This essay argues that current theories of action fail to explain agentive control because they have left out a psychological capacity central to control: attention. This makes it impossible to give a complete account of the mental antecedents that generate action. By investigating attention, and in particular the intention-attention nexus, we can characterize the functional role of intention in an illuminating way, explicate agentive control so that we have a uniform explanation of basic cases of causal deviance in action as (...) well as other defects of agency, explain cases of skilled agency and sharpen questions about the role of thought in agency. This provides for a different orientation in the theory of action. (shrink)

In his 'The Disorder of Things' John Dupré presents an objection to reductionism which I call the 'anti-essentialist objection': it is that reductionism requires essentialism, and essentialism is false. I unpack the objection and assess its cogency. Once the objection is clearly in view, it is likely to appeal to those who think conceptual analysis a bankrupt project. I offer on behalf of the reductionist two strategies for responding, one which seeks to rehabilitate conceptual analysis and one (more concessive) which (...) avoids commitment to any such analysis.

SummaryMany contemporary philosophers of language believe that realist metaphysics and a beha‐viouristic approach to language are incompatible, debate centring on which is to be given up. In this paper I argue that no incompatibility has been shown to exist. In the first section I attempt to give both a characterization of, and an argument for, behaviourism. Then I attempt to characterize realism more generally than is often done, evaluating the work of Dummett, Quine, Putnam and Wittgenstein, as recently interpreted, in (...) that light. Finally I attempt to sketch a behaviouristic justification of classical predicate logic and offer some programmatic remarks on behaviouristic accounts of mathematics and natural science.RésuméBien des philosophes contemporains du langage, estimant qu'une métaphysique réaliste et une approche behavioriste sont incompatibles, centrent le débat sur la question «lequel des deux doit‐il être sacrifité?» Je montre dans ce papier qu'on n'a jamais pu prouver l'existence d'une incompatibilité. Dans la première partie, je tente de caractériser et de défendre le behaviorisme. Puis j'essaie de caractériser le réalisme plus généralement que cela n'a été souvent fait et évalue dans cette perspective les oeuvres de Dummett, de Quine, de Putnam et de Wittgenstein à la lumière de leurs interprétations récentes. Finalement, je propose une justification behavioriste de la classique logique des prédicats et quelques remarques programmatiques quant à une approche behavioriste des mathématiques et des sciences naturelles.ZusammenfassungManche zeitgenössische Philosophen glauben, dass eine realistische Metaphysik nicht mit einer behavioristischen Betrachtungsweise der Sprache vereinbar sei, wobei sich der Streit um die Frage dreht, welche der beiden Haltungen aufgegeben werden müsse. Ich argurnentiere, dass die Unvereinbarkeit nicht wirklich nachgewiesen wurde. Im ersten Abschnitt versuche ich, den Beha‐viorismus genauer zu charakterisieren und zu seinen Gunsten zu argumentieren. Ich versuche dann, eine allgemeinere Charakterisierung des Realismus zu geben, als das üblich ist, indem ich die Werke von Dummett, Quine, Putnam und Wittgenstein, wie sie neuerdings unter diesen Gesichts‐punkt interpretiert werden, beurteile. lch versuche schliesslich, eine behavioristische Rechtferti‐gung der klassischen Prädikatenlogik zu skizzieren, und lege auch einige programmatische Bemerkungen zur behavioristischen Behandlung von Mathematik und Naturwissenschaft vor.

What exactly is reasoning? Like many other philosophers, I shall endorse a broadly causal conception of reasoning. Reasoning is a causal process, in which one mental event (say, one’s accepting the conclusion of a certain argument) is caused by an antecedent mental event (say, one’s considering the premises of the argument). Just like causal accounts of action and causal accounts of perception, causal accounts of reasoning have to confront a version of what has come to be known as the problem (...) of deviant causal chains. In this paper, I shall propose an account of the nature of reasoning, incorporating a solution to the specific version of the deviant causal chains problem that arises for accounts of reasoning. One striking feature of my solution is that it requires that certain normative facts are causally efficacious. It might be thought that this feature will make my account incompatible with any plausibly naturalistic approach to understanding the mind. I shall argue that this is not so: my account of the nature of reasoning is quite compatible with plausible versions of naturalism. (shrink)

