"Physical Causation discusses in a systematic way an original, positive account of causation: the conserved quantities account of causal processes that Phil Down has been developing over the last ten years." "Dowe offers a account of causation based firmly in contemporary science. The book describes causal processes and interactions in terms of conserved quantities: a causal process is the world line of an object that 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 of time travel."--Jacket.
