Previous research in Explainable Artificial Intelligence (XAI) suggests that a main aim of explainability approaches is to satisfy specific interests, goals, expectations, needs, and demands regarding artificial systems (we call these “stakeholders' desiderata”) in a variety of contexts. However, the literature on XAI is vast, spreads out across multiple largely disconnected disciplines, and it often remains unclear how explainability approaches are supposed to achieve the goal of satisfying stakeholders' desiderata. This paper discusses the main classes of stakeholders calling for explainability (...) of artificial systems and reviews their desiderata. We provide a model that explicitly spells out the main concepts and relations necessary to consider and investigate when evaluating, adjusting, choosing, and developing explainability approaches that aim to satisfy stakeholders' desiderata. This model can serve researchers from the variety of different disciplines involved in XAI as a common ground. It emphasizes where there is interdisciplinary potential in the evaluation and the development of explainability approaches. (shrink)

How do we acquire moral obligations to others? The most straightforward cases are those where we acquire obligations as the result of particular actions which we voluntarily perform. If I promise you that I will trim your hedge, I face a moral Obligation to uphold my promise, and in the absence of some morally significant countervailing reason, I should indeed cut your hedge. Moral obligations which arise as a result of wrongdoing, as a function of corrective justice, are typically thought (...) to be of a similar nature. (shrink)

In general, we think that when it comes to the good of another, we respect that person’s will by acting in accordance with what he wills because he wills it. I argue that this is not necessarily true. When it comes to the good of another person, it is possible to disrespect that person’s will while acting in accordance with what he wills because he wills it. Seeing how this is so, I argue, enables us to clarify the distinct roles (...) that the wills of competent and incompetent people should play in third-party deliberations about their welfare.

The exclusion argument is widely thought to put considerable pressure on dualism if not to refute it outright. We argue to the contrary that, whether or not their position is ultimately true, dualists have a plausible response. The response focuses on the notion of ‘distinctness’ as it occurs in the argument: if 'distinctness' is understood one way, the exclusion principle on which the argument is founded can be denied by the dualist; if it is understood another way, the argument is (...) not persuasive.

What is commonly referred to as the Adoption Problem is a challenge to the idea that the principles of logic can be rationally revised. The argument is based on a reconstruction of unpublished work by Saul Kripke. As the reconstruction has it, Kripke extends the scope of Willard van Orman Quine's regress argument against conventionalism to the possibility of adopting new logical principles. In this paper we want to discuss the scope of this challenge. Are all revisions of logic subject (...) to the Adoption Problem? If not, are there significant cases of logical revision that are subject to the Adoption Problem? We will argue that both questions should be answered negatively. (shrink)

Dry earth seems to its inhabitants (our intrinsic duplicates) just as earth seems to us, that is, it seems to them as though there are rivers and lakes and a clear, odorless liquid flowing from their faucets. But, in fact, this is an illusion; there is no such liquid anywhere on the planet. I address two objections to externalism concerning the nature of the concept that is expressed by the word 'water' in the mouths of the inhabitants of dry earth. (...) Gabriel Segal presents a dilemma for the externalist concerning the application conditions of the concept, and Paul Boghossian presents a dilemma for the externalist concerning the complexity of the concept. I show that, in both cases, the externalist may occupy the horn of his choice without departing from either the letter or spirit of externalism. (shrink)

Chenyang Li argues, in an article originally published in Hypatia, that the ethics of care and Confucian ethics constitute similar approaches to ethics. The present paper takes issue with this claim. It is more accurate to view Confucian ethics as a kind of virtue ethics, rather than as a kind of care ethics. In the process of criticizing Li's claim, the distinctiveness of care ethics is defended, against attempts to assimilate it to virtue ethics.

We distinguish and discuss two different accounts of the subject matter of theories of reference, meta-externalism and meta-internalism. We argue that a form of the meta- internalist view, “moderate meta-internalism”, is the most plausible account of the subject matter of theories of reference. In the second part of the paper we explain how this account also helps to answer the questions of what kind of concept reference is, and what role intuitions have in the study of the reference relation.

Wie ist es wohl, eine Fledermaus zu sein? Wäre ein rein physikalisches Duplikat von mir nur ein empfindungsloser Zombie?

