparative psychology was founded on two assumptions. First, it was assumed that introspection could provide humans with reliable knowledge about the causal connection between specific mental states and specific behaviors. Second, it was assumed that in those cases in which other species exhibited behaviors similar to our own, similar psychological causes were at (...) work. In this paper. we show how this argument by analogy is flowed with respect to the case of second-order mental states. As a test case, we focus on the question of how other species conceive of visual attention, and in particular whether chimpanzees interpret seeing as a mentalistic event involving internal states of perception, attention, and belief. We conclude that chimpanzees do not reason about seeing in this manner, and indeed, there is considerable reason to suppose that they do not harbor representations of mental states in general. We propose a reinterpretation model in which the majority of the rich social behaviors that humans and other primates share in common emerged long before the human lineage evolved the psychological means of interpreting those behaviors in mentalistic terms. Although humans, chimpanzees, and most other species may be said to possess mental states, humans alone may have evolved a cognitive specialization for reasoning about such states. (shrink)

Philosophers often enroll disabled bodies and minds as objects of thought in their arguments from marginal cases and in thought experiments: for example, arguments for animal ethics use cognitively disabled people as a contrast case, and Merleau-Ponty uses a blind man with a cane as an exemplar of the relationship of technology to the human, of how technology mediates. However, these philosophers enroll disabled people without engaging significantly in any way with disabled people themselves. Instead, disabled people are treated in (...) philosophy as literal objects—and in many cases, as less than human. (This sense of a categorical difference between disabled and nondisabled people is becoming especially clear during the Covid-19 pandemic, as I write this article.) Philosophical reflection thus makes assumptions—often wrong—about disabled people’s lives, experiences, and relationships to technology. Outside of philosophy as well as in, disabled people are not regarded as experts about our own experiences and lives; our testimony is paternalistically written over. We need better consideration of disabled people as people as we consider the future. Lack of disabled people’s points of view in philosophy colors—and sometimes invalidates—views of technological change. (shrink)

Most theists accept an anthropomorphic view of the divine: a God whose cognition and incarnate embodiment closely resembles human cognition and human embodiment. Most theists also accept an Anselmian view of God on which God has the maximal set of ontological (including moral) perfections. This chapter defends the view that Anselmianism entails that the anthropomorphic view of God is false and that some nonhuman animal is divine. Two arguments are given for this position, which we can call zootheism. The first (...) argument, the Power Argument, claims that because nonhuman animals have moral interests, maximal fairness entails a share in power over those interests. This, in turn, entails a direct share of power within the Godhead, which entails that some nonhuman animal is divine. The second argument, the Incarnation Argument, hues closely to Christian arguments for an incarnation: because God loves us, God will share in our suffering and will pursue non-privileged kinds of incarnate embodiments. This naturally motivates incarnating as a nonhuman animal, particularly given the historically privileged status of humans. Moreover, maximal fairness and maximal love entail that God also pre-existed as a nonhuman animal. Thus, God is, and always was, a nonhuman animal. (shrink)

Philosophers struggle to explain why human beings with deep cognitive impairments have a higher moral status than certain non-human animals. Modal personism promises to solve this problem. It claims that humans who lack the capacities of “personhood” and the potential to develop them nonetheless could have been persons. I argue that modal personism has poor prospects because it's hard to see how we could offer a plausible account of modal personhood. I search for an adequate understanding of modal personhood (...) by considering existing accounts and sketching new ones. But each account fails, either because it objectionably excludes some deeply cognitively impaired humans from the class of modal persons or because it makes modal personhood doubtfully relevant to moral status. And the modal personist cannot solve this problem by appealing to the misfortune suffered by modal persons. (shrink)

Narrative philosophy is the Australian philosopher Raimond Gaita’s answer to the question of how to philosophize in a manner that directly informs efforts to answer the classic philosophical question of ‘how best to live’. Gaita claims, provocatively, that getting the world in view in a manner relevant to arriving at an answer involves challenges that, far from being merely theoretical, are such that we can only meet them by working on ourselves or, alternately, by reshaping our sense of what matters. (...) A productive philosophical intervention would thus need to be in the business of directing our attitudes and would have to have the hallmark of literary discourse or “narrative.” This chapter lays out Gaita’s case for thinking that we need narrative philosophy, and it discusses some of Gaita’s efforts to present us with such a philosophy, specifically in relation to ethical thought about human-animal relations. An important virtue of Gaita’s approach is that it equips us to overcome the philosophically influential, but morally questionable, idea of tension between the moral standing of animals and the moral standing of severely cognitively disabled human beings.

