What sort of difficulties are faced by Humean and dispositional accounts of causality? On the one hand, Humean accounts explain the relation of causality in terms of contiguity, temporal priority, constant conjunction, and contingency, denying any notion of modality in light of the fact that there is no experiential impression of necessity involved in causation. But this is not persuasive as it does not accord with ordinary intuitions. On the other hand, many dispositionalists interpret causality, not as a relation between objects or events, but as a relation between dispositional properties. Some go further and try to explain dispositional properties in terms of mutuality, contemporaneity, ubiquity, and holism. However, this sort of analysis is also counter-intuitive in a different dimension.
