Causation and Laws

In this paper I offer an alternative to the standard, mechanistic/fatalistic account of causal necessity, one compatible with the existence of laws of nature but not deterministic in the way this is usually understood.

At its core this book is concerned with logic and computation with respect to the mathematical characterization of sentient biophysical structure and its behavior. -/- Three related theories are presented: The first of these provides an explanation of how sentient individuals come to be in the world. The second describes how these individuals operate. And the third proposes a method for reasoning about the behavior of individuals in groups. -/- These theories are based upon a new explanation of experience in (...) nature, the construction of senses, and motile behavior. This new approach is developed from first principles to enable a rigorous and systematic explanation of the variety of associated intelligent behaviors. -/- Alongside this development is a further account that focuses upon the nature of our work. It discusses the existential aspects of scientific inquiry, its epistemology and logic. It seeks to clarify the nature of the mathematical characterization and computation of natural behaviors, dealing with questions in the foundations of logic. It explores methodological issues related to reduction and the refinement of ideas from intuition to formal logical structure. -/- In support of this inquiry we work toward the development of a calculus for biophysical construction and its dynamics. If successful this mechanics mathematically characterizes sensory and motile behavior. -/- Upon this foundation we propose a model of apprehension and explore how its products are processed by the organism. Finally, we develop a probabilistic theory that enables us to reason about inaccessible factors in group behavior. -/- The mechanics we propose suggests the design and physical realization of a new model of computation; one in which structure and the concurrency of action are a first-order consideration. -/- We identify opportunities for experimental verification of the theory and we suggest a proof of our results in practice by the identification of this mechanism, allowing the construction of machines that experience.

If the laws are deterministic, then standard theories of counterfactuals are forced to reject at least one of the following conditionals: 1) had you chosen differently, there would not have been a violation of the laws of nature; and 2) had you chosen differently, the initial conditions of the universe would not have been different. On the relevant readings---where we hold fixed factors causally independent of your choice---both of these conditionals appear true. And rejecting either one leads to trouble for (...) philosophical theories which rely upon counterfactual conditionals---like, for instance, causal decision theory. Here, I outline a semantics for counterfactual conditionals which allows us to accept both (1) and (2). And I discuss how this semantics deals with objections to causal decision theory from Arif Ahmed. (shrink)

In this paper we discuss how Causal Decision Theory should be modified to handle a class of problematic cases involving deterministic laws. Causal Decision Theory, as it stands, is problematically biased against your endorsing deterministic propositions (for example it tells you to deny Newtonian physics, regardless of how confident you are of its truth). Our response is that this is not a problem for Causal Decision Theory per se, but arises because of the standard method for assessing the truth of (...) certain counterfactuals. The truth of deterministic laws is `modally fragile' on the standard semantics for counterfactuals: if determinism is true and you were to do otherwise, the laws would be different. We provide two ways of avoiding this problem: 1) supplement the standard semantics for counterfactuals with impossible worlds, or 2) introduce rigid designators into the description of problematic decision situations. We argue that both of these approaches are well-motivated and can be readily incorporated into Lewisian Causal Decision Theory. (shrink)

