Mendelovici (2018) also argues for Moderate PIT on the grounds of metaphysical sufficiency: The ingredients invoked by alternative theories of intentionality, such as tracking and functional role theories, are not metaphysically sufficient for intentionality. For instance, it is unclear why having internal states playing certain functional roles should result in those internal states representing a particular content, or any content at all. Likewise, while tracking relations relate us to items that may seem to be well-suited to playing the role of content, such as objects, properties, and states of affairs, it is mysterious how tracking such items could make them psychologically relevant to us. For instance, it is unclear how merely tracking such items can make them introspectively accessible, available to reason with, or in any sense “entertained”. (See also BonJour 1998 for similar worries with tracking and functional role theories.) In contrast, PIT’s central ingredient, phenomenal consciousness, is arguably metaphysically sufficient for intentionality. For instance, it is arguably inconceivable for there to be someone with a reddish phenomenal experience who does not thereby represent redness. If all this is right, then there is reason to think that phenomenal consciousness alone is metaphysically sufficient for intentionality, which supports Moderate PIT.
