Interactionism

This is an updated version of one section of my essay "Objections to Dualism" prepared for presentation at the 2019 Mountain-Pacific SCP Conference in Las Vegas, April 6-7, 2019.

Jaegwon Kim développe l’argument suivant contre le dualisme psycho-physique : (i) Dans le dualisme, l’esprit est dénué de spatialité. (ii) Or, la relation causale requiert des relations spatiales entre la cause et l’effet. (iii) Par conséquent, dans le dualisme, l’esprit ne peut être ni cause ni effet. Après avoir exposé les détails de cet argument, j’en discute les prémisses. En m’appuyant sur Hume, je montre que la relation causale est concevable sans relation spatiale entre la cause et l’effet. Et en (...) m’appuyant sur la physique contemporaine, je m’intéresse à d’éventuelles relations causales non spatiales. (shrink)

In this chapter, I first review and assess evidence regarding brain damage or neural abnormalities associated with some psychopathologies and cognitive deficits, such as hemispatial neglect, agnosias, amnesia, somatoparaphrenia, and others. It becomes clear just how closely normal mental functioning and consciousness depend upon normal brain functioning as well as how some very specific mental changes occur when, and only when, very specific brain damage occurs. I then explore the metaphysical implications of these results with respect to the nature of (...) mind and consciousness. In particular, I examine the plausibility of materialism, roughly the view that mental processes are brain processes, in light of the evidence discussed and in contrast to a dualist conception of the mind (whereby mental states are not physical in some sense). I also explore the prospects for a conscious afterlife based both on the brain damage evidence adduced and the metaphysical implications discussed. (shrink)

Before I respond to James G. Matlock’s comments on my coedited volume, The Myth of an Afterlife: The Case against Life After Death (MoA), I would like to thank him for taking the time to review such a large volume—and review it conscientiously—even if we ultimately disagree about its import. I would also like to extend my thanks to Journal of Parapsychology editor John Palmer for inviting this response, as it gives me an opportunity to clarify why many secondary issues (...) (and some significant matters) were untouched in the volume. While I find most of Matlock’s complaints specious, they nevertheless underscore the need to clear up misconceptions about the collection’s purpose, some of which are also found in others’ reviews. -/- 1.

In Spinoza’s metaphysics, we encounter many puzzling doctrines that appear to entangle metaphysical notions with cognitive, logical, and epistemic ones. According to him, a substance is that which can be conceived through itself and a mode is that which is conceived through another. Thus, metaphysical notions, substance and mode, are defined through a notion that is either cognitive or logical, being conceived through. He defines an attribute as that which an intellect perceives as constituting the essence of a substance. Intellectual (...) perception, something cognitive, is used to define an attribute, something metaphysical. And he claims that if something exists there is a reason why it exists and if something doesn’t exist there is also a reason why it doesn’t. Thus, a reason, something cognitive or epistemic, is necessary for existence or nonexistence. What are we to make of the intimate connections that Spinoza sees between metaphysical, cognitive, logical, and epistemic notions? Between being and reason? In this book, I argue for what might be called a realist interpretation: although Spinoza is confident that the order of being mirrors the order of reason, he believes that they are two orders, not one. There is inherence over and above conceptual dependence; there is causation in addition to causal explanation; the world has a nature that we can grasp and that our way of grasping it does not interpose an impenetrable conceptual veil between it and us.

One of the most pressing philosophical problems in early modern Europe concerned how the soul and body could form a unity, or, as many understood it, how these two substances could work together. It was widely believed that there were three (and only three) hypotheses regarding the union of soul and body: (1) physical influence, (2) occasionalism, and (3) pre-established harmony. However, in 1763, a fourth hypothesis was put forward by the French thinker André-Pierre Le Guay de Prémontval (1716–1764). Prémontval’s (...) hypothesis, given the grand name of “psychocracy” (i.e., the dominion or the rule of the soul), held that there was a real influence between soul and body, but that this was an immaterial kind of influence as opposed to the physical kind that had been entertained heretofore. Prémontval’s hypothesis is the focus of this paper. I shall begin by sketching out the details of Prémontval’s hypothesis (Section 1), then proceed to consider its claims to constitute a true fourth hypothesis distinct from the other three (Section 2), before closing by briefly considering two objections and the responses either that Prémontval himself made or that may be made on his behalf (Section 3).

