When a woman or girl finds herself pregnant, is it morally permissible for her to end that pregnancy? One dominant tradition says “no”; its close cousin says “rarely” - exceptions may be made where the burdens on the individual girl or woman are exceptionally dire, or, for some, when the pregnancy results from rape. On both views, though, there is an enormous presumption against aborting, for abortion involves the destruction of something we have no right to destroy. Those who reject (...) this claim, it is said, do so by denying the dignity of early human life - and imperiling their own. I think these views are deeply flawed. They are, I believe, based on a problematic conception of how we should value early human life; more than that, they are based on a profoundly misleading view of gestation and a deontically crude picture of morality. I believe that early abortion is fully permissible, widely decent, and, indeed, can be honorable. This is not, though, because I regard burgeoning human life as “mere tissue”: on the contrary, I think it has a value worthy of special respect. It is, rather, because I believe that the right way to value early human life, and the right way to value what is involved in and at stake with its development, lead to a view that regards abortion as both morally sober and morally permissible. Abortion at later stages of pregnancy becomes, for reasons I shall outline, multiply more complicated; but it is early abortions - say, abortions in the first half of pregnancy - that are most at stake for women.

What is the metaphysical relationship between the fetus/embryo and the pregnant organism? In this paper I apply a substance metaphysics view developed by Barry Smith and Berit Brogaard to argue, on the basis of topological connectedness, that fetuses/embryos are Lady-Parts: part of the maternal organism up until birth. This leaves two options. Either mammalian organisms begin at birth, or we revise our conception of organisms such that mammalian organisms can be part of other mammals. The first option has some advantages: (...) it is numerically neat; aligns with an intuitive picture of organisms as physically distinct individuals; and ties ‘coming into existence’ to a suitably recognisable and important event: birth. But it denies that the fetus survives birth, or that human organisms existed prior to their birth. The second option allows us to recognise that human organisms exist prior to and survive their birth, but at a cost: it leaves the question of when an organism comes into existence unanswered, and demands potentially far-reaching conceptual revision across a range of domains.

The most popular uniting theme in feminist peace literature grounds women's peace work in mothering. I argue if maternal arguments do not address the variety of relationships different races and classes of mothers have to institutional violence and/or the military, then the resulting peace politics can only draw incomplete conclusions about the relationships between maternal work/thinking and peace. To illustrate this I compare two models of mothering: Sara Ruddick's decription of "maternal practice" and Patricia Hill Collins's account of racial-ethnic women's (...) "motherwork.". (shrink)

Are a material object, such as a statue, and its constituting matter, the clay, parts of one another? One wouldn't have thought so, and yet a number of philosophers have argued that they are. I review the arguments for this surprising claim showing how they all fail. I then consider two arguments against the view concluding that there are both pre-theoretical and theoretical considerations for denying that the statue and the clay are mutual parts.

The Human Animal is an extended defense of what its author calls the Biological Approach to personal identity: that you and I are human animals, and that the identity conditions under which we endure are those which apply to us as biological organisms. The somewhat surprising corollary of this view is that no sort of psychological continuity is either necessary or sufficient for a human animal—and thus for us—to persist through time. In challenging the hegemony of Psychological Approaches to personal (...) identity, Olson offers a number of inventive and original arguments which are certain to evoke discussion and debate.

The nature/nurture debate is not dead. Dichotomous views of development still underlie many fundamental debates in the biological and social sciences. Developmental systems theory offers a new conceptual framework with which to resolve such debates. DST views ontogeny as contingent cycles of interaction among a varied set of developmental resources, no one of which controls the process. These factors include DNA, cellular and organismic structure, and social and ecological interactions. DST has excited interest from a wide range of researchers, from (...) molecular biologists to anthropologists, because of its ability to integrate evolutionary theory and other disciplines without falling into traditional oppositions. The book provides historical background to DST, recent theoretical findings on the mechanisms of heredity, applications of the DST framework to behavioral development, implications of DST for the philosophy of biology, and critical reactions to DST.

This is one of the first books in a new series that will publish the very best work in the philosophy of biology. The series will be non-sectarian in character, will extend across the broadest range of topics, and will be genuinely interdisciplinary. The Immune Self is a critical study of immunology from its origins at the end of the nineteenth century to its contemporary formulation. The book offers the first extended philosophical critique of immunology, in which the function of (...) the term 'self' that underlies the structure of current immune theory is analysed. However, this analysis is carefully integrated into a broad survey of the major scientific developments in immunology, a discussion of their historical context, and a review of the conceptual arguments that have moulded this sophisticated modern science.

