Materialist metaphysicians want to side with physics, but not to take sides within physics.Ifwetook literally the claim of a materialist that his position is simply belief in the claim that all is matter, as currently conceived, we would be faced with an insoluble mystery. For how would such a materialist know how to retrench when his favorite scientific hypotheses fail? How did the 18thcentury materialist know that gravity, or forces in general, were material? How did they know in the 19thcentury (...) that the electromagnetic field was material, and persisted in this conviction after the aether had been sent packing?The doctrine of physicalism casts a long shadow in contemporary philosophy, configuring all kinds of philosophical issues and projects. Unsurprisingly, its proponents argue that physicalism has all the obvious features necessary for a scientific hypothesis to be in what we will call ‘good standing,’ i.e. being worthy of serious scientific investigation. In fact, many claim much more, arguing that physicalism is a well-confirmed hypothesis and possibly amongst the best of our theories. But, as our second opening passage makes clear, a persistent worry has been that physicalism, or ‘materialism’ as van Fraassen terms it, is an edifice built on sand. For many philosophers question whether the ‘physical’ can be specified at all, or at least in a manner that will produce a physicalism that would be in good standing. (shrink)

This paper is an investigation into what could be a goodexplication of ``theory S is reducible to theory T''''. Ipresent an axiomatic approach to reducibility, which is developedmetamathematically and used to evaluate most of the definitionsof ``reducible'''' found in the relevant literature. Among these,relative interpretability turns out to be most convincing as ageneral reducibility concept, proof-theoreticalreducibility being its only serious competitor left. Thisrelation is analyzed in some detail, both from the point of viewof the reducibility axioms and of modal logic.

Qualia and Physicalism. It is assumed that the following three relations exhaust the possibilities for a physicalist account of qualia: 1. determination, 2. identity, 3. realization. The first relation is immediately rejected because it does not exclude property dualism. The second faces the problem that it is probably impossible to discriminate empirically between the identity thesis and the epiphenomenalist position. The third cannot handle qualia adequately, for qualia are not functional properties and the realization relation is only plausible as a (...) relation between physical realizers and functional properties. Finally, if one attempts to replace multiple realization by multiple identities it is shown that the notion of multiple property identities is unintelligible. The upshot is that if these three relations exhaust the possibilities of a physicalist construal of qualia then physicalism is wrong. (shrink)

Several leading topics outstanding after John Earman's Bayes or Bust? are investigated further, with emphasis on the relevance of Bayesian explication in epistemology of science, despite certain limitations. (1) Dutch Book arguments are reformulated so that their independence from utility and preference in epistemic contexts is evident. (2) The Bayesian analysis of the Quine-Duhem problem is pursued; the phenomenon of a "protective belt" of auxiliary statements around reasonably successful theories is explicated. (3) The Bayesian approach to understanding the superiority of (...) variety of evidence is pursued; a recent challenge (by Wayne) is converted into a positive result on behalf of the Bayesian analysis, potentially with far-reaching consequences. (4) The condition for applying the merger-of-opinion results and the thesis of underdetermination of theories are compared, revealing significant limitations in applicability of the former. (5) Implications concerning "diachronic Dutch Book" arguments and "non-Bayesian shifts" are drawn, highlighting the incompleteness, but not incorrectness, of Bayesian analysis. (shrink)

Substance dualism is widely rejected by philosophers of mind, but many continue to accept some form of property dualism. The assumption here is that one can consistently believe that (1) mental properties are not physical properties, while denying that (2) mental particulars are not physical particulars. But is this assumption true? This paper considers several analyses of what makes something a physical particular (as opposed to a non-physical particular), and it is argued that on any plausible analysis, accepting (1) requires (...) accepting (2) as well.

How should physical entities be characterized? Physicalists, who have most to do with the notion, usually characterize the physical by reference to two components: 1. The physical entities are the entities treated by fundamental physics with the proviso that 2. Physical entities are not fundamentally mental (that is, do not individually possess or bestow mentality) Here I explore the extent to which the appeals to fundamental physics and to the NFM (“no fundamental mentality”) constraint are appropriate for characterizing the physical, (...) especially for purposes of formulating physicalism. Ultimately, I motivate and defend a version of an account incorporating both components: The physics-based NFM account: An entity existing at a world w is physical iff (i) it is treated, approximately accurately, by current or future (in the limit of inquiry, ideal) versions of fundamental physics at w, and (ii) it is not fundamentally mental (that is, does not individually either possess or bestow mentality).

