Fred Dretske’s account of mental causation, developed in Explaining Behavior and defended in numerous articles, is generally regarded as one of the most interesting and most ambitious approaches in the field. According to Dretske, meaning facts, construed historically as facts about the indicator functions of internal states, are the structuring causes of behavior. In this article, we argue that Dretske’s view is untenable: On closer examination, the real structuring causes of behavior turn out to be markedly different from Dretske’s meaning (...) facts. Our argument proceeds in three steps. First, we set forth the problem of meaning individuation: We argue that the proposal that meaning facts are structuring causes of behavior commits Dretske to a very fine-grained individuation of meanings that is deeply counterintuitive. In a second step, we show that even these finely individuated meaning facts cannot do the job that they are supposed to do, since information facts—which are constitutive of, but distinct from Dretske’s meaning facts—are better candidates for the role of structuring causes. Finally, we argue that it is not even information facts, but facts of co-instantiation which are the real structuring causes of behavior. In concluding, we briefly consider the options that are left for Dretske if our arguments succeed. (shrink)

Can a group be morally responsible instead of, or in addition to, its members? An influential defense of corporate responsibility is based on results in social choice theory suggesting that a group can form and act on attitudes held by few, or even none, of its members. The members therefore cannot be (fully) responsible for the group’s behavior; the group itself, as a corporate agent, must be responsible. In this paper, I reject this view of corporate responsibility by showing how (...) it pays insufficient attention to individual agency. By accounting for group members’ strategic behavior, we shall see how they control collective attitude formation and are therefore responsible for their group’s behavior. (shrink)

The recognition of striking regularities in the physical world plays a major role in the justification of hypotheses and the development of new theories both in the natural sciences and in philosophy. However, while scientists consider only strictly natural hypotheses as explanations for such regularities, philosophers also explore meta-natural hypotheses. One example is mathematical realism, which proposes the existence of abstract mathematical entities as an explanation for the applicability of mathematics in the sciences. Another example is theism, which offers the (...) existence of a supernatural being as an explanation for the design-like appearance of the physical cosmos. Although all meta-natural hypotheses defy empirical testing, there is a strong intuition that some of them are more warranted than others. The goal of this paper is to sharpen this intuition into a clear criterion for the admissibility of meta-natural explanations for empirical facts. Drawing on recent debates about the indispensability of mathematics and teleological arguments for the existence of God, I argue that a meta-natural explanation is admissible just in case the explanation refers to an entity that, though not itself causally efficacious, guarantees the instantiation of a causally efficacious entity that is an actual cause of the regularity.

In this article we aim to see how far one can get in defending the identity thesis without challenging the inference from conceivability to possibility. Our defence consists of a dilemma for the modal argument. Either “pain” is rigid or it is not. If it is not rigid, then a key premise of the modal argument can be rejected. If it is rigid, the most plausible semantic account treats “pain” as a natural-kind term that refers to its causal or historical (...) origin, namely, C-fibre stimulation. It follows that any phenomenon that is not C-fibre stimulation is not pain, even if it is qualitatively similar to pain. This means there could be phenomena that feel like pain but are not pain since they are not C-fibre stimulation. These possible phenomena can be used to explain away the apparent conceivability of pain without C-fibre stimulation. On either horn of the dilemma, the identity theorist has ample resources to respond to Kripke's argument, even without wandering into the contentious territory of conceivability and possibility.

Semantic normativism, which is the view that semantic properties/concepts are some kind of normative properties/concepts, has become increasingly influential in contemporary meta-semantics. In this paper, I aim to argue that semantic normativism has difficulty accommodating the causal efficacy of semantic properties. In specific, I raise an exclusion problem for semantic normativism, inspired by the exclusion problem in the philosophy of mind. Moreover, I attempt to show that the exclusion problem for semantic normativism is peculiarly troublesome: while we can solve mental-physical (...) exclusion by adopting the so-called ‘autonomy approach’, a similar autonomy solution to semantic exclusion is implausible if semantic properties are understood as normative properties. (shrink)

