Maxwell and materialism

In a recent article, Grover Maxwell presents a case for a kind of mind-brain identity theory which he claims precludes materialism. His case is based on some views about meaning which I find plausible. However, I will argue that, by adopting certain assumptions about the nature of sensory experience, and extending some of Maxwell's views about meaning in a plausible way, the issue of a materialistic identity theory is reopened. Ultimately, I will agree that such a theory is not true, but more is needed to show this than Maxwell gives us. But the question of materialism is not thereby closed, because it has become axiomatic these days that materialism does not require an identity theory. So I will go on to consider if all forms of materialism have been ruled out by Maxwell's theory, as extended by me. I will end with a tentative affirmative answer but also with a proposal which, if it can be worked out, would reverse the decision.     

The location problem in social ontology

Mental, mathematical, and moral facts are difficult to accommodate within an overall worldview due to the peculiar kinds of properties inherent to them. In this paper I argue that a significant class of social entities also presents us with an ontological puzzle that has thus far not been addressed satisfactorily. This puzzle relates to the location of certain social entities. Where, for instance, are organizations located? Where their members are, or where their designated offices are? Organizations depend on their members for their existence, but the members of an organization can be where the organization is not. The designated office of an organization, however, need be little more than a mailbox. I argue that the problem can be solved by conceptualizing the relation between social entities and non-social entities as one of constitution, a relation of unity without identity. Constituted objects have properties that cannot be reduced to properties of the constituting objects. Thus, my attempt to solve the Location Problem results in an argument in favor of a kind of non-reductive materialism about the social.     

Materialism and ‘the soft substance of the brain’: Diderot and plasticity

ABSTRACT

Materialism is the view that everything that is real is material or is the product of material processes. It tends to take either a ‘cosmological’ form, as a claim about the ultimate nature of the world, or a more specific ‘psychological’ form, detailing how mental processes are brain processes. I focus on the second, psychological or cerebral form of materialism. In the mid-to-late eighteenth century, the French materialist philosopher Denis Diderot was one of the first to notice that any self-respecting materialist had to address the question of the status and functional role of the brain, and its relation to our mental life. After this the topic grew stale, with knee-jerk reiterations of ‘psychophysical identity’ in the nineteenth-century, and equally rigid assertions of anti-materialism. In 1960s philosophy of mind, brain–mind materialism reemerged as ‘identity theory’, focusing on the identity between mental processes and cerebral processes. In contrast, Diderot’s cerebral materialism allows for a more culturally sedimented sense of the brain, which he described in his late Elements of Physiology as a ‘book – except it is a book which reads itself’. Diderot thus provides a lesson for materialism as it reflects on the status of the brain, science and culture.     

I, zombie

Certain recent philosophical theories offer the prospect that zombies are possible. These theories argue that experiential contents, or qualia, are nonphysical properties. The arguments are based on the conceivability of alternate worlds in which physical laws and properties remain the same, but in which qualia either differ or are absent altogether. This article maintains that qualia are, on the contrary, physical properties in the world. It is shown how, under the burden of the a posteriori identification of qualia with physical properties, a reasoned choice can be made between the two types of theories which ultimately favors materialism and rejects zombies.     

Subsumption and Relative Identity

This paper is a modification of Nicola Guarino and Christopher Welty's conception of the subsumption relation. Guarino and Welty require that that whether one property may subsume the other should depend on the modal metaproperties of those properties. I argue that the part of their account that concerns the metaproperty carrying a criterion of identity is essentially flawed. Subsequently, I propose to constrain the subsumption relation not, as Guarino and Welty require, by means of incompatible criteria of absolute identity but by means of incompatible criteria of relative identity. After discussing the benefits of applying relative identity in ontological investigations I provide a formal framework in which to prove a counterpart of the identity criteria constraint.This revised version was published online in October 2005 with corrections to the Cover Date.     

