In many fields in the life sciences investigators refer to downward or top-down causal effects. Craver and Bechtel defended the view that such cases should be understood in terms of a constitution relation between levels in a mechanism and causation as solely an intra-level relation. Craver and Bechtel, however, provided insufficient specification as to when entities constitute a higher-level mechanism. In this paper I appeal to graph-theoretic representations of networks that are now widely employed in systems biology and (...) neuroscience to identify mechanisms with the modules that exhibit high clustering. As a result of the interconnections of nodes in these modules/mechanisms, they often exhibit complex dynamic behaviors that constrain how the individual components respond to external inputs, an important feature of cases viewed as involving top-down causation.

This book presents the latest research, conducted by leading philosophers and scientists from various fields, on the topic of top-down causation. The chapters combine to form a unique, interdisciplinary perspective, drawing upon George Ellis's extensive research and novel perspectives on topics including downwards causation, weak and strong emergence, mental causation, biological relativity, effective field theory and levels in nature. The collection also serves as a Festschrift in honour of George Ellis' 80th birthday. The extensive and interdisciplinary (...) scope of this book makes it vital reading for anyone interested in the work of George Ellis and current research on the topics of causation and emergence.

We argue that intelligible appeals to interlevel causes (top-down and bottom-up) can be understood, without remainder, as appeals to mechanistically mediated effects. Mechanistically mediated effects are hybrids of causal and constitutive relations, where the causal relations are exclusively intralevel. The idea of causation would have to stretch to the breaking point to accommodate interlevel causes. The notion of a mechanistically mediated effect is preferable because it can do all of the required work without appealing to mysterious interlevel causes. (...) When interlevel causes can be translated into mechanistically mediated effects, the posited relationship is intelligible and should raise no special philosophical objections. When they cannot, they are suspect. (shrink)

I criticize the view that top-down causation is a proper model for depicting and justifying belief in mental causation. When properly interpreted, I believe that there are no clear examples of top-down causation, and there is a persuasive case against it. In order to defend these claims, I, first, clarify three preliminary considerations; second, undermine alleged examples of top-down causation; third, present a case for why there is no top-down mental causation; (...) fourth, explain an important option for moving forward in preserving what we all know to be the case—that mental causation is real. (shrink)

Top-down causation is often taken to be a metaphysically suspicious type of causation that is found in a few complex systems, such as in human mind-body relations. However, as Ellis and others have shown, top-down causation is ubiquitous in physics as well as in biology. Top-down causation occurs whenever specific dynamic behaviors are realized or selected among a broader set of possible lower-level states. Thus understood, the occurrence of dynamic and structural patterns in (...) physical and biological systems presents a problem for reductionist positions. We illustrate with examples of universality and functional equivalence classes how higher-level behaviors can be multiple realized by distinct lower-level systems or states. Multiple realizability in both contexts entails what Ellis calls “causal slack” between levels, or what others understand as relative explanatory autonomy. To clarify these notions further, we examine procedures for upscaling in multi-scale modeling. We argue that simple averaging strategies for upscaling only work for simplistic homogenous systems, because of the scale-dependency of characteristic behaviors in multi-scale systems. We suggest that this interpretation has implications for what Ellis calls mechanical top-down causation, as it presents a stronger challenge to reductionism than typically assumed. (shrink)

Physics underlies all complexity, including our own existence: how is this possible? How can our own lives emerge from interactions of electrons, protons, and neutrons? This book considers the interaction of physical and non-physical causation in complex systems such as living beings, and in particular in the human brain, relating this to the emergence of higher levels of complexity with real causal powers. In particular it explores the idea of top-down causation, which is the key effect allowing (...) the emergence of true complexity and also enables the causal efficacy of non-physical entities, including the value of money, social conventions, and ethical choices.

In this response, George Ellis comments on the publications of Part IV. He responds first to James Woodward, Richard Healey, Jan Voosholz, Simon Friederich and Sach Mukherjee, before outlining his thoughts on Max Kistler’s piece.

In this paper, we explore the architecture of downward causation on the basis of three central cases. We set out by answering the question of how top-down causation is possible in the universe. The universe is not causally closed, because of irreducible randomness at the quantum level. What is more, contextual effects can already be observed at the level of quantum physics, where higher levels can modify the nature of lower-level elements by changing their context, or even (...) creating them. As one moves up through higher levels, contextual effects on lower levels occur on various scales within nature, which is crucial in biology in general and the brain in particular. We then argue that there are important logical downward causes.objects have causal effects on material-energetic systems. It can be shown that abstract objects have measurable effects on lower levels, which needs to be accounted for by successful explanations of real phenomena such as intentional action. Intentional action has the form of deductive causation from logical structures to human agency. Without this assumption, we would not be warranted in believing that our physical theories latch onto a universe that is essentially the way we discover it to be. Denying top-down causation on account of the idea that the universe permits only bottom-up constitution of wholes from lower-level elements leads to undermining the very possibility of knowledge and science. Thus, it can be rejected as a global form of explanation. We sketch a model for mind-body interaction according to which the various levels of a human organism together enable the emergence of mental top-down effects. They are necessary conditions for the emergence of human mindedness. Once it is clear that downward causation is a widespread natural phenomenon, the apparent mystery of mental causation is, in principle, solved. (shrink)

Dual-attribute theories are alleged to face a problem with mental causation which commits them to either epiphenomenalism or overdetermination – neither of which is attractive. The problem, however, is predicated on assumptions about psychophysical relations that dual-attribute theorists are not obliged to accept. I explore one way they can solve the problem by rejecting those assumptions.

