  This is an empiricist account of language learning reminiscent of the account attributed by Wittgenstein to Augustine, and severely criticised by him. Apart from the superhuman inferential powers attributed to the child, the problem highlighted by Wittgenstein is that no amount of observation can show, for example, that the relevant correlation is between “cow” and cow-individuals, and not between “cow” and B’s cow-directed-actions, the universal cowhood, heifers rather than cows, etc. (cf. TSD 66d).