Mental causation, idea that it is us – via our minds – who cause bodily actions is as commonsensical as it is indispensable for our understanding of ourselves as rational agents. Somewhat less uncontroversial, but nonetheless widespread (at least among ordinary people) is the idea that the mind is non-physical, following the intuition that what is physical can neither act nor think nor judge morally. Taken together, and cast into a metaphysical thesis, the two intuitions yield interactive dualism: the view (...) that human persons and their minds are non-physical but can nonetheless interact with their bodies, most notably through their brains. This thesis has two main objectives: first, to defend interactive dualism against objections, and second, to show how it can blend in with a physical world in which laws of nature hold. The first part (chapter 1) consists in a brief motivation of interactive dualism as opposed to non-interactive dualism. I argue that non-interactive, epiphenomenalist dualism sacrifices so many crucial aspects of our human existence that interactive dualism is highly to be preferred to it, barring even stronger counterarguments against the latter. It is those putative counterarguments I address in parts II and III. Part II takes on the philosophical objections from the causal closure of the physical and from causal heterogeneity. The former takes the success of physics and physiology as basis for the doctrine of the causal closure of the physical (CCP). I argue against this that there is not only no convincing argument for CCP, but also that any science-based belief in CCP cannot be epistemically justified. As regards the causal heterogeneity objection, it is ‘weighed and found wanting’, because it relies on unwarranted assumptions about causation. In part III, I examine the objection from energy conservation. It roughly says that if interactive dualism were true, then energy would not be conserved, which physics taught us cannot be the case. My reply is that the underlying conception of energy (and momentum) conservation is wrong-headed and not the one that actual physicists use. Instead of being categorical and global, conservation laws are conditional and local, thereby making natural room for mental interaction. Some dualists, however, have sought to make interactive dualism conservation-friendly, notably by invoking quantum physics; I show that these attempts are unnecessary and create more problems than they solve. Finally, in chapter 9, I turn the tables on non-interactionists by investigating current neurophysiological literature on volitional actions, which, though not addressing the question directly, still encourages the interactive dualist picture more than a non-interactionist one. Part IV is about the interplay between interactive dualism and the laws of nature. The ultimate goal is, if possible, to come up with a theory of the laws of nature that explains the lawlike behavior of nature and at the same time makes room for interaction. I begin by pointing out that the laws of nature are or at least should be what physicalists worry about (chapter 10). I then proceed with a historical survey on the development of the notion of laws of nature (chapter 11) that sheds light on its theistic origin. This is followed by an inquiry into the question how a law of nature could possibly be broken (chapter 12) and a survey of the extant metaphysical theories of the laws of nature with special regard to their receptivity to interaction (chapter 13). Finally, in chapter 14 I develop a theory of the laws of nature both faithful to their divine origin and the possibility of mental interaction: dispositionalist divine decretalism, a synthesis of dispositionalism and Jeffrey Koperski’s divine decretalism.

Anscombe’s 1971 inaugural lecture at Cambridge, entitled ‘Causality and Determination’, has had a lasting influence on a remarkably broad range of philosophers and philosophical debates, touching on fundamental topics in philosophy of science, action theory, the free will debate, epistemology, philosophy of mind, and metaphysics. Especially where anti-reductionist or pluralist strands of philosophical thought are being seriously considered, one should not be surprised to find references to Anscombe’s lecture. Moreover, there appears to be a growing interest in Anscombe’s comprehensive philosophical (...) outlook, as attested by the recent publication of a weighty collection of essays spanning that outlook in its full breadth in the prestigious Routledge Philosophical Minds series. Against this background it is apt that now, 50 years after the original lecture, a Topical Collection sees the light, circling around the most central themes from Anscombe’s lecture, with a particular emphasis on the question how these hang together, how they form part of the larger philosophical project that Anscombe obviously intended the lecture to highlight. This Introduction motivates the Topical Collection, and introduces the various contributions against that background. (shrink)

Powers ontologies are currently enjoying a resurgence. This would be dispiriting news for the moderns; in their eyes, to imbue bodies with powers is to slide back into the scholastic slime from which they helped philosophy crawl. I focus on Descartes’s ‘little souls’ argument, which points to a genuine and, I think persisting, defect in powers theories. The problem is that an Aristotelian power is intrinsic to whatever has it. Once this move is accepted, it becomes very hard to see (...) how humble matter could have such a thing. It is as if each empowered object were possessed of a little soul that directs it and governs its behavior. Instead of attempting to resurrect the Aristotelian power theory, contemporary philosophers would be best served by taking their inspiration from its early modern replacement, devised by John Locke and Robert Boyle. On this view, powers are internal relations, not monadic properties intrinsic to their bearers. This move at once drains away the mysterious directedness of Aristotelian powers and solves the contemporary version of the little souls argument, Neil Williams’s ‘problem of fit.’. (shrink)

