Minimally, causal realism (as understood here) is the view that accounts of causation in terms of mere, regular or probabilistic conjunction are unsatisfactory, and that causal phenomena are correctly associated with some form of de re necessity. Classic arguments, however, some of which date back to Sextus Empiricus and have appeared many times since, including famously in Russell, suggest that the very notion of causal realism is incoherent. In this paper I argue that if such objections seem compelling, it is (...) only because everyday expressions concerning causal phenomena are misleading with respect to certain metaphysical details. These expressions generally make reference to the relations of events or states of affairs, but ignore or obscure the role played by causal properties. I argue that on a proposed alternative, an analysis in terms of causal processes, more refined descriptions of causal phenomena escape the charge of incoherence. Causal necessity is here located in the relations of causal properties. I distinguish this view from the recent process theories of Salmon and Dowe, which are disinterested in causal realism.

Two chief problems of the theory of knowledge are the question of meaning and the question of verification. The first question asks under what conditions a sentence has meaning, in the sense of cognitive, factual meaning. The second one asks how we get to know something, how we can find out whether a given sentence is true or false. The second question presupposes the first one. Obviously we must understand a sentence, i.e. we must know its meaning, before we can (...) try to find out whether it is true or not. But, from the point of view of empiricism, there is a still closer connection between the two problems. In a certain sense, there is only one answer to the two questions. If we knew what it would be for a given sentence to be found true then we would know what its meaning is. And if for two sentences the conditions under which we would have to take them as true are the same, then they have the same meaning. Thus the meaning of a sentence is in a certain sense identical with the way we determine its truth or falsehood; and a sentence has meaning only if such a determination is possible. (shrink)

With the possible exception of causation, disposition concepts are as prevalent in ordinary thought as any of the nomic concepts. Progress on their nature has been hard to come by. No doubt the difficulty of saying anything illuminating and suitably general about their nature is a function of their pervasiveness.

In ‘Finkish Dispositions’1 David Lewis proposes an analysis of dispositions which improves on the simple conditional analysis. In this paper I show that Lewis’ analysis still fails. I also argue that repairs are of no avail, and suggest why this is so.

General metaphysical arguments have been proposed in favour of the thesis that all dispositions have categorical bases (Armstrong; Prior, Pargetter, Jackson). These arguments have been countered by equally general arguments in support of ungrounded dispositions (Molnar, Mumford). I believe that this controversy cannot be settled purely on the level of abstract metaphysical considerations. Instead, I propose to look for ungrounded dispositions in specific physical theories, such as quantum mechanics. I explain why non-classical properties such as spin are best interpreted as (...) irreducible dispositional properties, and I give reasons why even seemingly classical properties, for instance position or momentum, should receive a similar treatment when interpreted in the quantum realm. Contrary to the conventional wisdom, I argue that quantum dispositions should not be limited to probabilistic dispositions (propensities) by showing reasons why even possession of well-defined values of parameters should qualify as a dispositional property. I finally discuss the issue of the actuality of quantum dispositions, arguing that it may be justified to treat them as potentialities whose being has a lesser degree of reality than that of classical categorical properties, due to the incompatibility relations between non-commuting observables.

According to the Doctrine of Divine Conservation, the world could not endure through time were God not actively sustaining its existence. An alternative to the conservationist view is one according to which the existence of whatever is the fundamental material of our universe is characterized by inertia, so that its continuance stands in no need of active causal intervention by some other being. In this article I develop in some detail the Doctrine of Existential Inertia and reply to some of (...) the objections brought against it by conservationists. (shrink)

The doctrine that there are no logically necessary connections in nature can be used to support both occasionalism, according to which God alone can be a cause, and 'anti-occasionalism', according to which God cannot be a cause. Quentin Smith has recently invoked the 'no logically necessary connections in nature' doctrine in support of the latter. I bring two main objections against his thesis that God (logically) cannot be a cause. The first is that there are good reasons to think that (...) there are irreducible dispositions in nature, and that where such dispositions are manifested, there are logically necessary causal connections. The second objection is that even if the 'no logically necessary connections in nature' doctrine is true, one is not forced to deny causal efficacy to God: with no breach in logical propriety, one may embrace occasionalism.

