Gideon Rosen, Brian Leiter, and Catarina Dutilh Novaes raise deep questions about the arguments in Morality and Mathematics (M&M). Their objections bear on practical deliberation, the formulation of mathematical pluralism, the problem of universals, the argument from moral disagreement, moral ‘perception’, the contingency of our mathematical practices, and the purpose of proof. In this response, I address their objections, and the broader issues that they raise.

Paul Benacerraf's argument from multiple reductions consists of a general argument against realism about the natural numbers (the view that numbers are objects), and a limited argument against reductionism about them (the view that numbers are identical with prima facie distinct entities). There is a widely recognized and severe difficulty with the former argument, but no comparably recognized such difficulty with the latter. Even so, reductionism in mathematics continues to thrive. In this paper I develop a difficulty for Benacerraf's argument (...) against reductionism that is of comparable severity to the now widely recognized difficulty with his general argument against realism.

There is a long tradition comparing moral knowledge to mathematical knowledge. In this paper, I discuss apparent similarities and differences between knowledge in the two areas, realistically conceived. I argue that many of these are only apparent, while others are less philosophically significant than might be thought. The picture that emerges is surprising. There are definitely differences between epistemological arguments in the two areas. However, these differences, if anything, increase the plausibility of moral realism as compared to mathematical realism. It (...) is hard to see how one might argue, on epistemological grounds, for moral antirealism while maintaining commitment to mathematical realism. But it may be possible to do the opposite.

Holly Smith has done more than anyone to explore and defend the importance of usability for moral theories. In Making Morality Work, she develops a moral theory that is almost universally usable. But not quite. In this article, I argue that no moral theory is universally usable, in the sense that is most immediately relevant to action, even by agents who know all the normative facts. There is no moral theory knowledge of which suffices to settle deliberation about what to (...) do. However, this is unsurprising if the question of what to do is not a question of fact. One upshot of the discussion is that the search for a universally usable moral theory is misconceived. Another is that, contra Smith (341), agents who are radically uncertain need not lack autonomy.

Utilitarianism has dominated media ethics for a century. For Mill, individual autonomy and neutrality are the foundations of his On Liberty and System of Logic, as well as his Utilitarianism. These concepts fit naturally with media ethics theory and professional practice in a democratic society. However, the weaknesses in utilitarianism articulated by Ross and others direct us at this stage to a dialogic ethics of duty instead. Habermas's discourse ethics, feminist ethics, and communitarian ethics are examples of duty ethics rooted (...) in the dialogic relation that enable us to start over intellectually. (shrink)

The dominant route to nondescriptivist views of normative and evaluative language is through the expressivist idea that normative terms have distinctive expressive roles in conveying our attitudes. This paper explores an alternative route based on two ideas. First, a core normative term ‘ought’ is a modal operator; and second, modal operators play a distinctive nonrepresentational role in generating meanings for the statements in which they figure. I argue that this provides for an attractive alternative to expressivist forms of nondescriptivism about (...) normative language. In the final section of the paper, I explore ways it might be extended to evaluative language. (shrink)

This paper draws on the 'Fitting Attitudes' analysis of value to argue that we should take the concept of fittingness (rather than value) as our normative primitive. I will argue that the fittingness framework enhances the clarity and expressive power of our normative theorising. Along the way, we will see how the fittingness framework illuminates our understanding of various moral theories, and why it casts doubt on the Global Consequentialist idea that acts and (say) eye colours are normatively on a (...) par. We will see why even consequentialists, in taking rightness to be in some sense determined by goodness, should not think that rightness is conceptually reducible to goodness. Finally, I will use the fittingness framework to explicate the distinction between consequentialist and deontological theories, with particular attention to the contentious case of Rule Consequentialism.

