    Intention, Action, and De Se Indexicality
    Acta Analytica 1-16. forthcoming.
    The view that first-person (de se) mental content is essential to the explanation of action in general is a strong essential indexicality thesis. A weaker essential indexicality claim is that de se mental content is an essential ingredient of intentional action. An argument by Bermúdez for the former thesis and an argument from Babb in support of the latter are discussed in Section 2, and for reasons presented there it seems that both arguments are unsound and the conclusions are false as well. …Read more

    Subjective experience and points of view
    Journal of Philosophical Research 18 25-36. 1993.
    Thomas Nagel contends that facts regarding the qualitative character of conscious experience can be grasped from only a single point of view. This feature, he claims, is what renders conscious experience subjective in character, and it is what makes facts about the qualitative experience subjective facts. While much has been written regarding the ontological implications of the ‘point of view account’ relatively Iittle has been said on whether the account itself successfully defines the subjecti…Read more

    Animalism with Psychology
    Dialectica. forthcoming.
    Here I develop an account of our persistence that accommodates each of the following compelling intuitions: (i) that we are animals, (ii) that we existed prior to the onset of whatever psychological capacities are necessary for personhood, and we can continue to exist with the loss of those and other psychological capacities, (iii) that with suitable psychological continuity, the person goes with the brain/cerebrum in remnant person and brain/cerebrum transplant cases, and (iv) that it is possib…Read more

    Who are “we”?: Animalism and conjoined twins
    Analytic Philosophy 64 (4): 422-442. 2023.
    Various cases of conjoined twinning have been presented as problems for the animalist view that we are animals. In some actual and possible cases of human dicephalus that have been discussed in the literature, it is arguable that there are two persons but only one human animal. It is also tempting to believe that there are two persons and one animal in possible instances of craniopagus parasiticus that have been described. Here it is argued that the animalist can admit that these are cases in wh…Read more

    Maximality, Function, and the Many
    Metaphysica 20 (2): 175-193. 2019.
    In the region where some cat sits, there are many very cat-like items that are proper parts of the cat (or otherwise mereologically overlap the cat) , but which we are inclined to think are not themselves cats, e.g. all of Tibbles minus the tail. The question is, how can something be so cat-like without itself being a cat. Some have tried to answer this “Problem of the Many” (a problem that arises for many different kinds of things we regularly encounter, including desks, persons, rocks, and clo…Read more

    Whether Mentality Is "Higher-Level"
    Philosophical Inquiry 24 (3-4): 65-76. 2002.
  • Behavior and Mental Content
    Dissertation, Syracuse University. 1991.
    Behaviorism is dead! Or so claim the majority of philosophers today. I aim to show that they are wrong. ;I defend philosophical behaviorism as an account of our ordinary, pretheoretical concepts pertaining to the intentional aspects of mind. The theory purports to explain in purely behavioral terms what it is for a mental state to be a belief, a desire or a thought, and what it is about the state that gives it its content. Like Rylean behaviorism, it does not seek to characterize intentional sta…Read more

    Physicalism and the Mind
    Springer. 2014.
    This book addresses a tightly knit cluster of questions in the philosophy of mind. There is the question: Are mental properties identical with physical properties? An affirmative answer would seem to secure the truth of physicalism regarding the mind, i.e., the belief that all mental phenomena obtain solely in virtue of physical phenomena. If the answer is negative, then the question arises: Can this solely in virtue of relation be understood as some kind of dependence short of identity? And ans…Read more

    Mental Excess and the Constitution View of Persons
    Philosophical Papers 46 (2): 211-243. 2017.
    Constitution theorists have argued that due to a difference in persistence conditions, persons are not identical with the animals or the bodies that constitute them. A popular line of objection to the view that persons are not identical with the animals/bodies that constitute them is that the view commits one to undesirable overpopulation, with too many minds and too many thinkers. Constitution theorists are well aware of these overpopulation concerns and have gone a long way toward answering th…Read more

    Surviving death: how to refute termination theses
    Inquiry: An Interdisciplinary Journal of Philosophy 61 (2): 178-197. 2018.
    When deciding how ‘death’ should be defined, it is helpful to consider cases in which vital functions are restored to an organism long after those vital functions have ceased. Here I consider whether such restoration cases can be used to refute termination theses. Focusing largely on the termination thesis applied to human animals, I develop a line of argument from the possibility of human restoration to the conclusion that in many actual cases, human animals continue to exist after they die. Th…Read more

    Intrinsic/Extrinsic: A Relational Account Defended
    In Robert M. Francescotti (ed.), Companion to Intrinsic Properties, De Gruyter. pp. 175-198. 2014.
    In "How to Define Intrinsic Properties" I offered a relational account of the intrinsic/extrinsic distinction. The basic idea is that F is an intrinsic property of an item x just in case x’s having F consists entirely in x’s having certain internal properties, where an internal property is one whose instantiation does not consist in one’s relation to any distinct items (items other than oneself and one’s proper parts). I still think that this relational analysis is largely correct, and here I pr…Read more

    Realization and Physicalism
    Philosophical Psychology 23 (5): 601-616. 2010.
    Melnyk provides a rigorous analysis of the notion of realization with the aim of defining Physicalism. It is argued here that contrary to Melnyk's Realization Physicalism, the idea that mental phenomena are realized by physical phenomena fails to capture the physicalist belief that the former obtain in virtue of the latter. The conclusion is not that Physicalism is false, but that its truth is best explained with some notion other than realization in Melnyk's sense. I also argue that the problem…Read more