A beautifully written, deeply provocative inquiry into the intersection between animal and disability liberation--the debut of an important new social critic How much of what we understand of ourselves as "human" depends on our physical and mental abilities--how we move (or cannot move) in and interact with the world? And how much does our definition of "human" depend on its difference from "animal"? Drawing on her own experiences as a disabled person, a disability activist, and an animal advocate, (...) author Sunaura Taylor persuades us to think deeply, and sometimes uncomfortably, about what divides the human from the animal, the disabled from the nondisabled--and what it might mean to break down those divisions, to claim the animal and the vulnerable in ourselves, in a process she calls "cripping animal ethics." Beasts of Burden suggests that issues of disability and animal justice--which have heretofore primarily been presented in opposition--are in fact deeply entangled. Fusing philosophy, memoir, and science--including factory farming, disability oppression, or our assumptions of human superiority over animals--Taylor draws attention to new worlds of experience and empathy that will open up important avenues of solidarity across species and ability. Beasts of Burden is a wonderfully engaging and elegantly written work, both philosophical and personal, by a brilliant debut author. (shrink)

Most democratic countries either limit or deny altogether voting rights for people with cognitive impairments or mental health conditions. Against this weight of legal and practical exclusion, disability advocacy and developments in international human rights law increasingly push in the direction of full voting rights for people with cognitive impairments. Particularly influential has been the adoption by the UN of the Convention on the Rights of Persons with Disabilities in 2007. Article 29 declares that states must ‘ensure (...) that persons with disabilities can effectively and fully participate in political and public life on an equal basis with others, directly or through freely chosen representatives, including the right and opportunity for persons with disabilities to vote and be elected’. This article also argues for the right of all people to vote, including people with cognitive impairments, by adopting a uniquely strategic approach. Firstly, some of the strategic limitations of existing arguments in favour of extending the franchise are highlighted. Most such arguments are flawed because they run the risk of inviting disparaging philosophical commentary which compares disabled people to animals, or because they are based on implausible empirical claims, or because they inadvertently tie the case for voting rights for the disabled to other cases unlikely to ever enjoy widespread acceptance. This article, instead, justifies extending voting rights to all people with cognitive impairments based on a simple cost-benefit analysis that avoids all of these problems. (shrink)

This chapter is about personhood in relation to ethics and to conciliar Christian theology, and how concepts of personhood may discriminate against profoundly cognitively disabled human beings. (By ‘conciliar Christian theology’ I mean the Christian theology that is articulated in, or endorsed by, the first seven ecumenical councils.) -/- I believe we can learn several things about personhood by looking at these two topics together. By examining ancient and medieval concepts of personhood and some modern conceptions of personhood we gain (...) a better grasp of the variety of concepts and what substantive work they were intended to do. By becoming familiar with (part of) the history of concepts of personhood we are better situated to appreciate and judge the theoretical work that these concepts were intended to do and what consequences they have in ethical and theological theorizing. -/- In the first section I tell a select history of moral philosophers theorizing about personhood and discuss these in relation to human beings with profound cognitive disability. I focus on John Locke, Immanuel Kant, and Mary Anne Warren. In the “When Personhood Is Discriminatory” section I argue that concepts of personhood, especially modern concepts of personhood, are typically used in a manner that discriminates against human beings with profound cognitive disabilities. I give two arguments against discriminatory uses of personhood, the Moral Shift Argument and the Argument against Exclusive Personhood. Although the Moral Shift Argument is deductively valid, it probably has little persuasive power over those who do not share the moral belief that profoundly cognitively disabled human beings are equal members of the moral community. However, the Argument against Exclusive Personhood has more argumentative force because it denies the claims that personhood is “self-evident” and that it is “obvious” to everyone. In the following section I survey a select history of concepts of personhood in order to establish the claims that concepts of personhood are not self-evident and are not obvious to everyone. This history of personhood goes back to ancient and medieval Christian theorizing and debating about personhood. It shows that concepts of personhood are not “self-evident” but rather are theoretical posits that are posited in theory construction in order to explain certain putative theological facts. Given that personhood is a theoretical posit and is not “self-evident,” moral philosophers who aim to determine the extent of the moral community on the basis of a supposedly “self-evident” concept of personhood are not justified in doing so. Moreover, given the Argument against Exclusive Personhood, philosophical theologians who wish to articulate models of the Trinity or Incarnation that are consistent with the seven ecumenical councils will find that they, like moral philosophers, are not justified to assume, or to insist on, modern personhood for their models of the Trinity or Incarnation. My overall conclusion, then, is that modern personhood is bad for ethics and unnecessary for conciliar ecumenical Christian theology. (shrink)