In this article, I discuss Richard Swinburne’s case for the conception of substance causation, identified with the substances-powers-liabilities account of causation, versus the conception of event causation, identified with alternative accounts. I specify the place of Swinburne’s argument in the debates about agent causation, and uncover reasons to be sceptical about the claims that substance causation is a genuine alternative to event causation, and that it helps to comprehend the specifics of the causation involved in free agency. I also advance (...) considerations in favour of the relations-between-universals account of causation that can make it preferable to the SPL account. (shrink)

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 question of the metaphysical status of the laws of physics has received increased attention in recent years. Perhaps most well-known among this work are David Lewis’s Humean supervenience and Nancy Cartwright’s dispositionalism, both of which reject the classical conception of the laws of physics as necessary and real independent of the objects they govern, arguing instead that what we call laws are shorthand for the regularities of local states of affairs or the dispositions of objects. The properties of necessity (...) and reality are generally taken to go hand-in-hand when physical laws are concerned; however, this leaves aside the possibility that the laws of physics are independently real yet contingent. This paper will explore this third option which is found in the work of Quentin Meillassoux. We will ask: if laws both exist independent of their objects and are contingent, what happens when laws change? Specifically, the possibility of metaphysical retro-causation becomes a live option. This raises both questions of the ontological status of the past as well as our epistemic access to the past after a change in physical laws. Meillassoux’s ontology of hyper-chaos weathers this challenge with its consistency intact; however, it is an open question of whether or not saving the reality of physical laws by sacrificing their necessity is worth the epistemic limits and metaphysical strangeness that it implies.

Dispositionalism is the view that causal powers are among the irreducible properties of nature. It has long been among the core competing positions in the metaphysics of laws, but its potential implications for other key debates within metaphysics and the philosophy of science have remained under-explored. Travis Dumsday fills this major gap in the literature by establishing new connections between dispositionalism and such topics as substance ontology, ontic structural realism, material composition, emergentism, natural-kind essentialism, perdurantism, time travel, and spacetime substantivalism. (...) He also puts forward a novel view concerning the precise relationship between causal powers and the fundamental laws of nature. His rich and accessible study will appeal to readers interested in contemporary analytic metaphysics and philosophy of science. (shrink)

In this chapter we examine the relation between mechanisms and laws/counterfactuals by revisiting the main notions of mechanism found in the literature. We distinguish between two different conceptions of ‘mechanism’: mechanisms-of underlie or constitute a causal process; mechanisms-for are complex systems that function so as to produce a certain behavior. According to some mechanists, a mechanism fulfills both of these roles simultaneously. The main argument of the chapter is that there is an asymmetrical dependence between both kinds of mechanisms and (...) laws/counterfactuals: while some laws and counterfactuals must be taken as primitive (non-mechanistic) facts of the world, all mechanisms depend on laws/counterfactuals.

[full article, abstract in English; abstract in Lithuanian] Armstrong’s theory of laws and causation may be articulated as something like the following, which we may refer to as the received view: “Laws are intrinsic higher-order relations of ensuring between properties. The instantiation of laws is identical with singular causation. This identity is a posteriori.” Opponents and advocates of this view, believe that it may fairly and correctly be attributed to Armstrong. I do not deny it; instead I seek to reconsider (...) the received view, specifically by treating it as a part of Armstrong’s metaphysics. The main features that should concern us are truthmaker theory and the formal account of the constitutive parts of states of affairs. I also discuss Bird’s ultimate argument against Armstrong and show how its impact is weakened by this proper reading. (shrink)

This article presents a critical analysis of two influential readings of Kant’s Second Analogy, namely, Gerd Buchdahl’s “modest reading” and Michael Friedman’s “strong reading.” After pointing out the textual and philosophical problems with each, I advance an alternative reading of the Second Analogy argument. On my reading, the Second Analogy argument proves the existence of necessary and strictly universal causal laws. This, however, does not guarantee that Kant has a solution for the problem of induction. After I explain why the (...) empirical lawfulness of nature does not guarantee the empirical uniformity of nature, I examine the modal status of empirical laws in Kant and argue contra Buchdahl and Friedman that empirical laws express two different kinds of necessity that are not reducible to each other. -/- .

