When the opossum feels threatened, she becomes paralyzed. Her body temperature plummets, her breathing and heart rates drop to a minimum, and her glands simulate the smell of a putrefying corpse. Playing Possum explores what the opossum and other creatures can teach us about how we and other species understand mortality, and demonstrates that the concept of death, far from being a uniquely human attribute, is widespread in the animal kingdom. -/- With humor and empathy, Susana Monsó tells the stories (...) of ants who attend their own funerals, chimpanzees who clean the teeth of their dead, dogs who snack on their caregivers, crows who avoid the places where they saw a carcass, elephants obsessed with collecting ivory, and whales who carry their dead for weeks. Monsó, one of today’s leading experts on animal cognition and ethics, shows how there are more ways to conceive of mortality than the human way, and challenges the notion that the only emotional reactions to death worthy of our attention are ones that resemble our own. -/- Blending philosophical insight with new evidence from behavioral science and comparative psychology, Playing Possum dispels the anthropocentric biases that cloud our understanding of the natural world, and reveals that, when it comes to death and dying, we are just another animal.

Neuroscience hasn’t shown how quite similar sensory circuits encode quite different colors and other qualia, nor how the unified pictorial form of images is encoded, nor how these codes yield conscious images. Neuroscience’s fixation here on cortical codes may be the culprit. Treating conscious images partly as retinal substances may avoid these problems. The evidence for conscious retinal images is that (a) the cortical codes for images are quite problematic, (b) injecting retinas with certain genes turns dichromats into trichromats without (...) cortical help, (c) retinas can discern colors by themselves without cortex, (d) retinal distortions appear in images but cortical distortions don’t, (e) retinal detectors support finely detailed colors, but V4 detectors don’t, due to their big receptive fields, (f) retinal activity has pictorial form, but viable cortical codes for pictorial form don’t exist. So, the colors and unified pictorial form of images arguably arise mainly across arrays of retinal detectors—not from abstract cortical codes. Images may be hidden in retinal activity beyond what EEGs show of it (cf. Strawson’s monism). Also, cortex refines these retinal images but cortical impairment (anesthesia, lesions, etc.) blocks awareness of them, for they’re no longer accessible to the mind’s subject-centered consciousness, resident in cortex. This proposal is largely testable and based in recent evidence. It avoids neuroscience’s elusive, problematic coded images and enigmatic explanations of how they become conscious. (shrink)

Arguments from consciousness to God’s existence (ACs) contend that physicalism is too problematic to explain the mind’s ultimate source. They add that theism probably better explains this source in terms of God making us in his own image (with conscious, unified, rational minds). But ACs are problematic too. First, physicalism has various competitors beside theism. Russellian monism and dual-aspect theory are examples. Second, all these theories, including theism, are seriously flawed. For example, it’s tied to traditional dualism, which has causal (...) issues (according to Murphy, Churchland, and other physicalists). But we argue that this theistic dualism can be refined to avoid its issues—and the issues in all other theories. So, it probably explains the mind’s origin better than other theories. We rely here on Lowe’s dualism, where the mind’s subject exists immaterially yet spatially, and is a unified, simple entity (unlike neural aggregates with their quite separate parts). This turns the tables on Churchland, Murphy, and other advocates for scientism. -/- . (shrink)

Russellian monism (RM) attributes experience to the intrinsic nature of physics’ abstract mathematical accounts of the world. It’s touted as a promising mind-body solution, for it avoids dualist and physicalist issues. Yet this status is imperiled by its deeply obscure ideas of mental combination, protophenomenal entities, emergent experience, grounded abstractions, et cetera. This “metaphysical magical mystery tour” may render RM as problematic as competing views. A clear, simple panpsychism akin to Strawson’s might avoid these issues. In this theory (NPP), experience (...) is the real, underlying nature of matter-energy, hidden beyond its sensory appearances. NPP may avoid panpsychist combination problems by showing how neurons can electrically bind their minimal experience to form percepts, thoughts, and subjects. This might explain combination in testable ways, while RM instead turns to questionable microsubjects and binding mechanisms. NPP’s virtues are its metaphysical simplicity, empirical support, testable foundations—and its avoidance of the issues in RM and other standard theories. It might point to a mind-body solution.

Evaluativists hold that psychiatric disorders have a factual and evaluative dimension and recognize that psychiatric patients have an active role in shaping their symptoms, influencing the development of their disorders, and the outcome of psychiatric therapy. This is reflected in person-centered approaches that explicitly consider the role of values in psychiatric conceptualization, classification, and decision-making. In this respect, in light of the recent partnership between Fulford’s value-based practice (VBP), and Stanghellini’s phenomenological-hermeneutic-dynamical (P.H.D) psychotherapy method, this paper presents a comparative analysis (...) of two person-centered approaches to psychiatric care currently discussed within the literature. I claim that while these approaches share some core ideas, they also present important divergences concerning their axiological underpinnings, which could potentially compromise their partnership. In particular, by exploring their theoretical, practical, and ethical dimensions, I show that these models have different conceptions of what values are, which, in turn, affect their understanding of how values relate to the person and how clinicians can identify them. Finally, I argue that although Fulford’s and Stanghellini’s approaches are prima facie compatible and complementary, developing a “combined analytic-plus-phenomenological form of values-based practice” should address fundamental conceptual issues if it is to become a consistent and coherent method for psychiatric care.

