In the history of philosophy, the concept of self has been perennially elusive. The philosophical quest to understand the self is rife with phenomenological and metaphysical analyses, often overlooking other kinds of selves present in the biological realm. To systematically explore this question of non-human selves, I categorize the literature on philosophical and biological notions of self into the biogenic, the zoogenic, and the anthropogenic approaches to self. This article attempts to chart the genesis, the continuum, and the lowest bound (...) of the self. Further, I enumerate challenges in developing a biogenic approach to self or taking the concept of self all the way down in the phylogenetic tree. (shrink)

Dignity is traditionally thought to apply to almost all and almost only humans. However, I argue that an account of a distinctly human dignity cannot achieve a coherent and non-arbitrary justification; either it must exclude some humans or include some nonhumans. This conclusion is not as worrying as might be first thought. Rather than attempting to vindicate human dignity, dignity should extend beyond the human, to include a range of nonhuman animals. Not only can we develop a widely inclusive account (...) of dignity by pursuing this route, but we can still defend the three core principles that lie at the heart of contemporary thinking about dignity: that bearers of dignity possess dignity to an equal degree, in virtue of possessing the same intrinsic worth, and that this generates direct and claimable rights. I thus develop an account of dignity that includes nonhuman animals. I argue that the capacity to value most plausibly grounds dignity. This capacity arises from valenced sentience: a being values insofar as they have experiences that matter to them. I then characterise what follows from this. First, I contend that it is only the capacity to value grounds dignity because this produces the most plausible, simplest, and most explanatorily powerful account of dignity. We ought to reject pluralist accounts which assert a sharp distinction between bearers and non-bearers of rational agency, and biocentric accounts which include non-sentient organic entities. Second, I argue this property grounds an account of dignity that is non-hierarchical. There are no degrees of dignity. Instead, all possessors of the capacity to value have the same kind of intrinsic value, and the same equal fundamental right: to consideration of their interest in leading a life of value. Finally, I argue that since the fundamental right is to consideration, moral agents have claimable duties to engage in a deliberative procedure with actionable requirements. Specific rights are instantiations of this general procedure. Certain revisionist conclusions follow on my view, for instance, that nonhumans should be given greater weight and inclusion in a far wider range of cases, but my account is sensitive to the range of different things different beings value, so it does not generate counterintuitive implications. I conclude that dignity extends beyond the human. (shrink)

How does consciousness vary across the animal kingdom? Are some animals ‘more conscious’ than others? This article presents a multidimensional framework for understanding interspecies variation in states of consciousness. The framework distinguishes five key dimensions of variation: perceptual richness, evaluative richness, integration at a time, integration across time, and self-consciousness. For each dimension, existing experiments that bear on it are reviewed and future experiments are suggested. By assessing a given species against each dimension, we can construct a consciousness profile for (...) that species. On this framework, there is no single scale along which species can be ranked as more or less conscious. Rather, each species has its own distinctive consciousness profile. (shrink)

Can animals be agents? Do they want to be free? Can they have meaningful lives? If so, should we change the way we treat them? This paper offers an account of animal agency and of two continuums: between human and nonhuman agency, and between wildness and captivity. It describes how a wide range of human activities impede on animals’ freedom and argues that, in doing so, we deprive a wide range of animals of opportunities to exercise their agency in ways (...) that can give meaning to their lives.

This chapter addresses the extent to which nonhuman animals are conscious. Most important perhaps is what criteria should be used in making such a determination.

Experimenters claim some nonhuman mammals have metacognition. If correct, the results indicate some animal minds are more complex than ordinarily presumed. However, some philosophers argue for a deflationary reading of metacognition experiments, suggesting that the results can be explained in first-order terms. We agree with the deflationary interpretation of the data but we argue that the metacognition research forces the need to recognize a heretofore underappreciated feature in the theory of animal minds, which we call Unity. The disparate mental states (...) of an animal must be unified if deflationary accounts of metacognition are to hold and untoward implications avoided. Furthermore, once Unity is acknowledged, the deflationary interpretation of the experiments reveals an elevated moral standing for the nonhumans in question. (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)

