Coherence and correspondence are classical contenders as theories of truth. In this paper we examine them instead as interacting factors in the dynamics of belief across epistemic networks. We construct an agent-based model of network contact in which agents are characterized not in terms of single beliefs but in terms of internal belief suites. Individuals update elements of their belief suites on input from other agents in order both to maximize internal belief coherence and to incorporate ‘trickled in’ elements of (...) truth as correspondence. Results, though often intuitive, prove more complex than in simpler models (Hegselmann & Krause 2002, 2006; Grim, Singer, Reade & Fisher 2015). The optimistic finding is that pressures toward internal coherence can exploit and expand on small elements of truth as correspondence is introduced into epistemic networks. Less optimistic results show that pressures for coherence can also work directly against the incorporation of truth, particularly when coherence is established first and new data is introduced later.

Conscious experiences are characterized by mental qualities, such as those involved in seeing red, feeling pain, or smelling cinnamon. The standard framework for modeling mental qualities represents them via points in geometrical spaces, where distances between points inversely correspond to degrees of phenomenal similarity. This paper argues that the standard framework is structurally inadequate and develops a new framework that is more powerful and flexible. The core problem for the standard framework is that it cannot capture precision structure: for example, (...) consider the phenomenal contrast between seeing an object as crimson in foveal vision versus merely as red in peripheral vision. The solution I favor is to model mental qualities using regions, rather than points. I explain how this seemingly simple formal innovation not only provides a natural way of modeling precision, but also yields a variety of further theoretical fruits: it enables us to formulate novel hypotheses about the space and structures of mental qualities, formally differentiate two dimensions of phenomenal similarity, generate a quantitative model of the phenomenal sorites, and define a measure of discriminatory grain. A noteworthy consequence is that the structure of the mental qualities of conscious experiences is fundamentally different from the structure of the perceptible qualities of external objects.

What is it to interpret the outputs of an opaque machine learning model? One approach is to develop interpretable machine learning techniques. These techniques aim to show how machine learning models function by providing either model-centric local or global explanations, which can be based on mechanistic interpretations (revealing the inner working mechanisms of models) or non-mechanistic approximations (showing input feature–output data relationships). In this paper, we draw on social philosophy to argue that interpreting machine learning outputs in certain normatively salient (...) domains could require appealing to a third type of explanation that we call “socio-structural” explanation. The relevance of this explanation type is motivated by the fact that machine learning models are not isolated entities but are embedded within and shaped by social structures. Socio-structural explanations aim to illustrate how social structures contribute to and partially explain the outputs of machine learning models. We demonstrate the importance of socio-structural explanations by examining a racially biased healthcare allocation algorithm. Our proposal highlights the need for transparency beyond model interpretability: understanding the outputs of machine learning systems could require a broader analysis that extends beyond the understanding of the machine learning model itself.

Central to Spinoza’s ethical theory is a model of human nature: the model of the free man. In this paper I argue that the idea of the free man is an inadequate idea when this is understood as the idea of a perfectly free finite thing. But when properly understood--that is, when the idea of the free man is understood as the idea of the perfection of our nature and power--the idea of the free man is a way of conceiving (...) God and is, as such, an adequate idea. (shrink)

The Incarnation, traditionally understood as the metaphysical union between true divinity and true humanity in the one person of Jesus Christ, is one of the central doctrines for Christians over the centuries. Nevertheless, many scholars have objected that the Scriptural account of the Incarnation is incoherent. Being divine seems to entail being omniscient, omnipotent and omnipresent, but the New Testament portrays Jesus as having human properties such as being apparently limited in knowledge, power, and presence. It seems logically impossible that (...) any single individual could possess such mutually exclusive sets of properties, and this leads to scepticism concerning the occurrence of the Incarnation in history. A Kryptic Model of the Incarnation aims to provide a critical reflection of various attempts to answer these challenges and to offer a compelling response integrating aspects from analytic philosophy of religion, systematic theology, and historical-critical studies. Loke develops a new Kryptic model of the Incarnation, drawing from the Greek word Krypsis meaning ’hiding’, and proposing that in a certain sense Christ’s supernatural properties were concealed during the Incarnation.

