It was shown in Dirac A117, 610; A118, 351, 1928) that the ultra-violet divergence in quantum electrodynamics is caused by a violation of the time-energy uncertainly relationship, due to the implicit assumption of infinitesimal time information. In Wheeler et al. it was shown that Einstein’s special theory of relativity and Maxwell’s field theory have mathematically equivalent dual versions. The dual versions arise from an identity relating observer time to proper time as a contact transformation on configuration space, which leaves phase (...) space invariant. The special theory has a dual version in the sense that, for any set of n particles, every observer has two unique sets of global variables \\) and \\) to describe the dynamics, where \ is the canonical center of mass. In the \\) variables, time is relative and the speed of light is unique, while in the \\) variables, time is unique and the speed of light is relative with no upper bound. In the Maxwell case, the two sets of particle wave equations are not equivalent. The dual version contains an additional longitudinal radiation term that appears instantaneously with acceleration, leading to the prediction that radiation from a cyclotron will not produce photoelectrons. A major outcome is the dual unification of Newtonian mechanics and classical electrodynamics with Einstein’s special theory of relativity, without the need for point particles, without a self-energy divergency and, without need for the problematic Lorentz–Dirac equation. The purpose of this paper is to introduce the dual theory of relativistic quantum mechanics. In our approach, we obtain three distinct dual relativistic wave equations that reduce to the Schrödinger equation when minimal coupling is turned off. We show that the dual Dirac equation provides a new formula for the anomalous magnetic moment of a charged particle. We can obtain the exact value for the electron g-factor and phenomenological values for the muon and proton g-factors. (shrink)

In The Entangled Brain, Pessoa criticizes standard approaches in cognitive neuroscience in which the brain is seen as a functionally decomposable, modular system with causal operations built up hierarchically. Instead, he advocates for an emergentist perspective whereby dynamic brain networks are associated, not with traditional psychological categories, but with behavioral functions characterized in evolutionary terms. Here, we raise a number of concerns with such a radical approach. We ultimately believe that while much revision to cognitive neuroscience is welcome and needed, (...) Pessoa’s more radical proposals may be counterproductive. (shrink)

A number of authors have recently cited phenomenal effects of covert attention as a source of objection to representationalism. These authors maintain that covert attention brings about changes to phenomenology that cannot be explained by changes in representational content. This paper deals with two related issues that are central to this debate: (1) how attention interacts with representational content, and (2) how variations in the precision or determinacy of representational content should be incorporated into representationalist accounts of perceptual phenomenology. I (...) address these issues in the course of responding to several recent anti-representationalist arguments that have been advance by Ned Block. I argue that attention can increase the precision of range content and that this provides a basis for defusing both the concerns raised by Block and more general concerns related to covert attention. I conclude by situating my response with respect to analogous proposals that have been developed around the determination relation. (shrink)

Despite a heightened political discourse surrounding food choices, few studies have identified connections between political beliefs and consumer perceptions. Using gluten as an example, this article identifies how political opinions relate to opinions of food products. If an avoidance of gluten is a biological condition and not a social construct, there should be no correlation between political opinions and gluten avoidance. Our study uncovers a complex relationship between the social construction of gluten avoidance and the potential role of political views. (...) Perhaps most surprising, we find that supporters of Donald Trump are more likely to identify as avoiding gluten, relative to non-supporters. Findings suggest that future research might benefit from considering the political beliefs of consumers when estimating models of food demand. (shrink)

Functional robustness refers to a system’s ability to maintain a function in the face of perturbations to the causal structures that support performance of that function. Modularity, a crucial element of standard methods of causal inference and difference-making accounts of causation, refers to the independent manipulability of causal relationships within a system. Functional robustness appears to be at odds with modularity. If a function is maintained despite manipulation of some causal structure that supports that function, then the relationship between that (...) structure and function fails to be manipulable independent of other causal relationships within the system. Contrary to this line of reasoning, I argue that functional robustness often attends feedback control, rather than failures of modularity. Feedback control poses its own challenges to causal explanation and inference, but those challenges do not undermine modularity—and indeed, modularity is crucial to grappling with them. (shrink)

