The question whether qualities are metaphysically more fundamental than or mere limiting cases of relations can be addressed in an applied symbolic logic. There exists a logical equivalence between qualitative and relational predications, in which qualities are represented as one-argument-place property predicates, and relations as more-than-one-argument-place predicates. An interpretation is first considered, according to which the logical equivalence of qualitative and relational predications logically permits us ontically to eliminate qualities in favor of relations, or relations in favor of qualities. If metaphysics is understood at least in part as an exercise in ontic economy, then we may be encouraged to adopt a property ontology of qualities without quality-irreducible relations, or relations without relation-irreducible qualities. If either strategy is followed, the choice of reducing qualities to relations or relations to qualities will need to be justified on extra-logical grounds. These might include a perceived greater intuitiveness, explanatory fecundity, compatibility with cognitive ontogeny or developmental psychology, expressive or explanatory elegance or cumbersomeness, and an open-ended list of philosophical motivations that could reasonably favor the ontic prioritization of qualities over relations or relations over qualities. Despite its intuitive appeal, the thesis that logical equivalence together with extra-logical preferences justifies unidirectional ontic reduction of relations to qualities or qualities to relations is rejected in light of the more defensible proposition that the logical equivalence of qualitative and relational predications actually supports the opposite conclusion, that both qualities and relations are logically indispensable to a complete ontology of properties. The logical equivalence of qualitative and relational predications, insofar as we continue to observe the distinction, makes it logically necessary ontically for both qualities and relations to exist whenever either one exists. That logically equivalent qualitative and relational predications have as their truth-makers the exemplification by objects of both qualities and relations as equi-foundational properties further suggests that there is no deeper logical distinction between qualities and relations, but only two convenient lexical-grammatical designations for property predications involving one- versus more-than-one-argument-place.

Roger Scruton appears to have been the first to argue for and articulate an anti-realist theory of aesthetic properties. In the case of emotional qualities of music, his principal argument against realism is unsound and cannot, I believe, be repaired. Nevertheless an anti-realist view of emotional qualities of music is in my view correct and I defend Scruton's insight against a rival realist conception. However, I prefer a rather different form of anti-realism to Scruton's.

What is the relationship between sounds and time? More specifically, is there something essentially or distinctively temporal about sounds that distinguishes them from, say, colors, shapes, odors, tastes, or other sensible qualities? And just what might this distinctive relation to time consist in? Apart from their independent interest, these issues have a number of important philosophical repercussions. First, if sounds are temporal in a way that other sensible qualities are not, then this would mean that standard lists of paradigm secondary qualities offered by Locke, Galileo, and other modern philosophers — lists which include colors, odors and sounds without any significant distinctions — overlook significant metaphysical differences. This, in turn, would threaten to undermine the coherence of the modern understanding of secondary qualities itself. Moreover, a number of authors have recently urged that the essential temporality of sounds makes it impossible to understand sounds as properties (except on a trope theory of properties; see note 3). If true, and given the more or less universal view that colors are properties, this last conclusion would make potentially inapplicable to sounds much of the comparatively well-developed philosophical taxonomy and apparatus that has arisen in philosophical disputes over the status of colors (for presentations of this taxonomy and apparatus see, for example, Byrne and Hilbert (2003); Cohen (2008b)).1 Therefore, the conclusion that sounds are distinctively temporal would be a serious blow to hopes for a theoretically unified treatment of the sensory qualities.2 For all these reasons, quite a lot seems to hang on the question of the temporality of sounds.

Given Locke’s views on primary and secondary qualities, it seems he is committed to there being real underlying properties in objects, the arrangement and disposition of which underlies and produces the observed properties of that object. It might be natural to think that these primary qualities provide a general system for classifying objects into classes: that we could delineate the real kinds of objects in nature by looking at what their real primary qualities were. A list of the particular qualities of some object would define that object perfectly precisely; by looking at which properties were shared or divergent between this object and others, we group the object with others in the same kind. These real kinds in nature can play several important theoretical roles. They can support real scientific understanding, including inductive inferences (iof things are of the same real kind, then observed properties of one support the inference to unobserved properties of the other); they can form the basis for our judgements about the powers and capacities of particular objects, based on the what other things of that type can do; and these real kinds can provide the meanings for general terms: the thought being that the meanings of class names are empty without real classes to which they correspond.

Peter Hare published two books about philosophy, both co-authored with his colleague Edward Madden. The first was Evil and the Problem of God, while the second was titled Causing, Perceiving and Believing: An Examination of the Philosophy of C. J. Ducasse (Dordrecht, Holland: D. Reidel), published in 97 . Hare's choice of Ducasse for extended study tells us a great deal about Hare's own interests. Ducasse was a confessedly analytic philosopher who advocated several views extending classical American themes. From metaphysics and epistemology to ethics and aesthetics, Ducasse struck Hare as a philosopher worthy of promotion and preservation.Hare and Madden had an interest in Ducasse for some years.1 However, there ..

In theorizing about perception, philosophers have often multiplied qualities. To perceptible qualities of external objects, like colors and shapes (‘sensible’ qualities), have been added qualities of experiences (‘sensory’ qualities) or of sense-data (‘sensational’ qualities). Start with sensory qualities. The phrase ‘sensory quality’ is not much in use these days, having lost out to ‘phenomenal character,’ ‘phenomenal property,’ ‘qualitative character,’ or ‘quale.’ But whatever sensory qualities are called, pinning them down is no easy matter.

QUESTIONS Objects seem to have some properties in themselves (like shape), and some other properties that depend on other things around them (like being alone or accompanied). The distinction between primary and secondary qualities is a special case of this more general contrast: what, according to Locke, is the basis for the distinction? Is there more than one way to understand Locke’s argument: what is the best reading of Locke? What wider significance does the distinction between primary and secondary qualities have?

The Dangerous Book for Boys Abstract: Seventeenth and eighteenth century discussions of the senses are often thought to contain a profound truth: some perceptible properties are secondary qualities, dispositions to produce certain sorts of experiences in perceivers. In particular, colors are secondary qualities: for example, an object is green iff it is disposed to look green to standard perceivers in standard conditions. After rebutting Boghossian and Velleman’s argument that a certain kind of secondary quality theory is viciously circular, we discuss three main lines of argument for the secondary quality theory. The first is inspired by an intuitively compelling picture of perception articulated by Reid; the second is that the secondary quality theory is a conceptual truth; the third line of argument is presented in Johnston’s influential paper ‘How to speak of the colors’. We conclude that all these arguments fail, and that the secondary quality theory is unmotivated. Keywords: color, secondary quality, disposition, vision, perception..
