It remains at best controversial to claim, non-figuratively, that plants are cognitive agents. At the same time, it is taken as trivially true that many animals are cognitive agents, arguably through an implicit or explicit appeal to natural science. Yet, any given definition of cognition implicates at least some further processes, such as perception, action, memory, and learning, which must be observed either behaviorally, psychologically, neuronally, or otherwise physiologically. Crucially, however, for such observations to be intelligible, they must be counted (...) as evidence for some model. These models in turn point to homologies of physiology and behavior that facilitate the attribution of cognition to some non-human animals. But, if one is dealing with a model of animal cognition, it is tautological that only animals can provide evidence, and absurd to claim that plants can. The more substantive claim that, given a general model of cognition, only animals but not plants can provide evidence, must be evaluated on its merits. As evidence mounts that plants meet established criteria of cognition, from physiology to behavior, they continue to be denied entry into the cognitive club. We trace this exclusionary tendency back to Aristotle, and attempt to counter it by drawing on the philosophy of modelling and a range of findings from plant science. Our argument illustrates how a difference in degree between plant and animals is typically mistaken for a difference in kind. (shrink)

This paper challenges some leading views about the conditions under which the ascription of beliefs and desires can make sense of, or provide reasons for, a creature's behavior. I argue that it is unnecessary for behavior to proceed from beliefs and desires according to the principles of logic and decision theory, or even from principles that generally get things right. I also deny that it is necessary for behavior to proceed from principles that, though perhaps subrational, are similar to those (...) that we ourselves use. I then propose some conditions that are considerably weaker, and argue that they fulfill the descriptive and explanatory requirements of intentional ascription. (shrink)

US court decisions guaranteeing life-sustaining care to anencephalic infants have been viewed with disfavor, and sometimes disbelief, by some ethicists who do not believe in the necessity of life-sustaining support for those without cognitive abilities or an independently sustainable future. The distance between these two views – one legal and inclusive, the other medical and specific – seems unbridgeable. This paper reports on a program using multicriterion decision making to define and describe persons in a way which both acknowledges the (...) differences perceived by many as well as those commonalities insisted on in U.S. court decisions. It does this through application of the Analytic Hierarchy Process to a hierarchy of humanness criteria, and secondarily through reference to that concept''s subset, personhood. (shrink)

Cognitive archaeologists attempt to infer the cognitive and cultural features of past hominins and their societies from the material record. This task faces the problem of _minimum necessary competence_: as the most sophisticated thinking of ancient hominins may have been in domains that leave no archaeological signature, it is safest to assume that tool production and use reflects only the lower boundary of cognitive capacities. Cognitive archaeology involves selecting a model from the cognitive sciences and then assessing some aspect of (...) the material record through that lens. We give examples to show that background theoretical commitments in cognitive science that inform those models lead to different minimum necessary competence results. This raises an important question: what principles should guide us in selecting a model from the cognitive sciences? We outline two complementary responses to this question. The first involves using _independent_ lines of evidence to converge on a particular capacity. This can then influence model choice. The second is a broader suggestion. Theoretical diversity is a good thing in science, but is only beneficial over a limited amount of time. According to recent modelling work, one way of limiting diversity is to introduce extreme priors. We argue that having a broad spectrum of views in the philosophy of cognitive science may actually help cognitive archaeologists address the problem of minimum necessary competence. (shrink)

The essay examines Robin Cook’s Coma and Priscille Sibley’s The Promise of Stardust that dramatize the reified and disposable status of the brain-dead patients who are classified as nonpersons. The essay argues that the man-machine entanglement as depicted in the novels constructs a deterritorialized and entangled form of subjectivity that intervenes in the dominant biomedical understanding of personhood and agency that we notionally associate with a conscious mind. The essay concludes its arguments by discussing Alexander Beliaev’s Professor Dowell’s Head which (...) depicts human subjectivity as an essentially embodied and distributive phenomenon and interrogates the Cartesian mind body dualism embedded in the dominant biomedical narratives.

On the basis of two thought experiments, I argue that self-building technologies are possible given our current level of technological progress. We could already use technology to make us instantiate selfhood in a more perfect, complete manner. I then examine possible extensions of this thesis, regarding more radical self-building technologies which might become available in a distant future. I also discuss objections and reservations one might have about this view.