According to an increasing number of authors, the best, if not the only, argument in favour of physicalism is the so-called 'overdetermination argument'. This argument, if sound, establishes that all the entities that enter into causal interactions with the physical world are physical. One key premise in the overdetermination argument is the principle of the causal closure of the physical world, said to be supported by contemporary physics. In this paper, I examine various ways in which physics may support the (...) principle, either as a methodological guide or as depending on some other laws and principles of physics. (shrink)

It is widely thought that there is an important argument to be made that starts with premises taken from the science of physics and ends with the conclusion of physicalism. The standard view is that this argument takes the form of a causal argument for physicalism. Roughly, physics tells us that the physical realm is causally complete, and so minds (among other entities) must be physical if they are to interact with the world as we think they do. In what (...) follows, I raise problems for this view. After an initial review of the causal argument, I begin my case by showing that the totality of physical truths do not deductively entail the causal completeness of the physical realm, using a double-prevention scenario and causation by omission to show that nonphysical causes of physical effects would not need to violate physical conservation laws. I then move on to raise problems for an inductive argument for causal completeness by drawing on the neo-Russellian view that there is no causation in fundamental physics, and so causation must itself be a realized or derived entity. I conclude by suggesting that the underlying problem is that the causal argument has fallen out of touch with the sophisticated understanding that philosophers have developed of the role of causation within physics.

Examples involving common causes — most prominently, examples involving genetically influenced choices — are analytically equivalent not to standard Newcomb Problems — in which the Predictor genuinely predicts the agent's decision — but to non-standard Newcomb Problems — in which the Predictor guarantees the truth of her predictions by interfering with the agent's decision to make the agent choose as it was predicted she would. When properly qualified, causal and epistemic decision theories diverge only on standard — not on non-standard (...) — Newcomb Problems, and thus not on examples involving common causes. (shrink)

The paper attempts to explicate and justify the position I call `Agency Incompatibilism'- that is to say, the view that agency itself is incompatible with determinism. The most important part of this task is the characterisation of the conception of agency on which the position depends; for unless this is understood, the rationale for the position is likely to be missed. The paper accordingly proceeds by setting out the orthodox philosophical position concerning what it takes for agency to exist, before (...) going on to explain why and how that orthodoxy should be challenged. The relations between my own views and those of others writing on the issues of free will and moral responsibility, in three crucial and inter-connected areas are then explored. These are (1) the question how animals should figure in the philosophy of action; (2) the question what the lesson is of `Frankfurt-style' examples; and (3) the distinction between so-called `leeway' incompatibilism and `source' incompatibilism. The paper moves on to consider and respond to various objections to Agency Incompatibilism, including the claim that to embrace the conception of agency that makes incompatibilism plausible is to beg the question against the compatibilist, and also the worry that determinism is an empirical thesis which ought not to be straightforwardly falsifiable by such a priori reasoning as Agency Incompatibilism appears to involve. I also try to rebut the worry that Agency Incompatibilism is committed to the existence of an unintelligible and/or naturalistically impossible variety of irreducible agent causation. (shrink)

In this paper I aim to make sense of our pre‐theoretic intuitions about dispositions by presenting an argument for the identity of a disposition with its putative categorical base. The various possible ontologies for dispositions are outlined. The possibility of an empirical proof of identity is dismissed. Instead an a priori argument for identity is adapted from arguments in the philosophy of mind. I argue that dispositions occupy, by analytic necessity, the same causal roles that categorical bases occupy contingently and (...) that properties with identical causal roles are identical. The validity of the argument depends upon the possibility of overdetermination of disposition manifestations being rejected. ‘Ungrounded dispositions’ are dismissed as not genuine dispositions. Identity conditions for dispositions and categorical bases are outlined. (shrink)

