The aim of this paper is to present the principles of intersubjectivity as a second-person relational account of mind, set against individualist first- and third-person accounts of the sharing of mental representations. I will set out a summary of these positions and defend the claim that understanding proto-conversations as “expressive communications” allows one to understand them as genuine communications, as in, mutually manifest communications that entail intersubjectivity. To support this interpretation, I will propose a novel explanation of expression, understood as (...) constitutive of the mental state. (shrink)