This paper explores the debate between personists, who argue that the concept of a person if of central importance for moral thought, and personists, who argue that the concept of a human being is of greater moral significance. On the one hand, it argues that normative naturalism, the most ambitious defense of the humanist position, fails to identify moral standards with standards of human behavior and thereby fails to undermine the moral significance of personhood. At the same time, it contends (...) that a more focused attention on the morally relevant features of human life may indeed play a crucial role in enhancing our moral understanding. (shrink)

I sketch briefly some of the more influential theories concerned with the moral status of nonhuman animals, highlighting their biological/physiological aspects. I then survey the most prominent empirical research on the physiological and cognitive capacities of nonhuman animals, focusing primarily on sentience, but looking also at a few other morally relevant capacities such as self-awareness, memory, and mindreading. Lastly, I discuss two examples of current animal welfare policy, namely, animals used in industrialized food production and in scientific research. I argue (...) that even the most progressive current welfare policies lag behind, are ignorant of, or arbitrarily disregard the science on sentience and cognition. (shrink)

Can machines be conscious and what would be the ethical implications? This article gives an overview of current robotics approaches toward machine consciousness and considers factors that hamper an understanding of machine consciousness. After addressing the epistemological question of how we would know whether a machine is conscious and discussing potential advantages of potential future machine consciousness, it outlines the role of consciousness for ascribing moral status. As machine consciousness would most probably differ considerably from human consciousness, several complex questions (...) must be addressed, including what forms of machine consciousness would be morally relevant forms of consciousness, and what the ethical implications of morally relevant forms of machine consciousness would be. While admittedly part of this reflection is speculative in nature, it clearly underlines the need for a detailed conceptual analysis of the concept of artificial consciousness and stresses the imperative to avoid building machines with morally relevant forms of consciousness. The article ends with some suggestions for potential future regulation of machine consciousness. (shrink)

The literature of bioethics suffers from two serious problems. (1) Most authors are unable to take seriously both the rights of the great apes and of severely disabled human infants. Rationalism—moral status rests on rational capacities—wrongly assigns a higher moral status to the great apes than to all severely disabled human infants with less rational capacities than the great apes. Anthropocentrism—moral status depends on membership in the human species—falsely grants all humans a higher moral status than the great apes. Animalism—moral (...) status is dependent on the ability to suffer—mistakenly equates the moral status of humans and most animals. (2) The concept person is widely used for justificatory purposes, but it seems that it cannot play such a role. It seems that it is either redundant or unable to play any justificatory role. I argue that we can solve the second problem by understanding person as a thick evaluative concept. This then enables us to justify assigning a higher moral status to the great apes than to simple animals: the great apes are persons. To solve the first problem, I argue that certain severely disabled infants have a higher moral status than the great apes because they are dependent upon human relationships for their well-being. Only very limited abilities are required for such relationships, and the question who is capable of them must be based on thick evaluative concepts. Thus, it turns out that to make progress in bioethics we must assign thick evaluative concepts a central role. (shrink)

Saul Kripke's influential ‘sceptical paradox’ of semantic rule-following alleges that speakers cannot have any justification for using a word one way rather than another. If it is correct, there can be no such thing as meaning anything by a word. I argue that the paradox fails to undermine meaning. Kripke never adequately motivates its excessively strict standard for the justified use of words. The paradox lacks the resources to show that its standard is truly mandatory or that speakers do not (...) frequently satisfy the well-motivated competitor I offer. So the paradox fails. (shrink)

In this paper it is argued that the experimental data on commissurotomy patients provide no grounds for denying the singular personhood of commissurotomy patients. This is because, contrary to most philosophical accounts, there is no “unity of consciousness” discriminating condition for singular personhood that is violated in the case of commissurotomy patients, and because no contradictions arise when singular personhood is ascribed to commissurotomy patients.

