The Non-Transitivity of Causation

There are clear cases in which causation is not transitive and this drops out of the analysis developed in which causation involves a certain kind of chance-raising involved after subtracting competitor processes. Attempts to explain away these cases to secure the transitivity of causation are a mistake. Alternative ways of capturing the non-transitivity of causation involve fixing the competitor processes in order to detect chance-raising dependencies between the target cause and effect. This alternative manoeuvre engenders problems. The non-transitivity of causation is better understood in the terms of my analysis rather than by appealing to the idea that causes are difference-makers (in a specified sense) or, in the kind of cases considered, switchers by interaction with a process.
