   As one reads these lines, numerous questions arise: what does Brentano mean when he says that the object towards which the mind directs itself ‘is not to be understood as meaning a thing’? What can it be for a phenomenon (mental or otherwise) to exhibit ‘the intentional inexistence of an object’? What is it for a phenomenon to ‘include something as object within itself’?  Do ‘reference to a content’ and ‘direction toward an object’ express two distinct ideas? Or are they two distinct ways of expressing one and the same idea? If intentionality can relate a mind to something that either does not exist or exists wholly within the mind, what sort of relation can it be?
