Mark Rowlands gives a compelling argument that, if John Rawls's contractarianism is consistently applied, and Rawls's premises fully explained, then we have powerful reasons to believe that representatives behind the Veil of Ignorance should be blind to species membership in the same way that they are blind to economic status and natural talent.1I argue that even if we suppose this to be correct, these agents would not choose the two principles of justice, but instead ones that more closely (...) resemble utilitarian principles.

In the debate about the moral status of human beings at the margins of life, arguments of species membership are often considered to be the least plausible ones. Against this backdrop, this article explores two possible ways to formulate feasible arguments of species membership. The first is an (in the broadest sense of the word) Aristotelian or neo‐Aristotelian argument; the second is an argument from the intrinsic logic of human rights, which Robert Spaemann refers toas a (...) ‘transcendental‐pragmatic’ argument. On these grounds, the article proposes a philosophical justification for an at least moderate speciesism. (shrink)

Theories of social justice are necessarily abstract, reaching beyond the particular and the immediate to the general and the timeless. Yet such theories, addressing the world and its problems, must respond to the real and changing dilemmas of the day. A brilliant work of practical philosophy, Frontiers of Justice is dedicated to this proposition. Taking up three urgent problems of social justice neglected by current theories and thus harder to tackle in practical terms and everyday life, Martha Nussbaum seeks a (...) theory of social justice that can guide us to a richer, more responsive approach to social cooperation. The idea of the social contract--especially as developed in the work of John Rawls--is one of the most powerful approaches to social justice in the Western tradition. But as Nussbaum demonstrates, even Rawls's theory, suggesting a contract for mutual advantage among approximate equals, cannot address questions of social justice posed by unequal parties. How, for instance, can we extend the equal rights of citizenship--education, health care, political rights and liberties--to those with physical and mental disabilities? How can we extend justice and dignified life conditions to all citizens of the world? And how, finally, can we bring our treatment of nonhuman animals into our notions of social justice? Exploring the limitations of the social contract in these three areas, Nussbaum devises an alternative theory based on the idea of capabilities. She helps us to think more clearly about the purposes of political cooperation and the nature of political principles--and to look to a future of greater justice for all. (shrink)

The view that species are individuals, as developed by Ghiselinand Hull, has been touted as explaining the role of type specimens intaxonomy. The kinship of this explanation with the Kripke-Putnam theoryof names has long been recognized. In light of this kinship, however,Hull's account of type specimens can be seen to entail two relatedinscrutability problems – unreasonable limits placed on the natureand extent of biological knowledge. An appreciation for these problemsinvites us to consider the proper relation between metaphysical andepistemological inquires (...) in the philosophy of science. (shrink)

Frontiers of Justice: Disability, Nationality, Species Membership, by Martha Nussbaum, Harvard University Press, 2006. How should we measure human development? The most popular method used to be to focus on wealth and income, as when international development agencies rank countries according to their per capita gross domestic product. Critics, however, have long noted shortcomings with this approach. Consider for example a wealthy person in a wheelchair: her problem is not a financial one, but a lack of access to (...) public spaces. Even if she were to hire porters to carry her in and out of stores and libraries, that would not really address her situation. There is a basic sense of dignity and self-respect that comes with being able to move around on one’s own. Even for a disabled millionaire, that will only be possible when public buildings are wheelchair accessible. To fully grasp what the handicapped need, we have to look beyond purely economic measures of well-being, and take into account the actual capabilities people can exercise in their daily lives. The example of the well-off person in a wheelchair illustrates what Martha Nussbaum calls the capabilities approach to human development. It was first pioneered in economics by Amartya Sen (who came up with the wheelchair example), and Nussbaum has for years been associated with a more philosophical variation, which uses the idea of capabilities to outline basic political principles. In Frontiers of Justice: Disability, Nationality, Species Membership Nussbaum takes this project even further, and applies the capabilities approach to issues of justice involving not only the disabled and the global poor, but animals as well.Yet for a philosophy called the capabilities approach, it is surprising how little theoretical work capabilities do in Nussbaum’s overall account.

Book review of Martha Nussbaum's book Frontiers of Justice.

