Individualism in psychology is the view that mental states must be individuated so as to be intrinsic to particular individuals. This view has been thought to impose an intuitive and plausible constraint on explanation in psychology. The dissertation is a sustained examination of individualism, especially with respect to its role in psychological explanation. My particular interest is in showing that individualism is not a constraint on psychology which follows from either psychology's scientific nature, or from the nature of causation or materialism. ;Apart from an extended introduction in which I explain why individualism is both a substantive and plausible constraint on taxonomy and explanation in psychology, the dissertation has three parts. The aim of Part One is to reconstruct and critically discuss three influential, recent arguments for individualism: an a priori argument , a empirical argument , and a methodological argument. I argue that each of these arguments is unsound and should be rejected. In an Appendix to Chapter 2 I argue that individualism does not follow from the causal theory of properties. ;In Part Two I turn to examine individualism itself. The aim of this part of the dissertation is to address the view that psychological kinds and explanations which are not individualistic cannot be part of an adequate account of mental causation. Chapter 5 both responds to particular charges that have been made about denials of individualism, and articulates and criticizes a central intuition about the local nature of causation from which individualism has sometimes been thought to follow. Chapter 6 focusses on folk psychology and attempts to show how one can view folk psychological explanation as unproblematically causal even though it is not individualistic. ;In Part Three I develop a core case against individualism using the concepts of causal depth and theoretical appropriateness, concepts which form the basis for two constraints on good causal explanations. I argue that individualism should be rejected because individualistic explanations of behavior, including individualistic psychological explanations, are not always the causally deepest or most theoretically appropriate explanations available.

Philosophical exploration of individualism and externalism in the cognitive sciences most recently has been focused on general evaluations of these two views (Adams & Aizawa 2008, Rupert 2008, Wilson 2004, Clark 2008). Here we return to broaden an earlier phase of the debate between individualists and externalists about cognition, one that considered in detail particular theories, such as those in developmental psychology (Patterson 1991) and the computational theory of vision (Burge 1986, Segal 1989). Music cognition is an area in the cognitive sciences that has received little attention from philosophers, though it has relatively recently been thrown into the externalist spotlight (Cochrane 2008, Kruger 2014, Kersten forthcoming). Given that individualism can be thought of as a kind of paradigm for research on cognition, we provide a brief overview of the field of music cognition and individualistic tendencies within the field (sections 2 and 3) before turning to consider externalist alternatives to individualistic paradigms (section 4-5) and then arguing for a qualified form of externalism about music cognition (section 6).

Vision constitutes an interesting domain, or range of domains, for debate over the extended mind thesis, the idea that minds physically extend beyond the boundaries of the body. In part this is because vision and visual experience more particularly are sometimes presented as a kind of line in the sand for what we might call externalist creep about the mind: once all reasonable concessions have been made to externalists about the mind, visual experience marks a line beyond which lies a safe haven for individualists. Here I want to put a little more pressure on such a view of visual experience, as well as to offer a more constructive, positive argument in defense of the idea of extended vision.

Individual organisms are obvious enough kinds of things to have been taken for granted as the entities that have many commonly attributed biological and psychological properties, both in common sense and in science. The sorts of morphological properties used by the folk to categorize individual animals and plants into common sense kinds (that's a dog; that's a rose), as well as the properties that feature as parts of phenotypes, are properties of individual organisms. And psychological properties, such as believing that taxes are too low, and remembering the last seven digits you read in the phone book, are likewise properties of individual organisms.

John Locke is known within anthropology primarily for his empiricism, his views of natural laws, and his discussion of the state of nature and the social contract. Marilyn Strathern and Marshall Sahlins, however, have offered distinctive, novel, and broad reflections on the nature of anthropological knowledge that appeal explicitly to a lesser-known aspect of Locke’s work: his metaphysical views of relations. This paper examines their distinctive conclusions – Sahlins’ about cultural relativism, Strathern’s about relatives and kinship – both of which concern the objectivity of anthropological knowledge. Although Locke’s own views of relations have been neglected by historians of philosophy in the past, recent and ongoing philosophical discussions of Locke on relations create a productive trading zone between philosophy and anthropology on the objectivity of anthropological knowledge that goes beyond engagement with the particular claims made by Sahlins and Strathern.

This paper distinguishes and critiques several forms of pluralism about the levels of selection, and introduces a novel way of thinking about the biological properties and processes typically conceptualized in terms of distinct levels. In particular, "levels" should be thought of as being entwined or fused. Since the pluralism discussed is held by divergent theorists, the argument has implications for many positions in the debate over the units of selection. And since the key points on which the paper turns apply beyond this specific issue, the paper may prove of general interest in thinking about the metaphysics of science.

Dominant views of personal identity in philosophy take some kind of psychological continuity or connectedness over time to be criterial for the identity of a person over time. Such views assign psychological states, particularly those necessary for narrative memory of some kind, special importance in thinking about the nature of persons. The extended mind thesis, which has generated much recent discussion in the philosophy of mind and cognitive science, holds that a person’s psychological states can physically extend beyond that person’s body. Since “person” is a term of both metaphysical and moral significance, and discussions of both extended minds and personal identity have often focused on memory, this article explores the relevance of extended cognition for the identity of persons with special attention to neuroethics and memory.
