The mind-body problem arises because of our status as double agents apparently en rapport both with the mental and with the physical. We think, desire, decide, plan, suffer passions, fall into moods, are subject to sensory experiences, ostensibly perceive, intend, reason, make believe, and so on. We also move, have a certain geographical position, a certain height and weight, and we are sometimes hit or cut or burned. In other words, human beings have both minds and bodies. What (...) is the relation between these? Religion often tells us that we are really embodied souls released at death from our bodily prisons. Could this be right? (shrink)

The idea that mind and body are distinct entities that interact is often claimed to be incompatible with physics. The aim of this paper is to disprove this claim. To this end, we construct a broad mathematical framework that describes theories with mind-body interaction (MBI) as an extension of current physical theories. We employ histories theory, i.e., a formulation of physical theories in which a physical system is described in terms of (i) a set of (...) propositions about possible evolutions of the system and (ii) a probability assignment to such propositions. The notion of dynamics is incorporated into the probability rule. As this formulation emphasises logical and probabilistic concepts, it is ontologically neutral. It can be used to describe mental `degrees of freedom' in addition to physical ones. This results into a mathematical framework for psycho-physical interaction (ΨΦI formalism). Interestingly, a class of ΨΦI theories turns out to be compatible with energy conservation. (shrink)

The traditional (Leibnizian) reading of Descartes on mind-body interaction is given a more rigorous reformulation, explaining how Descartes could assert that the mind while not affecting the quantity of motion in the world could change its direction. It is shown, contrary to the trend in recent literature, that this reading has a reliable textual base, and it is argued that it attributes to Descartes a philosophical position of more substance and interest. The kind of interpretation favored (...) depends on the status that the reader attributes to the assertion of the causal closer of the material world. (shrink)

I argue that Descartes treated the action of body on mind differently from the action of mind on body, as was common in the period. Descartes explicitly denied that there is a problem for interaction but his descriptions of interaction seem to suggest that he thought there was a problem. I argue that these descriptions are motivated by a different issue, the seemingly arbitrary connections between particular physical states and the particular mental states they (...) produce. Within scholasticism there was already a (yet different) problem concerning action of body on mind. I offer a comparison between Descartes and the scholastics. (shrink)

According to Spinoza mental events and physical events are identical. What makes Spinoza's identity theory tempting is that it solves the problem of mind body interaction rather elegantly: mental events and physical events can be causally related to each other because mental events are physical events. However, Spinoza seems to deny that there is any causal interaction between mental and physical events. My aim is to show that Spinoza's apparent denial of mind body (...) class='Hi'>interaction can be reconciled with the identity theory. I argue that Spinoza had both an extensional and an intensional concept of cause and when Spinoza seems to deny mind body interaction he is having in mind the intensional concept of cause. This intensional concept of cause corresponds to that of causal explanation. I will argue that Spinoza anticipated Donald Davidson's view that even though mental events cannot be explained by referring to physical events and vice versa, mental and physical events are causally related to each other.

This article calls into question the notion that seventeenth-century authors such as Descartes and Leibniz straightforwardly conceived the mind as something "outside" nature. Descartes indeed did regard matter as distinct from mind, but the question then remains as to whether he equated the natural world, and the world of laws of nature, with the material world. Similarly, Leibniz distinguished a kingdom of final causes (pertaining to souls) and a kingdom of efficient causes (pertaining to bodies and motions), but (...) the question remains as to whether he equated nature with the second kingdom alone, or included both kingdoms within nature. Although Kant sundered Leibniz's envisioned connection between the two kingdoms, even he did not place mind fully outside nature. (shrink)

The reduction of a quantum mechanical wave function by the entry of a datum into the consciousness of an observer is used, in a semirealistic neurochemical model, to bring about excitation of a nerve cell in that observer's central nervous system. It is suggested that mind can induce muscular movements by choosing to note data originating from specialized elements of the nervous system. Only the freedom to note or not to note a relevant datum is postulated for the observer's (...) mind; the consequences of either choice are deterministic on the neural scale of events, so that quantum indeterminacy is consistent with physiological determinacy. The proposed mind-body coupling depends on the possibility of the biological evolution of a macroscopic device which has strikingly different neural correlates of its pure and mixed quantum states, respectively. An example of such a device is outlined in terms of components which are familiar from existing nervous systems. (shrink)

Based on recent findings, we propose a framework for a relationship among attention, effort and optimal performance. Optimal performance often refers to an effortless and automatic, flow-like state of performance. Mindfulness regulates the focus of attention to optimal focus on the core component of the action, avoiding too much attention that could be detrimental for elite performance. Balanced attention is a trained state that can optimize any particular attentional activity on the dual-process spectrum.