Some prominent contemporary ethicists, including Peter Singer and Jeff McMahan, do not consider human beings with profound intellectual disabilities to have the same moral status as “normal” people. They hold that individuals who lack sufficiently sophisticated cognitive abilities have the same moral value as nonhuman animals with similar cognitive capacities, such as pigs or dogs. Their goal—to elevate the moral standing of sentient nonhuman animals—is an admirable one which I share. I argue, however, that their strategy does not, (...) in fact, achieve this goal and that there are better ways to advance it than to attach lesser value to the lives of profoundly intellectually disabled persons.

Many models of cognitive ability and disability rely on the idea of cognition as abstract reasoning processes implemented in the brain. Research in cognitive science, however, emphasizes the way that our cognitive skills are embodied in our more basic capacities for sensing and moving, and the way that tools in the external environment can extend the cognitive abilities of our brains. This chapter addresses the implications of research in embodied cognition and extended cognition for how (...) we think about cognitive impairment and rehabilitation, how cognitive reserve mitigates neural impairment, and the distinction between medical and social models of disability.

From the sixteenth to the eighteenth century, new anatomical investigations of the brain and the nervous system, together with a renewed interest in comparative anatomy, allowed doctors and philosophers to ground their theories on sense perception, the emergence of human intelligence, and the soul/body relationship in modern science. They investigated the anatomical structures and the physiological processes underlying the rise, differentiation, and articulation of human cognitive activities, and looked for the “anatomical roots” of the specificity of human intelligence when (...) compared to other forms of animal sensibility. This edited volume focuses on medical and philosophical debates on human intelligence and animal perception in the early modern age, providing fresh insights into the influence of medical discourse on the rise of modern philosophical anthropology. Contributions from distinguished historians of philosophy and medicine focus on sixteenth-century zoological, psychological, and embryological discourses on man; the impact of mechanism and comparative anatomy on philosophical conceptions of body and soul; and the key status of sensibility in the medical and philosophical enlightenment.

Animal welfare scientists face an acute version of the problem of inductive risk, since they must choose whether to affirm attributions of mental states to animals in advisory contexts, knowing their decisions hold consequences for animal welfare. In such contexts, the burden of proof should be sensitive to the consequences of error, but a framework for setting appropriate burdens of proof is lacking. Through reflection on two cases—pain and cognitive enrichment—I arrive at a tentative framework based on the principle (...) of expected welfare maximization. I then discuss the limitations of this framework and the questions it leaves open. (shrink)

This paper considers the range of possible policy options that are available if we wish to attempt to treat people with cognitive disabilities as equal members of society. It is suggested that the goal of policy should be allow each disabled person to establish a worthwhile place in the world and sets out four policy options: cash compensation, personal enhancement, status enhancement and targeted resource enhancement. The paper argues for the social policy of targeted resource enhancement for individuals with (...) cognitive disabilities, in the form of providing cash with some limits on its use. Taking the example from the UK of ‘self-directed support’ it is argued that such policies can be cost-effective and advance the autonomy of people with cognitive disabilities, especially when compared with current policies of centrally provided services.