Rigidity and actuality-dependence

It is generally assumed that rigidity plays a key role in explaining the necessary a posteriori status of identity statements, both between proper names and between natural kind terms. However, while the notion of rigid designation is well defined for singular terms, there is no generally accepted definition of what it is for a general term to be rigid. In this paper I argue that the most common view, according to which rigid general terms are the ones which designate the same kind in all possible worlds, fails to deliver a posteriori necessities. I also present an alternative view, on which the work of explaining a posteriori necessities is not done by rigidity, but by a related metasemantic notion, which I call actuality-dependence.     

Necessary a Posteriori Identity Truths: Fregeanism Beats Direct Reference Theory

I argue that Fregeanism with respect to proper names—the view that modes of presentation are relevant to the contents of proper names—is able to account for the thesis that there are necessarily true a posteriori identity propositions such as the one expressed in “Hesperus is identical with Phosphorus”, whereas the Direct Reference Theory—according to which the semantic function of certain expressions, e.g., proper names, is only to pick out an object (referent)—is able to deal with only their necessary truth. Thus, at least in so far as necessarily true a posteriori identity propositions are concerned, Fregeanism should be preferred to the Direct Reference Theory.     

Cross-count identity,distinctness, and the theory of internal and external relations

Baxter (Australas J Philos 79:449–464, 2001) proposes an ingenious solution to the problem of instantiation based on his theory of cross-count identity. His idea is that where a particular instantiates a universal it shares an aspect with that universal. Both the particular and the universal are numerically identical with the shared aspect in different counts. Although Baxter does not say exactly what a count is, it appears that he takes ways of counting as mysterious primitives against which different numerical identities are defined. In contrast, I defend the idea—suggested, though not quite endorsed, by Baxter himself—that counts are independent dimensions of numerical identity. Different ways of counting are explained by the existence of these different sorts of identity (i.e., counts). For the instantiation of a universal by a particular, I propose one dimension concerned with the individuation of particulars (the p-count) and another dimension concerned with the individuation of universals (the u-count). On that basis, I give a clear definition of cross-count identity that explains its asymmetrical nature (i.e., the fact that particulars instantiate universals, but not vice versa). I extend the theory to a third dimension—that of time, or the t-count—and thereby defend Baxter’s ideas on change, and the contingency of instantiation. Baxter (Mind 97(388):575–582, 1988; Australas J Philos 79:449–464, 2001) proposes the related idea of composition as (cross-count) identity. Parts are individually cross-count identical with the wholes that they constitute, and they collectively share all aspects across counts with those wholes. I propose an innovation by which totality is shared distinctness across counts. The theory applies to both the totality of particulars that instantiate any given universal, and the totality of parts that constitute any given whole. I argue that this has several advantages over Armstrong’s view, which is based on a dubious external totalling relation. I also argue that Armstrong’s theory of numbers (or quantities) as internal relations ought to be rejected in favour of an account based on identity and distinctness. The paper concludes with a careful analysis of external relations in Baxter’s framework. I argue that we must recognise one further dimension of identity in order to differentiate between, e.g., the aspects of Abelard insofar as he loves Heloise and Abelard insofar as he loves Isobel. Each of these aspects is identical with Abelard and identical with loving-by, yet they must be in some way distinct. I therefore propose the r-count, in which multiple distinct relational properties are the very same relation (-part). The existence of these four independent dimensions explains the fact that particulars, universals, relations, and times are fundamentally different sorts of things in the ontology. Each is individuated with respect to a different dimension of identity.     

How Superduper Does a Physicalist Supervenience Need to Be?

The standard formulations of the supervenience relation present the supervenience of one set of properties on another in terms of property correlations, without placing any constraints on the dependency relation concerned. This does not ensure that properties supervening upon phys-icalistically acceptable base properties are not themselves emergent in a way at odds with materialism. So physicalism needs 'superdupervenience'. I argue that, where supervenient and base properties are instantiated in the same individuals, Horgan's requirement of robust explanation is neither sufficient nor necessary for superdupervenience. His paradigm case is compatible with the supervenient property's being emergent. This and other unacceptable possibilities may be ruled out by means of a metaphysical constraint on the supervenience relation, which must be internal. Each individual causal power in the set associated with a given supervenient property must be numerically identical with a causal power in the set associated with its base property. Satisfying this condition is all that is needed to render supervenience superduper. In fact a wide variety of non-reductive physicalist accounts are implicitly or explicitly designed to meet this condition, and so are more similar than they seem.     

