This thesis investigates the causal theory of properties (CTP). CTP states that properties must be understood via the complicated network of causal relations to which a property can contribute. If an object instantiates the property of being 900C, for instance, it will burn human skin on contact, feel warm to us if near, etc. In order to best understand CTP, I argue that we need to distinguish between properties and particular instances of them. (...) class='Hi'>Properties should be analysed via the causal relations their instances stand in, it is this oven’s being 900C which causes my skin to burn, etc. The resulting CTP offers an illuminating analysis of properties. First, it provides a criterion of identity for properties, their identity being analysed via the causal roles property instances realise. It also offers an account of how property instances are sorted into genuine kinds, in cases of determinables and determinates. I show how we can distinguish between genuine and non-genuine similarity via the property instances of objects. The implications of CTP for an analysis of causation are then investigated. I argue that the proposed CTP offers a plausible causal ontology. The fine-grainedness of property instances enables us to capture the subtleties involved in questions concerning what causes what. But, even more importantly, CTP enables us to reconcile two highly attractive theses concerning the causal relation. The first of these is the generalist’s thesis. This states that causal relations are part of more general patterns. The second of these is the singularist’s thesis. This states that the causal connection between two entities, doesn’t depend upon anything extraneous to that relation. I argue that by combining CTP with an ontology of tropes, we can thereby respect what is driving both singularism and generalism.Logic & Metaphysics. (shrink)

Sydney Shoemaker’s causal theory of properties is an important starting place for some contemporary metaphysical perspectives concerning the nature of properties. In this paper, I discuss the causal and intrinsic criteria that Shoemaker stipulates for the identity of genuine properties and relations, and address George Molnar’s criticism that holding both criteria presents an unbridgeable hypothesis in the causal theory of properties. The causal criterion requires that properties and relations contribute (...) to the causal powers of objects if they are to be deemed genuine rather than ‘mere-Cambridge’. The intrinsic criterion requires that all genuine properties and relations be intrinsic. Molnar’s S-property argument says that these criteria conflict if one considers extrinsic spatiotemporal properties and relations to contribute causally. In this paper, I argue that a solution to the contradiction that Molnar identifies involves a denial of discreteness between objects, leading to a power holist perspective and a resulting deflationary account of intrinsicality.

Causal structuralism is the view that, for each natural, non-mathematical, non-Cambridge property, there is a causal profile that exhausts its individual essence. On this view, having a property’s causal profile is both necessary and sufficient for being that property. It is generally contrasted with the Humean or quidditistic view of properties, which states that having a property’s causal profile is neither necessary nor sufficient for being that property, and with the double-aspect view, which states that (...) causal profile is necessary but not sufficient. Shoemaker’s (1998) and Hawthorne’s (2001) arguments in favor of causal structuralism primarily focus on problematic consequences of the other two views. I argue, however, that causation does not provide an appropriate framework within which to characterize all physical properties for two main reasons. First, there are physical properties that do not have causal profiles and properties whose causal profiles do not exhaust their essences. Second, there is no unified notion of causation across the sciences. After distinguishing between the causal and the nomological, I suggest that what is needed is a structuralist view of properties that is not merely causal but that incorporates a physical property’s higher-order mathematical and nomological properties into its identity conditions. Such a view retains the naturalistic motivations for causal structuralism while avoiding the problems it faces. (shrink)

This dissertation argues that we have no good reason to accept any one theory of properties as correct. To show this, I present three possible bases for theory-choice in the properties debate: coherence, explanatory adequacy, and explanatory value. Then I argue that none of these bases resolve the underdetermination of our choice between theories of properties. First, I argue considerations about coherence cannot resolve the underdetermination, because no traditional theory of properties is obviously (...) incoherent. Second, I argue considerations of explanatory adequacy cannot resolve the underdetermination, because every traditional theory of properties lacks the theoretical resources to adequately explain resemblance, causal powers, and predication. However, these inadequacies are easily remedied with theoretical modifications. But this results in an overabundance of modified, but adequate, theories of properties. Third, I argue explanatory virtues cannot resolve the underdetermination, because we have no reason to think explanatory virtues make theories of properties more likely to be true. I reject the common argument that explanatory virtues are truth-conducive in theories of properties because they are truth-conducive in scientific theories. Since none of the three bases for theory choice can resolve the underdetermination, I conclude that we have no good reason to accept any one theory of properties as correct. Finally, I consider the possibility of choosing one theory over the others on pragmatic grounds. But I argue that pragmatic grounds cannot resolve the underdetermination either. Instead, I suggest we accept the view I call 'instrumental pluralism,' which allows practitioners to use whatever theory of properties they find useful. Adviser: Jennifer McKitrick. (shrink)

