 Another line of argument for PIT similar to Searle’s aspectual shape argument is an argument from content determinacy. Graham, Horgan &amp; Tienson (2007) and Horgan &amp; Graham (2012) argue that it is difficult to see how unconscious neural activity, functional role, dispositions to behavior, and other possible physical bases of intentionality can yield the sorts of determinate contents we manifestly represent (see also Dennett 1987, Quine 1960: ch. 2, and Kripke 1982). For example, no causal, functional, or purely physical features of one’s brain or environment seem to make it the case that one is thinking about rabbits rather than undetached-rabbit-parts. A Martian looking down on Earth with complete knowledge of all Earthly physical facts could not tell whether we are representing rabbits or undetached rabbit parts. Thus, it appears that a physical-functional theory of intentionality will predict that one’s concept RABBIT is indeterminate between the two contents.
