The evolution of the human mind through natural selection mandates that our conscious experiences are causally potent in order to leave a tangible impact upon the surrounding physical world. Any attempt to construct a functional theory of the conscious mind within the framework of classical physics, however, inevitably leads to causally impotent conscious experiences in direct contradiction to evolution theory. Here, we derive several rigorous theorems that identify the origin of the latter impasse in the mathematical properties of ordinary differential (...) equations employed in combination with the alleged functional production of the mind by the brain. Then, we demonstrate that a mind--brain theory consistent with causally potent conscious experiences is provided by modern quantum physics, in which the unobservable conscious mind is reductively identified with the quantum state of the brain and the observable brain is constructed by the physical measurement of quantum brain observables. The resulting quantum stochastic dynamics obtained from sequential quantum measurements of the brain is governed by stochastic differential equations, which permit genuine free will exercised through sequential conscious choices of future courses of action. Thus, quantum reductionism provides a solid theoretical foundation for the causal potency of consciousness, free will and cultural transmission. (shrink)

There is an argument whichshows conclusively that if qualia are causallyimpotent we could have no possible grounds forbelieving that they exist. But if, as this argumentshows, qualia are causally potent with respect to thedescriptions we give of them, it is tolerably certainthat they are causally potent in other morebiologically significant respects. The empiricalevidence, from studies of the effect of lesions of thestriate cortex shows that what is missing inthe absence of visual qualia is the ability tocategorize sensory inputs in the (...) visual modality. This would suggest that the function of privateexperience is to supply what Broadbent callsthe evidence on which the categorization ofproblematic sensory inputs are based. At the sametime analysis of the causal relation shows that whatdifferentiates a causal relation from an accidentalspatio-temporal conjunction is the existence ofreciprocally related dispositional properties of theentities involved which combine to make it true thatif one member of the conjunction, the cause, had notexisted, the other, the effect, would not haveexisted. The possibility that qualia might bedispositional properties of experiences which, as itwere, supply the invisible glue that sticks cause toeffect in this case is examined, but finallyrejected.

In this paper, I respond to the (infamous) causal impotence objection to the standard arguments for ethical vegetarianism. The paper defends a non-consequentialist response to this objection, one that draws on an account of the principle of non-maleficence inspired by Ross.

In this paper I argue against the worried view that intentional properties might be epiphenomenal. In naturalizing intentionality we ought to reject both the idea that causal powers of intentional states must supervene on local microstructures, and the idea that local supervenience justifies worries about intentional epiphenomenality since our states could counterfactually lack their intentional properties and yet have the same effects. I contend that what's wrong with even the good guys (e.g. Dennett, Dretske, Allen) is that they implicitly (...) grant that causal powers supervene locally. Finally, I argue that once we see the truth of an anti-individualism which sees cognition as a fundamentally embedded activity, it becomes clear both that granting local supervenience is granting too much, and that intentional properties do work that mere neurological properties could never do. I also suggest how a transcendental argument for intentional potency might go. (shrink)

I argue that Fred Dretske's account of the causal relevance of content only works if another account works better, that put forward by Gabriel Segal and Elliot Sober. Dretske needs to appeal to it to deal with two problems he faces: one arising because he accepts that the mere association between indicators and indicated is causally relevant to the recruitment of indicators in causing behaviour, the other from the need to explain how a present token of a certain type (...) of content is causally relevant. For this and other reasons their approach has clear advantages over Dretske's. (shrink)

In this paper I offer an anti-Humean critique to Williamson and Russo’s approach to medical mechanisms. I focus on one of the specific claims made by Williamson and Russo, namely the claim that micro-structural ‘mechanisms’ provide evidence for the stability across populations of causal relationships ascertained at the (macro-) level of (test) populations. This claim is grounded in the epistemic account of causality developed by Williamson, an account which—while not relying exclusively on mechanistic evidence for justifying causal judgements—appeals (...) nevertheless to mechanisms, and rejects their anti-Humean interpretation in terms of capacities, powers, potencies, etc. By using (and expanding on) Cartwright’s basic critique against Humean mechanisms, I suggest that, in order to move beyond the level of plausibility, Williamson and Russo’s position is in need of a clarification as to the occurent reading of the components, functioning and interferences of mechanisms. Relatedly, as concerns Williamson’s epistemic account of causation, I argue that this account is in need of a more straightforward answer as to what truth-makers its causal claims should have.

The simplest axioms, formulated by medieval scholastics as rules of inference between potency and act, are also axioms concerning causality as they express some potency-act relations. These are: Ab esse ad posse valet illatio. A non posse ad non esse valet illatio. A posse ad esse non valet illatio. A non esse ad non posse non valet illatio. The project on formulating axioms of efficient causality by means of the prepositional variables calculus does not mean of course that (...) we try to create a complete theory of causality. We will, for the moment show that the quantification of the concepts „potency-act" by means of the concepts „set-element" or „parameter-specific numerical value" is very useful. We will also point out, intuitively, as an experiment, the logical operators which are linked very closely with such concepts as implication, potentiality, act, set, specific numeric value. (shrink)

