Downward Causation

Fundamental to Computer Science is the distinction between abstractions and implementations. When that distinction is applied to various philosophical questions it yields the following conclusions. -/- • EMERGENCE. It isn’t as mysterious as it’s made out to be; the possibility of strong emergence is not a threat to science. -/- • INTERACTIONS BETWEEN HIGHER-LEVEL ENTITIES. Physical interaction among higher-level entities is illusory. Abstract interactions are the source of emergence, new domains of knowledge, and complex systems. -/- • PHYSICS and the (...) SPECIAL SCIENCES. The new domains of knowledge derived from abstract interactions are the basis of the autonomy of the special sciences. -/- • DOWNWARD CAUSATION. It’s a zombie idea that should have a stake put through its heart and be replaced by downward entailment. (shrink)

Contemporary complexity theory has been instrumental in providing novel rigorous definitions for some classic philosophical concepts, including emergence. In an attempt to provide an account of emergence that is consistent with complexity and dynamical systems theory, several authors have turned to the notion of constraints on state transitions. Drawing on complexity theory directly, this paper builds on those accounts, further developing the constraint-based interpretation of emergence and arguing that such accounts recover many of the features of more traditional accounts. We (...) show that the constraint-based account of emergence also leads naturally into a meaningful definition of self-organization, another concept that has received increasing attention recently. Along the way, we distinguish between order and organization, two concepts which are frequently conflated. Finally, we consider possibilities for future research in the philosophy of complex systems, as well as applications of the distinctions made in this paper. (shrink)

The enduring problem of free will has defied resolution across centuries. There is reason to believe that novel factors must be integrated into the analysis to make progress. Within the current physicalist framework, these factors encompass emergence and information theory, in the context of constraints imposed by physical limits on the representation of information. Furthermore the common, but vague, characterization of free will as 'being able to act differently' is rephrased into an explicatum more suitable for formal analysis. It is (...) argued that the mind is an ontologically open system; a causal high-level system, the dynamics of which cannot be reduced to the states of its associated low-level neural systems, not even if it is rendered physically closed. A positive answer to the question of free will for conscious agents is subsequently outlined. (shrink)

The problem of free will has persistently resisted a solution throughout centuries. There is reason to believe that new elements need to be introduced into the analysis in order to make progress. In the present physicalist approach, these elements are emergence and information theory in relation to universal limits set by quantum physics. Furthermore the common, but vague, characterization of free will as "being able to act differently" is, in the spirit of Carnap, rephrased into an explicatum more suitable for (...) formal analysis. It is argued that the mind is an ontologically open system; a causal high-level system, the future of which cannot be reduced to the states of its associated low-level neural systems, not even if it is rendered physically closed. A positive answer to the question of free will is subsequently outlined. (shrink)

Libertarian free will is, roughly, the view that the same agential states can cause different possible actions. Nonreductive physicalism is, roughly, the view that mental states cause actions to occur, while these actions also have sufficient physical causes. Though libertarian free will and nonreductive physicalism have overlapping subject matter, and while libertarian free will is currently trending at the same time as nonreductive physicalism is a dominant metaphysical posture, there are few sustained expositions of a nonreductive physicalist model of libertarian (...) free will – indeed some tell against such an admixture. This paper concocts such a blend by articulating and defending, with some caveats, a nonreductive physicalist model of libertarian free will. (shrink)

Setting aside all exclusion-style worries about the redundancy of postulating additional, non-physical mental causes for effects that can already be explained in purely physical terms, dualists who treat mental properties as supervening on physical properties still face a further problem: in cases of mental-to-mental causation, they cannot avoid positing an implausibly coincidental coordination in the timing of the distinct causal processes terminating, respectively, in the mental effect and its physical base. I argue that this problem arises regardless of whether one (...) treats the mental cause as causing both the mental effect and its physical base, or whether one treats the latter as having instead been caused by some physical state, and that the problem also does not depend on which theory of causation one adopts. A third option of treating the mental cause and its physical base as producing the mental effect and its physical base by a single causal process that they both contribute to is found to come up short as well.