_Postures of the Mind _was first published in 1985. Minnesota Archive Editions uses digital technology to make long-unavailable books once again accessible, and are published unaltered from the original University of Minnesota Press editions. Annette Baier develops, in these essays, a posture in philosophy of mind and in ethics that grows out of her reading of Hume and the later Wittgenstein, and that challenges several Kantian or analytic articles of faith. She questions the assumption that intellect has authority over all (...) human feelings and traditions; that to recognize order we must recognize universal laws—descriptive or prescriptive; that the essential mental activity is representing; and that mental acts can be analyzed into discrete basic elements, combined according to statable rules of synthesis. In the first group of essays—"Varieties of Mental Postures"—Baier evaluates the positions taken by philosophers ranging from Descartes to Dennett and Davidson. Among her topics are remembering, intending, realizing, caring, representing, changing one's mind, justifying one's actions and feelings, and having conflicting reasons for them. The second group of essays—"Varieties of Moral Postures" - explores the sort of morality we get when all of these capacities become reflective and self-corrective. Some deal with particular moral issues—our treatment of animals, our policies regarding risk to human life, our contractual obligations; others, with more general questions on the role of moral philosophers and the place of moral theory. These essays respond to the theories of Hobbes, Kant, Rawls, and MacIntyre, but Baier's most positive reaction is to David Hume; _Postures of the Mind _ affirms and cultivates his version of a moral reflection that employs feeling and tradition as well as reason.

I sketch here an intuitive picture of repeatable artworks as created types, which are individuated in part by historical paths (re)production. Although attractive, this view has been rejected by a number of authors on the basis of general claims about abstract objects. On consideration, however, these general claims are overgeneralizations, which whilst true of some abstracta, are not true of all abstract objects, and in particular, are not true of created types. The intuitive picture of repeatable artworks as created types (...) is, then, left in place. (shrink)

The title of this book, Adventures of Ideas, bears two meanings, both applicable to the subject-matter.

Darwin’s classic ‘Origin of Species’ (Darwin 1859) described forces of selection acting upon individuals, but there remains a great deal of controversy about what exactly the status and definition of a biological individual is. Recently some authors have argued that the individual is dispensable – that an inability to pin it down is not problematic because little rests on it anyway. The aim of this paper is to show that there is a real problem of biological individuality, and an urgent (...) need to arbitrate over the current plethora of solutions to it. (shrink)

I here argue that Ted Sider's indeterminacy argument against vagueness in quantifiers fails. Sider claims that vagueness entails precisifications, but holds that precisifications of quantifiers cannot be coherently described: they will either deliver the wrong logical form to quantified sentences, or involve a presupposition that contradicts the claim that the quantifier is vague. Assuming (as does Sider) that the “connectedness” of objects can be precisely defined, I present a counter-example to Sider's contention, consisting of a partial, implicit definition of the (...) existential quantifier that in effect sets a given degree of connectedness among the putative parts of an object as a condition upon there being something (in the sense in question) with those parts. I then argue that such an implicit definition, taken together with an “auxiliary logic” (e.g., introduction and elimination rules), proves to function as a precisification in just the same way as paradigmatic precisifications of, e.g., “red”. I also argue that with a quantifier that is stipulated as maximally tolerant as to what mereological sums there are, precisifications can be given in the form of truth-conditions of quantified sentences, rather than by implicit definition.

In this essay, I attempt to provide answers to the following four queries concerning the metaphysics of early human embryogenesis. (1) Following its first cellular fission, is it coherent to claim that one and only one of two “blastomeric” twins of a human zygote is identical with that zygote? (2) Following the fusion of two human pre-embryos, is it coherent to claim that one and only one pre-fusion pre-embryo is identical with that postfusion pre-embryo? (3) Does a live human being (...) come into existence only when its brain comes into existence? (4) At implantation, does a pre-embryo become a mere part of its mother? I argue that either if things have quidditative properties or if criterialism is false, then queries (1) and (2) can be answered in the affirmative; that in light of recent developments in theories of human death and in light of a more “functional” theory of brains, query (3) can be answered in the negative; and that plausible mereological principles require a negative answer to query (4).

The pregnant subject has a unique experience of her body. The dichotomy between self and other, self and world, breaks down. She can experience a positive narcissism and sense of process. Some conceptualizations and practices of contemporary medicine, however, can alienate the pregnant subject from this bodily experience.

