The consequentializing project relies on agentcentered value (aka agent-relative value), but many philosophers find the idea incomprehensible or incoherent. Discussions of agent-centered value often model it with a theory that assigns distinct better-than rankings of states of affairs to each agent, rather than assigning a single ranking common to all. A less popular kind of model uses a single ranking, but takes the value-bearing objects to be properties (sets of centered worlds) rather than states of affairs (sets of worlds). (...) There are rhetorical, presentational differences between these kinds of models, but are there also structural differences? Do the two kinds of models differ in their capacity to represent normative theories? Despite an initial appearance of equivalence, the two kinds of models are different. The single ranking of properties has greater representational power; its representations contain more information. The main question I address in this article is whether this extra information is useful, in the sense that it distinguishes between normative views that we think are really different, or whether it is just junk information.

Memory of past episodes provides a sense of personal identity — the sense that I am the same person as someone in the past. We present a neurological case study of a patient who has accurate memories of scenes from his past, but for whom the memories lack the sense of mineness. On the basis of this case study, we propose that the sense of identity derives from two components, one delivering the content of the memory (...) and the other generating the sense of mineness. We argue that this new model of the sense of identity has implications for debates about quasi-memory. In addition, articulating the components of the sense of identity promises to bear on the extent to which this sense of identity provides evidence of personal identity. (shrink)

What can contemporary machine learning (ML) models do? Given the proliferation of ML models in society, answering this question matters to a variety of stakeholders, both public and private. The evaluation of models' capabilities is rapidly emerging as a key subfield of modern ML, buoyed by regulatory attention and government grants. Despite this, the notion of an ML model possessing a capability has not been interrogated: what are we saying when we say that a model is able to do something? (...) And what sorts of evidence bear upon this question? -/- In this paper, we aim to answer these questions, using the capabilities of large language models (LLMs) as a running example. Drawing on the large philosophical literature on abilities, we develop an account of ML models' capabilities which can be usefully applied to the nascent science of model evaluation. Our core proposal is a conditional analysis of model abilities (CAMA): crudely, a machine learning model has a capability to X just when it would reliably succeed at doing X if it 'tried'. The main contribution of the paper is making this proposal precise in the context of ML, resulting in an operationalisation of CAMA applicable to LLMs. We then put CAMA to work, showing that it can help make sense of various features of ML model evaluation practice, as well as suggest procedures for performing fair inter-model comparisons.

I put forward an externalist theory of social understanding. On this view, psychological sense making takes place in environments that contain both agent and interpreter. The spatial structure of such environments is social, in the sense that its occupants locate its objects by an exercise in triangulation relative to each of their standpoints. This triangulation is achieved in intersubjective interaction and gives rise to a triadic model of the social mind. This model can then be used to make (...) sense of others’ observed actions. Its possession plays a vital role in the development of the capacity for false belief reasoning. The view offers an integrated account of the development of social cognition from primary intersubjectivity to level-2 perspective taking. It incorporates insights from interactionism and mindreading theories of social cognition and thus offers a way out of the stalemate between defenders of the two views. Because psychological sense making is perspectival, the frame problem does not arise for social reasoners: the perspective they bring to bear on the action that is to be interpreted constrains the information they can select to make sense of what others do.

The focus of the author’s attention has been on the emblematic sense concentration in the philosophical system of Hryhorii Skovoroda. The study aims to reveal the artistic and style features of eide emblematic formation in the texts of the Ukrainian sophist, their origin, context, and conceptual classification by the author himself. The theoretical generalizations were essentially based on the philosophical treatises and dialogues by Hryhorii Skovoroda and the studies of other scholars. To analyze the issues under scrutiny, the author (...) applied structuralist and semiotic methodology. The article highlights the emblematic sense, conveyance, and dominance in Skovoroda’s works. Emblematic forms of signification play a unique role in elucidating the anthropological, metaphysical, ethical, aesthetic, and hermeneutic dimensions of the Ukrainian poet and philosopher. Skovoroda considers emblemacity a particularly effective pictorial and verbal (iconic-conventional) type of “significative” speech, functioning as metalanguage. (shrink)

The first and preliminary part of this discussion examines Todorov's remark, in his article "Structural Analysis of Narrative" , on certain tales in the Decameron. These are advanced as dealing with a "concrete problem" which "illustrates" what Todorov "conceive[s] to be the structural approach to literature." The second part offers an alternative analysis of the Decameron tales. The third part comprises some observations, from a similar point of view, on Crime and Punishment. The anterior purpose of the whole discussion is (...) to identify at least some points where insights about "structure," in a fairly strict sense, seem to bear genuinely upon the insights of the literary critic. John Holloway, Professor of Modern English at the University of Cambridge, is the author of, among others, The Victorian Sage, The Charted Mirror, The Story of the Night, Blake: The Lyric Poetry, The Proud Knowledge, Planet of Winds, and five volumes of verse.

