Science communication via testimony requires a certain level of trust. But in the context of ideologically-entangled scientific issues, trust is in short supply—particularly when the issues are politically ‘entangled’. In such cases, cultural values are better predictors than scientific literacy for whether agents trust the publicly-directed claims of the scientific community. In this paper, we argue that a common way of thinking about scientific literacy—as knowledge of particular scientific facts or concepts—ought to give way to a second-order understanding of science (...) as a process as a more important notion for the public’s trust of science.

In this major new work, Matthew Kramer seeks to establish two main conclusions. On the one hand, moral requirements are strongly objective. On the other hand, the objectivity of ethics is itself an ethical matter that rests primarily on ethical considerations. Moral realism - the doctrine that morality is indeed objective - is a moral doctrine. Major new volume in our new series _New Directions in Ethics_ Takes on the big picture - defending the objectivity of ethics whilst rejecting (...) the grounds of much of the existing debate between realists and anti-realists Cuts across both ethical theory and metaethics Distinguished by the quality of the scholarship and its ambitious range.

Philosophers have long been interested in a series of interrelated questions about natural kinds. What are they? What role do they play in science and metaphysics? How do they contribute to our epistemic projects? What categories count as natural kinds? And so on. Owing, perhaps, to different starting points and emphases, we now have at hand a variety of conceptions of natural kinds—some apparently better suited than others to accommodate a particular sort of inquiry. Even if coherent, this situation isn’t (...) ideal. My goal in this article is to begin to articulate a more general account of ‘natural kind phenomena’. While I do not claim that this account should satisfy everyone—it is built around a certain conception of the epistemic role of kinds and has an obvious pragmatic flavour—I believe that it has the resources to go further than extant alternatives, in particular the homeostatic property cluster view of kinds.

During the past several decades, political philosophers have frequently clashed with one another over the question whether governments are morally required to remain neutral among reasonable conceptions of excellence and human flourishing. Whereas the numerous followers of John Rawls have maintained that a requirement of neutrality is indeed incumbent on every system of governance, other philosophers -- often designated as 'perfectionists' -- have argued against the existence of such a requirement. Liberalism with Excellence enters these debates not by plighting itself (...) unequivocally to one side or the other, but instead by reconceiving each of the sides and thus by redirecting the debates that have occurred between them. On the one hand, the book rejects the requirement of neutrality by contending that certain subsidies for the promotion of excellence in sundry areas of human endeavour can be proper and vital uses of resources by governments. Advocating such departures from the constraint of neutrality, the book presents a version of liberalism that can rightly be classified as 'perfectionist'. On the other hand, the species of perfectionism espoused in Liberalism with Excellence diverges markedly from the theories that have usually been so classified. Indeed, much of the book assails various aspects of those theories. What is more, the aspirational perfectionism elaborated in the closing chapters of the volume is reconcilable in most key respects with a suitably amplified version of Rawlsianism. Hence, by reconceiving both the perfectionist side and the neutralist side of the prevailing disputation, Liberalism with Excellence combines and transforms their respective insights. (shrink)

In this paper, I consider ways of responding to critiques of natural kinds monism recently suggested from the pluralist camp. Even if monism is determined to be untenable in certain domains (say, about species), it might well be tenable in others. Chemistry is suggested to be such a monist‐friendly domain. Suggestions of trouble for chemical kinds can be defused by attending to the difference between monism as a metaphysical thesis and as a claim about classification systems. Finally, I consider enantiomers (...) as a test case for the monism/pluralism debate. The question of whether enantiomers differ in kind does not appear easily answerable. I suggest that this legislates for pluralism in chemistry. (shrink)

