Abstract
Theorizing about something we tend to conceive of it as objective and admitting, in principle, of a clear-cut distinction between what it is in its own right and what we believe about it. Obviously this tendency gets us into trouble if we theorize about the mental, and it is the tenet of this paper that the temptation to objectify the mental is the main source of our notorious difficulties with it. Evidence is presented from a variety of fields, from set theory, semantics and epistemology to doxastic logic.