Not only does a shared expertise in classical philosophy and literature inform the works of Martha Nussbaum and Bernard Williams, each has also written and spoken on contemporary social and political issues. Given such ranges of reference, it is not surprising that their two recent books, Frontiers of Justice, a treatise, and In the Beginning Was the Deed, selected essays, confidently take up fundamental political questions. Yet these books differ in their intentions, organising structures, and discursive strategies, and they have (...) little overlap in topics. What then may be hoped from their juxtaposition? That their moral-political perspectives are strongly anti-utilitarian, somewhat anti-Kantian, and self-professedly liberal are unpromising commonplaces. Their juxtaposition can point, I think, toward an alternative to liberalism that is not anti-liberal. Williams considered himself a ‘critical liberal’. But among his contributions to ‘processes of extension’ of liberalism is enlargement of the category of moral agency to some groups in political contexts. And Nussbaum wants to ‘extend the Rawlsian approach’ to liberalism so as to remain a ‘type of political liberal’. But one of her most important conclusions is that it is ‘easy to extend’ justice as political entitlements to nonhumans. Williams 's move toward nonperson moral agents and Nussbaum's toward nonhuman moral patients do not merely ‘extend’ liberalism but, if taken together, leverage a departure beyond it into postliberalism.

Speciesism, broadly understood as the view that species membership is a morally relevant property, has been a central topic of debate within animal ethics for around 50 years. However, in all this time, animal ethicists have paid relatively scant attention to the nature of species membership itself. This seems potentially regrettable, since species membership's precise nature is presumably highly pertinent to the question of its exact moral relevance. Here, I advocate for a ‘species-focused’ (...) approach to assessing speciesism, arguing that, in debating the merits of speciesism, animal ethicists should (i) centre the nature of species membership, and (ii) consult philosophers of biology. Adherence to this second prescription appears necessary since a lot of what philosophers of biology believe regarding the nature of species membership appears contrary to what many animal ethicists have seemingly assumed.

Michael and has argued that species have intrinsic essences. This paper rebuts Devitt’s arguments, but in so doing it shores up the anti-essentialist consensus in two ways that have more general interest. First, species membership can be explanatory even when species have no essences; that is, Tamsin’s membership of the tiger species can explain her stripyness, without this committing us to any further claim about essential properties of tigers. Second, even the views of (...) class='Hi'>species that appear most congenial to essentialism—namely phenetic and genotypic cluster accounts—do not entail strong forms of intrinsic essentialism. (shrink)

Beneath important ethical questions about the impacts of de-extinct species on ecosystems and the potential harms to individual organisms lies a more fundamental assumption; namely, that the thing being "de-extinct-ed" is indeed a member of previously existing species. This is the ontological assumption: that genetic make-up of the individual is both a necessary and sufficient condition for species membership. Questioning this ontological assumption poses an even more critical challenge for de-extinction. Genes a member of a (...) class='Hi'>species do not make. They represent a mere necessary condition. Sufficiency entails a broad set of ecological connections, inside and out. In this commentary on Kasperbauer’s target article, I argue for the primacy of ontology in the ethical analysis of de-extinction. (shrink)

Metaphilosophy, Volume 53, Issue 1, Page 25-37, January 2022.

Anne Conway rejects the view that creatures are essentially members of any natural kind more specific than the kind 'creature'. That is, she rejects essentialism about species membership. This chapter provides an analysis of one of Anne Conway's arguments against such essentialism, which (as I argue) is drawn from metaethical rather than metaphysical premises. In her view, if a creature's species or kind were inscribed in its essence, that essence would constitute a limit on the creature's potential (...) to participate in the divine good. It is this consideration that ultimately leads her to reject essentialism about species membership. The chapter concludes with an examination of some of the metaethical consequences of Conway's view as well as a lesson it can teach us about ideal adviser accounts of the good. (shrink)

In this paper I take issue with the doctrine that organisms belong of their very essence to the natural kinds (or biological taxa, if these are not kinds) to which they belong. This view holds that any human essentially belongs to the species Homo sapiens, any feline essentially belongs to the cat family, and so on. I survey the various competing views in biological systematics. These offer different explanations for what it is that makes a member of one (...) class='Hi'>species, family, etc. a member of that taxon. Unfortunately, none of them offers an explanation that is compatible with the essentialism in question. (shrink)

The fact that humans have a special relationship to each other insofar as they belong in the same species is often taken to be a morally relevant difference between humans and other animals, one which justifies a greater moral status for all humans, regardless of their individual capacities. I give some reasons why this kind of relationship is not an appropriate ground for differential treatment of humans and nonhumans. I then argue that even if relationships do matter morally (...) class='Hi'>species membership cannot justify a difference in moral status. This has important implications because it removes one barrier to giving animals greater moral status. (shrink)

One seldom-noted consequence of most recent arguments for “animal rights” or against “speciesism” is their inability to provide a justification for differential treatment on the basis of species membership, even in cases of rare or endangered species. I defend the claim that arguments about the moral status of individual animals inadequately deal with this issue, and go on, with the help of several test cases, to reject three traditional analyses of our alleged obligation to protect endangered (...) class='Hi'>species. I conclude (a) that these traditional analyses fail, (b) that there is an important conceptual confusion in any attempt to ascribe value to a species, and (c) that our obligation must ultimately rest on the value---often aesthetic-of individual members of certain species.

