We normally assume that there’s just one conscious individual per animal. Some question this, suggesting that there may be nonhuman taxonomic groups whose normal, adult members house more than one conscious subject. Call this the multitudes view (“MV)”. Our aim is methodological: we hope to understand how we might assess whether MV is true. To that end, we distinguish two strategies for counting conscious subjects: the duplication strategy and the mind-first strategy. We use human split-brain patients and octopuses to illustrate (...) the prospects and limitations of each approach, as some have argued that both sets of individuals contain multitudes. We’ll contend that while the duplication strategy is applicable to split-brain patients, it isn’t apt for octopuses. The mind-first strategy fairs better here, but there’s a catch: it requires, in a way the duplication strategy does not, numerous contentious assumptions about the nature of mentality, the individuation of minds, and consciousness to simply get off the ground. These difficulties clarify just what it would take to establish MV. (shrink)

Brentano’s suggestion that intentionality is the mark of the mental is typically spelled out in terms of the thesis that all and only mental states are intentional. An influential objection is that intentionality is not necessary for mentality. What about the idea that only mental states are intentional? In his 2008 paper published in Analysis, Nes shows that on a popular characterization of intentionality, notably defended by Crane, some non-mental states come out as intentional. Crane replies that the concept of (...) representation solves the problem. In this paper, I argue that no representational account of intentionality meets Nes’s challenge. After distinguishing between two notions of representation, I contend that there are two versions of Crane’s representational account, but neither of them is able to solve the problem posed by Nes.