The article analyses recent English publications in Cartesian studies that deal with two problems: the problem of the intrinsic coherence of Descartes’s doctrine of the real distinction and interaction between mind and body and the problem of the consistency of this doctrine with the causal principle formulated in the Third Meditation. The principle at issue is alternatively interpreted by different Cartesian scholars either as the Hierarchy Principle, that the cause should be at least as perfect as its (...) effects, or the Containment Principle, that the cause should contain all there is in its effects. The author argues that Descartes’s claim that it is inconceivable how things of different natures can interact does not conflict with the acknowledgement of interaction between things of different natures in the case of soul and body. The case is made that Cartesian mind-body interaction can agree with both the Hierarchy Principle and the Containment Principle, because the Principle is about total and efficient cause, whereas in the interaction, mental and brain states are only partial causes. In particular, in the case of the causality in the brain-to-mind direction, the mind is conditioned by brain states to form the corresponding specific ideas on the basis of its innate general ideas of movements, forms, colours, etc. Eventually, for Descartes, the most natural way to deal with worries about the possibility of mind-brain interaction is to rely on God’s omnipotence, which certainly enables Him to arrange for such interaction.

In his "Meditations on First Philosophy", Descartes argues for there being a radical difference between mind and body. Yet, we know that mind and body interest. How is this possible? Descartes's answer tothis question is that human nature is a "substantial union" of mind and body. In this essay, Descartes's solution is explained and critically examined.

: This paper focuses on Princess Elisabeth of Bohemia's philosophical views as exhibited in her early correspondence with René Descartes. Elisabeth's criticisms of Descartes's interactionism as well as her solution to the problem of mind-body interaction are examined in detail. The aim here is to develop a richer picture of Elisabeth as a philosophical thinker and to dispel the myth that she is simply a Cartesian muse.

This innovative work takes a new approach to a fundamental dilemma of physiology, psychology, and philosophy: the subjectively perceived split between body and mind. Examining the subjective and objective aspects of movement and their relationship to our perception of mind-body separation, the author takes issue with conventional philosophical views on human duality and develops an integrative theory of interaction that suggests a basis for genuine mind-body harmony.

Descartes's notion of subjectivity changed the way characters would be written, performed by actors, and received by audiences. His coordinate system reshaped how theatrical space would be conceived and built. His theory of the passions revolutionized our understanding of the emotional exchange between spectacle and spectators. Yet theater scholars have not seen Descartes's transformational impact on theater history. Nor have philosophers looked to this history to understand his reception and impact. After Descartes, playwrights put Cartesian characters on the stage and (...) thematized their rational workings. Actors adapted their performances to account for new models of subjectivity and physiology. Critics theorized the theater's emotional and ethical benefits in Cartesian terms. Architects fostered these benefits by altering their designs. _The Mind-Body Stage_ provides a dazzlingly original picture of one of the most consequential and confusing periods in the histories of modern theater and philosophy. Interdisciplinary and comparatist in scope, it uses methodological techniques from literary study, philosophy, theater history, and performance studies and draws on scores of documents from several countries.