The causal closure of the physical poses a familiar causal exclusion problem for the special sciences that stems from the idea that if closure is true, then fundamental physical properties do all the causal work involved in bringing about physical effects. In this paper I aim to show that the strongest causal closure principle that is not ruled out by some simple physics in fact allows for a certain kind of downward causation, which in turn makes room for robust special (...) science autonomy. I focus on the case of vector composition, arguing that it involves irreducibly multilevel causation. To give a complete causal explanation of what goes on in cases that involve the effects of multiple forces, we need to appeal not only to the fundamental properties that generate those forces, but also to geometric properties that determine how multiple vectors compose. However, if all the causal work involved in such cases were due to fundamental physical properties, there would be a one-level explanation available. Hence, I argue, it cannot be the case that fundamental physical properties do all the causal work. The extra causal work, I suggest, comes from the fact that the causal powers bestowed by fundamental physical properties have irreducibly geometric manifestation conditions. I defend the resulting form of downward causation as a solution to the problem of special science autonomy, and discuss two potential accounts of its source, in terms of the debate between kinematic and dynamic theories of the origins of spacetime symmetries.

The standard objection to dualist theories of mind is that they seemingly cannot account for the obvious fact that mental phenomena cause our behaviour. On the plausible assumption that all our behaviour is physically necessitated by entirely physical phenomena, there appears to be no room for dualist mental causation. Some argue that dualists can address this problem by making minimal adjustments in their ontology. I argue that no such adjustments are required. Given recent developments in philosophy of causation, it is (...) plausible that mental phenomena cause behaviour in standard dualist ontologies. (shrink)

Is there such a thing as mental causation? Is it possible for the mental to have causal influence on the physical? Or has the old “mind over matter” question been rendered obsolete by the advent of brain science? Whatever our answers to these questions, it seems that we cannot systematically pursue them without considering what makes mental causation problematic in the first place: The causal closure of the physical world. This paper revisits the problem of mental causation by drawing on (...) a classical debate between Dharmakirti and the Indian materialists. The main argument of the paper is that expanding our conception of causality to accommodate phenomenal content can cast new light on the problem of mental causation. A satisfactory solution to the problem of mental causation must reject the completeness of the physical principle in favor of conceptions of causality that allow for phenomenal properties to play a causal-explanatory function. (shrink)

In this paper I argue that many scholars involved in the contemporary free will debates have underappreciated the philosophical appeal of agent causation because the resources of contemporary emergentism have not been adequately introduced into the discussion. Whereas I agree that agent causation’s main problem has to do with its intelligibility, particularly with respect to the issue of how substances can be causally relevant, I argue that the notion of substance causation can be clearly articulated from an emergentist framework. According (...) to my proposal, a free agent is _a causally powerful substance that emerges in an anomic way from her constitutive mental events_, downwardly constraining, selecting and, in this way, having control on them. As we shall see, this particular concept of agent causation not only makes sense of the deep insight behind agent libertarianism, but it also provides us with the resources to solve some of the main objections that have been raised against it. It is true that here I cannot develop a complete defense of the evidential credentials of emergentism. Still, even if the considerations that follow do not serve to convince detractors of agent causal libertarian accounts of free will, they do suggest that libertarian agent causation is more promising than is typically acknowledged.

The article summarizes the software tool on astrophysical analysis with multi-wavelength space telescope data. It recaps the evidence analysis conducted on the Kerr-Newman black hole (KNBH). It was written prior to the article Research on the Kerr-Newman Black Hole in M82 Confirms Black Hole and White Hole Juxtapose not soon after the experiment. The conducted analysis suggested Hawking radiation is caused by the movement of ergosurfaces of the BH and serves as the primal evidence for black hole and white hole (...) juxtapose. A later data exploration was conducted with the radiation trails in the multi-wavelength data. The evidences produced corroborates with Yale professor Priyamvada Natarajan's black hole seeds theory. It implies that the electromagnetic dynamic of fusion and fission temperature determines the pressure of surface tension on the macro particles, and the mass density of the BH is determined by the electromagnetic tension between the outer ergosurface and inner ergosurface. The ring singularity of the BH and the Penrose-Hawking singularity of the BH determine the spin and gravitational singularity of the BH. Inside the ergosurfaces, the BH singularities' backward inflow causes the vicinity's rate on feeding the BH. It makes the active galactic nuclei (AGN) a semi-closed system. The density pressure is released on threshold. During the mass exchange observed by energy momentum upon the AGN's open, the macroparticle composition of the BH changes with the galactic event. This causes the expansion rate of the galaxy and contraction rate of the BH. AGN types and their relative motions determine the expansion rate of the cosmic universe in a generalized quantitative thinking. The article concludes that BH spin is caused by the asymmetric motions of AGN in the BH system. A set of the nuclear resonance caused by BH and white hole (WH) oscillation is processed with the same set of data. (shrink)