Recently some philosophers suggested an exclusion problem for moral non-naturalism, which is similar to the exclusion problem in philosophy of mind. In this article, the author aims to advance the discussion of exclusion in morality by investigating two influential solutions to the exclusion problem: the autonomy solution and the overdetermination solution. The author attempts to show that the moral non-naturalist can solve the exclusion problem in a way that is different from the approach to solving mental-physical exclusion. First, the author (...) argues that while the autonomy solution to mental exclusion may work, a similar autonomy approach to moral exclusion is implausible. Second, the author argues that whereas the overdetermination solution to mental exclusion fails, a similar overdetermination solution to moral exclusion is promising. (shrink)

Many philosophers insist that the most plausible solution to the exclusion problem is to adopt the so-called ‘autonomy approach’, which denies either upward or downward causation between mental and physical properties. But the question of whether the autonomy approach is compatible with respectable theories of causation has seldom been discussed in the literature. This paper considers two influential theories of causation, the counterfactual account and the regularity account. I argue that neither the counterfactual theory nor the regularity theory can support (...) the autonomy approach – while the counterfactual approach fails to block downward causation, the regularity approach is unable to refute upward causation. (shrink)

It is generally believed that moral reductionism is immune from notorious problems in moral metaphysics and epistemology, such as the problem of moral explanation – it is at least on this dimension that moral reductionism scores better than moral anti- reductionism. However, in this article I reject this popular view. First, I argue that moral reductionism fails to help vindicate the explanatory efficacy of moral properties because the reductionist solution is either circular or otiose. Second, I attempt to show that (...) a successful vindication, if any, of moral explanation requires moral-descriptive irreducibility. My discussion thus raises an explanatory challenge to moral reductionism. (shrink)

The purpose of this paper is to address a well-known dilemma for physicalism. If mental properties are type identical to physical properties, then their causal efficacy is secure, but at the cost of ruling out mentality in creatures very different to ourselves. On the other hand, if mental properties are multiply realizable, then all kinds of creatures can instantiate them, but then they seem to be causally redundant. The causal exclusion problem depends on the widely held principle that realized properties (...) inherit their causal powers from their realizers. While this principle holds for functional realization, it fails on a broader notion of realization that permits the realization of complex qualitative properties such as spatial and temporal patterns. Such properties are best seen as dependent powerful qualities, which have their causal roles in virtue of being the qualities they are, and do not inherit powers from their realizers. Recent studies have identified one such property—neural synchrony—as a correlate of consciousness. If synchrony is also partially constitutive of consciousness, then phenomenal properties are both multiply realizable and causally novel. I outline a version of representationalism about consciousness on which this constitution claim holds. (shrink)

Are the special sciences autonomous from physics? Those who say they are need to explain how dependent special science properties could feature in irreducible causal explanations, but that’s no easy task. The demands of a broadly physicalist worldview require that such properties are not only dependent on the physical, but also physically realized. Realized properties are derivative, so it’s natural to suppose that they have derivative causal powers. Correspondingly, philosophical orthodoxy has it that if we want special science properties to (...) bestow genuinely new causal powers, we must reject physical realization and embrace a form of emergentism, in which such properties arise from the physical by mysterious brute determination. In this paper, I argue that contrary to this orthodoxy, there are physically realized properties that bestow new causal powers in relation to their realizers. The key to my proposal is to reject causal-functional accounts of realization and embrace a broader account that allows for the realization of shapes and patterns. Unlike functional properties, such properties are defined by qualitative, non-causal specifications, so realizing them does not consist in bestowing causal powers. This, I argue, allows for causal novelty of the strongest kind. I argue that the molecular geometry of H2O—a qualitative, multiply realizable property—plays an irreducible role in explaining its dipole moment, and thereby bestows novel powers. On my proposal, special science properties can have the kind of causal novelty traditionally associated with strong emergence, without any of the mystery. (shrink)