In recent philosophy of science there has been much discussion of both pluralism, which embraces scientific terms with multiple meanings, and eliminativism, which rejects such terms. Some recent work focuses on the conditions that legitimize pluralism over eliminativism – the conditions under which such terms are acceptable. Often, this is understood as a matter of encouraging effective communication – the danger of these terms is thought to be equivocation, while the advantage is thought to be the fulfilment of ‘bridging roles’ (...) that facilitate communication between different scientists and specialisms. These theories are geared towards regulating communication between scientists qua scientists. However, this overlooks an important class of harmful equivocation that involves miscommunication between scientists and nonscientists, such as the public or policymakers. To make my case, I use the example of theory of mind, also known as ‘mindreading’ and ‘mentalizing’, and broadly defined as the capacity to attribute mental states to oneself and others. I begin by showing that ‘theory of mind’ has multiple meanings, before showing that this has resulted in harmful equivocations of a sort and in a way not accounted for by previous theories of pluralism and eliminativism.

The Termination Thesis (or “TT”) is the view that people go out of existence when they die. Lots of philosophers seem to believe it. Epicurus, for example, apparently makes use of TT in his efforts to show that it is irrational to fear death. He says, “as long as we exist, death is not with us; but when death comes, then we do not exist.”1 Lucretius says pretty much the same thing, but in many more words and more poetically: “Death (...) therefore to us is nothing, concerns us not a jot, since the nature of the mind is proved to be mortal; . . . when we shall be no more, when there shall have been a separation of body and soul, out of both of which we are each formed into a single being, to us, you may be sure, who then shall be no more, nothing whatever can happen to excite sensation.”.

Many debates in arenas such as bioethics turn on questions regarding the moral status of human beings at various stages of biological development or decline. It is often argued that a human being possesses a fundamental and inviolable moral status insofar as she is a “person”; yet, it is contested whether all or only human beings count as persons. Perhaps there are non-human person, and perhaps not every human being satisfies the definitional criteria for being a person. A further question, (...) which will be the primary focus of this paper, concerns what essential features of personhood endow persons, human or otherwise, with their moral status and the inherent rights they concomitantly possess. A survey of the history of philosophical theorizing on what it means to be a person yields a broad consensus upon the key capacities being rational thought, self-consciousness, and autonomous volition. It is not sufficient, however, simply to cite these capacities, but to explain why these particular capacities bear moral import. A more recent concern has developed regarding the possible future existence of so-called “post-persons” who, due to their enhanced cognitive and emotive capacities, may be morally superior to mere persons and thereby possess a higher moral status. This paper will conclude with an analysis of the extent to which this concern is warranted. (shrink)

Suppose that God exists: what difference would that make to the world? The answer depends on the nature of God and the nature of the world. In this book, William E. Mann argues in one new and sixteen previously published essays for a modern interpretation of a traditional conception of God as a simple, necessarily existing, personal being. Divine simplicity entails that God has no physical composition or temporal stages; that there is in God no distinction between essence and existence; (...) that there is no partitioning of God's mental life into beliefs, desires, and intentions. God is thus a spiritual, eternal being, dependent on nothing else, whose essence is to exist and whose mode of existence is identical with omniscience, omnipotence, and perfectly goodness. In metaphysical contrast, the world is a spatial matrix populated most conspicuously by finite physical objects whose careers proceed sequentially from past to present to future. Mann defends a view according to which the world was created out of nothing and is sustained in existence from moment to moment by God. The differences in metaphysical status between creator and creatures raise questions for which Mann suggests answers. How can God know contingent facts and necessary truths without depending on them? Why is it so easy to overlook God's presence? Why would self-sufficient God create anything? Wouldn't a perfect God create the best world possible? Can God be free? Can we be free if God's power is continuously necessary to sustain us in existence? If God does sustain us, is God an accomplice whenever we sin? Mann responds to the Euthyphro dilemma by arguing for a kind of divine command metaethical theory, whose normative content lays emphasis on love. Given the metaphysical differences between us, how can there be loving relationships between God and creatures? Mann responds by examining the notions of piety and hope. (shrink)

Philosophy of Mind: Classical and Contemporary Readings is a grand tour of writings on these and other perplexing questions about the nature of the mind. The most comprehensive collection of its kind, the book includes sixty-three selections that range from the classical contributions of Descartes to the leading edge of contemporary debates. Extensive sections cover foundational issues, the nature of consciousness, and the (...) nature of mental content. Three of the selections are published here for the first time, while many other articles have been revised especially for this volume. Each section opens with an introduction by the editor. Philosophy of Mind is suitable for students at all levels and also for general readers. (shrink)

