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.     

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's Reply to the Skeptic

Given his representationalism how can Locke claim we have sensitive knowledge of the external world? We can see the skeptic as asking two different questions: how we can know the existence of external things, or more specifically how we can know inferentially of the existence of external things. Locke's account of sensitive knowledge, a form of non‐inferential knowledge, answers the first question. All we can achieve by inference is highly probable judgment. Because Locke's theory of knowledge includes both first order psychological and second order normative conditions, sensitive knowledge can be non‐inferential and less certain than intuitive and demonstrative knowledge.     

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 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.     

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.     

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.     

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.     

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.     

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.     

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.     

THE BIBLICAL ROOTS OF LOCKE'S THEORY OF PERSONAL IDENTITY

Locke's consciousness‐based theory of personal identity resulted not only from his agnosticism on substance, but also from his biblical theology. This theory was intended to complement and sustain Locke's moral and theological commitments to a system of otherworldly rewards and sanctions as revealed in Scripture. Moreover, he inferred mortalist ideas from the Bible, rejecting the resurrection of the same body and maintaining that the soul dies at physical death and will be resurrected by divine miracle. Accordingly, personal identity is neither in the soul, nor in the body, nor in a union of soul and body. To Locke, personal identity is in consciousness, which, extending “backwards to any past Action or Thought,” enables the self, both in this life and upon resurrection for the Last Judgment, to recognize that “it is the same self now it was then; and ‘tis by the same self with this present one that now reflects on it, that that Action was done” (Essay II.xxvii.9).     

LOCKE ON THE SEMANTIC AND EPISTEMIC ROLE OF SIMPLE IDEAS OF SENSATION

Abstract: This paper argues that Locke has a representative theory of sensitive knowledge. Perceivers are immediately aware of nothing but sensory ideas in the mind; yet perceivers think of real external substances that correspond to and cause those ideas, and they are warranted in believing that those substances exist (at that time). The theory poses two questions: what warrants the truth of such beliefs? What is it in virtue of which sensory ideas represent external objects and how do they make perceivers think of those objects? Both the epistemic and semantic issues need to be addressed. This paper urges that Locke's basic account of warrant is roughly reliabilist. The causal origin of sensory ideas assures that, in general, sense based beliefs are true. Locke defines the limit of this warrant by the theoretical point that we cannot discuss skeptical doubt without assuming the truthfulness of our perceptual faculty. Turning to the semantic question, the paper argues that ideas are mental modifications or entities. They are not intrinsically representative (satisfiable), but rather represent only by virtue of their causal origin. They merely “track” the presence of substances and their qualities. Ideas nevertheless prompt perceivers to think of their causes. This is roughly because sensory ideas have a specific mental role, namely, to serve as marks for distinguishing substances and their respective qualities for purposes of action. The paper suggests that, for Locke, the challenge posed by the semantic veil of ideas is to explain this externally directed marking function within bounds of his anti‐innatism. But it concludes that his answers to the twin questions fit together reasonably well.     

THE LOGIC OF IDEAS AND THE LOGIC OF THINGS: A REPLY TO CHAPPELL

Abstract: A continuation of the debate over the intelligibility, and plausibility, of Yolton's reading of Locke's account of perception. Here, the issue turns on the de‐reification of ideas and its implications for the putative axioms of symmetry and transitivity governing the identity of ideas. The issue is illustrated by what Locke says about confused ideas.     

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.     

Can You Do It? How Preschoolers Judge Whether Others Have Learned

Two experiments investigated how preschoolers judge whether learning has occurred. Experiment 1 showed that 3- and 4-year-olds used an individual's ability to demonstrate knowledge to judge whether he/she had learned something, regardless of that individual's claim about whether he/she had learned. Experiment 2 considered whether children responded based on just the character's demonstrative ability or whether children integrate various pieces of mental state knowledge to make a judgment about learning. Using a similar procedure, preschoolers were first told that the character claimed to be ignorant and then that they learned or did not learn a piece of information. In these cases, judgments of learning changed when the characters' claims and demonstrative abilities conflicted. These results suggest that children's understanding of learning involves the integration of various pieces of mental state knowledge. This process starts in the preschool years, but these data also suggest that crucial developments are taking place after age 4.     

Hume on the social construction of mathematical knowledge

Mathematics for Hume is the exemplary field of demonstrative knowledge. Ideally, this knowledge is a priori as it arises only from the comparison of ideas without any further empirical input; it is certain because demonstration consist of steps that are intuitively evident and infallible; and it is also necessary because the possibility of its falsity is inconceivable as it would imply a contradiction. But this is only the ideal, because demonstrative sciences are human enterprises and as such they are just as fallible as their human practitioners. According to the reading suggested here, Hume develops a radical sceptical challenge for mathematics, and thereby he undermines the knowledge claims associated with demonstrative reasoning. But Hume does not stop there: he also offers resources for a sceptical solution to this challenge, one that appeals crucially to social practices, and sketches the social genealogy of a community-wide mathematical certainty. While explaining this process, he relies on the conceptual resources of his faculty psychology that helps him to distinguish between the metaphysics and practices of mathematical knowledge. His account explains why we have reasons to be dubious about our reasoning capacities, and also how human nature and sociability offers some remedy from these epistemic adversities.