In lieu of an abstract, here is a brief excerpt of the content:Rehearsal and Hamilton’s “Ingredients Model” of Theatrical PerformanceDavid Davies (bio)IArtistic performances can be thought of as “doings”—things that are done—that share the following features of performances in general: they involve actions aimed at achieving some result; they are open, at least in principle, to public scrutiny and assessment; and they are usually presented to a relevantly informed public with the intention that they be appreciated and assessed, and perhaps (...) also with the intention that some practical goal be achieved. A performance can be classified as “artistic” in a descriptive (rather than normative) sense if it bears in one of the following ways upon the appreciation and evaluation of a focus of artistic appreciation:1 either (a) the performance is itself a focus of artistic appreciation, or (b) the performance plays an essential part in the artistic appreciation and evaluation of something else that is a focus of artistic appreciation by virtue of being an instance of the latter.Many performances in the performing arts are described and treated as performances of something else that is itself an artwork of some kind. We can term the latter a “performed work” and the former a “work-performance.” A work-performance, insofar as it is an instance of a performed work that bears upon its proper artistic appreciation and evaluation, qualifies as artistic in sense (b). Arguably, a work-performance can itself be an object of artistic appreciation and evaluation and thereby also qualify as artistic in sense (a).2 Where we have an artistic practice in which some acknowledged artworks are designed to be performed works, the practice qualifies as what I shall term a “performance art.” The latter is an artistic practice in which our access to, and appreciation of, works (as receivers) is at least in part mediated [End Page 23] by performances of those works. Drama, music, and dance are usually taken to be performance arts in this sense. Intuitively, our access to performed works in the performance arts is at least in part mediated by performances because certain qualities of those works—relevant to their proper appreciation as the particular works they are—are only realizable, and thereby made apparent to receivers, in performances.Philosophical discussion of the performing arts has largely been concerned with performances taking place in the performance arts as characterized above, and thus with performances of performed works. Indeed, most philosophical discussion of the performing arts has focused on performances of performed works of classical music, the assumption being that the model seen to apply to such examples—what we may term “the classical paradigm”—also applies, with very few exceptions, to performances in other musical genres (in particular, jazz and rock) and to performances in other performance media (in particular, theater and dance). In all of these cases, it has been widely assumed, performances are generally of works, and the work-performance relationship is to be understood on the model of the classical paradigm. Performances not obviously open to such an analysis—free improvisations in music or dance, for example—have been viewed either as limiting cases of the classical paradigm or as of only marginal interest for a philosophical treatment of the performing arts.IIOne among the many virtues of James Hamilton’s book is that it challenges the hegemony of the classical paradigm in the performing arts by questioning its applicability to theatrical performances. He argues instead for an “ingredients model” of the relationship between a literary script and a theatrical work. According to the ingredients model, the text produced by a playwright is merely one ingredient that theatrical performance companies take into account when they set out to create a performance.3 It is taken to be a consequence of this that “a [theatrical] performance is... never a performance of some other work nor is it ever a performance of a text or of anything initiated in a text.”4 The alternative idea that theatrical works are to be understood in terms of the classical paradigm is what Hamilton terms the “text-based” view of such works. But adherents of the views that he opposes to the ingredients model may deny that theatrical... (shrink)

Open peer commentary on the target article “Arguments Opposing the Radicalism of Radical Constructivism” by Gernot Saalmann. First paragraph: Gernot Saalmann presents in his paper an exposition of radical constructivism that throws together such diverse thinkers as von Glasersfeld, Maturana, Varela and Luhmann. He presents their views as something of a unified front, although actually only Glasersfeld consistently represents radical constructivism. In his exhibition and critique of radical constructivism Saalmann fluctuates between ontological, epistemological and neurophysiological arguments that have often little (...) bearing on the original ideas of radical constructivism. For example, his discussion on sensory coding (§16) is hardly relevant to the basic tenets of radical constructivism. “Sensory coding” entails that there is information in the environment that can be transmitted to the organism through senses; a model denied by radical constructivism (see e.g. Glasersfeld 1995a, pp. 115–116).