Spinoza breaks with Descartes’ conception of the psychophysical union and deeply changes the ontological statute of men. He considers no longer that human beings in Nature are a dominion within a dominion and share with God the privilege of being substances. In Descartes, the union of an immaterial or non‐extended substance and a material or extended substance remains beyond understanding, since the problem of whether they are able to interact arises. By identifying the mind to the idea of the (...) body, the author of the Ethics provides guidance on how to conceptualize their relationship. The psychophysical parallelism fails to explain both identity and differences in Spinoza. It presupposes homologies and one‐to‐one correspondences between ideas and things, mind and body, and leads to conceptualizing the various modal expressions according to a linearly identical model. The psychophysical union in Spinoza sounds like a duet that puts an end to duality without reducing it to a mechanical identity. (shrink)

The mind-body problem is the problem of explaining how our mental states, events and processes—like beliefs, actions and thinking—are related to the physical states, events and processes in our bodies. A question of the form, ‘how is A related to B?’ does not by itself pose a philosophical problem. To pose such a problem, there has to be something about A and B which makes the relation between them seem problematic. Many features of mind and body (...) have been cited as responsible for our sense of the problem. Here I will concentrate on two: the fact that mind and body seem to interact causally, and the distinctive features of consciousness. A long tradition in philosophy has held, with René Descartes, that the mind must be a non-bodily entity: a soul or mental substance. This thesis is called ‘substance dualism’ (or ‘Cartesian dualism’) because it says that there are two kinds of substance in the world, mental and physical or material. One reason for believing this is the belief that the soul, unlike the body, is immortal. Another reason for believing it is that we have free will, and this seems to require that the mind is a non-physical thing, since all physical things are subject to the laws of nature. (shrink)

In this paper I analyze Descartes's puzzling claim that the mind is whole in the whole body and whole in its parts, what Henry More called "holenmerism". I explain its historical background, in particular in scholasticism. I argue that like his predecessors, Descartes uses the idea for two purposes, for mind-body interaction and for the union of body and mind.

Cartesian mind body dualism and modern versions of this viewpoint posit a mind thermodynamically unrelated to the body but informationally interactive. The relation between information and entropy developed by Leon Brillouin demonstrates that any information about the state of a system has entropic consequences. It is therefore impossible to dissociate the mind's information from the body's entropy. Knowledge of that state of the system without an energetically significant measurement would lead to a violation of (...) the second law of thermodynamics. (shrink)

Mind-body parallelism is the view that mind and body stand in the same “order and connection,” as Spinoza put it, or that corresponding mental and physical states have corresponding causal explanations in terms of other mental and physical states. This dissertation investigates the nature and role of mind-body parallelism, as well as other forms of parallelism, in Spinoza’s philosophy of mind. In doing so, it also considers how Spinoza’s views relate to current discussions. (...) In present-day philosophy of mind, mind-body parallelism is almost never defended. It is seen as a historical dead-end with insurmountable problems. By contrast, I argue that parallelism powerfully responds to the post-Cartesian mind-body problem (which remains with us today) and that it points a way forward in current debates. The dissertation contains five independent chapters. After an introduction that situates parallelism in relation to both Spinoza’s time and to present discussions, Chapter 1 presents an argument for parallelism aimed at a present-day audience. Chapter 2 discusses Spinoza’s own arguments for parallelism. Both chapters help to clarify what parallelism is, in part by distinguishing between several versions of the view. Chapter 3 discusses what is often considered parallelism’s most problematic feature, its rejection of mind-body interaction. I argue that by distinguishing between the post-Cartesian context in which Spinoza wrote and present-day discussions, we can see that parallelism is compatible with mental causation. Chapters 4 and 5, finally, discuss specific ways in which parallelism is at work in Spinoza’s view of the mind. In Chapter 4, I argue that parallelism is at work in Spinoza’s interesting and distinctive positions on the nature of agency and motivation. In Chapter 5, I show the role of parallelism in his representationalist theory of consciousness. A guiding thread throughout the dissertation is that parallelism presents a distinctive and interesting way to combine realism, non-reductionism and naturalism in relation to those features of human self-understanding that seem difficult to fit into a naturalistic worldview.

