Intentional Objects as World Lines
Elizabeth Anscombe took there to be three salient features of intentional objects: indeterminacy, sensitivity to the way in which they are described, and possible non-existence [1, pp. 159, 161, 171]. Relatedly, Tim Crane speaks of accuracy, aspect, and absence as features of intentional states [18, pp. 455–6]. In Edmund Husserl’s theory of intentional relations, these or similar features have been termed indeterminacy of characterization, conception-dependence, and existence-independence of intentional relations; cf. [113, pp. 11–7].
