    The completeness of physics
    Dissertation, University of Natal, Durban. 1999.
    The present work is focussed on the completeness of physics, or what is here called the Completeness Thesis: the claim that the domain of the physical is causally closed. Two major questions are tackled: How best is the Completeness Thesis to be formulated? What can be said in defence of the Completeness Thesis? My principal conclusions are that the Completeness Thesis can be coherently formulated, and that the evidence in favour if it significantly outweighs that against it. In opposition to th…Read more

    Notions of Cause: Russell’s Thesis Revisited
    with Don Ross
    British Journal for the Philosophy of Science 58 (1): 45-76. 2007.
    We discuss Russell's 1913 essay arguing for the irrelevance of the idea of causation to science and its elimination from metaphysics as a precursor to contemporary philosophical naturalism. We show how Russell's application raises issues now receiving much attention in debates about the adequacy of such naturalism, in particular, problems related to the relationship between folk and scientific conceptual influences on metaphysics, and to the unification of a scientifically inspired worldview. In…Read more

    Hostile Scaffolding
    with Ryan Timms
    Philosophical Papers 52 (1): 1-30. 2023.
    Most accounts of cognitive scaffolding focus on ways that external structure can support or augment an agent’s cognitive capacities. We call cases where the interests of the user are served benign scaffolding and argue for the possibility and reality of hostile scaffolding. This is scaffolding which depends on the same capacities of an agent to make cognitive use of external structure as in benign cases, but that undermines or exploits the user while serving the interests of another agent. We de…Read more

    Evolving resolve
    Behavioral and Brain Sciences 44. 2021.
    The broad spectrum revolution brought greater dependence on skill and knowledge, and more demanding, often social, choices. We adopt Sterelny's account of how cooperative foraging paid the costs associated with longer dependency, and transformed the problem of skill learning. Scaffolded learning can facilitate cognitive control including suppression, whereas scaffolded exchange and trade, including inter-temporal exchange, can help develop resolve.

    What Physical Properties Are
    Pacific Philosophical Quarterly 82 (2): 201-225. 2001.
    This paper concerns the question of how to specify what is to count as physical for the purposes of debates concerning either physicalism or the completeness of physics. I argue that what is needed from an account of the physical depends primarily on the particular issue at stake, and that the demand for a general a priori specification of the physical is misplaced. A number of attempts to say what should be counted as physical are defended from recent attacks by Chris Daly, and a specific proposa…Read more

    Cartwright on laws and composition
    International Studies in the Philosophy of Science 15 (3). 2000.
    Cartwright attempts to argue from an analysis of the composition of forces, and more generally the composition of laws, to the conclusion that laws must be regarded as false. A response to Cartwright is developed which contends that properly understood composition poses no threat to the truth of laws, even though agreeing with Cartwright that laws do not satisfy the "facticity" requirement. My analysis draws especially on the work of Creary, Bhaskar, Mill, and points towards a general rejection …Read more

    A recurring claim in a number of behavioural, cognitive and neuro-scientific literatures is that there is, or must be, a unidimensional ‘common currency’ in which the values of different available options are represented. There is striking variety in the quantities or properties that have been proposed as determinants of the ordering in motivational strength. Among those seriously suggested are pain and pleasure, biological fitness, reward and reinforcement, and utility among economists, who hav…Read more

    Affordances are standardly understood as perceived possibilities for interaction. What is afforded is in turn regarded as dependent on the properties of a body and its environment. Human bodies are nearly ubiquitously clothed, and clothing can change the capabilities of bodies. We argue that when clothing does this, it should be regarded as an affordance transforming technology. Clothing receives passing attention in remarks by Gibson, and some empirical work in ecological psychology uses worn i…Read more

    [A slightly revised version of this paper has been accepted by the BJPS] More attention has been devoted to providing evolutionary scenarios accounting for the development of beliefs, or belief-like states, than for desires or preferences. Here I articulate and defend an evolutionary rationale for the development of psychologically real preference states. Preferences token or represent the expected values of discriminated states, available actions, or action-state pairings. The argument is an ap…Read more

    How to do things without words
    with S. J. Cowley
    Language Sciences 26 (5): 443-466. 2004.
    Clark and Chalmers (1998) defend the hypothesis of an ‘Extended Mind’, maintaining that beliefs and other paradigmatic mental states can be implemented outside the central nervous system or body. Aspects of the problem of ‘language acquisition’ are considered in the light of the extended mind hypothesis. Rather than ‘language’ as typically understood, the object of study is something called ‘utterance-activity’, a term of art intended to refer to the full range of kinetic and prosodic features o…Read more

    Does intragenomic conflict predict intrapersonal conflict?
    Biology and Philosophy 31 (3): 313-333. 2016.
    Parts of the genome of a single individual can have conflicting interests, depending on which parent they were inherited from. One mechanism by which these conflicts are expressed in some taxa, including mammals, is genomic imprinting, which modulates the level of expression of some genes depending on their parent of origin. Imprinted gene expression is known to affect body size, brain size, and the relative development of various tissues in mammals. A high fraction of imprinted gene expression …Read more

    A wave of recent work in metaphysics seeks to undermine the anti-reductionist, functionalist consensus of the past few decades in cognitive science and philosophy of mind. That consensus apparently legitimated a focus on what systems do, without necessarily and always requiring attention to the details of how systems are constituted. The new metaphysical challenge contends that many states and processes referred to by functionalist cognitive scientists are epiphenomenal. It further contends that…Read more

    Affording Affordances
    Teorema: International Journal of Philosophy. forthcoming.
    A striking feature of the latest version of Dennett’s ‘big picture’ of the evolution of life and mind is frequent reference to ‘affordances’. An affordance is, roughly, a possibility for action for a creature in an environment. Given more than one possibility for action, a good question is: what will the creature actually do? I argue that affordances pose a problem of selection, and that a good general solution to this problem of mind-design is to implement a system of preferences.