David Bohm's interpretation of quantum mechanics yields a quantum potential, Q. In his early work, the effects of Q are understood in causal terms as acting through a real (quantum) field which pushes particles around. In his later work (with Basil Hiley), the causal understanding of Q appears to have been abandoned. The purpose of this paper is to understand how the use of certain metaphors leads Bohm away from a causal treatment of Q, and to evaluate (...) the use of those metaphors. (shrink)

The natural evolution of consciousness in different animal species mandates that conscious experiences are causally potent in order to confer any advantage in the struggle for survival. Any endeavor to construct a physical theory of consciousness based on emergence within the framework of classical physics, however, leads to causally impotent conscious experiences in direct contradiction to evolutionary theory since epiphenomenal consciousness cannot evolve through natural selection. Here, we review recent theoretical advances in describing sentience and free will as fundamental aspects (...) of reality granted by quantum physical laws. Modern quantum information theory considers quantum states as a physical resource that endows quantum systems with the capacity to perform physical tasks that are classically impossible. Reductive identification of conscious experiences with the quantum information comprised in quantum brain states allows for causally potent consciousness that is capable of performing genuine choices for future courses of physical action. The consequent evolution of brain cortical networks contributes to increased computational power, memory capacity, and cognitive intelligence of the living organisms. (shrink)

This article offers a reading of Eriugena’s thought that is inspired by Heidegger’s claim according to which being is constituted in a dialectical interplay of revelation and concealment. Beginning with an analysis of how “causality as concealing revelation” works on the level of God’s inner-Trinitarian life, the piece moves on to a consideration of the way in which the human soul reveals itself in successive stages of exteriorization that culminate in the creation of the body, its “image.” The body, however, (...) conceals as much as it reveals true human nature. Moreover, it is shown that for Eriugena all of reality, as theophany, possesses this character of concealing its fundamental truth. These insights lead Eriugena to a recognition of radical human finitude, as genuine wisdom requires an acknowledgement of our fundamental ignorance. (shrink)

Saying so can make it so, J. L. Austin taught us long ago. Famously, John Searle has developed this Austinian insight in an account of the construction of institutional reality. Searle maintains that so-called Status Function Declarations, allegedly having a “double direction of fit”, synchronically create worldly institutional facts, corresponding to the propositional content of the declarations. I argue that Searle’s account of the making of institutional reality is in tension with the special theory of relativity—irrespective of whether the account (...) is interpreted as involving causal generation or non-causal grounding of worldly institutional facts—and should be replaced by a more modest theory which interprets the results of Status Function Declarations in terms of mere Cambridge change and institutional truth. I end the paper by indicating the import of this more modest theory for theorizing about the causal potency of institutional phenomena generated by declarations. (shrink)

This is the second of two volumes of essays in commemoration of Alan Turing; it celebrates his intellectual legacy within the philosophy of mind and cognitive science. A distinguished international cast of contributors focus on the relationship beteen a scientific, computational image of the mind and a common-sense picture of the mind as an inner arena populated by concepts, beliefs, intentions, and qualia. Topics covered include the causal potency of folk- psychological states, the connectionist reconception of learning and (...) concept formation, the understanding of the notion of computation itself, and the relation between philosophical and psychological theories of concepts.

This paper examines the relations between, on the one hand, accounts of the distinction between an agent's identifying with, as opposed to feeling alienated from, their attitudes; and on the other, metaphysical accounts of action. It claims that a commitment to an event-causal conception of agency, which would analyse agency in terms of the causal potency of psychological states and events, appears to render mandatory a particular style of account of identification and alienation – namely, the hierarchical (...) model offered by Harry Frankfurt and Michael Bratman. It is argued that such accounts fall foul of a dilemma: the Authority Problem. The failure of attempts to avoid the Authority Problem is then used to motivate an attractive alternative style of account of the distinction, offered by Richard Moran. However, it is pressed that Moran's account rests on claims about agency which seem incompatible with the event-causal conception of agency. By making the links between the metaphysics of agency and accounts of identification and alienation more explicit, the paper allows us to better comprehend both the apparent need for and characteristic failures of some traditional accounts of identification and alienation, as well as make clear the action-theoretical debt incurred by those who would offer an alternative.

I maintain that dispositions are not causally relevant to their manifestations. The paper begins with a negative argument, which is intended to undermine David Lewis’ recent attempt to restore causal potency to dispositions by identifying their instantiations with the instantiations of their causal bases. I conclude that Lewis’ attempt to vindicate the causal credentials of dispositions meets obstacles that are analogous to those that beset Donald Davidson’s attempt to accord a causal role to the mental. (...) I then consider an argument recently given by Frank Jackson against the causal relevance of dispositions. Jackson’s argument relies on a conception of dispositions that is not likely to be shared by those who defend their causal relevance. I sketch an alternative conception of dispositions that links them more closely to their causal bases, but argue that even on this model dispositions are causally impotent. The paper closes with a defense of the claim that dispositions, in spite of their causal irrelevance to their manifestations, are nevertheless causal-explanatorily relevant to them. (shrink)

Professor Davidson's anomalous monism has been subject to the criticism that, despite advertisements to the contrary, if it were true mental properties would be epiphenomenal. To this Davidson has replied that his critics have misunderstood his views concerning the extensional nature of causal relations and the intensional character of causal explanations. I call this his 'extension reply'. This paper argues that there are two ways to read Davidson's 'extension reply'; one weaker and one stronger. But the dilemma is (...) that: (i) the weak extension reply on its own isn't sufficient to support the principle of the nomological character of causality, (ii) anything strong enough to support that principle under the weak extension reply would be strong enough to warrant the strong extension reply; but (iii) the strong extension reply threatens the very stability of anomalous monism by threatening the causal potency and reality of the mental. For these reasons, I claim that either version of the 'extension reply' is bad news for anomalous monism. I conclude by suggesting that a form of absolute idealism circumvents the very assumptions that generate these kinds of difficulty for committed monists. (shrink)

Following the lead of von Neumann and Wigner, Goswami has developed a paradox-free interpretation of quantum mechanics based on the idealistic notion that consciousness collapes the quantum wave function.

