This is a perfect overview article that serves as a general introduction to the topic of dispositions. It is composed of six sections that review the main philosophical approaches to the most important questions: Analysis of disposition ascription, the dispositional/categorical distinction, dispositions and categorical bases, the intrinsicness of dispositions and the causal efficacy of dispositions.

Stephen Mumford puts forward a new theory of dispositions, showing how central their role is in metaphysics and philosophy of science. Much of our understanding of the physical and psychological world is expressed in terms of dispositional properties--from the solubility of sugar to the belief that zebras have stripes. Mumford discusses what it means to say that something has a property of this kind, and how dispositions can possibly be real things in the world. His clear, straightforward, realist account reveals (...) them to be less mysterious than they seem, and shows that an understanding of dispositions is essential to an understanding of properties, causation, and scientific laws.

We argue that desire is an attitude that relates a person not to one proposition but rather to two, the first of which we call the object of the desire and the second of which we call the condition of the desire. This view of desire is initially motivated by puzzles about conditional desires. It is not at all obvious how best to draw the distinction between conditional and unconditional desires. In this paper we examine extant attempts to analyse conditional (...) desire. From the failures of those attempts, we draw a moral that leads us to the correct account of conditional desires. We then extend the account of conditional desires to an account of all desires. We attempt to explain the distinction between intrinsic and extrinsic desire in light of our account of desire. We show how to use our account to solve Wollheim’s paradox of democracy and to save modus ponens. Finally, we extend the account of desire to related phenomena, such as conditional promises, intentions, and commands. (shrink)

Causation is everywhere in the world: it features in every science and technology. But how much do we understand it? Mumford and Anjum develop a new theory of causation based on an ontology of real powers or dispositions. They provide the first detailed outline of a thoroughly dispositional approach, and explore its surprising features.

In this paper, I will discuss the various ways in which intentions can be said to be conditional, with particular attention to the internal conditions on the intentions’ content. I will first consider what it takes to carry out a conditional intention. I will then discuss how the distinctive norms of intention apply to conditional intentions and whether conditional intentions are a weaker sort of commitments than the unconditional ones. This discussion will lead to the idea of what I call (...) the ‘deep structure’ of intentions. Roughly, this is the idea that the conditional nature of our intentions is only partially made explicit in the expressions we use to communicate our intentions and in the explicit form of our thinking about and reasoning with them. Most conditions that qualify our intentions are part of a deep functional structure that can be evinced by observing the actual psychological functioning of intentions and by considering the rational requirements that they engage. I will argue that the deep structure of intentions is characteristically conditional. Genuinely unconditional intentions are only limiting instances of conditional intentions and their contribution to agency can only be understood in light of this fact. I will conclude by showing that the characteristic conditional structure of intentions is intimately related to distinctive features of human agency, especially to its unity over time. (shrink)

Counterfactuals is David Lewis' forceful presentation of and sustained argument for a particular view about propositions which express contrary to fact conditionals, including his famous defense of realism about possible worlds and his theory of laws of nature.

What happens to our conception of mind and rational agency when we take seriously future-directed intentions and plans and their roles as inputs into further practical reasoning? The author's initial efforts in responding to this question resulted in a series of papers that he wrote during the early 1980s. In this book, Bratman develops further some of the main themes of these essays and also explores a variety of related ideas and issues. He develops a planning theory of intention. Intentions (...) are treated as elements of partial plans of action. These plans play basic roles in practical reasoning, roles that support the organization of our activities over time and socially. Bratman explores the impact of this approach on a wide range of issues, including the relation between intention and intentional action, and the distinction between intended and expected effects of what one intends.

This paper discusses the prospects of a dispositional solution to the Kripke–Wittgenstein rule-following puzzle. Recent attempts to employ dispositional approaches to this puzzle have appealed to the ideas of finks and antidotes—interfering dispositions and conditions—to explain why the rule-following disposition is not always manifested. We argue that this approach fails: agents cannot be supposed to have straightforward dispositions to follow a rule which are in some fashion masked by other, contrary dispositions of the agent, because in all cases, at least (...) some of the interfering dispositions are both relatively permanent and intrinsic to the agent. The presence of these intrinsic and relatively permanent states renders the ascription of a rule-following disposition to the agent false. (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)

Al is nearly finished sweeping his kitchen floor when he notices, on a counter, a corkscrew that should be put in a drawer. He intends to put the corkscrew away as soon as he is finished with the floor; but by the time he returns the broom and dustpan to the closet, he has forgotten what he intended to do. Al knows (or has a true belief) that there is something he intended to do now in the kitchen. He gazes (...) around the room and tries to recall what it was. Within a minute or so, without seeing the corkscrew, Al recalls. He puts the corkscrew away. Did Al have an intention to put the corkscrew away that persisted from the time he acquired the intention until he put the corkscrew away? That is one of my guiding questions in this article.

