Of the three views mentioned above, Strong PIT asserts the strongest possible relationship between phenomenal intentionality and intentionality: it claims that phenomenal intentionality is the only kind of intentionality there is. Relatively few hold this view, but versions of it have been defended by Pitt (2004), Farkas (2008a), and Mendelovici (2010, 2018). The difficulty with this view, as we will see below, is that it is not clear that there are enough phenomenal states or phenomenal states of the right kind to constitute all intentional states. For example, it is not easy to see how standing beliefs like your belief that grass is green could be constituted by phenomenal states.
