This book traces the linguistic turns in the history of modern philosophy and the development of the philosophy of language from Locke to Wittgenstein. It examines the contributions of canonical figures such as Leibniz, Mill, Frege, Russell, Wittgenstein, Austin, Quine, and Davidson, as well as those of Condillac, Humboldt, Chomsky, and Derrida. Michael Losonsky argues that the philosophy of language begins with Locke's Essay Concerning Human Understanding and demonstrates how the history of the philosophy of language in the modern period is marked by a split between formal and pragmatic perspectives on language, which modern philosophy has not been able to integrate.