There is no question that the constituents of cells and organisms are joined together by the part-whole relation. Genes are part of cells, and cells are part of organisms. Species taxa, however, have traditionally been conceived of, not as wholes with parts, but as classes with members. But why does the relation change abruptly from part-whole to class-membership above the level of organisms? Ghiselin, Hull and others have argued that it doesn't. Cells and organisms are cohesive mereological sums, (...) and since species taxa are like cells and organisms in the relevant respects, they, too, are cohesive mereological sums. I provide further reasons in support of the thesis that species are mereological sums. I argue, moreover, that the advocate of this thesis is committed to a form of pluralism with respect to the species concept. (shrink)

This article characterizes various species concepts in terms of set-theoretic models that license biological inferences and illustrates the logical connections among different species concepts. Species in this construal are abstract models, rather than biological or even tangible entities, and relate to individual organisms via representation, rather than the membership or mereological whole/part relationship. The proposal sheds new light on vexed issues of species and situates them within broader philosophical contexts of model selection, scientific representation, and (...) scientific realism. (shrink)

This article is divided into two main sections. The first discusses “Female Inheritance and the Male Retention Hypothesis.” Permanent groups (groups with no inherent limit on group longevity) exist in several species because over generations members share important interests. Considering the association between cooperation and degree of relatedness, it seems to follow that a collective interest is more likely to be achieved when members show a higher degree of relatedness. I argue that if membership is inherited by only (...) one sex, and this is the female sex, this results in a higher degree of relatedness between group members than when membership is inherited by both sexes, or by males only. Indeed, this is found in the overwhelming majority of species of insects, fish, birds, and mammals living in permanent groups. The (few) exceptions to the rule are briefly discussed. Humans are of special interest because human preindustrial societies tend to show either male or female inheritance. The second section asks, “Do Moralizing Gods Raise Paternity Confidence?” Since males inherit valuable membership in patrilocal/lineal societies, they are expected to be more concerned about the probability of paternity than males in matrilocal/lineal societies. Moral rules, and specifically belief in moralizing gods, are expected to reflect this difference. An analysis of cross-cultural data of preindustrial societies does not refute the hypothesis that moralizing gods are more often found in patrilocal/lineal societies, nor is this hypothesis unambiguously supported.

We defend a realistic attitude towards biological species. We argue that two species are not different species because they differ in intrinsic features, be they phenotypic or genomic, but because they are separated with regard to gene flow. There are no intrinsic species essences. However, there are relational ones. We argue that bearing a gene flow relation to conspecifics may serve as the essence of a species. Our view of the species as a Gene-Flow (...) Community differs from Mayr’s definition of the species as a reproductive community. In a reproductive community, each organism is able to successfully reproduce with each other. However, there are species in which geographically distant organisms lost their ability to successfully reproduce, due to strong genetic adaptations to the respective local environmental conditions. Despite this loss of the ability to mutually reproduce, they are still bound by gene flow via continuous intermediate populations. This replacement of Mayr’s notion of an interbreeding potential as a criterion for species membership has important implications for the treatment of populations in allopatry and sympatry. (shrink)

In the first part, I lay out the central features of McMahan's account of the wrongness of killing and its implications for when it is permissible to kill. In the second part of the essay, I argue that we ought not to accept McMahan's rejection of species membership as having any bearing on whether it is permissible to (...) kill a particular individual, as there are ways of understanding its relevance that are more plausible than McMahan allows.

The species concept is one of the central concepts in biological science. Although modern systematics speculates about the existence of a complex hierarchy of nested taxa, biological species are considered particularly important for the active role they play in evolution. However, neither theoretical biologists nor philosophers of biology have come to an agreement about what a species is. In this chapter, we address two questions pertaining to biological species: (1) are they individuals or universals? and (2) (...) are they bona fide or fiat entities? In section The Species-as-Individuals View, we illustrate the reasons that have led many scholars to support the view that species are individuals. In the next two sections, we show that the relational concepts of species – on which the species-as-individuals view is based – provide neither necessary nor sufficient conditions for species membership. This seriously undermines the species-as-individuals view. In the section A Conceptualist Model for the Metaphysics of Species, we advance the proposal that species are fiat concepts (and thus, universal entities partially dependent on the human mind) carved in a multi-dimensional space representing the properties that the biological organisms possess. The final section concludes. (shrink)