ABSTRACT Proponents of the causal theory of perception have applied the theory to questions about which particular objects or events are perceived, which parts are perceived, and which properties are perceived. In each case, they insist that successful perception is causally dependent on what is perceived. The causal theory rests on an important insight regarding the information-carrying role of perception. In order to succeed in this role, perception cannot be grounded in spurious correlations. But (...) we can respect this insight without embracing the idea that a successful percept must be causally dependent on what is perceived. A correlation in nature can also be genuine or lawful when it arises from a common cause. I show how successful perception is frequently achieved through correlation via a common cause. (shrink)

This paper uses an example from biology, the homology concept, to argue that current versions of the causal theory of reference give an incomplete account of reference determination. It is suggested that in addition to samples and stereotypical properties, the scientific use of concepts and the epistemic interests pursued with concepts are important factors in determining the reference of natural kind terms.

According to the Causal Theory of Memory, remembering a particular past event requires a causal connection between that event and its subsequent representation in memory, specifically, a connection sustained by a memory trace. The CTM is the default view of memory in contemporary philosophy, but debates persist over what the involved memory traces must be like. Martin and Deutscher argued that the CTM required memory traces to be structural analogues of past events. Bernecker and Michaelian, contemporary CTM (...) proponents, reject structural analogues in favor of memory traces as distributed patterns of event features. The proposals are understood as distinct accounts of how memory traces represent past events. But there are two distinct questions one could ask about a trace’s representational features. One might ask how memory traces, qua mental representations, have their semantic properties. Or, what makes memory traces, qua mental representations of memories, distinct from other mental representations. Proponents of the CTM, both past and present, have failed to keep these two questions distinct. The result is a serious but unnoticed problem for the CTM in its current form. Distributed memory traces are incompatible with the CTM. Such traces do not provide a way to track the causal history of individual memories, as the CTM requires. If memory traces are distributed patterns of event features, as Bernecker and Michaelian each claim, then the CTM cannot be right. (shrink)

The project of explaining intentional phenomena in terms of nonintentional phenomena has become a central task in the philosophy of mind.' Since intentional phenomena like believing, desiring, intending have content essentially, the project is one of showing how semantic properties like content can be reconciled with nonsemantic properties like cause. As Jerry A. Fodor put it, The worry about representation is above all that the semantic (and/or the intentional) will prove permanently recalcitrant to integration in the natural order; (...) for example that the semantic/intentional properties of things will fail to supervene upon their physical properties.2.

The causal theory of perception has come under a great deal of critical scrutiny from philosophers of mind interested in the nature of perception. M. H. Newman's set-theoretic objection to Russell's structuralist version of the CTP, in his 1928 paper “Mr Russell's Causal Theory of Perception” has not, to my knowledge, figured in these discussions. In this paper I aim to show that it should: Newman's objection can be generalized to yield a particularly powerful and incisive (...) challenge to all versions of the CTP. In effect it says that if the CTP is true, at least one of the following claims must be false. Our perception-based judgements are made true or false by the state of mind independent objects. The concepts we use in such judgments refer to the intrinsic, mind-independent properties of such objects. Experience provides us with knowledge of these properties. The paper sets out the structure of the problem as Newman saw it, extends it to current debates in theory of perception and considers various responses to it. The response I argue for involves jettisoning the CTP in favour of a relational account of perceptual experience, in a way that allows us to hold onto all three claims. (shrink)

The causal theory of reference is often taken to provide a solution to the problems, such as incomparability and referential discontinuity, that the meaning-change thesis raised. I show that Kuhn successfully questioned the causal theory and Putnam's idea that reference is determined via the sameness relation of essences that holds between a sample and other members of a kind in all possible worlds. Putnam's single ‘essential' properties may be necessary but not sufficient to determine membership (...) in a kind category. Kuhn argued that extension is fixed by similarity-dissimilarity relations that are liable to change in taxonomic reorganizations of science. *Received October 2009; revised January 2010. †To contact the author, please write to: Institute of Philosophy, University of Leiden, Martin de Vrieshof 4, 2300 RS Leiden, The Netherlands; e-mail: [email protected].