In this article, we develop and defend an account of the normative significance of nonhuman animal agency. In particular, we examine how animals’ agency interests impact upon the moral permissibility of our interactions with them. First, we defend the claim that nonhuman animals sometimes have rights to self-determination. However, unlike typical adult humans, nonhuman animals cannot exercise this right through the giving or withholding of consent. This combination of claims generates a puzzle about the permissibility of our interactions with nonhuman (...) animals. If animals sometimes have rights to self-determination, but lack the capacity to consent, then when, if ever, is it permissible for us to touch them, hold them, bathe them, or confine them? In the second half of the article, we develop a solution to this puzzle. We argue that while we cannot obtain animals’ consent, they can engage in authoritative communications of will through acts of “assent” and “dissent.”. (shrink)

We provide an account of chimpanzee-specific agency within the context of philosophy of action. We do so by showing that chimpanzees are capable of what we call reason-directed action, even though they may be incapable of more full-blown action, which we call reason-considered action. Although chimpanzee agency does not possess all the features of typical adult human agency, chimpanzee agency is evolutionarily responsive to their environment and overlaps considerably with our own. As such, it is an evolved set of capacities (...) for goal-directed behavior, which solves problems that chimpanzees naturally encounter. Thus, it ought not be understood as a deficient instance of human agency. (shrink)

Human‐animal chimeras—creatures composed of a mix of animal and human cells—have come to play an important role in biomedical research, and they raise ethical questions. This article focuses on one particularly difficult set of questions—those related to the moral status of human‐animal chimeras with brains that are partly or wholly composed of human cells. Given the uncertain effects of human‐animal chimera research on chimeric animals’ cognition, it would be prudent to ensure we do not overlook or underestimate their moral status. (...) However, to assess moral status, we first need to determine what kinds of capacities are morally relevant. The standard view holds that it matters, morally, if chimeric animals develop uniquely human cognitive capacities. I argue that this view is mistaken, highlighting three problems with it: that we can think of examples of uniquely human cognitive capacities that are not morally significant, that we can think of examples of morally significant cognitive capacities that are not uniquely human, and that evidence that some cognitive capacity is shared with nonhuman animals does not undermine claims that this capacity is morally significant. We need a better framework for thinking about the moral status of part‐human beings. (shrink)

This paper argues that contemporary philosophical literature on meaning in life has important implications for the debate about our obligations to non-human animals. If animal lives can be meaningful, then practices including factory farming and animal research might be morally worse than ethicists have thought. We argue for two theses about meaning in life: that the best account of meaningful lives must take intentional action to be necessary for meaning—an individual’s life has meaning if and only if the individual acts (...) intentionally in ways that contribute to finally valuable states of affairs; and that this first thesis does not entail that only human lives are meaningful. Because non-human animals can be intentional agents of a certain sort, our account yields the verdict that many animals’ lives can be meaningful. We conclude by considering the moral implications of these theses for common practices involving animals. (shrink)

Does an affirmation of theistic evolution make the task of theodicy impossible? In this article, I will review a number of ancient and contemporary responses to the problem of evil as it concerns animal suffering and suggest a possible way forward which employs the ancient Jewish insight that evil—as resistance to God's will that results in suffering and alienation from God's purposes—precedes the arrival of human beings and already has a firm foothold in the nonhuman animal world long before humans (...) are ever tempted to go astray. This theological intuition is conferred renewed relevance in light of the empirical reality of evolutionary gradualism and continuity and in view of the recent findings of cognitive ethology. Consequently, I suggest that taking biological evolution seriously entails understanding “moral evil” as a prehuman phenomenon that emerges gradually through the actions and intentions of “free creatures” which—as evolutionary history unfolded—increasingly possessed greater levels of freedom and degrees of moral culpability.

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)

Humans are animals; humans are machines. The current academic and popular dialogue on extending the personhood boundary to certain non-human animal species and at the same time to machines/robots reflects a dialectic about how “being human” is defined; about how we perceive our species and ourselves in relation to the environment. While both paths have the potential to improve lives; these improvements differ in substance and in consequence. One route has the potential to broaden the anthropocentric focus within the West (...) and honor interdependence with life systems; while the other affords greater currency to a human-purpose-driven worldview–furthering an unchecked Anthropocene. The broadening of legal personhood rights to life systems is underway with a ruling for dolphins in India; for a river in New Zealand and with Laws of the Rights of Mother Earth in Bolivia. Many philosophers; ethicists; and ethologists define personhood within the confines of the dominant anthropocentric paradigm; yet alternate eco-centric paradigms offer an inclusive model that may help dismantle the artificial wall between humans and nature. In this paper; I explore these eco-centric paradigms and the implications of an associated worldview for human perceptions; self-awareness; communication; narrative; and research. (shrink)