I argue against Barbara Montero's claim that Conservation of Energy has nothing to do with physicalism. I reject her reconstruction of the argument for physicalism from CoE, and offer an alternative reconstruction that better captures the intuitions of those who believe that there is a conflict between interactionist dualism and CoE.

Emergent substance dualism is explained in detail and several criticisms are raised against the view.

In this paper I will expose the contents of the Compendium musicae in the light of the Cartesian philosophy. Firstly, I try to comprehend the text as a theory of music based on the nature of sound. To that end, it is important to show the features of the Cartesian philosophy that are already present in the text, such as deductibility, mathematization and mechanism. Secondly, I also try to show the presence of a philosophical problem widely discussed in other parts (...) of Descartes´s work, namely, that of dualism and communicability of substances. In this regard I want to point out that the relation between thought and extension appears in the Compendium as the confession of a supposition. In order to comprehend the sense of this confession I offer an analysis of this text in the light of Descartes’s work. Finally, I propose an alternative interpretation of Cartesian dualism and of the role of musical theory in Cartesian philosophy. (shrink)

According to the Christian doctrine of bodily resurrection, human persons will have an embodied existence in eternity. Many Christian materialists, especially Lynne Rudder Baker, Trenton Merricks, and Kevin Corcoran, argue that the doctrine of bodily resurrection creates serious problems for substance dualism (dualism). These critiques argued that bodily resurrection is made trivial by dualism, that dualism makes it difficult if not impossible to explain why we need to be embodied, or that dualism should be rejected as bodily resurrection is better (...) accounted for by a materialist view. As of yet, there has been no systematic analysis of these arguments in the literature. This paper fills that gap and argues that each of these objections to dualism fail. In making these arguments I make use of neo-Aristotelian metaphysics to provide a theory of embodiment for substance dualism. Accordingly, the body is a complex structural mode of the soul. The essence of the soul is the internal efficient cause and teleological guide of the functions and structure of the body. As such, the body is an ensouled physical structure, not a mere physical machine, but has both physical and non-physical aspects. (shrink)

The link between human nature and human flourishing is undeniable. "A healthy tree cannot bear bad fruit, nor can a diseased tree bear good fruit" (Matt. 7:18). The ontology of the human person will, therefore, ground the nature of human flourishing and thereby sanctification. Spiritual formation is the area of Christian theology that studies sanctification, the Spirit-guided process whereby disciples of Jesus are formed into the image of Jesus (Rom. 8:28-29; 2 Cor. 3:18; 2 Peter 3:18). Until the nineteenth century, (...) there was an overwhelming consensus among Christian thinkers that some form of mind-body (or soul-body) dualism is true of human beings. Recently, that consensus has eroded, and with it the availability of a shared body of knowledge about spiritual formation. Some Christian physicalists argue that dualism is incompatible with central elements of spiritual formation. Neuroscientist Warren Brown and psychologist Brad Strawn offer the only substantive account of spiritual formation from the view of Christian physicalism and its accompanying objections to dualism. It is on their arguments that this chapter focuses. We argue that Brown and Strawn fail to support their incompatibility thesis. Additionally, we argue that Christian physicalism stands in tension with important philosophical and theological foundations of Christian spiritual formation. In doing so we offer a specific form of dualism, the bodily soul view, and explain how this view illuminates the importance of embodiment, our neurological and social development, and hence the important physical aspects of Christian spiritual formation.

The pairing argument aims to demonstrate the impossibility of non-spatial objects (including minds) standing in causal relations. Its chief premises are (roughly) that causation requires pairing relations between causes and effects and that pairing relations require spatial relations. Critics have argued that the first claim suffers from counterexamples involving indeterministic causation. After briefly rehearsing the pairing argument and the objection from indeterministic causation, I offer two ways of revising the pairing argument to meet the objection from indeterministic causation.