This paper defends an invariance-based account of laws of nature: Laws are generalizations that remain invariant under various sorts of changes. Alternatively, laws are generalizations that exhibit a certain kind of independence from background conditions.

Newton began his Principia with three Axiomata sive Leges Motus. We offer an interpretation of Newton’s dual label and investigate two tensions inherent in his account of laws. The first arises from the juxtaposition of Newton’s confidence in the certainty of his laws and his commitment to their variability and contingency. The second arises because Newton ascribes fundamental status both to the laws and to the bodies and forces they govern. We argue the first is resolvable, but the second is (...) not. However, the second tension shows that Newton conceives laws as formal causes of bodies and forces. This neo-Aristotelian conception goes missing in Kantian accounts of laws, as well as accounts that stress laws’ grounding in powers and capacities. (shrink)

Sober and Elgin defend the claim that there are a priori causal laws in biology. Lange and Rosenberg take issue with this on Humean grounds, among others. I will argue that Sober and Elgin don’t go far enough – there are a priori causal laws in many sciences. Furthermore, I will argue that this thesis is compatible with a Humean metaphysics and an empiricist epistemology.

Our ordinary causal concept seems to fit poorly with how our best physics describes the world. We think of causation as a time-asymmetric dependence relation between relatively local events. Yet fundamental physics describes the world in terms of dynamical laws that are, possible small exceptions aside, time symmetric and that relate global time slices. My goal in this paper is to show why we are successful at using local, time-asymmetric models in causal explanations despite this apparent mismatch with fundamental physics. (...) In particular, I will argue that there is an important connection between time asymmetry and locality, namely: understanding the locality of our causal models is the key to understanding why the physical time asymmetries in our universe give rise to time asymmetry in causal explanation. My theory thus provides a unified account of why causation is local and time asymmetric and thereby enables a reply to Russell’s famous attack on causation. (shrink)

Metaphysics and science have a long but troubled relationship. In the twentieth century the Logical Positivists argued metaphysics was irrelevant and that philosophy should be guided by science. However, metaphysics and science attempt to answer many of the same, fundamental questions: What are laws of nature? What is causation? What are natural kinds? -/- In this book, Markus Schrenk examines and explains the central questions and problems in the metaphysics of science. He reviews the development of the field from the (...) early modern period through to the latest research, systematically assessing key topics including -/- dispositions, counterfactual conditionals, laws of nature, causation, natural kinds, essence, necessity. -/- With the addition of chapter summaries and annotated further reading, Metaphysics of Science is a much-needed, clear and informative survey of this exciting area of philosophical research. It is essential reading for students and scholars of philosophy of science and metaphysics. (shrink)

This text is a review of Joseph Urbas's Emerson's Metaphysics: A Song of Laws and Causes (Lexington Books, 2016). In this book, Urbas proposes a reconstruction of the metaphysics of the American poet, essayist, and self-defined philosopher Ralph Waldo Emerson. According to Urbas, Emerson has a coherent metaphysics, the fundamental principle of which is the category of causation. Reacting to David Hume, Emerson would have deliberately emphasized causation, connection, relation, tie, link, and so on. Emerson is thus characterized as a (...) "causationist" and his philosophy is considered a "causationism." Urbas also argues — against other prevalent interpretations — that Emerson's philosophy is part of the New England "ontological turn" and that it is best understood as a "metaphysical realism" of both particulars and universals alike. I examine these lines of argumentation and propose a couple of critical remarks concerning Emerson's relations to Goethe and Francis Ellingwood Abbot. (shrink)

