DH Mellor has argued that there can be no negative, disjunctive, or conjunctive properties. This argument has been criticized by Alex Oliver on the grounds that it rests on a contentious identity criterion for facts, but it seems to me that a simpler criticism is available. According to this criticism, the problem with Mellor's argument is that it trades on an ambiguity in the semantics of the phrase "the fact that", according to which "the fact that" can be understood as (...) creating either an intensional or an extensional context.

In this important study D. M. Armstrong offers a comprehensive system of analytical metaphysics that synthesises but also develops his thinking over the last twenty years. Armstrong's analysis, which acknowledges the 'logical atomism' of Russell and Wittgenstein, makes facts the fundamental constituents of the world, examining properties, relations, numbers, classes, possibility and necessity, dispositions, causes and laws. All these, it is argued, find their place and can be understood inside a scheme of states of affairs. This is a comprehensive and (...) rigorously this-worldly account of the most general features of reality, argued from a distinctive philosophical perspective, and it will appeal to a wide readership in analytical philosophy.

PURPOSE—A substantial fraction of the observations made by clinicians and entered into patient records are expressed by means of negation or by using terms which contain negative qualifiers (as in “absence of pulse” or “surgical procedure not performed”). This seems at first sight to present problems for ontologies, terminologies and data repositories that adhere to a realist view and thus reject any reference to putative non-existing entities. Basic Formal Ontology (BFO) and Referent Tracking (RT) are examples of such paradigms. The (...) purpose of the research here described was to test a proposal to capture negative findings in electronic health record systems based on BFO and RT. METHODS—We analysed a series of negative findings encountered in 748 sentences taken from 41 patient charts. We classified the phenomena described in terms of the various top-level categories and relations defined in BFO, taking into account the role of negation in the corresponding descriptions. We also studied terms from SNOMED-CT containing one or other form of negation. We then explored ways to represent the described phenomena by means of the types of representational units available to realist ontologies such as BFO. RESULTS—We introduced a new family of ‘lacks’ relations into the OBO Relation Ontology. The relation lacks_part, for example, defined in terms of the positive relation part_of, holds between a particular p and a universal U when p has no instance of U as part. Since p and U both exist, assertions involving ‘lacks_part’ and its cognates meet the requirements of positivity. CONCLUSION—By expanding the OBO Relation Ontology, we were able to accommodate nearly all occurrences of negative findings in the sample studied. (shrink)

Trope theory is the view that the world is a world of abstract particular qualities. But if all there is are tropes, how do we account for the truth of propositions ostensibly made true by some concrete particular? A common answer is that concrete particulars are nothing but tropes in compresence. This answer seems vulnerable to an argument (first presented by F. H. Bradley) according to which any attempt to account for the nature of relations will end up either in (...) contradiction, nonsense, or will lead to a vicious infinite regress. I investigate Bradley’s argument and claim that it fails to prove what it sets out to. It fails, I argue, because it does not take all the different ways in which relation and relata may depend on one another into account. If relations are entities that are distinct from yet essentially dependent upon their relata, the Bradleyan problem is solved. We are then free to say that tropes in compresence are what make true propositions ostensibly made true by concrete particulars. (shrink)

I examine and discuss in this paper Orilia’s theory of external, non-symmetrical relations, that is based on ontological roles (O-Roles). I explore several attempts to interpret O-Roles from an ontological viewpoint and I reject them because of two problems concerning the status of asymmetrical relations (to be distinguished from non-symmetrical relations simpliciter) and of exemplification as an external, non-symmetrical relation. Finally, following Heil’s and Lowe’s characterization of modes as particular properties that ontologically depend on their “bearers”, I introduce relational modes (...) in order to define a new solution to the problems of the ontological status of both external, non-symmetrical relations and O-Roles. I also deal with five objections raised by Fraser MacBride against relational modes and O-Roles and I elaborate an analysis of the relations of being to the left of and being to the right of.

Few philosophers believe in the existence of so-called negative properties. Indeed, many find it mind-boggling just to imagine such properties. In contrast, I think not only that negative properties are quite imaginable, but also that there are good reasons for believing that some such properties actually exist. In this paper, I want to defend the reality and irreducibility, or genuineness, as I call it, of negative properties. After briefly presenting the idea of a negative property, I collect commonly invoked tests (...) for the realness of things and attend to the question whether negative properties pass any of these. Next, I try to segregate the many different notions of irreducibility, probing whether negative properties can be reckoned to be genuine in any sense of the word. In the final section, I rebut some frequent objections raised against negative properties. _German_ Wenige Philosophen glauben an die Existenz sogenannter negativer Eigenschaften. Die meisten halten solche Eigenschaften sogar für unvorstellbar. Ich dagegen halte negative Eigenschaften nicht nur für denkbar, sondern glaube darüber hinaus, dass solche Eigenschaften tatsächlich existieren. In diesem Aufsatz möchte ich die Wirklichkeit und Irreduzibilität – oder Echtheit – negativer Eigenschaften verteidigen. Nachdem ich kurz die Idee einer negativen Eigenschaft vorstelle, ziehe ich geläufige Kriterien für die Realität von Dingen heran und überprüfe, ob negative Eigenschaften diese erfüllen. Als nächstes unterscheide ich verschiedene Begriffe von Irreduzibilität, um zu überprüfen, ob negative Eigenschaften als echt in irgendeinem Sinn des Wortes betrachtet werden können. Im letzten Abschnitt möchte ich einige häufige Einwände gegen negative Eigenschaften zurückweisen. (shrink)

