In this latest collection of poems and verse-essays, Christopher Norris revisits many of the topics for which he is best known as a philosopher, literary theorist, and writer on music. Among them are the many-worlds metaphysics of Leibniz, the nature of subjective time-experience, the issue of poetic truth, the function of rhyme in poetry, the theory wars in literary studies, the augmented-fourth interval (or tritone), also known as the devil in music, and musical minimalism approached from a critical or cultural-diagnostic standpoint. There are also some shorter, more occasional pieces including an epithalamion (wedding-poem) for the poet's daughter, a semi-fictive double sestina about police infiltration of activist groups, a savagely bawdy polemic imagined as addressed by the ancient Greek satirist Archilochus to his ex-fiancee Neobule, and a number of shrewdly angled political poems with reference to events from the 1980s to the present. These pieces have the hallmark qualities of intellectual range, perceptive wit, and formal inventiveness that characterise Norris's verse-essays. They make a strong case for poetry as a vehicle for argument, dialogue, and open debate.