In The Metaphysics of Truth, Doug Edwards offers a sustained case against deflationism about truth and in favour of his preferred pluralist theory of truth. Here, I take up three of the main components of that case. The first is Edwards' account of the distinctive metaphysical commitments of deflationism. His views about this issue have changed over the past few years, and I detail these changes as well as a concern for the views that he develops in the book. Second, (...) I take up the argument that Edwards offers for thinking that deflationism is, in a certain sense, internally unstable. I explain why this argument is inconclusive, outlining three responses to it on behalf of the deflationist. Third, I consider Edwards' novel argument for truth pluralism, which acts as an indirect argument against deflationism. After sorting out some interpretive nuances related to the use of definite descriptions in this argument, I show how the deflationist can resist it. Having responded to Edwards' critique of deflationism, I close by briefly explaining why I take the methodology of deflationism to be especially promising, insofar as it underscores the significance of empirically-informed inquiry about truth.

Individualists claim that wide explanations in psychology are problematic. I argue that wide psychological explanations sometimes have greater explanatory power than individualistic explanations. The aspects of explanatory power I focus on are causal depth and theoretical appropriateness. Reflection on the depth and appropriateness of other wide explanations of behavior, such as evolutionary explanations, clarifies why wide psychological explanations sometimes have more causal depth and theoretical appropriateness than narrow psychological explanations. I also argue for the rejection of eliminative materialism.

This paper examines Jaegwon Kim's Supervenience Argument (SA) against nonreductive physicalism, concentrating on Kim's response to two of the most important objections against the SA: First, the Overdetermination Argument, according to which Kim has no convincing argument against the possibility that mental causation might be a case of genuine or systematic overdetermination; second, the Generalization Argument, according to which the SA would entail that causation at any level gives way to causation at the next lower level, thereby leading to an (...) untenable all-encompassing epiphenomenalism. It is argued that as of yet, Kim has failed to develop a coherent overall position, since various moves he makes in response to these criticisms are strangely at odds with other parts of his philosophical position.

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, despite their irreducibility, their ability to make a causal difference to the course of the causally closed physical world. For a long time however, the nature of realization has largely been ignored in the philosophy of mind until a couple of years ago authors like Carl Gillett, Derk (...) Pereboom, or Sydney Shoemaker proposed accounts 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 nonreductive 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: it is important for the non-reductive physicalist to understand what exactly the realization relation amounts to, but it does not solve the problem of mental causation. (shrink)

Epistemological approaches to mental causation argue that the notorious problem of mental causation as captured in the question “How can irreducible, physically realized, and potentially relational mental properties be causally efficacious in the production of physical effects?” has a very simple solution: One merely has to abandon any metaphysical considerations in favor of epistemological considerations and accept that our explanatory practice is a much better guide to causal relevance than the metaphysical reasoning carried out from the philosophical armchair. I argue (...) that epistemological approaches to mental causation do not enjoy any genuine advantage over theories which treat the problem of mental causation as a genuinely metaphysical problem.

Frank Jackson and Philip Pettit have defended a non-reductive account of causal relevance known as the ‘program explanation account’. Allegedly, irreducible mental properties can be causally relevant in virtue of figuring in non-redundant program explanations which convey information not conveyed by explanations in terms of the physical properties that actually do the ‘causal work’. I argue that none of the possible ways to spell out the intuitively plausible idea of a program explanation serves its purpose, viz., defends non-reductive physicalism against (...)

Over the past fifteen years there has been a considerable amount of debate concerning what theoretical population dynamic models tell us about the nature of natural selection and drift. On the causal interpretation, these models describe the causes of population change. On the statistical interpretation, the models of population dynamics models specify statistical parameters that explain, predict, and quantify changes in population structure, without identifying the causes of those changes. Selection and drift are part of a statistical description of population (...) change; they are not discrete, apportionable causes. Our objective here is to provide a definitive statement of the statistical position, so as to allay some confusions in the current literature. We outline four commitments that are central to statisticalism. They are: 1. Natural Selection is a higher order effect; 2. Trait fitness is primitive; 3. Modern Synthesis (MS)-models are substrate neutral; 4. MS-selection and drift are model-relative. (shrink)

Mental causation, our mind's ability to causally affect the course of the world, is part and parcel of our ‘manifest image’ of the world. That there is mental causation is denied by virtually no one.

