We prove that the problem of determining the minimum propositional proof length is NP- hard to approximate within a factor of 2 log 1 - o(1) n . These results are very robust in that they hold for almost all natural proof systems, including: Frege systems, extended Frege systems, resolution, Horn resolution, the polynomial calculus, the sequent calculus, the cut-free sequent calculus, as well as the polynomial calculus. Our hardness of approximation results usually apply to proof length measured either by (...) number of symbols or by number of inferences, for tree-like or dag-like proofs. We introduce the Monotone Minimum (Circuit) Satisfying Assignment problem and reduce it to the problems of approximation of the length of proofs. (shrink)

Ewald Hering's color-opponent-theory is still considered one of the foundations of the visual sciences. Prior to Hering, Hermann v. Helmholtz introduced a theory of color appearance, which was based primarily on the physical aspects of the stimulus. In contrast to Helmholtz, Hering's theory strongly emphasized the subject's perception of color. As a consequence, Hering considered Helmholtz' theory inadequate. Contrary to some historical accounts, he did not object to Helmholtz's three-receptor explanation for color-mixture. Instead of Helmholtz' fundamental colors red, green, and (...) blue, Hering suggested that the colors possess opponent character: blue-yellow; red-green; and, black-white. Helmholtz, on the other hand, refused to accept Hering's theory. Finally, a student with Helmholtz, Johannes v. Kries, developed the so-called zone-theory , which combines both, Young-Helmholtz's and Hering's theory at different stages of the visual information processing system. (shrink)

BackgroundTo prevent the planet from catastrophic global warming a reduction of greenhouse gas emissions to net zero is required. Thus, divestment from fossil fuels must be a strategic interest for health insurers. The aim of this study was to analyse the implementation of environmental, social and governance criteria in German private health insurers’ investments.MethodsIn 2019 a survey about ESG strategies was sent to German private health insurance companies. The survey evaluated investment strategies and thresholds for the exclusion of sectors and (...) business practices, as well as company strategies for sustainable business development.FindingsGiven their business reports, German private health insurers manage assets of more than €350 billion. 11 of 40 insurance companies provided quantitative data, 10 refused to answer. According to quantitative data, €66 billion of assets is managed according to any ESG criteria; this equals an average of 76% of each company’s bonds. None of these insurers excluded the production and sale of fossil fuels. All excluded coal mining but only at high thresholds. For €226 billion, no data were provided.InterpretationThe findings are in contrast to the expected intrinsic economic interest of the insurers to stop global warming and improve public health. The majority of assets are managed in a highly problematic manner, especially the absence of capital allocated in fields contrary to medical ethics cannot be presumed. Lack of transparency is a major problem that limits clients in choosing the insurer who has the most advanced ESG criteria. (shrink)

Michael Ruse's rejection of religious belief is questioned at two levels. First, on the metaethical level of analysis, evolutionary ethics cannot account for moral behavior that is based on a “strong version” of the Love Command. Second, agnosticism is discussed as a form of belief. Insights from religious forms of life that are inclusive, pluralistic, and expansive are contrasted with exclusivistic, closed, and fundamentalist forms of religion in order to develop criteria for “genuine religion.” Theistic agnosticism is presented as (...) a prolegomena to belief.

tephen Jay Gould's Wonderful Life: The Burgess Shale and the Nature of History , has become something of a watershed for those who study contingency and complexity, especially applied to organisms, societies, and history, and discussions of it can be found in many works. Walter Fontana and Leo Buss, for example, ask in the title of their chapter "What Would Be Conserved If 'The Tape Were Played Twice'?" This is a direct reference to Gould's suggestion in Wonderful Life that if (...) the tape of life were rewound to the time of the organisms found in the Canadian outcrop known as the Burgess Shale, dated to about 530 million years ago, and replayed with a few contingencies tweaked here and there, humans would most likely never have evolved.