Es stellt sich heraus, dass diese seltsamen Gedankenexperimente nicht nur berechtigte, sondern überaus wichtige Instrumente philosophischen Forschens darstellen. (shrink)

What do we owe those with whom we inquire? Presumably, quite a bit. Anything beyond what is necessary to secure knowledge? Yes. In this paper, I argue for a class of ‘zetetic rights.’ These are rights distinctive to participants in group inquiry. Zetetic rights help protect important central interests of inquirers. These include a right to aid, a right against interference, and a right to exert influence over the course of inquiry. Building on arguments by Fricker (2015), I defend these (...) rights, and explore cases of their violation: zetetic wrongings. I argue that zetetic wrongings constitute a distinctive, ubiquitous, and significant form of injustice in our epistemic and zetetic lives. To improve our inquiries and avoid epistemic injustice, we need to contend with zetetic wronging. Making this case helps show that a complete picture of epistemic life must account for the deep influence of our cooperative ties to one another. (shrink)

This paper defends Priorianism, a theory in the philosophy of time which combines three theses: first, that there is a metaphysical distinction between the present time and non-present times; second, that there are temporary propositions, that is, propositions that change in truth-value simpliciter over time; and third, that there is change over time only if there are temporary propositions. Priorianism is accepted by many Presentists, Growing Block Theorists, and Moving Spotlight Theorists. However, it is difficult to defend the view without (...) appealing to premises that those who reject the view find controversial. My aim in this paper is to defend Priorianism in a way that largely avoids appealing to such premises. I do three things: first (Section 1), I describe the component theses of Priorianism and the relations between them. Next (Section 2), I show how Priorians can respond to the argument that the B-theory implies that there are temporary propositions, and therefore satisfies the Priorian condition for there being change over time. Finally (Section 3), I defend the Priorian thesis that there is change over time only if there are temporary propositions against an alternative principle of change defended by Ross Cameron (The Moving Spotlight, 2015).

Realists about possible worlds typically identify possible worlds with abstract objects, such as propositions or properties. However, they face a significant objection due to Lewis (1986), to the effect that there is no way to explain how possible worlds-as-abstract objects represent possibilities. In this paper, I describe a response to this objection on behalf of realists. The response is to identify possible worlds with propositions, but to deny that propositions are abstract objects, or indeed objects at all. Instead, I argue (...) that realists should follow Prior (1971) and others in treating higher-order quantification (e.g. quantification into predicate or sentence position) as a genuine form of quantification in its own right, and so in particular, not to be analysed in terms of first-order quantification over abstract objects. I argue that from this ‘higher-orderist’ perspective, there is a relatively straightforward answer to the question of how possible worlds-as-propositions succeed in representing possibilities.

Possible worlds have found many applications in contemporary philosophy: from theories of possibility and necessity, to accounts of conditionals, to theories of mental and linguistic content, to understanding supervenience relationships, to theories of properties and propositions, among many other applications. Almost as soon as possible worlds started to be used in formal theories in logic, philosophy of language, philosophy of mind, metaphysics, and elsewhere, theorists started to wonder whether impossible worlds should be postulated as well. In many applications, possible worlds (...) face limitations that can be dealt with through postulating impossible worlds as well. This chapter examines some of the uses of impossible worlds, and philosophical challenges theories of impossible worlds face. (shrink)

A common objection to a proposal or theory in political philosophy is that it is not feasible to realise what it calls for. This is commonly taken to be sufficient to reject a proposal or theory: feasibility, on this common view, operates as a straightforward constraint on moral and political theory, whatever is not feasible is simply ruled out. This paper seeks to understand what we mean when we say that some proposal or outcome is or is not feasible. It (...) will argue that no single binary definition can be given. Rather, there is a whole range of possible specifications of the term ‘feasible’, each of which selects a range of facts of the world to hold fixed. No single one of these possible specifications, though, is obviously privileged as giving the appropriate understanding of ‘feasibility’ tout court. The upshot of my account of feasibility, then, will be that the common view of feasibility as a straightforward constraint cannot be maintained: in order to reject a moral theory, it will not be sufficient simply to say that it is not feasible.

According to James Griffin human rights should be grounded in an account of human dignity, based on “normative agency” – the human capacity to choose and pursue a conception of a worthwhile life. In this paper we take up Griffin’s insight that key legitimate human rights are designed to respect and protect this basic capacity, but reject his assumption that normative agency should always and everywhere be understood in a Western way. We argue that “normative agency” is an indeterminate concept (...) that can be differently understood in different cultural contexts and that thinking about human rights in East Asia should be guided by a Griffin-style approach coupled with an account of normative agency with East Asian characteristics. In developing this idea, we contrast our account with recent, moralized conceptions of Confucian dignity and respond to Griffin’s tacit worries about how to concretely implement views like ours in institutional practice.

