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 ...

The present essay aims to show how our thinking about explanation has evolved and where it stands now. Its first part presents how some major thinkers, from Aristotle, through to Descartes, Leibniz, Newton, Hume and Kant, to Mill, conceived of explanation. The second part offers a systematic examination of the most significant and controversial contemporary models of explanation. The first part starts with Aristotle’s conception—the thought that explanation consists in finding out why something happened and that answering why-questions requires finding causes—which set the agenda for almost all subsequent thinking about explanation. It discusses the links between laws of nature, causation and explanation in the thought of the early modern philosophers and culminates with John Stuart Mill’s first well-worked out model of scientific explanation, which was based on the idea that there is no necessity in nature and that, ultimately, explanation amounts to unification into a comprehensive deductive system, whose axioms capture the fundamental laws of nature. The second part starts with the Logical Empiricists’ attempt to legitimise the concept of causation by subsuming it under the concept of a deductive-nomological argument. It moves on to discuss the reappearance of genuinely causal models of explanation as well as the re-appearance and development of the Millian idea that explanation amounts to unification. It ends with the examination of teleological approaches to explanation.

Woodward's long awaited book is an attempt to construct a comprehensive account of causation explanation that applies to a wide variety of causal and explanatory claims in different areas of science and everyday life. The book engages some of the relevant literature from other disciplines, as Woodward weaves together examples, counterexamples, criticisms, defenses, objections, and replies into a convincing defense of the core of his theory, which is that we can analyze causation by appeal to the notion of manipulation.

This paper offers a critique of the view that causation can be analyzed in terms of explanation. In particular, the following points are argued: (1) a genuine explanatory analysis of causation must make use of a fully epistemological-psychological notion of explanation; (2) it is unlikely that the relatively clear-cut structure of the causal relation can be captured by the relatively unstructured relation of explanation; (3) the explanatory relation does not always parallel the direction of causation; (4) certain difficulties arise for any attempt to construct a nonrelativistic relation of causation from the essentially relativistic relation of explanation; and (5) to analyze causation as explanation is to embrace a form of “causal idealism”, the view that causal connections are not among the objective features of the world. The paper closes with a brief discussion of the contrast between the two fundamentally opposed viewpoints about causality, namely causal idealism and causal realism.

I argue against a priori objections to the view that causation may be reducible to some micro-structural process in principle discoverable by physics. I distinguish explanation from causation, and argue that the main objections to such a reduction stem from conflating these two notions. Explanation is the collection of pragmatically relevant, possibly counterfactual information about causation; and causation is to be identified in a necessary a posteriori way with whatever physical processes underwrite our explanatory claims.

Instances of negative causation—preventions, omissions, and the like—have long created philosophical worries. In this paper, I argue that concerns about negative causation can be addressed in the context of causal explanation generally, and mechanistic explanation specifically. The gravest concern about negative causation is that it exacerbates the problem of causal promiscuity—that is, the problem that arises when a particular account of causation identifies too many causes for a particular effect. In the explanatory context, the problem of promiscuity can be solved by characterizing the phenomenon to be explained as a contrast between two or more events or non-events. This contrastive strategy also can solve other problems that negative causation presents for the leading accounts of mechanistic explanation. Along the way, I argue that to be effective, accounts of causal explanation must incorporate negative causation. I also develop a taxonomy of negative causation and incorporate each variety of negative causation into the leading accounts of mechanistic explanation.

In recent years philosophy of science has seen a resurgence of interest in metaphysical issues, especially those concerning laws, causation,and explanation. Although this book takes only the latter two words for its title, it is also about laws of nature. It is divided into three sections: the first is on causation, the second is on laws, and the third is on explanation: this is entirely appropriate because the debates about them are closely related. Ever since Hume argued that causation is nothing more than regularities, laws have been more respectable than causes in philosophy. Perhaps this is also because science is replete with specially named laws which seem to play a central role in theories and explanations. Yet, as many philosophers have recently pointed out, contrary to Russell’s famous pronouncement that causation is a relic of a bygone age (quoted p. 3 by Psillos), the contemporary special sciences are very much concerned with the identification and investigation of all manner of causal structures. This raises the question of whether the apparent causal powers attributed to kinds in the special sciences are anything over and above a way of talking about the result of the operations of physical laws governing their microconstituents. Hence the logical empiricist’s project of showing how the laws of the special sciences reduce to those of physics. On their view, explanation, and in particular causal explanation, is nothing more than argument using the laws of nature as premises. However, this coveringlaw model of explanation has been subjected to intense criticism, and there have been attempts to construct alternatives that rely on the idea that to explain an event is to cite its real cause, where this cause need not be subsumed under any law. Since the demise of logical empiricism, or at least the waning of its influence, there has been a proliferation of theories about laws, causation and explanation, many of which differ radically from one another.