In this paper, we take Darwall’s analytical project of the second-person standpoint as the starting point for a naturalistic project about our moral psychology. In his project, Darwall contends that our moral notions constitutively imply the perspective of second-personal interaction, i.e. the interaction of two mutually recognized agents who make and acknowledge claims on one another. This allows him to explain the distinctive purported authority of morality. Yet a naturalized interpretation of it has potential as an account of our moral (...) psychology. We propose a naturalistic interpretation of Darwall’s work to address some of the main issues about our moral psychology. First, we explain why moral norms motivate us; namely, because of these second-personal relations. We provide a naturalized version of this solution. Second, we articulate how intersubjective interactions take place effectively; grounding duties to particular other subjects, and being related to distinctive moral emotions. Third, we address the question of the limits of the moral community, proposing that it comprises all agents capable of second-personal interactions. Finally, we explain the emergence of community norms through intersubjective interaction. Since all group members can adopt alternatively the second-personal stance to each other, demands are sanctioned and recognized in a triangulation process which explains the emergence of group norms.

-/- Human beings are conscious not only of the world around them but also of themselves: their activities, their bodies, and their mental lives. They are, that is, self-conscious (or, equivalently, self-aware). Self-consciousness can be understood as an awareness of oneself. But a self-conscious subject is not just aware of something that merely happens to be themselves, as one is if one sees an old photograph without realising that it is of oneself. Rather a self-conscious subject is aware of themselves (...) as themselves; it is manifest to them that they themselves are the object of awareness. Self-consciousness is a form of consciousness that is paradigmatically expressed in English by the words “I”, “me”, and “my”, terms that each of us uses to refer to ourselves as such. -/- A central topic throughout the history of philosophy—and increasingly so since the seventeenth century—the phenomena surrounding self-consciousness prompt a variety of fundamental philosophical and scientific questions, including its relation to consciousness; its semantic and epistemic features; its realisation in both conceptual and non-conceptual representation; and its connection to our conception of an objective world populated with others like ourselves.

What justifies our holding a person morally responsible for some past action? Why am I justified in having a special prudential concern for some future persons and not others? Why do many of us think that maximizing the good within a single life is perfectly acceptable, but maximizing the good across lives is wrong? In these and other normative questions, it looks like any answer we come up with will have to make an essential reference to personal identity. So, for (...) instance, it seems we are justified in holding X responsible for some past action only if X is identical to the person who performed that action. Further, it seems I am justified in my special concern for some future person only if he will be me. Finally, many of us think that while maximization within a life affects only one person, a metaphysical unity, maximization across lives affects many different, metaphysically distinct, persons, and so the latter is wrong insofar as it ignores this fundamental separateness of persons.

On the phenomenological view, a minimal form of self-consciousness is a constant structural feature of conscious experience. Experience happens for the experiencing subject in an immediate way and as part of this immediacy, it is implicitly marked as my experience. For the phenomenologists, this immediate and first-personal givenness of experiential phenomena must be accounted for in terms of a pre-reflective self-consciousness. In the most basic sense of the term, selfconsciousness is not something that comes about the moment one attentively inspects (...) or reflectively introspects one's experiences, or in the instant of self-recognition of one's image in the mirror, or in the proper use of the first-person pronoun, or in the construction of a self-narrative. Rather, these different kinds of self-consciousness are to be distinguished from the pre-reflective self-consciousness which is present whenever I am living through or undergoing an experience, i.e., whenever I am consciously perceiving the world, whenever I am thinking an occurrent thought, whenever I am feeling sad or happy, thirsty or in pain, and so forth.