Taking 'rationalized judgments' to be those formed by inference from other judgments, I argue against 'Extreme Determinism': the thesis that theoretical rationalization just is a kind of predetermination of 'conclusion-judgments' by 'premise-judgments'. The argument rests upon two key lemmas: firstly, that a deliberator - in this case, his/her assent to some proposition - to be predetermined (I call this the 'Openness Requirement'): secondly, that a subject's logical insight into his/her premise-judgments must enter into the explanation of any judgment s/he forms (...) that is rationalized by those judgments. My contention is that, given the Openness Requirement, no version of Extreme Determinsim can allow for the role played by logical insight in the rationalization of judgment. I end by indicating briefly how this result might figure in a wider argument against any form of determinism about rationalized judgment, and by explaining why I have focused specifically upon rebutting a deterministic view of theoretical as opposed to 'practical' rationalization.

[This paper is available as open access from the publisher.] Normative theories aim to explain why things have the normative features they have. This paper argues that, contrary to some plausible existing views, one important kind of normative explanations which first-order normative theories aim to formulate and defend can fail to transmit downward along chains of metaphysical determination of normative facts by non-normative facts. Normative explanation is plausibly subject to a kind of a justification condition whose satisfaction may fail to (...) transmit along the relevant kind of metaphysical hierarchy. A broader aim of the paper is to contribute to systematic theorizing about normative explanation: whereas there has been a great deal of work on scientific explanation, there has been little by way of systematic exploration of what sort of explanations normative theories aim to formulate and defend.

Apparently, aiming to comply with the norm ‘Believe that P if and only if the proposition that P is true’ can hardly differ from aiming to comply with the norm ‘Believe that P if and only if the proposition that P is epistemically justified’. So one may be tempted to agree with Richard Rorty that the distinction between truth and justification is pragmatically useless because it cannot make any difference ‘when the question is about what I should believe now’. I (...) resist this conclusion by arguing that the distinction between truth and justification is pragmatically useful even if the two properties are indeed normatively coincident. The argument I offer turns on the claim that truth plays an explanatory role that justification is inherently incapable of playing. However, my contention is not just that the distinction between truth and justification is pragmatically useful because truth is a bona fide explanatory notion. It is that the distinction between truth and justification is pragmatically useful because the realization that the former plays an explanatory role that the latter is inherently incapable of playing gives access to reasons which would otherwise escape our attention. If truth is a bona fide explanatory notion, the distinction between truth and justification is pragmatically useful because it is precisely when the question is about what I should believe now that attending to such a distinction will often make a difference – and it will make a difference even if the two properties are in fact normatively coincident.

The problem this paper deals with is the problem of how dispositional properties can have causal relevance. In particular, the paper is focused on the question of how dispositions can have causal relevance given that the categorial bases that realise them seem to be sufficient to bring about the effects that dispositions explain. I show first that this problem of exclusion has no general solution. Then, I discuss some particular cases in which dispositions are causally relevant, despite of this exclusion (...) problem. My claim is that dispositions have causal relevance in selection or recruitment processes, when they are converted into teleological functions. (shrink)

Recent years have seen renewed interest in the emergence issue. The contemporary debate, in contrast with that of past times, has to do not so much with the mind–body problem as with the relationship between the physical and other domains; mostly with the biological domain. One of the main sources of this renewed interest is the study of complex and, in general, far-from-equilibrium self-preserving systems, which seem to fulfil one of the necessary conditions for an entity to be emergent; namely, (...) that its causal powers are not predictable from the causal powers of basic physical properties. However, I argue that much of the current emergentism debate has misfired by focusing on the interpretation of self-maintaining systems. In contrast, I claim that if we want to find emergent properties, we should look not at complex systems, but at selection (natural selection, in particular). I argue that selection processes make the causal world ‘exuberant’ by making non-physical functional and relational properties enter the causal web of the world. (shrink)

According to a model defended by some authors, dispositional concepts can be legitimately used in causal explanations, although such a use is not necessary. I argue, however, that there is a kind of use of dispositions in explanations that does not fall within this model: we will miss some explanations if we forsake dispositional concepts and explanations.