Tertium Organum, published in Russian in 1912, is the most interesting and important of these works. The title is explained as meaning that the book is about "the third canon of thought," namely the mystical, which has always existed, although for us moderns it appears as a third method after the deductive and inductive methods described by Aristotle and Bacon. The English translation by Nicholas Bessaraboff and Claude Bragdon was published by Manas Press in 1920, and again, revised, by Knopf (...) in 1922. The simplicity of the literary style, the short sentences and paragraphs, and the clarity with which subtle arguments are developed show the influence of the author's training as a journalist. In content Tertium Organum is a systematic treatise on epistemology. The first seven chapters are an objective survey of the physical world. The author considers that the most basic problem of physics is why space has just three dimensions, and he concludes that it is impossible to find any answer to this question in an objective study of the world of space and time. Consequently, taking as a clue Kant's thesis that space and time are forms of intuition, and inferring from this that "we bear within ourselves the conditions of our space," he approaches the problem subjectively. In the following chapters he endeavors to show how our mode of consciousness makes space three-dimensional, how other modes of consciousness would, and for other beings do, make it of fewer or more dimensions, and how these different spaces are related to each other. The next to last chapter is a collection of selections from mystical literature, with comments, and the concluding chapter considers the "cosmic consciousness" with has for its object a world of four dimensions. An appendix gives a table showing the space and time sense, psychology, logic, mathematics, forms of action, morals, forms of consciousness, forms of knowledge, and forms of science characteristic of, as well as the different beings characterized by, four "forms of the manifestation of consciousness.".

Quantum theory is a powerful framework for probabilistic modeling of cognition. Strong empirical evidence suggests the context- and order-dependent representation of human judgment and decision-making processes, which falls beyond the scope of classical Bayesian probability theories. However, considering behavior as the output of underlying neurobiological processes, a fundamental question remains unanswered: Is cognition a probabilistic process at all?

Critics of Rawls's A Theory of Justice frequently envision his original position as containing a human consciousness. Thus, the re- strictions Rawls introduces for this ‘individual’—the lack of particular circumstantial and personal information—is considered a potential problem. The very ways in which Rawls circumscribes the knowledge available in this position is thought to compromise the personhood of the individual there, and hence as well the conclusions reached (that is, Rawls’s two principles). This paper will argue that, on the contrary, the (...) lack of full personhood is a critical part of Rawls’s modeling strategy, and that Rawls borrowed this particular sense of modeling from eco- nomics. It is well known that Rawls worked to verse himself in economic theory, and it is difficult to overlook its use in Theory. It will be argued that it is through parallels with economic reasoning that Rawls’s original position model can be most fruitfully understood. (shrink)

Yarkoni argues that researchers making broad inferences often use impoverished statistical models that fail to include important sources of variation as random effects. We argue, however, that for many common study designs, random effects are inappropriate and insufficient to draw general inferences, as the source of variation is not random, but systematic.

One of the goals of computerized tutoring systems is to optimize the learning of facts. Over a hundred years of declarative memory research have identified two robust effects that can improve such systems: the spacing and the testing effect. By making optimal use of both and adjusting the system to the individual learner using cognitive models based on declarative memory theories, such systems consistently outperform traditional methods. This adjustment process is driven by a continuously updated estimate of the rate of (...) forgetting for each item and learner on the basis of the learner's accuracy and response time. In this study, we investigated to what extent these estimates of individual rates of forgetting are stable over time and across different materials. We demonstrate that they are stable over time but not across materials. Even though most theories of human declarative memory assume a single underlying rate of forgetting, we show that, in practice, it makes sense to assume different materials are forgotten at different rates. If a computerized, adaptive fact-learning system allowed different rates of forgetting for different materials, it could adapt to individual learners more readily. (shrink)

Aboriginal peoples are forever explaining themselves to non-Aboriginal people: telling their stories, explaining their beliefs and ceremonies, and introducing ideas that have never crossed the non-Aboriginal mind. Western knowledge operates from a linear, singular view; it views the world from order beneath chaos; it is very noun oriented; knowledge is about oneself in relation to everything else in a relativistic sense. Aboriginal knowledge has a very different “coming to know.” It is holistic and cyclical; it views the world from (...) chaos underneath order; its languages are process and action oriented. Knowledge is about participation in and with the natural world. (shrink)

The topics of modeling and information come together in at least two ways. Computational modeling and simulation play an increasingly important role in science, across disciplines from mathematics through physics to economics and political science. The philosophical questions at issue are questions as to what modeling and simulation are adding, altering, or amplifying in terms of scientific information. What changes with regard to information acquisition, theoretical development, or empirical confirmation with contemporary tools of computational modeling? In this sense the (...) title of this article is read in the following way: What kind of information is modeling information? What kind of information does modeling give us? (shrink)

Cancer biology features the ascription of normal functions to parts of cancers. At least some ascriptions of function in cancer biology track local normality of parts within the global abnormality of the aberration to which those parts belong. That is, cancer biologists identify as functions activities that, in some sense, parts of cancers are supposed to perform, despite cancers themselves having no purpose. The present paper provides a theory to accommodate these normal function ascriptions—I call it the Modeling Account (...) of Normal Function (MA). MA comprises two claims. First, normal functions are activities whose performance by the function-bearing part contributes to the self-maintenance of the whole system and, thereby, results in the continued presence of that part. Second, MA holds that models of system-level activities that are (partly) constitutive of self-maintenance are improved by including a representation of the relevant function-bearing part and by making reference to the activity/activities that part performs which contribute(s) to those system-level activities. I contrast MA with two other accounts that seek to explicate the ascription of normal functions in biology, namely, the organizational account and the selected effects account. Both struggle to extend to cancer biology. However, I offer ecumenical readings which allow them to recover some ascriptions of normal function to parts of cancers. So, though I contend that MA excels in this respect, the purpose of this paper is served if it provides materials for bridging the gap between cancer biology, philosophy of cancer, and the literature on function.

