 The themes that populate the texts above are wide and varied. Some harken back to Tractarian refrains, more appear to introduce later Wittgensteinian terms; a number of subjects make transitory appearances, never to return. Phenomenology, for one, is a constant Wittgensteinian concern, mostly for interpreters of all Wittgensteins who bicker over the very ascription of phenomenology to Wittgenstein’s thought, accompanied by their attempt to define Wittgenstein’s use of the term. But it is in the middle Wittgenstein that phenomenology makes a literal appearance, specifically in the “Phenomenology is Grammar” chapter of The Big Typescript. The questions then become whether phenomenology can be ascribed to the early Wittgenstein, whether it was really only adopted in the later Wittgenstein, and most relevant here – whether it can be identified as either vacating the scene in the middle Wittgenstein or, contrarily, there becoming terminologically and therefore significantly present. There is also the option that phenomenology appears exclusively in the middle Wittgenstein. These last options may then be seen as (at least partly) definitive of a middle period.
