HUME ON PRIMARY AND SECONDARY QUALITIES Hume's view of the primary/secondary quality distinction is, I believe, a matter of considerable interest. It bears upon Hume's position in relation to Locke and Berkeley, and has important implications for general features of his epistemology and metaphysics. The central part of my discussion will therefore be taken up with a consideration of those passages from his writings in which Hume refers (...) to the primary/ secondary quality distinction. Hume's treatment of this aspect of the 'modern philosophy' may be seen against the background of his discussion of perception and its objects, and it is therefore this with which I begin. HUME'S SYSTEM I refer to Hume's system in relation to perception and the manner in which objects affect the senses. Hume's avowed purpose here is to discuss the way in which objects appear to the senses (in particular, those of sight and touch), rather than to account for their real nature and operations. Our ignorance of the nature of bodies reflects the fact that we are limited in experience to those properties of objects which discover themselves 2 to the senses. In determining the nature of Hume's system there are, I think, two (related) factors to be taken into account: (i) Hume's distinction between perceptions and objects; and (ii) Hume's critique of the Naive or Direct Realist theory of perception. (i) Perceptions and Objects The distinction which Hume wishes to make between perceptions and objects, and his general account of the relation between them, is embodied in his 126. discussion of the idea of external existence (T 6). We may observe, that 'tis universally allow'd by philosophers, and is besides pretty obvious of itself, that nothing is ever really present with the mind but its perceptions or impressions and· ideas, and that external objects become known to us only by the perceptions they 3 occasion. We should note that what Hume is describing here is, in essence, the Indirect Realist account of perception, i.e. that we are acquainted with an external reality only in the form of perceptions ('impressions') which arise from sensory contact with it. That Hume is prepared to speak elsewhere of per4 ceptions in their relation to external objects as images is indicative of his commitment to a Representative theory. There are, of course, severe limitations upon our understanding of the relation between perceptions and objects. As every idea is deriv'd from a preceding perception, 'tis impossible our idea of a perception, and that of an object or external existence can ever represent what are specifically different from each other. In so far as external objects are supposed to differ from perceptions in their specific identity, we can form only a relative idea of them (T 68). Nevertheless the idea of bodies or objects is clearly to be distinguished from that of perceptions; while being specifically the same, like ideas and impressions, these items, or rather the ideas involved, are attended with the supposition of a difference, that is unknown and incomprehensible (T 244). As different existences perceptions and objects may be conceived to differ in respect of their relational properties, for example, but otherwise whatever is true of the one must also be true of the other. These two sets of distinctions — between, on the one hand, ideas and impressions and, on the other, perceptions and objects — may usefully be compared and 127. contrasted. In each case the items with which we are concerned are numerically different but specifically identical; and, furthermore, the relation between the items which make up each pair is a causal one. The obvious difference between the two cases is that while both impressions and ideas are objects of experience, the causal dependence of the one upon the other being revealed by the order of their appearance before the mind, we do not directly experience external objects as opposed to perceptions. Questions concerning the 'real nature' of objects or bodies belong to the province of natural - rather than 'moral' - philosophy, which indeed has reasonable hypotheses to offer (T 48). As for our idea of body, this comprises nothing more than the ideas... (shrink)

In lieu of an abstract, here is a brief excerpt of the content:61 PROJECTIONISM, REALISM, AND HUME'S MORAL SENSE THEORY* Introduction The character of Hume's moral theory is currently a topic of considerable discussion.1 We find in the recent literature essentially two sorts of interpretation of Hume's theory. On the one side there is the view that, for Hume, the distinction between virtue and vice is reducible to the moral sentiments of approval and disapproval. Associated with this view is the (...) further claim that Hume ascribes to us the belief that virtue and vice exist as the counterparts to these sentiments; and, in addition, that this belief is, for Hume, a mistaken one. For reasons which will become obvious this may be described as the Projectionist account of Hume. On the other side, there is the attempt to represent Hume's moral theory as a form of realism, i.e., a theory according to which there are moral properties belonging to actions, or the agents who perform them, which provide objective correlates of the feelings which those actions, or the agents concerned, induce in us as spectators. Now clearly an important part of what is at stake between these different interpretations is the question of how seriously we should take Hume's own description of this theory as one according to which moral distinctions are derived from a moral sense. It is characteristic of the Projectionist interpretation to suggest that 'sense' is equivalent here to 'sentiment', and, indeed, that Hume's moral sense theory is tantamount to the denial that there is anything in Objects' themselves corresponding to our moral (or aesthetic) sentiments. The Realist interpretation, on the other hand, stresses the importance of Hume's references in 62 the Treatise to a moral (and aesthetic) sense, and the precedent provided in this respect by Hutcheson; and it takes seriously the idea that this sense enables us to become acquainted, via the sentiments involved, with the qualities of virtue and vice. My own interest in these different interpretations concerns their disagreement about the way in which we should understand Hume's notion of a moral sense. I wish to argue against the Projectionist interpretation, and its dismissive treatment of Hume's references to a moral sense, though it is a further question whether the view of Hume which emerges deserves the name of 'Realism'. 1. The Projectionist Interpretation It seems clear that the notion of a moral sense cannot be intended literally, i.e., as though there is a form of moral sense-perception strictly comparable to the modes of perception provided by the external senses. It is, presumably, part of the definition of a sense that it is a faculty whose function depends upon stimulation of an organ or, at least, receptors peculiar to that sense; and, furthermore, in the case of the various external senses there is -- except for the contact sense of touch -- a distinctive medium of perception. For both these reasons moral sense theorists can only be proposing an analogy with the external senses. In Hume's case in particular, however, there appear to be reasons for doubting whether the analogy can be more than superficial. Perhaps the most obvious of these lies with Hume's insistence on the action-guiding character of the distinction between moral good and evil (see e.g., T 437-462). For it seems clear that sense-perceptions g as such can have no direct influence upon our actions. 63 Then there is Hume's denial that morality consists in any matter of fact (T 468; EPM 292). If virtue and vice are to be considered the objects of some form of moral sense-perception their existence presumably does become a matter of fact. Finally, a moral sense theory seems to imply that judgements of virtue and vice are straightforwardly true or false, according to whether or not we perceive veridical Iy; while Hume's own discussion sometimes points to a non-propositional view of moral utterances as the expression of certain feelings or sentiments. These last two points remind us that Hume often appears to deny that values belong as intrinsic properties to the objects evaluated. This is obviously true of the following, much quoted, passage: Take any... (shrink)

It is possible to distinguish a number of philosophical threads which run throughout Harris’s discussion of the philosophers with whom he is concerned. The following are perhaps the most significant.
