Leading scholars discuss the development and application of theories of causation and explanation, offering a state-of-the-art view of current work on these two ...

I compare the failure of counterfactual dependence as a criterion of event causation to the failure of stochastic dependence as a criterion of causal law. Counterexamples to the stochastic analysis arise from cases of Simpson's Paradox, and Nancy Cartwright has suggested a way of transforming the stochastic analysis into something that avoids these counterexample. There is an analogical relationship between cases of Simpson's Paradox and cases of causal overdetermination. I exploit this analogical relationship to motivate my own view about the (...) connection between counterfactuals and event causation. According to my view, counterfactuals and event causation are intimately connected by a principle which falls short of being an analysis but which, as I show, correctly handles not only overdetermination but common causes as well.

This paper is an investigation into the notion of degree of influence, and its application to the problem of pre-emption. In 'Causation as Influence', Lewis presented a new account of causation under determinism and some new observations on the problem of pre-emption. He claimed that, in cases of pre-emption, the pre-empting cause is much more of a cause than its pre-empted alternative; it has much more influence. I begin by trying to make sense of the notion of degree of influence. (...) Then I emend Lewis's approach to pre-emption in response to objections, compare it to Kvart's Sustainably Reducible Influence account, and finally conclude that all these accounts fail to solve the problem of pre-emption.

Causation is a deeply intuitive and familiar relation, gripped powerfully by common sense. Or so it seems. But as is typical in philosophy, deep intuitive familiarity has not led to any philosophical account of causation that is at once clean, precise, and widely agreed upon. Not for lack of trying: the last 30 years or so have seen dozens of attempts to provide such an account, and the pace of development is, if anything, accelerating. (See Collins, Hall and Paul 2003a (...) for a comprehensive sampling of the latest work.) It is safe to say that none has yet succeeded. It is also safe to say that the effort put into their development has yielded a wealth of insights into causation. And it is, arguably, from the study of causal preemption—cases that feature multiple competing candidates for the title of “cause” of some given effect—that the greatest such wealth has flowed. These cases come in a number of varieties: so-called early and late preemption, symmetric overdetermination, and trumping preemption. Collectively, they place extremely severe constraints on any philosophical account of causation that can successfully handle them. One of the lessons they have to teach, then, is a lesson about the form that a successful analysis of causation must have. There is a deeper lesson, a lesson about the nature of causation itself, or if you like, about the workings of our causal concept. It emerges from close study of the struggles that extant accounts face in trying to provide even remotely attractive treatments of causal preemption. It is this: There appears to be a significant and perhaps intractable tension between one strand in our thinking about causation—a strand that emphasizes the need for causes to be connected to their effects via intervening processes with the right intrinsic character—and another—one that emphasizes the claim that effects in some sense depend on their causes. By the end of this essay, this tension will be vividly apparent.. (shrink)

In response to counterexamples involving late preemption, David Lewis (1986) revised his original (1973) counterfactual analysis of causation to include the notion of quasi-dependence. Jonardon Ganeri, Paul Noordhof and Murali Ramachandran (1998) argue that their ‘PCA*-analysis’ of causation solves the problem of late preemption and is superior to Lewis’s analysis. I show that neither quasi-dependence nor the PCA*-analysis solves the problem of late preemption.

Extant counterfactual accounts of causation (CACs) still cannot handle preemptive causation. I describe a new variety of preemption, defend its possibility, and use it to show the inadequacy of extant CACs. Imagine that it is a law of nature that the first spell cast on a given day match the enchantment that midnight.

Cases of overdetermination or preemption continue to play an important role in the debate about the proper interpretation of causal claims of the form "C was a cause of E". I argue that the best treatment of preemption cases is given by Mackie's venerable INUS account of causal claims. The Mackie account suffers, however, from problems of its own. Inspired by its ability to handle preemption, I propose a dramatic revision to the Mackie account – one that Mackie himself would (...) certainly have rejected – to solve these difficulties. The result is, I contend, a very attractive account of singular causal claims. (shrink)