Though predictive processing approaches to the mind were originally applied to exteroceptive perception, i.e., vision and action, recent work has started to explore the role of interoceptive perception, i.e., emotion and affect. This article builds on this work by extending PP beyond emotion to the construction of emotional dispositions. I employ principles from dynamical systems theory and PP to provide a model of how dispositional anger can develop in response to early experiences of psychosocial stress. The model is then deployed (...) to explain the established link between psychosocial stress in early life and the appearance of certain organic disease phenotypes in later life. This phenomenon can appear mysterious when viewed through the standard biomedical explanatory lens, which has difficulty accounting for the causal influence of subjective perceptions and evaluations of the social and material environment on the development of organic disease processes. The model provided presents such cases as instances of developmental mismatch. They occur when an organism develops an emotional disposition that leads them to make habitually-biased appraisals of what the social environment affords. The model provides a novel explanation of certain organic disease phenotypes with top-down and developmental causes, and demystifies one class of cases involving apparently spooky ‘mind-to-matter’ causation.

Resumo Este artigo centra-se na relevância metodológica da causalidade de tipo top-down. É fornecida uma análise do alcance e dos limites da metodologia reducionista tradicional. São distinguidos cinco tipos de concepções reducionistas: um requisito metodológico geral, o conselho pragmático de se seguir metodologias bem estabelecidas, um reducionismo inter-teórico, uma forma intra-teórica e, finalmente, um reducionismo ontológico. Subsequentemente, salienta-se a existência de domínios onde uma abordagem diferente, mas complementar, centrada em explicações etiológicas de tipo top-down, pode ser útil para (...) melhorar o nosso conhecimento dos organismos. Também é evidenciado que a causalidade de tipo top-down não pode ser separada de mecanismos de controle exibindo, numa estrutura biológica, a capacidade básica da homeostase. Palavras-chave : causalidade de tipo top-down, controlo de informação, explicação etiológica, explicação genética, reducionismoThis paper focuses on the methodological relevance of top-down causation. An analysis of the scope and limits of the traditional reductionist methodology is provided. Five kinds of reductionist conceptions are distinguished: a general methodological requirement, the pragmatic advice to follow well-established methodologies, an inter-theoretic reductionism, an intra-theoretic form and finally an ontological reductionism. Thereafter, it is pointed out that there are domains where a different but complementary approach centred on top-down etiological explanations could be helpful for improving our knowledge of organisms. It is also shown that top-down causation cannot be separated from control-mechanisms displaying, in a biological framework, the basic ability to keep homeostasis. Keywords : etiological explanation, genetical explanation, information control, reductionism, top-down causation. (shrink)

Experimental investigation of mechanisms seems to make use of causal relations that cut across levels of composition. In bottom-up experiments, one intervenes on parts of a mechanism to observe the whole; in top-down experiments, one intervenes on the whole mechanism to observe certain parts of it. It is controversial whether such experiments really make use of interlevel causation, and indeed whether the idea of causation across levels is even conceptually coherent. Craver and Bechtel have suggested that interlevel (...) causal claims can be analysed in a causal and a non-causal component. I accept this idea but argue that their account should be modified so as to account of cases of apparent downward causation. First, constitution must be distinguished from identity; second, the analysis of downward causation requires the concept of a partial constraint. An analysis along these lines shows that the possibility of downward causation is not refuted by Kim's argument according to which it is incompatible with the completeness of physics. (shrink)

I have two main aims. The first is general, and more philosophical. The second is specific, and more closely related to physics. The first aim is to state my general views about laws and causation at different ”levels’. The main task is to understand how the higher levels sustain notions of law and causation that ”ride free’ of reductions to the lower level or levels. I endeavour to relate my views to those of other symposiasts. The second aim (...) is to give a framework for describing dynamics at different levels, emphasizing how the various levels’ dynamics can mesh or fail to mesh. This framework is essentially that of elementary dynamical systems theory. The main idea will be, for simplicity, to work with just two levels, dubbed ”micro’ and ”macro’, which are related by coarse-graining. I use this framework to describe, in part, the first four of Ellis’ five types of top-down causation. (shrink)