This is a paper about The Causal Self-Referential Theory of Perception. According to The Causal Self-Referential Theory as developed by above all John Searle and David Woodruff Smith, perceptual content is satisfied by an object only if the object in question has caused the perceptual experience. I argue initially that Searle's account cannot explain the distinction between hallucination and illusion since it requires that the state of affairs that is presented in the perceptual experience must exist (...) in order for the perception to be veridical. Smith's account is interestingly different in that the descriptive content, i.e. the content that presents the perceptual object as having certain properties, does not determine the object of the experience. His account consequently does not require that the state of affairs that is presented in perception exists in order for the perception to have an object. Smith argues instead that perceptual reference is determined by a specific kind of demonstrative content. In this paper it is argued that Smith's account of demonstrative content is too indeterminate and in certain circumstances prescribes the wrong object. It is subsequently argued that the theory of demonstrative content can be modified so as to avoid these consequences. This modification involves deriving the conditions of satisfaction of seeing an object from the conditions of satisfaction of seeing the shape of the object, where the shape of the object is conceived of as a particularized property, what is also called a ‘trope’.

A recent version of the causal theory of time makes crucial use of a concept of the genidentity of events when it attempts to define temporal betweenness in terms of empirical, physical properties. By presenting and discussing an apparent counter-example it is argued that the role of genidentity in an empirical theory of time is problematic. In particular, it may be that the temporal behavior of objects is used to decide which events are genidentical, and, if (...) so, the definition of temporal betweenness is circular. On the other hand, though there are strategies for avoiding the charge of circularity, in certain hypothetical situations the definition may yield inconsistent temporal orders. Then, the definition would have to be supplemented by a choice of temporal orders, and this choice may introduce an element of conventionality into the causal theory of time. (shrink)

Two arguments Paul Snowdon has brought against the causal theory of perception are examined. One involves the claim that, based on the phenomenology of perceptual situations, it cannot be the case that perception is an essentially causal concept. The other is a reductio , according to which causal theorists’ arguments imply that a proposition Snowdon takes to be obviously non-causal ( A is married to B ) can be analyzed into some sort of indefinite ‘spousal (...) connection’ plus a causal ingredient . I conclude that neither argument is sound. The reason that Snowdon’s critiques fail is that, since causal theories need not be about ‘effect ends’ that are internally manifest to perceivers, no such ostensibly separable, non-causal property as it being to S as if he were perceiving O need be an essential element in a causal theory of perception.

This paper seeks a new perspective on a long-standing ambiguity in historical materialism. The term "property," its apparent inclusion in both the economic base and the politicolegal superstructure in Marx's schema, and the consequent difficulty of asserting a causal connection between base and superstructure, are seen as deriving from intellectual influences on the young Marx. These influences conveyed certain central ideas from the history of Roman law and its treatment of property. Some implications for Marxist theory are considered.

The verbs cause, enable, and prevent express beliefs about the way the world works. We offer a theory of their meaning in terms of the structure of those beliefs expressed using qualitative properties of causal models, a graphical framework for representing causal structure. We propose that these verbs refer to a causal model relevant to a discourse and that “A causes B” expresses the belief that the causal model includes a link from A to (...) B. “A enables/allows B” entails that the model includes a link from A to B, that A represents a category of events necessary for B, and that an alternative cause of B exists. “A prevents B” entails that the model includes a link from A to B and that A reduces the likelihood of B. This theory is able to account for the results of four experiments as well as a variety of existing data on human reasoning. (shrink)

According to the causal-historical theory of reference, natural kind terms refer in virtue of complicated causal relations the speakers have to their environment. A common objection to the theory is that purely causal relations are insufficient to fix reference in a determinate fashion. The so-called hybrid view holds that what is also needed for successful fixing are true descriptions associated in the mind of the speaker with the referent. The main claim of this paper is (...) that the objection fails: reference fixing of natural kind terms can be purely causal. The main argument draws inspiration from recent theoretical advances made in metaphysics of kinds by Marion Godman, Antonella Mallozzi, and David Papineau. The main claim is that their notion of super-explanatory properties may explain how reference of many kind terms can be fixed purely causally. (shrink)