The collapse models of arithmetic are inconsistent, nontrivial models obtained from ℕ and set out in the Logic of Paradox (LP). They are given a general treatment by Priest (Priest, 2000). Finite collapse models are decidable, and thus axiomatizable, because finite. LP, however, is ill-suited to normal axiomatic reasoning, as it invalidates Modus Ponens, and almost all other usual conditional inferences. I set out a logic, A3, first given by Avron (Avron, 1991), and give a first order axiom system for (...) the finite collapse models. I present some standard arithmetical axioms in addition to a cyclic axiom and prove that these axioms are sound and complete for the cyclic models, reporting a similar result for the heap models. The state of the situation for the each of the kinds of infinite collapse model is, however, left an open question. (shrink)

Smith (Philosophy and Phenomenological Research, 55, 1995, 109) and Manne (Philosophical Studies, 167, 2014, 89), both following Williams (Making sense of humanity, Cambridge University Press, Cambridge, 1995), have developed advice‐based models of practical reasons. However, advice is not an apt model for reasons. The case for such pessimism is made by examining the positions of Smith and Manne first as attempts to explain the nature of reasons, then as suggestions for reforming our conception of reasons for action. The explanatory projects (...) fail: both views either omit or distort ordinary reasons. The reforming project fails because insufficient reason is provided for thinking that the significant extent of revision offered by these models is worth it. Overall, the advice‐based approach to understanding reasons fails because advising is a social practice to aid with decisions, whereas reasons are considerations that favour action regardless of whether these considerations are inputs to or outputs from such a practice.

This is a commentary for a special issue on predictive processing and rational constructivist models of development. Mainly I use the opportunity to ask a bunch of questions about what these theoretical frameworks show us (and what they do not) and mostly where the open questions still are. To get meta for a moment, I thought these questions were the best way to maximize the value of my commentary: They have the highest probability of leading to the most uncertainty reduction (...) for our field in the long term. Please read in that spirit. (shrink)

This study analyses the predictions of the General Theory of Relativity (GTR) against a slightly modified version of the standard central mass solution (Schwarzschild solution). It is applied to central gravity in the solar system, the Pioneer spacecraft anomalies (which GTR fails to predict correctly), and planetary orbit distances and times, etc (where GTR is thought consistent.) -/- The modified gravity equation was motivated by a theory originally called ‘TFP’ (Time Flow Physics, 2004). This is now replaced by the ‘Geometric (...) Model’, 2014 [20], which retains the same theory of gravity. This analysis is offered partially as supporting detail for the claim in [20] that the theory is realistic in the solar system and explains the Pioneer anomalies. The overall conclusion is that the model can claim to explain the Pioneer anomalies, contingent on the analysis being independently verified and duplicated of course. -/- However the interest lies beyond testing this theory. To start with, it gives us a realistic scale on which gravity might vary from the accepted theory, remain consistent with most solar-scale astronomical observations. It is found here that the modified gravity equation would appear consistent with GTR for most phenomena, but it would retard the Pioneer spacecraft by about the observed amount (15 seconds or so at time). Hence it is a possible explanation of this anomaly, which as far as I know remains unexplained now for 20 years. -/- It also shows what many philosophers of science have emphasized: the pivotal role of counterfactual reasoning. By putting forward an exact alternative solution, and working through the full explanation, we discover a surprising ‘counterfactual paradox’: the modified theory slightly weakens GTR gravity – and yet the effect is to slow down the Pioneer trajectory, making it appear as if gravity is stronger than GTR. The inference that “there must be some tiny extra force…” (Musser, 1998 [1]) is wrong: there is a second option: “…or there may be a slightly weaker form of gravity than GTR.” . (shrink)