In lieu of an abstract, here is a brief excerpt of the content:Philosophy and Literature 25.2 (2001) 251-277 [Access article in PDF] Hans Christian Andersen's Fish Out of Water Nancy Easterlin I Now that Darwinian literary criticism is on the horizon, the natural human tendency to codify manifests itself in calls to summarize succinctly what such an approach entails. Though clarity is always to be praised, bioevolutionary critics need to guard against the reductiveness that has beleaguered attempts at a scientifically (...) grounded literary criticism since the early twentieth century; most especially, we should think twice about limiting the interpretation of complex and varied works to selected sociobiological themes divorced from other biocultural considerations. David Sloan Wilson makes much the same point to students of evolution when he quotes Celia Heyes in a recent review of Evolutionary Psychology, David Buss's new textbook: "When I first encountered the term 'evolutionary psychology,' I thought it referred to the study of how mind and behavior evolved. But I was mistaken. In current usage, 'evolutionary psychology' refers exclusively to research on human mentality and behavior, motivated by a very specific, nativist-adaptationist interpretation of how evolution operates." 1If, as D. S. Wilson suggests, evolutionary psychology thus narrowly defined threatens to produce a limited understanding of human mind and behavior and, in the process, fragment the discipline of psychology further, how much less potentially productive is such an approach for those of us whose central objects of study, cultural artifacts, are as the products of behavior even further removed from the study of mind? Leda Cosmides and John Tooby are most explicit about the falsity of assuming that psychological adaptations determine behavior. This being so, it seems impossible that such adaptations could determine the [End Page 251] meaning of artworks, which are themselves the products of complex human behaviors. As I hope this discussion of Hans Christian Andersen's "Little Mermaid" will demonstrate, an approach to aesthetics strictly following the lead of evolutionary psychology as currently defined, while supplying valuable general insights about the motives for artistic behaviors and the cognitive processes engaged in them, cannot by itself inform us about the meaning of individual artworks. This is a crucial issue, since interpretation is the fundamental pursuit of scholars in fields like mine, literary studies.Putting the question of interpretive frutifulness aside for the moment, it can be said unequivocally that criticism that fails to be sensitive to mutation and change is not properly Darwinian. Evolutionary psychology and sociobiology themselves maintain that our psychic architecture is comprised of domain-specific competences; the result, as E. O. Wilson points out, is that the human mind is not designed to understand reality but is instead an instrument for survival and reproduction. 2 "Natural selection," says Michael Ruse, "works in a gerry-building fashion, making do with what it has at hand." 3 Though our various evolved competences cannot be radically dissonant if the organism is to survive, neither are they logically integrated, neatly interlocking "modules." Under some environmental conditions, specific adaptations or epigenetic rules are not likely to produce a competitive advantage while other very different adaptations certainly will, and hence the flexibility of the organism ensures its survival. If, for instance, I place my coffee mug down on my desk and at that exact moment two cars collide on the street outside, familiarity with my environment militates against invocation of the causal rule, even though such a rule is incontrovertibly part of our adapted psychology. 4 Knowing, then, that we share an evolved psychic architecture whose patient excavation, so to speak, will result in a progressively better defined concept of human nature, and knowing too that the behavior of human beings as writers as well as other kinds of agents varies under divergent environmental conditions, Darwinian criticism should be sensitive to the complex relationship between individual adaptations, the total array of adaptations, subjective cognitive processes, and environmental circumstances that give literary works enduring significance. In contemplating literary meaning, as with aesthetics, we should be mindful that epigenesis is not simply the instantiation of epigenetic rules. 5 Ideally, literary interpretation should be informed by the evolution of mind, behavior, and...

An emerging class of theories concerning the functional structure of the brain takes the reuse of neural circuitry for various cognitive purposes to be a central organizational principle. According to these theories, it is quite common for neural circuits established for one purpose to be exapted (exploited, recycled, redeployed) during evolution or normal development, and be put to different uses, often without losing their original functions. Neural reuse theories thus differ from the usual understanding of the role of neural plasticity (...) (which is, after all, a kind of reuse) in brain organization along the following lines: According to neural reuse, circuits can continue to acquire new uses after an initial or original function is established; the acquisition of new uses need not involve unusual circumstances such as injury or loss of established function; and the acquisition of a new use need not involve (much) local change to circuit structure (e.g., it might involve only the establishment of functional connections to new neural partners). Thus, neural reuse theories offer a distinct perspective on several topics of general interest, such as: the evolution and development of the brain, including (for instance) the evolutionary-developmental pathway supporting primate tool use and human language; the degree of modularity in brain organization; the degree of localization of cognitive function; and the cortical parcellation problem and the prospects (and proper methods to employ) for function to structure mapping. The idea also has some practical implications in the areas of rehabilitative medicine and machine interface design. (shrink)

Michael G. Titelbaum presents a new Bayesian framework for modeling rational degrees of belief—the first of its kind to represent rational requirements on agents who undergo certainty loss.