The modeling of black holes is an important desideratum for any quantum theory of gravity. Not only is a classical black hole metric sought, but also agreement with the laws of black hole thermodynamics. In this paper, we describe how these goals are achieved in string theory. We review black hole thermodynamics, and then explicate the general stringy derivation of classical spacetimes, the construction of a simple black hole solution, and the derivation of its entropy. With that in hand, we (...) address some important philosophical and conceptual questions: the confirmatory value of the derivation, the bearing of the model on recent discussions of the so-called ‘information paradox’, and the implications of the model for the nature of space.

Dualist and Reductionist theories of mind disagree about whether or not consciousness can be reduced to a state of or function of the brain. They assume, however, that the contents of consciousness are separate from the external physical world as-perceived. According to the present paper this assumption has no foundation either in everyday experience or in science. Drawing on evidence for perceptual projection in both interoceptive and exteroceptive sense modalities, the case is made that the physical world as-perceived is (...) a construct of perceptual processing and, therefore, part of the contents of consciousness. A finding which requires a Reflexive rather than a Dualist or Reductionist model of how consciousness relates to the brain and the physical world. The physical world as-perceived may, in turn be thought of as a biologically useful model of the world as described by physics. Redrawing the boundaries of consciousness to include the physical world as-perceived undermines the conventional separation of the 'mental' from the physical', and with it the very foundation of the Dualist-Reductionist debate. The alternative Reflexive model departs radically from current conventions, with consequences for many aspects of consciousness theory and research. Some of the consequences which bear on the internal consistency and intuitive plausibility of the model are explored, e.g. the causal sequence in perception, representationalism, a suggested resolution of the Realism versus Idealism debate, and the way manifest differences between physical events as-perceived and other conscious events are to be construed. In the present paper I wish to challenge some of our most deeply-rooted assumptions about what consciousness is, by re-examining how consciousness, the human brain, and the surrounding physical world relate to each other.

In empirical modeling, an important desiderata for deeming theoretical entities and processes as real is that they can be reproducible in a statistical sense. Current day crises regarding replicability in science intertwines with the question of how statistical methods link data to statistical and substantive theories and models. Different answers to this question have important methodological consequences for inference, which are intertwined with a contrast between the ontological commitments of the two types of models. The key to untangling them (...) is the realization that behind every substantive model there is a statistical model that pertains exclusively to the probabilistic assumptions imposed on the data. It is not that the methodology determines whether to be a realist about entities and processes in a substantive field. It is rather that the substantive and statistical models refer to different entities and processes, and therefore call for different criteria of adequacy. (shrink)

One challenge to creating realistic cognitive models of memory is the inability to account for the vast common–sense knowledge of human participants. Large computational knowledge bases such as WordNet and DBpedia may offer a solution to this problem but may pose other challenges. This paper explores some of these difficulties through a semantic network spreading activation model of the Deese–Roediger–McDermott false memory task. In three experiments, we show that these knowledge bases only capture a subset of human associations, while (...) irrelevant information introduces noise and makes efficient modeling difficult. We conclude that the contents of these knowledge bases must be augmented and, more important, that the algorithms must be refined and optimized, before large knowledge bases can be widely used for cognitive modeling.

This article examines how narratives mediate human interactions with environments to create a sense of place and identity. We begin with a review of the Greek poem Phaenomena to see how constellations brought a human dimension to the cosmos as well as a sense of predictability. A review of Jean-Paul Sartre’s Nausea illustrates the conception of indifferent space that erases the human presence, and how the imagination comes into play to fill the void. We examine how narratives work (...) to model aspects of environments and draw out meaning where before there was raw substance. Two seminal poems of Baudelaire then present a more subjective modeling of the environment. Pablo Neruda let his poetic vision be reflected in his three homes as protective playgrounds for his imagination. The article concludes that the models we examined are sheltering niches that help us feel at home in the world. As environments turn out to be more interactive, fragile, and complex than previously thought, our narratives also have to reflect on their impact on the sense of home they propose. (shrink)