The Cogito and the Metaphysics of Mind

Descartes used the cogito to make two points the epistemological point that introspection affords us absolute certainty of our existence, and the metaphysical point that subjects are thinking things logically distinct from bodies. Most philosophers accept Descartes’s epistemological claim but reject his metaphysical claim. I argue that we cannot do this if the cogito works, then subjects are non-physical. Although I refrain from endorsing an argument for dualism based on this conditional, I discuss how such an argument would differ from the conceivability arguments pursued by Descartes in the Sixth Meditation and by contemporary philosophers. Unlike those arguments, this argument would not be refuted by the discovery of a posteriori identities between physical and phenomenological properties. In other words, it is possible to argue for substance dualism even if phenomenal properties are physical properties.     

The twofold role of diagrams in Euclid’s plane geometry

Proposition I.1 is, by far, the most popular example used to justify the thesis that many of Euclid??s geometric arguments are diagram-based. Many scholars have recently articulated this thesis in different ways and argued for it. My purpose is to reformulate it in a quite general way, by describing what I take to be the twofold role that diagrams play in Euclid??s plane geometry (EPG). Euclid??s arguments are object-dependent. They are about geometric objects. Hence, they cannot be diagram-based unless diagrams are supposed to have an appropriate relation with these objects. I take this relation to be a quite peculiar sort of representation. Its peculiarity depends on the two following claims that I shall argue for: (i) The identity conditions of EPG objects are provided by the identity conditions of the diagrams that represent them; (ii) EPG objects inherit some properties and relations from these diagrams.     

Ontological Security and Public (Mis)Recognition of International Crises: Uncertainty,Political Imagining,and the Self

Public narratives of unexpected international events frequently help (re)imagine uncertainty as something familiar or predictable. This process underlies social and political responses and is deeply significant in relation to identity and boundary security. I propose to read early perceptions of international crises through a reformulation of ontological security principles that find motivation for behavior in self‐identity needs. Political imagining is shown to seek continuous self‐concepts and to routinize new encounters within familiar and self‐affirming frames. This article suggests a new approach to ontological continuity: instead of an unchanging narrative, its security may rest in a continuously positive version of the self, with narratives of others balancing and securing the relationship. In the second half of the article, I draw on interviews about the “Arab Spring” to show how illusions of recognizing unexpected events and the political imagining this produces can be motivated by self‐concepts in need of security.     

Christian materialism in a scientific age

Many Christians who argue against Christian materialism direct their arguments against what I call ‘Type-I materialism’, the thesis that I cannot exist without my organic body. I distinguish Type-I materialism from Type-II materialism, which entails only that I cannot exist without some body that supports certain mental functions. I set out a version of Type-II materialism, and argue for its superiority to Type-I materialism in an age of science. Moreover, I show that Type-II materialism can accommodate Christian doctrines like the Resurrection of the Body, the Incarnation, and the “intermediate state” (if there is one).     

物质主义都是有害的吗?——来自实证和概念的挑战

物质主义指的是一种强调拥有物质财富对于个人生活重要性的价值观念。过往研究多强调其消极效应,但此观点日益面临挑战。实证研究表明物质主义在某些条件下能提升幸福感,也可以作为不安全感的补偿策略。在概念层面,有研究者基于动机的视角指出工具性物质主义是无害的,并且物质主义作为一种身份目标追求,能够建构和维持自我身份。未来研究需进一步为动机取向的物质主义概念提供实证研究的支持、评估物质主义补偿不安全感和提升幸福感的效果、基于认知和动机的整合视角考察物质主义对幸福感的积极影响。     