The authors of this volume discuss the relevance and influence of various Old and New Testament documents, and early Christian and Jewish texts in terms of their impact in shaping the moral character, identity, and behaviour of the specific communities in which they were produced as well as their ethical application throughout the centuries. Against a narrow understanding of ethics, the term "application" is not used to analyse the texts of the Bible as step-by-step manuals for moral conduct. Rather, the (...) contributors engage with biblical texts within the framework of a complex hermeneutical process of application of the relevance of these texts in contemporary ethical discourse.

Machine learning algorithms pervade contemporary society. They are integral to social institutions, inform processes of governance, and animate the mundane technologies of daily life. Consistently, the outcomes of machine learning reflect, reproduce, and amplify structural inequalities. The field of fair machine learning has emerged in response, developing mathematical techniques that increase fairness based on anti-classification, classification parity, and calibration standards. In practice, these computational correctives invariably fall short, operating from an algorithmic idealism that does not, and cannot, address systemic, Intersectional (...) stratifications. Taking present fair machine learning methods as our point of departure, we suggest instead the notion and practice of algorithmic reparation. Rooted in theories of Intersectionality, reparative algorithms name, unmask, and undo allocative and representational harms as they materialize in sociotechnical form. We propose algorithmic reparation as a foundation for building, evaluating, adjusting, and when necessary, omitting and eradicating machine learning systems. (shrink)

Possibility offers a new analysis of the metaphysical concepts of possibility and necessity, one that does not rely on any sort of "possible worlds." The analysis proceeds from an account of the notion of a physical object and from the positing of properties and relations. It is motivated by considerations about how we actually speak of and think of objects. Michael Jubien discusses several closely related topics, including different purported varieties of possible worlds, the doctrine of "essentialism," natural kind (...) terms and alleged examples of necessity a posteriori. The book also offers a new theory of the functioning of proper names, both actual and fictional, and the discussion of natural kind terms and necessity a posteriori depends in part on this theory.

To accept that cognition is embodied is to question many of the beliefs traditionally held by cognitive scientists. One key question regards the localization of cognitive faculties. Here we argue that for cognition to be embodied and sometimes embedded, means that the cognitive faculty cannot be localized in a brain area alone. We review recent research on neural reuse, the 1/f structure of human activity, tool use, group cognition, and social coordination dynamics that we believe demonstrates how the boundary between (...) the different areas of the brain, the brain and body, and the body and environment is not only blurred but indeterminate. In turn, we propose that cognition is supported by a nested structure of task-specific synergies, which are softly assembled from a variety of neural, bodily, and environmental components (including other individuals), and exhibit interaction dominant dynamics.

It is of fundamental importance to understand how the individual processes of gene expression, transcription, and translation, as well as mRNA and protein stability, act in concert to produce dynamic cellular proteomes. We use the concept of response times to illustrate the relation between degradation processes and responsiveness of the proteome to system changes and to provide supporting experimental evidence: proteins with short response times tend to be more strongly up‐regulated after 1 hour of TNFα stimulation than proteins with longer (...) response times. Furthermore, based on process‐dependent response times, we demonstrate that synthesis and degradation act in concert to enable rapid responses. Finally, by building on a previously published data set quantifying the mammalian gene expression cascade, we speculate on how combinations of stable and unstable mRNAs and proteins may be wired to transcriptional or translational regulation to support gene function.