The study of academic misconduct in higher education spans generations. Reducing the problem among college students remains a top priority among university stakeholders. There are several theoretical explanations for why students cheat, including the institutional climate around academic integrity, motivational achievement goal structures, peer norms, and moral attitudes. These models have rarely been examined in concert to ascertain a more complete picture of the nuances of academic dishonesty. Understanding the interplay between these theoretical explanation(s) would be an important step in (...) developing programming aimed at reducing cheating in higher education. The purpose of this study was toexamine the role of these theoretical explanations in predicting academic cheating as well as a combined model with all constructs. Using a sample of 2,329 undergraduates, we found that all five models were significantly associated with self-reported cheating, but in unique ways depending on the model. Implications for theory and practice are discussed. (shrink)

In spite of the wide variety of approaches to ethics training it is still debatable which approach has the highest potential to enhance professionals’ integrity. The current effort assesses a novel curriculum that focuses on metacognitive reasoning strategies researchers use when making sense of day-to-day professional practices that have ethical implications. The evaluated trainings effectiveness was assessed by examining five key sensemaking processes, such as framing, emotion regulation, forecasting, self-reflection, and information integration that experts and novices apply in ethical decision-making. (...) Mental models of trained and untrained graduate students, as well as faculty, working in the field of physical sciences were compared using a think-aloud protocol 6 months following the ethics training. Evaluation and comparison of the mental models of participants provided further validation evidence for sensemaking training. Specifically, it was found that trained students applied metacognitive reasoning strategies learned during training in their ethical decision-making that resulted in complex mental models focused on the objective assessment of the situation. Mental models of faculty and untrained students were externally-driven with a heavy focus on autobiographical processes. The study shows that sensemaking training has a potential to induce shifts in researchers’ mental models by making them more cognitively complex via the use of metacognitive reasoning strategies. Furthermore, field experts may benefit from sensemaking training to improve their ethical decision-making framework in highly complex, novel, and ambiguous situations. (shrink)

Moral psychologists have recently turned their attention to a phenomenon they call 'moral dumbfounding'. Moral dumbfounding occurs when someone confidently pronounces a moral judgment, then finds that he or she has little or nothing to say in defense of it. This paper addresses recent attempts by Jonathan Haidt and Marc Hauser to make sense of moral dumbfounding in terms of their respective theories of moral judgment; Haidt in terms of a 'social intuitionist' model of moral judgment, and Hauser in terms (...) of his 'Rawlsian creature' model of moral judgment. I show that Haidt and Hauser assume that moral dumbfounding is to be explained in terms of features of a.) moral judgment that are b.) construed in terms of the intrinsic features of individuals. By contrast, I hypothesize that moral dumbfounding is to be explained in terms of moral reasoning, more specifically in terms of the social dynamics of such reasoning. Finally, I argue that this hypothesis points towards an externalistic account of both moral reasoning and moral judgment. (shrink)

What does it mean to say that a scientific theory is unified? Prominent attempts by John Watkins, Philip Kitcher, and Margaret Morrison to answer this question face serious difficulties, and many analysts of science remain pessimistic about the possibility of ever rendering precise or explaining what theoretical unity consists in. This paper gives grounds for optimism, offering a novel account of the concept of unification. This account is tested against a detailed study of the standard model in contemporary high-energy physics, (...) a theory for which a high degree of unity has repeatedly been claimed. (shrink)

A significant increase in the probability of an action resulting from observing that action performed by another agent cannot, on its own, provide persuasive evidence of imitation. Simple models of social influence based on two-person sequential games suggest that both imitation and pseudo-imitation can be explained by a process more fundamental than priming, namely, subjective utility maximization.

ObjectiveTo present the ethical issues, moral arguments, and reasons found in the ethical literature on organoid models.DesignIn this systematic review of reasons in ethical literature, we selected sources based on predefined criteria: The publication mentions moral reasons or arguments directly relating to the creation and/or use of organoid models in biomedical research; These moral reasons and arguments are significantly addressed, not as mere passing mentions, or comprise a large portion of the body of work; The publication is peer-reviewed and published (...) in an academic article, book, national-level report, working paper, or Ph.D. thesis; The publications collected are in English.AnalysisEach article was read in-depth for identifiable moral reasons, arguments, and concerns. These were then inductively classified and synthesized to create broader categories of reasons, and eventually an overarching conceptual scheme was created.ResultsA total of twenty-three sources were included and analyzed out of an initial 266 collected sources. Five themes of ethical issues and arguments were found: Animal Experimentation; Clinical Applications and Experiments; Commercialization and Consent; Organoid Ontology and Moral Status; and Research Ethics and Research Integrity. These themes are then further broken down into sub-themes and topics. Given the extensive nature of the topics found, we will focus on describing the topics that comprised of more in-depth reasons and arguments rather than few, passing mentions or concerns.ConclusionsThe ethics of organoids requires further deliberation in multiple areas, as much of the discussions are not presented as in-depth arguments. Such sentiments are also echoed throughout the organoid ethics literature. (shrink)