Neste artigo, discuto o problema das propriedades emergentes, começando por apresentar uma concepção tradicional de acordo com a qual estas propriedades exibem três características definidoras: elas dependem de propriedades e relações físicas, mas constituem, em relação a estas, uma novidade e, como tal, não são delas deduzíveis. Em primeiro lugar, discuto algumas das razões gerais que explicam o facto de tradicionalmente se supor que este tipo de novidade – e.g. causal ou qualitativa – parece exigir que as propriedades emergentes não (...) se encontram, de todo, fisicamente fundadas, não podendo ser deduzidas das suas bases físicas. Portanto, a dependência física das propriedades emergentes não pode ser explicada, o que é normalmente tido como misterioso. Recorrendo a uma concepção funcionalista de dedutibilidade, discuto de seguida, com mais detalhe, a relação entre a novidade e a não-dedutibilidade, realçando o modo como os diferentes tipos de não-dedutibilidade conduzem a diferentes tipos de novidade e, como tal, a diferentes formas de emergência. Finalmente, considero algumas abordagens científicas modernas que rejeitam a não-dedutibilidade enquanto condição necessária da emergência. Segundo tais abordagens, o tipo de novidade associado às propriedades emergentes é compatível com uma fundação física, o que, por sua vez, faz desvanecer o mistério e confere respeitabilidade científica à noção de emergência. Concluirei estabelecendo comparações entre estas abordagens e o hilomorfismo neo-Aristotélico. (shrink)

Negli ultimi anni, il richiamo al concetto di emergenza si è fatto sempre più diffuso in molte aree della filosofia e della scienza. Il termine viene usato per riferirsi alla circostanza in cui un sistema (fisico, chimico, biologico, ma anche sociale) manifesta delle proprietà e dei comportamenti che sembrano nuovi rispetto a quelli delle sue parti più semplici. Questo libro si propone di chiarire questo fenomeno, tenendo conto, da un lato, che le discipline coinvolte nel dibattito sono molte, quindi un (...) approccio univoco all'emergenza potrebbe non bastare e, dall'altro, che per comprendere cosa sia l'emergenza è necessario delinearne le relazioni con altre questioni filosofiche di primaria importanza come quelle che coinvolgono la fondamentalità, la complessità e la causalità.

Emergence is typically discussed in the context of mental properties or the properties of the natural sciences, and accounts of emergence within these contexts tend to look a certain way. The emergent property is taken to emerge instantaneously out of, or to be proximately caused by, complex interaction of colocated entities. Here, however, I focus on the properties instantiated by the elements of certain systems discussed in social ontology, such as being a five-dollar bill or a pawn-movement, and I suggest (...) that these properties emerge in a distinctive way. They emerge in part because of a system that is far beyond and typically before the object that instantiates them. I characterize how emergence occurs in these cases, juxtaposing it with how emergence is typically discussed. I then consider whether their emergence is best framed as weak or strong as these notions are characterized in the literature, and I reveal what debates are central to answering this question. Though I will not resolve these debates, I do show a collection of views that would vindicate these properties as strongly emergent and downwardly causing. (shrink)

The causal closure of the physical world is assumed everywhere in physics but has little empirical support within living organisms. For the spiritual to have effects in nature, and make a difference there, the laws of physical nature would have to be modified or extended. I propose that the renormalized parameters of quantum field theory (masses and charges) are available to be varied locally in order to achieve ends in nature. This is not adding extra forces to nature but rescaling (...) the forces which already exist. We separate metric time in 4 dimensions from process time as the order of actualization of potentialities. This is to allow iterative forward and reverse steps in metric time to influence intermediate variations in the vacuum permittivities to move charged bodies towards achieve specific targets at a later time. Then mental or spiritual influx could have effects in nature, and these should be measurable in biophysics experiments. With this proposal, we see after some centuries how ‘final causes’ could once again be seen active in nature. (shrink)

The uniqueness of each standpoint, each point of effect, can only be "overcome" by the standpoint changing to other standpoints and returning. In such alternation, which can also appear as constant change, lies the unity of the world. The wholeness of an alternation, however, is a structure of consciousness due to the special relationship between the circumscribing periphery and the infinitesimal center. This process structure unites determinacy and indeterminacy also totally in every place. Therefore, everywhere we are dealing with forms (...) of consciousness with more or less freedom of choice and an increasingly unknown depth. We live in a world of choosing consciousness, or rather awareness. In this respect, our environment expresses a deep truth about ourselves. (shrink)