The power to exercise control is a crucial feature of agency. Necessarily, if S cannot exercise some degree of control over anything - any state of affairs, event, process, object, or whatever - S is not an agent. If S is not an agent, S cannot act intentionally, responsibly, or rationally, nor can S possess or exercise free will. In my dissertation I reflect on the nature of control, and on the roles consciousness plays in its exercise. I first consider (...) the fragmented state of philosophical and empirical work on control. I argue that a mature philosophy of agency stands in need of a detailed personal-level account of control, and I begin by explicating a notion I call intentional control. On this explication, an agent J exercises intentional control in service of an intention X to the degree that behavior of J's for which X plays a (non-deviant) causal role approximates the representational content of X. With this explication in hand, I offer analyses of theoretically salient points along a degreed spectrum (covering, e.g., the exercise of minimal, successful, and perfect intentional control). Next, I develop an account of the degrees of intentional control's possession. This involves elucidation of ingredients of intentional control, i.e. those features of agents and environments that constitute an agent's causal potency and skill. It turns out that an agent's possession of control regarding an intention is intimately tied to her ability to repeatedly execute that intention across some specified (hypothetical) set of scenarios. Finally, I discuss a number of potentially fruitful applications of the account. In chapter three I confront a strong intuition, persistent in both philosophy and cognitive science, that consciousness is somehow intimately involved in the exercise of control. In this connection recent empirical work indicates the causal powers of consciousness remain poorly understood. I argue that Functional Agnosticism - the view that any claim regarding a function of consciousness for behavior is currently underdetermined by the data - is the wisest position on the causal powers of consciousness. Recognition of this unsatisfying state of affairs motivates reflection on what might enable progress beyond it. I argue that establishing a causal function for consciousness is facilitated by clarity on several issues. First, what is the sense of consciousness at issue? I isolate state consciousness, discuss the potential relevance of various types of conscious states, and distinguish between ambitious and modest approaches to the causal powers of state consciousness. In short, ambitious approaches seek to understand the causal contributions of a conscious mental state in virtue of the fact that the state is conscious; modest approaches seek to understand the causal contributions of conscious mental states, full stop. I argue that for various theoretical purposes, both approaches can be useful. Second, what is the sense of control at issue? I argue that for many important theoretical purposes, intentional control is the relevant sense. Finally, I illustrate the usefulness of clarity on these issues by examining recent work on the roles of conscious and unconscious vision for action. This work suggests that some important subset of our overt action is controlled by non-conscious processes. I apply insights developed earlier, noting common mistakes made in this literature, and highlighting important empirical possibilities these mistakes obscure. In later chapters I develop a novel account of conscious control. In chapter four I develop a central part of the account, which involves a view on the intentional structure of conscious trying. The leading view entails that conscious trying possesses a descriptive (or thetic) structure. Based on relevant empirical work concerning deafferented and paralyzed patients, I argue for the view that conscious trying is (at least) partially constituted by directive (or telic) structure. Finally, I argue that the exercise of conscious control is best understood as an exercise of intentional control for which the experience of trying plays a constitutive role. After presenting arguments for this view and defending the view against objections, I discuss the importance of conscious control for a mature philosophy of mind and agency. (shrink)

This paper explores the Aristotelian context of the real distinction between existence and essence thought to be posited in Thomas Aquinas’ early workDe Ente Et Essentia. In doing so, the paper situates its own position in the context of contemporary scholarship and in relation to the contemporary trend to downplay Aristotle’s influence in Thomas Aquinas’ philosophy. The paper argues that re-readingDe Ente Et Essentiain this way sheds new light on some of the crucial debates in contemporary Thomist scholarship, particularly with (...) respect to the analogous relation between potency and act: essence and existence, the distinction between conceptual and causal explanation, and the relationship between philosophy and theology in the thought of Thomas Aquinas.

I argue that the best scientific package is anti-Humean in its ontology, but Humean in its laws. This is because potencies and the best system account of laws complement each other surprisingly well. If there are potencies, then the BSA is the most plausible account of the laws of nature. Conversely, if the BSA is the correct theory of laws, then formulating the laws in terms of potencies rather than categorical properties avoids three serious objections: the mismatch objection, the impoverished (...) worlds objection, and the metaphysical 'oomph' objection. I argue that combining anti-Humean properties with Humean laws into a Potency-Best System Account of Laws is a powerful and science-friendly account---something that people on both sides should be able to appreciate.