From organic synthesis to quantum chemical calculation, chemists interact with chemical substances in a wide variety of ways. But what even is a chemical substance? My aim is to propose a notion of chemical substance that is consistent with the way in which chemical substances are individuated in chemistry, addressing gaps in previous conceptions of chemical substance. Water is employed as a case study to develop the account, not only because it is a familiar example of a chemical substance, but (...) also because its structural peculiarities make it an ideal test case for drawing out potential issues and limitations. Examining four distinct views of chemical substance—the microstructural, thermodynamic, purification, and a functional/relational account—I conclude that each has considerable drawbacks when used as a standalone concept. However, these accounts are not rendered obsolete, but are combined into a semi-pluralist conceptual patchwork. My interactive account of chemical substance is consistent with existing substance descriptions and chemical practice. (shrink)

The problem considered in this chapter emerges from the tension we find when looking at the design and architecture of chatbots on the one hand and their conversational aptitude on the other. In the way that LLM chatbots are designed and built, we have good reason to suppose they don't possess second-order capacities such as intention, belief or knowledge. Yet theories of conversation make great use of second-order capacities of speakers and their audiences to explain how aspects of interaction succeed. (...) As we can all bear witness to now though, at the point of use chatbots appear capable of performing language tasks at a level close to that of humans. This creates a tension when we consider something like, for example, the classic Gricean theory of implicature. On a broad summary of this type of account, to utter p and implicate q requires the reflexive occurrence of an audience supposing a speaker believes that q, and the speaker believing that their audience can determine they believe it when they utter p. So taken at face value, if a chatbot doesn’t have the capacity for belief, then either in their role as speaker or audience, they would not seem capable of either generating or comprehending implicatures. Yet on the surface it does seem that chatbots are capable of dealing with (some) implicatures, and as such it raises questions about how we should then correlate this with what we think occurs in cases of implicature with chatbots.

There is a general conception of levels in philosophy which says that the world is arrayed into a hierarchy of levels and that there are different modes of analysis that correspond to each level of this hierarchy, what can be labelled the ‘Hierarchical Correspondence View of Levels” (or HCL). The trouble is that despite its considerable lineage and general status in philosophy of science and metaphysics the HCL has largely escaped analysis in specific domains of inquiry. The goal of this (...) paper is to take up a recent call to domain-specificity by examining the role of the HCL in cognitive science. I argue that the HCL is, in fact, a conception of levels that has been employed in cognitive science and that cognitive scientists should avoid its use where possible. The argument is that the HCL is problematic when applied to cognitive science specifically because it fails to distinguish two important kinds of shifts used when analysing information processing systems: shifts in grain and shifts in analysis. I conclude by proposing a revised version of the HCL which accommodates the distinction. (shrink)

Efforts by governments, firms, and patients to deliver pioneering drugs for critical health needs face a challenge of diminishing efficiency in developing those medicines. While multi-sectoral collaborations involving firms, researchers, patients, and policymakers are widely recognized as crucial for countering this decline, existing incentives to engage in drug development predominantly target drug manufacturers and thereby do little to stimulate collaborative innovation. In this mini review, we consider the unexplored potential within pharmaceutical regulations to create novel incentives to encourage a diverse (...) set of actors from the public and private spheres to engage in the kind of collaborative knowledge exchange requisite for fostering enhanced innovation in early drug development.

How do brains create all our different colors, pains, and other conscious qualities? These various qualia are the most essential aspects of consciousness. Yet standard neuroscience (primarily based on synaptic information processing) has not found the synaptic-firing codes, sometimes described as the “spike code,” to account for how these qualia arise and how they unite to form complex perceptions, emotions, et cetera. Nor is it clear how to get from these abstract codes to the qualia we experience. But electromagnetic field (...) (versus synaptic) approaches to how qualia arise have been offered in recent years by Pockett, McFadden, Jones, Bond, Ward and Guevera, Keppler and Shani, Hunt and Schooler, et cetera. These EM-field approaches show promise in offering more viable accounts of qualia. Yet, until now, they have not been evaluated together. We review various EM field theories of qualia, highlight their strengths and weaknesses, and contrast these theories with standard neuroscience approaches. -/- . (shrink)

Where is consciousness? Neurobiological theories of consciousness look primarily to synaptic firing and “spike codes” as the physical substrate of consciousness, although the specific mechanisms of consciousness remain unknown. Synaptic firing results from electrochemical processes in neuron axons and dendrites. All neurons also produce electromagnetic (EM) fields due to various mechanisms, including the electric potential created by transmembrane ion flows, known as “local field potentials,” but there are also more meso-scale and macro-scale EM fields present in the brain. The functional (...) role of these EM fields has long been a source of debate. We suggest that these fields, in both their local and global forms, may be the primary seat of consciousness, working as a gestalt with synaptic firing and other aspects of neuroanatomy to produce the marvelous complexity of minds. We call this assertion the “electromagnetic field hypothesis.” The neuroanatomy of the brain produces the local and global EM fields but these fields are not identical with the anatomy of the brain. These fields are produced by, but not identical with, the brain, in the same manner that twigs and leaves are produced by a tree’s branches and trunk but are not the same as the branches and trunk. As such, the EM fields represent the more granular, both spatially and temporally, aspects of the brain’s structure and functioning than the neuroanatomy of the brain. The brain’s various EM fields seem to be more sensitive to small changes than the neuroanatomy of the brain. We discuss issues with the spike code approach as well as the various lines of evidence supporting our argument that the brain’s EM fields may be the primary seat of consciousness. This evidence (which occupies most of the paper) suggests that oscillating neural EM fields may make firing in neural circuits oscillate, and these oscillating circuits. may help unify and guide conscious cognition.
