Universals

This paper raises a problem for the pair of views that universals are immanent in their instantiations and that these instantiations, or states of affairs, are somehow constructed from the instantiated universals. It is argued that the pair is inconsistent. The first view implies that universals are prior to states of affairs, whereas the second view implies that states of affairs are prior to universals. This paper does not attempt to solve this problem, but rather to formulate it precisely. That (...) promises to illuminate how to solve the problem if it can be solved, or why it cannot be solved if it is unsolvable. (shrink)

This paper responds to the contributions by Alexander Bird, Nathan Wildman, David Yates, Jennifer McKitrick, Giacomo Giannini & Matthew Tugby, and Jennifer Wang. I react to their comments on my 2015 book Potentiality: From Dispositions to Modality, and in doing so expands on some of the arguments and ideas of the book.

The problem of universals remains a philosophical theme not only in ontology but also in epistemology. In Husserl, there are particular universals, the noematic ‘X’, the identical, and universals stricto sensu, atemporal universal names. In this paper, I present the theme as it is analyzed by Husserl in Ideas I. In the first section, I describe the trajectory to the universals highlighting the parallelism between noese and noema. In the second section, I draw the reflection of this problem on the (...) philosophy of language which is also affected by the noeticnoematic correspondence. In the third and last section, I show how the investigation about the universals moves in the noematic sphere, and conclude defending the possibility of reaching the universal strict sense departing from the noematic ‘X’.

A Platonic explanation of non-modal and modal truths is explained and defended using non-spatiotemporal entities as their truthmakers. It is argued, further, that this theory is parsimonious, naturalistic, and ontologically serious. These features should commend the view to a wide swath of philosophers.

Prince of Networks is the rst treatment of Bruno Latour speci cally as a philosopher. Part One covers four key works that display Latour’s underrated contributions to metaphysics: Irreductions, Science in Action, We Have Never Been Modern, and Pandora’s Hope. Harman contends that Latour is one of the central gures of contemporary philosophy, with a highly original ontology centred in four key concepts: actants, irreduction, translation, and alliance.

Presupposing that most predicates do not correspond directly to genuine relations, I argue that all genuine relations are symmetric. My main argument depends on the premise that there are no brute necessities, interpreted so as to require logical and metaphysical necessity to coincide for sentences composed entirely of logical vocabulary and primitive predicates. Given this premise, any set of purportedly primitive predicates by which one might hope to express the facts about non-symmetric relations order their relata will generate an objectionable (...) multiplication of possibilities. In the final section I give a different argument, based on the weaker premise that brute necessities should not be multiplied without necessity. (shrink)

Are concrete objects in some sense made up of the properties they exemplify? A distinguished tradition holds they are. I begin by defending the distinction: there is a real and not just semantic distinction between asserting and denying that concrete objects have their properties as parts. I then argue in favor of the view that concrete objects are not made up of their parts. First, this view has less ontological baggage than its opponent. Next, the supposed advantages of the alternative (...) view—its superiority in understanding persistence, exemplification, or the possibility of diverse duplicates—dissipate under analysis. (shrink)

I present in this article a new theory of structural properties or, more precisely, of structural kinds, such as being methane. According to this theory, structural kinds are kinds that are both emergent and sustained in their existence. In the first section, I introduce structural properties and four problems that affect the most widely held conception of them, namely, the pictorial conception. In the second section, I introduce some theses about emergence, powers, emergent powers, relations and structures that I have (...) defended in other works and that constitute the basis on which my theory of structural kinds is built up. In the third section, I eventually develop my theory in full detail and show how it can solve the problems mentioned in the second section. Finally, in the fourth section, I face five objections and briefly compare my account with some other accounts of structural properties. (shrink)

The possibility of multilocation --- of one entity having more than one exact location --- is required by several metaphysical theories such as the immanentist theory of universals and three-dimensionalism about persistence. One of the most pressing challenges for multi-location theorists is that of making sense of exact location --- in that extant definitions of exact location entail a principle called Functionality, according to which nothing can have more than one exact location. Recently in a number of promising papers, Antony (...) Eagle has proposed and defended a definition of exact location in terms of weak location that does not entail Functionality. This paper provides the first thorough assessment of Eagle’s proposal. In particular, we argue that it cannot account for (i) location of immanent universals, (ii) multi-location of mereologically changing three-dimensional objects , (iii) multi-location of mereologically complex objects, and (iv) mereologically simple but extended objects.