This paper contributes to our understanding of farm data value chains with assistance from 54 semi-structured interviews and field notes from participant observations. Methodologically, it includes individuals, such as farmers, who hold well-known positionalities within digital agriculture spaces—platforms that include precision farming techniques, farm equipment built on machine learning architecture and algorithms, and robotics—while also including less visible elements and practices. The actors interviewed and materialities and performances observed thus came from spaces and places inhabited by, for example, farmers, crop (...) scientists, statisticians, programmers, and senior leadership in firms located in the U.S. and Canada. The stability of “the” artifacts followed for this project proved challenging, which led to me rethinking how to approach the subject conceptually. The paper is animated by a posthumanist commitment, drawing heavily from assemblage thinking and critical data scholarship coming out of Science and Technology Studies. The argument’s understanding of “chains” therefore lies on an alternative conceptual plane relative to most commodity chain scholarship. To speak of a data value chain is to foreground an orchestrating set of relations among humans, non-humans, products, spaces, places, and practices. The paper’s principle contribution involves interrogating lock-in tendencies at different “points” along the digital farm platform assemblage while pushing for a varied understanding of governance depending on the roles of the actors and actants involved.

Drawing on a rich pragmatist tradition, this book offers an account of the different kinds of ‘oughts’, or varieties of normativity, that we are subject to contends that there is no conflict between normativity and the world as science describes it. The authors argue that normative claims aim to evaluate, to urge us to do or not do something, and to tell us how a state of affairs ought to be. These claims articulate forms of action-guidance that are different in (...) kind from descriptive claims, with a wholly distinct practical and expressive character. This account suggests that there are no normative facts, and so nothing that needs any troublesome shoehorning into a scientific account of the world. This work explains that nevertheless, normative claims are constrained by the world, and answerable to reason and argumentation, in a way that makes them truth-apt and objective. (shrink)

But as philosophical fashion moved away from the analytic philosophy of the 1930s, this work began to seem ahead of its time.

This highly readable new collection of thirty pieces by Michael Oakeshott, almost all of which are previously unpublished, covers every decade of his intellectual career, and adds significantly to his contributions to the philosophy of historical understanding and political philosophy, as well as to the philosophy of education and aesthetics. The essays were intended mostly for lectures or seminars, and are consequently in an informal style that will be accessible to new readers as well as to those already well (...) acquainted with Oakeshott's works. Early pieces include a long essay ‘On the Relations of Philosophy, Poetry, and Reality', and Oakeshott’s comments on ‘The Cambridge School of Political Science’ through which he himself had passed as an undergraduate. The collection also reproduces a substantial wartime essay ‘On Peace with Germany’. There are two new essays on the philosophy of education, and the essay which gives the work its title, ‘What is History?’, is just one of over half a dozen discussions of the nature of historical knowledge. Oakeshott’s later sceptical, ‘hermeneutic’, thought is also well represented by pieces such as ‘What is Political Theory?’ and ‘The Emergence of the History of Thought.’ Reviews of books by English and European contemporaries such as Butterfield, Hayek, Voegelin, and Arendt also help to place him in context more clearly than before. The book will be indispensable for all Oakeshott’s readers, no matter which area of his thought concerns them most. (shrink)

This article examines Kant′s use of the expression “fact of reason” by giving an analysis of the pseudo-mathematical method which Kant employs in the first part of the Critique of Practical Reason. It turns out that Kant′s use of this expression has nothing to do with appealing to a certain fact as being an obvious, self-evident truth. There is no need for such an appeal since the “Fundamental Law of Pure Practical Reason” is a “practical postulate” which, like a postulate (...) in geometry, is unquestionably certain. In order to realize its validity it is sufficient to know what a practical law is and on what its validity depends. The fundamental law of pure practical reason needs, in Kant′s view, a “deduction” since it is a synthetic principle a priori. But its deduction cannot be a proof since postulates neither can nor need be proved. It has to be a justification which guarantees that the use of pure reason in giving practical laws is not “transcendent”, but “immanent”. This justification has, unlike Kant′s deduction of the “Postulates of Empirical Thinking”, the systematic form of a “defence” which invalidates possible objections by showing that they themselves necessarily rest on a transcendent use of reason.

