Abstract

A number of theories of dispositions to date have presupposed that dispositions are all causal:  when X is disposed to PHI in circumstances C, it is because of a potential causal connection between C and X’s PHIing. Other intimate connections between dispositions and causation have been argued for: that the relation between dispositions and their categorical bases is to be understood in causal terms, for example, or even that we can explain causation in dispositional terms. These theories of dispositions are all threatened by previously underappreciated cases of noncausal dispositions: cases where an X is disposed to PHI in C, but not because of potential causal connections between the manifestation conditions of dispositions and the manifestations themselves. This paper argues that there are noncausal dispositions of a number of different varieties, explains what trouble this causes many standard theories of dispositions, and discusses what lessons can be learned from these cases for the nature of dispositions. Some of the cases discussed will also cast doubt on the idea that all dispositions ground truths about potentiality or possibility.