There have been monumental advances in the study of the social dimensions of knowledge in the late twentieth and early twenty-first centuries. But it has been common within a wide variety of fields--including social philosophy, cognitive science, epistemology, and the philosophy of science--to approach the social dimensions of knowledge as simply another resource to be utilized or controlled. I call this view, in which other people's epistemic significance are only of instrumental value, manipulationism. I identify manipulationism, trace its manifestations in (...) the aforementioned fields, and explain how to move beyond it. The principal strategy that I employ for moving beyond manipulationism consists of synthesizing enactivism and neo-Kuhnian social epistemology. Specifically, I expand the enactivist concept of participatory sense-making by linking it to recent conceptual innovations in social epistemology, such as the concept of immanent cogent argumentation.

This thesis presents a communicative account of personhood that argues for the inseparability of the metaphysical and the practical concepts of a person. It connects these two concepts by coupling the question “what is a person” with the question "how does one become a person". It argues that participation in social interactions that are characterized by mutual recognition and giving-and-taking reasons implied by the practical concept of a person is in fact an ecological and developmental condition for an entity to (...) possess the kind of characteristics and capacities such as reflexive self-consciousness addressed by the metaphysical concept. The chief theoretical contribution of the dissertation research lies, accordingly, in demonstrating that an adequate metaphysical concept of a person has to make reference to the kind of social processes that are necessary for the emergence and development of the distinguishing attributes of persons among other moving, perceiving, desiring and cognizing agents. Methodologically, it undertakes an original philosophical analysis that is enriched by an interdisciplinary investigation of several notions and insights from semiotics, comparative and developmental psychology, cognitive science and anthropology. The main argument of the thesis is that one becomes a person through internally recreating a social, communicative process; namely, that of dialogical transformation of habits. We find the paradigmatic case of this social process in mutual persuasion. The internalization of this process in the form of an inner dialogue cultivates a social self that is in ongoing communication with the embodied, organismic self of uncritically habituated attitudes, convictions and desires. This inner dialogue can be conceived as a temporally extended process of self-persuasion, which is characterized by an ongoing strive for attaining higher degrees of self-control; that is, for achieving a more coherent alignment between our habits and the kind of person we would like to be. It starts with self-interpretation and self-evaluation, and culminates in the formation of higher-order desires that facilitate habit-change and novel habit formation in accordance with certain social, moral, aesthetical or intellectual categories and norms one comes to endorse. For this reason, self-induced, deliberate habit-change is also a process of appropriation or self-appropriation, through which we strive to cultivate habits of feeling, thinking, acting that we can deem more truly ours. The thesis demonstrates that the capacity for engaging in this kind of self-persuasion consists chiefly in the capacities for metasemiosis, perspective-taking, and for cultivating habits of reflexivity. It explicates how all these capacities have a social origin and ultimately a social function by showing that they all presuppose certain higher-order communicative patterns that arose through an evolutionary and cultural history, and develop through the internal reconstruction of these patterns as cognitive-semiotic processes. The thesis concludes that becoming a kind of being who can engage in self-persuasion, thus a person, consists ultimately in internalizing the patterns of communicative social interactions in the form of an ongoing auto-communication.

As older people begin to develop dementia, we confront ethical questions about when and how to intervene in their increasingly compromised decision-making. The prevailing approach in bioethics to tackling this challenge has been to develop theories of “decision-making capacity” based on the same characteristics that entitle the decisions of moral persons to respect in general. This article argues that this way of thinking about the problem has missed the point. Because the disposition of property is an identity-dependent right, what matters (...) in dementia and decision-making is an individual’s personal identity with their prior self, not their moral personhood. Therefore, in considering when and how we ought to intervene in the decision-making of those with dementia, we must look to the philosophy of personal identity rather than personhood. (shrink)

In this brief, we argue that there is a diversity of ways in which humans (Homo sapiens) are ‘persons’ and there are no non-arbitrary conceptions of ‘personhood’ that can include all humans and exclude all nonhuman animals. To do so we describe and assess the four most prominent conceptions of ‘personhood’ that can be found in the rulings concerning Kiko and Tommy, with particular focus on the most recent decision, Nonhuman Rights Project, Inc v Lavery.