The model of mind and body in Tibetan medical practice is based on Buddhist theory, and is neither dualistic in a Cartesian sense, nor monistic. Rather, it represents a genuine alternative to these positions by presenting mind/body interaction as a dynamic process that is situated within the context of the individual’s relationships with others and the environment. Due to the distinctiveness, yet interdependence, of mind and body, the physician’s task is to heal the (...) patient’s mind (blo-gso) as well as body. This in turn emphasizes the central importance of ‘compassion’ in the physician/patient relationship. This article investigates how Tibetan medical practitioners understand and enact the mind/ body and physician/patient relationships, and how this relates to theoretical explications of these relationships in Tibetan medical and Buddhist teachings. Furthermore, Tibetan medicine provides an interesting model for comparison with embodied theories of cognition, which see consciousness, the body and its environment as integral parts of a complex, dynamical cognitive system.

What is the relationship between our perceptions and reality? What is the relationship between the mind and the body? These are questions with which philosophers have grappled for centuries, and they are topics of considerable contemporary debate as well. Hilary Putnam has approached the divisions between perception and reality and between mind and body with great creativity throughout his career. Now, in _The Threefold Cord: Mind, Body, and World,_ he expounds upon these issues, elucidating (...) both the strengths and weaknesses of current schools of thought. With his characteristic wit and acuity, Putnam offers refreshing solutions to some of philosophy's most vexing problems. Putnam first examines the problem of realism: is objective truth possible? He acknowledges the deep impasse between empirical and idealist approaches to this question, critiquing them both, however, by highlighting the false assumption they share, that we cannot perceive the world directly. Drawing on the work of J. L. Austin and William James, Putnam develops a subtle and creative alternative, which he calls "natural realism." The second part of the book explores the mind-body question: is the mind independent of our interactions with the physical world? Again, Putnam critically assesses two sharply antithetical contemporary approaches and finds them both lacking. _The Threefold Cord_ shows the entire mind-body debate to be miscast and draws on the later work of Wittgenstein, once more advancing original views on perception and thought and their relationship with both the body and the external world. Finally, Putnam takes up two related problems--the role of causality in human behavior and whether or not thoughts and sensations have an "existence" all their own. With Putnam's lucid prose and insightful examples, _The Threefold Cord_ loosens the Gordian knots into which philosophy has bound itself over the issue of epistemology. (shrink)

Prevailing theories of consciousness may be characterized as either a physicalist view of mind with material building blocks that grow in complexity unto an emergent conscious experience, or as a dualistic model in which mind-body interaction is taken as the interface of conscious intent and unconscious bodily processing. Roger Penrose supports a model of consciousness that goes beyond dualism by adding a third domain [19]. The Three World model describes interconnected yet independent aspects of consciousness: Physical, (...) Mental & Platonic. These three worlds are grounded in the three axioms of quantum mechanics: measurement, superposition and entanglement. The Mental World corresponds to the superposition principle in which all possible future realities are superposed as potentials before a choice is made. The superposition is analogous to the choices we make everyday. In the Physical World, the measurement principles states that the quantum system must collapse the superposed possibilities into a single actuality. The most peculiar phenomenon in quantum mechanics is entanglement. Quantum systems may be entangled in a timeless and spaceless way such that they will still be connected despite separation in space or time. The Platonic World is akin to entanglement, because mathematics and conceptual forms are unchanging regardless of space or time. Finally, a new model called Fractal Trialism is proposed which describes how there is a nested trialism within each of the three worlds in order to elaborate their interconnectedness. This model describes digital computers, quantum computers and shared experience.

The mind-body problem is analyzed in a physicalist perspective. By combining the concepts of emergence and algorithmic information theory in a thought experiment employing a basic nonlinear process, it is argued that epistemically strongly emergent properties may develop in a physical system. A comparison with the significantly more complex neural network of the brain shows that also consciousness is epistemically emergent in a strong sense. Thus reductionist understanding of consciousness appears not possible; the mind-body problem does (...) not have a reductionist solution. The ontologically emergent character of consciousness is then identified from a combinatorial analysis relating to system limits set by quantum mechanics, implying that consciousness is fundamentally irreducible to low-level phenomena. In the perspective of a modified definition of free will, the character of the physical interactions of the brain's neural system is subsequently studied. As an ontologically open system, it is asserted that its future states are undeterminable in principle. We argue that this leads to freedom of the will. (shrink)

