 However, as Husserl was well aware, the species-theory of content faces at least one serious objection. This objection concerns utterances that are “essentially occasional”, i.e., systematically context-sensitive, expressions like “I am here now” and the ‘indexical’ experiences they give voice to. If the intentional content of an indexical experience is to serve as a (sub-)propositional content, it must uniquely determine the object (if any) that the respective experience refers to. That is to say: if two indexical experiences display the same intentional content, they must refer to the same object (if any). It seems, though, that the moments of matter of two such experiences can instantiate the same ideal matter—the same type of (particular) content—whilst representing different objects. If you and I both think “I am here”, our respective thoughts share the same type of content, or so it would seem, but they represent different states of affairs. In order to accommodate this observation, Husserl draws a distinction between, on the one hand, the “general meaning function” of an utterance (which corresponds to what David Kaplan calls “character”, roughly: the linguistic meaning of the expression used) and, on the other hand, the “respective meaning” (i.e., the propositional or sub-propositional content expressed in the relevant context of utterance). However, it is doubtful whether this distinction really helps Husserl overcome the difficulty the phenomenon of context-sensitivity poses for his species-theory of content. If intentional contents are ideal matters in the sense of types of particular matters, and if this kind of type may remain constant while the intentional object and hence the (sub-)propositional content differs, then surely intentional contents thus conceived cannot always function as (sub-)propositional contents, as Husserl’s theory would have it. Rather, there must be another intentional content involved, namely the “respective meaning”, which serves as the (sub-)propositional content of the indexical experience. And this content does not appear to be an ideal species. (It may be argued, however, that even (sub-)propositional contents of indexical utterances can be instantiated multiply in thought and speech, thus qualifying as ideal species after all. But the crucial question is whether this holds true in complete generality: consider the above example “I am here now”.)