Argle. I’ve said it before and I’ll say it again: all things are material. Either holes are somehow material, or else there are no such things. Maybe a hole is the material hole-lining that, as we so misleadingly say, “surrounds” the hole; or else whatever ostensible reference we make to holes is secretly some other sort of language-game altogether, or it’s fictitious reference, or it’s just plain mistaken.

When there is truth, there must be some thing (or things) to account for that truth: some thing(s) that couldn’t exist and the true proposition fail to be true. That is the truthmaker principle. True propositions are made true by entities in the mind-independently existing external world. The truthmaker principle seems attractive to many metaphysicians, but many have wanted to weaken it and accept not that every true proposition has a truthmaker but only that some important class of propositions require (...) truthmakers.1 Let us, following Armstrong, call the claim that all true propositions, without exception, have a truthmaker, Truthmaker Maximalism. Why might one be tempted to the spirit of truthmaker theory but reject Truthmaker Maximalism? Well, you might deny that necessary truths need truthmakers, for one, and insist that only contingent truths have truthmakers. But I think it’s fair to say that the most common motivation for rejecting maximalism concerns negative truths. The thought that negative truths are exempt from the demand for truthmakers could be justified in one of two ways: there is the claim that we don’t need truthmakers for negative truths, and there is the claim that we can’t have..

The metaphysics of relations is still in its infancy. We use the idea of truthmaking to gain purchase on this metaphysics. Assuming a modest supervenience conception of truthmaking, where true relational predications require multiply dependent truthmakers, these are indispensable relations. Though some such relations are required, none are needed for internal relatedness, nor for several other kinds of relational predication. Discerning the metaphysically basic kinds of relations is fraught with uncertainties, but must be tackled if progress is to be made.

Given the centrality of arguments from vicious infinite regress to our philosophical reasoning, it is little wonder that they should also appear on the catalogue of arguments offered in defense of theses that pertain to the fundamental structure of reality. In particular, the metaphysical foundationalist will argue that, on pain of vicious infinite regress, there must be something fundamental. But why think that infinite regresses of grounds are vicious? I explore existing proposed accounts of viciousness cast in terms of contradictions, (...) dependence, failed reductive theories and parsimony. I argue that no one of these accounts adequately captures the conditions under which an infinite regress—any infinite regress—is vicious as opposed to benign. In their place, I suggest an account of viciousness in terms of explanatory failure. If this account is correct, infinite grounding regresses are not necessarily vicious; and we must be much more careful employing such arguments to the conclusion that there has to be something fundamental.

Despite heroic efforts, philosophers have found it increasingly difficult to evade discussion of metaphysical topics. Take the philosophy of mind. Take, in particular, the mind-body problem in its latest guise: the problem of causal relevance. If mental properties are not reducible to physical properties, how can we reconcile the role such properties seem to have in producing bodily motions that constitute actions with the apparent fact that the very same motions are entirely explicable on the basis of purely physical properties (...) of purely physical events in the nervous system? Familiar approaches to the problem include appeals to “supervenient causation,” to “higher-level” laws governing putatively higher-level entities and events, and to “realizing” relations that make room in objects for overlapping properties.

I argue that the one and only truthmaker is the world. This view can be seen as arisingfrom (i) the view that truthmaking is a relation of grounding holding between true propositions and fundamental entities, together with (ii) the view that the world is the one and only fundamental entity. I argue that this view provides an elegant and economical account of the truthmakers, while solving the problem of negative existentials, in a way that proves ontologically revealing.

The author argues for the existence of negative facts. The first section is devoted to an argument, grounded on truthmaker maximalism, that aims at demonstrating that negative facts must exist at least as false propositions’ falsemakers. In the second section, the author analyzes and criticizes several attempts to get rid of negative facts: the ones based on incompatibilities, absences, totality facts and polarities, as well as the ones based on various restrictions on truthmaker maximalism or on the non-acceptance of facts (...) as truthmakers. In particular, it is shown that an ontology that accepts negative facts is simpler than an ontology that denies their existence and that in general, many attempts to get rid of negative facts turn out to recognize the existence of such entities or of entities that are more mysterious than negative facts themselves.

This paper seeks to differentiate negative properties from positive properties, with the aim of providing the groundwork for further discussion about whether there is anything that corresponds to either of these notions. We differentiate negative and positive properties in terms of their functional role, before drawing out the metaphysical implications of proceeding in this fashion. We show that if the difference between negative and positive properties tabled here is correct, then negative properties are metaphysically contentious entities, entities that many philosophers (...) will be unwilling to countenance.