The role of dispositions in the physical world is considered. It is shown that not only can classical physics be reasonably construed as the discovery of real dispositions, but also quantum physics. This approach moreover allows a realistic understanding of quantum processes.

Free-will defenses and theodicies reason that since God’s purpose in creation requires libertarian free will, God cannot prevent every event which occurs as a consequence of the misuse of freedom. However, given libertarian free will and free-will theistic accounts of God’s purpose in creation, I describe (in terms of a dispositions/powers ontology) how it is logically possible for God to achieve his purposes while preventing moral evil. This, then, is a refutation of the free-will defense and related theodicies that should (...) shift the focus of Christian theorizing from God’s ability to God’s goodness. (shrink)

Dispositional properties have been receiving an increasing amount of attention in the last decade from metaphysicians and philosophers of science. The proper semantics and ontology remains controversial. This paper offers an analysis and ontology of dispositional properties rooted in Christology and the biblical doctrine of creation. The analysis overcomes the standard problems faced by all such analyses and provides an account of “ungrounded dispositions.” The analysis involves a version of a Leibnizian-Aristotelian notion of possible worlds and provides a novel notion (...) of truth-makers for subjunctive conditionals.

How does God govern the world? For many theists “laws of nature” play a vital role. But what are these laws, metaphysically speaking? I shall argue that laws of nature are not external to the objects they govern, but instead should be thought of as reducible to internal features of properties. Recent work in metaphysics and philosophy of science has revived a dispositionalist conception of nature, according to which nature is not passive, but active and dynamic. Disposition theorists see particulars (...) as being internally powerful rather than being governed by external laws of nature, making external laws in effect ontologically otiose. I will argue that theists should prefer a dispositionalist ontology, since it leads them toward the theory of concurrentism in divine conservation, rather than occasionalism, and revives the distinction between internal and external teleology. God on this view does not govern the world through external laws of nature, but rather through internal aspects of powerful properties. (shrink)

One standard criticism of the doctrine of continuous creation is that it entails the occasionalist position that God alone is a true cause and that the events we commonly identify as causes are merely the occasions upon which God brings about effects. I begin by clearly stating Malebranche's argument from continuous creation to occasionalism. Next, I examine two strategies for resisting Malebranche's argument – strong and weak concurrentism – and argue that weak concurrentism is the more promising strategy. Finally, I (...) argue that weak concurrentism requires a necessitarian approach to secondary causation. (shrink)

In a previous paper, Thomas V. Morris and I sketched a view on which abstract objects, in particular, properties, relations, and propositions , are created by God no less than contingent, concrete objects. In this paper r suggest a way of extending this account to cover mathematical objects as well. Drawing on some recent work in logic and metaphysics, I also develop a more detailed account of the structure of PRPs in answer to the paradoxes that arise on a naive (...) understanding of the structure ofthe abstract universe.

Many philosophers hold that all dispositions must have independent causal bases. I challenge this view, hence defending the possibility of bare dispositions. In part 1, I explain more fully what I mean by "disposition," "causal basis," and "bare disposition." In part 2, I consider the claim that the concept of a disposition entails that dispositions are not bare. In part 3, I consider arguments, due to Prior, Pargetter, and Jackson, that dispositions necessarily have distinct causal bases. In part 4, I (...) consider arguments by Smith and Stoljar that there can't be bare dispositions because they would make for unwelcome "barely true" counterfactuals. In the end, I find no reason to deny the possibility of bare dispositions. (shrink)