The present work is focussed on the completeness of physics, or what is here called the Completeness Thesis: the claim that the domain of the physical is causally closed. Two major questions are tackled: How best is the Completeness Thesis to be formulated? What can be said in defence of the Completeness Thesis? My principal conclusions are that the Completeness Thesis can be coherently formulated, and that the evidence in favour if it significantly outweighs that against it. In opposition to (...) those who argue that formulation is impossible because no account of what is to count as physical can be provided, I argue that as long as the purpose of the argument in which the account is to be used are borne in mind there are no significant difficulties. The account of the physical which I develop holds as physical whatever is needed to fix the likelihood of pre-theoretically given physical effects, and hypothesises in addition that no chemical, biological or psychological factors will be needed in this way. The thus formulated Completeness Thesis is coherent, and has significant empirical content. In opposition to those who defend the doctrine of emergentism by means of philosophical arguments I contend that those arguments are flawed, setting up misleading dichotomies between needlessly attenuated alternatives and assuming the truth of what is to be proved. Against those who defend emergentism by appeal to the evidence, I argue that the history of science since the nineteenth century shows clearly that the empirical credentials of the view that the world is causally closed at the level of a small number of purely physical forces and types of energy is stronger than ever, and the credentials of emergentism correspondingly weaker. In opposition to those who argue that difficulties with reductionism point to the implausibility of the Completeness Thesis I argue that completeness in no way entails the kinds of reductionism which give rise to the difficulties in question. I argue further that the truth of the Completeness Thesis is in fact compatible with a great deal of taxonomic disorder and the impossibility of any general reduction of non-fundamental descriptions to fundamental ones. In opposition to those who argue that the epistemological credentials of fundamental physical laws are poor, and that those laws should in fact be seen as false, I contend that truth preserving accounts of fundamental laws can be developed. Developing such an account, I test it by considering cases of the composition of forces and causes, where what takes place is different to what is predicted by reference to any single law, and argue that viewing laws as tendencies allows their truth to be preserved, and sense to be made of both the experimental discovery of laws, and the fact that composition enables accurate prediction in at least some cases.

To earn the title “ontological physicalist,” one must endorse an entailment thesis of the following sort: the physical properties that are had, together with the causal laws, determine which higher-level properties are had. I argue that if this thesis is to capture all that is essential to physicalist intuitions, the relevant set of causal laws must be restricted to purely physical laws. But then it follows that higher-level properties are physical properties. The conclusion is that one cannot consistently be an (...) ontological physicalist while endorsing property pluralism.

Paul Churchland argues that the continuity of human intellectual development provides evidence against folk psychology and traditional epistemology, since these latter find purchase only at the later stages of intellectual development. He supports this contention with an analogy from the history of thermodynamics. Careful attention to the thermodynamics analogy shows that the argument from continuity does not provide independent support for eliminative materialism. The argument also rests upon claims about continuity which do not support the claim that the continuity of (...) intellectual development is evidence for the elimination of folk psychology. Traditional epistemology and folk psychology should not yet be abandoned. (shrink)

There is no problem more paradigmatically philosophical than the mind-body problem. Nevertheless, I will argue that the problem is empirical. I am not even suggesting that conceptual analysis of the various mind-body theories be abandoned – just as I could not suggest it be abandoned for theories in physics or biology. But unlike the question, ‘Is every even number greater than 2 equal to the sum of two primes?’ the mind-body problem cannot be solved a priori, by analysis alone; though (...) I will not argue this thesis here, it is nearly obvious, since purported solutions must make matter of fact claims, heavy with existential import, about the real world. By contrast, an investigation of the sensitivity of the mind-body problem to empirical evidence will show that purported solutions to the problem are empirically testable, to a degree consistent with philosophy giving a clarified mind-body problem to the sciences. I offer the bold outlines of such an investigation here. (shrink)

