The increasing preponderance of opinion that some natural phenomena can be explained mathematically has inspired a search for a viable account of distinctively mathematical explanation. Among the desiderata for an adequate account is that it should solve the problem of directionality and the reversals of distinctively mathematical explanations should not count as members among the explanatory fold but any solution must also avoid the exclusion of genuine explanations. In what follows, I introduce and defend what I refer to as a (...) quasi-erotetic solution which provides a remedy to the problem in the form of an additional necessary condition on explanation.

Authored by an acclaimed teacher of quantum physics and philosophy, this textbook pays special attention to the aspects that many courses sweep under the carpet. Traditional courses in quantum mechanics teach students how to use the quantum formalism to make calculations. But even the best students - indeed, especially the best students - emerge rather confused about what, exactly, the theory says is going on, physically, in microscopic systems. This supplementary textbook is designed to help such students understand that they (...) are not alone in their confusions (luminaries such as Albert Einstein, Erwin Schroedinger, and John Stewart Bell having shared them), to sharpen their understanding of the most important difficulties associated with interpreting quantum theory in a realistic manner, and to introduce them to the most promising attempts to formulate the theory in a way that is physically clear and coherent. The text is accessible to students with at least one semester of prior exposure to quantum (or "modern") physics and includes over a hundred engaging end-of-chapter "Projects" that make the book suitable for either a traditional classroom or for self-study.

J. L. Schellenberg’s “problem of divine hiddenness” has generated much discussion. Swinburne has replied with his “responsibility argument,” according to which God allows some nonresistant nonbelief in order to foster the good of human responsibility, with some people tasked with leading others to belief in God. Schellenberg has supplied detailed replies to Swinburne. My goal is to provide a new formulation of the responsibility argument that defuses Schellenberg’s objections.

In this book, Travis DeCook explores the theological and political innovations found in early modern accounts of the Bible's origins. In the charged climate produced by the Reformation and humanist historicism, writers grappled with the tension between the Bible's divine and human aspects, and they produced innovative narratives regarding the agencies and processes through which the Bible came into existence and was transmitted. DeCook investigates how these accounts of Scripture's production were taken up beyond the expected boundaries of biblical (...) study, and were redeployed as the theological basis for wide-reaching arguments about the proper ordering of human life. DeCook provides a new, critical perspective on ideas regarding secularity, secularization, and modernity, challenging the dominant narratives regarding the Bible's role in these processes. He shows how these engagements with the Bible's origins prompt a rethinking of formulations of secularity and secularization in our own time. (shrink)

In this single-blind within-subject study, autonomic and EEG variables were compared during 10-min, order-balanced eyes-closed rest and Transcendental Meditation (TM) sessions. TM sessions were distinguished by (1) lower breath rates, (2) lower skin conductance levels, (3) higher respiratory sinus arrhythmia levels, and (4) higher alpha anterior-posterior and frontal EEG coherence. Alpha power was not significantly different between conditions. These results were seen in the first minute and were maintained throughout the 10-min sessions. TM practice appears to (1) lead to a (...) state fundamentally different than eyes-closed rest; (2) result in a cascade of events in the central and autonomic nervous systems, leading to a rapid change in state (within a minute) that was maintained throughout the TM session; and (3) be best distinguished from other conditions through autonomic and EEG alpha coherence patterns rather than alpha power. Two neural networks that may mediate these effects are suggested. The rapid shift in physiological functioning within the first minute might be mediated by a ''neural switch'' in prefrontal areas inhibiting activity in specific and nonspecific thalamocortical circuits. The resulting ''restfully alert'' state might be sustained by a basal ganglia-corticothalamic threshold regulation mechanism automatically maintaining lower levels of cortical excitability. (shrink)

