Absence Causation for Causal Dispositionalists

Several theories of causation reject causation of or by absences. They thereby clash with much of what we think and say about what causes what. This paper examines a way in which one kind of theory, causal dispositionalism, can be modified so as to accept absence causation, while still retaining a fundamental commitment of dispositionalism. The proposal adopts parts of a strategy described by David Lewis. The paper concludes with a brief discussion of the problem of the proliferation of causes.