Individuals with ‘severe’ cognitive disabilities are primarily discussed in philosophy and bioethics to determine their moral status. In this paper it is argued that theories of moral status have limited relevance to the unjust ways in which people with cognitive disabilities are routinely treated in the actual world, which largely concerns their relegation to an inferior social status. I discuss three possible relationships between moral and social status, demonstrating that determinate answers about the moral status of individuals with (...) ‘severe’ cognitive disabilities are neither necessary nor sufficient for defending the imperative that they be treated as our social equals.

Cognitively disabled individuals have been marginalized by our larger culture; they’ve also been marginalized in philosophical discussions. This paper seeks to begin correcting this situation by examining how assumptions which shape our social interactions and expectations disadvantage individuals with a range of cognitive disabilities. After considering Rubella syndrome and autism in detail, I argue that we have a moral obligation to change how we approach social interactions with cognitively disabled individuals.

Philosophical attention to animals can be found in a wide range of texts throughout the history of philosophy, including discussions of animal classification in Aristotle and Ibn Bâjja, of animal rationality in Porphyry, Chrysippus, Aquinas and Kant, of mental continuity and the nature of the mental in Dharmakīrti, Telesio, Conway, Descartes, Cavendish, and Voltaire, of animal self-consciousness in Ibn Sina, of understanding what others think and feel in Zhuangzi, of animal emotion in Śāntarakṣita and Bentham, and of human cultural uniqueness (...) in Xunzi. In recent years, there has been increased attention to animal minds in philosophical discussions across many areas of metaphysics, epistemology, and value theory. Given that nonhuman animals share some biological and psychological features with humans, and that we share community, land, and other resources, consideration of nonhuman animals has much to contribute to our philosophical activities. -/- Contemporary philosophy of animal minds often also engages with the sciences of animal cognition and behavior. The science of comparative cognition is a thriving area of research, complementing the philosophical study in two ways. For one, philosophers of animal cognition can use claims resulting from animal cognition studies as premises in philosophical discussions. For example, Jacob Beck (2012) relies on pigeons’ abilities to compare quantities to argue for nonconceptual content; Sidney Carls-Diamante (forthcoming) appeals to octopus behavior and physiology to defend embodied cognition; Richard Moore (2016a) refers to ape gestural communication to rethink the requirements for intentional communication; Andrew Barron and Colin Klein (2016) appeal to insect cognition research to defend new theories of consciousness; Sarah Vincent, Rebecca Ring, and Kristin Andrews (2019) cite dolphins’ social practices to argue for the existence of norms that do not require metacognition. -/- In addition, philosophers of animal cognition can examine the epistemology and methods used to justify the claims that arise from the science. Research into animal cognition has resulted in surprising claims about animal capacities, such as sociality in garter snakes (Skinner & Miller 2020), tool-use in ants (Maák et al. 2017), mirror self-recognition in fish (Kohda et al. 2019), empathy in rats (Bartal et al. 2011), social learning in fruit flies (Danchin et al. 2018), episodic memory in dogs (Fugazza et al. 2020), addition and subtraction in bees (Howard et al. 2019). How should we evaluate such claims? -/- Some philosophers have argued that animal cognition research is held to a higher standard than human cognition research, and that scientists working with animals are sometimes asked to solve skeptical problems (Halina 2015). Others have challenged scientific assumptions about the relationship between brain size and intelligence, as well as biases against invertebrates (Mikhalevich & Powell 2020). -/- Animal cognition research challenges philosophers to consider that many capacities and behaviors often assumed to require language, sophisticated technological capacities, or legal systems may in fact be had by other animals who lack these properties. In this way, animal cognition research often surprises us by showing that sophisticated-looking activity can be caused through rather simple mechanisms. -/- 1. What is Animal Cognition? 2.