Charles Travis presents a series of essays in which he has developed his distinctive view of the relation of thought to language. The key idea is "occasion-sensitivity": what it is for words to express a given concept is for them to be apt for contributing to any of many different conditions of correctness (notably truth conditions). Since words mean what they do by expressing a given concept, it follows that meaning does not determine truth conditions. This view ties thoughts (...) less tightly to the linguistic forms which express them than traditional views of the matter, and in two directions: a given linguistic form, meaning fixed, may express an indefinite variety of thoughts; one thought can be expressed in an indefinite number of syntactically and semantically distinct ways. Travis highlights the importance of this view for linguistic theory, and shows how it gives new form to a variety of traditional philosophical problems. (shrink)

Abstract On Schellenberg’s formulation of the problem of divine hiddenness, a loving God would ensure that anyone capable of having a relationship with Him, and not resisting it, would be granted sufficient evidence to make belief in God rationally indubitable. And He would do this by granting a powerful religious experience to every person at the moment he or she reaches the age of reason. Here I lay out a new reason why God might delay revelation of himself, justifiably allowing (...) for some nonresistant nonbelief.

We examine the prevalent use of the phrase “local realism” in the context of Bell’s Theorem and associated experiments, with a focus on the question: what exactly is the ‘realism’ in ‘local realism’ supposed to mean? Carefully surveying several possible meanings, we argue that all of them are flawed in one way or another as attempts to point out a second premise (in addition to locality) on which the Bell inequalities rest, and (hence) which might be rejected in the face (...) of empirical data violating the inequalities. We thus suggest that the phrase ‘local realism’ should be banned from future discussions of these issues, and urge physicists to revisit the foundational questions behind Bell’s Theorem. (shrink)

I consider how complex logical operations might self-assemble in a signalling-game context via composition of simpler underlying dispositions. On the one hand, agents may take advantage of pre-evolved dispositions; on the other hand, they may co-evolve dispositions as they simultaneously learn to combine them to display more complex behaviour. In either case, the evolution of complex logical operations can be more efficient than evolving such capacities from scratch. Showing how complex phenomena like these might evolve provides an additional path to (...) the possibility of evolving more or less rich notions of compositionality. This helps provide another facet of the evolutionary story of how sufficiently rich, human-level cognitive or linguistic capacities may arise from simpler precursors. 1Signalling and Self-assembly2Simple Unary Logic Games3Composing Unary Functions for Binary Inputs 3.1Utilizing pre-evolved dispositions3.2Co-evolving logical dispositions3.3Learning appropriate outputs3.4Taking account of the full state-space of unary games3.5Role-free composition4Discussion 4.1Efficacy and efficiency of learning complex dispositions4.2Other binary operations4.3To infinity and beyond5Conclusion.

I introduce an extension of the Lewis-Skyrms signaling game, analysed from a dynamical perspective via simple reinforcement learning. In Lewis’ (Convention, Blackwell, Oxford, 1969) conception of a signaling game, salience is offered as an explanation for how individuals may come to agree upon a linguistic convention. Skyrms (Signals: evolution, learning & information, Oxford University Press, Oxford, 2010a) offers a dynamic explanation of how signaling conventions might arise presupposing no salience whatsoever. The extension of the atomic signaling game examined here—which I (...) will refer to as a salience game—introduces a variable parameter into the atomic signaling game which allows for degrees of salience, thus filling in the continuum between Skyrms’ and Lewis’ models. The model does not presuppose any salience at the outset, but illustrates a process by which accidentally evolved salience is amplified, to the benefit of the players. It is shown that increasing degrees of salience allow populations to avoid sub-optimal pooling equilibria and to coordinate upon conventions more quickly. (shrink)

Multidisciplinary critiques of the notion of rape as an evolutionary adaptation.

This study compared professional and amateur classical musicians matched for age, gender, and education on reaction times during the Stroop color-word test, brainwaves during an auditory ERP task and during paired reaction-time tasks, responses on the Gibbs Sociomoral Reflection questionnaire, and self-reported frequencies of peak experiences. Professional musicians were characterized by: lower color-word interference effects , faster categorization of rare expected stimuli , and a trend for faster processing of rare unexpected stimuli , higher scores on the Sociomoral Reflection questionnaire, (...) and more frequent peak experiences during rest, tasks, and sleep. Both groups had high values on the Brain Integration Scale. These findings are interpreted in light of a Unified Theory of Performance, which posits that effectiveness in any area is influenced by one’s level of mind-brain development—emotional, cognitive, moral, ego and cortical development—with higher mind-brain development supporting greater effectiveness in any domain.