Trope theory is a leading metaphysical theory in analytic ontology. One of its classic statements is found in the work of Donald C. Williams who argued that tropes qua abstract particulars are the very alphabet of being. The concept of an abstract particular has been repeatedly attacked in the literature. Opponents and proponents of trope theory alike have levelled their criticisms at the abstractness of tropes and the associated act of abstraction. In this paper I defend the concept of a (...) trope qua abstract particular by rejecting arguments that purport to show that tropes should not be understood as abstract and by arguing that the abstractness of tropes plays an indispensable role in one of our more promising trope-theoretic analyses of universals and of concrete objects.

I put in question in this article the existence of conjunctive properties. In the second section, after having provided a characterization of conjunctive properties, I develop an argument based on the principle of ontological parsimony: if we accept that there are conjunctive properties in the universe then, ceteris paribus, our ontology turns out to be less ontologically parsimonious than if we reject them. Afterwards, in the third section, I distinguish between maximalist and non-maximalist and reductionist and non-reductionist theories of conjunctive (...) properties., as well as between reductionist and non-reductionist theories that reject conjunctive properties. Such distinctions help to clarify the options at hand when accepting or rejecting conjunctive properties. In light of these distinctions, I then tackle two objections against the argument from ontological parsimony. Finally, in the remaining sections, I deal with two arguments defended by D. M. Armstrong for the existence of conjunctive properties: the argument from infinite complexity and the argument from causal powers. I show that there are several ways to resist these arguments and their conclusion. (shrink)

David Armstrong accepted the following three theses: universals are immanent, laws are relations between universals, and laws govern. Taken together, they form an attractive position, for they promise to explain regularities in nature—one of the most important desiderata for a theory of laws and properties—while remaining compatible with naturalism. However, I argue that the three theses are incompatible. The basic idea is that each thesis makes an explanatory claim, but the three claims can be shown to run in a problematic (...) circle. I then consider which thesis we ought to reject and suggest some general lessons for the metaphysics of laws. (shrink)

Aquinas consistently criticizes Plato and his followers for their commitment to the existence of separate forms or ideas. There is no whiteness existing by itself apart from any particular white things or any particular person's thoughts about them. The same goes for every natural form, from humanity to heat. And yet Aquinas is happy to appeal to such separate forms as examples to illustrate his own metaphysical views. This seems like a strange and dangerous procedure. If Aquinas considers Platonic forms (...) to be incoherent, then surely their incoherence will infect the notions he uses them to illustrate. But does Aquinas consider Platonic forms to be incoherent? I don't think so. The very fact that he uses them as examples to illustrate his own views suggests otherwise. And at one point Aquinas even grants that God could create a Platonic form such as a separate whiteness. Why, then, does he reject such forms? What has Aquinas got against them? An examination of his main critical discussions of Platonic forms shows that he rejects them not because he thinks they are impossible, but because he thinks they are unnecessary. In other words, Aquinas rejects Platonic forms on grounds of parsimony, since he thinks they cannot explain any of the things that Plato posited them to explain, such as the changes things undergo, the nature and existence of things, and our knowledge of them. Where Plato's separate forms fail, however, Aquinas thinks Aristotle's inherent forms succeed. (shrink)

It has long been a standard practice for the natural sciences to classify things. Thus, it is no wonder that, for two and a half millennia, philosophers have been reflecting on classifications, from Plato and Aristotle to contemporary philosophy of science. Some of the results of these reflections will be presented in this chapter. I will start by discussing a parody of a classification, namely: the purportedly ancient Chinese classification of animals described by Jorge Luis Borges. I will show that (...) many of the mistakes that account for the comic features of this parody appear in real-life scientific databases as well. As examples of the latter, I will discuss the terminology database of the National Cancer Institute (NCI) of the United States, the NCI Thesaurus. (shrink)

Is it possible to get by with just one ontological category? We evaluate L.A. Paul's attempt to do so: the mereological bundle theory. The upshot is that Paul's attempt to construct a one category ontology may be challenged with some of her own arguments. In the positive part of the paper we outline a two category ontology with property universals and kind universals. We will also examine Paul's arguments against a version of universal bundle theory that takes spatiotemporal co-location instead (...) of compresence or coinstantiation as the feature by which we can identify genuine bundles. We compare this novel theory, bundle theory with kinds, and Paul's mereological bundle theory and apply them to a case study concerning entangled fermions and co-located bosons. (shrink)

After a general remark about Armstrong’s conception of ontology, I raise objections against this view and defend an alternative account of the connection between particulars and their properties, involving a kind of ontological dependence which is different from Armstrong’s necessary connection between particulars and their properties.

