What is the relationship between cause and effect? 3. How are causal claims to be assessed? This volume is a selective history of answers that have been given to the above three questions, augmented by occasional evaluative comments by the author. The first question is about the structure of the world. Answers given to this question assert that things in the world stand thus and so, and not otherwise. To ascribe “causation” to states of affairs is to make an ontological claim. For instance, one may claim that event e causes event e in a specific case or that all events 1 2 of type c cause events of type e. The second question is about theories that interpret causal related- ness. Some theories of causality take the relationship to be logical: c is a necessary condition of e, or c is a sufficient condition of e, or c is an INUS condition of e (c is an insufficient but necessary member of a set of conditions, which set is unnecessary but sufficient for e). Other theories take the relationship to be empirical: c and e are members of classes of events that display constant sequential conjunction, there is energy or momentum transfer between c and e, or there is exchange of a conserved quantity from c to e. The third question is about proper procedure in science and ev- eryday life. The usual procedure is to demonstrate that the claim in question satisfies the requirements of one or more theory of causality. In addition, one may support a claim by showing that it is consistent with established scientific laws and that it is superior to other possible claimants to causal status. I have sought to present theories of causality within a historical survey that emphasizes the interrelationship between these theories and developments in science. I hope that my analysis displays the strengths and the weaknesses of these theories in such a way as to contribute to our present understanding of causal relatedness. vii Theories of Causality Some disclaimers are in order. The subject matter of this study is physical causation, and the history of theories advanced to interpret it. Psychical states may cause, and be caused by, external events. However, mental causation is not a principal focus here. I have relied on present ideas about causal relatedness in the se- lection of subject matter for this volume. This reliance leads to some exclusions, despite the fact that the excluded theories were regarded as important at one time. In particular, I have little to say about ap- peals to God as cause of events, miraculous or otherwise. And I ignore the once influential preoccupations with causation by astral forces or alchemical forces. viii I Classical Sources: Theories of Causality Prior to 1900
