According to a common opinion, human olfactory experiences are significantly different from human visual experiences. For instance, olfaction seems to have only rudimentary abilities to represent space; it is not clear whether olfactory experiences have any mereological structure; and while vision presents the world in terms of objects, it is a matter of debate whether there are olfactory object-representations. This paper argues that despite these differences visual and olfactory experiences share a hierarchical subject/property structure. Within this structure, olfactorily experienced odours (...) and visual objects have the same status: they are primary subjects which unify other represented elements into perceptual units. (shrink)

The topic of this paper is the perception of properties. It is argued that the perception of properties allows for a distinction between the sense of the identity and the sense of the qualitative nature of a property. So, for example, we might perceive a property as being identical over time even though it is presented as more and more determinate. Thus, you might see an object first as red and then as crimson red. In this case, the property is (...) perceived as identical over time, even though the sense of the qualitative nature (the redness, the crimson redness) of the property is changing. The distinction between the sense of identity and the sense of quality is explicated in terms of perceiving a particular property, a trope, and perceiving it as an instance of a universal. It is subsequently argued that the perceived tropes cannot constitute the phenomenal character of the perceptual experience. (shrink)

The essence of an accident consists in its relationship to a substance. For we should not imagine that an accident is a thing in its own right to which gets attached a relationship or a link to a substance in which that accident exists. For if so, an accident would be something in its own right, dependent on substance only as extrinsic, and on this view, an accident could be cognized apart from the substance. These outcomes are impossible, however. Hence, (...) what an accident is to something of the substance: either a measure, or a state, and so on. Thus, the Philosopher says that an accident has being only because it belongs to something that has being. (shrink)

What are properties? Examples are easy. Consider a particular billiard ball. The ball is red, spherical, and has a definite mass. The ball's redness, sphericity, and mass are properties: properties of the ball. Putting it this way invites a distinction between the ball, a bearer of properties, and the ball's properties. Some philosophers deny that there are properties. To say that the ball is red or spherical, for instance, is just to say that the predicates "is red" and "is spherical" (...) apply truly to the ball. But it is hard not to think that "is red" applies truly to the ball, if it does, because the ball is a particular way, the red way; and "is spherical" applies to the ball because it is a particular way, the spherical way; and the ways in question are distinct ways the ball is. Ways the ball is are, or appear to be, properties of the ball. (shrink)

In this paper we advocate the thesis that qualia are tropes (or qualitons), and not (universal) properties. The main advantage of the thesis is that we can accept both the Wittgensteinian and Sellarsian assault on the given and the claim that only subjective and private states can do justice to the qualitative character of experience. We hint that if we take qualia to be tropes, we dissolve the problem of inverted qualia. We develop an account of sensory concept acquisition that (...) takes the presence of qualia as an enabling condition for learning. We argue that qualia taken to be qualitons are part of our mechanism of sensory concept acquisition. (shrink)

In the first part ("Determination"), I consider different notions of determination, contrast and compare modal with non-modal accounts and then defend two a-modality theses concerning essence and supervenience. I argue, first, that essence is a a-modal notion, i.e. not usefully analysed in terms of metaphysical modality, and then, contra Kit Fine, that essential properties can be exemplified contingently. I argue, second, that supervenience is also an a-modal notion, and that it should be analysed in terms of constitution relations between properties. (...) In the second part ("A Theory of Truthmaking"), I first review the literature on ontological commitment, and argue that the notion of truthmaking is better suited to play its explanatory rôle. I then argue that we should take truthmaker theory seriously, and that we should provide actual truthmakers for all truths there are. In the last chapter of this part, I review Armstrong's truthmaker theories and argue that they are unsatisfactory. I generalise my criticism to an argument against truthmaker necessitarianism, the view that truthmakers necessarily make true the truths they are truthmakers of. In the third part ("Properties and their Kind(s)"), I discuss qualitative determination. I present and endorse the truthmaker argument for universals, and defend universalism against friends of tropes, states of affairs and facts. I then give a novel characterisation of the important class of intrinsic properties, building on Lewis' work. With a workable notion of intrinsicness at hand, I argue that relations are ontologically – but not "ideologically" – dispensable: qualitative determination in general is a matter of intrinsic structure. In the future, I plan to add two parts and to publish my thesis as a book: In the fourth part ("Exemplification"), I argue for the existence of an exemplification relation tying universals and particulars together. I derive theoretical benefits from this relation by providing adverbialist theories of modality and tense and identify exemplification with a type of parthood. In the fifth part ("Qua qua qua"), I investigate the curious and interesting ontological category of so-called "qua-objects" (Picasso-as-a-painter, for example) and argue that they exist, are not identical with transworld indidivuals or modal parts and that they provide (contingent) truthmakers for all true predications.

ABSTRACTThe paper takes up a conception of substances according to which substances are simple property bearers, properties being modes, particular qualitative ways individual substances are. What a substance does or would do is determined by its qualities. Efficient causation is to be understood as the manifesting of powers possessed by substances owing to their qualitative natures. Although complexes, entities with substantial parts, are not substances, they would be no less real, no less participants in the causal fray. What the substances (...) and properties are is an empirical matter, however, to be settled, if at all, by physics. For all we know, the substances might be particles, or fields, or the universe as a whole. Efficient causation appears to require pluralism: distinct interacting substances. In a non-pluralistic universe, causal truths would be relegated to the manifest image: true still, but made true by non-causal features of the universe perhaps revealed by the scientific image. There remains the final reflection, how shallow, puny, and imperfect are efforts to sound the depths in the nature of things. In philosophical discussion, the merest hint of dogmatic certainty as to finality of statement is an exhibition of folly. : x). (shrink)

The traditional ontology within which chemistry has developed involved various versions of a general substance/attribute scheme. Recently this has been challenged by two versions of Dynamism. One version is derived from the writings of A. N. Whitehead and the other from several sources, including G. Leibniz and I. Kant. Both involve the idea of flux of actual occasions. Unlike the former scheme, the latter involves a foundation of causal powers and the energetics of field theory. The situation has been made (...) more interesting because of the revival of trope theory, based on an ontology of particularized attributes. This notion is claimed to resolve philosophical problems about the nature of universals and of substances through the introduction of spatial and temporal sequences of tropes. While trope theory seems, at first sight, to work as an attractive alternative to substance/attribute close inspection shows that it is beset with difficulties that are more problematic that the dynamist ontology based on casual powers, dispositions and affordances.

In this paper I attempt to show, against certain versions of trope theory, that properties with analyzable particularity cannot be merely exactly similar: such properties are either particularized properties (tropes) that are dissimilar to every any other trope, or else universalized properties (universals). I argue that each of the most viable standard and nonstandard particularizers that can be employed to secure the numerical difference between exactly similar properties can only succeed in grounding the particularity of properties, that is, in having (...) properties be tropes, at the expense of ruling out the possibility of their exact similarity. Here are the four nonstandard particularizers that I examine: the genealogy of a property, the history of a property, the causal effects of a property, and the duration of a property. And here are the two standard particularizers that I examine: the bearer of a property, by which I mean either a bare particular or a spatiotemporal location, and the property itself, by which I mean that the property is self-particularized. In my concluding remarks, I explain that the only remaining hope for preserving the possibility of exactly similar tropes is regarding properties as primitively particular, and that this must mean not that properties are selfparticularized but that they are particularized due to nothing. I close by arguing that this may not help trope theory after all. (shrink)
