Wittgenstein: Meaning and Mind. Volume 3 of an Analytical Commentary on the Philosophical Investigations by P. M. S. Hacker (review)

BOOK REVIEWS 161 Wittgenstein: Meaning and Mind. Volume 3 of an Analytical Commentary on the Philosophical lnvestigatwns. By P. M. S. HACKER. Oxford: Basil Blackwell, 1990. Pp. xxi + 575. In this third volume of his magisterial analytical commentary on Ludwig Wittgenstein's Philosophical lnvestigatwns, Professor P. M. S.

The present book begins with the generally-accepted first appearance of discussion of a private language at # 243 and runs through the discussion of conscious processes and criteria at# 427. In appreciation of the difficulty of the topic and the attention it has attracted, Hacker writes of " The tropical undergrowth of the great private language arguments," of how "the path is overgrown" and covered with dark distorting shadows, of how " the path through this terrain is shrouded in gloom," and its very direction difficult to discern (xv-xvi). Helpfully, however, he gives us a guide to his own path-finding volume. It consists of thirteen essays, each intended to stand independently of the rest, a fact which leads to a certain amount of repetition and overlap. " The same nodes often appear in different essays" (xvi), but in relation to different topics. Correlated with each essay is an exegesis of the pertinent stretches of Philosophical lnvestig
