The value of biodiversity is usually confused with the value of biological resources, both actual and potential. A sharp distinction between biological resources and biodiversity offers a clearer insight into the value of biodiversity itself and therefore the need to preserve it. Biodiversity can be defined abstractly as the differences among biological entities. Using this definition, biodiversity can be seen more appropriately as: (a) a necessary precondition for the long term maintenance of biological resources, and therefore, (b) an essential environmental (...) condition. Three values of biodiversity are identified and arranged in a hierarchy: (1) the self-augmenting phenomenon of biodiversity maintains (2) the conditions necessary for the adaptive evolution of species and higher taxa, which in turn is necessary for providing humans with (3) a range of biological resources in the long term. Two broad policy implications emerge: increments of biodiversity should not be traded off against biological resources as if they were the same, and the conservation of biodiversity should be a constraint on the public interest, not a goal in service of the public interest.

Paul M. Pietroski presents an ambitious new account of human languages as generative procedures that respect substantive constraints. He argues that meanings are neither concepts nor extensions, and sentences do not have truth conditions; meanings are composable instructions for how to access and assemble concepts of a special sort.

Governments of all nations presume they possess full discretionary policymaking powers over the lands and waters within their geopolitical boundaries. At least one global environmental issue—the rapid loss of the world’s biodiversity, the sixth major mass extinction event in geological time—challenges the legitimacy of this presumption. Increment by increment, the present generation is depleting the world’s biodiversity by way of altering species’ habitats for the sake of short term economic gain. When biodiversity is understood as an essential environmental condition—essential in (...) the long term because it is the source of the biological resources upon which humans depend—then the strongly differential distribution of benefits and burdens between generations raises an issue of intergenerational justice. We receive the short-term benefits of economic development; future generations will receive the resulting burden of a biosphere in which one of the life-support systems necessary for humanity will have been compromised. Using Ronald Dworkin’s conceptions of distributive justice, it can be demonstrated that constitutional constraints on the discretionary powers of governments, for the sake of intergenerational justice, are entirely consistent with central tenets of liberal democracy. As a result, we should abandon to some extent the presumption that governments have full jurisdiction over the lands and waters within their boundaries. (shrink)

In _Matter and Consciousness_, Paul Churchland presents a concise and contemporary overview of the philosophical issues surrounding the mind and explains the main theories and philosophical positions that have been proposed to solve them. Making the case for the relevance of theoretical and experimental results in neuroscience, cognitive science, and artificial intelligence for the philosophy of mind, Churchland reviews current developments in the cognitive sciences and offers a clear and accessible account of the connections to philosophy of mind. For (...) this third edition, the text has been updated and revised throughout. The changes range from references to the iPhone's "Siri" to expanded discussions of the work of such contemporary philosophers as David Chalmers, John Searle, and Thomas Nagel. Churchland describes new research in evolution, genetics, and visual neuroscience, among other areas, arguing that the philosophical significance of these new findings lies in the support they tend to give to the reductive and eliminative versions of materialism. Matter and Consciousness, written by the most distinguished theorist and commentator in the field, offers an authoritative summary and sourcebook for issues in philosophy of mind. It is suitable for use as an introductory undergraduate text. (shrink)

Eliminative materialism is the thesis that our common-sense conception of psychological phenomena constitutes a radically false theory, a theory so fundamentally defective that both the principles and the ontology of that theory will eventually be displaced, rather than smoothly reduced, by completed neuroscience. Our mutual understanding and even our introspection may then be reconstituted within the conceptual framework of completed neuroscience, a theory we may expect to be more powerful by far than the common-sense psychology it displaces, and more substantially (...) integrated within physical science generally. My purpose in this paper is to explore these projections, especially as they bear on (1) the principal elements of common-sense psychology: the propositional attitudes (beliefs, desires, etc.), and (2) the conception of rationality in which these elements figure.

