 A philosophical history would therefore do better to focus on the history of the problem of intentionality: the difficulty, that is, of providing a philosophically adequate account of the nature of intentionality in light of its various peculiarities, whatever terms may have been used to express it. Such an approach not only allows room for different theories of intentionality, but also divergent conceptions, as well as attempts to dissolve the problem, either by dismissing the phenomenon entirely or by denying that there is any genuine difficulty involved. A history of intentionality that did not include a Parmenides or a Quine would not be very informative, especially if we are trying to understand the difficulty and what is at stake.