Contemporary biological research has suggested that some host–microbiome multispecies systems (referred to as “holobionts”) can in certain circumstances evolve as unique biological individual, thus being a unit of selection in evolution. If this is so, then it is arguably the case that some biological adaptations have evolved at the level of the multispecies system, what we call hologenomic adaptations. However, no research has yet been devoted to investigating their nature, or how these adaptations can be distinguished from adaptations at the (...) species-level (genomic adaptations). In this paper, we cover this gap by investigating the nature of hologenomic adaptations. By drawing on the case of the evolution of sanguivory diet in vampire bats, we argue that a trait constitutes a hologenomic adaptation when its evolution can only be explained if the holobiont is considered the biological individual that manifests this adaptation, while the bacterial taxa that bear the trait are only opportunistic beneficiaries of it. We then use the philosophical notions of emergence and inter-identity to explain the nature of this form of individuality and argue why it is special of holobionts. Overall, our paper illustrates how the use of philosophical concepts can illuminate scientific discussions, in the trend of what has recently been called metaphysics of biology. (shrink)

The purpose of this paper is to address a well-known dilemma for physicalism. If mental properties are type identical to physical properties, then their causal efficacy is secure, but at the cost of ruling out mentality in creatures very different to ourselves. On the other hand, if mental properties are multiply realizable, then all kinds of creatures can instantiate them, but then they seem to be causally redundant. The causal exclusion problem depends on the widely held principle that realized properties (...) inherit their causal powers from their realizers. While this principle holds for functional realization, it fails on a broader notion of realization that permits the realization of complex qualitative properties such as spatial and temporal patterns. Such properties are best seen as dependent powerful qualities, which have their causal roles in virtue of being the qualities they are, and do not inherit powers from their realizers. Recent studies have identified one such property—neural synchrony—as a correlate of consciousness. If synchrony is also partially constitutive of consciousness, then phenomenal properties are both multiply realizable and causally novel. I outline a version of representationalism about consciousness on which this constitution claim holds. (shrink)

The received view in physicalist philosophy of mind assumes that causation can only take place at the physical domain and that the physical domain is causally closed. It is often thought that this leaves no room for mental states qua mental to have a causal influence upon the physical domain, leading to epiphenomenalism and the problem of mental causation. However, in recent philosophy of causation there has been growing interest in a line of thought that can be called causal antifundamentalism: (...) causal notions cannot play a role in physics, because the fundamental laws of physics are radically different from causal laws. Causal anti-fundamentalism seems to challenge the received view in physicalist philosophy of mind and thus raises the possibility of there being genuine mental causation after all. This paper argues that while causal anti-fundamentalism provides a possible route to mental causation, we have reasons to think that it is incorrect. Does this mean that we have to accept the received view and give up the hope of genuine mental causation? I will suggest that the ontological interpretation of quantum theory provides us both with a view about the nature of causality in fundamental physics, as well as a view how genuine mental causation can be compatible with our fundamental (quantum) physical ontology.

Holobionts are symbiotic assemblages composed by a host plus its microbiome. The status of holobionts as individuals has recently been a subject of continuous controversy, which has given rise to two main positions: on the one hand, holobiont advocates argue that holobionts are biological individuals; on the other, holobiont detractors argue that they are just mere chimeras or ecological communities, but not individuals. Both parties in the dispute develop their arguments from the framework of the philosophy of biology, in terms (...) of what it takes for a “conglomerate” to be considered an interesting individual from a biological point of view. However, the debates about holobiont individuality have important ontological implications that have remained vaguely explored from a metaphysical framework. The purpose of this paper is to cover that gap by presenting a metaphysical approach to holobionts individuality. Drawing upon a conception of natural selection that puts the focus on the transgenerational recurrence of the traits and that supports the thesis that holobionts are units of selection, we argue that holobionts bear emergent traits and exert downward powers over the entities that compose them. In this vein, we argue, a reasonable argument can be made for conceiving holobionts as emergent biological individuals. (shrink)

Jaegwon Kim’s views on mental causation and the exclusion argument are evaluated systematically. Particular attention is paid to different theories of causation. It is argued that the exclusion argument and its premises do not cohere well with any systematic view of causation.