The ubiquity of top-down causal explanations within and across the sciences is prima facie evidence for the existence of top-down causation. Much debate has been focused on whether top-down causation is coherent or in conflict with reductionism. Less attention has been given to the question of whether these representations of hierarchical relations pick out a single, common hierarchy. A negative answer to this question undermines a commonplace view that the world is divided into stratified ‘levels’ (...) of organization and suggests that attributions of causal responsibility in different hierarchical representations may not have a meaningful basis for comparison. Representations used in top-down and bottom-up explanations are primarily ‘local’ and tied to distinct domains of science, illustrated here by protein structure and folding. This locality suggests that no single metaphysical account of hierarchy for causal relations to obtain within emerges from the epistemology of scientific explanation. Instead, a pluralist perspective is recommended—many different kinds of top-down causation (explanation) can exist alongside many different kinds of bottom-up causation (explanation). Pluralism makes plausible why different senses of top-down causation can be coherent and not in conflict with reductionism, thereby illustrating a productive interface between philosophical analysis and scientific inquiry.

Accounts of mechanistic explanation have emphasized the importance of looking down—decomposing a mechanism into its parts and operations. Using research on visual processing as an exemplar, I illustrate how productive such research has been. But once multiple components of a mechanism have been identified, researchers also need to figure out how it is organized—they must look around and determine how to recompose the mechanism. Although researchers often begin by trying to recompose the mechanism in terms of sequential operations, they (...) frequently find that the components of a mechanism interact in complex ways involving positive and negative feedback and that the organization often exhibits highly interactive local networks linked by a few long-range connections (small-worlds organization) and power law distributions of connections. The mechanisms are themselves active systems that are perturbed by inputs but not set in motion by them. Researchers also need to look up —situate a mechanism in its context, which may be a larger mechanism that modulates its behavior. When looking down is combined with looking around and up, mechanistic research results in an integrated, multi-level perspective. (shrink)

The concept of God's acting in the world has been seen to be problematic in light of the claims of scientific knowledge that the regularity of a law like universe rules out divine action. There are resources in both scientific knowledge and religion that can render meaningful and credible divine action. The new physics, chaos theory, cognitive psychology, and the concept of top‐down causation are used to understand how God acts in the world. God's action is not an (...) intervention, but is understood on the model of how the mind influences the brain in a downward causative manner. Suggestions for imagining God's actions are discussed.

In this article we argue that the classical—linear and bottom-up directed—models of causation in biology, and the ‘‘proximate/ultimate’’ dichotomy, are inappropriate to capture the complexity inherent to biological processes. We introduce a new notion of ‘‘multilevel causation’’ where old dichotomies such as proximate/ultimate and bottom-up/ top-down are reinterpreted within a multilevel, web-like, approach. In briefly reviewing some recent work on complexity, EvoDevo, carcinogenesis, autocatalysis, comparative genomics, animal regeneration, phenotypic plasticity, and niche construction, we will argue that such (...) reinterpretation is a necessary step for the advancement of the ‘‘Extended Synthesis.’’.

In this paper, I discuss two aspects of top-down causation in George Ellis’s compelling account of this complex concept. I first examine whether mathematical structures can enter into any causal relations, and argue that it is unclear that they can. I highlight instead the role played by the interpretation of mathematical theories in the context of applied mathematics. Second, I consider the role played by top-down causation in measurement, especially in quantum mechanics but also elsewhere, and (...) identify the importance of the observer in this context. I am in large agreement with Ellis’s overall message, but we may understand certain details a bit differently. I articulate the message within a broadly empiricist setting. (shrink)

In my article I evaluate Searle's account of mental causation, in particular his account of the causal efficacy of unconscious intentional states. I argue that top-down causation and overdetermination are unsolved problems in Searle's philosophy of mind, despite his assurances to the contrary. I also argue that there are conflicting claims involved in his account of mental causation and his account of the unconscious. As a result, it becomes impossible to understand how unconscious intentional states can (...) be causally efficacious. My conclusion will be that if Searle's conception of unconscious intentionality is to play a genuine role in the causal explanation of human action, it needs to be rethought. (shrink)

I offer a pragmatist understanding of causation, laws and explanation that traces the features of these notions to their functions in our practical as well as theoretical projects. Laws derive their importance from their epistemic and methodological functions, while the primary role of causal concepts is in guiding action. Contemporary interventionist accounts of causation and causal modeling appeal to and clarify this practical role while downplaying the causal significance of laws. They also explain how causation in one (...) science or at one level of complexity may be either related to or independent of causation in other sciences or at other levels. In this way they can demystify the notion of top-down causation by showing how, and when, it is possible. (shrink)

Dynamical systems promise to elucidate a notion of top–down causation without violating the causal closure of physical events. This approach is particularly useful for the problem of mental causation. Since dynamical systems seek out, appropriate, and replace physical substrata needed to continue their structural pattern, the system is autonomous with respect to its components, yet the components constitute closed causal chains. But how can systems have causal power over their substrates, if each component is sufficiently caused by (...) other components? Suppose every causal relation requires background conditions, without which it is insufficient. The dynamical system is structured with a tendency to change background conditions for causal relations anytime needed substrates for the pattern's maintenance are missing; under the changed background conditions, alternative causal relations become sufficient to maintain the pattern. The system controls the background conditions under which one or another causal relation can subserve the system's overall pattern, while the components remain causally closed under their given background conditions.