In a recent paper, Bird (in: Groff (ed.) Revitalizing causality: Realism about causality in philosophy and social science, 2007 ) has argued that some higher-order properties—which he calls “evolved emergent properties”—can be considered causally efficacious in spite of exclusion arguments. I have previously argued in favour of a similar position. The basic argument is that selection processes do not take physical categorical properties into account. Rather, selection mechanisms are only tuned to what such properties can do, i.e., to their causal (...) powers. This picture seems ultimately untenable in the light of further exclusion problems; but at the same time, it meets our explanatory demands. My purpose is therefore to show that there is a real antinomy with regard to evolved emergent properties. I develop a physicalist exclusion argument and then I go on to consider an argument that seems to establish that evolved emergent properties are causally efficacious, and propose a compatibilist solution. Finally, I very briefly consider what the proposed model may imply for the issue of mental causation. (shrink)

In this paper, I want to explore the question of whether or not there are laws in psychology. Jaegwon Kim has argued (Supervenience and mind. MIT press, Cambridge; 1993; Mind in a physical world. MIT press, Cambridge 1998) that there are no laws in psychology that contain reference to multiply realized kinds, because statements about such kinds fail to be projectible. After reviewing Kim’s argument for this claim, I show how his conclusion hinges on a hidden assumption: that a kind (...) can only feature in a projectible statement if it is defined by an internal physical property. This assumption, however, is false: constrained kinds can feature in projectible statements, and yet they are not defined by any set of internal physical properties. I suggest that many mental terms actually refer to constrained kinds, and give an example from motor neuroscience of a constrained kind that is multiply realizable and “projectible”: the intention to move voluntarily in a specific direction.

Many philosophers believe that judgments about propositional attitudes, or about which mental states are expressed by which sentences, are normative judgments. If this is so, then metanormative expressivism must be given expressivist treatment. This might seem to make expressivism self-defeating or worrisomely circular, or to frustrate the explanatory ambitions central to the view. I argue that recent objections along these lines to giving an expressivist account of expressivism are not successful. I shall also suggest that in order to deal with (...) these worries, Dreier's influential response to the so-called ‘problem of creeping minimalism’ must be slightly revised. (shrink)

Social sciences face a well-known problem, which is an instance of a general problem faced as well by psychological and biological sciences: the problem of establishing their legitimate existence alongside physics. This, as will become clear, is a problem in metaphysics. I will show how a new account of structural explanations, put forward by Frank Jackson and Philip Pettit, which is designed to solve this metaphysical problem with social sciences in mind, fails to treat the problem in any importantly new (...) way. Then I will propose a more modest approach, and show how it does not deserve the criticism directed at a prototype by Jackson and Pettit. (shrink)

This chapter offers an introduction to naturalist views in contemporary metaethics. Such views attempt to find a place for normative properties (such as goodness and rightness) in the concrete physical world as it is understood by both science and common sense. The chapter begins by introducing simple naturalist conceptual analyses of normative terms. It then explains how these analyses were rejected in the beginning of the 20th Century due to G.E. Moore’s influential Open Question Argument. After this, the chapter considers (...) what good general reasons there are for defending naturalism in metaethics. The bulk of the chapter will then survey new semantic and metaphysical forms of naturalism which in different ways attempt to address Moore’s objection to naturalism. These more recent versions of naturalism—using new resources from philosophy of language, philosophy of mind, metaphysics, philosophy of science and epistemology—attempt to explain why the Open Question Argument fails.

Nonnaturalist realism is the view that normative properties are unique kind of stance-independent properties. It has been argued that such views fail to explain why two actions that are exactly alike otherwise must also have the same normative properties. Mark Schroeder and Knut Olav Skarsaune have recently suggested that nonnaturalist realists can respond to this supervenience challenge by taking the primary bearers of normative properties to be action kinds. This paper develops their response in two ways. First, it provides additional (...) motivation for the previous claim about the bearers of normative properties by drawing from the work of H. A. Prichard. Second, and more importantly, it formulates a plausible metaphysical framework based on the contemporary trope theory to explain why action kinds would have their second-order properties, including their normative properties, necessarily.