Paul Humphreys’ main aim in this wide-ranging and ambitious book is to defend a novel account of ontological emergence he refers to as transformational emergence. His secondary aims are many: to show how ontological emergence so understood can be usefully seen against the backdrop of a reductionist position he calls generative atomism ; to compare and contrast his preferred position with historical and contemporary alternatives; and to consider a range of scientific cases both as potential examples of ontological emergence and (...) of weaker forms of emergence stemming from our computational or conceptual limitations. Humphreys is clear from the outset that the range of scientific cases that satisfy certain positive criteria for emergence is too diverse for a single, unified account, and he is more concerned to highlight the differences that preclude such an account than to abstract away from them. The result is a mosaic of case studies, to which are applied a range of alternative conceptions of emergence, drawing out various similarities and differences between the cases, and assessing their credentials as emergent according to the various alternative conceptions considered.

In this paper, I shall argue that both emergence and downward causation, which are strongly interconnected, presuppose the presence of levels of reality. However, emergence and downward causation pull in opposite directions with respect to my best reconstruction of what levels are. The upshot is that emergence stresses the autonomy among levels while downward causation puts the distinction between levels at risk of a reductio ad absurdum, with the further consequence of blurring the very notion of downward. Therefore, emergence and (...) downward causation are not fit to each other vis-a-vis the concept of level. (shrink)

Providing empirically supportable instances of ontological emergence is notoriously difficult. Typically, the literature has focused on two possible sources. The first is the mind and consciousness; the second is within physics, and more specifically certain quantum effects. In this paper, I wish to suggest that the literature has overlooked a further possible instance of emergence, taken from the special science of linguistics. In particular, I will focus on the property of truth-evaluability, taken to be a property of sentences as created (...) by the language faculty within human minds (or brains). The claim will not be as strong as to suggest that the linguistic data and theories prove emergence. Rather the dialectical aim here is to say that we have some good reasons (even if not conclusive reasons) to think that the property is emergent. (shrink)

Western philosophy and science have a strongly dualistic tradition regarding the mental and physical aspects of reality, which makes it difficult to understand their possible causal relations. In recent debates in cognitive neuroscience it has been common to claim on the basis of neural experiments that conscious experiences are causally inefficacious. At the same time there is much evidence that consciousness does play an important role in guiding behavior. The author explores whether a new way of understanding the causal role (...) of mental states and consciousness could be provided by the ontological interpretation of the quantum theory (Bohm and Hiley, Phys. Rep. 144:323–348, 1987; Bohm and Hiley, The undivided universe: An ontological interpretation of quantum theory. Routledge: London, 1993). This interpretation radically changes our notion of matter by suggesting that a new type of active information plays a causal role at the quantum level of reality. The author thus considers to what extent the alleged causal powers of consciousness involve information, and then moves on to consider whether information in (conscious) mental states can be connected to the information at the level of quantum physics. In this way he sketches how quantum theory might help to throw light upon one of the grand challenges facing the social sciences and the humanities, namely the question of whether consciousness plays any genuine causal role in the physical world.

Despite its recent popularity, Emergence is still a field where philosophers and physicists often talk past each other. In fact, while philosophical discussions focus mostly on ontological emergence, physical theory is inherently limited to the epistemological level and the impossibility of its conclusions to provide direct evidence for ontological claims is often underestimated. Nevertheless, the emergentist philosopher’s case against reductionist theories of how the different levels of reality are related to each other can still gain from the assessment of paradigmatic (...) examples of discontinuity between models in physics, even though their implications must be handled with care.

Widespread causal overdetermination is often levied as an objection to nonreductive theories of minds and objects. In response, nonreductive metaphysicians have argued that the type of overdetermination generated by their theories is different from the sorts of coincidental cases involving multiple rock-throwers, and thus not problematic. This paper pushes back. I argue that attention to differences between types of overdetermination discharges very few explanatory burdens, and that overdetermination is a bigger problem for the nonreductive metaphysician than previously thought.

: In The Varieties of Consciousness, Kriegel argues that it is possible to devise a method to sort out the irreducible primitive phenomenologies that exist. In this paper I argue that his neutrality notwithstanding, Kriegel assumes a form of realism that leaves unresolved many of the conundrums that characterize the debate on consciousness. These problems are evident in the centrality he assigns to introspection and his characterization of cognitive phenomenology. Keywords : Consciousness; Introspection; Realism; Type-identity; Dispositional Properties I primitivi della (...) coscienza e la loro realtà Riassunto : In The Varieties of Consciousness Kriegel sostiene la possibilità di concepire un metodo per mettere ordine tra le esperienze fenomenicamente primitive effettivamente esistenti, ciascuna nella propria irriducibilità rispetto alle altre.