Multiple theories of problem-solving hypothesize that there are distinct qualitative phases exhibited during effective problem-solving. However, limited research has attempted to identify when transitions between phases occur. We integrate theory on collaborative problem-solving with dynamical systems theory suggesting that when a system is undergoing a phase transition it should exhibit a peak in entropy and that entropy levels should also relate to team performance. Communications from 40 teams that collaborated on a complex problem were coded for occurrence of problem-solving processes. (...) We applied a sliding window entropy technique to each team's communications and specified criteria for identifying data points that qualify as peaks and determining which peaks were robust. We used multilevel modeling, and provide a qualitative example, to evaluate whether phases exhibit distinct distributions of communication processes. We also tested whether there was a relationship between entropy values at transition points and CPS performance. We found that a proportion of entropy peaks was robust and that the relative occurrence of communication codes varied significantly across phases. Peaks in entropy thus corresponded to qualitative shifts in teams’ CPS communications, providing empirical evidence that teams exhibit phase transitions during CPS. Also, lower average levels of entropy at the phase transition points predicted better CPS performance. We specify future directions to improve understanding of phase transitions during CPS, and collaborative cognition, more broadly. (shrink)

The goal of this article is to evaluate the defensibility of wide-spread beliefs concerning the moral value of procreating. Very many of us are ‘pro-natal’ — that is, we have a positive moral view of making more people — but pro-natalism is under serious threat. In particular, I argue that combining several arguments in procreative ethics generates a powerful case for the Anti-Natal Pro-Adoption View, or the view that we are obligated not to procreate, but instead to satisfy any parenting (...) desires through adoption. Although this article ultimately serves as a defence against ANPA, it does so in a very limited way: while it is false that we are obligated to adopt-rather-than-procreate, I contend, this does not mean that we are off the moral hook altogether. Failing in our obligations is only one way to fail morality. Our procreative acts may yet be bad, dishonourable, selfish, and open to multiple other criticisms. And indeed, I'm afraid many of them are. (shrink)

It has historically been a crime in Canada to provide assistance to someone in ending their own life, however, this paradigm was inverted in 2015 when the Supreme Court of Canada ruled that restrictions on this practice, within certain defined parameters, violated the right to life, liberty, and security of the person. Subsequently, recent legal and policy decisions have highlighted the issue of how to balance the rights of individuals to access MAiD with the rights of care providers to exercise (...) conscience-based objections to participation in this process. We argue that there is significant harm and ethical hazard in disregarding individual and institutional rights to conscientious objection and since measures less coercive than the threat of regulatory or economic sanctions do exist, there should be no justification for such threats in Canada’s health care systems.

If God exists, why isn't His existence more apparent? In recent analytic philosophy this longstanding question has been developed into an argument for atheism typically referred to as the 'problem of divine hiddenness'. My goal here is to put forward a new reply. The basic idea is that there is some reason to think that for many of us, our moral conduct would not improve even if God's existence were not subject to doubt. However, immoral conduct in such a state (...) of affairs would be even more immoral, and hence justly subject to greater punishment, than it is in a state of affairs in which God's existence is subject to doubt. As such, God mercifully remains 'hidden' in order to limit our moral culpability. (shrink)

