ABSTRACT
There can be no doubt that there is a close connection in the Philosophical Investigations between being human, behaving in human ways, and mastering a language.1 Wittgenstein suggests, in many ways throughout the Investigations, that there is a range of typically human behaviour which is involved both in learning and using a natural language. And one might conjecture that both the range of behaviour and the linguistic capacity are manifestations of one and the same deep-rooted human nature. Mastering some natural language may be due to a unique competence for mastering language, and behaving in human ways may depend on sharing an essential human nature.