Aesthetics, in many ways, is at the center of Adorno's philosophical enterprise. Politics and social critique are, in turn, very much at the fore in his aesthetics. His art criticism is thereby bound up with social and political critique. That much is of course a truism about Adorno. In this essay, I shall suggest that Adorno's social criticism (in one of its main manifestations) is related to his art criticism in another interesting way as well. Specifically, their form is similar. (...) The object of critical analysis, whether an artwork or other social phenomenon, is objectionable not simply because it promotes or fosters problematic things downstream – authoritarianism, anti‐Semitism, and the like – as cause to effect. Rather, it is objectionable because it contains, often in a way difficult immediately to detect, such objectionable ideologies covertly embedded in it. Critique will thus be a hermeneutic endeavor seeking to expose these ideologies. While this critical‐interpretive model is of course more familiar in the aesthetic sphere, Adorno extends it to unmasking a wider range of social phenomena. (shrink)

The standard model of cosmology is acclaimed in physics as accurate, robust, well-tested, our best scientific theory of the cosmos, but it has had serious anomalies for a while, including the Hubble tension, anomalous galaxies, and the completely unexplained nature of dark energy and dark matter. And lurking behind it all is the lack of a unified theory: General Relativity (GR) and quantum mechanics (QM) are inconsistent. Now startling new observations by the James Webb Space Telescope (JWST) in 2022 of (...) the early universe present the strongest challenge yet to the standard model, and whispers have started that this shows there is something wrong with the fundamental theory, General Relativity itself. This would be a crisis for cosmology. But haven’t they tested this theory already, and shown it is correct? How could it turn out wrong at this late stage? Here we compare the standard cosmology with an alternative fundamental theory, that has a strikingly different overall cosmological behavior: a simple cyclic expansion function. It is simple and deterministic. There are only two or three general parameters. The interesting result is that this alternative cosmology: (A) closely matches the expansion observed and modelled through the CDM standard model, now going back to red-shifts of 5-15; and (B) it also predicts unexpected early galaxy formation now being reported by the JWST. The point here is not to try to prove this alternative theory however, but rather show how it compares to the conventional cosmology. This show us clearly how weak the empirical evidence for the standard model really is against a counterfactual fundamental theory. Some results established in science are robust against theory change, but we find the standard cosmological model and the implications drawn from it are not robust at all. (shrink)

In this paper, we describe a model that learns semantic representations from the distributional statistics of language. This model, however, goes beyond the common bag‐of‐words paradigm, and infers semantic representations by taking into account the inherent sequential nature of linguistic data. The model we describe, which we refer to as a Hidden Markov Topics model, is a natural extension of the current state of the art in Bayesian bag‐of‐words models, that is, the Topics model of Griffiths, Steyvers, and Tenenbaum (2007), (...) preserving its strengths while extending its scope to incorporate more fine‐grained linguistic information.

How do teachers learn about what learners already know? How do learners aid teachers by providing them with information about their background knowledge and what they find confusing? We formalize this collaborative reasoning process using a hierarchical Bayesian model of pedagogy. We then evaluate this model in two online behavioral experiments (N = 312 adults). In Experiment 1, we show that teachers select examples that account for learners' background knowledge, and adjust their examples based on learners' feedback. In Experiment 2, (...) we show that learners strategically provide more feedback when teachers' examples deviate from their background knowledge. These findings provide a foundation for extending computational accounts of pedagogy to richer interactive settings. (shrink)