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)

Is it possible that one and the same object x has opposing dispositions at the same time? One's first reaction might be that it is evidently impossible. On the assumption that x is incombustible, it seems to follow that it is not combustible. Surprisingly enough, however, it is claimed that there are a number of examples in support of the possibility of simultaneous co-instantiation of opposing dispositions. In this paper, I will bring under scrutiny some of the examples and come (...) to the conclusion that none of them achieve the desired goal. This will give support to the initial intuition that opposing dispositions cannot be co-instantiated by one and the same object at the same time. (shrink)

For the last several decades, dispositional properties have been one of the main topics in metaphysics. Still, however, there is little agreement among contemporary metaphysicians on the nature of dispositional properties. Apparently, though, the majority of them have reached the consensus that dispositional ascriptions cannot be analysed in terms of simple counterfactual conditionals. In this paper it will be brought to light that this consensus is wrong. Specifically, I will argue that the simple conditional analysis of dispositions, which is generally (...) thought to be dead, is in fact an adequate analysis of dispositions. I will go on to discuss Mumford’s view of dispositions from the perspective of the simple conditional analysis of dispositions. (shrink)

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.

Suppose that you intend to go to the theater. Are you therein intending the unconditional proposition that you go to the theater? That would seem to be deeply irrational; after all, you surely do not intend to go if, for instance, in the next instant an earthquake is going to devastate the city. What we intend we do not intend ‘no matter what,’ it is often said. But if so—how can anyone ever rationally intend simply to perform an action of (...) a certain kind? In response to the puzzle, a ‘conditionality’ view of intention has emerged: the contents of everyday intentions are claimed to be fraught with hidden conditional clauses. The paper argues that such claims are radically unmotivated: even unconditional intentions have only limited inferential import and hence contrast sharply with a ‘no matter what’ stance. The point is established by examining relevant patterns of reasoning from unconditional to conditional intentions. (shrink)

The doctrine of promissory fraud holds that a contractual promise implicitly represents an intent to perform. A promisor's conditional intent to perform poses a problem for that doctrine. It is clear that some undisclosed conditions on the promisor's intent should result in liability for promissory fraud. Yet no promisor intends to perform come what may, so there is a sense in which all promisors conditionally intend to perform. Building on Michael Bratman's planning theory of intentions, this article provides a theoretical (...) account of the distinction between “foreground” and “background” conditions on intentions in general and then explains why foreground conditions on a promisor's intent to perform are likely to result in material promissory misrepresentation, while background conditions are not. The difference between foreground and background conditions lies in whether the agent accepts the satisfaction of the condition for the purposes of her practical reasoning. A promisor's nonacceptance of a condition on her intent to perform is material because it is likely to affect her preperformance deliberations and investment in the transaction, as well as her willingness to seek agreement with the promisee on how to fill contractual gaps.

Dispositional ascriptions do not entail the counterfactuals we might expect, as interfering factors may be poised to prevent the disposition from manifesting in its very stimulus conditions. Such factors are commonly called finks and masks. It is thought, however, that finks and masks cannot be intrinsic to the disposition bearer; if an intrinsic property of the object would prevent a particular response in certain conditions, the object fails to have the corresponding disposition. I argue that we should accept intrinsic finks (...) and masks if we think there are finks and masks at all, and also if we maintain that paradigmatic dispositions are intrinsic. This last point is particularly problematic for the claim that there cannot be intrinsic finks and masks, for if paradigmatic dispositions are not intrinsic then the central argument for the impossibility of intrinsic finks and masks is undermined.

A report of a person's desire can be true even if its embedded clause underspecifies the content of the desire that makes the report true. It is true that Fiona wants to catch a fish even if she has no desire that is satisfied if she catches a poisoned minnow. Her desire is satisfied only if she catches an edible, meal-sized fish. The content of her desire is more specific than the propositional content of the embedded clause in our true (...) report of her desires. Standard semantic accounts of belief reports require, however, that the embedded clause of a true belief report specify precisely the content of the belief that makes it true. Such accounts of belief reports therefore face what I call "the problem of underspecification" if they are extended to desire reports. Such standard accounts are sometimes refined by requiring that a belief report can be true not only if its subject has a belief with precisely the propositional content specified by its embedded clause, but also only if its subject grasps that content in a particular way. Such refinements do not, however, help to address the problem of underspecification for desire reports. (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.

A disposition mask is something that prevents a disposition from manifesting despite the occurrence of that disposition’s characteristic stimulus, and without eliminating that disposition. Several authors have maintained that masks must be things extrinsic to the objects that have the masked dispositions. Here it is argued that this is not so; masks can be intrinsic to the objects whose dispositions they mask. If that is correct, then a recent attempt to distinguish dispositional properties from so-called categorical properties fails.

Mumford puts forward a new theory of dispositions, showing how central their role in metaphysics and philosophy of science is. Much of our understanding of the physical and psychological world is expressed in terms of dispositional properties--from the spin of a sub-atomic particle to the solubility of sugar. Mumford discusses what it means to say that something has a property of this kind and how dispositions can possibly be real things in the world.