The counterintuitive implications of law necessitarianism pose a far more serious threat than its proponents recognize. Law necessitarians are committed to scientific essentialism, the thesis that there are metaphysically necessary truths which can be known only a posteriori. The most frequently cited arguments for this position rely on modal intuitions. Rejection of intuition thus threatens to undermine it. I consider ways in which law necessitarians might try to defend scientific essentialism without invoking intuition. I then consider ways in which law (...) necessitarians who accept the general reliability of intuition might try to explain away the intuitions which conflict with their theory. (shrink)

The appearance of consciousness in the universe remains one of the major mysteries unsolved by science or philosophy. Absent an agreed-upon definition of consciousness or even a convenient system to test theories of consciousness, a confusing heterogeneity of theories proliferate. In pursuit of clarifying this complicated discourse, we here interpret various frameworks for the scientific and philosophical study of consciousness through the lens of social insect evolutionary biology. To do so, we first discuss the notion of a forward test versus (...) a reverse test, analogous to the normal and revolutionary phases of the scientific process. Contemporary theories of consciousness are forward tests for consciousness, in that they strive to become a means to classify the level of consciousness of arbitrary states and systems. Yet no such theory of consciousness has earned sufficient confidence such that it might be actually used as a forward test in ambiguous settings. What is needed now is thus a legitimate reverse test for theories of consciousness, to provide internal and external calibration of different frameworks. A reverse test for consciousness would ideally look like a method for referencing theories of consciousness to a tractable model system. We introduce the Ant Colony Test as a rigorous reverse test for consciousness. We show that social insect colonies, though disaggregated collectives, fulfill many of the prerequisites for conscious awareness met by humans and honey bee workers. A long lineage of philosophically-neutral neurobehavioral, evolutionary, and ecological studies on social insect colonies can thus be redeployed for the study of consciousness in general. We suggest that the ACT can provide insight into the nature of consciousness, and highlight the ant colony as a model system for ethically performing clarifying experiments about consciousness.

When, if ever, can healthcare provider's lay claim to knowing what is best for their patients? In this paper, I offer a taxonomy of clinical disagreements. The taxonomy, I argue, reveals that healthcare providers often can lay claim to knowing what is best for their patients, but that oftentimes, they cannot do so *as* healthcare providers.

The Significant Interest view entails that even if there were no medical reasons to have access to genetic knowledge, there would still be reason for prospective parents to use an identity-release donor as opposed to an anonymous donor. This view does not depend on either the idea that genetic knowledge is profoundly prudentially important or that donor-conceived people have a right to genetic knowledge. Rather, it turns on general claims about parents’ obligations to help promote their children’s well-being and the (...) connection between a person’s well-being and the satisfaction of what I call their “worthwhile significant subjective interests.” To put this view simply, the fact that a donor-conceived person—who knows she is donor-conceived—is likely to be very interested in acquiring genetic knowledge gives prospective parents a weighty reason to use an identity-release donor. This is because parents should promote their children’s well-being through the satisfaction of their children’s worthwhile significant interests. (shrink)

When invited to consider the methodology of contemporary metaphysics, quite a number of procedures spring to mind as part of the metaphysician's toolkit. These include: eliciting and relying on intuitions; solving location problems and using “conceptual analysis”; inference to the best theory, both on internal metaphysical grounds and drawing from the theoretical reaches of the sciences; working on topics clearly close to, or even overlapping, those of other areas of inquiry using techniques of those other areas; achieving coherence with other (...) theories developed with other aims; and employing deductive reasoning to yield surprising conclusions. Many of these techniques are associated with significant and growing literatures about their scope, epistemic justification, suitability to different metaphysical problems, and so on. (shrink)

We should not be creating conscious, humanoid agents but an entirely new sort of entity, rather like oracles, with no conscience, no fear of death, no distracting loves and hates.