Scholars have often considered evolutionary social theories a product of Positivist scientism and the naturalization of ethics. Yet the theistic foundations of many evolutionary theories proposed between the nineteenth and the twentieth centuries bolstered the belief that following natural laws was morally desirable, if not vital, to guaranteeing social and moral progress. In the early twentieth century, American paleontologist and leading evolutionist Henry Fairfield Osborn represented one of the most authoritative advocates of this interpretation of natural normativity. Particularly during the (...) last years of his career, Osborn used theological arguments to reinforce his advocacy of evolutionary ethics and social control policies, which led him to challenge his “old master” Thomas Huxley regarding the separation between evolution and moral conduct. This article examines the development of Osborn’s evolutionary ethics, with particular regard to its bearing on the American debate on euthenics. I argue that theistic topics played a major rhetorical role in the attempt to justify normative conclusions drawn from ostensible laws of evolution. (shrink)

Given the pervasiveness of AI systems and their potential negative effects on people’s lives (especially among already marginalised groups), it becomes imperative to comprehend what goes on when an AI system generates a result, and based on what reasons, it is achieved. There are consistent technical efforts for making systems more “explainable” by reducing their opaqueness and increasing their interpretability and explainability. In this paper, we explore an alternative non-technical approach towards explainability that complement existing ones. Leaving aside technical, statistical, (...) or data-related issues, we focus on the very conceptual underpinnings of the design decisions made by developers and other stakeholders during the lifecycle of a machine learning project. For instance, the design and development of an app to track snoring to detect possible health risks presuppose some picture or another of “health”, which is a key notion that conceptually underpins the project. We take it as a premise that these key concepts are necessarily present during design and development, albeit perhaps tacitly. We argue that by providing “justificatory explanations” about how the team understands the relevant key concepts behind its design decisions, interested parties could gain valuable insights and make better sense of the workings and outcomes of systems. Using the concept of “health”, we illustrate how a particular understanding of it might influence decisions during the design and development stages of a machine learning project, and how making this explicit by incorporating it into ex-post explanations might increase the explanatory and justificatory power of these explanations. We posit that a greater conceptual awareness of the key concepts that underpin design and development decisions may be beneficial to any attempt to develop explainability methods. We recommend that “justificatory explanations” are provided as technical documentation. These are declarative statements that contain at its simplest: (1) a high-level account of the understanding of the relevant key concepts a team possess related to a project’s main domain, (2) how these understandings drive decision-making during the life-cycle stages, and (3) it gives reasons (which could be implicit in the account) that the person or persons doing the explanation consider to have plausible justificatory power for the decisions that were made during the project.

While the modern revival of virtue ethics largely looks back to Aristotle, most, if not all, versions of this trend continue to be much indebted to and/or based upon specific mid‐twentieth‐century neo‐naturalist and descriptivist critiques of prevailing antinaturalist trends of that time: specifically, upon Anscombe's critique of the ethics of duty and utility and of the so‐called modern moral ought, and Geach's robust defence of the descriptive character of moral and other goodness. However, in the wake of further critical attention (...) to these neo‐naturalist claims, this paper argues that there can ultimately be no reliable or secure logical or empirical grounding of the virtues of inherently normative human moral life and conduct in the goods or virtues of effective or even beneficial natural function.

A vexing problem in contemporary epistemology—one with origins in Plato’s Meno—concerns the value of knowledge, and in particular, whether and how the value of knowledge exceeds the value of mere true opinion. The recent literature is deeply divided on the matter of how best to address the problem. One point, however, remains unquestioned: that if a solution is to be found, it will be at the personal level, the level at which states of subjects or agents, as such, appear. We (...) take exception to this orthodoxy, or at least to its unquestioned status. We argue that subpersonal states play a significant—arguably, primary—role in much epistemically relevant cognition and thus constitute a domain in which we might reasonably expect to locate the “missing source” of epistemic value, beyond the value attached to mere true belief.