Over the past decade or so political leaders around the world have begun to apologize for, and even seek reconciliation between perpetrators and victims of large-scale moral wrongs such as slavery, campaigns of ethnic cleansing, and official regimes of racial segregation. The South African Truth and Reconciliation Commission (TRC) is probably the most well-known example of such political efforts to effect what might be called moral healing within and between nations. In this essay, I canvass various senses of reconciliation, clarifying (...) which are appropriate for understanding these recent political efforts to heal the wounds caused by state-sanctioned moral atrocities. I argue that interpersonal reconciliation is not likely to be a promising model for understanding political efforts to achieve moral closure for large-scale wrongs, and I close with some worries about the efficacy of state-sponsored attempts to reconcile victims to their wrongdoers.

_ Source: _Volume 94, Issue 3, pp 301 - 331 The idea that we can understand key aspects of the metaphysics of consciousness by understanding conscious states as having a _presentational_ character plays an essential role in the phenomenological tradition beginning with Brentano and Husserl. In this paper, the author explores some potential consequences of this connection for contemporary discussions of the ontology of consciousness in the world. Drawing on Hintikka’s analysis of epistemic modality, the author argues that the essential (...) presentational character of consciousness can be seen as accounting for the familiar failure of substitutivity of identicals in intensional contexts of conscious presentation and further provides for an ontology of conscious presentation that avoids metaphysically problematic commitments to “special” intentional objects. The author next considers how the irreducibility of intensional contexts, if grounded in the presentational character of consciousness, also may provide for a kind of irreducibility of the “first-person” perspective to third-person or objective description across possible worlds. Finally, drawing on Chalmers’ “two-dimensionalist” semantic framework, the author argues that attention to the presentational aspect of consciousness as thus understood, while it provides significant motivation for the existence of the “hard problem” of the irreducibility of consciousness to physical and structural description, is nevertheless consistent with a globally monist, rather than dualist, ontology.

Electronic health record (EHRs) have largely replaced obsolete paper medical charts. This replacement has produced an increased demand on physicians’ time and has compromised efficiency. In an attempt to overcome this perceived obstacle to productivity, physicians turned to medical scribes to perform the work required by EHRs. In doing so, they have introduced an uninvited participant in the physician-patient relationship and compromised patients’ confidentiality. Scribes may be a successful work around for physicians frustrated by EHRs, but patients’ confidentiality should not (...) be sacrificed in the process. (shrink)

In this comment on Yli-Vakkuri and Hawthorne's illuminating book, Narrow Content, I address some issues related to externalist conceptions of linguistic meaning.

For the uninitiated, there are two major tendencies in the modeling of human cognition. The older, tradtional school believes, in essence, that full human cognition can be modeled by dividing the world up into distinct entities -- called __symbol s__-- such as “dog”, “cat”, “run”, “bite”, “happy”, “tumbleweed”, and so on, and then manipulating this vast set of symbols by a very complex and very subtle set of rules. The opposing school claims that this system, while it might be good (...) at concluding that Paris is the capital of France or that there must be blood flowing in the left-rear leg of a cow, can never capture the full measure -- indeed, the essence -- of human cognition. For them, the essential features of cognition emerge from the combined effects of myriad, tiny actions far below the surface of consciousness. This is the camp to which Paul Churchland belongs.

The purported failures of ergodic theory are shown to arise from misconception of the functions served by scientific explanation. In fact, the predictive failures of ergodic theory are precisely its points of greatest physical utility, where genuinely new knowledge about actual physical systems can be obtained, once the links between explanation and reconstructive estimation are recognized.

Chomsky’s (1995, 2000a) Minimalist Program (MP) invites a perspective on semantics that is distinctive and attractive. In section one, I discuss a general idea that many theorists should find congenial: the spoken or signed languages that human children naturally acquire and use— henceforth, human languages—are biologically implemented procedures that generate expressions, whose meanings are recursively combinable instructions to build concepts that reflect a minimal interface between the Human Faculty of Language (HFL) and other cognitive systems. In sections two and three, (...) I develop this picture in the spirit of MP, in part by asking how much of the standard Frege-Tarski apparatus is needed in order to provide adequate and illuminating descriptions of the “concept assembly instructions” that human languages can generate. I’ll suggest that we can make do with relatively little, by treating all phrasal meanings as instructions to assemble number-neutral concepts that are monadic and conjunctive. But the goal is not to legislate what counts as minimal in semantics. Rather, by pursuing one line of Minimalist thought, I hope to show how such thinking can be fruitful. (shrink)

