Martin and Pfeifer (1986) claim "that the most typical characterizations of intentionality" proposed by philosophers are satisfied by physical dispositions. If that is correct, we must conclude either, as they and Mumford do, that the philosophers are wrong and intentionality is something else or, as I do, that intentionality is what the philosophers say it is, in which case it is the mark, not of the mental, but of the dispositional. To my contention that the intentionality of a disposition consists in its being directed towards its future manifestations Mumford objects that the notion of directedness is obscure and cannot in the light of Martin's (1994) argument be elucidated by reference to what would happen if the conditions for its manifestation are satisfied. But Martin's argument rests on the mistaken assumption that causal conditionals of which dispositional ascriptions are an instance are of the form 'If p then q'.

Place, U. T. (2000d). The two-factor theory of the mind-brain relation. Brain and Mind, 1, 29-43. doi:10.1023/A:1010087621727
The analysis of mental concepts suggests that the distinction between the mental and the nonmental is not ontologically fundamental, and that, whereas mental processes are one and the same things as the brain processes with which they are correlated, dispositional mental states depend causally on and are, thus, "distinct existences" from the states of the brain microstructure with which 'they' are correlated. It is argued that this difference in the relation between an entity and its composition/underlying structure applies across the board. All stuffs and processes are the same thing as is described by a description of their microstructure. In all cases where the manifestation of a disposition extends beyond the "skin" of the dispositional property bearer, dispositions invariably depend causally on the structure, usually the microstructure, of the bearer.