This work attempts to respond to Tomas Aquinas' Cosmological Argument in a way that combines Set Theory with the idea of the ‘Book of Change’. The study defines the ith Cause Set on which to operate on, which leads to the ontological commitment of austerity that the ‘First Cause's Compromise with emergence’ cannot be avoided. It is argued in the present paper that the concept that ‘emergence only consists of Synchronic Emergence and Diachronic Emergence’ should be extended to a broader (...) notion of emergence, which is made up of the two discussed elements and a third one ‘No-Boundary Emergence’ (beyond the time dimension). The article defines the concept of No-Boundary Emergence, proves why it is a type of emergence that differs from the traditional two types, and asserts that it underlies the bottom layer of the cosmos. This study describes the common feature of all emergence as communication protocols between layers. The assemblage of all emergences behaves similar to a distributed system that cannot be restricted by Gödel's theorem. The paper provides evidence (in Big Bang Cosmology, Conformal Cyclic Cosmology, Superstring Theory, Quantum Gravity) for this point of view, and notes that emergence (in the context of No-Boundary Emergence) is not only a simple scientific theory but also a progressive scientific research programme that can spontaneously grow from scientific theory based on Platonism at the expense of a degenerating shift to the ontological commitment of austerity. This paper proposes an improved model of Schrödinger Cat that provides a new explanation for quantum measurement and argues that there must be a forbidden zone of thought experiments. The study also introduces the implications of ancient Chinese thoughts (namely, the ‘Book of Change’ and Confucius). The paper comes to the conclusion that emergence (crossing the gap between ‘being’ and ‘nothing’, while ignoring the forbidden zone of thought experiments) relieves ‘cosmological insufficiency’ in the sense of Neo-Aristotelism.

Are the special sciences autonomous from physics? Those who say they are need to explain how dependent special science properties could feature in irreducible causal explanations, but that’s no easy task. The demands of a broadly physicalist worldview require that such properties are not only dependent on the physical, but also physically realized. Realized properties are derivative, so it’s natural to suppose that they have derivative causal powers. Correspondingly, philosophical orthodoxy has it that if we want special science properties to (...) bestow genuinely new causal powers, we must reject physical realization and embrace a form of emergentism, in which such properties arise from the physical by mysterious brute determination. In this paper, I argue that contrary to this orthodoxy, there are physically realized properties that bestow new causal powers in relation to their realizers. The key to my proposal is to reject causal-functional accounts of realization and embrace a broader account that allows for the realization of shapes and patterns. Unlike functional properties, such properties are defined by qualitative, non-causal specifications, so realizing them does not consist in bestowing causal powers. This, I argue, allows for causal novelty of the strongest kind. I argue that the molecular geometry of H2O—a qualitative, multiply realizable property—plays an irreducible role in explaining its dipole moment, and thereby bestows novel powers. On my proposal, special science properties can have the kind of causal novelty traditionally associated with strong emergence, without any of the mystery. (shrink)

In this paper, I argue for the usefulness of pragmatism as a framework within which to develop the theological application of emergentist theory. I consider some philosophical issues relevant to the recent revival of interest, across various disciplines, in the concept of emergence and clarify some of the conceptual issues at stake in the attempts to formulate the philosophical position of emergentism and to apply it theologically. After highlighting some major problems arising from the main existing ways of formulating emergentism, (...) I build on the work of Sami Pihlström, outlining a less problematic, alternative proposal. I attempt to show that the philosophical problems can be circumvented by an appeal to the pragmatist tradition, which is a useful philosophical framework within which to develop an emergentist theory fit for theological application.

The idea of levels of organization plays a central role in the philosophy of the life sciences. In this article, I first examine the explanatory goals that have motivated accounts of levels of organization. I then show that the most state-of-the-art and scientifically plausible account of levels of organization, the account of levels of mechanism proposed by Bechtel and Craver, is fundamentally problematic. Finally, I argue that the explanatory goals can be reached by adopting a deflationary approach, where levels of (...) organization give way to more well-defined and fundamental notions, such as scale and composition.

