The four essays that make up this volume are based upon and expand the lectures Ricoeur delivered at Texas Christian University, 27-30 November 1973, as their Centennial Lectures. They may be read as separate essays, but they may also be read as step by step approximations of a solution to a single problem, that of understanding language at the level of such productions as poems, narratives and essays, whether literary or philosophical. In other words, the central problem at stake in these four essays is that of works; in particular, that of language as a work.