It is shown how, starting with the de Broglie–Bohm pilot-wave theory, one can construct a new theory of the sort envisioned by several of QM’s founders: a Theory of Exclusively Local Beables (TELB). In particular, the usual quantum mechanical wave function (a function on a high-dimensional configuration space) is not among the beables posited by the new theory. Instead, each particle has an associated “pilot-wave” field (living in physical space). A number of additional fields (also fields on physical space) maintain (...) what is described, in ordinary quantum theory, as “entanglement.” The theory allows some interesting new perspective on the kind of causation involved in pilot-wave theories in general. And it provides also a concrete example of an empirically viable quantum theory in whose formulation the wave function (on configuration space) does not appear—i.e., it is a theory according to which nothing corresponding to the configuration space wave function need actually exist. That is the theory’s raison d’etre and perhaps its only virtue. Its vices include the fact that it only reproduces the empirical predictions of the ordinary pilot-wave theory (equivalent, of course, to the predictions of ordinary quantum theory) for spinless non-relativistic particles, and only then for wave functions that are everywhere analytic. The goal is thus not to recommend the TELB proposed here as a replacement for ordinary pilot-wave theory (or ordinary quantum theory), but is rather to illustrate (with a crude first stab) that it might be possible to construct a plausible, empirically viable TELB, and to recommend this as an interesting and perhaps-fruitful program for future research.

It is typically thought that miracles, if they occur, can provide evidence for the truth of religious doctrine. But what if different miracles occur attesting to the truth of different and incompatible religions? How is one to decide between the truth of the supposed revelations? Much of Locke’s short work, A Discourse of Miracles, is concerned with this question. Here I summarize and evaluate Locke’s answer.

In Logic and the Way of Jesus, philosophy professor Travis Dickinson recaptures the need for a Christian view of reality, highlighting the use of reason and evidence to develop and defend Christian beliefs.

While Dickinson contends that Christians have failed to engage the culture deeply because they have failed to emphasize and value a Christian intellect, he offers (...) encouragement that embracing the life of the Christian mind can impact the world for the cause and kingdom of Christ.

A warm, personal guide to building a strong ethical and moral compass in the midst of today's confusing, scary, global problems. The moral challenges of today are unfamiliar in the history of philosophy. Climate change is the paradigm example of what Travis Rieder calls "The Puzzle" in the way your choices can seem at odds with what the planet urgently needs. How do we decide the right thing to do in the face of a massive collective challenge? Should you (...) drink water from a plastic bottle or not? Drive a Tesla? Or is that just what Elon and all the other corporations want you to think? What makes individual ethics difficult to think about in the case of catastrophic climate change makes ethics difficult to think about in many other contexts as well. The Puzzle, as he explains, is everywhere now. The chapters include a lively, meaningful tour of traditional moral reasoning looking at the contributions of Plato, Hegel, and Kant among others. But they could not grasp The Puzzle we now face. Old fashioned exercises like trolley problems involving sacrificing one person on this track for a bunch of people on the other don't address the huge consequential and complex crises our global community faces today. The tools most of us unthinkingly rely on when we try to do the right thing don't help when it comes to reasoning about individual responsibility for large collective problems. Expanding our suite of ethical concepts is now urgently required. Rieder defines exactly how to change our thinking, addressing mundane issues like bottled water to the biggies like whether to have children. This is a way to live a morally decent life in the scary, always complicated world we and our children live in. It's how to build your own Catastrophe Ethics. (shrink)

Neonatal intensive care units represent simultaneously one of the great success stories of modern medicine, and one of its most controversial developments. One particularly controversial issue is the resuscitation of extremely preterm infants. Physicians in the United States generally accept that they are required to resuscitate infants born as early as 25 weeks and that it is permissible to resuscitate as early as 22 weeks. In this article, I question the moral pressure to resuscitate by criticizing the idea that resuscitation (...) in this context “saves” a human life. Our radical medical advancements have allowed us to intervene in the life of a human before it makes sense to say that such an intervention “saves” someone; rather, what the physician does in resuscitating and treating an extremely preterm infant is to take over creating it. This matters, I argue, because “rescues” are much more morally urgent than “creations.”. (shrink)

The value alignment problem for artificial intelligence (AI) asks how we can ensure that the “values”—i.e., objective functions—of artificial systems are aligned with the values of humanity. In this paper, I argue that linguistic communication is a necessary condition for robust value alignment. I discuss the consequences that the truth of this claim would have for research programmes that attempt to ensure value alignment for AI systems—or, more loftily, those programmes that seek to design robustly beneficial or ethical artificial agents.