What is faith? Lara Buchak has done as much as anyone recently to answer our question in a sensible and instructive fashion. As it turns out, her writings reveal two theories of faith, an early one and a later one (or, if you like, two versions of the same theory). In what follows, we aim to do three things. First, we will state and assess Buchak’s early theory, highlighting both its good-making and bad-making features. Second, we will do the same (...) for her later theory, noting improvements on the early one. Third, we will mark various choice points in theorizing about faith, and we will argue for specific choices at those points, culminating in what we regard as a better, alternative theory of faith. Our critical aims, therefore, are ultimately constructive. By theorizing about faith with Lara Buchak, we aim to contribute to our common understanding of what faith is. (shrink)

In discussions about the ethics of enhancement, it is often claimed that the concept of ‘human nature’ has no helpful role to play. There are two ideas behind this thought. The first is that nature, human nature included, is a mixed bag. Some parts of our nature are good for us and some are bad for us. The ‘mixed bag’ idea leads naturally to the second idea, namely that the fact that something is part of our nature is, by itself, (...) normatively inert. The Inert View claims that nothing normative follows from the mere fact that some trait is a part of our nature. If the Inert View is correct, then appeals to the value or importance of human nature in debates about enhancement are indeed misplaced. We argue that the Inert View is wrong, and that a certain concept of human nature – which we refer to as human form – does have an important role to play in debates about enhancement. (shrink)

Although thought experiments were first discovered as a sui generis methodological tool by philosophers of science (most prominently by Ernst Mach), the tool can also be found – even more frequently – in contemporary philosophy. Thought experiments in philosophy and science have a lot in common. However, in this chapter we will concentrate on thought experiments in philosophy only. Their use has been the centre of attention of metaphilosophical discussion in the past decade, and this chapter will provide an overview (...) of the results this discussion has achieved and point out which issues are still open.

Are there any deep or systematic connections between paternalism and people's rights? Perhaps the connection is definitional: part of what makes an action or policy paternalistic is that it violates a right. Or perhaps the connection is normative: paternalism is (always? often? only sometimes?) morally problematic because it violates people's rights (even if we don't define "paternalism" in terms of a rights violation). My main goal in this paper is to argue for the normative connection. Part of the task will (...) be to explain exactly what the normative connection is. That will involve answering the questions embedded in the claim as well as offering an account of the right(s) that is (are) connected to paternalism's normative status. (shrink)

This paper is a response to two sets of published criticisms of the 'Reasons as Evidence’ thesis concerning normative reasons, proposed and defended in earlier papers. According to this thesis, a fact is a normative reason for an agent to Φ just in case this fact is evidence that this agent ought to Φ. John Broome and John Brunero have presented a number of challenging criticisms of this thesis which focus, for the most part, on problems that it appears to (...) confront when it comes to the topic of the weighing of reasons. Our paper responds to all of the criticisms that these critics have provided, shedding fresh light on this interesting topic in the process. (shrink)

According to evidentialism, a belief is propositionally justified just in case it fits one’s evidence. A fully developed evidentialist theory of justification will require an account of the evidential fit relation. Some evidentialists have embraced an explanationist account of this relation. Some of these accounts, such as Kevin McCain’s, place an awareness requirement on evidential fit. That is, they claim that a proposition, p, fits a subject’s evidence, e, only if the subject is aware of the explanatory connection between p (...) and e. I argue by way of example that this version of explanationism fails. As a result, I suggest a friendly revision of explanationism that excludes an awareness condition. Finally, I field some objections to my version of explanationism. (shrink)

Berkeley argues that claims about divine predication (e.g., God is wise or exists) should be understood literally rather than analogically, because like all spirits (i.e., causes), God is intelligible only in terms of the extent of his effects. By focusing on the harmony and order of nature, Berkeley thus unites his view of God with his doctrines of mind, force, grace, and power, and avoids challenges to religious claims that are raised by appeals to analogy. The essay concludes by showing (...) how a letter, supposedly by Berkeley, to Peter Browne ("discovered" in 1969 by Berman and Pittion) is, in fact, by John Jackson (1686-1763), controversial theologian and friend of Samuel Clarke.

Since nothing about God is passive, and the perception of pain is inherently passive, then it seems that God does not know what it is like to experience pain. Nor would he be able to cause us to experience pain, for his experience would then be a sensation (which would require God to have senses, which he does not). My suggestion is that Berkeley avoids this situation by describing how God knows about pain “among other things” (i.e. as something whose (...) identity is intelligible in terms of the integrated network of things). This avoids having to assume that God has ideas (including pain) apart from his willing that there be perceivers who have specific ideas that are in harmony or not in harmony with one another.