I show that the Pinkerton rule in conspiracy law is doctrinally and morally flawed. Unlike past critics of the rule, I propose a statutory fix that preserves and reforms it rather than abolishing it entirely. As I will show, this accommodates authors like Neil Katyal who have defended the rule as an important crime fighting tool while also fixing most of the traditional problems with it identified by critics like Wayne LaFave. Pinkerton is a vicarious liability rule that makes conspirators (...) criminally responsible for the foreseeable crimes of their coconspirators committed in furtherance of the conspiracy. It has two big problems: (1) Doctrinally, it breaks the logic of the many state criminal codes that are based on the Model Penal Code. (2) Ethically, it infringes the culpability constraint on the criminal law by imposing excessive punishments on defendants who did not even consciously suspect that their coconspirators would commit additional crimes that were not the object of the conspiracy. These problems are most acute in Texas, where Pinkerton can be combined with capital murder charges to produce automatic life without parole sentences. The Texas example is an extreme illustration of the problem of unintended consequences when state legislators tinker with the carefully drafted, interlocking provisions of a model code. The new statute I propose would put the penal code back in order and respect the culpability constraint. In the latter aspect, it is informed by leading work in philosophical ethics on blameworthiness and culpability. (shrink)

Threshold- and signal-detection-based models have dominated theorizing about recognition memory. Building upon these theoretical frameworks, we have argued for a dual-process model in which conscious recollection and familiarity contribute to memory performance. In the current paper we assessed several memory models by examining the effects of levels of processing and the number of presentations on recognition memory receiver operating characteristics . In general, when the ROCs were plotted in probability space they exhibited an inverted U shape; however, when they were (...) plotted inzspace they exhibited a U shape. An examination of the ROCs showed that the dual-process model could account for the observed ROCs, but that models based solely on either threshold or signal-detection processes failed to provide a sufficient account of the data. Furthermore, an examination of subjects' introspective reports using the remember/know procedure showed that subjects were aware of recollection and familiarity and were able to consistently report on their occurrence. The remember/know data were used to accurately predict the shapes of the ROCs, and estimates of recollection and familiarity derived from the ROC data mirrored the subjective reports of these processes.

Many skeptics throughout the centuries have accused the New Testament characterization of the incarnation as being incoherent. The reason is that it appears impossible that any person can exemplify human properties such as ignorance, fatigability, and spatial limitation, as the New Testament testifies of Jesus, while possessing divine properties such as omniscience, omnipotence, and omnipresence at the same time. This paper proposes a possible model which asserts that at the incarnation, the Logo's mind was divided into conscious and preconscious, and (...) the divine properties were transferred from the conscious into the preconscious, which became part A of Jesus' preconscious. Simultaneously, the conscious acquired newly created human properties, while a human preconscious which would become part B of Jesus' preconscious and a human body were also created. It is demonstrated that this model does not suffer from the problems that beset other models such as Apollinarianism, two-consciousness Christology, and ontological Kenoticism, and that based on this model the full attributes of divinity and humanity of Jesus as testified by the Scriptures could have simultaneously coexisted in one person without contradiction.

I next give a construction showing that the conditions Solovay (...) identified for his characterization of degrees of models of arbitrary completions of PA cannot be dropped (I showed that these conditions cannot be simplified in the paper.

Instead of using low-level neurophysiology mimicking and exploratory programming methods commonly used in the machine consciousness field, the hierarchical Operational Architectonics (OA) framework of brain and mind functioning proposes an alternative conceptual-theoretical framework as a new direction in the area of model-driven machine (robot) consciousness engineering. The unified brain-mind theoretical OA model explicitly captures (though in an informal way) the basic essence of brain functional architecture, which indeed constitutes a theory of consciousness. The OA describes the neurophysiological basis of the (...) phenomenal level of brain organization. In this context the problem of producing man-made “machine” consciousness and “artificial” thought is a matter of duplicating all levels of the operational architectonics hierarchy (with its inherent rules and mechanisms) found in the brain electromagnetic field. We hope that the conceptual-theoretical framework described in this paper will stimulate the interest of mathematicians and/or computer scientists to abstract and formalize principles of hierarchy of brain operations which are the building blocks for phenomenal consciousness and thought.