Intellectualists hold that knowledge-how is a species of knowledge-that, and consequently that the knowledge involved in skill is propositional. In support of this view, the intentional action argument holds that since skills manifest in intentional action and since intentional action necessarily depends on propositional knowledge, skills necessarily depend on propositional knowledge. We challenge this argument, and suggest that instructive representations, as opposed to propositional attitudes, can better account for an agent’s reasons for action. While a propositional-causal theory of action, according (...) to which intentional action must be causally produced “in the right way” by an agent’s proposition-involving reasons, has long held sway, we draw on Elizabeth Anscombe’s insights offer a path toward an alternative theory of action. In so doing, we reject the implicitly Cartesian conception of knowledge at the core of the intentional action argument, while hanging on to the idea that mental states are representations of a certain kind. Our argument provides theoretical support for anti-intellectualism by equipping philosophers with an account of non-propositional, practical content. (shrink)

This chapter contains sections titled: Reductionist Accounts of Teleology Non ‐ Reductionist Accounts Prospects and Consequences References.

Most contemporary philosophers of action agree on the following claims. Firstly, the possibility of deviant or wayward causal chains poses a serious problem for the standard-causal theory of action. Secondly, we can distinguish between different kinds of deviant causal chains in the theory of action. In particular, we can distinguish between cases of basic and cases of consequential deviance. Thirdly, the problem of consequential deviance admits of a fairly straightforward solution, whereas the possibility of basic deviance constitutes a separate and (...) difficult problem that requires its own solution. I will argue that the problem of basic deviance is no more troublesome than the problem of consequential deviance, as a solution to the former is implicit in the standard solution to the latter.

In Russell's Problems of Philosophy (PP), acquaintance is the basis of thought and also the basis of empirical knowledge. Thought is based on acquaintance, in that a thinker has to be acquainted with the basic constituents of his thoughts. Empirical knowledge is based on acquaintance, in that acquaintance is involved in perception, and perception is the ultimate source of all empirical knowledge.

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

The category of sympathy marks a number of basic divisions in early modern approaches to action explanations, whether for human agency or for change in the wider natural world. Some authors were critical of using sympathy to explain change. They call such principles “unintelligible” or assume they involve “mysterious” action at a distance. Others, including Margaret Cavendish, Anne Conway, and Gottfried Wilhelm Leibniz, appeal to sympathy to capture natural phenomena, or to supply a backbone to their metaphysics. Here I discuss (...) how concerns about sympathetic actions form at least a partial background for differing seventeenth-century conceptions of what it is to explain action. I argue that critics of sympathy generally insist on an “atomistic” approach to action explanation, which makes primitively relational phenomena come out as problematic. Proponents of sympathy, by contrast, allow for a more holistic approach to action explanation, which allows for such basic connections. Hence, divergent attitudes toward sympathetic action in part explain differences in approaches to explanation. I conclude by showing how some of these core concerns fade into the background when in the eighteenth-century sympathy gets psychologised and individualised. (shrink)

The paper argues that mental causation can be explained from the sufficiency of counterfactual dependence for causation together with relatively weak assumptions about the metaphysics of mind. If a physical event counterfactually depends on an earlier physical event, it also counterfactually depends on, and hence is caused by, a mental event that correlates with (or supervenes on) this earlier physical event, provided that this correlation (or supervenience) is sufficiently modally robust. This account of mental causation is consistent with the overdetermination (...) of physical events by mental events and other physical events, but does not entail it. (shrink)

Jennifer Hornsby's account of human action frees us from the temptation to think of the person who acts as 'doing' the events that are her actions, and thereby removes much of the allure of 'agent causation'. But her account is spoiled by the claim that physical actions are 'tryings' that cause bodily movements. It would be better to think of physical actions and bodily movements as identical; but Hornsby refuses to do this, seemingly because she thinks that to do so (...) would be to endorse the so-called 'standard causal story'. But Hornsby misses a possibility here, for we can insist on this identity claim without endorsing the standard story if we embrace an account which parallels the disjunctive account in the philosophy of perception. This will leave us with a picture of physical action that saves the insights of Hornsby's account without succumbing to its distortions. (shrink)

Many philosophers accept some version of a principle that says for all x, if x exists, then x plays a unique causal role. After briefly clarifying one version of the principle in Section 1, Section 2 gives reasons to doubt it by showing that there are non-identical “causal indiscernibles”—I call them “married causes.” Section 3 then sketches a few philosophical puzzles for which married causes may be helpful.