The overall aim of this thesis is to look at some philosophical issues surrounding autonomous systems in society and war. These issues can be divided into three main categories. The first, discussed in papers I and II, concerns ethical issues surrounding the use of autonomous systems – where the focus in this thesis is on military robots. The second issue, discussed in paper III, concerns how to make sure that advanced robots behave ethically adequate. The third issue, discussed in papers (...) IV and V, has to do with agency and responsibility. Another issue, somewhat aside from the philosophical, has to do with coping with future technologies, and developing methods for dealing with potentially disruptive technologies. This is discussed in papers VI and VII. Paper I systemizes some ethical issues surrounding the use of UAVs in war, with the laws of war as a backdrop. It is suggested that the laws of war are too wide and might be interpreted differently depending on which normative moral theory is used. Paper II is about future, more advanced autonomous robots, and whether the use of such robots can undermine the justification for killing in war. The suggestion is that this justification is substantially undermined if robots are used to replace humans to a high extent. Papers I and II both suggest revisions or additions to the laws or war. Paper III provides a discussion on one normative moral theory – ethics of care – connected to care robots. The aim is twofold: first, to provide a plausible and ethically relevant interpretation of the key term care in ethics of care, and second, to discuss whether ethics of care may be a suitable theory to implement in care robots. Paper IV discusses robots connected to agency and responsibility, with a focus on consciousness. The paper has a functionalistic approach, and it is suggested that robots should be considered agents if they can behave as if they are, in a moral Turing test. Paper V is also about robots and agency, but with a focus on free will. The main question is whether robots can have free will in the same sense as we consider humans to have free will when holding them responsible for their actions in a court of law. It is argued that autonomy with respect to norms is crucial for the agency of robots. Paper VI investigates the assessment of socially disruptive technological change. The coevolution of society and potentially disruptive technolgies makes decision-guidance on such technologies difficult. Four basic principles are proposed for such decision guidance, involving interdisciplinary and participatory elements. Paper VII applies the results from paper VI – and a workshop – to autonomous systems, a potentially disruptive technology. A method for dealing with potentially disruptive technolgies is developed in the paper. (shrink)

Ranging from miniaturized biological robots to organoids, multi-cellular engineered living systems (M-CELS) pose complex ethical and societal challenges. Some of these challenges, such as how to best distribute risks and benefits, are likely to arise in the development of any new technology. Other challenges arise specifically because of the particular characteristics of M-CELS. For example, as an engineered living system becomes increasingly complex, it may provoke societal debate about its moral considerability, perhaps necessitating protection from harm or recognition of positive (...) moral and legal rights, particularly if derived from cells of human origin. The use of emergence-based principles in M-CELS development may also create unique challenges, making the technology difficult to fully control or predict in the laboratory as well as in applied medical or environmental settings. In response to these challenges, we argue that the M-CELS community has an obligation to systematically address the ethical and societal aspects of research and to seek input from and accountability to a broad range of stakeholders and publics. As a newly developing field, M-CELS has a significant opportunity to integrate ethically responsible norms and standards into its research and development practices from the start. With the aim of seizing this opportunity, we identify two general kinds of salient ethical issues arising from M-CELS research, and then present a set of commitments to and strategies for addressing these issues. If adopted, these commitments and strategies would help define M-CELS as not only an innovative field, but also as a model for responsible research and engineering. (shrink)

From the legal point of view, "person" is not co-extensive with "human being." Nor is it synonymous with "rational being" or "responsible subject." Much of the confusion surrounding the issue of the firm’s legal personality is due to the tendency to address the matter with only these, all too often conflated, definitions of personhood in mind. On the contrary, when the term "person" is defined in line with its original meaning as "mask" worn in the legal drama, it is easy (...) to see that it is only the capacity to attract legal relations that defines the legal person. This definition, that avoids the undesirable emotional associations and equivocations that often plague the debate, is important for a legally-grounded view of the firm. (shrink)

