Locke on Persons and Other Kinds of Substances

Locke's commentators are divided about whether Locke thinks that the idea of a person is a substance idea or a mode idea. I use Locke's theory of kinds to argue for an intermediate interpretation on which the idea of a person is a substance idea that contains a mode idea. As a result, while proponents of the substance interpretation correctly claim that ‘person’ designates a kind of substance, proponents of the mode interpretation are nonetheless correct in insisting that mode ideas play an important role in Locke's account of persons and personal identity.     

Emilie du Châtelet on the Existence and Nature of God: An Examination of Her Arguments in Light of Their Sources

Many commentators have suggested that the metaphysical portions of Emilie du Châtelet's Institutions de physique are a mere retelling of Leibniz's views. I argue that a close reading of the text shows that du Châtelet's cosmological argument and discussion of God's nature contains both Lockean and Leibnizian elements. I discuss where she follows Locke in her arguments, what Leibnizian elements she brings in, and how this enables her to avoid some of the mistakes commonly attributed to Locke's formulation of the cosmological argument. I show that while du Châtelet accepts the causal principle ex nihilo nihil fit, she does not utilize Locke's stronger causal principle. I also discuss her use of the principle of sufficient reason in both improving the Lockean cosmological argument and in proving the attributes of God.     

God,Mixed Modes,and Natural Law: An Intellectualist Interpretation of Locke's Moral Philosophy

The goal of this paper is to explicate the theological and epistemological elements of John Locke's moral philosophy as presented in the ‘Essay Concerning Human Understanding’ and ‘The Reasonableness of Christianity’. Many detractors hold that Locke's moral philosophy is internally inconsistent due to his seeming commitment to both the intellectualist position that divinely instituted morality admits of pure rational demonstration and the competing voluntarist claim that we must rely for our moral knowledge upon divine revelation. In this paper I argue that Locke is guilty of no such contradiction. In doing so, I attempt to accommodate Locke's position in the ‘Essay’ that moral principles are demonstrable a priori with his views on the sanctity of Christian revelation. I then consider Locke's conception of moral ideas as a species of mixed modes, or arbitrarily constructed complex ideas, and attempt to navigate the mechanism whereby human understanding can recognize these ideas as conforming to, or straying from, divinely appointed natural law. I conclude that despite Locke's failure to actually provide a full-fledged moral theory, he lays a rationally coherent groundwork for the fulfilment of such a project that accommodates a-priori rational reflection and divine revelation as complementary paths to moral understanding.     

SYMPOSIUM: LOCKE AND THE VEIL OF PERCEPTION Preface

Abstract: This Symposium comprises five papers on Locke's theory of sense perception. The authors are John Rogers, Gideon Yaffe, Lex Newman, Tom Lennon, and Martha Bolton. There are also comments on the papers, both individually and as a group, by Vere Chappell. In addition to Locke's view of perception, the papers deal with the nature of Lockean ideas and with the question whether Locke is committed to skepticism regarding the external world. The authors (and the commentator) disagree in their readings of Locke on these issues, but most maintain – and some argue – that he holds a representative theory of perception, and that he is not an external‐world skeptic.     

Hume,a Scottish Locke? Comments on Terence Penelhum's Hume

Where Terence Penelhum sees a deep continuity between John Locke's theory of ideas and David Hume's theory of perceptions, I argue that the two philosophers disagree over some fundamental issues in the philosophy of mind. While Locke treats ideas as imagistic objects that we recognize as such by a special kind of inner consciousness, Hume thinks that we do not normally recognize the imagistic content of our perceptions, and instead unselfconsciously take ourselves to sense a shared public world. My disagreement with Penelhum over Hume's debt to Locke helps to explain our disagreement over the nature of Hume's scepticism.     

Locke and the Primary Signification of Words: An Approach to Word Meaning

Locke's claim that the primary signification of (most) words is an idea, or complex of ideas, has received different interpretations. I support the majority view that Locke's notion of primary signification can be construed in terms of linguistic meaning. But this reading has been seen as making Locke's account vulnerable to various criticisms, of which I consider two. First, it appears to make the account vulnerable to the charge that an idea cannot play the role that a word meaning should play. I argue that the role Locke actually gives to signified ideas is not susceptible to this criticism. Second, it appears to make Locke guilty of at least some degree of semantic idealism. I argue that Locke is not guilty of this and that he makes a proper distinction between the non-referential relation that holds between a word and its primary signification and the referential relation that holds between a word and things the word is used to speak about.     