ABSTRACT The goal of this paper is to find out if Michael Smith's version of the causal theory of action is able to solve David Velleman's agency par excellence challenge. Smith has claimed that his theory can deal with the challenge insofar as the exercise of the capacity to be instrumentally rational plays the intermediating role which Velleman thinks of the agent as playing in the causation of action. However, I argue Smith misunderstands the challenge at hand, thereby failing to (...) find the agent's proper role in action explanation. Moreover, I claim Velleman's objection puts Smith's account of the causal theory in trouble by showing it cannot reconcile the causal explanation of intentional action with our ordinary conception of agency. If Smith intends to explain what a 'full-blooded' intentional action is, I then believe he needs to incorporate into his theory a more robust account of rational guidance. Resumo: O objetivo deste artigo é descobrir se a versão da teoria causal da ação de Michael Smith é capaz de resolver o desafio da agência por excelência de David Velleman. Smith tem sustentado que sua teoria pode lidar com o desafio na medida em que o exercício da capacidade de ser instrumentalmente racional desempenha o papel que Velleman imagina que o agente desempenhe na causação da ação. Contudo, argumento que Smith não compreende corretamente o desafio em questão, falhando desse modo em encontrar o papel adequado do agente na explicação da ação. Além disso, defendo que a objeção de Velleman põe a abordagem da teoria causal de Smith em apuros ao mostrar que ela não é capaz de reconciliar a explicação causal da ação intencional com nossa concepção ordinária de agência. Se Smith pretende explicar o que uma ação intencional 'plena' é, então acredito que ele precisa incorporar em sua teoria uma abordagem mais robusta de orientação racional. (shrink)

In what sense does empty space feature in visual experience? In the first part of this essay I sketch a view advanced by Soteriou and Richardson on which one's visual awareness of empty space is explained by appeal to ‘structural’ features of the phenomenology of visual experience, in particular the phenomenology of experiencing one's visual field as bounded. I suggest that although this ‘structuralist’ view is silent on whether empty space has a phenomenal appearance, the very appeal to structural features (...) seems a natural foil to some such thought. In the second part, I outline a view on which it can be granted that empty space does, after all, have a phenomenal appearance and, so, is not best cast as a species of absence perception as the structuralist avows, at least on a certain construal of ‘absence perception’. After O'Shaughnessy , I contend that although some privations have a phenomenal appearance, ‘absence perception’ should single out the putative perception of phenomena that lack phenomenal reality. I finally consider how the descriptive phenomenology that the structuralist points to, and which I urge should be embraced, can nonetheless be reconciled with the view I spell out. (shrink)

One thousand stones, suitably arranged, might form a heap. If we remove a single stone from a heap of stones we still have a heap; at no point will the removal of just one stone make sufficient difference to transform a heap into something which is not a heap. But, if this is so, we still have a heap, even when we have removed the last stone composing our original structure. So runs the Sorites paradox. Similar paradoxes can be constructed (...) with any predicate which, like 'heap', displays borderline vagueness. Although I have frequently heard it said that there is no completely credible and satisfying dissolution of the paradoxes of the Sorites family; and although there is no possible approach to dissolution which has not been at least partially explored, philosophers continue glibly to use vague language as though it were entirely unproblematic. Since no argument has ever been produced which would justify our ignoring the para~doxes, this situation is extremely unsatisfactory. (shrink)

A brain-computer interface designed to restore motor function detects neural activity related to intended movement and thereby enables a person to control an external device, for example, a robotic limb, or even their own body. It would seem legitimate, therefore, to describe a BCI as a system that translates thought into action. This paper argues that present BCI-mediated behavior fails to meet the conditions of intentional physical action as proposed by causal and non-causal theories of action. First, according to the (...) causal theory of action physical actions are bodily movements that are causally related to a person’s intentions. It can be argued, however, that the proximate cause of action in present BCI-mediated behavior is not the person’s intention, and that the behavior fails to meet the conditions of reliability, sensitivity and difference-making. Second, BCI-mediated behavior can be accommodated by a Volitionist account of action if we can equate imagining movement with trying to move. The argument presented is that the novelty, and limited functionality and sensory feedback of present BCIs challenges this equation. (shrink)