This paper attempts to locate, within an actualist ontology, truthmakers for modal truths: truths of the form or . In Sect. 1 I motivate the demand for substantial truthmakers for modal truths. In Sect. 21 criticise Armstrong's account of truthmakers for modal truths. In Sect. 31 examine essentialism and defend an account of what makes essentialist attributions true, but I argue that this does not solve the problem of modal truth in general. In Sect. 41 discuss, and dismiss, a theistic (...) account of the source of modal truth proposed by Alexander Pruss. In Sect. 5 I offer a means of (dis)solving the problem. (shrink)

G.E. Moore said that rightness was obviously a matter of maximising plain goodness. Peter Geach and Judith Thomson disagree. They have both argued that ‘good’ is not a predicative adjective, but only ever an attributive adjective: just like ‘big.’ And just as there is no such thing as plain bigness but only ever big for or as a so-and-so, there is also no such thing as plain goodness. They conclude that Moore’s goodness is thus a nonsense. However attention has been (...) drawn to a weakness in their arguments. Mahrad Almotahari and Adam Hosein have sought to plug that weakness. If their plug holds, then there is no goodness. Doing most of their work is the following premise: adjective φ is predicative only if it can be used predicatively in ‘x is a φ K’ otherwise it is attributive. In this paper I argue that this premise is false, that their plug does not hold and that if one is to reject plain goodness it will have to be for other reasons. (shrink)

Recently, there has been a revival in taking empirical magnitudes seriously. Weights, heights, velocities and the like have been accepted as abstract entities in their own right rather than just equivalence classes of objects. The aim of my paper is to show that this revival should include value magnitudes. If we posit such magnitudes, important value comparisons can be easily explained; it becomes easier to satisfy the axioms for measurement of value; goodness, badness, and neutrality can be given univocal definitions; (...) value aggregation can be given a non-mathematical understanding which allows for Moorean organic unities. Of course, this does not come for free. One has to accept a rich ontology of abstract value magnitudes, but, to quote David Lewis, ‘The price is right; the benefits in theoretical unity and economy are well worth the entities.’. (shrink)

This paper pursues a value-based evaluation of a variety of character traits which philosophers have identified with humility, and it proposes a novel account of a character trait not implausibly identified with humility which has a unique kind of value. I begin by explaining why a value-based evaluation of various traits identified with virtues is preferable to the more common contemporary counterexample-based evaluation of these traits. I then undertake a value-based evaluation of various traits which have been identified with humility, (...) showing that thus far none of these traits have a particular kind of value that humility might reasonably be thought to have—a nonameliorative value not based in epistemic, affective, or behavioral accuracy. I conclude by developing an account of a character trait not implausibly identified with humility which does have this kind of value. The trait in question is a disposition to prefer promoting the good of others to one’s own good when these goods are equal or incommensurable. (shrink)

Can a normative reason be understood as a kind of explanation? I here consider and argue against two important analyses of reasons as explanations. John Broome argues that we can analyze reasons in terms of the concepts of explanation and ought. On his view, reasons to ϕ are either facts that explain why one ought to ϕ (what he calls “perfect reasons”) or facts that play a for-ϕ role in weighing explanations (what he calls “pro tanto reasons”). I argue against (...) Broome’s account of both perfect and pro tanto reasons. Other philosophers, including Joseph Raz, analyze reasons in terms of the concepts of explanation and good. On this view, some fact is a reason to ϕ if and only if that fact explains why ϕ-ing would be good in some respect, to some degree. This view avoids the objections to Broome’s view, but should be rejected since not all explanations of why ϕ-ing would be good constitute reasons to ϕ. (shrink)

Whether value is “additive,” that is, whether the value of a whole must equal the sum of the values of its parts, is widely thought to have significant implications in ethics. For example, additivity rules out “organic unities,” and is presupposed by “contrast arguments.” This paper reconsiders the significance of value additivity. The main thesis defended is that it is significant only for a certain class of “mereologies”, roughly, those in which both wholes and parts are “complete”, in the sense (...) that they can exist independently. For example, value additivity is significant in the case of a mereology of material objects, but not in the case of a mereology of propositions. (shrink)

Frege appears to hold both that thoughts are internally articulated, in a way that mirrors the semantic articulation of the sentences that express them, and that the same thought can be analyzed in different ways, none of which has to be more fundamental than the others. Commentators have often taken these theses to be mutually incompatible and have tended to polarize into two camps, each of which attributes to Frege one of the theses, but maintains that he is only apparently (...) committed to the other. This paper argues that there are good exegetical and philosophical reasons for reconciling the two theses; that this reconciliation can be achieved by rejecting an assumption shared by the two opposite camps of the exegetical debate, i.e., the assumption that essential articulatedness implies unique articulation; and finally, that this crucial assumption can be resisted by appreciating Frege’s anti-atomistic and ‘organic’ conception of the internal complexity of thoughts.

