This collection of essays addresses the question of lucidity as a thematic in literature and film but also as a quality of both expression and insight in literary criticism and critical thought more generally. The essays offer treatments of lucidity in itself and in relation to its opposites, forms of obscurity and darkness. They offer attention to problems of philosophical thought and reason, to questions of literary and poetic form, and of photographic and filmic contemplation. Ranging from engagements with early modern writing through to more recent material the contributions focus in particular on nineteenth- and twentieth-century French prose and poetry, the field which has been the predominant focus of Alison Finch’s critical writing. They are written as tributes to the distinctively lucid insights of her work and to the breadth and clarity of its intellectual engagement.
