Dispositions

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.This paper was written for a conference on Dispositions and Laws of Nature held at the University of Alabama, Birmingham, 7–8 February 2003; Michael Watkins commented. I have benefited from those comments, from remarks by other participants, and from discussions with David Armstrong and my colleague, David Robb, on the topic. The account sketched here is based on C. B. Martins work on dispositions. See Martin (1992, 1993, 1994, 1997), Martin and Heil (1999), and Martins contribution to Armstrong et al. (1996). The position is developed in detail in Heil (2003).     

Dispositions and subjunctives

It is generally agreed that dispositions cannot be analyzed in terms of simple subjunctive conditionals (because of what are called “masked dispositions” and “finkish dispositions”). I here defend a qualified subjunctive account of dispositions according to which an object is disposed to Φ when conditions C obtain if and only if, if conditions C were to obtain, then the object would Φ ceteris paribus. I argue that this account does not fall prey to the objections that have been raised in the literature.     

Dispositions and Antidotes

C.B. Martin has shown that the simple conditional analysis of disposition concepts (x is disposed at time t to give response r to stimulus s) is in error. This is due to finkish dispositions which are caused to disappear by the stimulus s. David Lewis has proposed an improved analysis which takes account of finkish dispositions by requiring that the appropriate causal basis remains for a sufficiently long time. I argue that Lewis' analysis also fails, because of the existence of antidotes. An antidote to a disposition interferes with its normal operation so that the stimulus does not bring about the usual response. I consider several possible defences of Lewis' analysis and a plausible repair, but find these unsatisfactory. I conclude by suggesting that an analysis of disposition concepts is not available because an unavoidable indexical element (e.g., reference to normal circumstances) is present in explanations of these concepts. In this regard they may be thought of as akin to theoretical or natural kind concepts.     

The Conditional Analysis of Dispositions and the Intrinsic Dispositions Thesis

The idea that dispositions are an intrinsic matter has been popular among contemporary philosophers of dispositions. In this paper I will first state this idea as exactly as possible. I will then examine whether it poses any threat to the two current versions of the conditional analysis of dispositions, namely, the simple and reformed conditional analysis of dispositions. The upshot is that the intrinsic nature of dispositions, when properly understood, doesn't spell trouble for either of the two versions of the conditional analysis of dispositions. Along the way, I will propose an extensionally correct and practically useful criterion for identifying nomically intrinsic dispositions and criticize one objection raised by Lewis against the simple conditional analysis of dispositions.     

Finkish Dispositions

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.     

Bird on Dispositions and Antidotes

In The Philosophical Quarterly , 48 (1998), Alexander Bird raises an objection against the conditional analysis of dispositions: where an 'antidote' is present all the supposed conditions for manifestation of a disposition are fulfilled but the manifestation does not occur. But Bird's argument suffers from equivocation. If we spell out properly whether the disposition's conditions are to include the presence of the antidote or not, the apparent counter-examples disappear. So his examples do not undermine the conditional analysis of dispositions; they show merely that we need to be careful about describing the examples consistently.     

Dispositions And Mimickers

In this paper I put forward a counterexample against Lewis’s reformed conditional analysis of fragility and then refute a possible response by Lewis. And I go on to argue that Lewis can overcome the counterexample by excluding fragility-mimickers from the stimulus appropriate to the concept of fragility.     

Dispositions and the Trojan Fly

A detailed consideration of the Trojan fly supertask reveals certain unsuspected characteristics relating to determinism and causation. I propose here a solution to the new difficulty in terms of bare dispositions.     

Dispositions of the Will

According to Aquinas (1888–1906), the virtue of justice is a habit, that is to say, a stable disposition of the will. Many commentators have found this claim to be puzzling, since it is difficult to see what this might entail, beyond a simple tendency to choose and act in accordance with precepts of justice. However, this objection does not take account of the fact that for Aquinas, the will is the principle of human freedom, and as such, it is expressed through, but not limited to a capacity for particular choices and actions. It therefore needs stable dispositions, towards characteristic aims, in order to function effectively. This paper sets out a case for the cogency of Aquinas’s overall account of the will and its dispositions, by way of an examination of familiar expressions of human freedom which cannot be reduced to a series of individual choices and acts. It then turns to a closer examination of Aquinas’ analysis of the will, arguing that Aquinas’ claims about the orientation of the will towards some overarching and comprehensive good can fruitfully be understood in terms of this expansive conception of human freedom.     

Static And Dynamic Dispositions

When it comes to scientific explanation, our parsimonious tendencies mean that we focus almost exclusively on those dispositions whose manifestations result in some sort of change – changes in properties, locations, velocities and so on. Following this tendency, our notion of causation is one that is inherently dynamic, as if the maintenance of the status quo were merely a given. Contrary to this position, I argue that a complete concept of causation must also account for dispositions whose manifestations involve no changes at all, and that a causal theory that fails to include these ‘static’ dispositions alongside the dynamic ones renders static occurrences miraculous.