The literature on physicalism often fails to elucidate, I think, what the word physical in physical ism precisely means. Philosophers speak at times of an ideal set of fundamental physical facts, or they stipulate that physical means non-mental , such that all fundamental physical facts are fundamental facts pertaining to the non-mental. In this article, I will probe physicalism in the very much tangible framework of quantum mechanics. Although this theory, unlike “ideal physics” or some “final theory of non-mentality”, is (...) an incomplete theory of the world, I believe this analysis will be of value, if for nothing else, at least for bringing some taste of physical reality, as it were, back to the debate. First, I will introduce a broad characterization of the physicalist credo. In Sect. 2, I will provide a rather quick review of quantum mechanics and some of its current interpretations. In Sect. 3, the notion of quantum non-separability will be analyzed, which will facilitate a discussion of the wave function ontology in Sect. 4. In Sects. 5 and 6, I will explore competing views on the implications of this ontology. In Sect. 7, I will argue that the prior results, based on a thoroughly realist interpretation of quantum mechanics, support only a weak version of non-reductive physicalism. (shrink)

The basic form of the exclusion problem is by now very, very familiar. 2 Start with the claim that the physical realm is causally complete: every physical thing that happens has a sufficient physical cause. Add in the claim that the mental and the physical are distinct. Toss in some claims about overdetermination, give it a stir, and voilá—suddenly it looks as though the mental never causes anything, at least nothing physical. As it is often put, the physical does all (...) the work, and there is nothing left for the mental to do. (shrink)

Surprisingly little attention has been paid to the nature of conscious control. As a result, experiments suggesting that we lack conscious control over our actions cannot be properly evaluated. Joshua Shepherd (2015; 2021) aims to fill this gap. His proposal is grounded in the standard causalist account of action, according to which, simply put, bodily movements are controlled by the agent if and only if they are caused, in the right way, by the relevant psychological states. In this paper, I (...) argue that the proposal does not succeed in distinguishing between mere causation and actual control; it does not solve the problem of deviant causation. On the basis of my criticism, Anscombean action theory promises to offer a valuable perspective. It suggests that an important function of consciousness is to integrate an action into a rational whole. If this is on the right track, it supports Shepherd’s overall claim that the importance of consciousness for action control is often underestimated, because this contribution of consciousness may often go unnoticed in experimental settings.

In this article, I examine recent debates concerning the existence and the nature of basic actions. The discussion is structured around four theses, with which Arthur Danto introduced basic actions to contemporary theorists. The theses concern (i) the relationship between agency and causality, (ii) the distinction between basic and complex actions, (iii) the regress argument for basic actions, and (iv) the structure of practical knowledge in the light of these actions.

In very general terms, an agent is a being with the capacity to act, and 'agency' denotes the exercise or manifestation of this capacity. The philosophy of action provides us with a standard conception and a standard theory of action. The former construes action in terms of intentionality, the latter explains the intentionality of action in terms of causation by the agent’s mental states and events. From this, we obtain a standard conception and a standard theory of agency. There are (...) alternative conceptions of agency, and it has been argued that the standard theory fails to capture agency. Further, it seems that genuine agency can be exhibited by beings that are not capable of intentional action, and it has been argued that agency can and should be explained without reference to causally efficacious mental states and events. Debates about the nature of agency have flourished over the past few decades in philosophy and in other areas of research. In philosophy, the nature of agency is an important issue in the philosophy of mind, the philosophy of psychology, the debates on free will and moral responsibility, in ethics, meta-ethics, and in the debates on the nature of reasons and practical rationality. For the most part, this entry focuses on conceptual and metaphysical questions concerning the nature of agency. In the final sections, it provides an overview of empirically informed accounts of the sense of agency and of various empirical challenges to the commonsense assumption that our reasons and our conscious intentions make a real difference to how we act.

