Substratum Theories

Several metaphysical debates have typically been modeled as oppositions between a relationist approach and a substantivalist approach. Such debates include the Bundle Theory and the Substratum Theory about ordinary material objects, the Bundle (Humean) Theory and the Substance (Cartesian) Theory of the Self, and Relationism and Substantivalism about time. In all three debates, the substantivalist side typically insists that in order to provide a good treatment of the subject-matter of the theory (time, Self, material objects), it is necessary to postulate (...) the existence of a certain kind of substance, while the other side, the relationist one, characteristically feels that this is an unnecessary expense and that one can get the job done in an ontologically cheaper way just with inter-related properties or events. In this paper I shall defend the view that there is much less of a disagreement between relational ontologies and substantival ontologies than it is usually thought. I believe that, when carefully examined, the two sides of the debate are not that different from each other, in all three cases of pairs of views mentioned above. As we will see, both the relational side and the substantival side work in the same way, suffer from and answer the same objections, and are structurally extremely similar. It will be an important question – one that I shall discuss in detail, and that is indeed the main point of interest for me in this paper – whether this means that the two sides of the debate are somehow 'equivalent' or not, and what 'equivalent' could mean.

In this article I try to show that the most deep level ontology can have rich meaning for our understanding of such practical and everyday phenomena as education and interaction. With this deep level ontology I mean the problem of universals. Starting from famous traditional stances of realism and nominalism, which both are for the modern theories of growth and Bildung, I continue to the third and more recently developed ontological theory, trope theory according to which the properties (qualities, relations (...) etc.) are real (unlike in nominalism) but not universal (like in realisms). Then I will take a closer look at the trope theory of CB Martin. According to it every causal event is an interaction event between simple or complex beings in which their existing dispositions may produce manifesting properties. This point of view is radically anti dualistic because that basic level causal interaction has in the simplified forms all the elements of semiotic, meaningful of mental activity of such complex beings likes humans and animals. Ome of the main general conclusions of the article is that all causal affections contain a kind of “interpretation” from the side of affected object. (shrink)

In this paper, I explore several versions of the bundle theory and the substratum theory and compare them, with the surprising result that it seems to be true that they are equivalent (in a sense of 'equivalent' to be specified). In order to see whether this is correct or not, I go through several steps : first, I examine different versions of the bundle theory with tropes and compare them to the substratum theory with tropes by going through various standard (...) objections and arguing for a tu quoque in all cases. Emphasizing the theoretical role of the substratum and of the relation of compresence, I defend the claim that these views are equivalent for all theoretical purposes. I then examine two different versions of the bundle theory with universals, and show that one of them is, here again, equivalent to the substratum theory with universals, by examining how both views face the famous objection from Identity of Indiscernibles in a completely parallel way. It is only the second, quite extreme and puzzling, version of the bundle theory with universals that is not be equivalent to any other view; and the diagnosis of why this is so will show just how unpalatable the view is. Similarly, only a not-so-palatable version of the substratum theory is genuinely different from the other views; and here again it's precisely what makes it different that makes it less appealing.

Les propriétés matérielles sont généralement appréhendées comme les propriétés d’une substance matérielle : cette chemise possède la propriété d’être bleue, cette chaussure la propriété d’être en bon état. Pourtant, on peut trouver plusieurs raisons de douter que les propriétés soient nécessairement les propriétés d’une substance matérielle, à la fois en métaphysique avec la théorie du faisceau, et en physique contemporaine à travers les notions d’énergie du vide et de champ. Or, si les propriétés ne sont pas les propriétés de substances (...) matérielles, on peut s’interroger sur la théorie de l’instanciation qu’implique une telle thèse. Dans cet essai, je m’emploierai à examiner la cohérence et la plausibilité de la thèse selon laquelle certaines, voir toutes les propriétés matérielles ne sont pas instanciées par une substance et la théorie de l’instanciation qui en découle. | : Material properties are generally construed as properties of material substances : this shirt has the property of being blue, these shoes are in good condition. However, one could think of several reasons to doubt that properties necessarily are properties of material substances both in metaphysics, with the bundle theory, and in contemporary physics, through the two notions of field and energy of the vacuum. But, if properties are not properties of material substances, what is the resulting theory of instantiation? Within the scope of this article, I will examine the consistence and plausibility of the view that several, if not all of, material properties are not instantiated by a substance and the theory of instantiation which follows from it.

There is a largely unrecognized ambiguity concerning the nature of a trope. Disambiguation throws into relief two fundamentally different conceptions of a trope and provides two ways to understand and develop each metaphysical theory that put tropes to use. In this paper I consider the relative merits that result from differences concerning a trope’s ability to ground the character of ordinary objects. I argue that on each conception of a trope, there are unique implications and challenges concerning character-grounding.