In the recent methodological individualism-holism debate on explanation, there has been considerable focus on what reasons methodological holists may advance in support of their position. We believe it is useful to approach the other direction and ask what considerations methodological individualists may in fact offer in favor of their view about explanation. This is the background for the question we pursue in this paper: Why be a methodological individualist? We start out by introducing the methodological individualism-holism debate while distinguishing two (...) forms of methodological individualism: a form that says that individualist explanations are always better than holist accounts and a form that says that providing intervening individualist mechanisms always makes for better explanations than purely holist ones. Next, we consider four lines of reasoning in support of methodological individualism: arguments from causation, from explanatory depth, from agency, and from normativity. We argue that none of them offer convincing reasons in support of the two explanatory versions of individualism we consider. While there may well be occasions in which individualists’ favorite explanations are superior, we find no reason to think this always must be the case. (shrink)

The physicalist thesis that all entities are nothing over and above physical entities is often interpreted as appealing to a supervenience-based account of "nothing over and aboveness”, where, schematically, the A-entities are nothing over and above the B-entities if the A-entities supervene on the B-entities. The main approaches to filling in this schema correspond to different ways of characterizing the modal strength, the supervenience base, or the supervenience connection at issue. I consider each approach in turn, and argue that the (...) resulting formulation of physicalism is compatible with physicalism’s best traditional rival: a naturalist emergentism. Others have argued that supervenience-based formulations of physicalism fail. My aim here, besides addressing the full spectrum of supervenience-based approaches, is to show how certain philosophical and scientific theses concerning naturalism, properties, and laws give us new reasons to think that supervenience-based formulations of physicalism are untenable.

Some claim that Non- reductive Physicalism is an unstable position, on grounds that NRP either collapses into reductive physicalism, or expands into emergentism of a robust or ‘strong’ variety. I argue that this claim is unfounded, by attention to the notion of a degree of freedom—roughly, an independent parameter needed to characterize an entity as being in a state functionally relevant to its law-governed properties and behavior. I start by distinguishing three relations that may hold between the degrees of freedom (...) needed to characterize certain special science entities, and those needed to characterize their composing physical entities; these correspond to what I call ‘reductions’, ‘restrictions’, and ‘eliminations’ in degrees of freedom. I then argue that eliminations in degrees of freedom, in particular—when strictly fewer degrees of freedom are required to characterize certain special science entities than are required to characterize their composing physical entities—provide a basis for making sense of how certain special science entities can be both physically acceptable and ontologically irreducible to physical entities.

In the first section of this paper, I articulate Jaegwon Kim's argument against emergent down ward causation. In the second section, I canvas four responses to Kim's argument and argue that each fails. In the third section, I show that emergent downward causation does not, contra Kim, entail overdetermination. I argue that supervenience of emergent upon base properties is not sufficient for nomological causal relationsbetween emergent and base properties. What sustains Kim's argument is rather the claim that emergent properties realized (...) by base properties can have no causal powers distinct from those base properties. I argue that this is false.

I here defend microphysical manyism. According to microphysical manyism, each composite or higher-level object is a mere plurality of microphysical particles. After clarifying the commitments of the view, I offer two physicalist-friendly arguments in its favour. The first argument appeals to the Canberra Plan. Here I argue that microphysical particles acting in unison play the theoretical roles associated with composite objects - that they do everything that we think of composite objects as doing - and thus that composite objects are (...) to be identified with pluralities of microphysical particles. Along the way I rebut the objections that pluralities of particles don’t display the right emergent, ‘lingering’, or modal properties to be good candidates for identification with higher-level objects. In the second argument I claim that microphysical manyism is uniquely able to capture a compelling and widespread physicalist intuition concerning the intimate nature of the relationship between higher-level, composite objects and the microphysical world.