Many philosophers take mental causation to be required for free will. But it has also been argued that the most popular view of the nature of mental states, i.e. non-reductive physicalism, excludes the existence of mental causation, due to what is known as the ‘exclusion argument’. In this paper, I discuss the difference-making account of mental causation proposed by [List, C., and Menzies, P. 2017. “My Brain Made Me Do It: The Exclusion Argument Against Free Will, and What’s Wrong with (...) It.” In H. Beebee, C. Hitchcock, & H. Price (eds.), Making a Difference: Essays on the Philosophy of Causation. Oxford Scholarship Online: Oxford University Press], who argue that their account not only solves the problem of causal exclusion but also saves free will. More precisely, they argue that it rebuts what they call ‘the Neurosceptical Argument’, the argument that if actions are caused by neural states and processes unavailable to us, there is no free will. I argue that their argument fails for two independent reasons. The first reason is that they fail to show that difference-makers are independent causes. The second reason is that physical realizers of mental states can be individuated in a way that makes both mental states and their realizers difference-makers. (shrink)

I aim to reconcile two apparently conflicting theses: (a) Everything that can be explained, can be explained in purely physical terms, that is, using the machinery of fundamental physics, and (b) some properties that play an explanatory role in the higher level sciences are irreducible in the strong sense that they are physically undefinable: their nature cannot be described using the vocabulary of physics. I investigate the contribution that physically undefinable properties typically make to explanations in the high-level sciences, and (...) I show that when they are explanatorily relevant, it is in virtue of their extension (or something close) alone. They are irreducible because physics cannot capture their nature; this is no obstacle, however, to physics' more or less capturing their extension, which is all that it need do to duplicate their explanatory power. In the course of the argument, I sketch the outlines of an account of the explanation of physically contingent regularities, such as the regularities found in most branches of biological inquiry, at the center of which is an account of the nature of contingent, empirical bridge principles.

Understanding how individual agency and group agency relate is of great importance for a range of philosophical and practical concerns, including responsibility ascription and institutional design. This article discusses the relation between corporate and individual responsibility in agency—in particular, the relation between corporate and individual control of actions. First, I criticize Christian List and Philip Pettit’s causal account of combined corporate and individual control. Second, I develop an alternative account in terms of structural control, and I show how this gives (...) a better grasp of the issue. Third, I argue for an act-dualism that complements my account of control and sheds further light on the relation between corporate and individual agency and responsibility. (shrink)

Recently, many philosophers have claimed that the world has an ordered, hierarchical structure, where entities at lower ontological levels are said to metaphysically ground entities at higher ontological levels. Other philosophers have recently claimed that our language has an ordered, hierarchical structure. Semantically primitive sentences are said to conceptually ground less primitive sentences. It’s often emphasized that metaphysical grounding is a relation between things out in the world, not a relation between our sentences. But conflating these relations is easy to (...) do, given that both types of grounding are expressed by non-causal “in-virtue-of” claims. The purpose of this paper is to clarify the relation between metaphysical and conceptual grounding. I argue that conceptual and metaphysical grounding are exclusive: if a given in-virtue-of claim involves conceptual grounding, then it does not involve metaphysical grounding. I also develop some heuristics for deciding which type of grounding is relevant in a given case. These heuristics suggest that many proposed cases of metaphysical grounding do not actually involve metaphysical grounding at all. (shrink)

In this paper, I clarify the relation between two types of grounding: metaphysical and conceptual. Metaphysical grounding relates entities at more and less fundamental ontological levels. Conceptual grounding relates semantically primitive sentences and semantically derivative sentences. It is important to distinguish these relations given that both types of grounding can underwrite non-causal “in-virtue-of” claims. In this paper, I argue that conceptual and metaphysical grounding are exclusive: if a given in-virtue-of claim involves conceptual grounding, then it does not involve metaphysical grounding. (...) I then present two heuristics for deciding which type of grounding is relevant to a given case. These heuristics suggest that certain proposed cases of metaphysical grounding may not actually involve metaphysical grounding at all. (shrink)

