In the last six or seven years, aphantasia has received attention from media outlets, television shows, and social networks. This alleged condition, however, has hardly been discussed in the philosophy of mind. In this paper, I assess some of the research conducted in cognitive science and provide, for the first time in the literature, a comprehensive assessment of possible explanations for aphantasia. Specifically, the hypotheses I submit for consideration ascribe the reports of absence of visual imagery to (i) a discrepancy at the level of concepts, (ii) a failure of attentional mechanisms that modulate introspection, (iii) a lack of personal-level access to sub-personal imagistic representations, and (iv) an absence of sub-personal imagistic representations. I conclude that hypotheses (i) and (ii) can be rejected while hypotheses (iii) and (iv) can be accepted as defensible candidates for explaining aphantasia, although the latter is better suited to account for the available evidence in both comparative and absolute terms. Finally, I present some educated guesses and empirical research that could shed further light on the study of this condition.