theories. What was Freud thinking, when, and why and what were the major influences which shaped his ideas? We follow the inner movement of his theory construction, its meaning and coherence, as well as his conceptual logic and personal directions concerning his evolving views of the reciprocal interactions between mind and body, the motivational force of instinctual drives, and the dominant role of sexuality rooted in evolutionary biology in human development, behaviour, and the creation of neurotic disturbances. We (...) follow Freud's construction and sequential reconstructions of his theoretical models concerning the nature, dynamics, and principles of unconscious mental functioning, including his changing concepts on the nature and purpose of dreams. We trace his changing views on the role of deferred action of early childhood experiences and the determining role of unconscious fantasy, psychic reality, in the formation of adult character structure and neuroses. Through such historical analysis this book provides grounding for a meaningful understanding of Freud's familiar concepts: id, ego, superego, and the Oedipus complex. We explore what these concepts meant to Freud, why he conceived them, and what functions they served in his theory of mind. This is the perfect book for students and trainees wanting to learn more about the development of Freud's ideas, as well as for established psychoanalysts and psychotherapists interested in expanding their knowledge of Freud's theories.

One of the most influential thinkers of the 20th century, Sir Karl Popper here examines the problems connected with human freedom, creativity, rationality and the relationship between human beings and their actions. In this illuminating series of papers, Popper suggests a theory of mind-body interaction that relates to evolutionary emergence, human language and what he calls "the three worlds." Rene; Descartes first posited the existence of two worlds--the world of physical bodies and the world of mental states. (...) Popper argues for the existence of "world 3" which comprises the products of our human minds. He examines the interaction between mental states--hopes, needs, plans, ideologies or hypotheses--and the physical states of our brain. Popper forcefully argues against the materialism forwarded by many philosophers which denies the existence of mental states. Instead, he demonstrates that the problem of the interaction between mental and physical states remains unresolved. Knowledge and the Body-Mind Problem is based on Popper's never-before published lectures at Emory University in 1969. Popper has extensively revised the lectures but has retained their accessible format. He has also incorporated some of the discussions which followed the lectures, providing an engaging exchange between the philosopher and his audience. (shrink)

Eric Voegelin’s writings on the historical development of the concept of race in the early 1930s are important to philosophy today in part because they provide a model upon which scholars can further integrate modern philosophy with the critical philosophy of race. In constructing his history, Voegelin’s methodological orientation depends on the centrality of both Kant’s work and the problem of the mind–body union to the concept of race. This essay asks how one might hold these premises if (...) Kant seems to reject the dominant approach to the mind–body union in the mid-eighteenth century, physical influx, and then go on to publish several essays on race that do not thematize that doctrine in any way. I argue that Kant’s racial union of mind and body cannot be understood as an interaction in space, as his contemporaries had presumed. Rather, the union must be approached as a repetition in time. In this way, Kant’s four racial categories are not merely a part of the mind–body problem, but instead each is a veritable mind–body union. This permits the conclusion that ‘race’, as Kant understood it, is a viable solution to the mind–body problem. (shrink)

The mind-body problem is intuitively familiar, as mental and physical entities mysteriously interact. However, difficulties arise when intertwining concepts of the self with mental and physical traits. To avoid confusion, I propose instead focusing on three categories, with the mental matching the mind and physical the body with respect to raw inputs and outputs. The third category, the self, will experience and measure the others. With this new classification, we can see difficulties clearly, specifically five questions (...) covering interaction and correlation. We break down the problem using both existing theories and a hypercube topology representing the solution. We show any satisfactory theory must explain both spatial interaction and content correlation, and that we cannot escape our topology, whatever our preferred fundamental substance and mind-body movement permutation. We conclude by looking outside the hypercube, noting how solutions such as existential monism, priority monism, and will-based cosmic-idealism avoid the dangers involved. (shrink)

In this paper, I explore anomalous dualism about consciousness, a view that has not previously been explored in any detail. We can classify theories of consciousness along two dimensions: first, a theory might be physicalist or dualist; second, a theory might endorse any of the three following views regarding causal relations between phenomenal properties (properties that characterize states of our consciousness) and physical properties: nomism (the two kinds of property interact through deterministic laws), acausalism (they do not causally interact), and (...) anomalism (they interact but not through deterministic laws). I suggest that a kind of anomalous dualism, nonreductive anomalous panpsychism, promises to offer the best overall answer to two pressing issues for dualist views, the problem of mental causation and the mapping problem (the problem of predicting mind-body associations).