The fields of machine learning (ML) and cognitive science have developed complementary approaches to computationally modeling human behavior. ML's primary concern is maximizing prediction accuracy; cognitive science's primary concern is explaining the underlying mechanisms. Cross-talk between these disciplines is limited, likely because the tasks and goals usually differ. The domain of e-learning and knowledge acquisition constitutes a fruitful intersection for the two fields’ methodologies to be integrated because accurately tracking learning and forgetting over time and predicting future performance based on (...) learning histories are central to developing effective, personalized learning tools. Here, we show how a state-of-the-art ML model can be enhanced by incorporating insights from a cognitive model of human memory. This was done by exploiting the predictive performance equation's (PPE) narrow but highly specialized domain knowledge with regard to the temporal dynamics of learning and forgetting. Specifically, the PPE was used to engineer timing-related input features for a gradient-boosted decision trees (GBDT) model. The resulting PPE-enhanced GBDT outperformed the default GBDT, especially under conditions in which limited data were available for training. Results suggest that integrating cognitive and ML models could be particularly productive if the available data are too high-dimensional to be explained by a cognitive model but not sufficiently large to effectively train a modern ML algorithm. Here, the cognitive model's insights pertaining to only one aspect of the data were enough to jump-start the ML model's ability to make predictions—a finding that holds promise for future explorations.

Many in philosophy understand truth in terms of precise semantic values, true propositions. Following Braun and Sider, I say that in this sense almost nothing we say is, literally, true. I take the stand that this account of truth nonetheless constitutes a vitally useful idealization in understanding many features of the structure of language. The Fregean problem discussed by Braun and Sider concerns issues about application of language to the world. In understanding these issues I propose an alternative modeling (...) tool summarized in the idea that inaccuracy of statements can be accommodated by their imprecision. This yields a pragmatist account of truth, but one not subject to the usual counterexamples. The account can also be viewed as an elaborated error theory. The paper addresses some prima facie objections and concludes with implications for how we address certain problems in philosophy. (shrink)

Teaching in higher education is critical and fraught with potential vicissitudes, which necessitates the presence of efficient professors armed with positive attributes to perform effectively. Although it is generally accepted that emotion regulation has numerous benefits for language teachers, in particular university professors, little is known about how it interacts with two other important constructs, i.e., self-efficacy and L2 grit. Furthermore, the effect of ER on L2 teacher grit has not been sufficiently investigated. To fill this gap, the current study (...) was to test a structural model of English as a Foreign Language university professors’ ER, self-efficacy, and L2 grit. The participants were 356 Iranian EFL university professors who completed the Language Teacher Emotion Regulation Inventory, the Teacher Sense of Efficacy Scale, and the L2-Teacher Grit Scale. The results of Structural Equation Modeling revealed that ER and self-efficacy were strong predictors of L2 grit. Moreover, the significant role of self-efficacy on ER was discovered. The implications of this study may foster effective teaching in higher education, particularly during the COVID-19 pandemic and its impacts on education. (shrink)

Next I turn (3) to the question whether relations can be reduced, bringing to bear considerations from the philosophy of physics as well as metaphysics. (...) Finally, (3) I consider in what sense relations have order, and whether to make sense of this we are required to conceive of relations as having direction or argument positions. (shrink)

Computer simulation modeling is an important part of contemporary scientific practice but has not yet received much attention from philosophers. The present project helps to fill this lacuna in the philosophical literature by addressing three questions that arise in the context of computer simulation of Earth's climate. Computer simulation experimentation commonly is viewed as a suspect methodology, in contrast to the trusted mainstay of material experimentation. Are the results of computer simulation experiments somehow deeply problematic in ways that the results (...) of material experiments are not? I argue against categorical skepticism toward the results of computer simulation experiments by revealing important parallels in the epistemologies of material and computer simulation experimentation. It has often been remarked that simple computer simulation models---but not complex ones---contribute substantially to our understanding of the atmosphere and climate system. Is this view of the relative contributions of simple and complex models tenable? I show that both simple and complex climate models can promote scientific understanding and argue that the apparent contribution of simple models depends upon whether a causal or deductive account of scientific understanding is adopted. When two incompatible scientific theories are under consideration, they typically are viewed as competitors, and we seek evidence that refutes at least one of the theories. In the study of climate change, however, logically incompatible computer simulation models are accepted as complementary resources for investigating future climate. How can we make sense of this use of incompatible models? I show that a collection of incompatible climate models persists in part because of difficulties faced in evaluating and comparing climate models. I then discuss the rationale for using these incompatible models together and argue that this climate model pluralism has both competitive and integrative components. (shrink)

This paper explores a semiotic notion of body as starting point for bridging biosemiotic with social semiotic theory. The cornerstone of the argument is that the social semiotic criticism of the classic view of meaning as double articulation can support the criticism of language-centrism that lies at the foundation of biosemiotics. Besides the pragmatic epistemological advantages implicit in a theoretical synthesis, I argue that this brings a semiotic contribution to philosophy of mind broadly. Also, it contributes to overcoming the polemic (...) in linguistics between, loosely put, cognitive universalism and cultural relativism. This possibility is revealed by the recent convergence of various semiotic theories towards a criticism of the classic notion of meaning as double articulation. In biosemiotics, the interest to explicate meaning as multiply articulated stems from the construal of Umwelt as relying on the variety of sense perception channels and semiotic systems that a species has at its disposal. Recently, social semiotics developed an unexplored interest for embodiment by starting from the other end, namely the consideration of the modal heterogeneity of meaning. To bridge these notions, I employ the cognitive semantic notion of embodiment and Mittelberg’s cognitive semiotic notion of exbodiment. In light of these, I explore the possible intricacies between the biosemiotic notion of primary modeling system and concepts referring to preconceptual structures for knowledge organization stemming from cognitive linguistics. Further, Mittelberg’s concept of exbodiment allows for a construal of meaning articulation as mediation between the exbodying and embodying directions of mind. (shrink)