Complexity–nonlinear dynamics for my purposes in this essay–is rich with metaphysical and epistemological implications but is only recently receiving sustained philosophical analysis. I will explore some of the subtleties of causation and constraint in Rayleigh-Bénard convection as an example of a complex phenomenon, and extract some lessons for further philosophical reflection on top-down constraint and causation particularly with respect to causal foundationalism.

Framing systematics as a field consistent with scientific inquiry entails that inferences of phylogenetic hypotheses have the goal of producing accounts of past causal events that explain differentially shared characters among organisms. Linking observations of characters to inferences occurs by way of why-questions implied by data matrices. Because of their form, why-questions require the use of common-cause theories. Such theories in phylogenetic inferences include natural selection and genetic drift. Selection or drift can explain ‘morphological’ characters but selection cannot be causally (...) applied to sequences since fitness differences cannot be directly associated with individual nucleotides or amino acids. The relation of selection to sequence data is by way of downward or top-down causation from those phenotypes upon which selection occurs. The application of phylogenetic inference to explain sequence data is thus restricted to instances where drift is the relevant theory; those nucleotides or amino acids that can be explained via downward causation are precluded from inclusion in the data matrix. The restrictions on the inclusion of sequence data in phylogenetic inferences equally apply to species hypotheses, precluding the more restrictive approach known as DNA barcoding. Not being able to discern drift and selection as relevant causal mechanisms can severely constrain the inclusion and explanations of sequence data. Implications of such exclusion are discussed in relation to the requirement of total evidence. (shrink)

In Causation & Laws of Nature in Early Modern Philosophy, Walter Ott offers us a fascinating account of the development of theories of causation and laws of nature in the early modern period. The central theme of the book traces the development of two approaches to causation in the period: the “top-down analysis” and the “bottom-up analysis.” According to the former approach, the laws of nature are not “fixed by the natures of the objects they govern.” (...) Rather, the content of the laws of nature depends solely on God and the contents of God’s will . The latter approach, on the other hand, holds that the “course of nature is fixed by the properties of created beings” . On this approach, a fire’s burning, for example, is a function of the powers of the fire and the wood, not the will of God. Ott treats Descartes and Malebranche as paradigm cases of the top-down approach, and Locke and Pierre-Sylvain Regis as examples of the bottom-up approach, with Boyle displaying hints of both approaches.Central to Ott’s treatment is situating the early modern debate in the context of the dominant Aristotelian Scholastic position on causation . Ott argues that the Scholastic position was, among other things, a bottom-up view that treated true. (shrink)

In temporal binding, the temporal interval between one event and another, occurring some time later, is subjectively compressed. We discuss two ways in which temporal binding has been conceptualized. In studies showing temporal binding between a voluntary action and its causal consequences, such binding is typically interpreted as providing a measure of an implicit or pre-reflective “sense of agency”. However, temporal binding has also been observed in contexts not involving voluntary action, but only the passive observation of a cause-effect sequence. (...) In those contexts, it has been interpreted as a top-down effect on perception reflecting a belief in causality. These two views need not be in conflict with one another, if one thinks of them as concerning two separate mechanisms through which temporal binding can occur. In this paper, we explore an alternative possibility: that there is a unitary way of explaining temporal binding both within and outside the context of voluntary action as a top-down effect on perception reflecting a belief in causality. Any such explanation needs to account for ways in which agency, and factors connected with agency, have been shown to affect the strength of temporal binding. We show that principles of causal inference and causal selection already familiar from the literature on causal learning have the potential to explain why the strength of people’s causal beliefs can be affected by the extent to which they are themselves actively involved in bringing about events, thus in turn affecting binding.

