Locke: Substance

This essay examines Locke’s chapter “Of Identity and Diversity” (Essay 2.27) in the context of the series of chapters on ideas of relations (Essay 2.25–28) that precede and follow it. I begin by introducing Locke’s account of how we acquire ideas of relations. Next, I consider Locke’s general approach to individuation and identity over time before I show how he applies his general account of identity over time to persons and personal identity. I draw attention to Locke’s claim that “person” (...) is a forensic term and analyse his arguments for why the sameness of a human being and the sameness of a substance or soul are neither necessary nor sufficient for personal identity. Instead, Locke argues that personal identity consists in sameness of consciousness. Locke regards persons as moral agents who are accountable for their actions. If a person now is held accountable for a past action it is important that the person now is the same person as the person who did the action. This means that moral accountability presupposes personal identity. Additionally, it will be important to consider whether the person deserves reward or punishment for the action. Locke’s account of moral relations, which he develops in Essay 2.28, addresses this issue and I show how it supplements his account of persons and personal identity. (shrink)

My chapter examines Isaac Watts’s and Catharine Trotter Cockburn’s views concerning the metaphysics of the mind and their underlying accounts of powers and substances. In Philosophical Essays on Various Subjects Watts criticizes Locke’s account of substances and argues for his own preferred account of substance. Watts argues that there is no need to postulate an unknown substratum, as Locke does. Instead, Watts searches for a better explanation of what substances are. His proposal is that bodily substance just is solid extension (...) and that mental substance is identical with the power of thinking. This means that Watts believes that some powers can be substances. I will show how Watts defends his account of substances against various objections. Cockburn was not satisfied by Watts’s account of substance and disagrees with Watts’s understanding of powers. She believes that Watts is too quick to draw metaphysical conclusions. Cockburn takes seriously the limitations of human understanding and emphasizes that humans are ignorant about many metaphysical truths. I end by assessing the strengths and weaknesses of Watts’s and Cockburn’s accounts of powers and substances. (shrink)

In this paper, we intend to offer an interpretation about the explanation of the (relative) idea of pure substance in general on John Locke’s philosophy, from Thomas Reid’s notion of ‘natural suggestion’. To achieve this aim, after contextualizing Locke’s notion of pure substance in general and distinguishing it from the idea of particular substance (section 1), we explicit that Locke’s words about the source of the idea of the former in the mind (either empirical or rational) are ambiguous and inconclusive (...) (section 2). Then, we argue that the parallels between this idea and that of ‘relation’, as well as of ‘power’ do not assist in that answer, due to some problems we identify on them (section 3). Finally, we argue that the Reidian explanation for the source of the idea of ‘mind’, from the notion of ‘natural suggestion’ allows us to i) avoid those problems and ii) inasmuch as, according to this interpretation, the idea of pure substance in general would have an empirical source, Lockian empiricism would remain intact (section 4).

In this paper, I will argue that Locke is a substance dualist in the general sense, in that he holds that there are, independent of our classificatory schema, two distinct kinds of substances: wholly material ones and wholly immaterial ones. On Locke’s view, the difference between the two lies in whether they are solid or not, thereby differentiating him from Descartes. My way of establishing Locke as a general substance dualist is to be as minimally committal as possible at the (...) outset, especially with respect to the classic debates on Locke’s positions in this domain, including those concerning substrata, real essences, and the like. Nonetheless, I show that minimal commitments about Locke’s primary/secondary quality distinction are sufficient to derive some substantive conclusions about his positions on these issues, as well as that he is a general substance dualist.

Bu tezde töz sorununun ampirist filozoflar tarafından nasıl ele alındığı üzerinde durulacaktır. Varlık ve bilgi felsefesini tek bir potada eriten ve felsefenin en eski sorunlarından bir tanesi olan töz sorunu on sekizinci yüzyıl düşünürleri olan Locke, Berkeley ve Hume’un görüşleri çerçevesinde incelenmeye çalışılacaktır. Bu konunun belirlenmesinde töz sorununun felsefenin başlangıcından günümüze kadar devam eden bir sorun olması etkili olmuştur.

In the Essay, Locke refers to the ordinary-sized natural things as ‘particular sorts of Substances’ (2.23), whereas the ‘three sorts of Substances’ (2.27) are more metaphysically laden sorts: God, finite spirits, and fundamental material particles. He posits the much-contested ‘substratum’ in each particular sort of substance but not any of the three sorts. It should also be noted that his list of the particular sorts includes ‘men’. In regard to this nobler sort, he refers to a further classification – viz., (...) ‘the Substance of spirit’ and ‘the Substance of the body’ – only in terms of their nominal essence. A naturalistic, nominalist approach is deeply entrenched in his account of the human-related sorts as well. In this chapter, I shall explore how Locke develops a theory of substance in the Essay that is less metaphysical, more naturalistic, and epistemically humbler than those of his rationalist contemporaries.