In this paper I explore Michael Loux’s important distinction between “tropes” and “tropers”. First, I argue that the distinction throws into relief an ambiguity and discrepancy in the literature, revealing two fundamentally different versions of trope theory. Second, I argue that the distinction brings into focus unique challenges facing each of the resulting trope theories, thus calling into question an alleged advantage of trope theory—that by uniquely occupying the middle ground between its rivals, trope theory is able to recover and (...) preserve the insights of these views. Ultimately, the distinction suggests that trope theory is a divided house. (shrink)

Trope theory is an increasingly prominent contender in contemporary debates about the existence and nature of properties. But it suffers from ambiguity concerning the nature of a trope. Disambiguation reveals two fundamentally different concepts of a trope: modifier tropes and module tropes. These types of tropes are unequally suited for metaphysical work. Modifier tropes have advantages concerning powers, relations, and fundamental determinables, whereas module tropes have advantages concerning perception, causation, character-grounding, and the ontology of substance. Thus, the choice between modifier (...) tropes and module tropes is significant and divides the advantages of trope theory simpliciter. In addition, each resulting trope theory is unstable: modifier trope theory threatens to collapse into realism and module trope theory threatens to collapse into austere nominalism. This invites reflection on the stability of trope theory in general. (shrink)

A critical survey of the main metaphysical theories concerning the nature of material objects (substratum theories, bundle theories, substance theories, stuff theories) and their identity conditions, both synchronic (monist vs. pluralist theories) and diachronic (three-dimensionalism, four-dimensionalism, sequentialism).

My general aim in this paper is to shed light on the controversial concept of a bare particular. I do so by arguing that bare particulars are best understood in terms of the individuative work they do within the framework of a realist constituent ontology. I argue that outside such a framework, it is not clear that the notion of a bare particular is either motivated or coherent. This is suggested by reflection on standard objections to bare particulars. However, within (...) the framework of a realist constituent ontology, bare particulars provide for a coherent theory of individuation—one with a potentially significant theoretical price tag, but one that also has advantages over rival theories. (shrink)

An argument to the effect that, under a few reasonable assumptions, the bare particular ontology is best understood in terms of supersubstativalism: objects are identical to regions of space(-time) and properties directly inhere in space(-time) points or region as their bearers.

Abstract: There are two traditionally rival views about the nature of time: substantivalism that takes time to be a substance that exists independently of events located in it, and relationism that takes time to be constructed out of events. In this paper, first, I want to make some progress with respect to the debate between these two views, and I do this mainly by examining the strategies they use to face the possibilities of ‘empty time’ and ‘time without change’. As (...) we shall see, the two allegedly very different rival views are much less different than has been thought: their structure is extremely similar, their strategies are extremely similar, and they can both face the possibilities of ‘empty time’ and ‘time without change’ in the same way. Thus, I argue in favour of a certain kind of equivalence between the two views; I discuss a Strong and a Weak version of this claim; and I provide reasons for endorsing the former. I also discuss the parallel between this pair of views about the nature of time and another analogous pair of views: the bundle theory and the substratum theory about the nature of material objects, with respect to the problem with Identity of Indiscernibles.

This Thesis engages with contemporary philosophical controversies about the nature of dispositional properties or powers and the relationship they have to their non-dispositional counterparts. The focus concerns fundamentality. In particular, I seek to answer the question, ‘What fundamental properties suffice to account for the manifest world?’ The answer I defend is that fundamental categorical properties need not be invoked in order to derive a viable explanation for the manifest world. My stance is a field-theoretic view which describes the world as (...) a single system comprised of pure power, and involves the further contention that ‘pure power’ should not be interpreted as ‘purely dispositional’, if dispositionality means potentiality, possibility or otherwise unmanifested power or ability bestowed upon some bearer. The theoretical positions examined include David Armstrong’s Categoricalism, Sydney Shoemaker’s Causal Theory of Properties, Brian Ellis’s New Essentialism, Ullin Place’s Conceptualism, Charles Martin’s and John Heil’s Identity Theory of Properties and Rom Harré’s Theory of Causal Powers. The central concern of this Thesis is to examine reasons for holding a pure-power theory, and to defend such a stance. This involves two tasks. The first requires explaining what plays the substance role in a pure-power world. This Thesis argues that fundamental power, although not categorical, can be considered ontologically-robust and thus able to fulfil the substance role. A second task—answering the challenge put forward by Richard Swinburne and thereafter replicated in various neo-Swinburne arguments—concerns how the manifestly qualitative world can be explained starting from a pure-power base. The Light-like Network Account is put forward in an attempt to show how the manifest world can be derived from fundamental pure power. (shrink)

Gonzalo Rodriguez-Pereyra offers a fresh philosophical account of properties. How is it that two different things (such as two red roses) can share the same property (redness)? According to resemblance nominalism, things have their properties in virtue of resembling other things. This unfashionable view is championed with clarity and rigor.

I defend an interpretation of Locke’s remarks on substratum according to which substrata not only have sensible qualities but are just familiar things and stuffs: horses, stones, gold, wax, and snow. The supporting relation that holds between substrata and the qualities that they support is simply the familiar relation of having, or instantiating, which holds between a particular substance and its qualities. I address the obvious objection to the interpretation -- namely, that it cannot be reconciled with Locke’s claim that (...) the idea substratum is an obscure, confused idea of we know not what -- and I identify numerous textual parallels between Locke's discussions of substrata and particular substances which strongly support the deflationary interpretation.

In a recent paper, Jiri Benovsky argues that the bundle theory and the substratum theory, traditionally regarded as ‘deadly enemies’ in the metaphysics literature, are in fact ‘twin brothers’. That is, they turn out to be ‘equivalent for all theoretical purposes’ upon analysis. The only exception, according to Benovsky, is a particular version of the bundle theory whose distinguishing features render unappealing. In the present reply article, I critically analyse these undoubtedly relevant claims, and reject them.
