 The most immediately plausible purported example of phenomenal intentionality is the content of perceptual experience. If perceptual experience is a genuine example of phenomenally determined intentionality, but also the only example, then the argument from phenomenal intentionality would show the existence of narrow contents of perceptual states, but would be silent on whether other mental states such as beliefs and desires have narrow contents. However, some defenders of phenomenal intentionality (e.g. Horgan, Tienson and Graham 2004 and several of the contributors to Bayne and Montague 2011) would go further, arguing that there are distinctive phenomenologies of agency and of propositional attitudes including beliefs and desires; that the phenomenal properties of these mental states also constitutively determine intentional properties; and moreover that all intentionality either is identical with, or is derived from, phenomenal intentionality. If these bolder theses are correct, then the argument from phenomenal intentionality would give reason to think that all of the propositional attitudes have narrow contents, and that their wide contents, if any, are derived from these narrow contents.