Vacuum Genesis and Spontaneous Emergence of the Universe from Nothing in Reference to the Classical Notion of Causality and Creation ex nihilo The article discousses philosophical and theological reflections inspired by the cosmological model of the origin of the universe from quantum vacuum through quantum tunneling and the model presented by Hartle and Hawking. In the context of the thesis about the possibility of cosmogenesis ex nihilo without the need of God the creator, the question is being raised concerning the (...) ontological status of nothingness and of the laws of nature in the aforementioned models. After pointing to the fact that they do not imply an absolute nothingness in the philosophical sense, the main objectives of both models and philosophical-theological conclusions they inspire are interpreted in the light of the classical principles of potency and act, theory of causation and chance events in nature, elements of classical theology of creation and the classification of sciences in terms of various levels of abstraction, proposed by Aquinas. Noting the fact that some cosmologists cross methodological boundaries of their science, we emphasize the role and significance of their research in a deeper understanding of the philosophical aspects of the origins of the universe, especially the role of potency in the first stages of its existence and evolution.

The distinction of active potencies into will and nature is one of the most characteristic traits of Duns Scotus’s thought. Scotus distinguishes free and self-determining causality from natural and necessary causality.

High-fidelity cultural transmission, rather than brute intelligence, is the secret of our species’ success, or so many cultural evolutionists claim. It has been selected because it ensures the spread, stability and longevity of beneficial cultural traditions, and it supports cumulative cultural change. To play these roles, however, fidelity must be a causally-efficient property of cultural transmission. This is where the grain problem comes in and challenges the explanatory potency of fidelity. Assessing the degree of fidelity of any episode or (...) mechanism of cultural transmission always depends upon an investigator’s choice of grain of description at which cultural traditions are being studied. The fidelity of cultural transmission then appears to be relative to the granularity at which one approaches cultural variation, and since there is a multiplicity of grains of description by which the same tradition can be studied, there results a multiplicity of measures of fidelity for a same event or mechanism of cultural transmission. If this is correct, because fidelity is always relative to the grain of description dictated by the local and specific research interests of the investigator, then there seems to be no fact of the matter as to whether cultural transmission is faithful or not, independently from a researcher’s framework of analysis. The aims of this paper are to offer a conceptual clarification of the grain problem in cultural evolution, to assess its causes, to unpack its epistemological implications, and to examine its reach and consequences for a science of cultural evolution.

This book presents a radical new picture of natural order. The Newtonian idea of a cosmos ruled by universal and exceptionless laws has been superseded; replaced by a conception of nature as a realm of diverse powers, potencies, and dispositions, a 'dappled world'. There is order in nature, but it is more local, diverse, piecemeal, open, and emergent than Newton imagined. In each chapter expert authors expound the historical context of the idea of laws of nature, and explore the diverse (...) sorts of order actually presupposed by work in physics, biology, and the social sciences. They consider how human freedom might be understood, and explore how Newton's idea of a 'universal designer' might be revised, in this new context. They argue that there is not one unified totalizing program of science, aiming at the completion of one closed causal system. We live in an ordered universe, but we need to rethink the classical idea of the 'laws of nature' in a more dynamic and creatively diverse way. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:A New Look at the Prime MoverDavid BradshawThe last twenty years have seen a notable shift in scholarly views on the Prime Mover. Once widely dismissed as a relic of Aristotle's early Platonism, the Prime Mover is coming increasingly to be seen as a key—perhaps the key—to Aristotle's mature metaphysics and philosophy of mind. Perhaps the best example of the revisionist view is Jonathan Lear's Aristotle: The Desire to (...) Understand. Lear describes Aristotle's position as a form of "objective idealism." It is idealism because Aristotle believes that the fundamental nature of reality conforms to the mind, rather than vice versa; it is objective because the mind to which reality conforms is not that of any particular thinking being, but the divine mind—that is, in a sense, mind itself. "Objects must conform to knowledge, but that does not in the least reveal them to be constituted by any contribution from us... Since, for Aristotle, there is nothing distinctively human about the mind to which objects are conforming, there is no basis for saying that the essences we contemplate are mere appearances."1 Although it may seem strange to think of Aristotle as an idealist, Lear makes a plausible case for his interpretation based on the relevant texts (primarily De Anima III.4 and Metaphysics XII.6-10), and he successfully integrates it into his treatment of other important themes in Aristotle's philosophy.Attempts such as Lear's to tease out the significance of divine thinking are not the only new development afoot. Whereas Lear seems to accept the traditional view that the Prime Mover is a final but not an efficient cause, others such as Thomas de Koninck and Sarah Broadie have challenged that view.2 They have successfully shown, in my opinion, that Aristotle's position requires [End Page 1] that the Prime Mover be in some fashion an efficient cause. But they have not successfully elucidated the nature of this causality, nor have they explained how it is related to the theme rightly given prominence by Lear, the creative character of divine thought.My purpose here is to bring these two strands together—to use an interpretation of divine thinking much like Lear's to illuminate Aristotle's otherwise vexing and obscure remarks about the Prime Mover's causality. Rather than follow the time-honored route of commenting upon the commentators, I will examine the whole issue afresh, working in roughly the order dictated by Aristotle's text. My hope is to present a comprehensive interpretation of the Prime Mover that is more compelling than any yet offered by either the revisionists or their critics.1. Activity and Actuality in Metaphysics XIIMetaphysics XII.6 begins with a terse argument for the existence of a first unmoved mover. In the course of this argument Aristotle drops some important clues about the nature of the Prime Mover and its relation to the cosmos.The argument runs as follows: (1) Time cannot come into being or pass away, for that would involve the paradox of a moment before time or a moment after time. (2) Given Aristotle's own definition of time as "the number of motion in respect of before and after," or any other definition linking time inseparably to motion, motion also cannot come into being or pass away, and so must be continuous. (3) There must be a mover to cause this continuous motion. (4) The mover cannot merely be something capable of causing the motion, but must actively do so (, 1071b17). (5) Even for the mover to act continually is not sufficient if its substance includes potency or is potency (, 1071b18), for then the mover could possibly not be, and so could not guarantee an eternal motion. (6) Therefore the very substance of the mover must be actuality (, 1071b20). In the next sentence Aristotle goes on to speak as if there might be more than one mover, noting that "these substances must be without matter, for they must be eternal, if anything is eternal" (1071b20-22). After this nothing more is said about the possibility of more than one mover until chapter XII.8.There is an... (shrink)