Scientific explanation, laws of nature and causation are crucial and frontier issues in the philosophy of science. This book studies the complex relationship between the three concepts, aiming to achieve a holistic synthesis about explanation–laws–causation. By reviewing Hempel's Scientific Explanation models and Salmon's three conceptions – the epistemic, modal and ontic conception – the book suggests that laws are essential to explanation and our understanding of laws will help solve the problems of the latter. Concerning the nature of laws, this (...) book tackles both the problems of regularity approach and necessitarian approach. It also proposes that the ontological order of explanation should be from events to causation, then to regularity, and finally to science system, but the epistemological order should be from science system to laws to explanation and causation. In addition, this book examines the legitimacy of Ceteris Paribus laws, the connection between explanation and reduction, the relation between explanation and interpretation, and some other issues closely related to explanation–laws–causation. This book will attract scholars and students of philosophy of science, philosophy of nature, cognitive science, etc. (shrink)

Standard philosophical accounts attempt to understand physical modality either in terms of special metaphysical entities and relationships or in terms of the organization of non-modal information, as in Best Systems Analysis. This paper defends an alternative to both these approaches in which invariance and various independence conditions play a central role. The methodological importance of separating law-claims from claims about initial and boundary conditions is highlighted.

This book gives the first complete, fully historicized account of Emerson's metaphysics of cause and effect and its foundational position in his philosophy as a whole. Joseph Urbas proposes an intellectual biography of Emerson the metaphysician but also the life-story of a concept synonymous, in the Transcendentalist period, with life itself—the story of the principle at the origin of all being and change.

How can the laws of nature, that determine how objects behave, be understood as natural objects themselves? The answer that transpires from the analysis of modern theories of the laws of nature is: laws of nature are due to the causal structure of our world. They express the causal efficiacy of fundamental properties of nature. In contrast to rivaling theories, this answer does justice to the fact that laws of nature determine the course of natural events without having to appeal (...) to the strong assumption of necessarily acting forces. The modal force exerted by the laws of nature instead reflects a fundamental factual constitution of our world: fundamental properties like charge or mass exert their efficiacy in an unperturbed fashion, without influencing each other. The 'necessity' that laws of nature convey is hence compatible with their metaphysical contingency, the possibility of other, nomologically different worlds. The suggested theory connects laws of nature and causality in a new way: only in a temporally asymmetrical world can causality exist, and only in a causal world can fundamental properties exhibit those asymmetric relations that we call laws of nature.

La metafísica de la Superveniencia Humeana ha sido atacada por dos alternativas explícitamente anti-Humeanas: el Realismo Nómico y el Esencialismo Disposicional. Cada una de estas alternativas ofrece una explicación ontológica de la actual distribución de instanciaciones de primer orden. Ambas sostienen, contra el Humeano, que esta distribución no es un accidente metafísico. En este artículo argumento que las explicaciones ofrecidas por ellas son ilusorias. -/- The metaphysics of Humean Supervenience has been attacked by two explicitly anti-Humean alternatives: Nomic Realism and (...) Dispositional Essentialism. Each one of these alternatives offers an ontological explanation of the actual distribution of first-order instantiations. They both claim, against the Humean, that this distribution is not a metaphysical accident. In this paper, I argue that the explanations offered by them are illusory. (shrink)

Many commentators have argued that Locke understood laws of nature as causally efficacious. On this view the laws are causally responsible for the production of natural phenomena. This paper argues that this interpretation faces serious difficulties. First, I argue that it will be very difficult to specify the ontological status of these laws. Proponents of the view suggest that these laws are divine volitions. But I argue that this will be difficult or impossible to square with Locke’s nominalism. Second, I (...) argue that it will be difficult to specify the manner in which these laws operate. The view runs the risk of collapsing into occasionalism and Locke has measured critiques of the occasionalist position. The only way to maintain that laws are causally efficacious divine volitions while avoiding occasionalism is to have God engage in what I call ‘brute fact-making’. But brute fact-making is difficult to square with Locke’s remarks on God’s action in the world and with his standards for explanation in natural philosophy. (shrink)