The realization relation that allegedly holds between mental and physical properties plays a crucial role for so-called 'non-reductive physicalism' because it is supposed to secure both the ontological autonomy of mental properties and their ability to make a causal difference to the course of the causally closed physical world. For a long time however, the nature of the realization relation has largely been ignored in the philosophy of mind. It has only been a couple of years since accounts were proposed (...) according to which realization is understood against the background of the so-called 'causal theory of properties'. At least partially, the hope was to solve the problem of mental causation, in particular the kind of causal exclusion reasoning made famous by Jaegwon Kim, in a way acceptable to non-reductive physicalists. The paper asks whether a proper explication of the realization relation can indeed help explain how physically realized mental properties can be causally efficacious in the causally closed physical world and argues for a negative answer.

I hope to show that supervenience and determination, as I have here intuitively characterized them, are really different expressions of the same core idea which one may make more precise in a great number of different ways, depending on the interpretation one puts on the catchall parameters “cases”, “truth of kind P”and “truth of kind S”.

In what sense are the special sciences autonomous of fundamental physics? Autonomy is an enduring theme in discussions of the relationship between the special sciences and fundamental physics or, more generally, between higher and lower-level facts. Discussion of ‘autonomy’ often fails to recognise that autonomy admits of degrees; consequently, autonomy is either taken to require full independence, or risk relegation to mere apparent autonomy. In addition, the definition of autonomy used by Fodor, the most famous proponent of the autonomy of (...) the special sciences, has been robustly criticised by Loewer. In this paper I develop a new account of autonomy following Woodward which I dub ‘generalised autonomy’ since it unifies dynamical, causal and nomic autonomy. Autonomy, on this account, can be partial: some lower-level details matter while others do not. To summarise: whilst the detailed lower level is unconditionally relevant, conditionalising on the higher-level facts renders some lower-level details irrelevant. The macrodependencies that the higher-level facts enter into — be they dynamical, causal or nomic — screen off the underlying microdetails. This account helps resolve an explanatory puzzle: if the lower-level facts in some way underpin the higher-level facts, why don’t the lower-level details matter more for the day-to-day practice of the special sciences? The answer will be: the facts uncovered by the special sciences are autonomous in my sense, and so practitioners of these special sciences need not study more fundamental sciences, since these underlying facts are genuinely irrelevant.

The status of fundamental laws is an important issue when deciding between the three broad ontological options of fundamentalism (of which the thesis that physics is complete is typically a sub-type), emergentism, and disorder or promiscuous realism. Cartwright’s assault on fundamental laws which argues that such laws do not, and cannot, typically state the facts, and hence cannot be used to support belief in a fundamental ontological order, is discussed in this context. A case is made in defence of a (...) moderate form of fundamentalism, which leaves open the possibility of emergentism, but sets itself against the view that our best ontology is disordered. The argument, taking its cue from Bhaskar, relies on a consideration of the epistemic status of experiments, and the question of the possible generality of knowledge gained in unusual or controlled environments.

I offer an explicit account of the underdetermination thesis as well as of the many challenges it poses to scientific realism; a way to answer to these challenges is explored and outlined, by shifting attention to the content of theories. I argue that, even if we have solid grounds (as I contend we do) to support that some varieties of the underdetermination thesis are true, scientific realism can still offer an adequate picture of the aims and achievements of science.

Regardless of whatever else physicalism requires, nearly all philosophers agree that physicalism cannot be true in a world which contains fundamental mentality. I challenge this widely held attitude, and describe a world which is plausibly all-physical, yet which may contain fundamental mentality. This is a world in which priority monism is true—which is the view that the whole of the cosmos is fundamental, with dependence relations directed from the whole to the parts—and which contains only a single mental system, like (...) a brain or computer. Because some properties of the whole are fundamental under priority monism, it follows that that the mental properties of a cosmos-encompassing brain or computer system may be fundamental in a priority monist world. Yet such a world need not contain anything physically unacceptable: the mental properties of the cosmos-encompassing brain or computer can be characterized in a physicalism-friendly functionalist or identity-theoretic way. Thus, as I see it, physicalism need not be false in such a world. This constitutes a challenge to those who hold the view that physicalism is inconsistent with the existence of fundamental mentality.