Two major clarifications have greatly abetted the understanding and fruitful expansion of the theory of natural selection in recent years: the acknowledgment that interactors, not replicators, constitute the causal unit of selection; and the recognition that interactors are Darwinian individuals, and that such individuals exist with potency at several levels of organization (genes, organisms, demes, and species in particular), thus engendering a rich hierarchical theory of selection in contrast with Darwin’s own emphasis on the organismic level. But a (...) piece of the argument has been missing, and individuals at levels distinct from organisms have been denied potency (although granted existence within the undeniable logic of the theory), because they do not achieve individuality with the same devices used by organisms and therefore seem weak by comparison. We show here that different features define Darwinian individuality across scales of size and time. In particular, species-individuals may develop few emergent features as direct adaptations. The interactor approach works with emergent fitnesses, not with emergent features; and species, as a consequence of their different mechanism for achieving individuality (reproductive exclusivity among subparts, that is, among organisms), express many effects from other levels. Organisms, by contrast, suppress upwardly cascading effects, because the organismic style of individuality (by functional integration of subparts) does not permit much competition or differential reproduction of parts from within. Species do not suppress the operation of lower levels; such effects therefore become available as exaptations conferring emergent fitness—a primary source of the different strength that species achieve as effective Darwinian individuals in evolution.

In the thought of Duns Scotus, the distinction of active potencies into will and nature takes on a fundamental systematic significance. It distinguishes free and self-determining causality from natural and necessary causality. The purpose of this article is to show to what extent this distinction underlies large parts of Duns Scotus’ moral psychology, ethics, metaphysics and Trinitarian theology.

Aristotle in Aquinas's Theology explores the role of Aristotelian concepts, principles, and themes in Thomas Aquinas's theology. Each chapter investigates the significance of Aquinas's theological reception of Aristotle in a central theological domain: the Trinity, the angels, soul and body, the Mosaic law, grace, charity, justice, contemplation and action, Christ, and the sacraments. In general, the essays focus on the Summa theologiae, but some range more widely in Aquinas's corpus. For some time, it has above all been the influence of (...) Aristotle on Aquinas's philosophy that has been the center of attention. Perhaps in reaction to philosophical neo-Thomism, or perhaps because this Aristotelian influence appears no longer necessary to demonstrate, the role of Aristotle in Aquinas's theology presently receives less theological attention than does Aquinas's use of other authorities, especially in domains outside of theological ethics. Indeed, in some theological circles the influence of Aristotle upon Aquinas's theology is no longer well understood. Readers will encounter here the great Aristotelian themes, such as act and potency, God as pure act, substance and accidents, power and generation, change and motion, fourfold causality, form and matter, hylomorphic anthropology, the structure of intellection, the relationship between knowledge and will, happiness and friendship, habits and virtues, contemplation and action, politics and justice, the best form of government, and private property and the common good. The ten essays in this book engage Aquinas's reception of Aristotle in his theology from a variety of points of view: historical, philosophical, and constructively theological. (shrink)

The article analyzes Aquinas?s arguments for real distinction between essence and being as presented in the chapters 52-54 of the second book of the Summa contra gentiles, in the wider context of his metapyhsics. First, the paper analyzes the determinations of God on the basis of real distinction, and after that it analyzes the role of the act and potency, priority of act, separation of the act from the form in Aquinas?s understanding of esse, as well as the concept (...) of existential participation; in doing so, the difference among those concepts in Plato and Aristotle and in Aquinas is accentuated. At the end, the paper analyzes the role of two kinds of causality, efficient and formal in real distinction. (shrink)

Over time, Aristotle’s theory of four causes lost some of their original flexibility as an instrument to be applied analogically in diverse sciences. Enrico Berti’s distinction between physical and metaphysical causality in Aristotle provides insight into overcoming this crystallization. More importantly, the novelty of Aquinas’ metaphysics of actus essendi calls for a revision of the four causes: first, actus essendi is presented as actuating act and the source of the finite being’s ordered operation; the substantial essence falls to potency (...) and specifies the act of being; the efficient cause is the power of God insofar as he produces and moves the creature; divine exemplar causality is twofold ; the final causality concerns both the order and the governance of the world. In this paper, then, I outline this analogical passage from Aristotle’s physical causality to Aquinas’ metaphysical causality in reference to their modern interpreters, like Enrico Berti and Jan A. Aertsen. (shrink)