This study presents a new type of foundational model unifying quantum theory, relativity theory and gravitational physics, with a novel cosmology. It proposes a six-dimensional geometric manifold as the foundational ontology for our universe. The theoretical unification is simple and powerful, and there are a number of novel empirical predictions and theoretical reductions that are strikingly accurate. It subsequently addresses a variety of current anomalies in physics. It shows how incomplete modern physics is by giving an example of a theory (...) that is genuinely unified. In doing this, it radically alters the metaphysical interpretation of the nature of time, space and matter currently interpreted from modern physics. It also profoundly challenges materialist expectations about a naturalistic account our own existence. I contend here that there is sufficient evidence to support this theory as a leading paradigm for a unified foundational theory. (shrink)

Ferrari’s critique founders on two issues. Firstly, he does not always represent Toulmin’s view of mathematics and mathematical arguments accurately (indeed, he sometimes attributes to Toulmin positions Toulmin was actually attacking).

Linear mixed-effect models (LMMs) are being increasingly widely used in psychology to analyse multi-level research designs. This feature allows LMMs to address some of the problems identified by Speelman and McGann ( 2013 ) about the use of mean data, because they do not average across individual responses. However, recent guidelines for using LMM to analyse skewed reaction time (RT) data collected in many cognitive psychological studies recommend the application of non-linear transformations to satisfy assumptions of normality. Uncritical adoption of (...) this recommendation has important theoretical implications which can yield misleading conclusions. For example, Balota et al. ( 2013 ) showed that analyses of raw RT produced additive effects of word frequency and stimulus quality on word identification, which conflicted with the interactive effects observed in analyses of transformed RT. Generalized linear mixed-effect models (GLMM) provide a solution to this problem by satisfying normality assumptions without the need for transformation. This allows differences between individuals to be properly assessed, using the metric most appropriate to the researcher's theoretical context. We outline the major theoretical decisions involved in specifying a GLMM, and illustrate them by reanalysing Balota et al.'s datasets. We then consider the broader benefits of using GLMM to investigate individual differences. (shrink)

In a recent review published in Journal of Analytic Theology, James Arcadi offers a defence of the Two Consciousnesses Model against Loke’s criticisms previously published in this journal. Arcadi postulates that Christ could have one centre of the two ranges of consciousness and one centre of operation. I argue that Arcadi’s postulation preserves the unity of the person but is beset by another problem, namely that on Arcadi’s view the one centre of experiences of Christ would have experienced the unlimited (...) scope of awareness through his divine nature, which rule out the possibility that he experienced human limitations with regards to his scope of experiences.

One approach to validating simulation models is to formally compare model outputs with independent data. We consider such model validation from the point of view of Frequentist statistics. A range of estimates and tests of goodness of fit have been advanced. We review these approaches, and demonstrate that some of the tests suffer from difficulties in interpretation because they rely on the null hypothesisHypothesis that the model is similar to the observationsObservations. This reliance creates two unpleasant possibilities, namely, a model (...) could be spuriously validated when dataData are too few, or inappropriately rejected when data are too many. Finally, these tests do not allow a principled declaration of what a reasonable level of difference would be considering the purposes to which the model will be put. We consider equivalence tests, and demonstrate that they do not suffer from the previously identified shortcomings. We provide two case studies to illustrate the claims of the chapter. (shrink)

A number of increasingly sophisticated technologies are now being used to support complex decision-making in a range of contexts. This paper reports on work undertaken to provide decision support in the discretionary domain of sentencing by referring to a recently created Toulmin argument based model that involves the interplay and weighting of relevant rule-based and discretionary factors used in a decisional process. Judicial discretion, particularly in the sentencing phase, is one of the mainstays of justice systems that favour individualised justice. (...) The study discusses the modelling process in Victorian courts in Australia, where the handing down of an appropriate custodial or non-custodial sentence requires the consideration of many factors. Tools and techniques used to capture relevant expert knowledge and display it both as a paper model and as an online prototype application are discussed. (shrink)