My purpose in this essay is to provide a critical survey of arguments within recent analytic philosophy regarding the so-called “mind-body problem” with a particular view toward the relationship between these arguments and the philosophy of A.N. Whitehead (and Charles Hartshorne’s closely related views).1In course, I shall argue that Whitehead’s panexperientialist physicalism avoids paradoxes and difficulties of both materialist-physicalism and Cartesian dualismas advocated by a variety of analytic philosophers. However, and I believe that this point is not often sufficiently recognized, (...) analytic philosophy of mind is no monolith, and there are those who have found some form of panexperientialism to be attractive enough to merit serious consideration or even full-fledgedacceptance (David Chalmers, Thomas Nagel, Ralph Pred, William Seager, and Galen Strawson among them). A critical discussion of such thinkers should beincluded in any adequate survey of the relation between process panexperientialism and the analytic tradition. Moreover, the revisionary strain of the analyticaltradition which looks to natural science for its construction of worldviews (Broad, Russell, Bunge, Carnap, Quine, etc.) would move us in the direction of examining arguments concerning Whitehead’s view and contemporary empirical scientific considerations. (For a discussion of the basic nature of analytic philosophy and the descriptive and revisionary approaches contained within it, see my Process and Analysis, 5-9, 12-13, 57; and McHenry.) Here I shall argue that Whiteheadian panexperientialism very naturally accommodates important aspects of quantum theory, including the top-down causation involved in neuroplastic phenomena under a quantum mechanical interpretation of brain processes and in so-called Quantum Zeno Effect. The overall picture which emerges is that Whitehead’s position is (at the very least) a strongly plausible alternative in philosophy of mind.While I must confess that this essay can only represent the merest sketch—indeed an adequate treatment of the richly complex interpretive, comparative, and substantive philosophical issues here requires at the very least a monograph—I nonetheless hope to present a coherent and useful précis of major arguments and comparative conceptual relationships, especially for the reader who may not be readily familiar with this terrain. I thus hope that this essay will serve as a short expository and critical introduction to the interface between process and analytic philosophy of mind, and a presentation of the several theoretical advantages gained by listening to Whitehead’s theory as it connects with concerns of analytic philosophers.I shall proceed by first working though the main outlines of John Searle’s important and widely reaching “The Recent History of Materialism,” an essay which exposes critical flaws in a variety of materialist theories in ways which Whiteheadians should find especially fitting and congenial. I shall then examine defenses of dualism and the relation of Whitehead to such defenses, followed by a separate section on Chalmers, Nagel, and Pred. I will then consider a number ofimportant objections to process panexperientialism, including objections arising from the work of Jaegwon Kim and John Searle. I close with a discussion of thementioned empirical scientific arguments. (shrink)

After a concise description of issues concerning the causal and the deductive-nomological models of explanation, the flaws in the alternative view centred on relevance-to-context are examined. The paper argues for the need of a wider spectrum of options which takes into account both the Local/Global and the Internal/External aspects in order to determine the sense and the adequacy of any explanation. As a test for this argument, some specific problems are considered about the range of causal bonds, the admission of (...) top-down causation, the appeal to emergence, the shift from explanation to explainability, the equivalence classes referred to as “cause” and “effect”. Finally, the paper deals with the comparison between inequivalent explanations and lists three remaining issues to complete the picture. (shrink)

Which way does causation proceed? The pattern in the material world seems to be upward: particles to molecules to organisms to brains to mental processes. In contrast, the principles of quantum mechanics allow us to see a pattern of downward causation. These new ideas describe sets of multiple levels in which each level influences the levels below it through generation and selection. Top-down causation makes exciting sense of the world: we can find analogies in psychology, in (...) the formation of our minds, in locating the source of consciousness, and even in the possible logic of belief in God.

This article considers the kind of knowledge that is constituted through embodied sensory perception and makes the case for a form of knowledge that is embodied, relational, and potentially transformational. Such knowledge is encountered through our physiological senses and cultivated by reestablishing connections to our bodies. The discussion starts by exploring the literature on sensory perception and interoception and moves on to the role of human agency, which is implicit in the idea of top‐down causation. It is argued (...) that this process can be explained by a top‐down predictive model within which a sense of greater interoceptive accuracy may be cultivated while reducing interoceptive perturbation. The roles of active and perceptual inference are discussed with regard to the regulatory opportunities that these types of attention yield. By being more interoceptively aware, through a practice of contemplation, it is argued, we open ourselves to an encounter with divine presence that is immanent in the world around us. (shrink)

Physics and chemistry underlie the nature of all the world around us, including human brains. Consequently some suggest that in causal terms, physics is all there is. However, we live in an environment dominated by objects embodying the outcomes of intentional design (buildings, computers, teaspoons). The present day subject of physics has nothing to say about the intentionality resulting in existence of such objects, even though this intentionality is clearly causally effective. This paper examines the claim that the underlying physics (...) uniquely causally determines what happens, even though we cannot predict the outcome. It suggests that what occurs is the contextual emergence of complexity: the higher levels in the hierarchy of complexity have autonomous causal powers, functionally independent of lower level processes. This is possible because top-down causation takes place as well as bottom-up action, with higher level contexts determining the outcome of lower level functioning and even modifying the nature of lower level constituents. Stored information plays a key role, resulting in non-linear dynamics that is non-local in space and time. Brain functioning is causally affected by abstractions such as the value of money and the theory of the laser. These are realised as brain states in individuals, but are not equivalent to them. Consequently physics per se cannot causally determine the outcome of human creativity, rather it creates the possibility space allowing human intelligence to function autonomously. The challenge to physics is to develop a realistic description of causality in truly complex hierarchical structures, with top-down causation and memory effects allowing autonomous higher levels of order to emerge with genuine causal powers.