Palaeontology developed as a field dependent upon comparison. Not only did reconstructing the fragmentary records of fossil organisms and placing them within taxonomic systems and evolutionary lineages require detailed anatomical comparisons with living and fossil animals, but the field also required thinking in terms of behavioural, biological and ecological analogies with modern organisms to understand how prehistoric animals lived and behaved. Yet palaeontological material often worked against making easy linkages, bringing a sense of mystery and doubt. This paper will (...) look at an animal whose study exemplified these problems: the Chalicothere. Increasingly recognized as a specific type from finds across North America and Eurasia from the early nineteenth century onwards, these prehistoric mammals showed short back legs terminating in pawed feet, long front limbs ending in sharp claws, a long flexible neck, and herbivorous grinding teeth. The Chalicothere became a significant organism within palaeontological studies, as the unexpected mix of characters made it a textbook example against the Cuvierian notion of “correlation of parts,” while explaining how the animal moved, fed and behaved became puzzling. However, rather than prevent comparisons, these actually led to comparative analogies becoming flexible and varied, with different forms of comparison being made with varying methods and degrees of confidence, and with the anatomy, movement and behaviour of giraffes, bears, horses, anteaters, primates and other organisms all serving at various points as potential models for different aspects of the animal. This paper will examine some of the attempts to reconstruct and define the Chalicotheres across a long timescale, using this to show how multiple comparisons and analogies could be deployed in a reconstructive and evolutionary science like palaeontology, and illustrate some of the limits and tensions in comparative methods, as they were used to reconstruct organisms which were thought to be incomparable to any modern animal.

The parameters governing our behavior are in constant flux, and capturing these dynamics in cognitive models remains a challenge. We demonstrate how a mapping between ACT‐R's model of declarative memory and the linear ballistic accumulator enables efficient estimation of memory parameters from data. The resulting estimates provide a cognitively meaningful explanation for observed differences in behavior over time and between individuals.

The parameters governing our behavior are in constant flux. Accurately capturing these dynamics in cognitive models poses a challenge to modelers. Here, we demonstrate a mapping of ACT-R's declarative memory onto the linear ballistic accumulator (LBA), a mathematical model describing a competition between evidence accumulation processes. We show that this mapping provides a method for inferring individual ACT-R parameters without requiring the modeler to build and fit an entire ACT-R model. Existing parameter estimation methods for the LBA can be used, (...) instead of the computationally expensive parameter sweeps that are traditionally done. We conduct a parameter recovery study to confirm that the LBA can recover ACT-R parameters from simulated data. Then, as a proof of concept, we use the LBA to estimate ACT-R parameters from an empirical dataset. The resulting parameter estimates provide a cognitively meaningful explanation for observed differences in behavior over time and between individuals. In addition, we find that the mapping between ACT-R and LBA lends a more concrete interpretation to ACT-R's latency factor parameter, namely as a measure of response caution. This work contributes to a growing movement towards integrating formal modeling approaches in cognitive science. (shrink)

The idea that cultural evolution exhibits variation, competition, and inheritance and therefore can be studied by adjusting the Darwinian theory of evolution by natural selection is an attractive one. It has been argued by a number of authors (e.g., Campbell 1960; Monod 1970; Dawkins 1976; Cavalli-Sforza and Feldman 1981; Boyd and Richerson 1985; Durham 1991; Aunger 2002; Mesoudi et al. 2004) and pursued in a variety of ways, some (Dawkins and memeticists) staying close to the Darwinian model, others (e.g., Boyd, (...) Richerson, and their collaborators) being more innovative. We agree that there are relevant analogies between biological and cultural evolution and, in particular, that cultural items do exhibit variation, competition, and cumulative modification. On the other hand, we believe that a proper understanding of the mechanisms of cultural propagation drawing on the work of cognitive and social scientists (see Sperber and Hirschfeld 1999 for a review) contradicts the idea that culture exhibits inheritance in the strict sense needed for the theory of evolution by natural selection to apply straightforwardly to it. If so, it will take more than adjusting the Darwinian model to be faithful to the Darwinian inspiration. (shrink)