Since G. E. Moore introduced his concept of organic unity there has been some discussion of how one should best understand this notion and whether there actually are any organic unities in the Moorean sense. Such discussions do however often put general questions about part-whole relations to the side and tend to focus on interpreting our intuitive responses to possible cases of organic unity. In this paper the focus lies on the part-whole relation in valuable wholes and it is suggested (...) that we should distinguish between two kinds of wholes, collections and complex unities, where the latter can involve values that do not pass on their value to the greater whole in which they are included. Given this distinction we are then able to distinguish between two kinds of organic unity phenomena, the first involving a form of goodness that emerges on the level of the whole, the second involving a form of goodness that is embedded on the level of parts. In order to properly understand the latter form of goodness, there is also a need to distinguish final value from inherent value. (shrink)

The central question addressed in this paper is about the ethics of engaging with educational development in countries perceived as undemocratic or as failing to respect human rights. More particularly, it examines the nature of the arguments that are brought to bear on this issue. It suggests that these are essentially consequentialist in character and hence fall prey to many of the limitations of such consequentialism, including the unpredictability of what will unfold, the indeterminacy of the consequences and the complex (...) balance sheet of benefits and loss that might be anticipated. The paper also suggests some unease about the way judgements of the acceptability or otherwise of political processes are made across international boundaries and the presumptions of a ‘democratic’ western perspective. The observation of these complexities of principle and fact take the argument into the territory of case-based ethical judgement and the world of casuistry. (shrink)

Essentialism is widely regarded as a mistaken view of biological kinds, such as species. After recounting why (sections 2-3), we provide a brief survey of the chief responses to the “death of essentialism” in the philosophy of biology (section 4). We then develop one of these responses, the claim that biological kinds are homeostatic property clusters (sections 5-6) illustrating this view with several novel examples (section 7). Although this view was first expressed 20 years ago, and has received recent discussion (...) and critique, it remains underdeveloped and is often misrepresented by its critics (section 8). (shrink)

The prospects for moral realism and ethical naturalism have been important parts of recent debates within metaethics. As a first approximation, moral realism is the claim that there are facts or truths about moral matters that are objective in the sense that they obtain independently of the moral beliefs or attitudes of appraisers. Ethical naturalism is the claim that moral properties of people, actions, and institutions are natural, rather than occult or supernatural, features of the world. Though these metaethical debates (...) remain unsettled, several people, myself included, have tried to defend the plausibility of both moral realism and ethical naturalism. I, among others, have appealed to recent work in the philosophy of language—in particular, to so-called theories of “direct reference” —to defend ethical naturalism against a variety of semantic worries, including G. E. Moore's “open question argument.” In response to these arguments, critics have expressed doubts about the compatibility of moral realism and direct reference. In this essay, I explain these doubts, and then sketch the beginnings of an answer—but understanding both the doubts and my answer requires some intellectual background. (shrink)

