Locke: Identity

William Molyneux (1656–1698) was an Irish experimental philosopher and politician, who played a major role in the intellectual life in seventeenth-century Dublin. He became Locke’s friend and correspondent in 1692 and was probably Locke’s philosophically most significant correspondent. Locke approached Molyneux for advice for revising his Essay concerning Human Understanding as he was preparing the second and subsequent editions. Locke made several changes in response to Molyneux’s suggestions; they include major revisions of the chapter ‘Of Power’ (2.21), the addition of (...) the chapter ‘Of Identity and Diversity’ (2.27), and the addition of the so-called Molyneux Problem (2.9.8). Molyneux repeatedly requested that Locke develops his views on morality. Additionally, their correspondence turned to questions concerning education and Molyneux’s keen interest in the topic likely prompted Locke to publish Some Thoughts Concerning Education in 1693. Moreover, Molyneux drew on Locke’s anonymously published Two Treatises of Government in his The Case of Ireland’s Being Bound by Acts of Parliament in England, Stated, which was first published in the spring of 1698. Molyneux revealed Locke’s authorship of Two Treatises against Locke’s will, yet their friendship continued until Molyneux’s untimely death in October 1698. (shrink)

John Locke accepts that every perception gives me immediate and intuitive knowledge of my own existence. However, this knowledge is limited to the present moment when I have the perception. If I want to understand the necessary and sufficient conditions of my continued existence over time, Locke argues that it is important to clarify what ‘I’ refers to. While we often do not distinguish the concept of a person from that of a human being in ordinary language, Locke emphasizes that (...) this distinction is important if we want to engage with questions of identity over time. According to Locke, persons are thinking intelligent beings who can consider themselves as extended into the past and future and who are concerned for their happiness and accountable for their actions. Moreover, for Locke a self is a person, considered from a first-personal point of view. I show that the concept of self that he develops in the context of his discussion of persons and personal identity is richer and more complex than the I-concept that he invokes in his version of the cogito. I further argue that Locke’s moral and religious views explain why he emphasizes the need for a conceptual distinction between persons and human beings. In the final section I turn to the reception of Locke’s view by some of his early critics and defenders, including Elizabeth Berkeley Burnet, an anonymous author, and Catharine Trotter Cockburn.

Catharine Trotter Cockburn (1679- 1749) fu poetessa, drammaturga e filosofa. La vivacità intellettuale e la forte determinazione le permisero di aggirare il pregiudizio di genere e di sottrarsi alle dinamiche di marginalizzazione femminile tipiche dell’età moderna. Pur celandosi dietro l’anonimato, Cockburn prese parte attiva al dibattito filosofico del tempo, intervenendo soprattutto in materia di morale. Le sue opere filosofiche, scritte in difesa di Locke o di Clarke, custodiscono, nonostante il dichiarato intento apologetico, tratti di originalità e indipendenza, particolarmente evidenti nella (...) teoria dell’obbligo morale, nell’interpretazione modale della dottrina lockeana d’identità personale, nell’ipotesi di una natura ontologica dello spazio.

This paper gives three arguments for why Lockean persons must be modes rather than substances.

According to Locke, appropriation is a precondition for moral responsibility and thus we can expect that it plays a distinctive role in his theory. Yet it is rare to find an interpretation of Locke’s account of appropriation that does not associate it with serious problems. To make room for a more satisfying understanding of Locke’s account of appropriation we have to analyse why it was so widely misunderstood. The aim of this paper is fourfold: First, I will show that Mackie’s (...) and Winkler’s interpretations that have shaped the subsequent discussion contain serious flaws. Second, I will argue that the so-called appropriation interpretation —that is the view that appropriation is meant to provide alternative persistence conditions for persons—lacks support. Third, I will re-examine Locke’s texts and argue that we can come to a better understanding of his notion of appropriation in the Essay if we interpret it in analogy to his account of appropriation in Two Treatises. Fourth, I will offer a more fine-grained interpretation of the role of appropriation in relation to persistence conditions for persons. I conclude by showing that the advantage of this proposal is that it reconciles interpretations that have commonly been thought to be inconsistent. (shrink)

Hume’s theory of personal identity is developed in response to Locke’s account of personal identity. Yet it is striking that Hume does not emphasize Locke’s distinction between persons and human beings. It seems even more striking that Hume’s account of the self in Books 2 and 3 of the Treatise has less scope for distinguishing persons from human beings than his account in Book 1. This is puzzling, because Locke originally introduced the distinction in order to answer questions of moral (...) accountability and Hume’s discussion of the self in Book 2 provides the foundation of his moral theory in Book 3. In response to the puzzle I show that Locke and Hume hold different moral and religious views and these differences are important to explain why their theories of personal identity differ. (shrink)

