Early executive function skills reliably predict school readiness and future academic success. While children’s skills undergo rapid development during the transition to formal schooling, it remains unclear the extent to which schooling exerts a unique influence on the accelerated development of EF and academic skills during the early years of schooling. In the present study, a quasi-experimental technique known as the school cutoff design was used to examine whether same-aged children who made vs. missed the age cutoff for school entry (...) significantly differed on EF, reading, and math outcomes. Data from 166 pre-k, kindergarten, and first grade children from a longitudinal study of literacy development were analyzed. Children were assessed on EF, reading, and math skills in fall and spring. Results revealed unique effects of kindergarten, but not first grade, on growth in EF and reading over and above the effect of age. Schooling was unrelated to growth in math. Because kindergarten represents the first year of elementary school and children’s first exposure to a formal schooling environment, kindergarten schooling may be uniquely positioned to produce greater gains in academic and behavioral outcomes compared to other grades.

But with the member of a Nonconforming or self-made religious community, how different!

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.

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.

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)

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.

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.

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.

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.

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)

Every problem of dirty hands is a moral conflict in which a highly unpalatable course of conduct is chosen for the sake of fulfilling a stringent moral duty, and in which either the chosen course of conduct is evil or else it would have been evil in the absence of the exigent circumstances to which it is a response. To support this conception of problems of dirty hands, this paper endeavors to elucidate the nature of moral conflicts and the nature (...) of evil. (shrink)

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.

This essay argues against the commonly held view that "ought" implies "can" in the domain of morality. More specifically, I contest the notion that nobody should ever be held morally responsible for failing to avoid the infliction of any harm that he or she has not been able to avoid through all reasonably feasible precautions in the carrying out of some worthwhile activity. The article explicates the concept of a moral right in order to show why violations of moral rights (...) can occur even when no one has acted wrongfully in any fashion. In so doing, it will effectively be maintaining that strict liability (i.e., liability irrespective of the presence or absence of culpability) exists in morality as well as in law. When we take account of the distinction between exoneration and extenuation, we can see that scrupulously thorough precautions are never sufficient to constitute an excuse in morality. Having made that point with some extended examples, the article goes on to consider a number of possible objections - objections that lead into discussions of some basic distinctions within moral philosophy and some central principles within deontic logic.

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)

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)

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..

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.

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)

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)

In Legality Scott Shapiro seeks to provide the motivation for the development of his own elaborate account of law by undertaking a critique of H.L.A. Hart's jurisprudential theory. Hart maintained that every legal system is underlain by a rule of recognition through which officials of the system identify the norms that belong to the system as laws. Shapiro argues that Hart's remarks on the rule of recognition are confused and that his model of lawis consequently untenable. Shapiro contends that a (...) new approach is vital for progress in the philosophy of law and, with his lengthy presentation of his own Planning Theory of Law, he aspires to pioneer just such an approach. Except for a very terse observation in the final main section, this article does not directly assess the strengths and shortcomings of Shapiro's piquant planning theory. Instead, I defend Hart against Shapiro's charges and thereby undermine the motivation for the development of the planning theory. (shrink)

This chapter contains section titled: The Obligation‐to‐Obey‐the‐Law What the Law Claims Matters of Form References Further Reading.

RÉSUMÉJe soulève des questions concernant l'approche volontariste défendue par Chakravartty à l’égard des positions : supposant que nous reconnaissons une hiérarchie des positions, la position volontariste peut être à la fois vraie et trompeuse en ce qui concerne la viabilité pratique de certains débats dans le domaine de la philosophie des sciences, en particulier le débat sur le réalisme scientifique ou sur la façon de «naturaliser» la métaphysique.

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.

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)

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.