This paper argues that a certain kind of substance dualism can adopt the ‘Compatibilist’ solution to the problem of causal exclusion. After sketching a non-Cartesian substance dualism akin to E.J. Lowe’s account, 5-23, 2006, 2008) and considering its shortcomings with respect to mental causation in section one, section two outlines an alternative account of mental causation and argues that this account solves the exclusion problem. Finally, section three considers a challenge to the proposed solution. With the exception of Lowe’s efforts, (...) very little in defense of substance dualist mental causation is to be found in the recent philosophical literature. (shrink)

In this volume, volume 6, I will deal with insight and understanding, meaning and communication and intersubjectivity. (In an appendix I will include a number of –isms, cognitive biases and fallacies that might interfere in, with and distort these things.) The latter is pre-supposed by, present, necessary and operating in all four of these notions when they are employed as verbs. I hope and intend to employ these words and explore them without the need for ghost-in-the-machine like mysterious, mystical and (...) mythical ‘mental’ processes and organs such as ‘mind’ and ‘consciousness’ but by means of different meanings, dimensions, levels of t notions of intersubjectivity. Intersubjectivity enfolds (like a pregnant mother her foetus) insight, understanding, meaning and communication. Intersubjectivity is the beginning, the ground and reason for and the end of all meanings or sense that human beings could have. I am not interested in all the details of insight, experience, understanding, meaning, concepts and ideas, dialogue, discourse, interaction, communication (for example as speculated about by Habermas and his followers, Brandom et al). etc but merely the fact that these things require, assume, presuppose (different aspects, features, functions, processes, etc of) intersubjectivity. For those who are so inclined they could execute experiments (for example in the disciplines of philosophy, psychology, sociology, cognitive sciences, anthropology, etc) to establish that what I state here is a fact and not merely speculate. I will leave speculation - about the activities and nature of the first, second and third person (the public, etc) participants in the activities and process of communication, the question of second and third contingencies, or Habermas’s interactionist cum dialogical intersubjectivity and/or Brandom’s discursive intersubjectivity, the insufficiency of the former’s coordination and the need for synthesis, modes of structuration and the temporal dimensions of communication, threefold semiotic or twofold semiological structuralist theories of signs, theories of individualist or collective learning, action-directing models cultural models, pre-supposed structural features of the social relationships that are involved in communication, the structure parameters of for example the process of communication embedded in an intersubjective context (I would say all the following themselves are intersubjective), as discursive practice, including discourse, argumentation, communication, communication exchange, linguistic communication, everyday communication, interaction, etc - those, especially Continentals and those influenced by them, who suffer from the need for metaphysical speculation and to ontologize in complex terms about the most simple and obvious notions.

David Ray Griffin does not fully come to terms with the fact that science has already abandoned the narrow materialist view of bits of matter pushing each other around. Even as early as Newton's law of gravitation, and most obviously with quantum physics, science has embraced the view that the world consists of relationships (often described as laws) between different types of processes and states.

Possible measurement and testability weaknesses in Sperry's mind-supervenient emergent interactionism "argument by analogy" model are described. An alternative brain-supervenient interactionism that addresses the weaknesses of Sperry's mind-brain model is presented. The alternative model, Neurological Positivism - a systems-theoretical evolutionary epistemology - proposes that the measurable energy quality of the algorithmic organization of the Darwinian brain supervenes that of cultural mental models and thus downwardly influences the brain circuitry patterns that underlie them. Brain and mind are defined in interrelated energy terms (...) within the context of the self-referential maximum-power principle. The equivalence of maximum-power principle energy hierarchies to chaotic/fractal dynamical designs is described. The production of mental models through reflective thinking is defined as an emergent dimension of energetic self-referencing by the brain operating in accordance with the maximum-power principle. It is concluded that within the context of NP the brain-mind relationship constitutes an "uneven" central state energy identity, with brain supervenient, when brain-mind relative energy qualities are taken into account.

