 Causation is thus analysed in terms of spatiotemporal contiguity, temporal precedence, and regular connection. The causal relation is reduced to non-causal entities: the two particular facts about spatiotemporal contiguity and temporal precedence, and the general regularity. There is nothing more to causation according to HRT. In particular, causation does not involve a necessary connection, a productive relation, causal powers, or the like—not even to ground the regularities. This stance against metaphysically thick conceptions of causation is characteristic for the regularity theory (see, e.g., Dowe 2000: Ch. 2; Psillos 2009).