The question “What is an organism?”, formerly considered as essential in biology, has now been increasingly replaced by a larger question, “What is a biological individual?”. On the grounds that i) individuation is theory-dependent, and ii) physiology does not offer a theory, biologists and philosophers of biology have claimed that it is the theory of evolution by natural selection which tells us what counts as a biological individual. Here I show that one physiological field, immunology, offers a theory, which makes (...) possible a biological individuation based on physiological grounds. I give a new answer to the question of the individuation of an organism by linking together the evolutionary and the immunological approaches to biological individuation. (shrink)

A property, F, is maximal iff, roughly, large parts of an F are not themselves Fs.' Maximality makes trouble for a recent analysis of intrinsicality by Rae Langton and David Lewis.

Entities of many kinds, not just material things, have been credited with parts. Armstrong , for example, has taken propositions and properties to be parts of their conjunctions, sets to be parts of sets that include them, and geographical regions and events to be parts of regions and events that contain them. The justification for bringing all these diverse relations under a single ‘part–whole’ concept is that they share all or most of the formal features articulated in mereology . But (...) the concept has also prompted an ontological thesis that has been expressed in various ways: that wholes are ‘no ontological addition’ to their parts ; that to list both a whole and its parts is ‘double counting’; and that there is ‘no more’ to a whole than its parts: for example, that there is no more to a conjunction than the conjuncts that are its parts, and whose truth or falsity determines whether it is true or false. For brevity, I shall express the thesis in the last of these ways, as the claim that entities with parts are ‘nothing but’ those parts. (shrink)

When does a human being begin to exist? We argue that it is possible, through a combination of biological fact and philosophical analysis, to provide a definitive answer to this question. We lay down a set of conditions for being a human being, and we determine when, in the course of normal fetal development, these conditions are first satisfied. Issues dealt with along the way include: modes of substance-formation, twinning, the nature of the intra-uterine environment, and the nature of the (...) relation between fetus and mother (connection, parthood, dependence).

ABSTRACTDo physicians have a duty to sustain the pregnancies of women who die during the first or second trimester? Physicians cannot simply assume that the woman would have wished the pregnancy to continue, nor is it clear that the state has any interest in fetal life before viability. The conditions for beneficence‐based duties of fetal rescue will often be unmet, both because sustaining the pregnancy is not always a clear gain to the born child and because it may impose a (...) substantial burden on the benefactor. And duties of special relationship cannot readily be applied in these cases, as it is difficult to see how the relationship between someone who no longer exists and someone who does not yet exist can breed special duties. Further, to draw on Marx's distinction between the architect, who builds purposefully, and the bee, who cannot help what she is doing, I argue that human pregnancy is in a number of respects purposeful, creative, and deliberate, and that postmortem pregnancy, which follows the model of the bee, is a destructive icon that undercuts women's agency.

In this article, I urge that mainstream discussions of abortion are dissatisfying in large part because they proceed in polite abstraction from the distinctive circumstances and meanings of gestation. Such discussions, in fact, apply to abortion conceptual tools that were designed on the premiss that people are physically demarcated, even as gestation is marked by a thorough-going intertwinement. We cannot fully appreciate what is normatively at stake with legally forcing continued gestation, or again how to discuss moral responsibilities to continue (...) gestating, until we appreciate in their own terms the goods and evils distinctive of gestational connection. To underscore the need to explore further the meanings of gestation, I provide two examples of the difference it might make to legal and moral discussions of abortion if we appreciate more fully that gestation is an intimacy.

In this article I examine the proposition that severe cognitive disability is an impediment to moral personhood. Moral personhood, as I understand it here, is articulated in the work of Jeff McMahan as that which confers a special moral status on a person. I rehearse the metaphysical arguments about the nature of personhood that ground McMahan’s claims regarding the moral status of the “congenitally severely mentally retarded” (CSMR for short). These claims, I argue, rest on the view that only intrinsic (...) psychological capacities are relevant to moral personhood: that is, that relational properties are generally not relevant. In addition, McMahan depends on an argument that species membership is irrelevant for moral consideration and a contention that privileging species membership is equivalent to a virulent nationalism (these will be discussed below). In consequence, the CSMR are excluded from moral personhood and their deaths are less significant as their killing is less wrong than that of persons. To throw doubt on McMahan’s conclusions about the moral status and wrongness of killing the CSMR I question the exclusive use of intrinsic properties in the metaphysics of personhood, the dismissal of the moral importance of species membership, and the example of virulent nationalism as an apt analogy. I also have a lot to say about McMahan’s empirical assumptions about the CSMR. (shrink)

Biological species have been treated traditionally as spatiotemporally unrestricted classes. If they are to perform the function which they do in the evolutionary process, they must be spatiotemporally localized individuals, historical entities. Reinterpreting biological species as historical entities solves several important anomalies in biology, in philosophy of biology, and within philosophy itself. It also has important implications for any attempt to present an "evolutionary" analysis of science and for sciences such as anthropology which are devoted to the study of single (...) species.