A crucial socio-political challenge for our age is how to rede!ne or extend group membership in such a way that it adequately responds to phenomena related to globalization like the prevalence of migration, the transformation of family and social networks, and changes in the position of the nation state. Two centuries ago Immanuel Kant assumed that international connectedness between humans would inevitably lead to the realization of world citizen rights. Nonetheless, globalization does not just foster cosmopolitanism but simultaneously yields (...) the development of new group boundaries. Group membership is indeed a fundamental issue in political processes, for: “the primary good that we distribute to one another is membership in some human community” – it is within the political community that power is being shared and, if possible, held back from non-members. In sum, it is appropriate to consider group membership a fundamental ingredient of politics and political theory. How group boundaries are drawn is then of only secondary importance. Indeed, Schmitt famously declared that “[e]very religious, moral, economic, ethical, or other antithesis transforms into a political one if it is suffciently strong to group human beings e#ectively according to friend and enemy”. Even though Schmitt’s idea of politics as being constituted by such antithetical groupings is debatable, it is plausible to consider politics among other things as a way of handling intergroup di#erences. Obviously, some of the group-constituting factors are more easily discernable from one’s appearance than others, like race, ethnicity, or gender. As a result, factors like skin color or sexual orientation sometimes carry much political weight even though individuals would rather con!ne these to their private lives and individual identity. Given the potential tension between the political reality of particular groupmembership defnitions and the – individual and political – struggles against those definitions and corresponding attitudes, citizenship and civic behavior becomes a complex issue. As Kymlicka points out, it implies for citizens an additional obligation to non-discrimination regarding those groups: “[t]his extension of non-discrimination from government to civil society is not just a shift in the scale of liberal norms, it also involves a radical extension in the obligations of liberal citizenship”. Unfortunately, empirical research suggests that political intolerance towards other groups “may be the more natural and ‘easy’ position to hold”. Indeed, since development of a virtue of civility or decency regarding other groups is not easy, as it often runs against deeply engrained stereotypes and prejudices, political care for matters like education is justified. Separate schools, for example, may erode children’s motivation to act as citizens, erode their capacity for it and!nally diminish their opportunities to experience transcending their particular group membership and behave as decent citizens. This chapter outlines a possible explanation for such consequences. That explanation will be found to be interdisciplinary in nature, combining insights from political theory and cognitive neuroscience. In doing so, it does not focus on collective action, even though that is a usual focus for political studies. For example, results pertaining to collective political action have demonstrated that the relation between attitudes and overt voting behavior or political participation is not as direct and strong as was hoped for. Several conditions, including the individual’s experiences, self-interest, and relevant social norms, turned out to interfere in the link between his or her attitude and behavior. Important as collective action is, this chapter is concerned with direct interaction between agents and the in$uence of group membership on such interaction – in particular joint action. Although politics does include many forms of action that require no such physical interaction, such physical interaction between individuals remains fundamental to politics – this is the reason why separate schooling may eventually undermine the citizenship of its isolated pupils. This chapter will focus on joint action, de!ned as: “any form of social interaction whereby two or more individuals coordinate their actions in space and time to bring about a change in the environment”. Cognitive neuroscienti!c evidence demonstrates that for such joint action to succeed, the agents have to integrate the actions and expected actions of the other person in their own action plans at several levels of speci!city. Although neuroscienti!c research is necessarily limited to simple forms of action, this concurs with a philosophical analysis of joint action, which I will discuss below. (shrink)

