Between 1907 and 1911, Ferdinand de Saussure gave three series of lectures on the topic of general linguistics. After his death, these lecture notes were gathered together by his students and published as the Course in General Linguistics. And in the past one hundred years, there has been no more influential and divisive reading of Saussure than that of Jacques Derrida. This book is an examination of Derrida's philosophical reconstruction of Saussurean linguistics, of the paradigm shift from structuralism to post-structuralism, and of the consequences that continue to resonate in every field of the humanities today. Despite the importance of Derrida's critique of Saussure for cultural studies, philosophy, linguistics and literary theory, no comprehensive analysis has before been written. The magnitude of the task undertaken here makes this book an invaluable resource for those wishing to interrogate the encounter beyond appearances or received wisdom.