Correspondence theories are frequently charged with being either implausible—metaphysically troubling and overly general—or trivial—collapsing into deflationism's “‘P’ is true iff P.” Philip Kitcher argues for a “modest” correspondence theory, on which reference relations are causal relations, but there is no general theory of denotation. In this article, I start by showing that, understood this way, “modest” theories are open to charges of triviality. I then offer a refinement of modesty, and take the first steps toward articulating a (...) modest correspondence theory, giving a particular account of the relation between predicates, properties, and extensions. Finally, I argue that my account does not collapse into a deflationary one. (shrink)

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

The dispositional properties encountered in everyday experience seem to have causal bases in other properties, e.g., the microstructure of a vase is the causal basis of its fragility. In contrast, the Pure Dispositions Thesis maintains that some dispositions require no causal basis. This thesis faces the Problem of Being: without a causal basis, there appears to be no grounds for the existence of pure dispositions. This paper establishes criteria for evaluating the problem, critically examines (...) four theories of the being of pure dispositions, and develops an explanation of how a pure disposition grounds itself via its own power.

If mental causal explanations are grounded in facts about physical causes and effects, and if there are no psychophysical laws, how can we avoid the conclusion that the mental is causally, and causally explanatorily, irrelevant? The chapter analyses the ways in which this objection has been raised against non‐reductive monism in general, and Davidson's anomalous monism in particular. Then a conception of explanatory relevance for non‐basic physical properties is set out: properties are candidates for explanatory relevance if (...) they play a role in a simple model of causal action; it is intelligible how a property can be causally explanatorily relevant only if it supervenes on low‐level physical properties; but such supervenience does not provide a self‐standing condition of explanatory relevance. A parallel model is developed for the mental case, exploiting the intuitive model of rational action and appealing to supervenience. Anomalous monism is thereby defended against one objection; but, it is argued, this defence challenges the original motivation for thinking that mental events must be physical events. (shrink)

Appraisal theories of emotion generally presuppose that emotions are “directed at” various items. They also hold that emotions have motivational properties. However, although it coheres well with their views, they have yet to seriously develop the idea that the function of emotional direction is to guide those properties. I argue that this “guidance hypothesis” can open up a promising new field of research in emotion theory. But I also argue that before appraisal theorists can take full advantage (...) of it, they must drop their further assumption that to determine an emotion's direction, one need only retrace the process that caused it. Contrary to this “retracing view,” I argue for an “independence thesis”: directed emotions are produced by two functionally independent sub-processes. The first, “affect-causation,” functions in part to produce a state with certain motivational properties given certain representations. The second, “affect-direction,” has the function of optimally guiding those motivational properties by associating them with representations that may properly be quite dissimilar from the causal ones. By provisionally adopting the independence thesis and empirically testing the guidance hypothesis, I argue that appraisal theorists stand a good chance of significantly increasing the explanatory power of their theories.

Leibniz's mature philosophy is monadological. The only true substances are monads which Leibniz compares to Cartesian res cogitans. In the monadological view, the only variant properties of monads are perceptions of varying degrees of distinctness; corporeal substances are phenomena that supervene on the ordered perceptions of monads. Monads continually change their perceptions, and in this minimal sense, monads are constantly active. The question that any account of Leibniz's monadological view must answer is: What causes the change in the perceptions (...) of monads? To answer this question is to gain clarity not only about Leibniz's monadological account of change, but also about Leibniz's views on causality and explanation for phenomena, since it is the changes in perceptions of monads that seem to account for changes in phenomena.