In recent years, the research field of the evolution of art has witnessed contributions from a wide range of disciplines across the "three cultures". In this thesis, I make both a critical review of existing explanations, and try to do elucidate the evolution of art by employing insights, methods and concepts from different disciplines. First, I critically evaluate the evidentiary criteria from standard evolutionary psychology some accounts employ to demonstrate that art qualifies as a human biological adaptation. I argue that (...) these criteria do not suffice to make that claim. Furthermore, I make the case for a cultural evolutionary approach to the arts. One commonly used evidentiary criterion for art as adaptation is the “tight fit” between artnbsp;human cognition, which is interpreted as suggesting that cognition has undergone selection to produce and appreciate art. However, disentangling cultural and genetic evolution allows formulating thenbsp;hypothesis that art has evolved culturally to match human cognition. Second, I observe that in ancient and modern hunter gatherer societies, artistic activities are virtually alwaysnbsp;with ritual. I discuss what this implies for the adaptive significance of art. Specifically, if the arts have culturally evolved in function of ritualistic purposes, their adaptive value has depended on the adaptiveness of ritual. Third, because architecture is characterized by the combination of utilitarian and aesthetic aspects, it is particularly interesting from an evolutionary perspective and therefore I devote special attention to it. Employing the cross-species comparative approach, I investigate two main purposes human architecture has in common with nonhuman animal constructions: protection andnbsp;Based on the phylogenetic approach I establish that protection may have been the primary function of building aptitudes in humannbsp;and that building was later co-opted for signaling purposes. Subsequently, I comparatively evaluate thenbsp;of signaling models in the cultural evolution of architectural aesthetics. Furthermore I combine insights from environmental psychology, niche construction and cultural evolution theory to develop the hypothesis that a function of religious monumental architecture may have been to support nbsp;or even to galvanize nbsp;social learning. Finally, I connect the account I developed to the cognitive science of religion. I complement the frequently held view that religious monumental architecture is a costly signal with the mechanism of sensory exploitation. I attempt to demonstrate that by exploiting thenbsp;response of awe in religious followers, religious monumental architecture promotes and regulates prosocial behavior and creates in them an openness to adopt supernatural beliefs. Fourth, I dealnbsp;the evolution of visual art, paying again special attention to cultural evolution andnbsp;explanatory value of sensory exploitation. I assert that the relatively late appearance of figurative art in the course of human evolution may be attributed to an increase in the number of social learning opportunities within and between human populations at that time. I support this assertion with archaeological data that indicate overall population growth and increased population densities at that time. These demographic changes, I argue, have allowed the retention and accumulation of innovations required for figurative art making. Contrary to previous accounts, I furthermore aim to show that this process doesnbsp;require figurative art to have served adaptive purposes. Employing sensory exploitation, I establish that figurative art could have evolved by exploiting pre-existing biases of evolved psychology. The dominant themes of upper Paleolithic and late stone age figurative art, animals and humans, seem to support this contention. Fifth, I present a number of experimental studies I conducted to verify whether contemporary art experts would have socially learned to resist exploitation of evolved psychology. One aspect ofrsquo;s exploitative power may be that it elicits aesthetic pleasure by pushing “pleasure buttons” that evolved for other purposes. Consequently, spectators may trade-off rewards from indulging in art and biological activities, resulting in less effort being allocated to reproduction. I contend that, while the generalnbsp; may indeed be exploited, experts, who are typically being exposed to high doses of art, may have socially learned to resist exploitation by selectively preferring art from prestigious art contexts. The latter would be in line with the claim that prestige bias may trump content biases of evolved psychology. The results of three experimental studies supportnbsp;contention. I find that laypeople's art appreciation is positively affected by a content bias for attractive faces, mediated by aesthetic pleasure, whereas experts' appreciation is positively affected by prestige and mediated by admiration for the artist. Moreover, experts confer lower appreciation to attractive compared to moderately attractive content, which is consistentnbsp;the contention that expertise and the use of prestige are associatednbsp;resistance against beautiful content that exploits evolved preferences. This research thus suggests that expertise moderates content and context biases, which may be of relevance to an ongoing debate about their relative importance as drivers of cultural evolution. In addition, this study provides a tentative but novel explanation for the fact, famously established by philosopher Arthur Danto, that beauty lost its central position in Western art during the 20th century. However my findings cannot exclude alternative explanations for the fact that art expert appreciation deviates from evolved aesthetic preferences. Further research may experimentally assess the role of prestige bias and resistance as drivers of this deviation versus other, previously suggested, potential processes. For example, preferences of experts may deviate on account of the fact that art serves as a badge of elite group membership and thus expert art appreciation as a means to distinguish oneself from the masses. Alternatively, art experts may seek intellectual challenges instead of pushing pleasure buttons. Future research may experimentally verify the respective roles of these different hypothesized mechanisms. In addition, it may be investigated how insights from sexual selection research may help elucidating the different processes at play in cultural evolution and particularly in the cultural evolution of art appreciation, given the commonalities between sexual selection and cultural selection models.

Modal conventionalism is the view that two crucial forms of sameness are mind-dependent. There is no phenomenon of sameness in kind, on this view, except in virtue of our conventions for individuating nature’s kinds; there is no phenomenon of numerical sameness across time, for an individual member of some natural kind, except in virtue of our conventions for individuating such members.1 Modal conventionalism has its realist opponents. These opponents have argued, following Kripke’s lead more than thirty years ago (Kripke 1972), (...) that the boundaries of at least many of nature’s kinds are carved out by nature itself, and not by our classifi catory practices (e.g., Millikan 2000: passim, e.g., pp. 25 and 72). But they have not generally argued, with anything approaching the same vigor, that modal conventionalism is wrong in its other main claim. They have not in general argued that the world-given connections among properties, that make those properties mind-independently be membership conditions for some natural kind, at the same time make those properties mind-independently be persistence conditions for the members of the kind—properties the departure of which constitutes a ceasing-to-exist for the object that formerly had them. On the contrary, opponents of modal conventionalism have.. (shrink)

