As we previously saw (in § 5.6), the Tractarian states of affairs and facts, based on objects, are what is thinkable (intelligible) and what makes language possible. It is crucial to bear in mind that Wittgenstein implicitly distinguishes the Tractarian ontology from metaphysics (see § 6.10). The latter is valid so far as it holds for this, real world; while Wittgenstein’s “ontology” refers to all possible worlds and thus comports with human language, in fact, with everything that is thinkable or intelligible. Furthermore, Tractarian ontology, which is the flip side (the doppelganger) of its concept-script, demonstrates how objects of thinking and language go together. Moreover, it was developed following the principle of immediacy (see § 11.4). Its elements are connected without mediators—they inhere face-on-face against one another.