Marc Lange has recently raised three objections to the account of minimal model explanations offered by Robert Batterman and Collin Rice. In this article, I suggest that these objections are misguided. I suggest that the objections raised by Lange stem from a misunderstanding of the what it is that minimal model explanations seek to explain. This misunderstanding, I argue, consists in Lange’s seeing minimal model explanations as relating special types of models to particular target systems rather than seeing minimal model (...) explanations as looking to explain robust patterns of behavior that are exhibited by a variety of physically diverse systems.

It is an underappreciated fact within the philosophical literature on laws of nature that many scientific laws require the aid of a supporting cast of additional modelling ingredients (such as boundary conditions, material parameters, interfacial stipulations, rigidity constraints, and so on) in order to perform their traditional role in scientific inquiry. In this paper, I suggest that this underappreciated fact spells trouble for some recent reformulations of David Lewis's Best Systems Account (BSA) of laws of nature. Under the auspices of (...) 'pragmatic Humeanism,' several philosophers have recently argued that the criteria of strength and simplicity that lay at the heart of Lewis's original formulation should be replaced with alternatives that are more sensitive to the role that laws play in scientific practice. Although the criteria that these philosophers put forward differ in a variety of ways, they are primarily concerned with the ability of laws to furnish us with predictions and encode information. This, I suggest, is a problem. If it is true that many scientific laws do not on their own perform some of the roles with which they are traditionally associated, then they are unlikely in isolation to make meaningful contributions to the predictive strength of a system or encode information about particular systems. Such laws are thus unlikely to end up in the best system, and so these accounts will have trouble conferring lawhood upon them. (shrink)

Complex work in teams requires coordination across team members and their technology as well as the ability to change and adapt over time to achieve effective performance. To support such complex interactions, recent efforts have worked toward the design of adaptive human-autonomy teaming systems that can provide feedback in or near real time to achieve the desired individual or team results. However, while significant advancements have been made to better model and understand the dynamics of team interaction and its relationship (...) with task performance, appropriate measures of team coordination and computational methods to detect changes in coordination have not yet been widely investigated. Having the capacity to measure coordination in real time is quite promising as it provides the opportunity to provide adaptive feedback that may influence and regulate teams’ coordination patterns and, ultimately, drive effective team performance. A critical requirement to reach this potential is having the theoretical and empirical foundation from which to do so. Therefore, the first goal of the paper is to review approaches to coordination dynamics, identify current research gaps, and draw insights from other areas, such as social interaction, relationship science, and psychotherapy. The second goal is to collate extant work on feedback and advance ideas for adaptive feedback systems that have potential to influence coordination in a way that can enhance the effectiveness of team interactions. In addressing these two goals, this work lays the foundation as well as plans for the future of human-autonomy teams that augment team interactions using coordination-based measures. (shrink)

The ontology of Bohmian mechanics includes both the universal wave function and particles. Proposals for understanding the physical significance of the wave function in this theory have included the idea of regarding it as a physically-real field in its 3N-dimensional space, as well as the idea of regarding it as a law of nature. Here we introduce and explore a third possibility in which the configuration space wave function is simply eliminated—replaced by a set of single-particle pilot-wave fields living in (...) ordinary physical space. Such a re-formulation of the Bohmian pilot-wave theory can exactly reproduce the statistical predictions of ordinary quantum theory. But this comes at the rather high ontological price of introducing an infinite network of interacting potential fields which influence the particles’ motion through the pilot-wave fields. We thus introduce an alternative approach which aims at achieving empirical adequacy with a more modest ontological complexity, and provide some preliminary evidence for optimism regarding the program of trying to replace the configuration space wave function with a set of fields in ordinary physical space.

