R. W. Dyson – författare

Thomas Aquinas (1225-74) is a massive figure in the history of western thought and of the Catholic church. In this major addition to the Cambridge Texts series Robert Dyson (whose modern rendition of Augustine's City of God has already been widely acclaimed) has chosen texts by Aquinas that show his development of a Christian version of the philosophy of Aristotle, its contrast with the Augustinian thought that had coloured so much political thinking in the previous eight centuries, and St Thomas's views as to the purpose of government, constitutions, and the relations between secular and ecclesiastical power. Property, slavery, and usury are fully covered, as are St Thomas's celebrated and influential writings on law. The translations are extremely accessible and the whole is supported by all of the usual series features designed to assist the student reader, including brief biographies, notes for further reading and a concise critical introduction.

This is the first new rendition for a generation of The City of God, the first major intellectual achievement of Latin Christianity and one of the classic texts of Western civilisation. Robert Dyson has produced a complete, accurate, authoritative, and fluent translation of De civitate dei, edited together with full biographical notes, a concise introduction, bibliography, and chronology of Augustine's life. The result is one of the most important single contributions to the Cambridge Texts series yet published, of interest to students of ecclesiastical history, the history of political thought, theology, philosophy, and late antiquity.

R. W. DYSON There will be few readers of this book who are not aware of the contribution that polymers make to modern life. They are to be seen around the home, at work, in transport and in leisure pursuits. They take many forms which include plastic mouldings and extrusions, plastic film and sheet, plastic laminates (fibreglass and formica) rubber gloves, hoses, tyres and sealing rings, fibres for textiles and carpets and so on, cellular products for cushioning and thermal insulation, adhesives and coating materials such as paints and varnishes. The majority of these polymers are synthetic and are derived from oil products. The most important of these in terms of tonnage used are polymers based upon styrene, vinyl chloride, ethylene, propylene and butadiene among plastics and rubber materials, and nylons, polyethylenetere­ phthalate and polyacrylonitrile among fibres. The total amount of these polymers used each year runs into millions of tonnes. These polymers are sometimes known as commodity polymers because they are used for everyday artefacts. They are available in many grades and formats to meet a variety of applications and processing techniques. The and light stabilizers, properties can be adjusted by using additives such as heat plasticizers, and reinforcing materials. Often, grades are specially designed and formulated to meet particular requirements and, in a sense, these might be regarded as specialities. Much has been written about these materials elsewhere and they are not the concern of this book.