Good chefs know the importance of maintaining sharp knives in the kitchen. What’s their secret? A well-worn Taoist allegory offers some advice. The king asks about his butcher’s impressive knifework. “Ordinary butchers,” he replied “hack their way through the animal. Thus their knife always needs sharpening. My father taught me the Taoist way. I merely lay the knife by the natural openings and let it find its own way through. Thus it never needs sharpening” (Kahn 1995, vii; see also Watson (...) 2003, 46). Plato famously employed this image as an analogy for the reality of his Forms (Phaedrus, 265e). Just like an animal, the world comes pre-divided for us. Ideally, our best theories will be those which “carve nature at its joints”. While Plato employed the “carving” metaphor to convey his views about the reality of his celebrated Forms, its most common contemporary use involves the success of science -- particularly, its success in identifying distinct kinds of things. Scientists often report discovering new kinds of things -- a new species of mammal or novel kind of fundamental particle, for example -- or uncovering more information about already familiar kinds. Moreover, we often notice considerable overlap in different approaches to classification. As Ernst Mayr put it: No naturalist would question the reality of the species he may find in his garden, whether it is a catbird, chickadee, robin, or starling. And the same is true for trees or flowering plants. Species at a given locality are almost invariably separated from each other by a distinct gap. Nothing convinced me so fully of the reality of species as the observation . . . that the Stone Age natives in the mountains of New Guinea recognize as species exactly the same entities of nature as a western scientist. (Mayr 1987, 146) Such agreement is certainly suggestive. It suggests that taxonomies are discoveries rather than mere inventions. Couple this with their utility in scientific inference and explanation and we have compelling reason for accepting the objective, independent reality of many different natural kinds of things..

This book is an uncompromising defense of legal positivism that insists on the separability of law and morality. After distinguishing among three facets of morality, Kramer explores a variety of ways in which law has been perceived as integrally connected to each of those facets. The book concludes with a detailed discussion of the obligation to obey the law--a discussion that highlights the strengths of legal positivism in the domain of political philosophy as much as in the domain of jurisprudence.

The authors of this book engage in essay form in a lively debate over the fundamental characteristics of legal and moral rights. They examine whether rights fundamentally protect individuals' interests or whether they instead fundamentally enable individuals to make choices. In the course of this debate the authors address many questions through which they clarify, though not finally resolve, a number of controversial present-day political debates, including those over abortion, euthanasia, and animal rights.

In his provocative book Matthew Kramer offers a systematic theory of freedom that challenges most of the other major contemporary treatments of the topic.

Taking a fresh look at a central controversy in criminal law theory, The Ethics of Capital Punishment presents a rationale for the death penalty grounded in a theory of the nature of evil and the nature of defilement. Original, unsettling, and deeply controversial, it will be an essential reference point for future debates on the subject.

How are law and morality connected, how do they interact, and in what ways are they distinct? In Part I of this book, Matthew Kramer argues that moral principles can enter into the law of any jurisdiction. He contends that legal officials can invoke moral principles as laws for resolving disputes, and that they can also invoke them as threshold tests which ordinary laws must satisfy. In opposition to many other theorists, Kramer argues that these functions of moral principles (...) are consistent with all the essential characteristics of any legal system. Part II reaffirms the legal positivist argument that law and morality are separable, arguing against the position of natural-law theory, which portrays legal requirements as a species of moral requirements. Kramer contends that even though the existence of a legal system in any sizeable society is essential for the realization of fundamental moral values, law is not inherently moral either in its effects or in its motivational underpinnings. In the final part, Kramer contests the widespread view that people whose conduct is meticulously careful cannot be held morally responsible for harmful effects of their actions. Through this argument, he reveals that fault-independent liability is present even more prominently in morality than in the law. Through a variety of arguments, Where Law and Morality Meet highlights both some surprising affinities and some striking divergences between morality and law. (shrink)

This chapter contains sections titled: Categorical Prescriptiveness Uniformity as a Moral Matter Uniformity Contrasted with Neutrality The Overridingness of Moral Principles.

What are species? Are they objective features of the world? If so, what sort of features are they? Do everyday intuitions that species are real stand up to philosophical and scientific scrutiny? Two rival accounts of species' reality have dominated the discussion: that species are natural kinds defined by essential properties and that species are individuals. Unfortunately, neither account fully accommodates biological practice. In Are Species Real?, Slater presents a novel approach to this question aimed at accommodating the attractions to (...) both realism and antirealism about species. (shrink)

The morality of interrogational torture has been the subject of heated debate in recent years. In explaining why torture is morally wrong, Kramer engages in deep philosophical reflections on the nature of morality and on moral conflicts.