    Fetuses, corpses and the psychological approach to personal identity
    Philosophical Explorations 8 (1): 69-81. 2005.
    Olson (1997a) tries to refute the Psychological Approach to personal identity with his Fetus Argument, and Mackie (1999) aims to do the same with the Death Argument. With the help of a suggestion made by Baker (1999), the following discussion shows that these arguments fail. In the process of defending the Psychological Approach, it is made clear exactly what one is and is not committed to as a proponent of the theory

    The problem of animal pain and suffering
    In Justin McBrayer Daniel Howard-Snyder (ed.), The Blackwell Companion to the Problem of Evil, Wiley. pp. 113-127. 2013.
    Here I discuss some theistic responses to the problem of animal pain and suffering with special attention to Michael Murray’s presentation in Nature Red in Tooth and Claw. The neo-Cartesian defenses he describes are reviewed, along with the appeal to nomic regularity and Murray’s emphasis on the progression of the universe from chaos to order. It is argued that despite these efforts to prove otherwise the problem of animal suffering remains a serious threat to the belief that an all-powerful, al…Read more

    The problem of extras and the contingency of physicalism
    Philosophical Explorations 17 (2): 241-254. 2014.
    Perhaps all concrete phenomena obtain solely in virtue of physical phenomena. Even so, it seems that the world could have been otherwise. It seems that physicalism, if true, is contingently true. In fact, many believe that the actual truth of physicalism allows metaphysically possible worlds duplicating the actual world in all physical respects while containing immaterial extras, e.g. ghosts, spirits, or Cartesian souls, that no physicalist would believe actually exist. Here I focus on physicali…Read more

    Ontological physicalism and property pluralism: Why they are incompatible
    Pacific Philosophical Quarterly 81 (4): 349-362. 2000.
    To earn the title “ontological physicalist,” one must endorse an entailment thesis of the following sort: the physical properties that are had, together with the causal laws, determine which higher-level properties are had. I argue that if this thesis is to capture all that is essential to physicalist intuitions, the relevant set of causal laws must be restricted to purely physical laws. But then it follows that higher-level properties are physical properties. The conclusion is that one cannot c…Read more

    Emergence
    Erkenntnis 67 (1). 2007.
    Here I offer a precise analysis of what it takes for a property to count as emergent. The features widely considered crucial to emergence include novelty, unpredictability, supervenience, relationality, and downward causal influence. By acknowledging each of these distinctive features, the definition provided below captures an important sense in which the whole can be more than the sum of its parts

    Mere Cambridge Properties
    American Philosophical Quarterly 36 (4): 295-308. 1999.
    The predicates 'is outgrown by Theaetetus,' 'is 300 miles west of a lemur,' and 'is such that 9 is odd' denote properties, but there is a sense in which these properties are not genuine features of the objects that have them. The fact that we find these mere-Cambridge properties odd has something to do with their relational character. But relationality in itself is not an adequate criterion for property-genuineness for there are many relational properties that do not qualify as mere-Cambridge. T…Read more
  • What multiple realizability does not show
    Journal of Mind and Behavior 18 (1): 13-28. 1997.
    It is widely held that psychological theories cannot be reduced to those of the natural sciences. Perhaps the most common reason for rejecting psycho-physical reduction is the belief that mental properties are multiply realizable--i.e., that events of different physical types might realize the same mental property. While the multiple realizability argument has had its share of criticism, its major flaw has been overlooked. I aim to show the real reason why the argument fails and why multiple rea…Read more

    Higher-order thoughts and conscious experience
    Philosophical Psychology 8 (3): 239-254. 1995.
    For nearly a decade, David Rosenthal has proposed that a mental state M of a creature C is conscious just in case C has a suitable higher-order thought directed toward M. While this theory has had its share of criticism in recent years, I believe that the real difficulties have been ignored. In this essay, I show that the presence of a higher order is insufficient for conscious experience, even if we suppose that the thought satisfies the constraints that Rosenthal lists . The only way Rosenthal…Read more
  • Understanding physical realization (and what it does not entail)
    Journal of Mind and Behavior 23 (3): 279-292. 2002.
    The notion of realization is defined so that we can better understand what it means to say that mentality is physically realized. It is generally thought that physical properties realize mental properties (thesis PR). The definitions provided here support this belief, but they also reveal that mental properties can be viewed as realizing physical properties. This consequence questions the value of PR in helping us capture the idea that mental phenomena are dependent upon (i.e., obtain by virtue …Read more

    Property dualism without substance dualism?
    Philosophical Papers 30 (2): 93-116. 2001.
    Substance dualism is widely rejected by philosophers of mind, but many continue to accept some form of property dualism. The assumption here is that one can consistently believe that (1) mental properties are not physical properties, while denying that (2) mental particulars are not physical particulars. But is this assumption true? This paper considers several analyses of what makes something a physical particular (as opposed to a non-physical particular), and it is argued that on any plausible…Read more

    Externalism and Marr's theory of vision
    British Journal for the Philosophy of Science 42 (June): 227-38. 1991.
    According to one brand of 'externalism', cognitive theories should individuate mental content 'widely'--that is, partly in terms of environmental features. David Marr's theory of vision is often cited in support of this view. Many philosophers (most notably, Tyler Burge) regard it as a prime example of a fruitful cognitive theory that widely individuates the representations it posits. I argue that, contrary to popular belief, Marr's theory does not presuppose an externalist view of mental conten…Read more

    Psychological Continuity, Fission, and the Non-Branching Constraint
    Pacific Philosophical Quarterly 89 (1): 21-31. 2008.
    Abstract: Those who endorse the Psychological Continuity Approach (PCA) to analyzing personal identity need to impose a non-branching constraint to get the intuitively correct result that in the case of fission, one person becomes two. With the help of Brueckner's (2005) discussion, it is shown here that the sort of non-branching clause that allows proponents of PCA to provide sufficient conditions for being the same person actually runs contrary to the very spirit of their theory. The problem i…Read more