While the debate continues over whether Nietzsche’s conception of the will to power is intended as ontology, biology, psychology, or some variant of the three, there is a significant consensus on many sides that were the will to power intended as an ontology, it would be inconsistent with his anti-metaphysical stance, implausible from a contemporary scientific perspective, and very poorly supported, based only on wild metaphysical speculation or sloppy, pseudo-scientific generalization. In this paper, I suggest, to the contrary, that Nietzsche’s (...) published works contain a substantial, though implied, argument for the will to power as ontology. Further, this ontology and the supporting argument for it are fully consistent with a naturalist methodology. Indeed, I will suggest that Nietzsche believes the will to power ontology follows directly from his rejection of metaphysics and is grounded in a critical form of naturalism. Consequently, even if he is mistaken in this conclusion, we must take the will to power ontology as seriously as we do his critique of metaphysics, for it is intended as a direct consequence of that critique. I will further suggest that, once we have recognized Nietzsche’s implied philosophical argument for the will to power ontology, we can better understand the intended scope and purpose of the theory of the will to power, as well as reject many of the influential interpretations of the concept, including the vitalist (Heidegger, Schacht), intentionalist (Clark), evolutionary (Richardson), and teleological (Reginster) readings. In contrast to these interpretations, I argue that the will to power as ontology follows directly from his rejection of three principal metaphysical presumptions: substance, causal agency, and teleology. As a rejection of substance, the will to power describes reality as consisting of general will, not objects, agents, or discrete wills. As a rejection of causal agency, it describes events as maximal manifestations of power rather than as realized potencies—abilities, motives, or possibilities actualized by efficient causal agencies. Finally, as a rejection of teleology, the will to power is a descriptive principle of action and events as essentially active engagements of obstacles, rather than an explanatory final cause, purpose or aim. Consequently, the will to power is a not a theory of desires, intentions, or drives, but rather a basic descriptive principle of events or activity, describing not agency but the causal process as a whole, and tending not toward accumulating power or overcoming resistance, but rather toward the activity of resistance as such. I conclude that the will to power is a critical ontology about what reality is not, rather than a positive theory of reality, intended not to explain events but to reveal and reject the common metaphysical presuppositions that underlie many common-sense, philosophical and scientific explanations of reality, such as freedom of the will, rational and moral motivation, physical atomism and the concept of natural law.

Exciting and important work on the metaphysics of causal powers and dispositions is currently under way. Much of it has been branded as a return to Aristotelian metaphysics, as it seems to put agents and their actions back as ultimate principles of reality. Philosophers involved in this work often speak of a ‘categorical—dispositional’ distinction. And sometimes it is suggested that the distinction is, or is similar to, Aristotle’s distinction between act and potency. The aim of this paper is (...) to assess the legitimacy of that suggestion by explicating both distinctions. I argue that in many recent ‘neo-Aristotelian’ accounts of dispositions a certain idea that lies at the heart of Aristotle’s metaphysics of act and potency is largely absent. This situation is unfortunate, for Aristotle’s idea suggests a surprising relationship between being and power and it flips a certain assumption, still made by many metaphysicians, on its head.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Divine Action and Emergence: An Alternative to Panentheism by Mariuscz Tabaczek, O.P.Edmund LazzariDivine Action and Emergence: An Alternative to Panentheism by Mariuscz Tabaczek O.P., (Notre Dame, IN: University of Notre Dame Press, 2021), xviii + 346 pp.One of the most challenging scientific phenomena for metaphysical explanation is the emergence of higher-order properties out of lower-level constituents of a system. This relatively recent scientific observation raises serious questions for (...) metaphysically reductionist materialism and has inspired a great deal of recent philosophical and theological activity, [End Page 1430] varying greatly in their level of understanding of the scientific phenomenon itself.At the same time, contemporary theological discourse about divine action and the sciences has turned more and more toward panentheism as a way to involve God in the scientific workings of the world without disrupting its operations.Fr. Tabaczek addresses both of these major developments in this volume. For those who do not have the stamina or the interest to dive into his exhaustive analytic treatment of emergence in his previous 2019 volume, Emergence: Towards a New Metaphysics and Philosophy of Science, Fr. Tabaczek provides a detailed summary of his findings in the first two chapters of this volume. Rather than repeat the first volume's detailed consideration of different emergent phenomena, Fr. Tabaczek simply identifies different levels of emergent phenomena in inorganic chemistry, molecular biology, fluid systems, macro-organisms, and evolutionary systems before providing a substantial overview of contemporary philosophical perspectives on emergence.Even in this short overview, however, the reader will find mention and references to the fundamental historical figures in late-nineteenth- and early-twentieth-century Anglophone thought on emergence, often omitted by contemporary literature, such as George Henry Lewis, Samuel Alexander, and C. D. Broad. The rest of the chapter consists in a concise classification and description of contemporary views of emergence, explaining and illuminating issues with downward causation-based accounts, whole-part constraints-based accounts, and supervenience-based accounts before moving on to spend a significant amount of time on Terrence Deacon's dynamical depth account of emergence. While full-length treatments of each account are provided in Emergence, the reader will find herself with more than enough philosophical engagement to understand the different models of emergence and Fr. Tabaczek's explanations of their shortcomings. While also much shorter than in Emergence, Fr. Tabaczek's overview of Deacon's account provides the necessary foundations for his Aristotelian synthesis of hylomorphism and emergence in the second chapter.The second chapter once more provides a review of Emergence, providing a comparison between classical Aristotelian metaphysics and "neo-Aristotelian" metaphysics of disposition. In both the classical- and neo-Aristotelian sections, Fr. Tabaczek shows his competence in chemistry by consistently applying Aristotelian notions of hylomorphic constitution, efficient causality, and final causality to chemical and cellular phenomena. While he criticizes neo-Aristotelianism for its lack of commitment to substantial form, he finds that its dispositionalism grounding act and potency [End Page 1431] provides it with a significant advantage over other models when accounting for emergent phenomena. While not fully endorsing it, Fr. Tabaczek's Aristotelian synthesis answers many of the philosophical questions Deacon addresses in his model.The third and fourth chapters of Divine Action and Emergence introduce a much-needed account of the panentheistic turn in recent theology and science literature. Fr. Tabaczek is especially astute to introduce the history of these accounts after the rigorous and sustained questions of the analytic-philosophical analysis of emergent phenomena. After giving a historical overview of the major figures in panentheism—from German idealism through Alfred North Whitehead and Charles Hartshorne to contemporary theology–science dialogue, Fr. Tabaczek turns his analytic rigor towards dispelling ambiguities in panentheistic claims about God–world relations. Building on the work of Michael Brierley, Fr. Tabaczek argues that the meaning of "en" in panentheism is not a univocal term in the different writings of panentheistic writers, but rather share a Wittgensteinian family resemblance. This disambiguation of the claims of different panentheistic writers throughout history and in theology–science dialogue precedes an overview of the main avenues taken by those writers using emergence in theology–science dialogue before the critical evaluation...

