Does A cause B simply if A prevents what would have prevented B? Such a case is known as double prevention: where we have the prevention of a prevention. One theory of causation is that A causes B when B counterfactually depends on A and, as there is such a dependence, proponents of the view must rule that double prevention is causation.<br><br>However, if double prevention is causation, it means that causation can be an extrinsic matter, that the cause and effect need not be connected by a continuous chain of events, that there can be causation by absence, and that there can be causation at a distance. All of these implications jar with strong intuitions we have about the nature of causation. There is, on the other hand, a theory of causation based on an ontology of real dispositions, where causation involves the passing around of powers. This theory in contrast entails that double prevention is not causation and, on this issue, it can claim a victory over the counterfactual dependence account.

There are a number of dispositionalist solutions to the free will problem based on freedom consisting in the agent's exercise of a power. But if a subject a is free when they exercise their power P, there is an objection to be overcome from the possibility of power implantation. A brainwasher, rather than directly manipulating a subject's movements, can instead implant in them a desire, to be understood as a disposition to act, and allow the subject to exercise such a power. It seems that, according to the dispositionalist theory of freedom, such an agent would still count as acting freely. There is a strong non-consent intuition that a is not free in such a case because they did not consent to having the power P—the desire in question. Filling out this intuition is not straightforward. But it can be done in terms of the exercise of P being regulated by higher-order powers of self-reflection. Such regulation is what allows an agent to either take ownership of a power or to reject it

In Watching Sport, Stephen Mumford distinguishes two ways in which sport can be seen. A purist sees it aesthetically while a partisan sees it competitively. But this overlooks the obvious point that most sports fans are neither entirely purist nor entirely partisan. The norm will be some moderate position in between with the purist and partisan as ideal limits. What is then the point of considering these pure aesthetic and pure competitive ways of seeing? In this discussion note, I consider possible accounts of the way in which the moderate spectator watches. After rejecting what I call a pure perception theory and a mixed view, I defend an oscillation theory. This means that the moderate sports fan is one who switches, sometimes rapidly, between the aesthetic and competitive perceptions of sport. A pay-off of this account is that we do not need a further, third way of perceiving sport in order to account for the moderate. It has been explained in terms of our original two forms of perception. This fills a lacuna in Mumford's account

In this paper I aim to make sense of our pre‐theoretic intuitions about dispositions by presenting an argument for the identity of a disposition with its putative categorical base. The various possible ontologies for dispositions are outlined. The possibility of an empirical proof of identity is dismissed. Instead an a priori argument for identity is adapted from arguments in the philosophy of mind. I argue that dispositions occupy, by analytic necessity, the same causal roles that categorical bases occupy contingently and that properties with identical causal roles are identical. The validity of the argument depends upon the possibility of overdetermination of disposition manifestations being rejected. ‘Ungrounded dispositions’ are dismissed as not genuine dispositions. Identity conditions for dispositions and categorical bases are outlined

If one’s solution to the free will problem is in terms of real causal powers of agents then one ought to be an incompatibilist. Some premises are contentious but the following new argument for incompatibilism is advanced: 1. If causal determinism is true, all events are necessitated2. If all events are necessitated, then there are no powers3. Free will consists in the exercise of an agent’s powersTherefore, if causal determinism is true, there is no free will; which is to say that free will is incompatible with determinism, so compatibilism is false

The results of sport would not interest us if either they were necessitated or they were a matter of pure chance. And if either case were true, the playing of sport would seem to make no sense either. This poses a dilemma. But there is something between these two options, namely the dispositional modality. Sporting prowess can be understood as a disposition towards victory and sporting liabilities a disposition towards defeat. The sporting contest then pits these net prowesses against each other. The stronger will tend to beat the weaker but no more than tend. This makes sense of the sporting contest in which the weaker knows they still can win. The stronger team can lose though they do not tend to do so. The dilemma is thus escaped

[EN]Most theories of causation assume that it must involve some kind of necessity, or that the cause must be entirely sufficient for the effect. Others have already suggested that it should be possible to get a theory of causation from a theory of powers or dispositions. Such a project is far from complete but even here we find that the key point in a dispositional theory of causation has been lacking. This paper attempts to establish some of the most important principles of such a theory and in so doing turn the existing discussion in a new direction. [ES]La mayoría de las teorías de causación asumen que debe envolverse algún tipo de necesidad, o que la causa debe ser enteramente suficiente para el efecto. Otros ya han sugerido que debería de ser posible obtener una teoría de causación a partir de una teoría de poderes o disposiciones. Un proyecto tal está muy lejos de estar completo, pero incluso aquí encontramos que ha faltado el punto clave en una teoría dispositiva de causación. Este escrito intenta establecer algunos de los principios más importantes de una teoría tal, y al hacerlo inclina la discusión existente en una nueva dirección.