Talk of different types of cells is commonplace in the biological sciences. We know a great deal, for example, about human muscle cells by studying the same type of cells in mice. Information about cell type is apparently largely projectible across species boundaries. But what defines cell type? Do cells come pre-packaged into different natural kinds? Philosophical attention to these questions has been extremely limited [see e.g., Wilson (Species: New Interdisciplinary Essays, pp 187–207, 1999; Genes and the Agents of Life, (...) 2005; Wilson et al. Philos Top 35(1/2):189–215, 2007)]. On the face of it, the problems we face in individuating cellular kinds resemble those biologists and philosophers of biology encountered in thinking about species: there are apparently many different (and interconnected) bases on which we might legitimately classify cells. We could, for example, focus on their developmental history (a sort of analogue to a species’ evolutionary history); or we might divide on the basis of certain structural features, functional role, location within larger systems, and so on. In this paper, I sketch an approach to cellular kinds inspired by Boyd’s Homeostatic Property Cluster Theory, applying some lessons from this application back to general questions about the nature of natural kinds.

Some important recent articles, including one in this journal, have sought to devise theories of rights that can transcend the longstanding debate between the Interest Theory and the Will Theory. The present essay argues that those efforts fail and that the Interest Theory and the Will Theory withstand the criticisms that have been levelled against them. To be sure, the criticisms have been valuable in that they have prompted the amplification and clarification of the two dominant theories of rights; but (...) their upshot has been to reveal the need for the improvement, rather than the abandonment, of those theories.

Matthew H. Bowker offers a novel analysis of "experience": the vast and influential concept that has shaped Western social theory and political practice for the past half-millennium. While it is difficult to find a branch of modern thought, science, industry, or art that has not relied in some way on the notion of "experience" in defining its assumptions or aims, no study has yet applied a politically-conscious and psychologically-sensitive critique to the construct of experience. Doing so reveals that most (...) of the qualities that have been attributed to experience over the centuries — particularly its unthinkability, its correspondence with suffering, and its occlusion of the self — are part of unlikely fantasies or ideologies. By analyzing a series of related cases, including the experiential education movement, the ascendency of trauma theory, the philosophy of the social contract, and the psychological study of social isolation, the book builds a convincing case that ideologies of experience are invoked not to keep us close to lived realities and ‘things-in-themselves,’ but, rather, to distort and destroy true knowledge of ourselves and others. In spite of enduring admiration for those who may be called champions of experience, such as Michel de Montaigne, Ralph Waldo Emerson, and others treated throughout the work, the ideologies of experience ultimately discourage individuals and groups from creating, resisting, and changing our experience, urging us instead to embrace trauma, failure, deprivation, and self-abandonment.

Different chemical species are often cited as paradigm examples of structurally delimited natural kinds. While classificatory monism may thus seem plausible for simple molecules, it looks less attractive for complex biological macromolecules. I focus on the case of proteins that are most plausibly individuated by their functions. Is there a single, objective count of proteins? I argue that the vagaries of function individuation infect protein classification. We should be pluralists about macromolecular classification.

Emotion and affect play a central role in persuasion, decision-making, and human behavior. Because of ongoing environmental crises, there is a strong need to better understand how emotions shape selection, attention, processing, and effects of environmental communication. Here, I highlight three main areas that contain challenges and opportunities for building a synergistic relationship between the affective sciences and research on strategic environmental communication: (a) identifying the causal effects of emotions in environmental communication; (b) the role of emotions in the durability (...) of environmental messaging effects; and (c) how closing the gap between the laboratory and the field can generate innovative research and more applicable inferences.

The scientific community, we hold, often provides society with knowledge—that the HIV virus causes AIDS, that anthropogenic climate change is underway, that the MMR vaccine is safe. Some deny that we have this knowledge, however, and work to undermine it in others. It has been common to refer to such agents as “denialists”. At first glance, then, denialism appears to be a form of skepticism. But while we know that various denialist strategies for suppressing belief are generally effective, little is (...) known about which strategies are most effective. We see this as an important first step toward their remediation. This paper leverages the approximate comparison to various forms of philosophical skepticism to design an experimental test of the efficacy of four broad strategies of denial at suppressing belief in specific scientific claims. Our results suggest that assertive strategies are more effective at suppressing belief than questioning strategies. (shrink)

Michael Ghiselin and David Hull’s individuality thesis is that biological species are individuals. Philosophers often treat the term “individual” as synonymous with “mereological sum” and characterize it in terms of mereology. It is easy to see how the biological project has been interpreted as a mereological one. This chapter argues that this is a mistake, that biological part/whole relations often violate the axioms of mereology. Conflating these projects confuses the central issues at stake in both, and makes the job of (...) evaluating either unnecessarily burdensome. Clarifying this helps identify the genuine metaphysical implications of the individuality thesis, which serves as an exemplar of scientifically informed metaphysics. (shrink)

Of those who believe that biological species are real, the dominant metaphysics of species is that they are individuals. While the arguments for this view have been thoroughly criticized in the last quarter thirty years, comparatively less effort has been spent trying to show that the view is actually false. My primary concern in the present paper is to detail a metaphysical problem for the species-as-individuals thesis that should at least give potential adherents great pause. Second, I will sketch a (...) “deflationary” approach to the metaphysics of species which requires us to swallow fewer contentious philosophical claims and yet still accommodate the intuitions that species are real.