Diachronic Dutch book arguments seem to support both conditionalization and Bas van Fraassen's Reflection principle. But the Reflection principle is vulnerable to numerous counterexamples. This essay addresses two questions: first, under what circumstances should an agent obey Reflection, and second, should the counterexamples to Reflection make us doubt the Dutch book for conditionalization? In response to the first question, this essay formulates a new "Qualified Reflection" principle, which states that an agent should obey Reflection only if he or she is (...) certain that he or she will conditionalize on veridical evidence in the future. Qualified Reflection follows from the probability calculus together with a few idealizing assumptions. The essay then formulates a "Distorted Reflection" principle that approximates Reflection even in cases where the agent is not quite certain that he or she will conditionalize on veridical evidence. In response to the second question, the essay argues that contrary to a common misconception, not all Dutch books dramatize incoherence—some dramatize a less blameworthy sort of epistemic frailty that the essay calls "self-doubt." The distinction between Dutch books that dramatize incoherence and those that dramatize self-doubt cross-cuts the distinction between synchronic and diachronic Dutch books. The essay explains why the Dutch book for conditionalization reveals true incoherence, whereas the Dutch book for Reflection reveals only self-doubt. (shrink)

In this article, I attempt to resuscitate the perennially unfashionable distinctive feeling theory of pleasure (and pain), according to which for an experience to be pleasant (or unpleasant) is just for it to involve or contain a distinctive kind of feeling. I do this in two ways. First, by offering powerful new arguments against its two chief rivals: attitude theories, on the one hand, and the phenomenological theories of Roger Crisp, Shelly Kagan, and Aaron Smuts, on the other. Second, by (...) showing how it can answer two important objections that have been made to it. First, the famous worry that there is no felt similarity to all pleasant (or unpleasant) experiences (sometimes called ‘the heterogeneity objection’). Second, what I call ‘Findlay’s objection’, the claim that it cannot explain the nature of our attraction to pleasure and aversion to pain. (shrink)

Recent literature on intrinsic value contains a number of disputes about the nature of the concept. On the one hand, there are those who think states of affairs, such as states of pleasure or desire satisfaction, are the bearers of intrinsic value (“Mooreans”); on the other hand, there are those who think concrete objects, like people, are intrinsically valuable (“Kantians”). The contention of this paper is that there is not a single concept of intrinsic value about which Mooreans and Kantians (...) have disagreed, but rather two distinct concepts. I state a number of principles about intrinsic value that have typically (though not universally) been held by Mooreans, all of which are typically denied by Kantians. I show that there are distinct theoretical roles for a concept of intrinsic value to play in a moral framework. When we notice these distinct theoretical roles, we should realize that there is room for two distinct concepts of intrinsic value within a single moral framework: one that accords with some or all of the Moorean principles, and one that does not.

Should philosophers prefer simpler theories? Huemer (Philos Q 59:216–236, 2009) argues that the reasons to prefer simpler theories in science do not apply in philosophy. I will argue that Huemer is mistaken—the arguments he marshals for preferring simpler theories in science can also be applied in philosophy. Like Huemer, I will focus on the philosophy of mind and the nominalism/Platonism debate. But I want to engage with the broader issue of whether simplicity is relevant to philosophy.

What does logic tells us how about we ought to reason? If P entails Q, and I believe P, should I believe Q? I will argue that we should embed the issue in an independently motivated contextualist semantics for ‘ought’, with parameters for a standard and set of propositions. With the contextualist machinery in hand, we can defend a strong principle expressing how agents ought to reason while accommodating conflicting intuitions. I then show how our judgments about blame and guidance (...) can be handled by this machinery. (shrink)

Accoding to G.E. Moore, something''s intrinsic valuedepends solely on its intrinsic nature. Recently Thomas Hurka andShelly Kagan have argued, contra Moore, that something''s intrinsic valuemay depend on its extrinsic properties. Call this view the ConditionalView of intrinsic value. In this paper I demonstrate how a Mooreancan account for purported counterexamples given by Hurka and Kagan. I thenargue that certain organic unities pose difficulties for the ConditionalView.