In the first section of this paper I argue that the main reason why Daniel Dennett’s Intentional Systems Theory (IST) has been perceived as behaviourist or antirealist is its inability to account for the causal efficacy of the mental. The rest of the paper is devoted to the claim that by emending the theory with a phenomenon called ‘empathic resonance’ (ER), it can account for the various explananda in the mental causation debate. Thus, IST + ER is a much more (...) viable option than IST, even though IST + ER assigns a crucial role to the phenomenology of agency, a role that is incompatible with Dennett’s writings on consciousness.

This article examines the use of mathematical concepts in philosophy, focusing on topology, which may be viewed as a modern supplement to geometry. We show that Plato and Parmenides were already employing geometric ideas in their research, and discuss three examples of the application of topology to philosophical problems: the first concerns the analysis of the Cartesian distinction between res extensa and res cogitans, the second the ontology of possible worlds of Wittgenstein's Tractatus, and the third Leibniz's monadology. We also (...) consider the role of topology in mathematical explanations of the sort found in science, arguing that it can perform a role in philosophy that is of comparable importance. (shrink)

In this paper I argue that the explanationist argument in favour of moral realism fails. According to this argument, the ability of putative moral properties to feature in good explanations provides strong evidence for, or entails, the metaphysical claims of moral realism.

I argue that even if we accept that moral explanations are (sometimes) good explanations the metaphysical claims of realism do not (...) follow. (shrink)

Sydney Shoemaker has recently given an account of emergent properties according to which emergent properties are a special type of structural property and the determination relation holding between emergent properties and their base properties is one of "mere nomological supervenience." According to Shoemaker, emergent properties are what he calls type-2 microstructural properties, whereas physical properties are type-1 microstructural properties. After highlighting the advantages of viewing emergent properties as a special class of microstructural properties, I show how according to his own (...) causal theory of properties type-2 microstructural properties actually reduce to type-1 microstructural properties, and thus do not truly count as emergent. I then suggest an alternative view according to which emergent properties are actually a third type of microstructural property, one not considered by Shoemaker. I conclude with reflections why we might view the dependence relation between emergent properties and their physical base properties as a causal relation rather than one of mere supervenience.

The Generalized Integration Challenge is the task of providing, for a given domain of discourse, a simultaneously acceptable metaphysics, epistemology and metasemantics and showing them to be so. In this paper, we focus on a metaethical position for which seems particularly acute: the brand of normative realism which takes normative properties to be mind-independent and causally inert. The problem is that these metaphysical commitments seem to make normative knowledge impossible. We suggest that bringing metasemantics into play can help to resolve (...) this puzzle. We propose an independently plausible metasemantic constraint on reference determination and show how it can provide a plausible response to for this brand of normative realism. (shrink)

Since the late 1980’s Kim has presented some major reasons to abandon SC. In MIAPW at least four of these reasons are offered: under SC we lose mental causation, mental realism and psychological explanations. Moreover, supervenience cannot do the job as the cementing relation in SC.

Aidan Lyon has recently argued that some mathematical explanations of empirical facts can be understood as program explanations. I present three objections to his argument.

We demonstrate how real progress can be made in the debate surrounding the enhanced indispensability argument. Drawing on a counterfactual theory of explanation, well-motivated independently of the debate, we provide a novel analysis of ‘explanatory generality’ and how mathematics is involved in its procurement. On our analysis, mathematics’ sole explanatory contribution to the procurement of explanatory generality is to make counterfactual information about physical dependencies easier to grasp and reason with for creatures like us. This gives precise content to key (...) intuitions traded in the debate, regarding mathematics’ procurement of explanatory generality, and adjudicates unambiguously in favour of the nominalist, at least as far as explanatory generality is concerned.