Necessitarianism, as we shall use the term, is the view that natural properties and causal powers are necessarily connected in some way. In recent decades the most popular forms of necessitarianism have been the anti-Humean powers-based theories of properties, such as dispositional essentialism and the identity theory. These versions of necessitarianism have come under fire in recent years and I believe it is time for necessitarians to develop a new approach. In this paper I identify unexplored (...) ways of positing metaphysically necessary connections in nature, using the concepts of grounding and essential dependence. For example, I show that one could be a necessitarian by insisting that the properties of things necessarily ground their powers, and that one can maintain this while rejecting dispositional essentialism. Using different combinations of claims about grounding and essential dependence, I map out a spectrum of new positions and compare them to previous theories of natural modality. Some of these positions are compatible with Humean metaphysics while others are not. The overall aim of the paper is to provide a new metaphysical framework for understanding theories of powers and thereby launch a new necessitarian research programme. (shrink)

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

Does mere passage of time have causal powers ? Are properties like "being n days past" causally efficient ? A pervasive intuition among metaphysicians seems to be that they don't. Events and/or objects change, and they cause or are caused by other events and/or objects; but one does not see how just the mere passage of time could cause any difference in the world. In this paper, I shall discuss a case where it seems that mere passage of (...) time does have causal powers : Sydney Shoemaker's (1969) possible world where temporal vacua (allegedly) take place. I shall argue that Shoemaker's thought-experiment doesn't really aim at teaching us that there can be time without change, but rather that if such a scenario is plausible at all (as I think it is) it provides us with good reasons to think that mere passage of time can be directly causally efficient.

The language of nonmonotonic causal theories, defined by Norman McCain and Hudson Turner, is an important formalism for representing properties of actions. For causal theories of a special kind, called definite, a simple translation into the language of logic programs under the answer set semantics is available. In this paper we define a similar translation for causal theories of a more general form, called al-.

Qualia are the elements of phenomenal consciousness -- the raw feels which constitute what it is like to be in a conscious mental state. Some claim that qualia are epiphenomenal properties -- mere by-products of brain function which are causally inert. Though this is an implausible theory, it is difficult to show that it is false. Here I present an ad hominem argument -- the argument from coincidence -- which shows that epiphenomenalism about qualia is explanatorily deficient because (...) it leaves unexplained a highly improbable state of affairs, and so we have good reason to suppose that qualitative properties must be causally efficacious, and must be so in virtue of their qualitative nature.

One primary goal for metaphysical theories of natural kinds is to account for their epistemic fruitfulness. According to cluster theories of natural kinds, this epistemic fruitfulness is grounded in the regular and stable co- occurrence of a broad set of properties. In this paper, I defend the view that such a cluster theory is insufficient to adequately account for the epistemic fruitfulness of kinds. I argue that cluster theories can indeed account for the projectibility of natural kinds, but (...) not for several other epistemic operations that natural kinds support. Natural kinds also play a role in scientific explanations and categorizations. A theory of natural kinds can only account for these additional kind-based epistemic practices if it also analyzes their causal structure. (shrink)

Laws of nature are merely expressions of the powers possessed by various kinds of things, and counterfactual conditionals are grounded in the powers and tendencies of the entities involved in the counterfactual supposition together with their counterfactual surroundings. There are two versions of Strong Powerism. One takes the truthmakers for causal laws to be universals (a 'Realist' version). The second takes the truthmakers for causal laws to be the particulars that fall under the laws (a 'Nominalist' version). This (...) chapter focuses on how Powerism compares to other views about the laws. Neo‐Humeism has the leanest metaphysical theory, since its class of fundamental truths includes no conditionals, laws of nature or attributions of power. Metaphysically, Nomism is burdened with a large number of brute necessities, linking laws with actual patterns of particular fact. The chapter talks about the causal theory of properties: causal structuralism. (shrink)

Formalizing commonsense knowledge for reasoning about time has long been a central issue in AI. It has been recognized that the existing formalisms do not provide satisfactory solutions to some fundamental problems, viz. the frame problem. Moreover, it has turned out that the inferences drawn do not always coincide with those one had intended when one wrote the axioms. These issues call for a well-defined formalism and useful computational utilities for reasoning about time and change. Yoav Shoham of Stanford University (...) introduced in his 1986 Yale doctoral thesis an appealing temporal nonmonotonic logic and identified a class of theories, causal theories, which have computationally simple model-theoretic properties. This paper is a study towards building upon Shoham's work on causal theories. We concentrate on improving computational aspects of causal theories while preserving their model-theoretic properties.