This paper defends the notion of downward causation. I will seek to elucidate this notion, explain why it is a useful way of thinking, and respond to criticisms attacking its intelligibility. My account of downward causation will be in many respects similar to the account recently advanced by Ellis. The overall framework I will adopt is the interventionist treatment of causation I have defended elsewhere: X causes Y when Y changes under a suitable manipulation of X. When (...) X is at a higher “level” than Y this allows for the possibility of downward causation from X to Y. True claims of downward causation must meet certain additional conditions, some of which have already been discussed by Ellis. These include the condition that X must have a homogenous effect on Y in the sense that the effect of X on Y must be the same regardless of how X is “realized” at lower levels. In addition, the most plausible examples of downward causation will involve causes X, that in a sense that I will try to specify, are capable of being manipulated by macro-level interventions that have a coordinated or organized impact on them, as when one manipulates the temperature of a gas by placing it in a heat bath.Three common criticisms of the notion of downward causation that I will consider are: the claim that this involves a whole acting downward on its parts which is an objectionable idea because wholes and parts are not sufficiently distinct to stand in causal relationships, that downward causation commits us to the existence of causal cycles in which X causes Y which in turn causes X and that the asymmetric nature of the causal relation rules out such cycles, and causal exclusion type worries, according to which all of the causal action occurs among “low level” variables, so that upper level variables are deprived of causal efficacy. In response I will argue that plausible examples of downward causation in the scientific literature do not involve whole to part causation, there is nothing wrong with causal cycles, which are common in, for example, biological contexts, exclusion type worries do not arise within the interventionist framework that I favor.

This thesis develops a disjunctivist approach to action as an alternative to the standard causal theory, or 'causalism'. The standard theory promotes a concept of action as constituted by a bodily event joined to certain mental conditions by a bond of causation. A disjunctivist approach, in contrast, claims that action must be distinguished by more than merely its etiology: action and mere movement are fundamentally different kinds. Recent objections to the causal theory of action are first surveyed, and the (...) common causalist assumption claiming Aristotle as the progenitor of the causal theory is examined and dismissed. More refined interpretations of Aristotle's thought on action yield two different concepts: action as change, and action as a unified psychophysical process. The latter in particular is argued to hold promise as a basis for developing the disjunctivist approach to action. The remainder of the thesis therefore considers a contemporary account of psychophysicality, known as 'embodiment theory', with the conclusion that the intelligibility of the account depends on appeal to a recent variant of top-down causation. The thesis also concludes that consideration of the concept of an animal agent makes it entirely unsurprising that the mental and physical are always found together in voluntary movement, and that the embodiment theory’s central notion of ‘property fusion’ potentially complements a naturalistic variant of top-down causation in explanations of agency.

The causal exclusion argument supports the notion that causation should be thought of as a purely low-level affair. Here we argue instead in favour of high-level causation as a natural and meaningful notion that may even be more useful than causation at more fundamental physical levels. Our argument is framed in terms of a broadly interventionist conception of causation. Its essence is that causal relations at an appropriately high level can in a certain sense be less (...) sensitive than those at a fundamental, microscopic level. This means that in settings where causal relations at the physical level are not considered in the context of some suitable macro-level interpretation, statements concerning the low-level relations may be highly sensitive with respect to changes in background conditions. Using an example of accelerator experiments in particle physics, we consider what it means to characterize extremely sensitive low-level events as causal. (shrink)

Sir Thomas Browne's reflection on the synthesis between his Christian religion and his practice as a medical doctor, made over three centuries ago, leads into reflections on the present relation between religion and science in the personal experience of the writer. An account is given of how the actual practice of scientific investigation led the author to theistic inferences and how the study of DNA provoked questions concerning reductionism and emergence. This evoked the need for a map of knowledge, and (...) an attempt is presented in a figure which also serves to clarify what kind of realistic reference is involved in both scientific and humanistic contexts–especially with respect to personal language. Theological investigations thereby receive at least provisional legitimization and, with this encouragement, the article pursues the questions of the nature of the divine Source (“God”) of the world's being and becoming, of God's interaction and communication with the world, especially with human beings in that world. The penultimate section outlines why the writer considers an explicit communication from God to humanity in Jesus of Nazareth is coherent with the foregoing and what this implies for human fulfillment, individually and corporately. The article concludes with a plea for humility before God and nature in our inquiries in the spirit both of Sir Thomas Browne and of the arch “agnostic” T. H. Huxley. (shrink)

I welcome with great enthusiasm Meling and Scheidegger’s (2023; henceforth “M&S”) timely contribution to advance an enactive approach to psychedelic therapy, especially to the complex causality involved. Their two main research questions concerned:(i) the causal interaction between the psychedelic molecule and brain activity; and (ii) the causal interaction between brain activity and the psychedelic experience. While I largely agree with and celebrate much of what is proposed by M&S, especially their employment of key enactive concepts to advance our understanding of (...) the first research question, in the following, I will present some worries regarding their answers to the second. Although I agree that there is probably a two-way reciprocal relationship between neural activity and experience, I have several points of contention regarding M&S’s proposal. My hope is to stimulate discussion on M&S’s important contribution, and to help advance a much-needed enactive science of psychedelics. (shrink)

This is a summary of the main arguments of 'A Metaphysics for Freedom' (Oxford: OUP, 2012).

