Giving grounds, however, justifying the evidence, comes to an end; but the end is not certain propositions striking us immediately as true, i.e. it is not a kind of seeing on our part; it is our acting, which lies at the bottom of the language-game.
Ludwig Wittgenstein, On Certainty, §204
The origin of the primitive form of language game is a reaction; only from this can more complicated forms develop. Language – I want to say – is a refinement, ‘in the beginning was the deed’.
Ludwig Wittgenstein, Culture and Value, p. 31