Tumor suppressor protein 53 (p53) plays a central role in the control of genome stability, acting primarily through the transcriptional activation of stress‐response genes. However, many p53 binding sites are located at genomic locations with no obvious regulatory‐link to known stress‐response genes. We recently discovered p53 binding sites within retrotransposon‐derived elements in human and mouse subtelomeres. These retrotransposon‐derived p53 binding sites protected chromosome ends through transcription activation of telomere repeat RNA, as well as through the direct modification of local chromatin (...) structure in response to DNA damage. Based on these findings, I hypothesize that a class of p53 binding sites, including the retrotransposon‐derived p53‐sites found in subtlomeres, provide a primary function in genome stability by mounting a direct and local protective chromatin‐response to DNA damage. I speculate that retrotransposon‐derived p53 binding sites share features with telomere‐repeats through an evolutionary drive to monitor and maintain genome integrity. (shrink)

Paul M. Pietroski, University of Maryland I had heard it said that Chomsky’s conception of language is at odds with the truth-conditional program in semantics. Some of my friends said it so often that the point—or at least a point—finally sunk in.

Modified Theistic Activism is the view that abstract objects not essentially possessed by God fall under God’s creative activity in one way or another. Michelle Panchuk has argued that this position succumbs to the bootstrapping problem such that God is and is not logically prior to his properties—an incoherent and necessarily false state of affairs. In this essay we respond to Panchuk by arguing that our neo-Aristotelian account of substance and property possession successfully avoids the bootstrapping problem. Moreover, her own (...) neo-Augustinian account of universals contains many conceptual deficiencies and ultimately succumbs to an epistemic iteration of the bootstrapping problem. Finally, we argue that the reasons provided for thinking only created beings need universals to ground character is unmotivated. In clarifying and defending our position, our hope is to bury once and for all the familiar claim that traditional theists cannot be realists with respect to abstract objects because of divine bootstrapping.

Upon Brexit, the United Kingdom chose to follow the path of EU data protection and remain tied to the requirements of the General Data Protection Regulation (GDPR). It even enacted the GDPR into its domestic law. This Article evaluates five models relating to preference change, demonstrating how they identify different dimensions of Brexit while providing a rich explanation of why a legal system may or may not reject an established transnational legal order. While market forces and a “Brussels Effect” played (...) the most significant role in the decision of the UK government to accept the GDPR, important nonmarket factors were also present in this choice. This Article’s models of preference change are also useful in thinking about the likely extent of the UK’s future divergence from EU data protection. (shrink)

Proper recognition came belatedly to the work of Karl Popper. The novelty and power of his comprehensive philosophy went largely unnoticed for decades, his views being misapprehended, to the extent they were apprehended at all, as an uncompelling variation on the dominant Positivist theme. In the past two decades, however, recognition has become widespread. He can lay claim to being the initial figure in a vital and flourishing tradition in the contemporary literature; his views find expression even in undergraduate curricula; (...) and he finds himself the welcome subject of a two-volume issue in the Schilpp series, The Library of Living Philosophers. The appearance of this collection is the occasion of this notice.Unfortunately, the spectre of misapprehension surrounds Popper still, and haunts what should have been some of the most interesting pages in this collection. At issue here is Popper's conception of rational scientific methodology, a conception which has received substantial criticism from inductivist and anti-inductivist quarters alike. Partly from conviction, and partly for the sake of argument, I shall adopt the latter viewpoint in this essay. My sympathies, however, will be with his critics. (shrink)

Domjan, Cusato & Villarreal's target article is reviewed in the context of historical difficulty for learning studies in discriminating between learned and unlearned components of behavior. The research surveyed in the target article meets the criterion of differentiating between some learned and the unlearned aspects of social behavior, with Pavlovian conditioning shown repeatedly as a route by which reproductive and aggressive behavior is modulated.