This paper examines the view of ethical language that Wittgenstein took in later years. It argues that according to this view, ethics falls into place as a part of our natural history, while every sense of the mystical or supernatural that once surrounded it is irrevocably lost. Moreover, Wittgenstein argues that ethical language does not correspond to reality “in the way” in which a physical theory does. I propose an interpretation of this claim that shows how it sets his view (...) apart from a “realist” theory of ethics. The reality of which he speaks is the reality of human life. (shrink)

that there is something rationally or conceptually defective in judging that an act is right without being in any way motivated towards it—is one which has tended to lead either to error theories of ethics on the one hand, or acceptance of the truth of internalism on the other. This paper argues that it does play a kind of subject-setting role, but that our responses to cases can be rationalised without requiring that internalism is true for ethical realism to be (...) vindicated. Instead what is required is that something like internalism be believed to be true. The widespreadness of the internalist intuition is part of what makes it the case that some actions are right and others wrong. Of course these beliefs might be false—as the present author holds—consistent with ethical realism, just so long as they are widely held, and whatever else it takes to vindicate realism is the case. In such a situation, widespread false belief would be part of what makes it so that some acts are right, and others wrong. (shrink)

Sometimes people desire that their lives go badly, take pleasure in their lives going badly, or believe that their lives are going badly. As a result, some popular theories of welfare are paradoxical. I show that no attempt to defend those theories from the paradox fully succeeds.

Pedigree dog breeding has been the subject of public debate due to health problems caused by breeding for extreme looks and the narrow genepool of many breeds. Our research aims to provide insights in order to further the animal-ethical, political and society-wide discussion regarding the future of pedigree dog breeding in the Netherlands. Guided by the question ‘How far are we allowed to interfere in the genetic make-up of dogs, through breeding and genetic modification?’, we carried out a multi-method case-driven (...) research, reviewing literature as well as identifying the perceptions of pedigree dog breeding of a variety of parties in the Netherlands. We examined what moral arguments and concepts different stakeholders, including breeders, veterinarians and animal protection societies, put forward when considering this question. While welfare arguments were often used as a final justification, we also frequently encountered arguments beyond welfare in practice, in particular the arguments that certain adaptations were unnatural, that they instrumentalised animals, or that they amounted to playing God. We argue that the way these arguments are employed points to a virtue ethical approach, foregrounding the virtue of temperance, as a balance between extreme positions was sought by our respondents in a variety of ways. Moreover, we argue against a rejection of unnaturalness arguments based on the naturalistic fallacy, as philosophers tend to do. We point out that unnaturalness arguments are related to people’s worldviews, including views on the proper human–animal relationship. We argue that such arguments, which we label ‘life-ethical’, should be the subject of more public discussion and should not be relegated to the private sphere. (shrink)

In Why Tolerate Religion?, Brian Leiter argues against the special legal status of religion, claiming that religion should not be the only ground for exemptions to the law and that this form of protection should be, in principle, available for the claims of secular conscience as well. However, in the last chapter of his book, he objects to a universal regime of exemptions for both religious and secular claims of conscience, highlighting the practical and moral flaws associated with it. We (...) believe that Leiter identifies a genuine and important contemporary legal and philosophical problem. We find much to admire in his reasoning. However, we raise questions about two claims that are crucial for his argument. The first claim is that it is not religion as such, but conscience that deserves toleration and respect. The second claim is that respect for religion and conscience demands ‘principled toleration’ but does not entail stronger policies of legal exemptions. Against the first claim, we argue that Leiter does not successfully distinguish religious belief from secular conscience and morality; and he does not explain why secular conscience deserves respect. Against the second claim, we argue that the most promising theories of legal exemptions are not classical theories of liberal toleration. (shrink)

The central recommendation of this article is that philosophers trained in the analytic tradition ought to add the sensibilities and skills of the historian to their methodological toolkit. The value of an historical approach to strictly philosophical matters is illustrated by a case study focussing on the medieval origin of conceivability arguments and contemporary views of modality. It is shown that common metaphilosophical views about the nature of the philosophical enterprise as well as certain inference patterns found in thinkers from (...) Descartes to Chalmers have their origin in the theological concerns of the Scholastics. Since these assumptions and inference patterns are difficult to motivate when shorn of their original theological context, the upshot is that much post-Cartesian philosophy is cast in an altogether unfamiliar, and probably unwelcome, light. The methodological point, however, is that this philosophical gain is born of acquaintance with the history of ideas. (shrink)