Many years ago, C.B. Martin drew our attention to the possibility of ‘finkish’ dispositions: dispositions which, if put to the test would not be manifested, but rather would disappear. Thus if x if finkishly disposed to give response r to stimulus s, it is not so that if x were subjected to stimulus r, x would give response z; so finkish dispositions afford a counter‐example to the simplest conditional analysis of dispositions. Martin went on to suggest that finkish dispositions required (...) a theory of primitive causal powers; there, I think, he was mistaken. All that they require is an improved conditional analysis, and this improved analysis can be built upon whatever treatments of properties and of laws we may favour on other grounds. (shrink)

Appeals to dispositionality in explanations of phenomena in metaphysics and the philosophy of mind, require that we first agree on what we are talking about. I sketch an account of what dispositionality might be. That account will place me at odds with most current conceptions of dispositionality. My aim is not to establish a weighty ontological thesis, however, but to move the discussion ahead in two respects. First, I want to call attention to the extent to which assumptions philosophers have (...) made about dispositionality are far from innocent. The assumptions incorporate substantive theses that, by constraining the space of acceptable answers to particular philosophical questions, have inhibited the search for answers to those questions. Second, and more positively, I hope to open up the space of possibilities by offering an alternative way of conceiving dispositionality developed by C. B. Martin. (shrink)

My topic is God's activity in the ordinary course of nature. The precise mode of this activity has been the subject of prolonged debates within every major theistic intellectual tradition, though it is within the Catholic tradition that the discussion has been carried on with the most philosophical sophistication. The problem, in its simplest form, is this: Given the fundamental theistic tenet that God is the provident Lord of nature, the First Efficient Cause who creates the universe, sustains it in (...) being, and exists in all things by His essence, presence, and power,1 how exactly do the actions of secondary (i.e., created) causes fit in with God's own activity in the ordinary course of nature? Or, to put it a bit more neutrally, how exactly is God's own action as the First Cause in nature related to the causal activity, if any , of His creatures? (shrink)

The “existential inertia” thesis holds that, once in existence, the natural world tends to remain in existence without need of a divine conserving cause. Critics of the doctrine of divine conservation often allege that its defenders have not provided arguments in favor of it and against the rival doctrine of existential inertia. But in fact, when properly understood, the traditional theistic arguments summed up in Aquinas’s Five Ways can themselves be seen to be (or at least to imply) arguments against (...) existential inertia and in favor of divine conservation. Moreover, they are challenging arguments, to which defenders of the existential inertia thesis have yet seriously to respond. (shrink)

Objects have dispositions. As Nelson Goodman put it, “a thing is full of threats and promises”. But sometimes those threats go unfulfilled, and the promises unkept. Sometimes the dispositions of objects fail to manifest themselves, even when their conditions of manifestation obtain. Pieces of wood, disposed to burn when heated, do not burn when heated in a vacuum chamber. And pastries, disposed to go bad when left lying around too long, won’t do so if coated with lacquer and put on (...) display in a baker ’s window. Any account of what a disposition is, or of what it takes for an object to have a disposition, should be compatible with these commonplace observations. To date, I believe, no adequate account of dispositions has been given, and the aim of this paper is to defend one. (shrink)

The term “Idealism” has been used to characterize a variety of positions in the western philosophical tradition. Plato, the Neoplatonists, Leibniz, Berkeley, Kant, and Hegel, among others, have been interpreted as proponents of some version of philosophical idealism. Idealism is typically viewed as a response to theoretical problems generated by materialism and certain forms of realism. The difficulties involved with making sense of mind and values within a strictly materialist context, materialist explanations of causality, realist accounts of knowledge, and the (...) ontological status of matter itself have provided the grounds for idealist innovations. However, idealist solutions to these problems need not reject materialism or realism in toto. Idealists may incorporate philosophical claims which appear to be consistent with materialist or realist doctrines. For instance, Plato, the Neoplatonists, and Hegel often write about physical, material objects as if they exist as extramental entities—on some interpretations, at least. An idealist of the Berkeleyan sort would reject the notion of extra-mental material bodies as incoherent. Thus, the following questions emerge. (shrink)