The article proposes to further develop the ideas of the Extended Evolutionary Synthesis by including into evolutionary research an analysis of phenomena that occur above the organismal level. We demonstrate that the current Extended Synthesis is focused more on individual traits (genetically or non-genetically inherited) and less on community system traits (synergetic/organizational traits) that characterize transgenerational biological, ecological, social, and cultural systems. In this regard, we will consider various communities that are made up of interacting populations, and for which the (...) individual members can belong to the same or to different species. Examples of communities include biofilms, ant colonies, symbiotic associations resulting in holobiont formation, and human societies. The proposed model of evolution at the level of communities revises classic theorizing on the major transitions in evolution by analyzing the interplay between community/social traits and individual traits, and how this brings forth ideas of top-down regulations of bottom-up evolutionary processes (collaboration of downward and upward causation). The work demonstrates that such interplay also includes reticulate interactions and reticulate causation. In this regard, we exemplify how community systems provide various non-genetic ‘scaffoldings’, ‘constraints’, and ‘affordances’ for individual and sociocultural evolutionary development. Such research complements prevailing models that focus on the vertical transmission of heritable information, from parent to offspring, with research that instead focusses on horizontal, oblique and even reverse information transmission, going from offspring to parent. We call this reversed information transfer the ‘offspring effect’ to contrast it from the ‘parental effect’. We argue that the proposed approach to inheritance is effective for modelling cumulative and distributed developmental process and for explaining the biological origins and evolution of language.

Two conceptual frameworks – in terms of phase space and in terms of structural equations – are sketched, in which downward causal influence of higher-level features on lower-level features is possible. The “Exclusion” principle, which is a crucial premise of the argument against the possibility of downward causation, is false in models constructed within both frameworks. Both frameworks can be supplemented with conceptual tools that make it possible to explain why downward causal influence is not only conceivable and compatible (...) with the “Closure” principle, but also why it is often relevant to causally explain facts in terms of downward causal influence. It is briefly shown that the analysis of downward causation in the two frameworks complements Bennett’s analysis of overdetermination, the analysis does not entail the failure of the “Closure” principle and it does not require the postulate of synchronic downward causation.

Recent work in cognitive and computational neuroscience depicts the human cortex as a multi-level prediction engine. This ‘predictive processing’ framework shows great promise as a means of both understanding and integrating the core information processing strategies underlying perception, reasoning, and action. But how, if at all, do emotions and sub-cortical contributions fit into this emerging picture? The fit, we shall argue, is both profound and potentially transformative. In the picture we develop, online cognitive function cannot be assigned to either the (...) cortical or the sub-cortical component, but instead emerges from their tight co-ordination. This tight co-ordination involves processes of continuous reciprocal causation that weave together bodily information and ‘top-down’ predictions, generating a unified sense of what’s out there and why it matters. The upshot is a more truly ‘embodied’ vision of the predictive brain in action. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Philosophy, Psychiatry, & Psychology 11.1 (2004) 65-70 [Access article in PDF] Top-Down and Bottom-Up in Delusion Formation Jakob Hohwy Keywords delusions, top-down, bottom-up, predictive coding Some delusions may arise as responses to unusual experiences (Davies et al. 2001; Maher 1974;). The implication is that delusion formation in some cases involves some kind of bottom-up mechanism—roughly, from perception to belief. Delusion formation may also involve some kind of (...) top-down mechanism. This could be in the shape of a patient's flawed background beliefs, or biases, which somehow modulate perception or ensure delusional interpretations of experience. There is little agreement about what kind of mechanism is primary in delusion formation, or, indeed, what the particular mechanisms and their neural substrates might be.In the evaluation of top-down and bottom-up mechanisms in delusion formation, a number of conceptual questions should be addressed (Davies and Coltheart 2000). For example, if there is an experiential component, why is a hypothesis with a delusional explanation of the unusual experience seen as relevant? Why do the subjects come to believe it tenaciously? How come some unusual experiences do not develop into delusions?A number of empirical findings also need to be taken into account: for example, the damage to the autonomic system in Capgras delusion (Ellis et al. 1997), the decreased ability for fast error correction in schizophrenia (Frith and Done 1989), modulation of activity in parietal cortex in delusions of alien control and other passivity experiences (Blakemore, Oakley, and Frith 2003), and also in schizophrenia, the increased sensitivity to self-produced stimuli, such as tickling oneself (Blakemore et al. 2000) and the sound of one's own voice (Ford et al. 2001).Theory choice can also be guided by philosophical doctrines about, for example, the nature of belief, the constitutive role of rationality, and intersubjectivity and the nature of judgements about the external world. It is natural, however, to let beliefs about philosophical doctrine be secondary to empirical findings and conceptual issues.The distinction between bottom-up and top-down mechanisms is particularly sharp in John Campbell's (2001) account of delusions and in Tim Bayne and Elisabeth Pacherie's (2004) discussion of Campbell. In this discussion, top-down approaches are associated with the general philosophical doctrine of rationalism, and bottom-up approaches with the philosophical doctrine of empiricism. Campbell's account is top-down because he posits delusional framework beliefs that arise directly as a result of brain damage or malfunction, and that work in some top-down fashion on the interpretation of experience. Bayne [End Page 65] and Pacherie convincingly defend empiricism against Campbell's rationalist account. Among their many other objections, they briefly puzzle about how a delusional framework belief (e.g., that one's spouse is an impostor) in a top-down fashion could cause the damage to the autonomic system seen in the Capgras and Cotard delusions (2004, 1). I think this is a very important objection because skin conductance data are part of the evidence for the bottom-up hypothesis concerning the Capgras delusion. We could add to this, for example, that it is mysterious how belief in a top-down fashion could cause people with schizophrenia to be worse at fast error correction than normal controls, to be better at tickling themselves than normal controls, and to have an increased response to the sound of their own voice.On the other hand, although the skin conductance response (SCR) evidence suggests a bottom-up approach to the Capgras delusion, it does not explain the character of the subjective experience that is hypothesized to give rise to the delusional belief: reduced SCR is not part of the experience itself (thanks to Ian Gold for discussion of this). Something more is required to give a full account of the type of experience that gives rise to the delusion. Further, as they stand, most bottom-up accounts are unable to account for why reality testing fails for beliefs based on these experiences.Neither rationalism nor empiricism on their own seem able to address the conceptual questions while paying...