This chapter discusses the distinction between natural kinds and natural properties. Some theorists deny the distinction, and claim that natural kinds can be identified with properties. For example, natural kinds might be understood as the perfectly natural properties, reducible to properties or the extensions of properties. Alternatively, one might argue that natural kinds and natural properties are distinct and that natural kinds could be considered as a sui generis type of entity. For example, one might hold that natural kinds require (...) a distinct kind of universal, substantival universal, or sortal. Alternatively, one might claim that properties themselves form natural kind groupings, in virtue of causal mechanisms. This chapter argues that classification into natural kinds can reflect real differences between natural groups, without the supplementary ontological distinction between properties and kinds. -/- .

In his Moderate Realism and Its Logic (Yale, 1996), Donald Mertz argues that the traditional ontology of nonpredicable substances and predicable universals is beset by “intractable problems,” “harbors an insidious error,” and constitutes a “stumbling block” for the ontologist. By contrast, a onecategory ontology consisting of relation instances (and combinations thereof) is sustainable, and indeed the only way of avoiding commitment to bare particulars. The success of the project turns on Mertz’s claim that every relation instance has a linking aspect, (...) so that (in a sense) even Socrates is a predicate. I argue that, ironically, it is this very feature of a relation instance that undermines Mertz’s entire theory of predication, effectively preventing any connections from being formed between the instances that allegedly compose an ordinary individual such as Socrates.

I provide an argument against the Aristotelian view of universals, according to which universals depend for their existence on their exemplifiers. The argument consists in a set of five jointly inconsistent assumptions. As such, the argument can be used to argue in favour of other conclusions, such as that exemplification is no relation or that plausible principles concerning ontological dependence or grounding do not hold.

Republic 596a introduces a One over Many principle that has traditionally been considered as an argument for the existence of Forms, according to which, one Form should be posited for each like-named plurality. This interpretation was challenged by (Smith, J. A. 1917. “General Relative Clauses in Greek.” Classical Review 31: 69–71.), who interpreted it rather as a statement that each Form is unique and correlated to a plurality of things that have the same name as it. (Sedley, D. 2013. “Plato (...) and the One-over-Many Principle”, in Chiaradonna & Galluzzo 2013, 113–37.) has offered a forceful defence of Smith’s interpretation. I argue that Sedley’s defence fails and that the traditional interpretation should be preferred. (shrink)

I discuss Aristotle’s opening argument against Platonic Forms in _Metaphysics_ A.9, ‘the Razor’, which criticizes the introduction of Forms on the basis of an analogy with a hypothetical case of counting things. I argue for a new interpretation of this argument, and show that it involves two interesting objections against the introduction of Forms as formal causes: one concerns the completeness and the other the adequacy of such an explanatory project.

The Problem of Universals in Contemporary Philosophy. Edited by Gabriele Galluzzo and Michael J. Loux.

G. E. L. Owen, in his infl uential paper “Inherence,” talks of “vink,” a name he has created for a particular shade of the color pink, and this “vink” serves as an individual in the Aristotelian category of quality. Owen was one of the first to aim to discredit the belief that J. L. Ackrill and his camp espoused, the belief that Aristotle thought that “general attributes are not in individuals, particular attributes are not in more than one individual.” I (...) postulate that there is nothing here that does not preclude the existence of transferable nonsubstantial particulars, and base this view on passages from Aristotle’s Categories and certain examples found in Ammonius’s commentary and On Colors. Given this, a nonsubstantial particular of “vink” would not have to rely on having inhered in just one particular body to have existence, however, it would have to inhere in at least one particular body.

Contemporary orthodoxy affirms that singular terms cannot be predicates and that, therefore, ‘is’ is ambiguous as between predication and identity. Recent attempts to treat names as predicates do not challenge this orthodoxy. The orthodoxy was built into the structure of modern formal logic by Frege. It is defended by arguments which I show to be unsound. I provide a semantical account of atomic sentences which draws upon Mill's account of predication, connotation and denotation. I show that singular terms may be (...) predicates, that it is highly implausible that there is an ‘is’ of identity in natural languages, and that modern formal logic is deficient in that it cannot recognize sentences, including singular existentials, in which singular terms are predicates, or inferences which depend upon the logical role rather than the logical category of expressions.

