The Significance of Learning in Wittgensteins Later Philosophy

Abstract

‘When a child learns this ....’ ‘What is “learning a rule”?— This.’ Anyone familiar with Wittgenstein’s later philosophy recognizes these phrases as wholly typical of that philosophy. The appeals to the way in which a child learns, to learning in general, and to the italicized use of the indexical – all are familiar themes. In the Philosophical Investigations Wittgenstein develops his position on three crucial philosophical issues by beginning with the way in which a child learns. First, his critique of referential theories of meaning: ‘An important part of the training will consist in the teacher’s pointing to the objects, directing the child’s attention to them, and at the same time uttering a word’ (PI §6). Second, his attack on essentialist theories of understanding: ‘How does [the pupil] get to understand this notation? – First of all the series of numbers will be written down for him and he will be required to copy them .... And here there is a normal and an abnormal learner’s reaction’ (PI §143). And finally, his attack on the Cartesian model of consciousness: ‘A child has hurt himself and he cries; and then adults talk to him and teach him exclamations and, later, sentences’ (PI §244). These three critiques are the cornerstones for his later philosophy, and at the beginning of each he appeals to how children learn. Moreover, Wittgen-stein’s subsequent writings show an increase in the explicit appeal to learning and to a child’s learning. In On Certainty, Wittgenstein’s final work, virtually every page involves appeal to learning. In spite of this, most commentators treat the appeal as incidental.