The problem of free will is deeply linked with the causal relevance of mental events. The causal exclusion argument claims that, in order to be causally relevant, mental events must be identical to physical events. However, Gibb has recently criticized it, suggesting that mental events are causally relevant as double preventers. For Gibb, mental events enable physical effects to take place by preventing other mental events from preventing a behaviour to take place. The role of mental double preventers is hence (...) similar to what Libet names free won’t, namely the ability to veto an action initiated unconsciously by the brain. In this paper I will propose an argument against Gibb’s account, the causal irrelevance argument, showing that Gibb’s proposal does not overcome the objection of systematic overdetermination of causal relevance, because mental double preventers systematically overdetermine physical double preventers, and therefore mental events are causally irrelevant.

For over 20 years, Jaegwon Kim’s Causal Exclusion Argument has stood as the major hurdle for non-reductive physicalism. If successful, Kim’s argument would show that the high-level properties posited by non-reductive physicalists must either be identical with lower-level physical properties, or else must be causally inert. The most prominent objection to the Causal Exclusion Argument—the so-called Overdetermination Objection—points out that there are some notions of causation that are left untouched by the argument. If causation is simply counterfactual dependence, for example, (...) then the Causal Exclusion Argument fails. Thus, much of the existing debate turns on the issue of which account of causation is appropriate. In this paper, however, I take a bolder approach and argue that Kim’s preferred version of the Causal Exclusion Argument fails no matter what account one gives of causation. Any notion of causation that is strong enough to support the premises of the argument is too strong to play the role required in the logic of the argument. I also consider a second version of the Causal Exclusion Argument, and suggest that although it may avoid the problems of the first version, it begs the question against a particular form of non-reductive physicalism, namely emergentism.

I show that the recent account of levels in neuroscience proposed by Craver and Bechtel is unsatisfactory since it fails to provide a plausible criterion for being at the same level and is incompatible with Craver and Bechtel’s account of downward causation. Furthermore, I argue that no distinct notion of levels is needed for analyzing explanations and causal issues in neuroscience: it is better to rely on more well-defined notions such as composition and scale. One outcome of this is that (...) apparent cases of downward causation can be analyzed away. (shrink)

The methodological nonreductionism of contemporary biology opens an interesting discussion on the level of ontology and the philosophy of nature. The theory of emergence (EM), and downward causation (DC) in particular, bring a new set of arguments challenging not only methodological, but also ontological and causal reductionism. This argumentation provides a crucial philosophical foundation for the science/theology dialogue. However, a closer examination shows that proponents of EM do not present a unified and consistent definition of DC. Moreover, they find it (...) difficult to prove that higher-order properties can be causally significant without violating the causal laws that operate at lower physical levels. They also face the problem of circularity and incoherence in their explanation. In our article we show that these problems can be overcome only if DC is understood in terms of formal rather than physical (efficient) causality. This breakdown of causal monism in science opens a way to the retrieval of the fourfold Aristotelian notion of causality. (shrink)

Recent years have seen renewed interest in the emergence issue. The contemporary debate, in contrast with that of past times, has to do not so much with the mind–body problem as with the relationship between the physical and other domains; mostly with the biological domain. One of the main sources of this renewed interest is the study of complex and, in general, far-from-equilibrium self-preserving systems, which seem to fulfil one of the necessary conditions for an entity to be emergent; namely, (...) that its causal powers are not predictable from the causal powers of basic physical properties. However, I argue that much of the current emergentism debate has misfired by focusing on the interpretation of self-maintaining systems. In contrast, I claim that if we want to find emergent properties, we should look not at complex systems, but at selection (natural selection, in particular). I argue that selection processes make the causal world ‘exuberant’ by making non-physical functional and relational properties enter the causal web of the world. (shrink)

This article surveys different forms of emergence, distinguishing them from each other by means of their relationship to deducibility conceived as Kimian functional reduction.

Downward causation is commonly held to create problems for ontologically emergent properties. In this paper I describe two novel examples of ontologically emergent properties and show how they avoid two main problems of downward causation, the causal exclusion problem and the causal closure problem. One example involves an object whose colour does not logically supervene on the colours of its atomic parts. The other example is inspired by quantum entanglement cases but avoids controversies regarding quantum mechanics. These examples show that (...) the causal exclusion problem can be avoided, in one case by showing how it is possible to interact with an object without interacting with its atomic parts. I accept that emergence cannot be reconciled with causal closure, but argue that violations of causal closure do not entail violations of the base-level laws.