Many philosophers have refused to recognize Chinese traditions as genuinely philosophical. The conceptual foundations of these exclusionary efforts appear in Aristotle’s dividing philosophy from rhetoric, then associating philosophy with truth, and rhetoric with metaphor. The Chinese have frequently been defined as metaphorical thinkers, in contrast with the logical, scientific, or literal pursuits of Occidental traditions. Because metaphor is classed with rhetoric, and Chinese was associated with metaphor, critics had a way to say that the Chinese weren’t participating in philia-sophia as (...) rational inquiry into truth. I draw on two strands of 20th century philosophy to move us beyond this exclusionary framing: conceptual metaphor theory (CMT) and Gadamerian hermeneutics. Together these point to a conception of truth that welcomes Chinese traditions and suggests a fusion of horizons that introduces new metaphors for thinking about the role of philosophy. We can see philosophy as a subdiscipline of the more capacious and equally honorable discipline of hao-xue (好學), love of learning. This points us towards a new way forward for global philosophy—away from the thorny issues of access to sophia and towards a conception of hao-xue as the highest of human aims. We can shift the burden of membership qualifications and ask, does the west have hao-xue? As we’ll see, the west, particularly through the influence of Socrates, does have hao-xue, and we can rejoice that philosophy is welcomed into the big tent and can find its rightful place as a subdiscipline of the hallowed human endeavor to love learning.

The literature on the epistemology of ignorance already discusses how certain forms of discrimination, such as racism and sexism, are perpetuated by the ignorance of individuals and groups. However, little attention has been given to how speciesism—a form of discrimination on the basis of species membership—is sustained through ignorance_._ Of the few animal ethicists who explicitly discuss ignorance, none have related this concept to speciesism as a form of discrimination. However, it is crucial to explore this connection, I (...) argue, as ignorance is both an integral part of the injustice done to animals as well as an obstacle to improving their treatment. In order to adequately criticize sustained structural speciesism and injustices towards animals, I develop an epistemological account of ‘speciesist ignorance’. I begin by defining and distinguishing between individual and group-based accounts of speciesist ignorance. I argue that humans, taken as a group, enjoy a position of privilege, which allows them to comfortably remain ignorant of their participation in collective wrongdoings towards animals. Additionally, I point out that speciesist ignorance is structurally encouraged and thereby maintains the dominant view that the human-animal-relationship, as it stands, is just. In sum, this article lays the groundwork for a social epistemology of speciesist ignorance. In particular, it informs further debate about individual and institutional epistemic duties to inquire into speciesism and to inform the public, about the moral culpability of ignorant actions, and about effective animal advocacy and policy which actively rejects speciesist ignorance.

The term ‘speciesism’ was once coined to name discrimination against nonhuman animals as well as the bias that such discrimination expresses. It has sparked a debate on criteria for being morally considerable and the relative significance of human and nonhuman animals’ interests. Many defenses of the preferential consideration of humans have come with a denial of the normative meaning of the term ‘speciesism’ itself. In fact, defenders of the moral relevance of species membership and their critics alike have (...) often used ‘speciesism’ as a merely descriptive technical term for classifying positions in normative ethics. This paper argues that this terminological choice severely impoverishes our ethical vocabulary and moral conceptual scheme. It obscures the considerable common ground among theorists with differing views on the relevance of various properties for moral consideration. It is often overlooked that even most defenders of the preferential treatment of one’s fellow species members have good reason to hold on to the normative notion that ‘speciesism’ was originally meant to be. Two distinct types of concepts are involved when differential treatment along species lines is addressed in a normative and a descriptive way, respectively. The term ‘speciesism’ should be reserved for the normative concept and kept apart from the descriptive term ‘speciescentrism.’ Attempts to redefine speciesism as something that is not wrong by definition are shown to be epistemically and morally harmful for the same reasons attempts to redefine racism and sexism in this way are.