Some astronomers believe that we have discovered that Pluto is not a planet. I contest this assessment. Recent discoveries of trans-Neptunian Pluto-sized objects do not require that we exclude Pluto from the planets. But the obvious alternative, that classificatory revision is a matter of arbitrary choice, is also unpalatable. I argue that this classificatory controversy — which I compare to the controversy about the classification of the platypus — illustrates how our classificatory practices are laden with normative commitments of a (...) distinctive kind. I argue that the “norm-ladenness” of classification has philosophically significant ramifications for how we think about scientific disputes and debates in the metaphysics of classification such as the monism/pluralism debate.

A number of philosophers in recent years have maintained that H. L. A. Hart in The Concept of Law propounded an expressivist account of the semantics of the legal statements that are uttered from the internal viewpoint of the people who run the institutions of legal governance in any jurisdiction. Although the primary aim of this article is to attack the attribution of that semantic doctrine to Hart, the article will begin with some metaphysical matters—the matters of reductionism and naturalism—that (...) often lie behind the development of expressivist approaches to the semantics of normative discourse. After briefly exploring those metaphysical concerns (to which I will return later), the article will begin its main discussion by rehearsing the distinction between the semantics and the pragmatics of utterances. It will then delineate the doctrine of expressivism which the aforementioned philosophers have in mind when they ascribe that doctrine to Hart. Although I will make reference to a few such philosophers, I will focus chiefly on an article by Kevin Toh that has been the fountainhead of all the subsequent attributions of expressivism to Hart. As will be argued herein, Toh and like‐minded philosophers have gone astray in imputing to Hart a semantic version of expressivism. Notwithstanding that Hart’s theory of law can aptly be characterized as expressivist, that characterization is appropriate only when expressivism is understood as an account of the pragmatics of legal statements rather than as an account of their semantics.

The world contains many different types of ecosystems. This is something of a commonplace in biology and conservation science. But there has been little attention to the question of whether such ecosystem types enjoy a degree of objectivity—whether they might be natural kinds. I argue that traditional accounts of natural kinds that emphasize nomic or causal–mechanistic dimensions of “kindhood” are ill-equipped to accommodate presumptive ecosystemic kinds. In particular, unlike many other kinds, ecosystemic kinds are “anchored” to the contingent character of (...) species and higher taxa and their abiotic environments. Drawing on Slater (Br J Philos Sci 66(2):375–411, 2015a), I show how we can nevertheless make room for such contingent anchoring in an account of natural kinds of ecosystems kinds. (shrink)

Philosophy & Social Criticism, Volume 48, Issue 4, Page 473-483, May 2022. In my recent book Freedom of Expression as Self-Restraint, I expound and defend the moral principle of freedom of expression. This article recounts a few of the main strands of the exposition in that book, and it touches upon the justification for the principle of freedom of expression. Supplementing the abstract ideas broached in the article are several illustrative examples that render the abstractions more accessible.

This paper seeks to clarify and defend the proposition that moral realism is best elaborated as a moral doctrine. I begin by upholding Ronald Dworkin’s anti-Archimedean critique of the error theory against some strictures by Michael Smith, and I then briefly suggest how a proponent of moral realism as a moral doctrine would respond to Smith’s defense of the Archimedeanism of expressivism. Thereafter, this paper moves to its chief endeavor. By differentiating clearly between expressivism and quasi-realism, the paper highlights both (...) their distinctness and their compatibility. In so doing, it underscores the affinities between Blackburnian quasi-realism and moral realism as a moral doctrine. Finally, this paper contends—in line with my earlier work on these matters—that moral realism as a moral doctrine points to the need for some reorienting of meta-ethical enquiries rather than for the abandoning of them.

A number of influential biologists are currently pursuing efforts to restore previously extinct species. But for decades, philosophers of biology have regarded “de-extinction” as conceptually incoherent. Once a species is gone, it is gone forever. We argue that a range of metaphysical, biological, and ethical grounds for opposing de-extinction are at best inconclusive and that a pragmatic stance that allows for its possibility is more appealing.