The existence and importance of supervenience principles for identity across times and worlds have been noted, but insufficient attention has been paid to their precise nature. Such attention is repaid with philosophical dividends. The issues in the formulation of the supervenience principles are two. The first involves the relevant variety of supervenience: that variety is global, but there are in fact two versions of global supervenience that must be distinguished. The second involves the subject matter: the names “identity over time” (...) and “identity across worlds” are misnomers, for in neither case is identity at issue. The philosophical dividends then follow. Nathan Salmon’s argument that identity over time needs no “grounds” in matters of qualitative fact can be answered, as can an argument offered by many, that coincident objects would require objectionably ungrounded differences in identities across times and worlds.

Causal necessity typically receives only oblique attention. Causal relations, laws of nature, counterfactual conditionals, or dispositions are usually the immediate subject(s) of interest. All of these, however, have a common feature. In some way, they involve the causal modality, some form of natural or physical necessity. In this paper, causal necessity is discussed with the purpose of determining whether a completely general empiricist theory can account for the causal in terms of the noncausal. Based on an examination of causal relations, (...) laws of nature, counterfactual conditionals, and dispositions, it is argued that no reductive program devoid of essentialist commitments can account for all the phenomena that involve causal necessity. Hence, neo-Humean empiricism fails to provide a framework adequate for understanding causal necessity. (shrink)

In the region where some cat sits, there are many very cat-like items that are proper parts of the cat (or otherwise mereologically overlap the cat) , but which we are inclined to think are not themselves cats, e.g. all of Tibbles minus the tail. The question is, how can something be so cat-like without itself being a cat. Some have tried to answer this “Problem of the Many” (a problem that arises for many different kinds of things we regularly (...) encounter, including desks, persons, rocks, and clouds) by relying on a mereological maximality principle, according to which, something cannot be a member of a kind K if it is a large proper part of, or otherwise greatly mereologically overlaps, a K. It has been shown, however, that a maximality constraint of this type, i.e. one that restricts mereological overlap, is open to strong objections. Inspired by the insights of, especially, Sutton and Madden, I develop a type of functional-maximality principle that avoids these objections (and has other merits), and thereby provides a better answer to the Problem of the Many.

This work gives a new argument for ‘Empirical Philosophy of Mathematical Practice’. It analyses different modalities on how empirical information can influence philosophical endeavours. We evoke the classical dichotomy between “armchair” philosophy and empirical/experimental philosophy, and claim that the latter should in turn be subdivided in three distinct styles: Apostate speculator, Informed analyst, and Freeway explorer. This is a shift of focus from the source of the information towards its use by philosophers. We present several examples from philosophy of mind/science (...) and ethics on one side and a case study from philosophy of mathematics on the other. We argue that empirically informed philosophy of mathematics is different from the rest in a way that encourages a Freeway explorer approach, because intuitions about mathematical objects are often unavailable for non-mathematicians. This consideration is supported by a case study in set theory. (shrink)

Non-reductive physicalists have made a number of attempts to provide the relation of supervenience between levels of properties with enough bite to analyze interesting cases without at the same time losing the relation's acceptability for the physicalist. I criticize some of these proposals and suggest an alternative supplementation of the supervenience relation by imposing a requirement of robustness which is motivated by the notion of structural stability familiar from dynamical systems theory. Robust supervenience, I argue, captures what the non-reductive physicalist (...) wants from supervenience; most importantly, it provides a natural background for reconstructing the notion of (diachronic) property emergence in a way acceptable to physicalists.

The central claim of this paper is that the Aristotelian metaphysics of objects is incompatible with physicalism. This includes the contemporary variant of Aristotelianism I call ‘sortalism’. The core reason is that an object’s identity as an instance of a (natural) kind, as well as its consequent persistence conditions, is neither physically fundamental nor determined by what is physically fundamental. The argument for the latter appeals to what is commonly known as ‘the grounding problem’; in particular I argue that the (...) physicalist has no solution, and this requires that the physicalist jettison the traditional concept of objects having kind-specific identity and persistence conditions.

Do facts about water have a priori, transparent, reductive explanations in terms of microphysics? Ned Block and Robert Stalnaker hold that they do not. David Chalmers and Frank Jackson hold that they do. In this paper I argue that Chalmers.