The mind-body problem is one of the main centers of reflexion of contemporary philosophy. Generally coming from the supposed failure of the Cartesian interactionist dualism, most philosophers of the mind adopt a physicalist ontology. However, according to Popper, this one seems to meet with insuperable difficulties: it can’t give physicalist explanation of rationality and freedom, of qualia; it can’t suggest a satisfactory explanation of the implementation of logical standards. That is why, as Popper explains in The Self and its Brain, (...) materialistic theories of the mind turn into epiphenomenalism or eliminativism. Popper thinks that all these criticisms of materialism allow to conceive the possibility of spiritual nature of the mind.RésuméLe problème de l’âme et du corps est une question centrale de la philosophie contemporaine. Tenant compte de l’échec du cartésianisme, l’immense majorité des philosophes contemporains adopte une ontologie matéria­liste. Selon Popper, toutefois, ce matérialisme est incapable de rendre compte de l’argumentation, de la liberté humaine ainsi que de la nature des qualia ; le matérialisme ne peut non plus donner une explication satisfaisante de l’implémentation des normes logiques. C’est pourquoi, comme Popper l’explique dans The Self and its Brain, les conceptions matérialistes de l’esprit tombent dans l’épiphénoménalisme ou l’éliminativisme. Popper estime que l’ensemble de ces critiques permet de concevoir la possibilité de la non-matérialité de l’âme. (shrink)

The Exclusion Argument for physicalism maintains that since (1) every physical effect has a sufficient physical cause, and (2) cases of causal overdetermination are rare, it follows that if (3) mental events cause physical events as frequently as they seem to, then (4) mental events must be physical in nature. In defence of (1), it is sometimes said that (1) is supported if not entailed by conservation laws. Against this, I argue that conservation laws do not lend sufficient support to (...) (1) to render its denial ‘unscientific’, and that those who accept (3) and deny (4) may consequently respond to the Exclusion Argument by denying (1) without thereby setting themselves at odds with current science. I also argue that conservation laws are compatible with (3) and the negation of (4), and that one can therefore accept conservation laws and (3) while denying both (1) and (4). (shrink)

This article aims to review the standard objections to dualism and to argue that will either fail to convince someone committed to dualism or are flawed on independent grounds. I begin by presenting the taxonomy of metaphysical positions on concrete particulars as they relate to the dispute between materialists and dualists, and in particular substance dualism is defined. In the first section, several kinds of substance dualism are distinguished and the relevant varieties of this kind of dualism are selected. The (...) remaining sections are analyses of the standard objections to substance dualism : It is uninformative, has troubles accounting for soul individuation, causal pairing and interaction, violates laws of physics, is made implausible by the development of neuroscience and it postulates entities beyond necessity. I conclude that none of these objections is successful. (shrink)

The traditional conception of knowledge is justified, true belief. If one looks at a modern textbook on epistemology, the great bulk of questions with which it deals are to do with personal knowledge, as embodied in beliefs and the proper experiences that someone ought to have had in order to have the right (or justification) to know. I intend to argue that due to the explosive growth of knowledge whose domain is “outside the head”, this conception has outlived its relevance. (...) -/- On the other hand, Karl Popper’s (1934) Falsificationism, with its emphasis on the objective character of knowledge, is not only a sounder, but also a more appropriate theory of knowledge for understanding the nature and growth of civilization. Later, Popper (1945) generalized this approach to obtain critical rationalism, in which all claims to knowledge, whether scientific or otherwise, are understood as objective solutions to objective problems and can be evaluated by other non-observational - types of criticism. I will first argue that Popper’s methodology is quite suited to the view that knowledge is an objective autonomous product and then adduce his theory of world 3, an ontology that neatly wraps up various considerations. World 3 is the domain of abstract products of the human mind that now have a life of their own, outside of human heads: theories, arguments, problems, plans, etc. I then adduce some other arguments for the autonomous quality of knowledge.

General Process Theory (GPT) is a new (non-Whiteheadian) process ontology. According to GPT the domains of scientific inquiry and everyday practice consist of configurations of ‘goings-on’ or ‘dynamics’ that can be technically defined as concrete, dynamic, non-particular individuals called general processes. The paper offers a brief introduction to GPT in order to provide ontological foundations for research programs such as interactivism that centrally rely on the notions of ‘process,’ ‘interaction,’ and ‘emergence.’ I begin with an analysis of our common sense (...) concept of activities, which plays a crucial heuristic role in the development of the notion of a general process. General processes are not individuated in terms of their location but in terms of ‘what they do,’ i.e., in terms of their dynamic relationships in the basic sense of one process being part of another. The formal framework of GPT is thus an extensional mereology, albeit a non-classical theory with a non-transitive part-relation. After a brief sketch of basic notions and strategies of the GPT-framework I show how the latter may be applied to distinguish between causal, mechanistic, functional, self-maintaining, and recursively self-maintaining interactions, all of which involve ‘emergent phenomena’ in various senses of the term.