Many in philosophy understand truth in terms of precise semantic values, true propositions. Following Braun and Sider, I say that in this sense almost nothing we say is, literally, true. I take the stand that this account of truth nonetheless constitutes a vitally useful idealization in understanding many features of the structure of language. The Fregean problem discussed by Braun and Sider concerns issues about application of language to the world. In understanding these issues I propose an alternative modeling (...) tool summarized in the idea that inaccuracy of statements can be accommodated by their imprecision. This yields a pragmatist account of truth, but one not subject to the usual counterexamples. The account can also be viewed as an elaborated error theory. The paper addresses some prima facie objections and concludes with implications for how we address certain problems in philosophy. (shrink)

Western culture, which influenced the whole world, came from Europe. But its roots are not there. They are in Athens and Jerusalem. European culture takes its bearing from references that are not in Europe: Europe is eccentric.What makes the West unique? What is the driving force behind its culture? Remi Brague takes up these questions in Eccentric Culture. This is not another dictionary of European culture, nor a measure of the contributions of a particular individual, religion, or national tradition. (...) The author's interest is especially, with regard to the transmission of that culture, to articulate the dynamic tension that has propelled Europe and more generally the West toward civilization. It is this mainspring of European culture, this founding principle, that Brague calls Roman.Yet the author's intent is not to write a history of Europe, and less yet to defend the historical reality of the Roman Empire. Brague rather isolates and generalizes one aspect of that history or, one might say, cultural myth, of ancient Rome. The Roman attitude senses its own incompleteness and recognizes the call to borrow from what went before it.Historically, it has led the West to borrow from the great traditions of Jerusalem and Athens: primarily the Jewish and Christian tradition, on the one hand, and the classical Greek tradition on the other. Nowhere does the author find this Roman character so strongly present as in the Christian and particularly Catholic attitude toward the incarnation.At once an appreciation of the richness and diversity of the sources and their fruit, Eccentric Culture points as well to the fragility of their nourishing principle. As such, Brague finds in it notonly a means of understanding the past, but of projecting a future in proposing to the West, and to Europe in particular, a model relationship of what is proper to it.An international bestseller, this work has been or is presently being translated into thirteen languages.

Professionalism, like common sense, remains a timeless ingredient in the ethically successful practice of medicine in the twenty-first century. Professional ideals are particularly relevant in times of economic and social upheaval, medicolegal crises, provider shortages, and global threats to the public health. The American Board of Internal Medicine specifies professionalism as “constituting those attitudes and behaviors that serve to maintain patient interest above physician self-interest.” Because of its transcendent nature, professionalism, like ethics, is also considered “a structurally stabilizing, morally (...) protective force in society.” Professions enjoy tremendous deference and autonomy in exchange for three unwritten but prerequisite promises: expert knowledge, self-regulation, and a fiduciary responsibility to place the needs of the client ahead of self-interest. Many educators suggest that professionalism includes additional characteristics such as honesty, altruism, temperance, commitment, integrity, and suspension of self-interest. However, there are large gaps in providing more user-friendly and operational models of professionalism to learners and evaluators at all levels of the academic hierarchy. (shrink)

The Enzymatic control reactions model was presented within the scope of fractional calculus. In order to accommodate the usual initial conditions, the fractional derivative used is in Caputo sense. The methodologies of the three analytical methods were used to derive approximate solution of the fractional nonlinear system of differential equations. Two methods use integral operator and the other one uses just an integral. Numerical results obtained exhibit biological behavior of real world problem.

Knowledge requires truth, and truth, we suppose, involves unflawed representation. Science does not provide knowledge in this sense but rather provides models, representations that are limited in their accuracy, precision, or, most often, both. Truth as we usually think of it is an idealization, one that serves wonderfully in most ordinary applications, but one that can terribly mislead for certain issues in philosophy. This article sketches how this happens for five important issues, thereby showing how philosophical method must take (...) into account the idealized nature of our familiar conception of truth.

The functioning of a subject in a changing environment is most effective from the point of view of survival if the subject can form, maintain and use internal representations of the external world for decision-making. These representations are also called reflection in a broad sense. Using it, one can win in reflexive games since an internal representation of the enemy allows predicting their future moves. The goal is to assess the reflexive potential of heuristic model objects – artificial neural (...) networks – in the reflexive games “Even-Odd” (or “Matching pennies”) and “Rock-Paper-Scissors”. We used homogeneous fully connected neural networks of small sizes (from 8 to 45 neurons). Games were played between neural networks with different configurations and parameters (size, step size for modifying weight coefficients). A set of reflexivity criteria is presented, corresponding to different levels of consideration: neuronal, behavioral, formal. The transitivity of formal success in the game is shown. The most successful configurations, however, may not meet other criteria of reflexivity. We hypothesize that the best compliance with the criteria and, as a consequence, universal success in reflection tasks is achievable for heterogeneous configurations with a structure in which the formation of hierarchical systems of attractors is possible.