Aquinas thinks that if we want to understand causal interactions between material substances, we cannot focus exclusively on agents and their active powers. In his view, there are also passive potencies which enable material substances to be acted upon. He claims that for every type of active potency, there is a corresponding passive potency. This article aims to clarify Aquinas’s views about the passive potencies of material substances. It recovers his thinking on three key questions: first, what (...) is the basis or source of a material substance’s passive potentialities? Put otherwise, what constituents of material substances explain why they have capabilities for being acted upon? Second, how are a material substance’s passive potencies identified and distinguished from one another? Lastly, are passive potencies for undergoing action the same as a substance’s potencies for existing in determinate ways? For example, is a pot of water’s potentiality for being heated the same as its potentiality to be hot? (shrink)

This book explores the role of Aristotelian concepts, principles, and themes in Thomas Aquinas's theology. Each of the ten essays investigates the significance of Aquinas's theological reception of Aristotle in a central theological domain: the Trinity, the angels, soul and body, the Mosaic law, grace, charity, justice, contemplation and action, Christ, and the sacraments. In general, the essays focus on the Summa theologiae, but some range more widely in Aquinas's corpus. Readers will become acquainted with Aquinas's theological uses of the (...) great Aristotelian themes, such as act and potency, God as pure act, substance and accidents, power and generation, change and motion, fourfold causality, form and matter, hylomorphic anthropology, the structure of intellection, the relationship between knowledge and will, happiness and friendship, habits and virtues, contemplation and action, politics and justice, the best form of government, and private property and the common good.

In Polo’s anthropology, the personal transcendentals constitute the first act of the human being. To achieve an understanding of the contribution to the natural growth of the person of human actions performed in space and time, it is required to investigate how the intensity of this act can increase naturally in the context of the doctrine of act and potency. Review of the constitution of human beings in Aristotle, Aquinas and Polo and the real distinction between their ontological components, (...) together with the concept of instrumental causality served to propose an explanation of the natural growth of the person.

The limitation of act by potency, central in the metaphysics of Thom as Aquinas, has its origins in Plotinus. He transforms Aristotle ’s horizontal causality of change into a vertical causality of participation. Potency and infinity are not just un intelligible lack of limit, but productive power. Form determines matter but is limited by recepti on into matter. The experience of unity begins with sensible things, which always have parts, so what is really one is incorporeal, without division (...) and separation. Unity is like the esse of Thomas, since it is the act that makes a thing what it is and has its fullness in God. (shrink)