Major depression is a disorder of the mind caused by dysfunction of both the body and the brain. Because it is a psychiatric illness and psychiatry is a branch of medicine, the question of how mind and body interact in depression should be treated as a medical rather than metaphysical mind-body problem. The relation between mind and body as it pertains to this illness should be construed in teleological rather than causal terms. (...) Mental states like beliefs and emotions serve an adaptive purpose by constraining the physiologic systems involved in the body's stress response, thus preserving homeostasis and protecting us from various disorders. Depression results when the mind fails it its constraining role. (shrink)

John Harfouch’s new book, Another Mind-Body Problem: A History of Racial Non-Being, argues that Immanuel Kant, widely considered the most influential philosopher of the modern period, is the first to claim the lives of non-white people are redundant and worthless. He articulates this through a metaphysics of minds and bodies that ultimately transforms the meaning of philosophy’s mind-body problem. A mind-body problem in the Kantian tradition is not a problem of how minds and bodies (...) interact or brain states give rise to consciousness. Rather, the problem is one of how a union of minds and bodies regenerates without reason, or of how a oneness repeats its own nothingness. Born without reason, the non-white world is a kind of human waste that can be eliminated without consequence. Accordingly, a properly understood history of the mind-body problem reckons with the problem of genocidal violence. Following this transformation of the mind-body problem from the late sixteenth century through Descartes’s writings and into the eighteenth century, Harfouch argues in Another Mind-Body Problem that philosophy has not understood its most canonical and long-standing problem and must now change who is hired and funded to solve it.

Descartes entitled the Sixth Meditation "The existence of material things, and the real distinction between mind and body." But these topics take up only two paragraphs, about one-third of the way into the Sixth Meditation (which is the longest of the six). The other topics in the Meditation partly pertain to the cognitive faculties that a seeker after knowledge must employ: senses, imagination, and intellect. They also concern the mind–body relation: not only is it to be (...) shown that mind and body are distinct, but also that they are “closely joined” together. The joining of mind to body contributes to explanations of the cognitive faculties, for such a joining is, in Descartes’ view, necessary for the operation of sense and imagination, whereas the exercise of the intellect in the pursuit of metaphysical results -- as in his argument for mind–body distinctness -- takes place without the mind interacting with the body. But this still doesn't account for the most sustained discussion in the Sixth Meditation, which concerns the role of the senses in informing us about the world around us. While the trustworthiness of the senses has been under suspicion up to this point in the Meditations, now the senses are rehabilitated. They can serve to acquaint us with the world of bodies, for the purposes of empirical investigation serving natural philosophy but, more usually, for the practical purpose of informing us of potential benefits and harms in our immediate environment. In this regard, Descartes considers the ways in the senses might be subject to local errors or might, if used inappropriately, draw us into systematic error. But the previous results of the Meditations now offer the means for avoiding such systematic error, and the reflections of the Sixth Meditation can guide us toward practical uses of the senses in ways that reduce error. In the end, the senses are found to be trustworthy for the guidance of action, and this trustworthiness extends even to a qualitative experience such as color, which helps us to discriminate among the bodies that we see.

A Bell-type strategy of decision for the long-standing question of the nature of psychophysical correlations has been previously presented in a recent article published in Mind and Matter. This strategy of decision is here applied to experimental data on psychophysiological correlations, namely, correlations between cardiovascular and emotional variables that have been reported in several independent publications. This statistical analysis shows that a substantial majority of these correlations cannot be interpreted as an exchange of signals or a mere “interaction”, (...) whatever its form, but that these correlations could a priori be explained classically, as the result of a common preparation during the evolution process. A discussion on the scope and the limitations of this result will then be provided. In particular, alternative explanations of the psychophysical correlations that do not appeal to a notion of signalling will be discussed. (shrink)