Lockean Empathy

This paper offers an epistemic defense of empathy, drawing on John Locke's theory of ideas. Locke held that ideas of shape, unlike ideas of color, had a distinctive value: resembling qualities in their objects. I argue that the same is true of empathy, as when someone is pained by someone's pain. This means that empathy has the same epistemic value or objectivity that Locke and other early modern philosophers assigned to veridical perceptions of shape. For this to hold, pain and pleasure must be a primary quality of the mind, just as shape is a primary quality of bodies. Though Locke did not make that claim, I argue that pain and pleasure satisfy his criteria for primary qualities. I consider several objections to the analogy between empathy and shape‐perception and show how Locke's theory has resources for answering them. In addition, the claim that empathetic ideas are object‐matching sidesteps Berkeley's influential objection to Locke's theory of resemblance. I conclude by briefly considering the prospects for a similar defense of empathy in contemporary terms.     

TWO KINDS OF INTENTIONALITY IN LOCKE

Ideas play at least two roles in Locke's theory of the understanding. They are constituents of ‘propositions,’ and some of them ‘represent’ the qualities and sorts of surrounding bodies. I argue that each role involves a distinct kind of intentional directedness. The same idea will in general be an ‘idea of’ two different objects, in different senses of the expression. Identifying Locke's scheme of twofold ‘ofness’ reveals a common structure to his accounts of simple ideas and complex ideas of substances. A consequence is a distinction among substance sorts parallel to one of his distinctions between primary and secondary qualities.     

Narrative,Expression and Mental Substance

This paper starts from the debate between proponents of a neo‐Lockean psychological continuity view of personal identity, and defenders of the idea that we are simple mental substances. Each party has valid criticisms of the other; the impasse in the debate is traced to the Lockean assumption that substance is only externally related to its attributes. This suggests the possibility that we could develop a better account of mental substance if we thought of it as having an internal relation to its states. I suggest that we may be able to do this by relying on the notion of expression. In developing this idea I draw heavily on aspects of Wittgenstein's philosophical psychology, while also developing and criticizing Strawson's account of persons and recent work by Lynne Baker. I conclude by arguing that mental substance, understood in this way, can only be grasped in narrative terms; substantialist and narrative accounts of personal identity, far from being opposed, are mutually supporting and require one another to be coherent.     

Lockean Essentialism and the Possibility of Miracles

If the laws of nature are metaphysically necessary, then it appears that miracles are metaphysically impossible. Yet Locke accepts both essentialism, which takes the laws to be metaphysically necessary, and the possibility of miracles. I argue that the apparent conflict here can be resolved if the laws are by themselves insufficient for guaranteeing the outcome of a particular event. This suggests that, on Locke's view, the laws of nature entail how an object would behave absent divine intervention . While other views of laws also make miracles counterfactually dependent on God's will, I show how this view is consistent with the essentialist commitment to the view that the laws are metaphysically necessary. Further, I argue that Locke's view is a relatively attractive version of essentialism, in part, because it allows for the possibility of miracles.     

LOCKE ON IDEAS OF SUBSTANCE AND THE VEIL OF PERCEPTION

Abstract: John Yolton has argued that Locke held a direct realist position according to which sensory ideas are not perceived intermediaries, as on the representational realist position, but acts that take material substances as objects. This paper argues that were Locke to accept the position Yolton attributes to him he could not at once account for appearance‐reality discrepancies and maintain one of his most important anti‐nativist arguments. The paper goes on to offer an interpretation of Locke's distinction between ideas of substances and modes, a distinction that helps Locke to explain appearance‐reality discrepancies, although not in a large enough range of cases to strengthen Yolton's interpretation.     

LIBERTY,NECESSITY AND CHANCE: HOBBES'S GENERAL THEORY OF EVENTS

Locke characterizes sensitive knowledge as knowledge of the existence of external objects present to the senses, and in terms of an ‘assurance’ that falls short of the certainty of intuition and demonstration. But it is unclear how this fits with his general definition of knowledge, as the perception of the agreement or disagreement of ideas, and it is unclear how that assurance can amount to knowledge, rather than amounting to mere probability (which he contrasts with knowledge). Some contend that Locke does not regard sensitive knowledge as genuine knowledge, but only honourifically calls it knowledge. In contrast, I argue that Locke holds that sensitive knowledge is knowledge, though he takes the conditions for it to be very different from the conditions for intuitive and demonstrative knowledge. It is not the assurance alone which Locke thinks qualifies sensitive knowledge as such: it is also the fact that the assurance arises from the actual employment of the senses upon external objects, and the fact that the senses do not generally deceive us, which he thinks qualifies sensitive knowledge as genuine knowledge. That there is a (tacit) form of externalism in Locke's account of sensitive knowledge is the main thesis of this paper.     