This article explores the possibility of naturalized theory of action. It distinguishes ontological naturalism from conceptual naturalism, and asks whether a defensible theory of action can be either ontologically or conceptually naturalistic. The distinction between conditions for an ontology and conditions for a concept receives support from Donald Davidson's identification of two modes of explanation for action: rational and physical causal explanation. Davidson's action theory provides a naturalized ontology for action theory, but not a naturalized concept of intentional action. This (...) article raises doubts about Davidson's basis for such one-sided naturalism. It examines some conditions for a mode of explanation, in order to clarify whether an intentional mode of explanation might have ontological significance and thus raise problems for ontological naturalism. The article argues for the central role of certain instrumental factors in explanatory strategies, whether naturalistic or intentional; and it casts doubt on Jaegwon Kim's recent argument that intentional psychology and neuroscience are mutually exclusive as explanatory strategies. A key lesson is that variable end-dependent reasons are our only wherewithal in the evaluation of explanatory strategies. In this sense, our explanatory strategies are ultimately instrumental and perspectival. The article draws out the implications of this lesson for naturalized action theory and for psychological explanation. It opposes any suggested monopoly on explanation from the physical sciences.

Extensive sections cover foundational issues, the nature of consciousness, and the (...) nature of mental content. Three of the selections are published here for the first time, while many other articles have been revised especially for this volume. Each section opens with an introduction by the editor. Philosophy of Mind is suitable for students at all levels and also for general readers. (shrink)

I briefly argue that some issues in the individualism-holism debate have been fairly clearly settled and other issues still plagued by unclarity. The main argument of the paper is that there are a set of clear empirical issues around the holism-individualism debate that are central problems in current social science research. Those include questions about when we can be holist and how individualist we can be in social explanation.

In this paper I pour a little cold water on claims of global supervenience, not by arguing that they are false, and not by arguing that they possess no philosophical utility whatsoever, but by building a case for the following conditional conclusion: if you expect claims of global supervenience to play a certain role in a certain metaphysical project, then you will be disappointed, since they cannot play such a role. The metaphysical project is to give an illuminating and suitably (...) physicalist account of the relations between properties instantiated at different levels of reality. The paper makes a prima facie case for holding that claims of global supervenience can provide no illumination in such an account, a case that emerges when the metaphysics of global supervenience is probed a little more deeply than is customary.

Two ways are considered of formulating a version of retentive physicalism, the view that in some important sense everything is physical, even though there do exist properties, e.g. higher-level scientific ones, which cannot be type-identified with physical properties. The first way makes use of disjunction, but is rejected on the grounds that the results yield claims that are either false or insufficiently materialist. The second way, realisation physicalism, appeals to the correlative notions of a functional property and its realisation, and (...) states, roughly, that any actual property whatsoever is either itself a physical property or else is, ultimately, realised by instances of physical properties. Realisation physicalism is distinctive since it makes no claims of identity whatsoever, and involves no appeal to the dubious concept of supervenience. After an attempt to formulate realisation physicalism more precisely, I explore a way in which, in principle, we could obtain evidence of its truth. (shrink)

Many have felt that it is impossible to defend autonomous laws of social science: where the regularities upheld are law-like it is argued that they are not at base social scientific, and where the phenomena to be explained would seem to require social descriptions, it is argued that laws governing the phenomena are unavailable at that level. But is it possible to develop an ontology that supports the dependence of the social on the physical, while nonetheless supporting the explanatory power (...) of genuinely autonomous social scientific laws? The aim of this paper is to show that reductive explanation is not a requirement of a `naturalist' ontology, thereby defending an account of supervenience as a suitable framework within which to recognize a metaphysical relationship between the natural and the social that is consistent with the pursuit of autonomous nomological social scientific explanations.

