Fredric Jameson, in The Political Unconscious, opposes the view that literary creation can take place in isolation from its political context. He asserts the priority of the political interpretation of literary texts, claiming it to be at the center of all reading and understanding, not just a supplement or auxiliary to other methods current today. Jameson supports his thesis by looking closely at the nature of interpretation. Our understanding, he says, is colored by the concepts and categories that we inherit from our culture's interpretive tradition and that we use to comprehend what we read. How then can the literature of other ages be understood by readers from a present that is culturally so different from the past? Marxism lies at the foundation of Jameson's answer, because it conceives of history as a single collective narrative that links past and present; Marxist literary criticism reveals the unity of that uninterrupted narrative. Jameson applies his interpretive theory to nineteenth- and twentieth-century texts, including the works of Balzac, Gissing, and Conrad. Throughout, he considers other interpretive approaches to the works he discusses, assessing the importance and limitations of methods as different as Lacanian psychoanalysis, semiotics, dialectical analysis, and allegorical readings. The book as a whole raises directly issues that have been only implicit in Jameson's earlier work, namely the relationship between dialectics and structuralism, and the tension between the German and the French aesthetic traditions. The Political Unconscious is a masterly introduction to both the method and the practice of Marxist criticism. Defining a mode of criticism and applying it successfully to individual works, it bridges the gap between theoretical speculation and textual analysis.

The use of lubricants began in ancient times and has developed into a major international business through the need to lubricate machines of increasing complexity. The impetus for lubricant development has arisen from need, so lubricating practice has preceded an understanding of the scientific principles. This is not surprising as the scientific basis of the technology is, by nature, highly complex and interdisciplinary. However, we believe that the understanding of lubricant phenomena will continue to be developed at a molecular level to meet future challenges. These challenges will include the control of emissions from internal combustion engines, the reduction of friction and wear in and continuing improvements to lubricant performance and machinery, life-time. More recently, there has been an increased understanding of the chemical aspects of lubrication, which has complemented the knowledge and understanding gained through studies dealing with physics and engineering. This book aims to bring together this chemical information and present it in a practical way. It is written by chemists who are authorities in the various specialisations within the lubricating industry, and is intended to be of interest to chemists who may already be working in the lubricating industry or in academia, and who are seeking a chemist's view of lubrication. It will also be of benefit to engineers and technologists familiar with the industry who require a more fundamental understanding of lubricants.