Prominent ethical and policy issues such as affirmative action and female enrollment in science and engineering revolve around the idea that diversity is good. However, a precise definition is seldom provided. I show that diversity may be construed as a factual description, a craving for symmetry, an intrinsic good, an instrumental good, a symptom, or a side effect. These acceptions differ vastly in their nature and properties. Some are deeply mistaken and some others cannot lead to concrete policies. It is (...) thus necessary to clarify what one means by ‘diversity.’ It may be a neutral description of a given state; but this is insufficient to act. The idea that there should be the same representation in a specific context as in the overall population is both puzzling and arbitrary. Diversity as intrinsic good is a mere opinion, which cannot be concretely applied; moreover, the most commonly invoked forms of diversity are not intrinsically good. On the other hand, diversity as instrumental good can be evaluated empirically and can give rise to policies, but these may be very weak. Finally, symptoms and side effects are not actually about diversity. I consider the example of female enrollment in science and engineering, interpreting the various arguments found in the literature in light of this polysemy. (shrink)

The Darwinian theory of evolution is itself evolving and this book presents the details of the core of modern Darwinism and its latest developmental directions. The authors present current scientific work addressing theoretical problems and challenges in four sections, beginning with the concepts of evolution theory, its processes of variation, heredity, selection, adaptation and function, and its patterns of character, species, descent and life. The second part of this book scrutinizes Darwinism in the philosophy of science and its usefulness in (...) understanding ecosystems, whilst the third section deals with its application in disciplines beyond the biological sciences, including evolutionary psychology and evolutionary economics, Darwinian morality and phylolinguistics. The final section addresses anti-Darwinism, the creationist view and issues around teaching evolution in secondary schools. The reader learns how current experimental biology is opening important perspectives on the sources of variation, and thus of the very power of natural selection. This work examines numerous examples of the extension of the principle of natural selection and provides the opportunity to critically reflect on a rich theory, on the methodological rigour that presides in its extensions and exportations, and on the necessity to measure its advantages and also its limits. Scholars interested in modern Darwinism and scientific research, its concepts, research programs and controversies will find this book an excellent read, and those considering how Darwinism might evolve, how it can apply to the human sciences and other disciplines beyond its origins will find it particularly valuable. Originally produced in French (Les Mondes Darwiniens), the scope and usefulness of the book have led to the production of this English text, to reach a wider audience. This book is a milestone in the impressive penetration by Francophone scholars into the world of Darwinian science, its historiography and philosophy over the last two decades. Alex Rosenberg, R.

A continuous objection to virtue ethics has been its alleged inadequacy in providing a distinctive account of right action and determinate action guidance. The virtue ethical criterion “An action is right if and only if it is what a virtuous agent would characteristically (i.e., acting in character) do in the circumstances,” has been claimed by some to give wrong results in some cases, and thus doomed to failure. However, I argue that the opponents who raise these objections overlook an important (...) distinction between “action assessment” and “action guidance” in virtue ethics. Once this distinction which is alien to other dominant moral theories is taken into consideration, I show that virtue ethics can supply a distinctive theory of right action and sufficient action guidance. Moreover, I will demonstrate that this distinction allows us to see that virtue ethics has some structural advantages that enable it to provide multiple guidance strategies to different agents with differential cognitive and moral developmental levels. Finally, I will argue that while theories that tell moral agents what to do by providing exact answers might affect moral agency in negative ways by frustrating the development of an integrated moral character, virtue ethics also avoids this effect.