_Philosophy of Mind: Contemporary Readings_ is a comprehensive anthology that draws together leading philosophers writing on the major topics within philosophy of mind. Robb and O'Connor have carefully chosen articles under the following headings: *Substance Dualism and Idealism *Materialism *Mind and Representation *Consciousness Each section is prefaced by an introductory essay by the editors which guides the student gently into the topic in which leading philosophers are included. The book is highly accessible and user-friendly and provides a broad-ranging exploration of (...) the subject. Ideal for any philosophy student, this book will prove essential reading for any philosophy of mind course. The readings are designed to complement John Heil's _Philosophy of Mind: A Contemporary Introduction, Second edition _, although the anthology can also be used as a stand-alone volume. (shrink)

This article compares Wolfgang Köhler's pioneering field theory of the consciousness–brain relation with Benjamin Libet's conscious mental field theory and Karl Popper's mental force field hypothesis. In the discussion of Köhler's theory we devote special attention to his analysis of problems of sense perception and to his explanation of figural after-effects. Both Libet and Popper take consciousness to causally interact with the brain, and we argue that even Köhler presupposes an interactionist interpretation of the consciousness–brain relation. We argue that nothing (...) necessarily rules out that consciousness as something subjective may causally interact with the brain as something objective. We discuss an evolutionary argument for the theory that consciousness causally interacts with the brain, and we consider some arguments for consciousness having had a survival value. (shrink)

Natural resources are infinite. This is possible because humans can create theories whose potential goes beyond the limited imaginative capacity of the inventor. For instance, no number of people can work out all the economic potential of quantum theory. Economic Resources are created by an interaction of Karl Popper's Worlds 1, 2 and 3, the worlds of physics, psychology and the abstract products of the human mind, such as scientific theories. Knowledge such as scientific theories has unfathomable information content, is (...) universally applicable, and infinitely copyable. The point can be made with technological knowledge such as that embodied in the wheel. The theory of the wheel has un- bounded potential to be embodied in unforeseeable new technologies, is useful on the Moon as on Earth, and can be infinitely copied. Unlike a piece of land (using fixed factors), such knowledge shows increasing returns. This helps to explain Julian Simon's observation that "natural" resources are now less scarce than they used to be and why an increasing population can increase resources in the long-run. It was Simon's breakthrough to elaborate on the abstract character of "natural" resources. I further explore this abstract character and thereby explain why natural resources are infinitely expandable. Economic growth and the creation of natural resources depends on the rate of invention. F. Machlup's suggestion (Machlup 1962) that the opportunity for new inventions increases geometrically with the number of inventions at hand is acknowledged for its suggestiveness, but criticised for its conservative position. Frank Tipler's fascinating argument for indefinite economic growth (Tipler 1994), is reinforced by my argument by making a distinction between information in the engineer's sense and the infinite potential "information" in our scientific knowledge based on Popper's notion of information content.

This paper proposes that if individual X ‘inherits’ property F from individual Y, we should be leery of explanations that appeal to X’s being F. This bears on what I’ll call “emergent substance dualism”, the view that human persons or selves are metaphysically fundamental or “new kinds of things with new kinds of causal powers” even though they depend in some sense on physical particulars :5–23, 2006; Personal agency. Oxford University Press, Oxford, 2008). Two of the most prominent advocates of (...) this view, Lynne Rudder Baker and E.J. Lowe, suggest that emergent particulars have physical properties in virtue of the relations they bear to physical particulars—they ‘inherit’ their physical properties. In Sect. 1, I argue that having a property F this way is not instantiating F. In Sect. 2, I raise concerns that if emergent particulars don’t instantiate physical properties, then facts about emergent particulars don’t explain intentional actions. I suggest that emergent dualism would be more attractive if it could avoid this apparent consequence. In Sect. 3, I propose a view according to which some instances of physical properties are instantiated by both an emergent particular and its body. (shrink)

