 One weak emergentist approach locates the distinctness and distinctive efficacy of emergents in feature or process types, while maintaining that every token feature or process is identical with a token fundamental physical entity. This view in a sense “splits the difference” with the reductionist, and so is the most minimalist of the weak emergent positions. One advantage of the view is that it provides a basis for resisting Kim’s argument for causal overdetermination. Causation is a token-token relation. If token higher- and lower-level entities are identical, then there is but one token cause of a given effect, which seems to dismantle the challenge. At the same time, the type-distinctness of weakly emergent and base features provides a basis for claiming distinctive efficacy through “causal relevance” considerations. We may query the cause of a token effect through the prism of distinct effect types, and which type we select will determine which cause type is relevant to its explanation.
