J. D. Bernal's monumental work, Science in History, was the first full attempt to analyse the reciprocal relations of science and society throughout history, from the perfection of the flint hand-axe to the hydrogen bomb. In this remarkable study he illustrates the impetus given to (and the limitations placed upon) discovery and invention by pastoral, agricultural, feudal, capitalist, and socialist systems, and conversely the ways in which science has altered economic, social, and political beliefs and practices. This fourth and final volume discusses the social sciences, from early rituals and myths, through ancient and medieval conceptualisation of society, and finally on to Marxism, economics, anthropology, and these sciences' impact on twentieth-century perspectives. 'This stupendous work . . . is a magnificent synoptic view of the rise of science and its impact on society which leaves the reader awe-struck by Professor Bernal's encyclopaedic knowledge and historical sweep.'