If asked to explain why the Golds’ treatment of other colors in Red Rising is wrong, it is tempting to say something like “they are all human beings, and it is wrong to treat humans in this way!” In this essay, I’ll argue that this simple answer is considerably complicated by the fact that the different colors might not be members of the same biological species, and it is in fact unclear whether any of them are the same (...) class='Hi'>species as current humans. Explaining why exactly this is so will lead us to an exploration the long-running debate in biology and philosophy over what exactly it means for two organisms to be “members of the same species.” I’ll begin by discussing the biological essentialism of Aristotle and his followers, who held that an individual organism’s species was determined by essence. One can easily imagine that the Golds might find this attractive, since it would suggest that their “superior” mental and physical capacities made them a different (and probably “higher”) species of humanity than the other colors. Unfortunately for Aristotle, this turns out to be inconsistent with Charles Darwin’s account of evolution by natural selection. This development has led many modern biologists and philosophers of biology to conceptualize species not as an abstract “form” that serves to classify organisms, but rather as a concrete collection of organisms relatively close to each other in space and time. In contrast to biological essentialism, this view of “species as concrete individual” might seem to support the Reds’ claim to the “same species” as the Gold, since they are both part of the same overarching society. Next, I’ll consider how we might tell where one species “ends” and another one “begins.” As it turns out, biologists have many ways of answering his question, each of which makes different judgments about the species of Red Rising’s characters. So, for example, the “Biological Species Concept” bases judgements about species membership on the ability to produce fertile offspring. This concept is far from perfect, however, for reasons that Red Rising makes clear: it doesn’t deal clearly with cases where reproduction is possible but very difficult (a Red and a Gold having a child) or for organisms that do not reproduce sexually (such as Pinks). I’ll then explore a few prominent alternatives to BSC, including both genetically and ecologically based species concepts, and consider their consequences for the society of Red Rising. I’ll conclude by advocating for a “pluralism” about species membership, and will suggest that the people of Red Rising (as well as in the real world) should beware of basing arguments for moral or political equality on the all-too-slippery notion of “shared humanity.” Instead, they should focus on the qualities that make the lives of the individuals (regardless of their species) worth caring about, such as their shared desires to avoid suffering and to lead fulfilling, meaningful lives.

This book has two main concerns. The first is to isolate the fundamental issues that must be resolved if one is to be able to formulate a defensible position on the question of the moral status of abortion. The second is to determine the most plausible answer to that question. With respect to the first question, the author argues that the following issue–most of which are ignored in public debate on the question of abortion–need to be considered. First, can the (...) abortion question be decided without resolving the issue of the moral status of the fetus? Second, is the fact that the fetus belongs to the biologically defined species Homo Sapiens morally significant in itself? Third, what non-potential properties and necessary and/or sufficient to endow something with a right to life? Fourth, do the corresponding potentialities also make it wrong to destroy something? Fifth, does any property that suffices to give something a right to life admit of degrees, and if so, is it morally significant regardless of the extent to which it is present? Sixth, is it morally permissible to refrain from producing additional people who would lead satisfactory lives? And finally, at what point do developing human beings acquire those properties that give something a right to life – at conception, or at some later point? Alternative answers to these central questions are set out and discussed in a detailed way. Some of the issues are difficult, but it is argued that plausible answers can be advanced, and that they support a liberal position on the morality of abortion. (shrink)

For sexual purposes, animals are off limits. But if we regard attributions of species membership as unimportant in familiar ethical contexts, then it may be difficult to explain why this is the case. Someone who is unimpressed by appeals to species membership as a basis for favoring humans over non-humans may remain similarly unimpressed by such appeals when sex becomes an issue. Species barriers may seem to be beside the point. Peter Singer’s attitude toward human (...) sexual relations with non-humans leans heavily in this direction. In a notorious book review where more was perhaps implied than said, Singer advanced the claim that, in the absence of any cruelty or physical harm, sexual relations with non-human animals would not be “an offence to our status and dignity.” And, insofar as we do not regard status and dignity as the main issue here, we may be inclined to agree. However, what follows will lean in the opposite direction to Singer and will argue that once we have set aside any consideration of status and dignity, we will still have significant grounds for ruling out familiar forms of sex with familiar, terrestrial, non-human animals under ordinary circumstances that fall short of the fictionally-extreme. However, the grounds in question turn out to concern something other than species membership simpliciter. (shrink)

In the German legislation on embryo protection, the scope of protection is defined by its membership to the human species and by the embryo’s inherent potential to develop into a born human being. Both criteria refer to well-known bioethical arguments: the argument from species membership and the potentiality argument. With recent progresses in biotechnology it has, however, become possible manipulate the development potential of human embryos and to blur the boundaries between species. Hence, we must (...) ask, whether both criteria (and with them the arguments) can still hold their ground in bioethics and biomedical law. In my article, I argue, that the aforementioned biotechnological techniques do not require to abandon the arguments from species membership and potentiality. There is, however, a need to clarify what the criteria of species membership and inherent potentiality actually refer to in the relevant laws, i. e. the embryo protection law and the stem cell law.