Bergson est connu pour son dualisme psycho-physique. Mais, dans sa philosophie, on trouve aussi une conception panpsychiste de la matière : l’idée que la matière inerte est douée d’un degré minime de conscience. Or, il est intéressant de remarquer que ce panpsychisme constitue en fait une théorie de la causalité, plus précisément une interprétation ontologique des notions scientifiques de « force » et de « loi de la nature ». Si cette théorie est pertinente, comme nous le pensons, elle apporte (...) un bon argument en faveur du dualisme interactionniste. Bergson is well-known for his psycho-physical dualism. But in his philosophy, we also find a panpsychist conception of matter: the idea that a minimal consciousness is linked to inert matter. Then, it is interesting to note that Bergson’s panpsychism is actually a theory of causality, more precisely an ontological interpretation of the scientific notions of ‘force’ and ‘law of nature’. If this theory is relevant, and we think it is, it provides a powerful for interactionist dualism. (shrink)

A plausible terminus for the mind-body debate begins by embracing ontological physicalism—the view that there is only one kind of substance in the concrete world, and that it is material substance. Taking mental causation seriously, this terminus also embraces conditional reductionism, the thesis that only physically reducible (i.e., functionalizable) mental properties can be causally efficacious. Intentional/cognitive properties (what David Chalmers calls “psychological” aspects of mind) are physically reducible, but qualia (“phenomenal” aspects of mind) are not. In saving the causal efficacy (...) of intentional/cognitive properties, we save cognition and agency—and even relational facts about the similarities and differences between qualia—but not the intrinsic qualities of qualia themselves, which are physically irreducible and thus causally impotent. As there seems no credible alternative to physicalism as a general worldview, and this is as much physicalism as we can have, physicalism is not the whole truth—but it is the truth near enough. -/- [1.

This paper provides evidence from the history of the natural sciences in philosophy (particularly mathematical physics, chemistry, and biology) that a “piloting” soul would have to make physical changes in human beings violating well-established physical laws.

This paper argues that nonphysical souls would violate fundamental physical laws if they were able to influence brain events. Though we have no idea how nonphysical souls might operate, we know quite a bit about how brains work, so we can consider each of the ways that an external force could interrupt brain processes enough to control one’s body. It concludes that there is no way that a nonphysical soul could interact with the brain—neither by introducing new energy into the (...) physical world, nor by borrowing existing energy from it—without apparently violating one or more basic laws of physics, such as the law of conservation of energy. And despite widespread appeals to quantum mechanics to give interactionism an air of scientific respectability, the essential randomness of quantum processes prohibits the distinctly nonrandom influence that a nonphysical soul must have on brain events in order to control the body, and quantum mechanical uncertainty is not great enough to allow neurons to fire action potentials. -/- 1.

This paper surveys the neuroscientific evidence that brain lesions and drug intoxication can not only disrupt mental functions like perception and motor control, but can also remove one’s very awareness that these functions are impaired or altered. Such deficits imply that consciousness of one’s mental faculties, no less than the faculties themselves, is a product of particular neural structures. But this is inconsistent with any view—such as the dualistic interactionism of John Eccles—that holds that the conscious self interacts with and (...) uses the brain rather than being constituted by it. -/- 1.

This paper argues that all apparently special forces characteristically reduce to a few fundamental physical forces which conserve energy and operate throughout nature. Consequently, there are probably no special mental forces originating from souls and acting upon bodies and brains in addition to the basic, energy-conserving physical forces. Moreover, physiological and biochemical research have failed to uncover any evidence of forces over and above the basic physical forces acting on living bodies. It is as if all organic processes can be (...) fully accounted for in terms of normal physical forces—that is, as if there are no souls or ethereal doubles interacting with living bodies. -/- 1.

This paper argues that since nonphysical souls lack a position in space, they cannot have the pairing relations that would allow them to interact with physical bodies. For example, if two rifles (A and B) are fired at the same time, and consequently Andy and Buddy are killed, we can only say that rifle A killed Andy while rifle B killed Buddy, rather than the other way around, if there are appropriate spatial relations (such as distance and orientation) that pair (...) Andy’s death to A’s firing, and Buddy’s death to B’s firing. But no such pairing relations are available to nonphysical minds that lack spatial positions altogether. And attributing spatial location to nonphysical souls raises more problems than it solves, such as how to find particular souls at particular locations, how souls taken to be geometric points in space could retain enough structure to have sufficient causal powers to influence bodies, and why spatial entities more robust than points shouldn’t simply be conceived of as exotic physical entities like astral bodies. -/- 1.