In this article, we critically reflect on the concept of biomimicry. On the basis of an analysis of the concept of biomimicry in the literature and its philosophical origin, we distinguish between a strong and a weaker concept of biomimicry. The strength of the strong concept of biomimicry is that nature is seen as a measure by which to judge the ethical rightness of our technological innovations, but its weakness is found in questionable presuppositions. These presuppositions are addressed by the (...) weaker concept of biomimicry, but at the price that it is no longer possible to distinguish between exploitative and ecological types of technological innovations. We compare both concepts of biomimicry by critically reflecting on four dimensions of the concept of biomimicry: mimesis, technology, nature, and ethics. (shrink)

Many philosophers think that moral objectivism is supported by stable features of moral discourse and thinking. When engaged in moral reasoning and discourse, people behave ‘as if’ objectivism were correct, and the seemingly most straightforward way of making sense of this is to assume that objectivism is correct; this is how we think that such behavior is explained in paradigmatically objectivist domains. By comparison, relativist, error-theoretic or non-cognitivist accounts of this behavior seem contrived and ad hoc. After explaining why this (...) argument should be taken seriously (recent arguments notwithstanding), I argue that it is nevertheless undermined by considerations of moral disagreement. Even if the metaphysical, epistemic and semantic commitments of objectivism provide little or no evidence against it, and even if the alternative explanations of ‘objectivist’ traits of moral discourse and thinking are speculative or contrived, objectivism is itself incapable of making straightforward sense of these traits. Deep and widespread moral disagreement or, rather, the mere appearance of such disagreement, strongly suggests that the explanations operative in paradigmatically objective discourse fail to carry over to the moral case. Since objectivism, no less than relativism, non-cognitivism and error-theories, needs non-trivial explanations of why we behave ‘as if’ objectivism were correct, such behavior does not presently provide reason to accept objectivism.

In the first place, I propose to specify the debate between non-anthropocentrists and anthropocentrists as one between those who defend that the environment has intrinsic value, that is, value that while independent of all relation to human beings is still morally binding, and those who deny this, i.e., assert that the environment only has extrinsic value. I argue for the second option but claim that this should not be an obstacle to address some of the worries of environmental ethics, since (...) extrinsic value is not limited to instrumental value. In this regard, I present sentimentalism as an alternative according to which there are ways of valuing things as ends in themselves and not only as means. (shrink)

I argue—contra moderate grounding pluralists such as Kit Fine and more extreme grounding pluralists such as Jessica Wilson—that there is fundamentally only one grounding/in-virtue-of relation. I also argue that this single relation is indispensable for normative theorizing—that we can’t make sense of, for example, the debate over consequentialism without it. It follows from what I argue that there is no metaethically-pure normative ethics.

This paper investigates the differences between ancient Greek and modern ethical naturalism, through the account of the whole classical tradition provided by Cicero in De finibus bonorum et malorum. Ever since Hume’s remarks on the topic, it is usually held that derivations of normative claims from factual claims require some kind of proper justification. It ́s a the presence of such justifications in the Epicurean, Stoic, and Academic-Peripatetic ethical theories (as portrayed in De finibus), and, after a negative conclusion, I (...) argue that we should conceive of this issue within a social-historical perspective: The radical difference between ancient and modern naturalistic ethics is due (in Weber’s terms) to the rationalization processes that generated the modern outlook on nature.

I distinguish four current strategies for integrating a rhetorical perspective within normative models for argumentation. Then I propose and argue for a fifth one by defending a conception of acts of arguing as having a rhetorical dimension that provides conditions for characterizing good argumentation, understood as argumentation that justifies a target-claim.

The paper aims to provide a detailed assessment of Tim Crane’s recent invocation of the notion of scientific models in the way of dealing with the issue of the brain’s representational states. In this paper, I assess Crane’s proposal under a charitable and a less charitable reading. I argue that Crane’s use of scientific models is at best compatible with his expression of psychological realism. However, Crane’s use of model-based strategy by no means underlay, support, or strengthen his psychological realism. (...) Rather, traditional reasons from the metaphysics of mind, acting quite separately from empirical scientific reasons, must be used to support this realism, and Crane has merely removed the threat posed to these metaphysical arguments by the existence of the so-called mereological fallacy in empirical neuroscience. Therefore, while he has saved the neuroscientific language from philosophical attack, he has perhaps even strengthened the divide between neuroscience and philosophy. I conclude the paper by outlining the sketch of a broadbrush scientifically informed strategy for defending psychological realism. (shrink)