Pluralistic ignorance is a social-psychological phenomenon in which an agent believes that their attitudes, feelings, and beliefs are different from those of others, despite the fact that their public behavior is identical. I argue that agents in standard cases of pluralistic ignorance are epistemically irrational. I accomplish this, first, by rebutting a recent argument for the rationality of pluralistic ignorance. Next, I offer a defeat-based argument against the epistemic rationality of pluralistic ignorance. Third, I examine a type of case in (...) which the pluralistically ignorant agent's belief is irrational, despite the fact that this belief lacks a defeater. Finally, I consider instances of pluralistically ignorant agents whose beliefs are not irrational, but explain why such cases are not problematic for my main thesis. This critical discussion allows me to offer an important amendment to an extant account of pluralistic ignorance. (shrink)

Just War Theory (JWT) replaced an older "warrior code," an approach to war that remains poorly understood and dismissively treated in the philosophical literature. This paper builds on recent work on honor to address these deficiencies. By providing a clear, systematic exposition of "Honor War Theory" (HWT), we can make sense of paradigm instances of warrior psychology and behavior, and understand the warrior code as the martial expression of a broader honor-based ethos that conceives of obligation in terms of fair (...) competition for prestige. Far from being a romantic and outmoded approach to war, HWT accounts for current conflicts and predicts moral intuitions that JWT either rejects or cannot comfortably accommodate. So although it is not recommended as a replacement for JWT, there is good reason think that a fully mature, realistic, and yet properly normative theory of war ethics will incorporate a variety of insights from HWT.

Modal ontological arguments are often claimed to be immune to the flqqperfect islandfrqq objection of Gaunilo, because necessary existence does not apply to material, contingent things. But Gaunilo’s strategy can be reformulated: we can speak of non-contingent beings, like quasi-Gods or evil God. The paper is intended to show that we can construct ontological arguments for the existence of such beings, and that those arguments are equally plausible as theistic modal argument. This result does not show that this argument is (...) fallacious, but it shows that it is dialectically ineffective as an argument for theism. (shrink)

In ’Abortion and deprivation: a reply to Marquis’, Anna Christensen contends that Don Marquis’ influential ’future like ours’ argument for the immorality of abortion faces a significant challenge from the Epicurean claim that human beings cannot be harmed by their death. If deprivation requires a subject, then abortion cannot deprive a fetus of a future of value, as no individual exists to be deprived once death has occurred. However, the Epicurean account also implies that the wrongness of murder is also (...) not grounded in the badness of death, which is strongly counterintuitive. There is an alternative: we can save our intuitions by adopting a more moderate Epicurean account such as that proposed by David Hershenov, who grounds the wrongness of killing in the prevention of the benefit of further good life rather than in the badness of death. Hershenov’s account, however, is equally applicable to Marquis’ argument: abortion similarly prevents a fetus from enjoying the benefit of a future like ours. Consequently, we conclude that Christensen’s criticism of Marquis’ argument fails to undermine his reasoning. (shrink)

To say that a philosophical dispute is ‘merely verbal’ seems to be an important diagnosis. If that diagnosis is correct for a particular dispute, then the right thing to do would be to declare that dispute to be over. The topic of what the disputing parties were fighting over was just a pseudo-problem (thus not really a problem), or at least – if there is a sense in which also merely verbal disputes indicate some problem, for example, insufficient clarity of (...) terminology – this problem is not substantial, or not as substantial as the disputing parties believed their problem initially to be. In this paper I will try to clarify what it means if we diagnose that two arguing parties are having a merely verbal dispute. (shrink)

There is a widespread assumption that B-theorists (according to whom there is nothing metaphysically special about the present moment in virtue of which it is present) should interpret the standard tense operators (‘it was the case that’, ‘it will be the case that’) as implicit quantifier-restrictors – so that, for example, an utterance at instant t of the sentence ‘It was the case that there are dinosaurs’ is true just in case there are dinosaurs located at some instant t* earlier (...) than t. However, it is easy to show that this interpretation of the tense operators creates serious problems for B-theorists when combined with certain other relatively uncontroversial B-theoretic assumptions. In this paper, I argue that the best way for B-theorists to respond to these problems is to treat the standard tense operators as redundant when the sentences in their scope are qualitative (i.e. not about any particular individuals).

In their paper “Sixteen Days” Barry Smith and Berit Brogaard try to answer the question: when does a human being begin to exist? In this paper we will address some methodological issues connected with this exercise in ontology. We shall begin by sketching the argument of “Sixteen Days”. We shall then attempt to characterize what is special about the ontological realism of “Sixteen Days” as contrasted to the linguistic constructivism which represents the more dominant current in contemporary analytic philosophy. This (...) will allow us to infer guidelines for assessing the quality of ontological theories of various types. We shall argue that ontological parsimony, groundedness, faithfulness to ordinary language, consistency with science, coherence, and fruitfulness are at least part of the adequacy criteria for such theories. These criteria will then be applied to the theory presented in “Sixteen Days”, and they will lead us to some revisions of this theory as well as to some reflections on its ethical implications.