Psychedelic or ecodelic medicines (e.g., psilocybin, ayahuasca, iboga) for the care and treatment of addiction, post‐traumatic stress disorder, cancer, cluster headaches, anxiety, and depression have surged to the forefront of discussions about mental health in the US, leading to the emergence of well‐capitalized biotech companies offering multimillion‐dollar IPOs. Venture capital website Pitchbook reports “continuing investor interest and growing acceptance of what until recently was seen as a fringe area of medicine.” As scholars, activists, and practitioners who have been healed by (...) these medicines and applaud the recent wave of decriminalization after a long, strange trip of mass incarceration and widespread dangerous misinformation, we look forward to a culture that makes these medicines available in a safe and affordable way that respects the lineages of the knowledges that are essentially and not accidentally bundled with these plants—Indigenous and counterculture wisdoms for whom these medicines were never “fringe,” but always foundational. In place of corporadelia's pursuit of standardization, we emphasize the care and wisdom of the Indigenous and countercultural teachings—traditions that have made psychedelics available to the emerging corporate/research partnership in the first place. These knowledge traditions offer foils to the ongoing translation of university peer‐reviewed research into market copy, technical articles, and IPOs, and the concomitant emergence of psychedelic pundits. In particular, we examine instances where prominent researchers have overstated the findings of existing clinical trials in public‐facing representations of the field. We argue that these corporate priorities and tactics are being aided by a new wave of psychedelic “thought leaders” who seek to delegitimize non‐hierarchical approaches to knowledge production and community support within a psychedelic commons. While prominent psychedelic psychiatrists and behaviorists are focused on rooting out and transforming individual habits of mind, we argue that there is another, latent potential for psychedelics to draw attention to—and transform—the invisible, hegemonic infrastructures and ideologies that subtly naturalize and perpetuate deeply unequal societies.

This work stresses the illogical manner in which mathematics has developed, the question of applied mathematics as against 'pure' mathematics, and the challenges to the consistency of mathematics' logical structure that have occurred in the twentieth century.

Theory-of-mind (ToM) involves modeling an individual’s mental states to plan one’s action and to anticipate others’ actions through recursive reasoning that may be myopic (with limited recursion) or predictive (with full recursion). ToM recursion was examined using a series of two-player, sequential-move matrix games with a maximum of three steps. Participants were assigned the role of Player I, controlling the initial and the last step, or of Player II, controlling the second step. Appropriate for the assigned role, participants either anticipated (...) or planned Player II’s strategy at the second step, and then determined Player I’s optimal strategy at the first step. Participants more readily used predictive reasoning as Player II (i.e., planning one’s own move) than as Player I (i.e., anticipating an opponent’s move), although they did not differ when translating reasoning outcome about the second step to optimal action in the first step. Perspective-taking influenced likelihood of predictive reasoning, but it did not affect the rate at which participants acquired it during the experimental block. We conclude that the depth of ToM recursion (related to perspective-taking mechanisms) and rational application of belief–desire to action (instrumental rationality) constitute separate cognitive processes in ToM reasoning.

Subjective feelings of familiarity associated with a stimulus tend to be strongest when specific information about the previous encounter with the stimulus is difficult to retrieve . Recognizing: The judgment of previous occurrence. Psychological Review, 87, 252–271.]). When a stimulus has been encountered previously and the circumstances of the encounter cannot be recollected, additional cognitive resources may be directed toward recollection processes; this resource allocation is accompanied by autonomic arousal [Dawson, M. E., Filion, D. L., & Schell, A. M. . (...) Is elicitation of the autonomic orienting response associated with allocation of processing resources?. Psychophysiology, 26, 560–572]. One easily measurable index of autonomic arousal is the skin conductance response . In the present study, participants studied lists of words and then gave recognition ratings to briefly displayed and masked studied and nonstudied test words while their SCRs were monitored. Results revealed a relationship between recognition ratings and the temporal characteristics of the SCR, supporting the idea that feelings of familiarity are indeed “feelings” in that they stem from autonomic arousal associated with cognitive resource allocation.

