Originally published in 1970, the papers in this volume discuss the essential and defining characteristics of morality and moral issues and examine how moral views differ from political views, moral beliefs from religious beliefs, and moral judgements from aesthetic judgements. Some of the chapters discuss problems of method and shed light on the complex conditions which any successful definition of morality must satisfy. Taken collectively, these papers reflect he wide variety of approaches adopted by contemporary philosophers.

This book is a study of plasma waves which are observed in the earth's magnetosphere. The emphasis is on a thorough, but concise, treatment of the necessary theory and the use of this theory to understand the manifold varieties of waves which are observed by ground-based instruments and by satellites. We restrict our treatment to waves with wavelengths short compared with the spatial scales of the background plasma in the mag netosphere. By so doing we exclude large scale magnetohydrodynamic phenomena such as ULF pulsations in the Pc2-5 ranges. The field is an active one and we cannot hope to discuss every wave phenomenon ever observed in the magnetosphere We try instead to give a good treatment of phenomena which are well understood, and which illustrate as many different parts of the theory as possible. It is thus hoped to put the reader in a position to understand the current literature. The treatment is aimed at a beginning graduate student in the field but it is hoped that it will also be of use as a reference to established workers. A knowledge of electromagnetic theory and some elementary plasma physics is assumed. The mathematical background required in cludes a knowledge of vector calculus, linear algebra, and Fourier trans form theory encountered in standard undergraduate physics curricula. A reasonable acquaintance with the theory of functions of a complex vari able including contour integration and the residue theorem is assumed."

In the nineteenth century the Eastern Frontier of the Cape Colony was the stage on which a hundred years of conflict between Briton, Boer, and Xhosa was played out, fed by competition for land and mutual cultural incomprehension. The consequences of that conflict are still playing out in modern South Africa. Britain's motive in establishing the British settlement of 1820 was to set up a buffer on the border between the Xhosa on the east of the Great Fish River, and the Colony on the west. The motive of those who braved the journey was to find a better life than that offered by Britain after the Napoleonic wars. This is the story of some of them, including: Robert Hart - The first British settler. Soldier. Pioneering farmer. Patriarch. Edward Driver - Smuggler. Daring elephant hunter. Trader. Guide to General Sir Harry Smith. Always close to trouble but emerging unscathed. The Thackwrays - Pioneers, traders and explorers. Father and two sons each died violently, trying to make better lives for their families. Joseph Walker - One of a group of merchants and entrepreneurs who made their fortunes on the frontier. John Forbes Cumming - Missionary. A man combining deep religious conviction with romantic dreams and great courage. They became joined by family ties. Their stories include tales of murder, gunfights, war, massacre, and unrequited love, and are interwoven with the historical narrative. The material is extensively researched using a wide range of primary sources. The protagonists influenced and were influenced by those they encountered. This also the story of all those people - Xhosa kings and commoners, Boer farmers and adventurers, South Africans to-be with different languages and cultures. The book epitomizes Carlyle's observation: "History is the essence of innumerable biographies." It is a gripping account of the history of the Eastern Cape Frontier as experienced by some who lived there.