This book addresses central issues in the philosophy and metaphysics of science, namely the nature of scientific theories, their partial truth, and the necessity of scientific laws within a moderate realist and empiricist perspective. Accordingly, good arguments in favour of the existence of unobservable entities postulated by our best theories, such as electrons, must be inductively grounded on perceptual experience and not their explanatory power as most defenders of scientific realism claim. Similarly, belief in the reality of dispositions such as (...) causal powers which ground the natural necessity of scientific laws must be based on experience. Hence, this book offers a synthetic presentation of an original metaphysics of science, namely a metaphysics of properties, both categorical and dispositional, while at the same time opposing strong versions of necessitarism according to which laws are true in all possible worlds. The main theses and arguments are clearly presented in a non-technical way. Thus, on top of being of interest to the specialists of the topics discussed, it is also useful as a textbook in courses for third year and more advanced university students. (shrink)

Two of the most important concepts in contemporary philosophy of mind are computation and consciousness. This paper explores whether there is a strong relationship between these concepts in the following sense: is a computational theory of consciousness possible? That is, is the right kind of computation sufficient for the instantiation of consciousness. In this paper, I argue that the abstract nature of computational processes precludes computations from instantiating the concrete properties constitutive of consciousness. If this is correct, then (...) not only is there no viable computational theory of consciousness, the Human Mental State Multiple Realizability in Silicon Thesis is almost certainly false. (shrink)

This paper shows that several live philosophical and scientific hypotheses – including the holographic principle and multiverse theory in quantum physics, and eternalism and mind-body dualism in philosophy – jointly imply an audacious new theory of free will. This new theory, "Libertarian Compatibilism", holds that the physical world is an eternally existing array of two-dimensional information – a vast number of possible pasts, presents, and futures – and the mind a nonphysical entity or set of properties (...) that "read" that physical information off to subjective conscious awareness (in much the same way that a song written on an ordinary compact-disc is only played when read by an outside medium, i.e. a CD-player). According to this theory, every possible physical “timeline” in the multiverse may be fully physically deterministic or physically-causally closed but each person’s consciousness still entirely free to choose, ex nihilo, outside of the physical order, which physically-closed timeline is experienced by conscious observers. Although Libertarian Compatibilism is admittedly fantastic, I show that it not only follows from several live scientific and philosophical hypotheses, I also show that it (A) is a far more explanatorily powerful model of quantum mechanics than more traditional interpretations (e.g. the Copenhagen, Everett, and Bohmian interpretations), (B) makes determinate, testable empirical predictions in quantum theory, and finally, (C) predicts and explains the very existence of a number of philosophical debates and positions in the philosophy of mind, time, personal identity, and free will. First, I show that whereas traditional interpretations of quantum mechanics are all philosophically problematic and roughly as ontologically “extravagant” as Libertarian Compatibilism – in that they all posit “unseen” processes – Libertarian Compatibilism is nearly identical in structure to the only working simulation that human beings have ever constructed capable of reproducing (and so explaining) every general feature of quantum mechanics we perceive: namely, massive-multiplayer-online-roleplaying videogames (or MMORPGs). Although I am not the first to suggest that our world is akin to a computer simulation, I show that existing MMORPGs (online simulations we have already created) actually reproduce every general feature of quantum mechanics within their simulated-world reference-frames. Second, I show that existing MMORPGs also replicate (and so explain) many philosophical problems we face in the philosophy of mind, time, personal identity, and free will – all while conforming to the Libertarian Compatibilist model of reality. -/- I conclude, as such, that as fantastic and metaphysically extravagant as Libertarian Compatibilism may initially seem, it may well be true. It explains a number of features of our reality that no other physical or metaphysical theory does. (shrink)

In this paper, I present a general theory of topological explanations, and illustrate its fruitfulness by showing how it accounts for explanatory asymmetry. My argument is developed in three steps. In the first step, I show what it is for some topological property A to explain some physical or dynamical property B. Based on that, I derive three key criteria of successful topological explanations: a criterion concerning the facticity of topological explanations, i.e. what makes it true of a particular (...) system; a criterion for describing counterfactual dependencies in two explanatory modes, i.e. the vertical and the horizontal; and, finally, a third perspectival one that tells us when to use the vertical and when to use the horizontal mode. In the second step, I show how this general theory of topological explanations accounts for explanatory asymmetry in both the vertical and horizontal explanatory modes. Finally, in the third step, I argue that this theory is universally applicable across biological sciences, which helps to unify essential concepts of biological networks. (shrink)

