Intentionality in the Tractatus

In the Tractatus, Wittgenstein seems to appeal to the idea that thoughts manage to explain how sentences, primarily elementary sentences, can be such that their subsentential elements refer to objects. In this respect, he seems indeed to appeal to the claim that thoughts, qua endowed with not only original, but also intrinsic, intentionality, lend this intentionality to names, by transforming them into names-of’, i.e., symbols endowed with intrinsic intentionality as well. Such a claim, however, entails that there must be necessary superfacts (as he implicitly meant them in the Investigations). Since according to the Tractatus’ ontology there cannot be necessary facts in the world, but at most only in its logical scaffolding, the most likely chance is that such facts are facts for the limit of the world, i.e., the metaphysical subject. Curiously enough, in his later critique, in the Investigations, of mentalist semantics, Wittgenstein fails to appeal to this claim, which can block the infinite regress that he there changes the mentalist position with. Since in the Investigations necessary facts seem to be allowed, this failure is even more striking.
