The relation between method, concept and theory in science is complicated. I seek to shed light on that relation by considering an instance of it in systematics: The additional challenges phylogeneticists face when reconstructing phylogeny not at a single level, but simultaneously at multiple levels of the hierarchy. How does this complicate the task of phylogenetic inference, and how might it inform and shape the conceptual foundations of phylogenetics? This offers a lens through which the interplay of method, theory and (...) concepts may be understood in systematics, which, in turn, provides data for a more general account. (shrink)

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.

Type specimens are used to designate species. What is the nature of the relation between a type specimen and the species it designates? If species names are rigid designators, and type specimens ostensively define species, then that relation is, at the very least, a close one. Levine :325–338, 2001) argues that the relationship of type specimen to a named species is one of necessity—and that this presents problems for the individuality thesis. Namely, it seems odd that a contingently selected specimen (...) should belong to a species of necessity. In considering Levine’s argument, LaPorte suggests that recognizing the distinction between de re and de dicto necessity resolves Levine’s worries. I reconsider the motivating question: does a type specimen belong of necessity to the species that it designates? In light of taxonomic cases and practice the answer is clear: definitively not. This is particularly clear in the case of re-designation of types by taxonomic decree. I explain how this helps reveal how taxonomists prioritize competing theoretical commitments, and offer a defense of the individuality thesis as applied to these particular cases. In short, I demonstrate how to misidentify a type specimen. (shrink)

Biological lineages move through time, space, and each other. As they do, they diversify, diverge, and grade away from and into one another. One result of this is genealogical discordance; i.e., the lineages of a biological entity may have different histories. We see this on numerous levels, from microbial networks, to holobionts, to population-level lineages. This paper considers how genealogical discordance impacts our study of species. More specifically, I consider this in the context of three framing questions: (1) How, if (...) at all, does genealogical discordance challenge, modify, or revise how we conceive of species? (2) How has growing appreciation of genealogical discordance impacted scientific practice? Of systematics in particular? (3) How do lineages at different levels diverge and diversify? All told, genealogical discordance enriches and complicates our taxonomic ontology, as well as the practice of reconstructing phylogenies. This presents both challenges and opportunities for the study of divergence and diversification. (shrink)

Research that involves the creation of animals with human-derived parts opens the door to potentially valuable scientific and therapeutic advances, yet invokes unsettling moral questions. Critics and champions alike stand to gain from clear identification and careful consideration of the strongest ethical objections to this research. A prevailing objection argues that crossing the human/nonhuman species boundary introduces inexorable moral confusion (IMC) that warrants a restriction to this research on precautionary grounds. Though this objection may capture the intuitions of many who (...) find this research unsettling, it relies on mistaken views of both biology and moral standing, ultimately distorting the morally relevant facts. We critically examine IMC, identify mistaken essentialist assumptions, and reframe ethical concerns. The upshot is a stronger line of objection that encourages a more inclusive and productive ethical discourse. (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)

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.

Samir Okasha argues that clade selection is an incoherent concept, because the relation that constitutes clades is such that it renders parent-offspring (reproduction) relations between clades impossible. He reasons that since clades cannot reproduce, it is not coherent to speak of natural selection operating at the clade level. We argue, however, that when species-level lineages and clade-level lineages are treated consistently according to standard cladist commitments, clade reproduction is indeed possible and clade selection is coherent if certain conditions obtain. Despite (...) clade selection's logical coherence, however, we share some of Okasha's pessimism. Whether or not clades are a unit of selection is ultimately a question of empirical support and theoretical import. (shrink)

Thomas Pradeu’s The Limits of the Self provides a precise account of biological identity developed from the central concepts of immunology. Yet the central concepts most relevant to this task are themselves deemed inadequate, suffering from ambiguity and imprecision. Pradeu seeks to remedy this by proposing a new guiding theory for immunology, the continuity theory. From this, an account of biological identity is provided in terms of uniqueness and individuality, ultimately leading to a defense of the heterogeneous organism as expressing (...) the highest degree of individuality.

Exploring whether clades can reproduce leads to new perspectives on general accounts of biological development and individuation. Here we apply James Griesemer's general account of reproduction to clades. Griesemer's account of reproduction includes a requirement for development, raising the question of whether clades may bemeaningfully said to develop. We offer two illustrative examples of what clade development might look like, though evaluating these examples proves difficult due to the paucity of general accounts of development. This difficulty, however, is instructive about (...) what a general account of development should look like and how it may usefully be applied to research problems (further suggesting a means for evaluating general accounts of development). Reproduction also requires individuation of parent and offspring. We argue that there is no special problem of individuating older and younger clades. The vagaries involved with determining when clades begin, mature, and end are precisely the same as those that arise when the same questions are asked of cells, organisms, or species. Though the question of clade reproduction and selection may still be open, the process of discovery presents new insights into old problems. (shrink)

The themes, problems and challenges of developmental systems theory as described in Cycles of Contingency are discussed. We argue in favor of a robust approach to philosophical and scientific problems of extended heredity and the integration of behavior, development, inheritance, and evolution. Problems with Sterelny's proposal to evaluate inheritance systems using his `Hoyle criteria' are discussed and critically evaluated. Additional support for a developmental systems perspective is sought in evolutionary studies of performance and behavior modulation of fitness.

In this volume, the work of British psychoanalyst D.W. Winnicott is set in conversation with some of today’s most talented psychodynamically-sensitive political thinkers. The editors and contributors demonstrate that Winnicott’s thought contains underappreciated political insights, discoverable in his reflections on the nature of the maturational process, and useful in working through difficult impasses confronting contemporary political theorists. Specifically, Winnicott’s psychoanalytic theory and practice offer a framework by which the political subject, destabilized and disrupted in much postmodern and contemporary thinking, may (...) be recentered. Each chapter in this volume, in its own way, grapples with this central theme: the potential for authentic subjectivity and inter-subjectivity to arise within a nexus of autonomy and dependence, aggression and civility, destructiveness and care. This volume is unique in its contribution to the growing field of object-relations-oriented political and social theory. It will be of interest to political scientists, psychologists, and scholars of related subjects in the humanities and social sciences. (shrink)

Despite decades of concerted efforts to communicate to the public on important scientific issues pertaining to the environment and public health, gaps between public acceptance and the scientific consensus on these issues remain stubborn. One strategy for dealing with this shortcoming has been to focus on the existence of scientific consensus on the relevant matters. Recent science communication research has added support to this general idea, though the interpretation of these studies and their generalizability remains a matter of contention. In (...) this paper, we describe results of a qualitative interview study on different models of scientific consensus and the relationship between such models and trust of science, finding that familiarity with scientific consensus is rarer than might be expected. These results suggest that consensus messaging strategies may not be effective. (shrink)

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.

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.

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

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)

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.

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.

This collection of essays forms a lively debate over the fundamental characteristics of legal and moral rights. The essays examine whether rights fundamentally protect individuals' interests or whether they instead fundamentally enable individuals to make choices.

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)

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.

What is objectivity? What is the rule of law? Are the operations of legal systems objective? If so, in what ways and to what degrees are they objective? Does anything of importance depend on the objectivity of law? These are some of the principal questions addressed by Matthew H. Kramer in this lucid and wide-ranging study that introduces readers to vital areas of philosophical enquiry. As Kramer shows, objectivity and the rule of law are complicated phenomena, each comprising a (...) number of distinct though overlapping dimensions. Although the connections between objectivity and the rule of law are intimate, they are also densely multi-faceted. (shrink)

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.

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.