    Fundamental laws and the completeness of physics
    International Studies in the Philosophy of Science 13 (3). 1999.
    The status of fundamental laws is an important issue when deciding between the three broad ontological options of fundamentalism (of which the thesis that physics is complete is typically a sub-type), emergentism, and disorder or promiscuous realism. Cartwright’s assault on fundamental laws which argues that such laws do not, and cannot, typically state the facts, and hence cannot be used to support belief in a fundamental ontological order, is discussed in this context. A case is made in defenc…Read more

    Time and the Decider
    Behavioral and Brain Sciences. forthcoming.
    Shadmehr and Ahmed’s book is a welcome extension of optimal foraging theory and neuroeconomics, achieved by integrating both with parameters relating to effort and rate of movement. Their most persuasive and prolific data comes from saccades, where times before and after decision are reasonably determinate. Skeletal movements are less likely to exhibit such tidy temporal organisation.

    Arguments that cognition or minds can be extended regularly invoke an analogy with Dawkins’ argument that phenotypes can be extended. I argue that there are two neglected ways in which those two boundary-breaking theses are complementary. Much of the argument of The Extended Phenotype concerns parasite phenotypes expressed in the behaviour of host organisms. But the options Dawkins considers for this extended manipulation are cognitively internalist. If we view cognition as extended, we can reco…Read more

    Abstract4E approaches to affective technology tend to focus on how ‘users’ manage their situated affectivity, analogously to how they help themselves cognitively through epistemic actions or using artefacts and scaffolding. Here I focus on cases where the function of affective technology is to exploit or manipulate the agent engaging with it. My opening example is the cigarette, where technological refinements have harmfully transformed the affective process of consuming nicotine. I proceed to d…Read more

    The Natural History of Desire
    South African Journal of Philosophy 34 (3): 304-313. 2015.
    Sterelny (2003) develops an idealised natural history of folk-psychological kinds. He argues that belief-like states are natural elaborations of simpler control systems, called detection systems, which map directly from environmental cue to response. Belief-like states exhibit robust tracking (sensitivity to multiple environmental states), and response breadth (occasioning a wider range of behaviours). The development of robust tracking and response-breadth depend partly on properties of the inf…Read more

    Our response amplifies our case for scientific realism and the unity of science and clarifies our commitments to scientific unity, nonreductionism, behaviorism, and our rejection of talk of “emergence.” We acknowledge support from commentators for our view of physics and, responding to pressure and suggestions from commentators, deny the generality supervenience and explain what this involves. We close by reflecting on the relationship between philosophy and science

    Physicalism as an empirical hypothesis
    Synthese 194 (9): 3347-3360. 2017.
    Bas van Fraassen claims that materialism involves false consciousness. The thesis that matter is all that there is, he says, fails to rule out any kinds of theories. The false consciousness consists in taking materialism to be cognitive rather than an existential stance, or attitude, of deference to the current content of science in matters of ontology, and a favourable attitude to completeness claims about the content of science at a time. The main argument Van Fraassen provides for saying that…Read more

    More philosophical effort is spent articulating evolutionary rationales for the development of belief-like capacities than for precursors of desires or preferences. Nobody, though, seriously expects naturally evolved minds to be disinterested epistemologists. We agree that world-representing states won’t pay their way without supporting capacities that prioritise from an organism’s available repertoire of activities in light of stored (and occurrent) information. Some concede that desire-like st…Read more

    Our point of departure is Russell’s (1913) argument for the ‘complete extrusion’ of the word ‘cause’ from the philosophical vocabulary. We argue that at least three different types of philosophical project concerning ‘cause’ should be carefully distinguished, and that failures to distinguish them lie at the root of some apparently recalcitrant problems. We call them the ‘cognitive’, the ‘scientific’ and the ‘metaphysical’.

    Why I am not an analytic philosopher
    South African Journal of Philosophy 27 (2): 153-163. 2008.
    From a certain simplistic and inaccurate, although regrettably popular, perspective philosophy, at least for the past few decades, is available only in two main flavours – analytic and continental. Some self-identified members of both camps are apt to endorse uncharitable caricatures of what the others are up to. Among the many lines of criticism that can be directed against this false dichotomy, I wish to focus on discussion of a broadly naturalistic orientation that rejects many of the commitm…Read more

    Bhaskar on Open and Closed Systems
    South African Journal of Philosophy 19 (3): 188-209. 2000.
    Bhaskar's articulation of his ‘transcendental realism' includes an argument for a form of causal emergence which would mean the rejection of physicalism, by means of rejecting the causal closure of the physical. His argument is based on an analysis of the conditions for closure, where closed systems manifest regular or Humean relations between events. Bhaskar argues that the project of seeking closure entails commitment to a strong reductionism, which in turn entails the impossibility of science…Read more

    Information processing and dynamical systems approaches are complementary
    Behavioral and Brain Sciences 25 (5): 639-640. 2002.
    Shanker & King (S&K) trumpet the adoption of a “new paradigm” in communication studies, exemplified by ape language research. Though cautiously sympathetic, I maintain that their argument relies on a false dichotomy between “information” and “dynamical systems” theory, and that the resulting confusion prevents them from recognizing the main chance their line of thinking suggests.

    More attention has been devoted to providing evolutionary accounts of the development of beliefs, or belief-like states, than for desires or preferences.

The argument is an application of the ‘environmental complexity thesis’ found in Godfrey-Smith and Sterelny, alt…Read more
