Abstract

Brenner labels his book a “companion”. It provides a workbook or roadmap that can used to guide one’s reading of Philosophical Investigations. Its first half follows the progression of Wittgenstein’s text. Rather than providing a traditional commentary, Brenner proceeds by testing paraphrases of key sections, juxtaposing well-traveled with less familiar passages, and constructing ongoing dialogues with various Wittgensteinian interlocutors. The book’s second half presents interpretative essays on Wittgenstein’s treatment of the mental, the grammar of color and number talk, and the idea of “theology as grammar.” Brenner skillfully navigates the difficult paths of Wittgenstein’s criticisms of traditional philosophy. While emphasizing that Wittgenstein’s philosophical activity systematically opposes itself to reductionism and to attempts to think beyond the limits of thought and language, he avoids the pitfalls of ascribing to Wittgenstein a dogmatic standard by which to deem traditional metaphysical theorizing nonsensical. He appreciates that to understand how Wittgenstein puts the nature of philosophy in question, we must work through the ways his methods force our attention onto particulars and dampen our “craving for generality.” Wittgenstein tries to impress on us the need to reexamine the details of our lives as language users, and to lead us to the “real discovery” that affords a “complete clarity” on which “the philosophical problems should completely disappear”. In this call for attentiveness, Brenner finds the essential spirit of Wittgenstein’s thinking. Here “the true value of philosophy lies in this clarificatory activity”, and “life ceases to seem essentially problematic”.