In this dissertation, I develop and defend a model of causation that allows for dualist mental causation in worlds where the physical domain is physically complete. In Part I, I present the dualist ontology that will be assumed throughout the thesis and identify two challenges for models of mental causation within such an ontology: the exclusion worry and the common cause worry. I also argue that a proper response to these challenges requires a thoroughly lightweight account of causation, i.e. an (...) account that allows for causes to be metaphysically distinct from the phenomena that produce or physically necessitate their effects. In Part II, I critically evaluate contemporary responses to these challenges from the philosophical literature. In particular, I discuss List and Stoljar’s criticism of exclusion worries, Kroedel’s alternative dualist ontology, concerns about the notion of causal sufficiency, and Lowe’s models of dualist mental causation. I argue that none of these proposals provide independent motivation for a thoroughly lightweight account of causation and therefore leave room for improvement. In the first four chapters of Part III, I develop a thoroughly lightweight model of causation, which builds on interventionist approaches to causation. First, I explain how so-called ‘holding fixed’-requirements in standard interventionist accounts stand in the way of dualist mental causation. I then argue that interventionist accounts should impose a robustness condition on causal correlations and that, with this condition in place, the ‘holding fixed’-requirements can be weakened such that they do allow for dualist mental causation. I dub the interventionist model with such weakened ‘holding fixed’-requirements ‘insensitive interventionism’, argue that it can counter the exclusion worry as well as the common cause worry, and explain under which circumstances it would predict there to be dualist mental causation. Importantly, these circumstances might, for all we know, hold in the actual world. In the final three chapters of Part III, I defend insensitive interventionism against some objections. I consider the objection that causation must be productive, the objection that causes must physically necessitate their effects, and the objection that insensitive interventionism is too permissive. I respond by drawing from the literature on causation by absences and on the relation between causation and fundamental physics. Overall, insensitive interventionism performs as well as standard interventionist accounts. I conclude that insensitive interventionism is a credible model of causation. (shrink)

Plausibly, agents act freely iff their actions are responses to reasons. But what sort of relationship between reason and action is required for the action to count as a response? The overwhelmingly dominant answer to this question is modalist. It holds that responses are actions that share a modally robust or secure relationship with the relevant reasons. This thesis offers a new alternative answer. It argues that responses are actions that can be explained by reasons in the right way. This (...) explanationist answer comes apart from the modalist answer. For it holds that actions are responses to reasons if they are explained by those reasons even if they don’t share a modally robust relationship. Explanationism thus offers a novel way of vindicating the intuition that alternative possibilities don’t matter to responding to reasons and (consequently) free agency. The key dialectical position the thesis develops is that both modalism and explanationism constitute attempts to capture he core type of relationship encoded by the notion of a response. Responses to reasons, at core, involve a non-accidental relationship between reason and action. We can either understand non-accidentality as a modal phenomenon – as a modally robust tracking between two facts. Or we can understand non-accidentality as an explanatory phenomenon – as a special explanatory relationship between two facts. According to my rival explanationist proposal, two facts share a non-accidental relationship iff we can give a unified explanation of why both obtain. Unified explanations are explanations of why [p&q] that cannot be decomposed into two (or more) separate independent explanations of p and of q. Consequently, according to explanationism about responding to reasons, actions are responses to reasons iff those reasons offer a rational explanation of the action that cannot be decomposed into separate independent components.

On a causal theory of rational behavior, behavior is just a causal consequence of the reasons an actor has. One of the difficulties with this theory has been the possibility of the "wayward causal chains," according to which reasons can cause the expected output, but in such an unusual way that the output is clearly not intentional. The inability to find a general way of excluding these wayward chains without implicitly appealing to elements incompatible with a pure causal account (like (...) brute acts of will) has been a problem for the causal theory. This essay attempts to find a general solution to the problem. The solution rests on the premise that behavior-producing systems are goal-directed, and that on a purely causal analysis of goal-directedness it can be shown that the wayward chains' resulting in the goal is purely fortuitous because these chains do not subserve the function of the system.