The Problem of Verisimilitude and Counting Partially Identical Properties

In this paper I propose a solution to the qualitative version of David Miller's verisimilitude reversal argument. Miller (1974) shows that verisimilitude rankings are relative to language choice and hence, are not objective. My solution stems from a reply to an earlier solution proposed by Eric Barnes (1991). Barnes argues that the verisimilitude reversal problem can be solved by revealing an epistemic dimension. I show that Miller's problem cannot be solved by side-stepping foundational metaphysical claims as his epistemic solution suggests. Rather, a substantive metaphysical basis grounds identity relations among properties. The problem of verisimilitude cannot be solved without embracing the fundamental metaphysical distinctions between basic and composite properties that ground the relationship of partial identity among properties.     

Schelling on understanding organisms

In this paper, I attempt to reconstruct Schelling’s theory of organism, primarily as it is elaborated in the First Outline of a System of the Philosophy of Nature and the Introduction to the Outline. First, I discuss the challenge that the properties of organisms presented to the dominant scientific viewpoint by the end of the eighteenth century. I present different responses to this challenge, including reductive materialism, metaphysical and heuristic vitalism, and the Kantian response, and I situate Schelling’s account of organism with respect to these responses. I argue that while Schelling agrees with vitalism in that he wants to preserve the specificity of organic phenomena, he rejects principles such as vital forces or the formative drive postulated by vitalism, even for purely heuristic purposes. I argue that Schelling understands organisms fundamentally in terms of the coordinated functioning of their organs. I further clarify Schelling’s account of problematic organic phenomena by focusing on his treatment of the relation between organic activity and organic receptivity. For Schelling, organic activity and organic receptivity mutually condition each other. I provide a detailed account of how this is supposed to work.     

Indiscernible Persons

In this article I discuss identity and indiscernibility for person-stages and persons. Identity through time is not an identity relation (it is a unity relation). Identity is carefully distinguished from persistence. Identity is timeless and necessary. Person-stages are carefully distinguished from persons. Theories of personal persistence are not theories of identity for persons. I deal not with the persistence of persons through time but with the timeless and necessary identity and indiscernibility of persons. I argue that it is possible that there are non-identical but indiscernible temporally whole persons. I discuss the biographies of persons and develop the type or token distinction for persons. Twins in symmetrical or eternally recurrent universes are examples of indiscernible persons. I discuss temporal and modal branching, and I end with survival for person-tokens and eternity for person-types.     

Moving from Feminist Identity Politics To Coalition Politics Through a Feminist Materialist Standpoint of Intersubjectivity in Gloria Anzaldúa's Borderlands/La Frontera: The New Mestiza

Identity politics deployed by lesbian feminists of color challenges the philosophy of the subject and white feminisms based on sisterhood, and in so doing opens a space where feminist coalition building is possible. I articulate connections between Gloria Anzaldúa's epistemological-political action tools of complex identity narration and mestiza form of intersubject, Nancy Hartsock's feminist materialist standpoint, and Seyla Benhabib's standpoint of intersubjectivity in relation to using feminist identity politics for feminist coalition politics.     

Hard Luck: How Luck Undermines Free Will and Moral Responsibility

I reconcile the spatiotemporal location of repeatable artworks and impure sets with the non-location of natural numbers despite all three being varieties of abstract objects. This is possible because, while the identity conditions for all three can be given by abstraction principles, in the former two cases spatiotemporal location is a congruence for the equivalence relation featuring in the relevant principle, whereas in the latter it is not. I then generalize this to other ‘physical’ properties like shape, mass, and causal powers.     

Enthusiasm Versus Self-Possession: The Art of Psychological Science

In this article, I propose that psychology is an art, and that it can be so without forfeiting its identity as a developing science. In support of this proposal, I outline the ways in which art and science unnecessarily have become dichotomized, and I suggest a framework for integrating art and science. This integration is based on reframing the art versus science tension as a vehicle through which the basic human dynamic of "enthusiasm versus self-possession" is expressed. I apply this new framework to the field of psychology and outline ways in which research and practice in psychology can be unified to produce an integrated, dynamic, and creative field.
