Persistence theories of causation – such as transference theory, conserved-quantity theory, and Douglas Ehring's theory – attempt to analyzecausation in terms of some persisting entityconnecting cause and effect. While mostpersistence accounts are intended as empiricaltheories, this article develops a persistenceanalysis of the concept of causation. The basic idea is that the central concept ofdirect causation can be analyzed in terms ofproperty acquisition. The analysis cohereswith our ordinary causal judgments andprovides a straightforward explanation of thedirection of causation. It also explains whybackwards causation is conceptually problematic.

Max Kistler’s first book, based on his Paris Ph.D. thesis, is an elaborate defence of a transference theory of causation. Such a theory conceives of causality as the transfer of a conserved quantity. A transference theory of causation is thus one form that a regularity account of causation, as opposed to a counterfactual account, might take. Kistler’s original contribution consists (a) in the way in which he develops an account of causation based on transference and (b) in relating a theory of causation to a specific view of natural laws. Kistler first considers what a relation of causation is and thereby contrasts the transference theory with other explanations (Ch. 1). He then develops a view of natural laws (Ch. 2) and combines this view with his transference theory of causation (Chs. 3 & 4). The second part of the book focuses on causally efficacious properties. Kistler employs the notion of properties that are responsable for a relation of causation. The function of such properties in laws of causation is examined (Chs. 5 & 6). The last chapter discusses examples that are to show how this theory of causation works (Ch. 7). Kistler argues for a realistic view: there is causation in the world independently of whether and how people conceptualize causal relations. The relata of a causal relation are events. An event is the content of a continuous space–time region (which may be as small as being pointlike) (18, 64–68). Events are in space–time what objects are in space (196): An object has spatial parts, whereas an event has spatio–temporal parts. To give an example, a volcano has spatial parts such as a top, whereas an eruption of a volcano can be gentle and limited to its northern side first and then become violent and extending to all sides. There is a relation of causation between two events if and only if at least one conserved quantity is transferred between them (39–40, 100). That is to say: an event x has a certain value of a physical quantity, and that individual value is transferred to another event y..

In this paper I examine Salmon's response to two counterexamples to his conserved quantity (CQ) theory of causation. The first counterexample that I examine involves a time‐wise gerrymandered world line of a series of patches of wall that is absorbing energy as a result of being illuminated in an astrodome. Salmon says that since the gerrymandered world line does not fulfill his “no‐interaction requirement,” his CQ theory does not suffer from the counterexample. But I will argue that his response fails both at a theoretical level and at a practical level. In so doing I point out a problem for CQ theorists' definition of a causal interaction. The second counterexample is concerned with a time‐wise gerrymandered world line of a series of patches that are in shadow, in Hitchcock's well‐known example. Salmon's response is based on a principle that Salmon thinks is derivable from the concept of a conserved quantity. However, I argue that the principle has a counterexample.

The idea that causation can be reduced to transmission of an amount of some conserved quantity between events is spelled out and defended against important objections. Transmission is understood as a symmetrical relation of copresence in two distinct events. The actual asymmetry of causality has its origin in the asymmetrical character of certain irreversible physical processes and then spreads through the causal net. This conception is compatible with the possibility of backwards causation and with a causal theory of time. Genidentity, the persistence of concrete objects, can be given an explanation in causal terms. The transmission theory is shown to escape difficulties faced by two important alternative theories of causation: Salmon's (1984) Mark Transmission Theory and Dowe's (1992a) Conserved Quantities Theory.

The conserved quantities theory of causation (CQTC) attempts to use physics as the basis for an account of causation. However, a closer examination of the physics involved in CQTC reveals several critical failures. Some of the conserved quantities in physics cannot be used to distinguish causal interactions. Other conserved quantities cannot always be the properties of fields or particles. Finally, CQCT does not account for causal interactions that are static.

This paper discusses several distinct process theories of causality offered in recent years by Phil Dowe and me. It addresses problems concerning the explication of causal process, causal interaction, and causal transmission, whether given in terms of transmission of marks, transmission of invariant or conserved quantities, or mere possession of conserved quantities. Renouncing the mark-transmission and invariant quantity criteria, I accept a conserved quantity theory similar to Dowe's--differing basically with respect to causal transmission. This paper also responds to several fundamental constructive criticisms contained in Christopher Hitchcock's discussion of both the mark-transmission and the conserved quantity theories.

In this paper I show how the conserved quantity theory, or more generally the process theory of Wesley Salmon and myself, provides a sufficient condition in an analysis of causation. To do so I will show how it handles the problem of alleged 'misconnections'. I show what the conserved quantity theory says about such cases, and why intuitions are not to be taken as sacrosanct.

This is a clear and original account of causation based firmly in contemporary science. Dowe discusses in a systematic way an original, positive account of causation: the conserved quantities account of causal processes which he has been developing over the last ten years. The book describes causal processes and interactions in terms of conserved quantities: a causal process is the worldline of an object which possesses a conserved quantity, and a causal interaction involves the exchange of conserved quantities. Further, things that are properly called cause and effect are appropriately connected by a set of causal processes and interactions. The distinction between cause and effect is explained in terms of a new version of the fork theory: the direction of a certain kind of ordered pattern of events in the world. This particular version has the virtue that it allows for the possibility of backwards causation, and therefore time travel.

I defend the conserved quantity theory of causation against two objections: firstly, that to tie the notion of “cause” to conservation laws is impossible, circular or metaphysically counterintuitive; and secondly, that the conserved quantity theory entails an undesired notion of identity through time. My defence makes use of an important meta-philosophical distinction between empirical analysis and conceptual analysis. My claim is that the conserved quantity theory of causation must be understood primarily as an empirical, not a conceptual, analysis of causation.

This paper examines the Transference Theory of causation, developed originally by Aronson (1971) and Fair (1979). Three difficulties for that theory are presented: firstly, problems associated with the direction of transference and causal asymmetry; secondly, the case of persistence as causation, for example where a body's own inertia is the cause of its motion; and thirdly the problematic notion of identity through time of physical quantities such as energy or momentum. Finally, the theory is compared with the Conserved Quantity Theory (Dowe 1992c), and it is shown that that account embodies the modifications that the transference theory needs to adopt.