Because every single one of us will die, most of us would like to know what—if anything—awaits us afterward, not to mention the fate of lost loved ones. Given the nearly universal vested interest we personally have in deciding this question in favor of an afterlife, it is no surprise that the vast majority of books on the topic affirm the reality of life after death without a backward glance. But the evidence of our senses and the ever-gaining strength of (...) scientific evidence strongly suggest otherwise. -/- In The Myth of an Afterlife: The Case against Life after Death, Michael Martin and Keith Augustine collect a series of contributions that redress this imbalance in the literature by providing a strong, comprehensive, and up-to-date casebook of the chief arguments against an afterlife all in one place. Divided into four separate sections, this essay collection opens the volume with a broad overview of the issues, as contributors consider the strongest available evidence as to whether or not we survive death—in particular the biological basis of all mental states and their grounding in brain activity that ceases to function at death. Next contributors consider a host of conceptual and empirical difficulties that confront the various ways of "surviving" death—from bodiless minds to bodily resurrection to any form of posthumous survival. Then essayists turn to internal inconsistencies between traditional theological conceptions of an afterlife—Heaven, Hell, karmic rebirth—and widely held ethical principles central to the belief systems undergirding those notions. In the final section, authors offer critical evaluations of the main types of evidence for an afterlife. -/- Fully interdisciplinary, The Myth of an Afterlife: The Case against Life after Death brings together a variety of fields of research to make that case, including cognitive neuroscience, philosophy of mind, personal identity, philosophy of religion, moral philosophy, psychical research, and anomalistic psychology. As the definitive casebook of arguments against life after death, this collection is required reading for any instructor, researcher, and student in philosophy, religious studies, and theology. It is sure to raise provocative issues new to readers, regardless of background, from those who believe fervently in the reality of an afterlife to those who do not or are undecided on the matter.

Human bodies have a totally different mode of existence from those collections of mental properties (intelligence, will power, consciousness, etc.) that we call minds. They belong to the ontological category of physical substances or entities, whereas mental properties belong to the ontological category of properties or attributes, and as such can exist only so long as their physical bearers exist. Mental properties “emerge” (in a sense that makes emergence ubiquitous throughout the natural world) when the constituent parts of a biological (...) organism—especially its brain—are configured in certain sorts of ways. A view of reality that is both conceptually coherent and scientifically comprehensive makes the very idea of surviving one’s bodily death literally absurd. -/- 1.

In this article I discuss the rarely analyzed work of the Polish philosopher, sociologist, and economist Felix Młynarski. I present him against the background of contemporary intellectual currents and place him in the current of humanistic sociology, philosophy of life, and pragmatism. I also try to point out the original elements of his thought, emphasizing those which can be identified as individualism and interactionism.

A plea has been made for replacing the perspective of “symbolic interactionism” with a new interactionist's perspective—“radical interactionism.” Unlike in symbolic interactionism, where Mead's and Blumer's ideas play the most prominent roles, in radical interactionism's, Park's ideas play a more prominent role than either Mead's or Blumer's ideas. On the one hand, according to Mead, the general principle behind the organization of human group life was once dominance, but it is now “sociality.” On the other hand, according to Park, this (...) general principle is now and has always been dominance. Blumer takes a position much closer to Mead's than Park's arguing that the general principle underlying the organization of human group life is sociality. Under certain special conditions, however, it can become dominance. Although like radical interactionism, symbolic interactionism is rooted in pragmatism, unlike in radical interactionism, symbolic interactionism is still plagued with strains of utopian thought, among which the notion of sociality is the most virulent. Sociality may be the principle on which human group life is organized in heaven, but, down here on earth, it remains organized on the basis of domination. Thus, radical interactionism provides a much-needed antidote to the idealistic overtones still found in symbolic interactionism. (shrink)