Shelley Weinberg’s Consciousness in Locke builds on her previous journal articles and makes significant contributions to John Locke scholarship by offering the first systematic study of consciousness throughout Locke’s Essay. According to Weinberg, consciousness for Locke is self-referential, non-evaluative awareness internal to every thought or perception. She argues that once we realize the complexity of any perception—namely that every perception involves, “at the very least, an act of perception, an idea perceived, and consciousness ” —we can see that Locke’s conception (...) of consciousness connects important themes in his philosophical psychology, namely his theory of...

Locke and Leibniz on Substance gathers together papers by an international group of academic experts, examining the metaphysical concept of substance in the writings of these two towering philosophers of the early modern period. Each of these newly-commissioned essays considers important interpretative issues concerning the role that the notion of substance plays in the work of Locke and Leibniz, and its intersection with other key issues, such as personal identity. Contributors also consider the relationship between the two philosophers and contemporaries (...) such as Descartes and Hume. (shrink)

This new volume in the successful Oxford Readings in Philosophy series presents a selection of the best recent articles on the main topics in Locke's philosophy. These include: innate ideas, ideas and perception, primary and secondary qualities, free will, substance, personal identity, language, essence, knowledge, and belief. The authors include some of the world's leading Locke scholars, and their essays exemplify the best - and most accessible - recent scholarship on Locke, making the volume essential for students and specialists.

In a well-known paper, Reginald Jackson expresses a sentiment not uncommon among readers of Locke: “Among the merits of Locke’s Essay…not even the friendliest critic would number consistency.”2 This unflattering opinion of Locke is reiterated by Maurice Mandelbaum: “Under no circumstances can [Locke] be counted among the clearest and most consistent of philosophers.”3 The now familiar story is that there are innumerable inconsistencies and internal problems contained in Locke’s Essay. In fact, it is probably safe to say that there is (...) not another canonical, well-respected, and seminal philosopher whose work is so widely thought to be swarming with inconsistencies. I, however, do not think that the common, unflattering view of Locke is accurate as a general view of the Essay. But despite my wishes to the contrary, I do believe that Locke’s chapter ‘Of Identity and Diversity’ (2.27)4 leads to (at least) one intractable problem, a problem that is the subject of this paper.

The current consensus in Locke scholarship is that Robert Boyle anticipated Locke's thesis that classification into species is the arbitrary work of the understanding. In fact, according to Michael Ayers, inter alia, not only did Boyle and Locke both think that classification is the workmanship of the understanding but that this thesis follows directly from the mechanical hypothesis itself. In this paper I argue that this reading of Boyle is mistaken: Locke's thesis on classification was not anticipated by Boyle. I (...) will do this by showing that Boyle's account of classification is not Locke's, but is a more realist view of natural species employing a mechanically respectable account of natural forms.

In his Essay Concerning Human Understanding, Locke famously introduces both the problem of personal identity over time and a controversial solution to it. The problem is to provide a criterion for when a person, A, at a time, t, is the same as a person, B, at a later time, t' . Locke's proposal that A at t is the same person as B at t ' just in case B at t' is conscious of some episode in the mental (...) life of A at t has drawn considerable criticism and given rise to a specialized area of research in metaphysics and the philosophy of mind. I argue that many of what have become standard attacks on Locke's theory of personal identity are vitiated because they divorce Locke's discussion of personal identity from the rest of his argument in the Essay. The criticisms attack, in effect, a consequence of Locke's discussion but not the epistemological assumptions that drive it. In particular, many of the criticisms ignore Locke's empiricist critique of the general idea of substance, which is of central importance in understanding how Locke arrives both at the problem of personal identity and his response to it.