The paper deals with Poinsot’s ontology of universals presented not only in the Material Logic but also in the volume devoted to the Natural Philosophy of his Thomistic Philosophical Course. Currently, it takes into account also the often neglected Theological Course. The author states that there are two different positions as far as the issue of the ontology of universals is concerned, which prima facie lead to the doctrinal tension in Poinsot’s corpus. On one hand, in the Ars Logica, the (...) extramental nature is said to be particularized and only virtually distinct from the individuating grade. On the other, in the Philosophia Naturalis and the Cursus Theologicus, it is supposed to be common to the numerically different singulars and thus really different from individuation. The authorsolves this seeming contradiction by referring to two different levels of the analysis implicit in Poinsot’s treatment of the issue. (shrink)

The discussion of universals in Peter Abelard’s Logica ‘Ingredientibus’ has been interpreted in many ways. Of particular controversy has been the proper way to interpret his use of the term status. In this paper I offer an interpretation of status by comparing Abelard’s account of knowledge of universals to Edmund Husserl’s presentations of categorial and eidetic intuition. I argue that status is meant to be understood as something like an ideal object, in Husserl’s sense of the term. First, I present (...) Abelard’s discussion of status and distinguish this term from universals, things, acts of understanding, and forms. Next, I consider Husserl’s account of categorial and eidetic intuition. Finally, I draw parallels between the two while showing how an interpretation of status as ideal object overcomesthe interpretive problems encountered by other commentators on Abelard. (shrink)

The interpretations in the secondary literature of Suárez’ position in the “classical” debate on the status of universals vary considerably. In this article, the problem is looked at from a slightly different angle: that of Suárez’ basic metaphysics of substantial forms and his views concerning understanding and knowledge. These areas of Suárez’ thought are thoroughly analysed and related to each other. Regarding the question of the status of universals it is argued that Suárez’ thought in the areas of substantial forms (...) and of understanding generally supports the reading of Suarez as a “moderate nominalist”.

The question of the existence of cultural universals immediately leads us to the problem of intercultural communication and of so-called incommensurability. Over the last few decades, these topics have been the subject of controversy in the philosophy of science, and the stock of universalism has been falling as a result of the rise of Kuhn’s paradigm theory and Quine’s thesis of the indeterminacy of translation. Nowadays cultural pluralism or relativism is rather dominant among philosophers and has begun to appear plausible, (...) too, from an anthropological or sociological point of view. But philosophically, as is well known, relativism harbors many difficulties and paradoxes. As philosophers, therefore, we cannot accept imprudent relativism just as it is. (shrink)

With the growing interest in Renaissance studies, it is gratifying to see a major scholarly work on a little known philosopher of the Averroistic trend of Aristotelianism that had its seat in his native city of Bologna. Matsen’s study, whose first draft was submitted as a doctoral dissertation at Columbia University, opens with a summary presentation of Alessandro Achillini’s life and works based on archival documents and other first-hand sources. The body of the work focuses on two major themes: the (...) theory of universals and the concept of transcendentals. All students of philosophy are aware of the importance attached to the problem of universals by medieval schoolmen and the consequences that their solution had on their systems of philosophy. It is likewise known that the meaning and value of such transcendental concepts as being, unity, truth, goodness, and the like played a substantial role in the shaping of medieval metaphysics built mainly along Platonic and Aristotelian lines. The fact that a Renaissance man like Achillini carried on the discussion of both topics to such a degree as to devote an entire Quaestio to the study of universals and the first part of his De distinctionibus to the analysis of the transcendentals, shows, among other things, the extent to which Renaissance thought is indebted to medieval philosophy. What is less known, however, is the impact that William of Ockham, whose influence was felt throughout the entire fourteenth and fifteenth centuries, has also had on Renaissance thinkers, and especially on Achillini. A comparison between Ockham’s position on the nature of both the universals and the transcendentals has led Matsen to conclude that there is a striking similarity of view between Ockham and Achillini on many important issues and that the latter was the principal cause of the revival of Ockhamism at Bologna around 1500.

The ‘theory of universals’ of St. Thomas Aquinas has been interpreted in one of two ways by most commentators. Traditionally, commentators have attributed to Thomas the theory which is usually also attributed to Aristotle: “moderate realism,” the view that universals exist in things, subject in some way to individuating principles in the things. For example, according to Copleston.