This chapter presents arguments positing that there is an important sense in which it takes more than all of the actual kinds to make a world, contrary to the popular saying that goes “it takes all kinds to make a world.” In a variety of ways, the various species of elementary particles are ideal cases of natural kinds since each belongs to exactly one of these natural kinds and it essentially belongs to that kind. There exists perfect uniformities within (...) each species and sharp distinctions between the species with respect to certain properties. Some of these properties are essential and suffice to give necessary and adequate conditions for species-membership, while others derive from the fundamental properties via exceptionless uniformities with no ceteris paribus escape clauses.

I characterize the main approaches to the moral consideration of children developed in the light of the argument from 'marginal' cases, and develop a more adequate strategy that provides guidance about the moral responsibilities adults have towards children. The first approach discounts the significance of children's potential and makes obligations to all children indirect, dependent upon interests others may have in children being treated well. The next approaches agree that the potential of children is morally considerable, but disagree as to (...) whether and why children with intellectual disabilities are morally considerable. These approaches explore the moral significance of intellectual capacities, species membership, the capacity for welfare, and the interests of others. I argue that relationships characterized by reciprocity of care are morally valuable, that both the potential to be in such relationships and the actuality of being in them are morally valuable, and that many children with significant intellectual disabilities have this potential.

This paper illuminates the explanatory role of vagueness und species membership against the background of scientific developments in recent stem cell research. With the help of the Neo-Aristotelian concept of “life form naturalism” ontologically vague entities such as stem cells, all above induced pluripotent stem cells, could be described as necessary constituents for the correct sorting and naming of natural processes and its bearers. Furthermore this specific assessment allows drawing some important ontological and ethical consequences.

Two perspectives dominate the general attempt to articulate the philosophical foundations of the animal liberation movement. On the one hand there is the utilitarian perspective typified by the work of Peter Singer. Here the morality of our treatment of nonhumans, and for that matter humans, is determined by an overarching concern to maximize a utility function. In Singer’s case this utility function is in some way composite. Singer urges the maximization of objective preference satisfaction and the maximization of pleasure. The (...) scope of these norms is not arbitrarily limited. In the case of the first, all creatures who have preferences or desires are covered. The second includes all those creatures with the capacity to experience pleasure. The maximization of the utility function does not take into account species membership except instrumentally. Moreover it is merely of instrumental concern that this or that individual is treated in this or that way. The treatment of individuals is determined solely by reference to the utility function.

This essay engages the question whether it makes sense to talk about friendship between human beings and robots. Encountering the question of human and robot friendship, many might initially dismiss the possibility of such relationships out of hand. But such dismissals, it seems, based solely on the basis of species membership, are nothing more than unjustifiable speciesism. Mitias’s analysis of friendship is helpful, but makes the conditions for friendship demanding. Nevertheless, his framework implies that human and robot friendships (...) are possible. (shrink)

Stepping back from the above analysis, it is helpful to ask whether the shift to a more individualistic conception of persons carries traction for those who do not share its religious underpinnings. Judeo-Christian personhood was grounded on the idea that all and only human beings are made in the image of God (imago dei); for contemporary secular philosophers, there seems to be no corollary justification for claiming that all and only human beings qualify as persons. Some contemporary Christians, such as (...) Noonan, have sought to defend an exclusive moral status for human beings by arguing that possessing the human genetic code affords the secular underpinnings for such a position. Yet, this proposal was eventually rebuffed as 'speciesist.' 'Speciesism,' a term coined in the 1970s by Ryder and popularized by Singer, is the position that assigning moral standing on the basis of species membership is morally arbitrary. (shrink)

Juxtaposing the continental philosophy of inclusion/exclusion and the cognitive and affective neuroscience of dehumanization, infrahumanization, and rehumanization may inform animal activists’ strategies. Both fields focus upon how we decide who counts and who doesn’t. Decisions over who’s human and who isn’t are not simply about species membership but involve biopolitical value judgments over who we wish to include or exclude. Posthumanists seek to disrupt the biopolitics of inclusion/exclusion, partly to heal ethical and political relations between human and nonhuman (...) animals. Calarco calls this jamming Agamben’s anthropological machine. Bestia Sacer are those designated as included or excluded, moving among zones of humans, nonhuman animals, and things. Cognitive and affective neuroscience describes how mechanisms of inclusion/exclusion function in dehumanization, infrahumanization, and rehumanization. Humans assign varying degrees of humanity to others according to in-group/out-group status in judgments open to manipulation. Investigating how these mechanisms operate in human perceptions of nonhuman animals may inform activist strategies, transforming ethical and political relations between humans and nonhuman animals and end the exclusion of Bestia Sacer.