Jaegwon Kim and others have claimed that (strong) psychophysical supervenience entails the reducibility of mental properties to physical properties. I argue that this claim is unwarranted with respect to epistemic (explanatory) reducibility (either of a global or of a local sort), as well as with respect to ontological reducibility. I then attempt to show that a robust version of nonreductive materialism (which I call supervenient token-physicalism) can be defended against the charge that nonreductive materialism leads to epiphenomenalism in failing to (...) account for the causal or explanatory relevance of mental properties. (shrink)

The idea of a property's being supervenient on a class of properties is familiar from much philosophical literature. We give this idea a linguistic turn by converting it into the idea of a predicate symbol's being supervenient on a set of predicate symbols relative to a (first order) theory. What this means is that according to the theory, any individuals differing in respect to whether the given predicate applies to them also differ in respect to the application of at least (...) one of the predicates in the set. The latter relationship we show turns out to coincide with something antecedently familiar from work on definability: with what is called the piecewise (or modelwise) definability, in the theory in question, of the given predicate in terms of those in the set. (shrink)

The aim of the paper is to show that claims of supervenience of the mental upon the physical do not define substantial forms of materialism. While weak supervenience holds trivially, even strong supervenience does not justify a claim of identity, dependence or determination; it is only a relation between classifications of persons by psychological and physical properties.

Global supervenience of beliefs about physical states of affairs on such states has strongly counter-intuitive consequences about what beliefs we can nomologically hold. This is an argument against a global supervenience of all mental properties on physical ones, and, since that is implied by strong supervenience, also against that as the preferred materialist thesis.

Theories of cognition and theories of social practices and institutions have often each separately acknowledged the relevance of the other; but seldom have there been consistent and sustained attempts to synthesize these two areas within one explanatory framework. This is precisely what my dissertation aims to remedy. I propose that certain recent developments and themes in philosophy of mind and cognitive science, when understood in the right way, can explain the emergence and dynamics of social practices and institutions. Likewise, the (...) view I construct explains how social practices and institutions shape the character of cognition of their constituent agents. Moreover, I explain both cognitive and social agency under the single explanatory framework provided by Dynamic Systems Theory. Drawing upon the phenomenological tradition, "embodied, "extended", "embedded", "enactive", and "ecological" approaches to cognition, as well as the conceptual resources of Dynamic Systems Theory, I construct a theory of agency that sees cognitive and social agents as far-from-equilibrium, open, recursively self-maintenant dynamic systems. Depending on the specifics of concrete circumstances, such systems, which I call "Dynamic Embodied Agents", may develop and possess emergent capacities for error-detection, flexible learning, normative behavior, representation, self-reflection, various modes of pattern-recognition, a temporal sense of self, and even moral responsibility. Some such systems are also sensitive to perceived social influences ; while reciprocally constituting and causally affecting them. (shrink)

In the first part ("Determination"), I consider different notions of determination, contrast and compare modal with non-modal accounts and then defend two a-modality theses concerning essence and supervenience. I argue, first, that essence is a a-modal notion, i.e. not usefully analysed in terms of metaphysical modality, and then, contra Kit Fine, that essential properties can be exemplified contingently. I argue, second, that supervenience is also an a-modal notion, and that it should be analysed in terms of constitution relations between properties. (...) In the second part ("A Theory of Truthmaking"), I first review the literature on ontological commitment, and argue that the notion of truthmaking is better suited to play its explanatory rôle. I then argue that we should take truthmaker theory seriously, and that we should provide actual truthmakers for all truths there are. In the last chapter of this part, I review Armstrong's truthmaker theories and argue that they are unsatisfactory. I generalise my criticism to an argument against truthmaker necessitarianism, the view that truthmakers necessarily make true the truths they are truthmakers of. In the third part ("Properties and their Kind(s)"), I discuss qualitative determination. I present and endorse the truthmaker argument for universals, and defend universalism against friends of tropes, states of affairs and facts. I then give a novel characterisation of the important class of intrinsic properties, building on Lewis' work. With a workable notion of intrinsicness at hand, I argue that relations are ontologically – but not "ideologically" – dispensable: qualitative determination in general is a matter of intrinsic structure. In the future, I plan to add two parts and to publish my thesis as a book: In the fourth part ("Exemplification"), I argue for the existence of an exemplification relation tying universals and particulars together. I derive theoretical benefits from this relation by providing adverbialist theories of modality and tense and identify exemplification with a type of parthood. In the fifth part ("Qua qua qua"), I investigate the curious and interesting ontological category of so-called "qua-objects" (Picasso-as-a-painter, for example) and argue that they exist, are not identical with transworld indidivuals or modal parts and that they provide (contingent) truthmakers for all true predications.