In this article we explore the different trajectories of this one drug, phenylbutazone, across two species, humans and horses in the period 1950–2000. The essay begins by following the introduction of the drug into human medicine in the early 1950s. It promised to be a less costly alternative to cortisone, one of the “wonder drugs” of the era, in the treatment of rheumatic conditions. Both drugs appeared to offer symptomatic relief rather than a cure, and did so with the risk (...) of side effects, which with phenylbutazone were potentially so severe that it was eventually banned from human use, for all but a few diseases, in the early 1980s. Phenylbutazone had been used with other animals for many years without the same issues, but in the 1980s its uses in veterinary medicine, especially in horses, came under increased scrutiny, but for quite different reasons. The focus was primarily the equity, economics, and ethics of competition in equine sports, with differences in cross-species biology and medicine playing a secondary role. The story of phenylbutazone, a single drug, shows how the different biologies and social roles of its human/animal subjects resulted in very different and changing uses. While the drug had a seemingly common impact on pain and inflammation, there were inter-species differences in the drug’s metabolism, the conditions treated, dosages, and, crucially, in intended clinical outcomes and perceptions of its benefits and risks.

Chagnon’s analysis of a well-known axe fight in the Yanomamö village of Mishimishiböwei-teri (Chagnon and Bugos 1979) is among the earliest empirical tests of kin selection theory for explaining cooperation in humans. Kin selection theory describes how cooperation can be organized around genetic kinship and is a fundamental tool for understanding cooperation within family groups. Previous analysis on groups of cooperative Lamaleran whale hunters suggests that the role of genetic kinship as a principle for organizing cooperative human groups could be (...) less important in certain cases than previously thought (Alvard Human Nature 14:129–163, 2003b). Evidence that supports a strong role for genetic kinship—groups are found to be more related than expected by chance—may be spurious because of the correlation between social structure and genetic kinship. Reanalysis of Chagnon’s data using matrix regression techniques, however, confirms that genetic kinship was the primary organizing principle in the axe fight; affinal relations were also important, whereas lineage identity explained nothing.

“The physics of representation” aims to define the word “representation” as used in the neurosciences, argue that such representations as described in neuroscience are related to and usefully illuminated by the representations generated by modern neural networks, and establish that these entities are “representations in good standing”.

This results in some hard choices: give up on the broad scope of the term in neuroscience or continue to embrace the broad, psychologically inflected sense of the term, and deny the entities generated by neural nets are representations in the relevant sense.

That there was a ‘Bacteriological Revolution’ in medicine in the late nineteenth-century, associated with the development of germ theories of disease, is widely assumed by historians; however, the notion has not been defined, discussed or defended. In this article a characterisation is offered in terms of four linked rapid and radical changes: a series of discoveries of the specific causal agents of infectious diseases and the introduction of Koch’s Postulates; a reductionist and contagionist turn in medical knowledge and practice; greater (...) authority for experimental laboratory methods in medicine; the introduction and success of immunological products. These features are then tested against developments in four important but previously neglected diseases: syphilis, leprosy, gonorrhoea and rabies. From these case-studies I conclude that the case for a Bacteriological Revolution in late nineteenth-century medicine in Britain remains unproven. I suggest that historians have read into the 1880s changes that occurred over a much longer period, and that while there were significant shifts in ideas and practices over the decade, the balance of continuities and changes was quite uneven across medicine. My argument is only for Britain; in other countries the rate and extent of change may have been different. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Ghazali and Demonstrative Science MICHAEL E. MARMURA I MEDIEVALISLA_MICtheologians subjected Aristotle's theory of the essential efficient cause to severe criticism and rejected it. This criticism and rejection finds its most forceful expression in the writings of Ghazali (al-Ghaz~li) (d. 1111).1 In his Tahafut al-Falasifa (The Incoherence of the Philosophers), he argues on logical and empirical grounds that the alleged necessary connection between what is habitually regarded as the (...) natural efficient cause and its effect cannot be proven. He does not, however, take an agnostic stand on this question but proceeds to affirm two points: (1) that there is no causal agency in natural things; (2) that all natural events are the direct creation of God. Ghazali, moreover, does not confine such divine action to the realm of the inanimate and the irrational, in his al-Iqtis.~d fi-l-Ftiqad (The Golden Mean of Belief), he affirms the doctrine that the individual human act, like any other occurrence in the world, is also the direct creation of God. Causal efficacy resides in God alone. But the divine act, for Ghazali, is not an essential act. It does not proceed as the necessary consequence of divine essence. It is the arbitrary decree of the divine will, an attribute coeternal, but not identical with divine essence. Ghazali thus denies essential action altogether. In all this, he gives expression to the occasionalism of the Islamic school of dogmatic theology (kal~m) to which he belonged, the Ashcarite school. Ghazali had also a keen interest in logic. He wrote logical treatises for his fellow theologians, encouraging them to master this art as a tool to rebutt their doctrinal opponents. The~ treatises, in the main, sum up and explain the logic used by the Islamic philosophers--a logic that reflects the Stoic and Aristotelian traditions. Ghazali recognizes formal logic to be philosophically neutral, and hence in no way conflicting with his theology." He does not confine himself to formal logic in these expositions, however, but discusses Aristotelian demonstration. And it is in his statements on demonstration that we seem to be confronted with paradox. Demonstrative science, as understood by the Islamic philosophers, rests on the theory of essential causes and functions in terms of it. Indeed, in his reply to Ghazali's rejection of essential efficient causes in nature, Averroes (Ibn Rushd) (d. 1198) argues Texts frequently referred to in the notes will be abbreviated as follows: Demonstration: Ibn Sin~, Al-Shifa~; Logic V.; Demonstration, ed.

