Abstract

Starting from an anecdote reported by Ernst Mach in the Analysis of Sensations, the author shows how the distinction between intentionality de re and intentionality de se can contribute to solving the individuation problem, at least for those individuals who are capable of self-referentiality. Intentionality is expressed linguistically in the form of the oratio obliqua, in the context of which the subordinate can be false even when the whole is true. The analysis of the conditions of falsity of the subordinate tells us that this can be false either because the predicate does not fit to the subject or by a failure of reference, conceived according to the descriptive theory of reference. The intentionality de se is peculiar precisely by the fact that in this case the reference cannot fail and uniquely individuates the haecceitas of the intentional subject.