This chapter contains sections titled: The Case for Restricting the Civil Liberties of the Cognitively Disabled Two Conceptions of Competence Further Topics Editor's Note.

I argue that capabilities approaches are useful in formulating a political theory that takes seriously the needs of persons with severe cognitive disabilities (PSCD). I establish three adequacy criteria for theories of justice that take seriously the needs of PSCD: A) understanding PSCD as oppressed, B) positing a single standard of what is owed to PSCD abled individuals, and C) concern with flourishing as well as political liberty. I claim that conceiving valued capabilities as the end of social distribution (...) may help a political theory to meet these criteria.I posit three further adequacy criteria: D) refusing to see PSCD as less than human, E) valuing moral powers other than practical reason, and F) securing space for care and dependency relationships. I show that how well Elizabeth Anderson and Martha Nussbaum’s capabilities approaches meet these criteria depends on their divergent conceptions of what capabilities are for. I sketch another capabilities approach that might better meet the three latter criteria (inspired by Lawrence Becker and Eva Kittay’s work), that conceives capabilities as for agency and relationship.

This chapter provides a roadmap of ongoing conversations about cognitive disability and moral status. Its aim is to highlight the political stakes of these conversations for advocates for the cognitively disabled while at the same time bringing out how a fundamental point of divergence within the conversations has to do with what count as appropriate methods of ethics. The main divide is between thinkers who take ethical neutrality to be a regulative ideal for doing empirical justice to the (...) lives of people with cognitive disabilities and those who reject this methodological precept as unduly restrictive. What results is a debate between, on the one hand, fans of various familiar forms of moral individualism and Kantian approaches in ethics and, on the other, a range of disability scholars and activists who implicitly or explicitly make use of philosophically more radical methods.

Animal cognition is the study of the minds of animals and the mechanisms by which those minds operate. It touches on and illuminates a wide variety of issues at the foundation of cognition science. The methods developed for its study have broad application, and its theories provide essential links between brain and behavior and between evolution and cognition. Among the foundational issues it addresses are: (1) What do we mean by mind? (2) What role does language play in the mind? (...) (3) What are the cognitive processes that operate during perception and recognition? (4) What is the nature of memory? (5) What is the relation between brain and behavior? (6) How does experience affect behavior? (shrink)

Psychology, according to a standard dictionary definition, is the science of mind and behavior. For a major part of the twentieth century, (nonhuman) animal psychology was on a behavioristic track that explicitly denied the possibility of a science of animal mind. While many comparative psychologists remain wedded to behavioristic methods, they have more recently adopted a cognitive, information-processing approach that does not adhere to the strictures of stimulus-response explanations of animal behavior. Cognitive ethologists are typically willing to go (...) much further than comparative psychologists by adopting folk-psychological terms to explain the behavior of nonhuman animals. This different attitudes of many scientists presupposes a distinction between cognitive and mental state attributions that is not commonly articulated. This paper seeks to understand that distinction. (shrink)

This chapter begins by sketching an account of morally responsible agency and the general conditions under which it may fail. We discuss how far individuals with psychiatric diagnoses may be exempt from morally responsible agency in the way that infants are, with examples drawn from a sample of diagnoses intended to make dierent issues salient. We further discuss a recent proposal that clinicians may hold patients responsible without blaming them for their acts. We also consider cognitively impaired subjects in the (...) light of related issues in moral and political theory, asking whether they have been unjustly excluded from liberal conceptions of political community due to their presumed lack of agency.

What can we infer from numerical cognition about mathematical realism? In this paper, I will consider one aspect of numerical cognition that has received little attention in the literature: the remarkable similarities of numerical cognitive capacities across many animal species. This Invariantism in Numerical Cognition (INC) indicates that mathematics and morality are disanalogous in an important respect: proto-moral beliefs differ substantially between animal species, whereas proto-mathematical beliefs (at least in the animals studied) seem to show more similarities. This makes (...) moral beliefs more susceptible to a contingency challenge from evolution compared to mathematical beliefs, and indicates that mathematical beliefs might be less vulnerable to evolutionary debunking arguments. I will then examine to what extent INC can be used to flesh out a positive case for mathematical realism. Finally, I will review two forms of mathematical realism that are promising in the light of the evolutionary evidence about numerical cognition, ante rem structuralism and Millean empiricism.

