Taking Wittgenstein at his Word: A Textual Study (review)

This is an excellent book, which should be read widely. It is a short, lucid, and accessible introduction to Wittgenstein’s later philosophy, written by a leading expert. It is the ideal sequel to Saul Kripke’s Wittgenstein on Rules and Private Language on a short list of required readings for a course on Wittgenstein. Part 1 concerns rule following and the conceivability of a private language, while part 2 discusses three topics in his philosophy of mathematics: the status of mathematical expressions, Wittgenstein’s treatment of Cantor on transfinite cardinals, and his approach to logical consistency. There is very little discussion of the secondary literature on any of these topics. Instead, apart from a few prefatory methodological passages, almost all of the book is devoted to extensive quotations from Wittgenstein’s writing and to close reading of what he says there.

Fogelin’s chief aim, to take Wittgenstein at his word, is in a sense a very modest one. Wittgenstein insisted throughout his career that he was not presenting philosophical theses, and that philosophy should not be a matter of defending theses. Indeed, Fogelin explicitly acknowledges that in taking Wittgenstein at his word, he is not presenting “a novel—hitherto unrecognized—way of understanding Wittgenstein’s later philosophy” (xii–xiii). Nevertheless, most interpreters have read Wittgenstein as failing to follow his own methodological precepts, and their interpretations have focused on the theses that they attribute to him. Instead, Fogelin lets “Wittgenstein speak for himself” (xi), not only quoting at length from his writings, but also from Wittgenstein’s “self-commentaries” (xi), passages where Wittgenstein helps us appreciate the philosophical significance he assigns to his words. Crucially, these quotations are held together by a close reading that provides a lucid and perceptive statement of what Wittgenstein is saying there and why, highlighting the intimate connection between Wittgenstein’s philosophical methods and his treatment of key topics in the philosophy of language and mathematics.

A leading theme in Fogelin’s book is what he calls Wittgenstein’s “defactoist” approach to rule following. While he does not define this neologism, he does say that it involves “the rejection of appeals to rational processes where philosophers typically have attempted to find or supply them” (41). Furthermore, Fogelin connects it with the central role Wittgenstein gives to natural responses and training, the fact that the kind of training a creature can undergo depends on its natural or instinctive responses and Wittgenstein’s “rejection of the idea that training is merely an external device intended to induce in the trainee a grasp of the correctness, the legitimacy, of what he has been trained to do” (35–36).

Although Fogelin never explicitly addresses the crucial question of which texts to draw on in taking Wittgenstein “at his word,” in practice he makes use of a wide range of publications from every stage of Wittgenstein’s career. The Tractatus, written during the First World War, is treated as belonging to an earlier stage of his thought, and some similarities to and differences from his later work are discussed. No such distinctions are drawn between material written in the early 1930s, editors’ reconstruction of lecture notes from the early 1930s and late 1930s, passages from the Philosophical Investigations, assembled in the mid-1940s, the different parts of the Remarks on the Foundations of Mathematics, from the mid-1930s to early 1940s, and selections from On Certainty, dating from the late 1940s and early 1950s. While Fogelin acknowledges that there was some development in Wittgenstein’s views during these years, he puts great weight on passages taken from manuscripts and student lecture notes from the 1930s. For instance, in his crucial opening chapter on rule following, he relies heavily on the words with which Wittgenstein first formulated his paradox of interpretation in the early 1930s (20–21) and on his statement of the connection between meaning and rules in his 1932 lectures (17). While these passages are attractive precisely because they...