The ancient theory of substance and accident is supposed to make sense of complex unities in a way that respects both their unity and their complexity. On Hume’s view such complex unities are only fictitiously unities. This result follows from his thoroughgoing critique of the theory of substance. I will characterize the theory Hume is critiquing as it is presented in Locke, presupposing what Bennett calls the “Leibnizian interpretation.” Locke uses the word ‘substance’ in two senses. Call substance in the (...) first sense “individual substance” and in the second sense “pure substance.” I will discuss the seven main parts of Hume’s view: (I) that we have no idea of pure substance, (II) that there is no complex individual substance, except in a loose sense, (III) that the fiction of complex individual substance arises in a way parallel to that of the fiction of identity through time, and (IV) results in the fiction of pure substance, (V) that simple qualities and perceptions satisfy the definition of individual substance, (VI) that there is no such thing as inherence, and (VII) that there is no such thing as pure substance. Hume’s views on substance are often mentioned without being discussed in detail. Kemp Smith, Stroud, and Garrett, for example, mostly summarize various claims of Hume in the course of expounding on his theory of the idea of personal identity. In contrast, I will attempt to present a systematic treatment of Hume on substance as a refutation of Locke. (shrink)

The world is occupied by many and varied things. What constitutes their thingness? In the Essay, Locke addresses this question in Book II, Chapter xxiii, titled ‘Of our Complex Ideas of Substance’, wherein the much-contested definition of ‘substratum’ appears—‘a supposed but unknown support of the Qualities’. Most significant in this definition are the dual qualifiers that Locke uses: ‘supposed’ and ‘unknown’. This paper examines this two-qualifier definition, illuminating the historical and philosophical significance it may have. There have been two rival (...) readings. The first takes Locke’s substratum to be a bare substratum; and the second identifies it with what Locke terms as ‘real essence’—i.e. ‘a real Constitution of the insensible Parts’. Critically reviewing these two major interpretations, I attribute to Locke a type of functionalism, according to which the status of a substratum is determined by its functional role of ‘uniting’ a bundle of qualities into an individual substance.

The goal of this paper is to critically examine the objections of John Locke’s contemporaries against the theory of substance or substratum. Locke argues in Essay that substratum is the bearer of the properties of a particular substance. Locke also claims that we have no knowledge of substratum. But Locke’s claim about our ignorance as to what substratum is, is contentious. That is, if we don’t know what substratum is, then what is the point of proposing it as a bearer (...) of properties? This question underlies the criticism Locke’s contemporaries raise against the notion of substratum. In section I, I lay out the context for Locke’s theory of substratum by pointing out his main motivation in proposing his theory. In section II, I give a brief analysis of the theory of substratum. In section III, I discuss the objections of Locke’s contemporaries against the theory of substratum.1 I focus on Edward Stillingfleet, Lee Henry, G. W. Leibniz and John Sergeant. In section IV, I conclude that there is no warrant to dismiss Locke’s theory of substance. (shrink)

Locke’s conception of substance in general or substratum has two relatively widespread interpretations. According to one, substance in general is the bearer of properties, a pure subject, something which sustains properties but itself has no properties. I will call this interpretation traditional, because it has already been formulated by Leibniz. According to the other interpretation, substance is general is something like real essence: an underlying structure which is responsible for the fact that certain observable properties form stable, recurrent clusters. I (...) will argue that both interpretation are partly right, and what is good in them can be reconciled. The traditional interpretation captures the purpose and signficanc of the idea of substance in general, i.e. the reason why Locke says we have this idea. The real essence view is right about the real world counterpart of the idea, i.e. what sort of entity the idea corresponds to. The paper starts with a review of the strengths and weaknesses of the rival interpretations (I, II). Then I examine which part of the traditional interpretation can be sustained in light of the problems it faces (III). Thereafter I will show that the part of the traditional interpretation which can be sustained cannot stand on its own and needs to be supplemented at one point, and the real essence view can provide what is needed. This, as it were, mixed interpretation will be supported by sketching an argument which is plausible within the context of Locke’s teachings and which explains how Locke could have arrived from the view which the traditional interpretation correctly attributes to him to the view which the real essence interpretation takes him to espouse (IV). The two problematic points in this argument will be taken up in the following two sections. (V, VI). Finally, I will provide some evidence from the Drafts for Locke’s identification of substance and essence (VII). (shrink)

I defend an interpretation of Locke’s remarks on substratum according to which substrata not only have sensible qualities but are just familiar things and stuffs: horses, stones, gold, wax, and snow. The supporting relation that holds between substrata and the qualities that they support is simply the familiar relation of having, or instantiating, which holds between a particular substance and its qualities. I address the obvious objection to the interpretation -- namely, that it cannot be reconciled with Locke’s claim that (...) the idea substratum is an obscure, confused idea of we know not what -- and I identify numerous textual parallels between Locke's discussions of substrata and particular substances which strongly support the deflationary interpretation.

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.

Locke's claims about the "inadequacy" of substance-ideas can only be understood once it is recognized that the "sort" represented by such an idea is not wholly determined by the idea's descriptive content. The key to his compromise between classificatory conventionalism and essentialism is his injunction to "perfect" the abstract ideas that serve as "nominal essences." This injunction promotes the pursuit of collections of perceptible qualities that approach ever closer to singling out things that possess some shared explanatory-level constitution. It is (...) in view of this norm regulating natural-historical inquiry that a substance-idea represents a sort for which some such constitution serves as the "real essence," i.e. as that on which all the sort's characteristic "properties" depend.