This essay explores various philosophical approaches to cognitive disability within feminist philosophy. In doing so, it addresses three broad questions: What positive contributions can feminist philosophy make to the philosophy of cognitive disability? How have feminist philosophers critiqued the presence and absence of cognitive disability in philosophy? And what challenges does cognitive disability pose to feminist philosophy itself? The essay begins with definitions and models of disability and then turns to feminist (...) work on cognitive disability in moral and political philosophy, bioethics, and epistemology. It concludes with some methodological considerations. (shrink)

In this paper, I argue that, contrary to what some critics suggest, political liberalism is not exclusionary with regards to the rights and interests of individuals with cognitive disabilities. I begin by defending four publicly justifiable reasons that are collectively sufficient for the inclusion of members of this group. Briefly, these are the epistemic uncertainty that inevitably exists about individuals’ actual capacities, the political liberal duty to treat parents fairly, the social framework that is required for the fulfilment of (...) parental duties, and the necessity of cultivating certain emotions that are strongly associated with reasonableness. These reasons show why a more inclusive reading of political liberalism is plausible, and how this can be achieved without abandoning or revising the theory’s commitment to public reason, the political conception of the person, and the role of social cooperation. I then turn to the question of what a more inclusive political liberalism would look like. More specifically, I argue that, although it would not require the participation of individuals with cognitive disabilities in the practice of legitimation, it would require their full inclusion in the realm of justice as equal rights-bearers.

Drawing heavily on recent empirical research to update R.M. Hare's two-level utilitarianism and expand Hare's treatment of "intuitive level rules," Gary Varner considers in detail the theory's application to animals while arguing that Hare should have recognized a hierarchy of persons, near-persons, & the merely sentient.

Debates in animal cognition are frequently polarized between the romantic view that some species have human-like causal understanding and the killjoy view that human causal reasoning is unique. These apparently endless debates are often characterized by conceptual confusions and accusations of straw-men positions. What is needed is an account of causal understanding that enables researchers to investigate both similarities and differences in cognitive abilities in an incremental evolutionary framework. Here we outline the ways in which a three-dimensional model of (...) causal understanding fulfills these criteria. We describe how this approach clarifies what is at stake, illuminates recent experiments on both physical and social cognition, and plots a path for productive future research that avoids the romantic/killjoy dichotomy.

People with cognitive disabilities are equal citizens, and law ought to show respect for them as full equals. To do so, law must provide such people with equal entitlements to medical care, housing, and other economic needs. But law must also go further, providing people with disabilities truly equal access to education, even when that is costly and involves considerable change in current methods of instruction. The central theme of this essay is what is required in order to give (...) such people political and civil rights on a basis of genuine equality. (shrink)

Sound comparative psychology and modern evolutionary and developmental biology (often called evo-devo) emphasize powerful effects of developmental conditions on the expression of genetic endowment. Both demand that evolutionary theorists recognize these effects. Instead, Tomasello et al. compares studies of normal human children with studies of chimpanzees reared and maintained in cognitively deprived conditions, while ignoring studies of chimpanzees in cognitively appropriate environments.

People with cognitive disabilities and their advocates often express uneasiness about prenatal testing and the selective termination of pregnancies because the fetus has a cognitively disabling condition. There are high rates of abortion in such circumstances, and new forms of noninvasive prenatal testing (NIPT) have been introduced to improve the detection of genetic conditions. This chapter argues that the feeling of disquiet about prenatal testing and selective termination is justified. Philosophers working in the field of bioethics often offer reassurance (...) that such feelings are unjustified. This chapter shows that such reassurances fail and presents an argument that bias against people with cognitive disability plays a role in prenatal decision-making. Feelings of disquiet are justified because it is justified to object to bias that is otherwise directed at oneself. (shrink)