The thesis that in social sciences causal explanations are possible only in terms o mechanisms due to the lack of genuine laws has been increasingly popular among social scientist and philosophers. In this article it is examined whether the explanation by mechanism is necessarily an explanation without laws or, on the contrary, it can involve some kind o laws. To this end it is argued, firstly, that mechanisms are not always the antonym of law insofar as they express propensities and (...) so tendencies; secondly, that these tendencies ar causal and entail capacities and dispositions; thirdly, that capacities and dispositions involve in human behaviour have to face the problem of free will; and finally, reasons are offered i favor of considering causal tendencies as authentic laws. The ultimate aim of this article is to demonstrate that explanation of social facts can involve well-established laws in its explanans although they are not universal laws. (shrink)

The problem of explanatory non-symmetries provides the strongest reason to abandon the view that laws can figure in explanations without causal underpinnings. I argue that this problem can be overcome. The solution that I propose starts from noticing the importance of conditions of application when laws do explanatory work, and I go on to develop a notion of nomological dependence that can tackle the non-symmetry problem. The strategy is to show how a strong notion of counterfactual dependence as guaranteed by (...) the laws is a plausible account of what we aim towards when we give law-based explanations. The aim of this project is not to deny that causal relations can do explanatory work but to restore laws of nature as capable of being explanatory even in the absence of any knowledge of causal underpinnings.

In this work, I analyze our concept of cause in the face of criticism of Bertrand Russell in his article “On the Notion of Cause”. For Russell, there is an estrangement between the notion of cause and mature science of physics. The word cause (and its correlates) would not be used in physics, thus eliminating the main justification of philosophy for his job—the foundation of science. Thus, the various causal notions and the principle of causality should be abandoned by philosophers (...) as something outdated. The aim of this study is to assess the extent to which our notion of cause, with its asymmetric nature, can be explained by physics and investigate the question of the existence of causes in our world. (shrink)

Bertrand Russell famously argued that causation is not part of the fundamental physical description of the world, describing the notion of cause as “a relic of a bygone age”. This paper assesses one of Russell’s arguments for this conclusion: the ‘Directionality Argument’, which holds that the time symmetry of fundamental physics is inconsistent with the time asymmetry of causation. We claim that the coherence and success of the Directionality Argument crucially depends on the proper interpretation of the ‘ time symmetry’ (...) of fundamental physics as it appears in the argument, and offer two alternative interpretations. We argue that: if ‘ time symmetry’ is understood as the time -reversal invariance of physical theories, then the crucial premise of the Directionality Argument should be rejected; and if ‘ time symmetry’ is understood as the temporally bidirectional nomic dependence relations of physical laws, then the crucial premise of the Directionality Argument is far more plausible. We defend the second reading as continuous with Russell’s writings, and consider the consequences of the bidirectionality of nomic dependence relations in physics for the metaphysics of causation. (shrink)

The paper argues against the widely accepted assumption that the causal laws of (completed) physics, in contrast to those of the special sciences, are essentially strict. This claim played an important role already in debates about the anomalousness of the mental, and it currently experiences a renaissance in various discussions about mental causation, projectability of special science laws, and the nature of physical laws. By illustrating the distinction with some paradigmatic physical laws, the paper demonstrates that only law schemata are (...) strict whereas causal laws are generally non-strict. Several potential replies to this argument are discussed and rejected as unsound. (shrink)

Fred Dretske, Michael Tooley, and David Armstrong accept a theory of governing laws of nature according to which laws are atomic states of affairs that necessitate corresponding natural regularities. Some philosophers object to the Dretske/Tooley/Armstrong theory on the grounds that there is no illuminating account of the necessary connection between governing law and natural regularity. In response, Michael Tooley has provided a reductive account of this necessary connection in his book Causation (1987). In this essay, I discuss an improved version (...) of his account and argue that it fails. First, the account cannot be extended to explain the necessary connection between certain sorts of laws—namely, probabilistic laws and laws relating structural universals—and their corresponding regularities. Second, Tooley’s account succeeds only by (very subtly) incorporating primitive necessity elsewhere, so the problem of avoiding primitive necessity is merely relocated. (shrink)