This paper first recapitulates the objections by H.L.A. Hart to the ways in which John Austin’s command model of law obfuscated the importance and the very existence of power-conferring laws. Although those objections are familiar in the world of contemporary legal philosophy, their insightfulness is highlighted here because they contrast so sharply with Hart’s own neglect of power-conferring laws at some key junctures in his theorizing. In the second half of this paper, I ponder a few of the junctures where (...) Hart failed to heed the admonitions which he had so deftly leveled against Austin. (shrink)

The papers included in this special issue were selected from a series of three interdisciplinary workshops titled Species in the Age of Discordance. Participants including philosophers, phylogeneticists, systematists, population geneticists, invasion biologists, historians, social scientists, botanists, herpetologists, ichthyologists, and microbiologists, among others, were asked to consider species in the context of discordance. The sense of “discordance” was left intentionally ambiguous in the call for abstracts, as our goal was to examine this question from many different perspectives, to seek out connections (...) across disciplines, to think about the different ways discordance surrounding species is conceived, and to ascertain how the varieties of discordance might inform each other.

In this wide-ranging investigation of leading issues in contemporary legal and political philosophy, distinguished philosophers and legal theorists tackle issues such as the rights of animals, the role of public-policy considerations in legal reasoning, the appropriateness of compensation as a means of rectifying mishaps and misdeeds, the extent of individuals' responsibility for the consequences of their choices, and the culpability of failed attempts to commit crimes.

In Albert Camus and the Political Philosophy of the Absurd: Ambivalence, Resistance, and Creativity, Matthew H. Bowker takes an interdisciplinary approach to Albert Camus’ political philosophy by reading absurdity itself as a metaphor for the psychosocial dynamics of ambivalence, resistance, integration, and creativity. Decoupling absurdity from its ontological aspirations and focusing instead on its psychological and phenomenal contours, Bowker discovers an absurdist foundation for ethical and political practice.

This article defends my 2011 book “The Ethics of Capital Punishment” against the thoughtful critiques written by Carol Steiker and John Danaher respectively. It does not attempt to respond to every point of contention in the two critiques, but concentrates instead on a few of the main points from each of them.

Consequentialist doctrines have often been criticized for their excessive demandingness, in that they require the thorough instrumentalization of each person’s life as a vehicle for the production of good consequences. In turn, the proponents of such doctrines have often objected to what they perceive as the irrationality of the demandingness of deontological duties. In this paper, I shall address objections of the latter kind in an effort to show that they are unfounded. My investigation of this matter will unfold by (...) reference to a scenario that strikingly and concretely exemplifies the demandingness of deontological duties. That scenario, which involves a situation of torture (specifically, placatory torture – in other words, torture undertaken for the purpose of appeasing people who have demanded that it be administered), will serve as a springboard for my endeavor to vindicate the rationality of deontological absolutes and will help to illuminate the endeavor’s practical implications.

This book brings together contributions from seventeen of the world's foremost legal and political philosophers to examine the lasting influence of H.L.A. Hart. The essays explore the major subjects of Hart's work: general jurisprudence, criminal responsibility, rights, justice, causation and the foundations of liberalism.

I spell out and update the individuality thesis, that species are individuals, and not classes, sets, or kinds. I offer three complementary presentations of this thesis. First, as a way of resolving an inconsistent triad about natural kinds; second, as a phylogenetic systematics theoretical perspective; and, finally, as a novel recursive account of an evolved character. These approaches do different sorts of work, serving different interests. Presenting them together produces a taxonomy of the debates over the thesis, and isolates ways (...) it has been productive. This goes to the larger point of this paper: a defense of the individuality thesis in terms of its utility, and an update of it in light of recent theoretical developments and empirical work in biology.

Ronald Dworkin has long criticized legal positivists for their efforts to distinguish between legal and non-legal standards of conduct that are incumbent on people. Recently, Dworkin has broached this criticism in his hostile account of the debates between Incorporationist Legal Positivists and Exclusive Legal Positivists. Specifically, he has maintained that Incorporationists cannot avoid the unpalatable conclusion that the axioms and theorems of arithmetic are legal norms. This article shows why such a conclusion is indeed avoidable and why Dworkin's criticism is (...) therefore wide of the mark. (shrink)