Does a political conception of human rights dictate a particular view of corporate human rights obligations? The U.N. “Protect, Respect, and Remedy” Framework and Guiding Principles on Business and Human Rights hold that corporations have only a responsibility to respect human rights. Some critics have argued that corporations should be responsible for a wider range of human rights obligations, beyond merely an obligation to respect such rights. Furthermore, it has been argued that the Framework relied on a political conception of (...) human rights, and this is what led to limiting corporate obligations to mere respect for human rights. In this paper, I explore and critically assess this general claim about political conceptions of human rights. This involves distinguishing different types of political conceptions of human rights, as well as specifying what makes a theory of human rights a “political conception.” In light of this clarificatory discussion, I argue that the general thesis is false; the mere fact that a theory offers a political conception of human rights does not necessarily entail any certain range of corporate human rights obligations. Finally, I identify some of the other aspects of a theory of human rights that do affect the range of corporate obligations it will prescribe. (shrink)

A descriptive polytheist thinks there are at least two gods. John Hick and Richard Swinburne are descriptive polytheists. In this respect, they are like Thomas Aquinas and many other theists. What sets Swinburne and Hick apart from Aquinas, however, is that unlike him they are normative polytheists. That is, Swinburne and Hick think that it is right that we, or at least some of us, worship more than one god. However, the evidence available to me shows that only Swinburne, and (...) not Hick, is a cultic polytheist: he actually worships more than one god. I conclude that only Swinburne is a polytheist par excellence. (shrink)

The notion of “hierarchy” is one of the most commonly posited organizational principles in systems neuroscience. To this date, however, it has received little philosophical analysis. This is unfortunate, because the general concept of hierarchy ranges over two approaches with distinct empirical commitments, and whose conceptual relations remain unclear. We call the first approach the “representational hierarchy” view, which posits that an anatomical hierarchy of feed-forward, feed-back, and lateral connections underlies a signal processing hierarchy of input-output relations. Because the representational (...) hierarchy view holds that unimodal sensory representations are subsequently elaborated into more categorical and rule-based ones, it is committed to an increasing degree of abstraction along the hierarchy. The second view, which we call “topological hierarchy", is not committed to different representational functions or degrees of abstraction at different levels. Topological approaches instead posit that the hierarchical level of a part of the brain depends on how central it is to the pattern of connections in the system. Based on the current evidence, we argue that three conceptual relations between the two approaches are possible: topological hierarchies could substantiate the traditional representational hierarchy, conflict with it, or contribute to a plurality of approaches needed to understand the organization of the brain. By articulating each of these possibilities, our analysis attempts to open a conceptual space in which further neuroscientific and philosophical reasoning about neural hierarchy can proceed.

This paper builds on the system of David Lewis’s “Parts of Classes” to provide a foundation for mathematics that arguably requires not only no distinctively mathematical ideological commitments (in the sense of Quine), but also no distinctively mathematical ontological commitments. Provided only that there are enough individual atoms, the devices of plural quantification and mereology can be employed to simulate quantification over classes, while at the same time allowing all of the atoms (and most of their fusions with which we (...) are concerned) to be individuals (that is, urelements of classes). The final section of the paper canvasses some reasons to be committed to the required ontology for other than mathematical reasons. (shrink)

Cases of non-traditional family-making offer a rich seam for thinking about normative parenthood. Gamete donors are genetically related to the resulting offspring but are not thought to be normative parents. Gestational surrogates are also typically not thought to be normative parents, despite having gestated a child. Adoptive parents are typically thought to be normative parents even though they are neither genetically nor gestationally related to their child. Philosophers have paid attention to these kinds of cases. But they have not paid (...) attention to what the people who have engaged in these forms of family-making have to say about what they’re doing and, more specifically, how they answer the questions: “Who is the normative parent? And why?” Paying attention to their answers reveals two things. First, accounts of parenthood from people involved in two forms of non-traditional family-making – reproduction with gestational surrogacy and reproduction with donated eggs – are mutually inconsistent. This is not surprising. What is surprising is that the contradictory aspects of the views evince a common commitment to, as I shall put it, naturalizing parenthood. The central goal of this paper is to explain what that means, but rough idea is that in naturalizing parenthood, prospective parents aim to put the features that make someone a normative parent beyond the reach of human agency. I conclude by briefly suggesting that we should think of the grounds of normative parenthood – and the very task of theorizing about the grounds of normative parenthood – in a way that avoids the need to naturalize altogether.