It is widely agreed that properties play causal roles: they capture the causal powers of things. But do properties have their causal roles essentially? David Lewis did not think so. He adhered to the doctrine of quidditism, namely the doctrine that the identity of properties is primitive and that they can trade their causal roles. Quidditism is controversial. But Lewis did not see why he should want to reject it. He knew that he (...) could avoid quidditism on the cheap by treating individuals and properties alike in rejecting transworld multilocation of properties and endorsing a counterpart theory for properties. But he did not see why he should want to do so. In this article, I argue that Lewis should have wanted to endorse a counterpart theory for properties in order to reject quidditism. My argument concerns resemblance relations among properties. Another constitutive role of properties is that they capture objective resemblances between their instances. The premises of my argument are intuitive claims about resemblances among some properties that Lewis held on Humean grounds. (shrink)

It has long been recognized that a local hidden variable theory of quantum mechanics can in principle be constructed, provided one is willing to countenance pre-measurement correlations between the properties of measured systems and measuring devices. However, this ‘conspiratorial’ approach is typically dismissed out of hand. In this article I examine the justification for dismissing conspiracy theories of quantum mechanics. I consider the existing arguments against such theories, and find them to be less than conclusive. I suggest a (...) more powerful argument against the leading strategy for constructing a conspiracy theory. Finally, I outline two alternative strategies for constructing conspiracy theories, both of which are immune to these arguments, but require one to either modify or reject the common cause principle.

The relationship of mind and matter is approached in a new way in this article. This approach is based on the causal interpretation of the quantum theory, in which an electron, for example, is regarded as an inseparable union of a particle and afield. This field has, however, some new properties that can be seen to be the main sources of the differences between the quantum theory and the classical (Newtonian) theory. These new properties (...) suggest that the field may be regarded as containing objective and active information, and that the activity of this information is similar in certain key ways to the activity of information in our ordinary subjective experience. The analogy between mind and matter is thus fairly close. This analogy leads to the proposal of the general outlines of a new theory of mind, matter, and their relationship, in which the basic notion is participation rather than interaction. Although the theory can be developed mathematically in more detail, the main emphasis here is to show qualitatively how it provides a way of thinking that does not divide mind from matter, and thus leads to a more coherent understanding of such questions than is possible in the common dualistic and reductionistic approaches. These ideas may be relevant to connectionist theories and might perhaps suggest new directions for their development. (shrink)

Causal theories of mental content attempt to explain how thoughts can be about things. They attempt to explain how one can think about, for example, dogs. These theories begin with the idea that there are mental representations and that thoughts are meaningful in virtue of a causal connection between a mental representation and some part of the world that is represented. In other words, the point of departure for these theories is that thoughts of dogs are about dogs (...) because dogs cause the mental representations of dogs. (shrink)

Theories of modality which invoke possible worlds have recently been challenged by accounts that appeal to dispositional properties. A prominent strand of the accounts maintains that there is an intimate link between dispositions and possibility. The link is said to be captured by the proposition that, at first approximation, a state of affairs is possible just in case there is some actual disposition whose manifestation is the state. Focusing on the most detailed exposition and defence of this approach, put (...) forward by Barbara Vetter, I critically examine the adequacy of the view of dispositional properties on which it rests and which seems to be required by any plausible dispositionalist account of possibility. In the course of doing so, I offer arguments in favour of the causal nature of dispositions. (shrink)

The relationship of mind and matter is approached in a new way in this article. This approach is based on the causal interpretation of the quantum theory, in which an electron, for example, is regarded as an inseparable union of a particle and afield. This field has, however, some new properties that can be seen to be the main sources of the differences between the quantum theory and the classical (Newtonian) theory. These new properties (...) suggest that the field may be regarded as containing objective and active information, and that the activity of this information is similar in certain key ways to the activity of information in our ordinary subjective experience. The analogy between mind and matter is thus fairly close. This analogy leads to the proposal of the general outlines of a new theory of mind, matter, and their relationship, in which the basic notion is participation rather than interaction.