In many cases, rivers, mountains, forests, and other so-called natural entities have value for us because they contribute to our well-being. According to the standard model of such value, they have instrumental or “service” value for us on account of their causal powers. That model tends, however, to come up short when applied to cases when nature contributes to our well-being by virtue of the religious, political, historical, personal, or mythic meanings it bears. To make sense of such cases, (...) a new model of nature’s value is needed, one that registers the fact that nature can have constitutive value for us on account of the role it plays in certain meaningful wholes, such as a person’s sense of who he or she is.

A person's cognitive map, or knowledge of large‐scale space, is built up from observations gathered as he travels through the environment. It acts as a problem solver to find routes and relative positions, as well as describing the current location. The TOUR model captures the multiple representations that make up the cognitive map, the problem‐solving strategies it uses, and the mechanisms for assimilating new information. The representations have rich collections of states of partial knowledge, which support many of the performance (...) characteristics of common‐sense knowledge. (shrink)

Although Charles S. Peirce, strictly speaking, never formulated a ‘full-blown’ normative theory—a single over-all architectonic system—we believe that there lies within his work a valuable sketch of the ideal for feeling, action, and thought, and how this ideal should be followed, and in connection to this, Peirce offered a model for rational behaviour, including self-control. In the following essay we will try, modestly, to draw a rough outline of this sketch. Firstly, we will focus on the three normative sciences, their (...) relationship and their task of finding out how feeling, action and thought ought to be controlled. Then, we will take a look at the sign-universe. The very universe is a sign-universe and within this evolutionary universe feeling, matter and thought incessantly melt together into ‘concrete reasonableness’; according to Peirce, rendering the world more reasonable. This is the Summum Bonum that man can and indeed should pursue. Hence it makes absolutely no sense to speak of the three normative sciences out of this metaphysical or cosmological context. Finally, we will try to see in what way rationality can be said to fall within the spheres of self-control, bearing in mind that self-control is directly related to conditional purpose. (shrink)

Amidst growing global endorsements of new biomedical HIV prevention strategies, ARV‐based pre‐exposure prophylaxis (ARV PrEP) has garnered considerable attention as a potentially promising prevention strategy. Though it may offer more effective protection for certain at‐risk groups than conventional prevention strategies (such as sexual partner reduction, condom use, and prevention of mother‐to‐child transmission), PrEP is more costly. PrEP requires more ongoing contact between individuals and providers, and a level of surveillance from the health system that is not necessary with other preventive (...) measures. In this sense, it represents a new bio‐technology for HIV prevention that poses particular challenges for worldwide implementation, given developing countries’ struggling health systems and incomplete HIV treatment programs. Since the emergence of PrEP has stimulated ethical discussions premised on incomplete knowledge of efficacy and implementation, this paper explores the ethical parameters of a likely scenario for PrEP usage in a single, resource‐poor country. We first develop a plausible model for PrEP deployment and utilization based on current PrEP research, while carefully considering the reigning institutional values of feasibility and effectiveness in global health approaches. Drawing on ethnographic research of HIV treatment and prevention approaches in Lesotho, we address ethical questions arising from this scenario of PrEP delivery. Lesotho presents a compelling and emblematic case study of PrEP's potential successes and pitfalls in a developing country, given the country's high HIV prevalence, struggles to achieve universal access to HIV treatment regimes, continued existence of stigma around the epidemic, and difficulties in addressing persistent social inequalities that fuel infections.

One challenge to creating realistic cognitive models of memory is the inability to account for the vast common–sense knowledge of human participants. Large computational knowledge bases such as WordNet and DBpedia may offer a solution to this problem but may pose other challenges. This paper explores some of these difficulties through a semantic network spreading activation model of the Deese–Roediger–McDermott false memory task. In three experiments, we show that these knowledge bases only capture a subset of human associations, while (...) irrelevant information introduces noise and makes efficient modeling difficult. We conclude that the contents of these knowledge bases must be augmented and, more important, that the algorithms must be refined and optimized, before large knowledge bases can be widely used for cognitive modeling.

This is the first major textbook to offer a truly comprehensive review of cognitive science in its fullest sense. Ranging across artificial intelligence models and cognitive psychology through to recent discursive and cultural theories Rom Harre offers a breathtakingly original yet accessible integration of the field. At its core this textbook addresses the question "is psychology a science?" with a clear account of scientific method and explanation and their bearing on psychological research. A pivotal figure in psychology and (...) philosophy for many decades Rom Harre has turned his unmatched breadth of reference and insight for students at all levels. Whether describing, language, categorization, memory, the brain or connectionism the book always links our intuitions about beliefs, desires and their social context to the latest accounts of their place in computational and biological models. Fluently written and well structured, this an ideal text for students. The book is divided into four basic modules, with three lectures in each; the reader is guided with helpful learning points, study and essay questions and key readings for each chapter. (shrink)