We would have no true knowledge; at best, only opinion. 3For this staunch defender of Aristotle, the theory of natural efficient causality constitutes a necessary condition for demonstrative science. Yet Ghazali in his writings does not deny the claim that demonstration gives us certain knowledge about the natural order. On the contrary, he seems to be affirming this in both his Tahdfutand the logical treatise he appended to this work, Mi~jdral-CIlm(The Standardfor Knowledge).If Ghazali does in fact uphold this claim for demonstration, then he must either deny that the theory of essential efficient causality is a necessary condition for demonstrative science, or fall into contradiction. At first glance, Ghazali's position in the Micy~r,where he gives his most comprehensive treatment of demonstration, is highly ambiguous and suggests contradiction. He seems for the most part to be reproducing the essentials of the Aristotelian demonstrative theory. Although in one section he reaffirms his rejection of necessary causal connection in nature, he nonetheless continues to use such terms as "cause," "effect," "necessity" and "certainty" in what appear to be...

One of the most foundational and continually contested questions in the cognitive sciences is the degree to which the functional organization of the brain can be understood as modular. In its classic formulation, a module was defined as a cognitive sub-system with nine specific properties; the classic module is, among other things, domain specific, encapsulated, and implemented in dedicated neural substrates. Most of the examinations—and especially the criticisms—of the modularity thesis have focused on these properties individually, for instance by finding (...) counterexamples in which otherwise good candidates for cognitive modules are shown to lack domain specificity or encapsulation. The current paper goes beyond the usual approach by asking what some of the broad architectural implications of the modularity thesis might be, and attempting to test for these. The evidence does not favor a modular architecture for the cortex. Moreover, the evidence suggests that best way to approach the understanding of cognition is not by analyzing and modelling different functional domains in isolation from the others, but rather by looking for points of overlap in their neural implementations, and exploiting these to guide the analysis and decomposition of the functions in question. This has significant implications for the question of how to approach the design and implementation of intelligent artifacts in general, and language-using robots in particular. (shrink)

Is there a single right interpretation for such cultural phenomena as works of literature, visual artworks, works of music, the self, and legal and sacred texts? In these essays, almost all written especially for this volume, twenty leading philosophers pursue different answers to this question by examining the nature of interpretation and its objects and ideals. The fundamental conflict between positions that universally require the ideal of a single admissible interpretation and those that allow a multiplicity of some admissible interpretations (...) leads to a host of engrossing questions explored in these essays: Does multiplism invite interpretive anarchy? Can opposing interpretations be jointly defended? Should competition between contending interpretations be understood in terms of truth or reasonableness, appropriateness, aptness, or the like? Is interpretation itself an essentially contested concept? Does interpretive activity seek truth or aim at something else as well? Should one focus on interpretive acts rather than interpretations? Should admissible interpretations be fixed by locating intentions of a historical or hypothetical creator, or neither? What bearing does the fact of the historical situatedness of cultural entities have on their identities?