Many people seem to understand the term 'dignity' as applying to all human persons regardless of their race, creed, sex, or religious beliefs. As to what the concept 'dignity' means is a difficult and complex problem. Is the concept 'dignity' an empty concept, void of meaning? What does it mean when we say that this or that person has dignity? Most of the current philosophical literature has very little to say as to what dignity is. I will argue that what (...) we need to find is a concept of dignity that accounts for both the infinite and the irreplaceable value of the human person. Following Kant and Linda Zagzebski, we can say that to be irreplaceable is to be above all comparison and to be of infinite value is to be above all price. This paper will explore how to understand the two aspects of dignity; infinite and irreplaceable value as being necessary components in understanding our intuitions that we have about human persons having 'dignity'. To show how both aspects of dignity are necessary, this paper will explore intuitions of the irreplaceability and infinite value of human persons by looking at the concrete experiences that we have of friendship and love. We will look at Gabriel Marcel's definition of the human person and methodology to see if we can better understand the irreplaceable aspect of the human person. In the last few pages of this thesis we will see how to metaphysically tie the knot between these two aspects. (shrink)

The American television show Rick and Morty, an animated science fiction sitcom, critiques speciesism in the context of bleak existentialist philosophy. Though the show focuses primarily on human characters, it also depicts various forms of artificial sentience, such as robots or clones, undergoing existential crises. It explicitly effaces any distinction between human sentience and artificial sentience, forcefully treating all sentient life with an equivalent respect (or disrespect). The show also problematizes human speciesism in relationship to terrestrial and extra-terrestrial life.

The concept of natural kind is center stage in the debates about scientific realism. Champions of scientific realism such as Richard Boyd hold that our most developed scientific theories allow us to “cut the world at its joints” (Boyd, 1981, 1984, 1991). In the long run we can disclose natural kinds as nature made them, though as science progresses improvements in theory allow us to revise the extension of natural kind terms.

Collective intentionality is one of the most fundamental notions in social ontology. However, it is often thought to refer to a capacity which does not presuppose the existence of any other social facts. This chapter critically examines this view from the perspective of one specific theory of collective intentionality, the theory of Margaret Gilbert. On the basis of Gilbert’s arguments, the chapter claims that collective intentionality is a highly contingent achievement of complex social practices and, thus, not a basic social (...) phenomenon. The argument proceeds in three steps. First, Gilbert’s thesis that certain kinds of collective intentionality presuppose joint normative commitments is introduced. Second, it is argued that, on this view, individual commitments can only constitute the relevant kinds of collective intentional states if there are socially shared “principles of membership” that connect the force of individual commitments to a shared content. Third, it is shown that strong collective intentionality depends on the practical acceptance of shared norms and on the establishment of authority relations through mutual recognition. (shrink)

Most philosophical accounts of human rights accept that all persons have human rights. Typically, ‘personhood’ is understood as unitary and binary. It is unitary because there is generally supposed to be a single threshold property required for personhood. It is binary because it is all-or-nothing: you are either a person or you are not. A difficulty with binary views is that there will typically be subjects, like children and those with dementia, who do not meet the threshold, and so who (...) are not persons with human rights, on these accounts. It is consequently unclear how we ought to treat these subjects. This is the problem of marginal cases. I argue that we cannot resolve the problem of marginal cases if we accept a unitary, binary view of personhood. Instead, I develop a new non-binary personhood account of human rights, and defend two main claims. First, there are many, scalar properties, the having of which are conducive to personhood. Second, different subjects have different human rights depending on which of these properties they have, and what threats apply to them. On my view, and contra most existing accounts, most marginal cases have some degree of personhood and are entitled to some human rights. (shrink)

Machine ethics is a field of applied ethics that has grown rapidly in the last decade. Increasingly advanced autonomous robots have expanded the focus of machine ethics from issues regarding the ethical development and use of technology by humans to a focus on ethical dimensions of the machines themselves. This thesis contains two essays, both about robots in some sense, representing these different perspectives of machine ethics. The first essay, “Is it Morally Right to use UAVs in War?” concerns an (...) example of robots today, namely the unmanned aerial vehicles used in war, and the ethics surrounding the use of such robots. In this essay it is argued that UAVs might affect how the laws of war are interpreted, and that there might be need for additional rules surrounding the use of UAVs. This represents the more traditional approach of machine ethics, focusing on the decisions of humans regarding the use of such robots. The second essay, “The Functional Morality of Robots”, concerns the robots of the future – the potential moral agency of robots. The suggestion in this essay is that robots should be considered moral agents if they can pass a moral version of the Turing Test. This represents the new focus of machine ethics: machine morality, or more precisely, machine agency. (shrink)