Peirce's pragmatic notion of semiosis can be described in terms of a multi-level system of constraints involving chance, efficient, formal and final causation. According to the model proposed here, law-like regularities, which work as boundary conditions or organizational principles, have a downward effect on the spatiotemporal distribution of lower-level semiotic items. We treat this downward determinative influence as a propensity relation: if some lower-level entities a,b,c,-n are under the influence of a general organizational principle, W, they will show a tendency (...) to behave in certain specific ways, and, thus, to instantiate a set of specific processes. Our goal in this paper is to examine the role of downward determination in semiotic systems, conceived as multi-level hierarchical systems. (shrink)

Der Artikel diskutiert Niklas Luhmanns Konzeption von Kommunikation als emergentem Phänomen. Erstens soll gezeigt werden, dass sich Luhmann, entgegen jüngster Einwände, in der Tat als sozialer Emergentist rekonstruieren und als solcher in die aktuelle Debatte um Reduktion und Emergenz des Sozialen einordnen lässt. Zweitens soll dadurch Licht auf die generellen Probleme und Voraussetzungen einer emergentistischen Soziologie geworfen werden. Um diese Ziele zu erreichen, wird zunächst geklärt, welche Positionen sich in der Soziologie grundsätzlich gegenüber stehen und auf welcher Grundlage Luhmann als (...) Emergentist einzuordnen ist. Anschließend soll die Emergenz der Kommunikation als eigenständiges soziales Phänomen erläutert und ins Verhältnis zum Individuum gesetzt werden. Schließlich wird Luhmanns Konzeption mit Hilfe einiger Adäquatheitsbedingungen aus der allgemeinen Wissenschaftsphilosophie als unzureichend kritisiert. Ziel ist dabei auch die Klärung der Bedingungen für eine plausible Emergenztheorie innerhalb der Soziologie. Nach einer abschließenden Zusammenfassung der wesentlichen Ergebnisse soll ein Ausblick auf eine aussichtsreiche soziologische Emergenzkonzeption geboten werden. (shrink)

Symmetries play a major role in physics, in particular since the work by E. Noether and H. Weyl in the first half of last century. Herein, we briefly review their role by recalling how symmetry changes allow to conceptually move from classical to relativistic and quantum physics. We then introduce our ongoing theoretical analysis in biology and show that symmetries play a radically different role in this discipline, when compared to those in current physics. By this comparison, we stress that (...) symmetries must be understood in relation to conservation and stability properties, as represented in the theories. We posit that the dynamics of biological organisms, in their various levels of organization, are not just processes, but permanent (extended, in our terminology) critical transitions and, thus, symmetry changes. Within the limits of a relative structural stability (or interval of viability), variability is at the core of these transitions. (shrink)

Many researchers consider cancer to have molecular causes, namely mutated genes that result in abnormal cell proliferation (e.g. Weinberg 1998). For others, the causes of cancer are to be found not at the molecular level but at the tissue level where carcinogenesis consists of disrupted tissue organization with downward causation effects on cells and cellular components (e.g. Sonnenschein and Soto 2008). In this contribution, I ponder how to make sense of such downward causation claims. Adopting a manipulationist account of causation (...) (Woodward 2003), I propose a formal definition of downward causation and discuss further requirements (in light of Baumgartner 2009). I then show that such an account cannot be mobilized in support of non-reductive physicalism (contrary to Raatikainen 2010). However, I also argue that such downward causation claims might point at particularly interesting dynamic properties of causal relationships that might prove salient in characterizing causal relationships (following Woodward 2010).

The systems studied in the special sciences are often said to be causally autonomous, in the sense that their higher-level properties have causal powers that are independent of the causal powers of their more basic physical properties. This view was espoused by the British emergentists, who claimed that systems achieving a certain level of organizational complexity have distinctive causal powers that emerge from their constituent elements but do not derive from them. More recently, non-reductive physicalists have espoused a similar view (...) about the causal autonomy of special-science properties. They argue that since these properties can typically have multiple physical realizations, they are not identical to physical properties, and further they possess causal powers that differ from those of their physical realisers. Despite the orthodoxy of this view, it is hard to find a clear exposition of its meaning or a defence of it in terms of a well-motivated account of causation. In this paper, we aim to address this gap in the literature by clarifying what is implied by the doctrine of the causal autonomy of special-science properties and by defending the doctrine using a prominent theory of causation from the philosophy of science.

The issue of downward causation (and mental causation in particular), and the exclusion problem is discussed by taking into account some recent advances in the philosophy of science. The problem is viewed from the perspective of the new interventionist theory of causation developed by Woodward. It is argued that from this viewpoint, a higher-level (e.g., mental) state can sometimes truly be causally relevant, and moreover, that the underlying physical state which realizes it may fail to be such.