The growing field of machine morality has becoming increasingly concerned with how to develop artificial moral agents. However, there is little consensus on what constitutes an ideal moral agent let alone an artificial one. Leveraging a recent account of heroism in humans, the aim of this paper is to provide a prospective framework for conceptualizing, and in turn designing ideal artificial moral agents, namely those that would be considered heroic robots. First, an overview of what it means to be an (...) artificial moral agent is provided. Then, an overview of a recent account of heroism that seeks to define the construct as the dynamic and interactive integration of character strengths and situational constraints that afford the opportunity for moral behavior . With this as a foundation, a discussion is provided for what it might mean for a robot to be an ideal moral agent by proposing a dynamic and interactive connectionist model of robotic heroism. Given the limited accounts of robots engaging in moral behavior, a case for extending robotic moral capacities beyond just being a moral agent to the level of heroism is supported by drawing from exemplar situations where robots demonstrate heroism in popular film and fiction.

Alternative Conceptions of the Spiritual engages with polytheism, henotheism, pandeism, cosmopsychism, world-soul ontologies, animism and theophanism as propounded by recent philosophers and by members of lesser-known non-western faith communities, new religious movements, and esoteric groups. Treating the topics with comparative philosophical exploration and assessment, Travis Dumsday brings Christian doctrines, specifically from an Eastern Orthodox perspective, into dialogue with these alternative viewpoints.

We use tools from evolutionary game theory to examine how power might influence the cultural evolution of inequitable conventions between discernible groups (such as gender or racial groups) in a population of otherwise identical individuals. Similar extant models always assume that power is homogeneous across a social group. As such, these models fail to capture situations where individuals who are not themselves disempowered nonetheless end up disadvantaged in bargaining scenarios by dint of their social group membership. Our models show that (...) even when most individuals in two discernible sub-groups are relevantly identical, powerful individuals can affect the social outcomes for their entire group under a range of conditions; this results in power by association for their in-group and a bargaining disadvantage for their out-group.

The problem of divine hiddenness has in the recent literature joined the problem of evil as one of the principal positive arguments for atheism. My chief goal here is to mine Aquinas’s metaphysics and natural theology for a distinctively Thomistic response, making particular use of a neglected text in which he considers a similar issue. Towards the end of the paper I also consider some resources provided by Aquinas’s interpretation of revealed theology.

This paper applies the theoretical criteria laid out by D’Arms et al. to various aspects of evolutionary models of signalling. The question that D’Arms et al. seek to answer can be formulated as follows: Are the models that we use to explain the phenomena in question conceptually adequate? The conceptual adequacy question relates the formal aspects of the model to those aspects of the natural world that the model is supposed to capture. Moreover, this paper extends the analysis of D’Arms (...) et al. by asking the following additional question: Are the models that we use sufficient to explain the phenomena in question? The sufficiency question asks what formal resources are minimally required for the model to get the right results most of the time. (shrink)

Charles Travis presents a series of essays on philosophy of perception, inspired by the insights of Gottlob Frege.

In support of logical nihilism, according to which there are no logical laws, Gillian Russell offers purported counterexamples to two laws of logic. Russell’s examples rely on cleverly constructed predicates not found in ordinary English. I show that similar apparent counterexamples to the same logical laws can be constructed without exotic predicates but using only what ordinary language provides. We correctly analyze such arguments so that they do not actually constitute counterexamples to any logic laws. I claim that we can (...) and should do the same for Russell’s arguments. (shrink)

The debate over the explanatory nature of cognitive models has been waged mostly between two factions: the mechanists and the dynamical systems theorists. The former hold that cognitive models are explanatory only if they satisfy a set of mapping criteria, particularly the 3M/3m* requirement. The latter have argued, pace the mechanists, that some cognitive models are both dynamical and constitute covering-law explanations. In this paper, I provide a minimal model interpretation of dynamical cognitive models, arguing that this both provides needed (...) clarity to the mechanist versus dynamicist divide in cognitive science and also paves the way towards further insights about scientific explanation generally.