Moritz Schlick dealt with the question of causality in various places, including in his Allgemeine Erkenntnislehre - but especially in two essays that appeared in the journal Die Naturwissenschaften in 1920 and 1931. I will deal here with the essay "Naturphilosophische Betrachtungen über das Kausalprinzip" from 1920. First, in the first section, I will present the historical context and thus the problems to which Schlick was responding. In the second and third sections, I will reconstruct and discuss Schlick's proposed solutions (...) to these problems. (shrink)

The key idea of the interventionist account of causation is that a variable A causes a variable B if and only if B would change if A were manipulated in the appropriate way. This paper raises two problems for Woodward's (2003) version of interventionism. The first is that the conditions it imposes are not sufficient for causation, because these conditions are also satisfied by non-causal relations of nomological dependence expressed in association laws. Such laws ground a relation of mutual manipulability (...) that is incompatible with the asymmetry of causation. Several ways of defending the interventionist account are examined and found unsatisfying. The second problem is that it often seems to be impossible, in a model that contains variables linked by an association law, to satisfy the conditions imposed on interventions on such variables. Various ways to solve this second problem, most importantly the analysis of manipulability in terms of difference making, are examined. Given that none solves the problem, I conclude that the interventionist conditions are neither sufficient nor necessary for causation. It is suggested that they provide an analysis of nomological dependence, which may be supplemented with the notion of a causal process to yield an analysis of causation. (shrink)

I provide a comprehensive metaphysics of causation based on the idea that fundamentally things are governed by the laws of physics, and that derivatively difference-making can be assessed in terms of what fundamental laws of physics imply for hypothesized events. Highlights include a general philosophical methodology, the fundamental/derivative distinction, and my mature account of causal asymmetry.

This chapter explores some issues having to do with the structure of the evidential reasoning we use to infer causal and lawful claims. It is argued that such reasoning always makes use of prior, causally, or nomologically committed information, thus undercutting various views that attempt to reduce causal and lawful claims to claims about regularities. A non-reductive account of laws and causes built around the notion of invariance is advanced as an alternative.

A scientific mathematical law is causal if and only if it is a process law that contains a time derivative. This is the intrinsic criterion for causal laws we propose. A process is a space-time line along which some properties are conserved or vary. A process law contains a time variable, but only process laws that contain a time derivative are causal laws. An effect is identified with what corresponds to a time derivative of some property or magnitude in a (...) process law, whereas the other terms correspond to the cause(s). According to our criterion, causes are simultaneous with their effects and causality has no temporal direction. Several examples from natural and social disciplines support the applicability of our criterion to all scientific laws. Various objections to our proposal are presented and refuted. The merits our intrinsic theory of causality vis-à-vis the Salmon?Dowe conserved quantity theory are discussed. (shrink)

I give two arguments for the claim that all events which occur at the actual world and are such that they could be caused, are also such that they must actually be caused. The first argument is an improvement of a similar argument advanced by Alexander Pruss, which I show to be invalid. It uses Pruss’s Brouwer Analog for counterfactual logic, and, as a consequence, implies inconsistency with Lewis’s semantics for counterfactuals. While (I suggest) this consequence may not be objectionable, (...) the argument founders on the fact that Pruss’s Brouwer Analog has a clear counterexample. I thus turn to a second, “Lewisian” argument, which requires only an affirmation of one element of Lewis’s analysis of causation and one other, fairly weak possibility claim about the nature of wholly contingent events. The final section of the paper explains how both arguments escape objections from supposed indeterminacy in quantum physics. (shrink)

Leuridan (2010) argued that mechanisms cannot provide a genuine alternative to laws of nature as a model of explanation in the sciences, and advocates Mitchell’s (1997) pragmatic account of laws. I first demonstrate that Leuridan gets the order of priority wrong between mechanisms, regularity, and laws, and then make some clarifying remarks about how laws and mechanisms relate to regularities. Mechanisms are not an explanatory alternative to regularities; they are an alternative to laws. The existence of stable regularities in nature (...) is necessary for either model of explanation: regularities are what laws describe and what mechanisms explain. (shrink)