Psychiatry is a discipline that deals with both the physical and the mental lives of individuals and though it is true that, largely because of this characteristic, different models are used for different disorders, there is still a remnant tendency towards reductionist views in the field. In this paper I argue that the available empirical evidence from psychiatry gives us reasons to question biological reductionism and that in its place we should adopt a pluralistic explanatory model that is more suited (...) to the needs of the discipline and to the needs of the patients it is meant to help. This will allow us to retain psychiatry as an autonomous science that can productively co-exist with neuroscience while also giving patients the kind of attention they need. I further argue that this same evidence supports a view of the mind that is anti-reductive and that allows that causation can be both bottom-up and top-down and that such a view is available in emergentism coupled with an interventionist model of causation.

Although it has long been known that time is a cue to causation, recent work with adults has demonstrated that causality can also influence the experience of time. In causal reordering (Bechlivanidis & Lagnado, 2013, 2016) adults tend to report the causally consistent order of events, rather than the correct temporal order. However, the effect has yet to be demonstrated in children. Across four pre-registered experiments, 4- to 10-year-old children (N=813) and adults (N=178) watched a 3-object Michotte-style ‘pseudocollision’. While (...) in the canonical version of the clip object A collided with B, which then collided with object C (order: ABC), the pseudocollision involved the same spatial array of objects but featured object C moving before object B (order: ACB), with no collision between B and C. Participants were asked to judge the temporal order of events and whether object B collided with C. Across all age groups, participants were significantly more likely to judge that B collided with C in the 3-object pseudocollision than in a 2-object control clip (where clear causal direction was lacking), despite the spatiotemporal relations between B and C being identical in the two clips (Experiments 1—3). Collision judgements and temporal order judgements were not entirely consistent, with some participants—particularly in the younger age range—basing their temporal order judgements on spatial rather than temporal information (Experiment 4). We conclude that in both children and adults, rather than causal impressions being determined only by the basic spatial-temporal properties of object movement, schemata are used in a top-down manner when interpreting perceptual displays.

This paper investigates the degree to which information theory, and the derived uses that make it work as a metaphor of our age, can be helpful in thinking about God’s immanence and transcendance. We ask when it is possible to say that a consciousness has to be behind the information we encounter. If God is to be thought about as a communicator of information, we need to ask whether a communication system has to pre-exist to the divine and impose itself (...) to God. If we want God to be Creator, and not someone who would work like a human being, ‘creating’ will mean sustaining in being as much the channel, the material system, as the message. Is information control? It seems that God’s actions are not going to be informational control of everything. To clarify the issue, we attempt to distinguish two kinds of ‘genialities’ in nature, as a way to evaluate the likelihood of God from nature. We investigate concepts and images of God, in terms of the history of ideas but also in terms of philosophical theology, metaphysics, and religious ontology. (shrink)