LOCKE ON SENSITIVE KNOWLEDGE AND THE VEIL OF PERCEPTION – FOUR MISCONCEPTIONS1

Abstract: Interpreters of Locke's Essay are divided over whether to attribute to him a Representational Theory of Perception (RTP). Those who object to an RTP interpretation cite (among other things) Locke's Book IV account of sensitive knowledge, contending that the account is incompatible with RTP. The aim of this paper is to rebut this kind of objection – to defend an RTP reading of the relevant Book IV passages. Specifically, I address four influential assumptions (about sensitive knowledge) cited by opponents of an RTP interpretation and argue that in each case the assumption is false.     

WHAT KIND OF PHILOSOPHER WAS LOCKE ON MIND AND BODY?

The wide range of conflicting interpretations that exist in regard to Locke's philosophy of mind and body (i.e. dualistic, materialist, idealistic) can be explained by the general failure of commentators to appreciate the full extent of his nominalism. Although his nominalism that focuses on specific natural kinds has been much discussed, his mind‐body nominalism remains largely neglected. This neglect, I shall argue, has given rise to the current diversity of interpretations. This paper offers a solution to this interpretative puzzle, and it attributes a view to Locke that I shall describe as nominal symmetry.     

Reflection,Nature, and Moral Law: The Extent of Catharine Cockburn's Lockeanism in her Defence of Mr. Locke's Essay

This essay examines Catharine Cockburn's moral philosophy as it is developed in her Defence of Mr. Locke's Essay on Human Understanding. In this work, Cockburn argues that Locke's epistemological principles provide a foundation for the knowledge of natural law. Sheridan suggests that Cockburn's objective in defending Locke's moral epistemology was conditioned by her own prior commitment to a significantly un‐Lockean theory of morality. In exploring Cockburn's views on morality in terms of their divergence from Locke's, the author hopes to underscore the extent of Cockburn's intellectual independence and her philosophical creativity.     

LOCKE AND THE OBJECTS OF PERCEPTION

Abstract: It is common to assume that if Locke is to be regarded as a consistant epistemologist he must be read as holding that either ideas are the objects of perception or that [physical] objects are. He must either be a direct realist or a representationalist. But perhaps, paradoxical as it at first sounds, there is no reason to suppose that he could not hold both to be true. We see physical objects and when we do so we have ideas. We see or hear birds and bells but we also have visual and auditory ideas of birds and bells. This suggestion is explored through examination of what Locke says about perception in his Elements of Natural Philosophy and the accounts offered both by Locke in the Essay Concerning Human Understanding and by some of Locke's successors.     

Locke on Individuation and the Corpuscular Basis of Kinds1

In this paper, I examine the crucial relationship between Locke’s theory of individuation and his theory of kinds. Locke holds that two material objects—e.g., a mass of matter and an oak tree—can be in the same place at the same time, provided that they are ‘of different kinds’. According to Locke, kinds are nominal essences, that is, general abstract ideas based on objective similarities between particular individuals. I argue that Locke’s view on coinciding material objects is incompatible with his view on kinds. In order for two material objects to be in the same place at the same time, they must differ with respect to at least one nominal essence. However, Locke thinks that it is impossible that x and y have the same real essence but differ with respect to any nominal essence; and coinciding material objects have the same real essence. Therefore, Locke cannot hold what he in fact holds, namely that distinct material objects can be in the same place at the same time.     

The Idea of Power and Locke's Taxonomy of Ideas

Locke's account of the idea of power is thought to be seriously problematic. Commentators allege (1) that the idea of power causes problems for Locke's taxonomy of ideas, (2) that it is defined circularly, and (3) that, contrary to Locke's claims, it cannot be acquired in experience. This paper defends Locke's account. Previous commentators have assumed that there is only one idea of power. But close attention to Locke's text, combined with background features of his theory of ideas, supports the drawing of a distinction between four different ideas of power. The paper describes each idea and its role in the Essay. It then argues that this distinction can help Locke to avoid the traditional criticisms.     

Locke,Arnauld, and abstract ideas

A great deal of the criticism directed at Locke’s theory of abstract ideas assumes that a Lockean abstract idea is a special kind of idea which by its very nature either represents many diverse particulars or represents separately things that cannot exist in separation. This interpretation of Locke has been challenged by scholars such as Kenneth Winkler and Michael Ayers who regard it as uncharitable in light of the obvious problems faced by this theory of abstraction. Winkler and Ayers argue that Locke instead held that to have an abstract idea is to attend selectively to some portion of the content of a particular idea. On this view, to have an abstract idea is not to have a special kind of idea but to have an ordinary idea in a special way. Ayers argues that Locke inherited this theory from Arnauld. I argue that the case made by Ayers for the attribution of the extrinsic theory to Locke rests on a misinterpretation of Arnauld. In fact, both Locke and Arnauld regard selective attention as part of a process whereby a new kind of idea is constructed.