In this dissertation, I position John Locke's problem of personal identity in relation to three distinct philosophical approaches taken in the Seventeenth Century to the problems of personal immortality and the afterlife. Locke considers in his treatment of identity three philosophical accounts of personal immortality, viz., Cartesian dualism, Hobbesian materialism, and the Cambridge Platonism of Henry More, and rejects each. In separate chapters, I develop each of these accounts focusing on ontology, theories of perception and memory, relation to Aristotelian thinkers (...) , and understandings of theology and theological doctrines. In each chapter, I examine Locke's treatment of each philosophical approach in his analysis of personal identity. Locke rejects the "substance" accounts and replaces them with an analysis of consciousness and memory that can survive the change of material and immaterial substance integral to his understanding of the doctrines of bodily resurrection and personal immortality. I argue in the final chapter that once situated in its appropriate context, Locke exhibits resources on which to draw in response to three commonly considered fatal objections made to his theory by philosophers such as Thomas Reid and Bishop Joseph Butler.

The subject of this dissertation is John Locke's concept of a person, his theory of personal identity, and the implications of both for the bioethical debate concerning brain death and advance directives. I offer an interpretation of Locke that emphasizes the phenomenology of conscious experience and the narrative quality of the life of a person. This interpretation supports a neocortical formulation of brain death, and affirms the moral authority of advance directives. ;I begin by emphasizing Locke's fundamental distinction between 'man' (...) and 'person,' or between human biological life and human personal life. Through this distinction Locke identifies the capacity for personhood as the distinctive feature of human beings. I then identify the necessary and sufficient conditions for personhood according to Locke as rational, continuing, concerned, self-consciousness . These essential elements of personhood indicate, contrary to the traditional interpretation, that Locke's theory of personal identity is not simply a memory theory, or one which reduces persons to mental states and their causal connections. Continuing consciousness is a complex phenomenon that has cognitive and conative dimensions. The critical perspective from which to consider Lockean persons is the first person rather than the third. ;I combine Locke's "man/person" distinction and his identification of RCCSC as the necessary and sufficient conditions for personhood to construct an argument in support of neocortical death, by which I mean the permanent loss of the capacity for conscious experience. The capacity for conscious experience is that feature of a person that is so essential to it that its permanent loss should be deemed to constitute death. ;A moral and legal challenge of advance directives has been launched by those who advocate the "neo-Lockean" view of persons associated with Derek Parfit. I defend the authority of advance directives as a form of prospective autonomy that would find favor with Locke. While Locke's stringent criteria of personhood might deny that status to the profoundly demented, Locke would affirm the right of their formerly competent selves to determine the treatment that they receive.

Locke defined a person as ‘a thinking intelligent being, that has reason and reflection, and can consider itself as itself, the same thinking thing, in different times and places” . To many who have been excited by the same thought as Locke, continuity of consciousness has seemed to be an integral part of what we mean by a person. The intuitive appeal of the idea that to secure the continuing identity of a person one experience must flow into the next (...) experience in some ‘stream of consciousoness” is evidenced by the number of attempts in the so-called constructionalist tradition to explain continuity of consciousness in terms of memory, and then build or reconstruct the idea of a person with these materials. The philosophical difficulty of the idea is plain from the failure of these attempts. Hindsight suggests this was as inevitable as the failure of the attempt to make bricks from straw alone—and as a failure just as uninteresting. Which is not to deny that the memory theorist might get from it a sense that some of the difficulties in his programme have arisen from his leaving flesh and bones, the stuff of persons, out of his construction.

john locke argues that personal identity consists in sameness of consciousness, and he maintains that any other theory of personal identity would lead to "great Absurdities".1 This statement intimates that Locke thought carefully about alternative conceptions of personal identity and their problems. In this paper, I argue that, by understanding Locke's account of personal identity in the context of metaphysical and religious debates of his time, especially debates concerning the afterlife and the state of the soul between death and resurrection, (...) we can reveal the strengths of his view and show how his account of personal identity in terms of sameness of consciousness has the resources to avoid...

In line with the empiricist project, Locke tries to describe how unconscious encounters with environment yield to the emergence of consciousness. For Locke the self is identical with consciousness and consciousness is accessible empirically. As far as the identity of human is concerned, identity of the self depends on the consciousness of the person. The person is identical to himself to the extent that he is aware of his own perceptions and thinking. The range of the person’s memory sets the (...) limits of consciousness. According to Locke, consciousness is an element that accompanies all acts of thinking including act of recollection. Such accompanying consciousness constitutes the form of the identity of the self, whereas memory-ideas may be considered the content of consciousness. Therefore, it is this formal constitutive element that provides constancy of the idea of the self. If so, then it can be claimed that Locke’s approach to the question of the self results in admitting the truth of what he intends to reject and it is self-defeating; this is to say that, Locke’s methodology pushes him to adopt a Platonic-Aristotelian formal theory of identity in general and of personal identity in particular.