THE mind is the locus of various dispositions, of developed sources and motives of action, which are not mere reflex habits but trained abilities and bents, tendencies, liabilities or inhibitions. Human knowing is more an intending of facts or states of affairs than a relation to them. Knowledge is not a predicamental relation. Consciousness is related to its object not as North Pole to South Pole, nor as container to contained, but as matter to form, and to the physical form (...) of the object of consciousness there corresponds the intentional form of the consciousness itself. To know reality is not to acquire it, grasp it, have it, possess it, contemplate it or dwell in it; it is to be informed by it i.e. intentionally to become it. Knowledge is the form rather than the cause of rational behaviour: technique, method, knack, skill, expertise, know-how, flair, strategic sense, prudence, taste, discretion, caution, judiciousness, decorum, conscientiousness, style, discipline, sagacity, discrimination, wisdom, respect for sense. Such principles operate not by description of nor prescription for, but by incarnation in and information of performance. It is, for instance, man’s respect for sense that is the form of a logically clear expression, and ideas are skills in the use of words. This human capacity and achievement is an intentional becoming, an actuation of the subject, bringing him to act. Yet, properly speaking, it is not action but passion. For knowing is an effect of which reality is the cause, and this causality is not a relation: actio est in passo—not in the agent, nor between the agent and the patient, but in the patient as from the agent, an actuation of the subject in dependence on the object. Of course it may be argued that non datur actio in distans, but far from requiring some intellectual ether, this only means that action and passion are not candidates for the application of spatial or temporal predicates. The known need not be close to the knower. True knowledge is the form of our reason when it is truly about matters of fact. It is not, then, a relation between subject and object, but a knowledge of states of affairs or facts constituted by interrelated objects which, to be known, must comprise some states of affairs of whose constituent objects some, at least, are knowing subjects. Inquiry is related to insight as searching to finding, or as trying to succeeding. Knowing is the second act or actualization of the intellect Thomists regard as second potency, first act, or accidental passive potency. But knowing is not a transitive activity. It is an achievement of intention, not an episode. It is a capacity, disposition, proneness or inclination, in so far as it connotes the abiding possibility of its contents’ polymorphic propositional and non-propositional expression in rational behaviour, which is an effect of knowing as an achievement, though it is also rightly said to be informed by know-how rather than caused by it. The act of self-knowledge consciously intends the self, but the self is intended as known and not as conscious. Thus, though true of consciousness, the distinction between consciously judging and consciously being tickled is not in consciousness but in knowledge of consciousness. Knowledge should be studied not in its products, but in its various expressions, especially in linguistic ones. For words and sentences are the most easily inspected class of things that we think in.

The chapter shows that Scotus defends the view that ‘God exists’ is both metaphysically and logically necessary. Thus, Scotus maintains that denying that God exists involves asserting a contradiction, and that this can be shown to be the case. But while Scotus believes that it can be shown that there is a concept in virtue of which ‘God exists’ is self-evident, he also believes that human beings in the current run of things can have no access to the content of (...) this concept. The chapter also relates the claims that God is both metaphysically and logically necessary to the kind of causally dependent modalities that Scotus employs in his attempt to prove God’s existence.

In 1997 an international conference on Aristotle and modern science took place in Thessaloniki. Aristotle’s view of nature—his criticism of the atomists, on the one hand, and modern science, on the other—seem to be widely opposed, but in recent years science has changed so much that scientists resort to certain basic notions of Aristotle’s natural philosophy to underpin their theories and make material nature more intelligible. In a first paper Hilary Putnam argues against Victor Gaston that Aristotle’s theory of cognition (...) is a “ direct realism” and not as many say a theory based on representation. Perception and thinking are in direct contact with things and their properties. In a charming comparison Bas C. van Fraassen argues that both tragedy and science are subspecies of representation. As in poetry, in science the inexplicable is kept off stage. John P. Anton is confident that the revival of Aristotle’s model of science can provide a solution to the question of the unity of the various sciences. He levels a stinging attack at Putnam’s interpretation of Aristotle’s theory of cognition. Lambros Couloubaritsis voices amazement that in Physics IV Aristotle says nothing about the creative capacity of time, but believes that the notion of “appropriate time” will bring this out. James R. Brown argues that the main stream of science stemming from the seventeenth century is a fusion of the Platonic and mechanic traditions, but that in recent years Aristotle has made an impressive comeback. He examines to what extent the notion of potentiality may be in agreement with and help explain certain physical facts perceived by common sense observation, although it does no justice to quantum “ bizarreness”. He sees better help in the Platonic account of formal causality. Speaking about levels of reality Basarab Nicolescu believes that the universe is self-creating, showing an open structure. A flow of information traverses the various levels of reality. The notion of potency, we are told by Ephtichios Bitsakis, exercises quite some attraction on scientists. Indeed, Aristotle is a precursor of scientific realism, but his theories are marred by many inconsistencies: the Prime Mover, final causality, and entelechy contradict his dynamic view of nature and should be abandoned. In the transformation of massive particles into nonmassive ones the actual mass becomes potential. Thomas M. Olshewsky points out that Aristotle has a differentiated notion of prime matter and rejects absolute prime matter. Jagdish Hattiangadi suggests giving up the idea of substance. Demetra Sfendoni-Mentzou also tackles “the always actual question” of what matter is for Aristotle. Nowadays the idea of stable particles has disappeared and we have to deal with what is potentially real. (shrink)

This is a text book for an introductory course combining metaphysics and natural theology. It deals with the nature of metaphysical knowledge, act and potency, pure existence, becoming and causality, as well as the problems of natural theology like the demonstration of the existence of God, His attributes, and activity. The problems are so placed that God appears at every step of metaphysics as the first and Supreme Being, the pure act and first cause of all things.—J. K.

Let us call a property that is essentially dispositional a potency.1 David Armstrong thinks that potencies do not exist. All sparse properties are essentially categorical, where sparse properties are the explanatory properties of the type science seeks to discover. An alternative view, but not the only one, is that all sparse properties are potencies or supervene upon them. In this paper I shall consider the differences between these views, in particular the objections Armstrong raises against potencies.