Most philosophers writing about personal identity in recent years claim that what it takes for us to persist through time is a matter of psychology. In this groundbreaking new book, Eric Olson argues that such approaches face daunting problems, and he defends in their place a radically non-psychological account of personal identity. He defines human beings as biological organisms, and claims that no psychological relation is either sufficient or necessary for an organism to persist. Olson rejects several famous thought-experiments dealing (...) with personal identity. He argues, instead, that one could survive the destruction of all of one's psychological contents and capabilities as long as the human organism remains alive--as long as its vital functions, such as breathing, circulation, and metabolism, continue.

I defend the historical definition of "function" originally given in my Language, Thought and Other Biological Categories (1984a). The definition was not offered in the spirit of conceptual analysis but is more akin to a theoretical definition of "function". A major theme is that nonhistorical analyses of "function" fail to deal adequately with items that are not capable of performing their functions.

L.A. Paul argues that interesting issues for rational choice theory are raised by epistemically transformative experiences: experiences which provide access to knowledge that could not be known without the experience. Consideration of the epistemic effects of pregnancy has important implications for our understanding of epistemically transformative experiences and for debate about the ethics of abortion and applied ethics more generally. Pregnancy is epistemically transformative both in Paul’s narrow sense and in a wider sense: those who have not been pregnant face (...) significant barriers to acquiring the knowledge made accessible through pregnancy. This knowledge is crucial for engaging with the ethics of abortion. The epistemically transformativeWIDE nature of pregnancy may require us to use new methods to try to partially grasp what pregnancy is like such as for example, significant engagement with narrative literature. Because pregnancy is also epistemically transformative in a narrow sense, we need to work out how to engage in ethical reasoning when relevant knowledge is not fully accessible to all. This argument has implications beyond the debate about abortion. Philosophers in many areas of applied ethics will need to work out how to respond appropriately to epistemically transformative experiences. (shrink)

abstract This paper re‐examines some well‐known and commonly accepted arguments for the non‐individuality of the embryo, due mainly to the work of John Harris. The first concerns the alleged non‐differentiation of the embryoblast from the trophoblast. The second concerns monozygotic twinning and the relevance of the primitive streak. The third concerns the totipotency of the cells of the early embryo. I argue that on a proper analysis of both the empirical facts of embryological development, and the metaphysical importance or otherwise (...) of those facts, all three arguments are found wanting. None of them establishes that the embryo is not an individual human being from the moment of conception. (shrink)

What counts as an individual in the living world? What does it mean for a living thing to remain the same through time, while constantly changing? Immunology answers these questions with its theory of "self" and "nonself" which has dominated the field since the 1940s. Thomas Pradeu argues that this theory is inadequate, because immune responses to self constituents and immune tolerance of foreign entities are the rule, not the exception.

What makes a biological entity an individual? Jack Wilson shows that past philosophers have failed to explicate the conditions an entity must satisfy to be a living individual. He explores the reason for this failure and explains why we should limit ourselves to examples involving real organisms rather than thought experiments. This book explores and resolves paradoxes that arise when one applies past notions of individuality to biological examples beyond the conventional range and presents an analysis of identity and persistence. (...) The book's main purpose is to bring together two lines of research, theoretical biology and metaphysics, which have dealt with the same subject in isolation from one another. Wilson explains an alternative theory about biological individuality which solves problems which cannot be addressed by either field alone. He presents a more fine-grained vocabulary of individuation based on diverse kinds of living things, allowing him to clarify previously muddled disputes about individuality in biology. (shrink)

What kind of thing are we? Paul Snowdon's answer is that we are animals, of a sort. This view--'animalism'--may seem obvious but on the whole philosophers have rejected it. Snowdon argues that animalism is a defensible way of thinking about ourselves. Its rejection rests on the tendency when doing philosophy to mistake fantasy for reality.

Why does a baby who is otherwise cognitively similar to an animal such as a dog nevertheless have a higher moral status? We explain the difference in moral status as follows: the baby can, while a dog cannot, participate as a rearee in what we call “person-rearing relationships,” which can transform metaphysically and evaluatively the baby’s activities. The capacity to engage in these transformed activities has the same type of value as the very capacities (i.e., intellectual or emotional sophistication) that (...) explain unimpaired adult humans’ high moral status. We attempt to extend this account to individuals with severe cognitive impairments. (shrink)

Does natural selection act primarily on individual organisms, on groups, on genes, or on whole species? The question of levels of selection - on which biologists and philosophers have long disagreed - is central to evolutionary theory and to the philosophy of biology. Samir Okasha's comprehensive analysis gives a clear account of the philosophical issues at stake in the current debate.