Braiding personal narratives and philosophical meditations, throughout this essay I reflect on what it means to care for more-than-human others when doing so often leaves us utterly compromised and when the broader conditions under which we coexist on earth with others are themselves antithetical to ecological continuity. Ecologically, the essay is situated in the midst of Cook Forest, an 8,500-acre public park in northwest Pennsylvania, where ancient eastern hemlocks (Tsuga canadensis) find themselves imperiled by the hemlock woolly adelgid (Adelges tsugae), (...) an aphid-like insect native to east Asia. Considering responses to the adelgid at Cook Forest, I engage in a series of philosophi­cal and ethical meditations about ecological care—about its complicities and its conditions of (im)possibility. And, finally, in conversation with Theodor Adorno and Judith Butler, I reflect upon how critique and resistance might open onto still more radical modes of ecological care. (shrink)

While increasing numbers of philosophers have argued for eliminating the retributivist elements of criminal justice systems, their arguments often fall short due to internal inconsistency. Some of the best known of these arguments — such as those provided by Derk Pereboom and Gregg Caruso — rely on the claim that there are moral grounds for rejecting retributivism. In defending this claim, these philosophers typically provide arguments seeking to undermine the type of agent responsibility that they believe is needed to justify (...) retributivism. This is usually followed by an assertion that since the excessive suffering caused by retributivist punishment cannot be justified, it is therefore immoral to preserve remnants of it in our criminal justice systems. This paper — which opposes the moral case against retributivism provided by Pereboom and Caruso, and favors non-moral reasons that recommend rejecting a retributivist approach — is divided into three parts. In part one, I discuss why Pereboom and Caruso are correct in thinking that free will skepticism undercuts the moral justification for retributivism. Part two sets out to explain why their moral case against retributivism fails insofar as it runs afoul of the folk intuitions that are called upon to defend Pereboom’s account of free will skepticism. In part three, I provide a non-moral case against the retributivism that is founded on considerations of self-interest and empathy. (shrink)

Abstract:Dwelling near Lake Superior in the Anthropocene, we uncover a greater intimacy and acquaintance with our earthly responsibilities. Thoughts wash over us like waves as our thinking ebbs and flows between the fact that we must learn to dwell here while also coming to terms with the planetary implications of our very being. That ebb and flow is presented here in a series of waves, which can be read in or out of order, in an orderly or disorderly fashion. These (...) waves crash into one another as we reflect on place, dwelling, hospitality, deep history, enchantment, wildness, and thinking itself. We discover in this mixture an invitation to think more deeply about our responsibilities by contemplating one of the other bodies with which we cohabit the earth: the deep, blue body of Lake Superior.

Erik Wielenberg recently invoked the parent-child analogy in an argument against Christian theism. The argument relies on the claim that a loving parent would never allow her child to feel abandoned in the midst of what feels like gratuitous suffering. In this paper, I offer three clear counterexamples to Wielenberg’s central premise. At the same time, a successful counterexample does not a robust theology of suffering make. To that end, and with a careful eye towards anti-theodical concerns, I defend the (...) need for a more proactive Christian philosophical examination of the role of suffering in a meaningful life.

Conventional theory assumes that economic agents perform at optimal levels of efficiency by definition and this is achieved when individuals behave in a particular fashion. Moreover, neoclassical production theory masks the process by which optimal output can be achieved. I argue that economic theory should be revised to incorporate some key findings of behavioural economics, while retaining the conventional theory’s normative ideal of optimum output whilst rejecting its normative procedural ideals of how to achieve optimality in production. I argue that (...) neoclassical procedures can be expected to yield sub-optimal levels of output and therefore should not be benchmarks for procedural rationality. I present an alternative more realistic and analytically precise specification of the production function related to the fast and frugal heuristics narrative pioneered by Gigerenzer and Leibenstein’s x-efficient theory. This approach incorporates an understanding of the appropriate procedures, psychological and organization variables, decision-making capabilities and end-goals required to achieve optimality in production and, thereby, grow the wealth of nations, thereby enhancing the material wellbeing of the population at large. This also provides us with the tools to better identify economic inefficiency and the conditions that contribute to it. (shrink)

At a time when both scholars and the public demand explanations and answers to key economic problems that conventional approaches have failed to resolve, this groundbreaking handbook of original works by leading behavioral economists offers the first comprehensive articulation of behavioral economics theory. Borrowing from the findings of psychologists, sociologists, political scientists, legal scholars, and biologists, among others, behavioral economists find that intelligent individuals often tend not to behave as effectively or efficiently in their economic decisions as long held by (...) conventional wisdom. The manner in which individuals actually do behave critically depends on psychological, institutional, cultural, and even biological considerations. "Handbook of Contemporary Behavioral Economics" includes coverage of such critical areas as the Economic Agent, Context and Modeling, Decision Making, Experiments and Implications, Labor Issues, Household and Family Issues, Life and Death, Taxation, Ethical Investment and Tipping, and Behavioral Law and Macroeconomics. Each contribution includes an extensive bibliography. (shrink)
