A cogent and clearly reasoned analysis of scientific influence which ranges from the historical past to the conjectural future and shows its direct intellectual effects as well as its effects on practical techniques and philosophical values. These essays, which are based on lectures originally given at Oxford, show how science has reacted against tradition and the often faulty assertions of the ancients; how through certain key inventions (the cotton gin, the telegraph, etc.) industrialization and centralization and integration has been achieved; scientific techniques in an oligarchy (any single power system) and the ways in which science favors tyranny as well as war--- and in a democracy; science and our values- ""It can diminish bad things""- poverty, long hours of labor, etc. and increase ""good things""- education, opportunity, etc. and finally the possibility of stability in a scientific society.... Less obstreperous than much that he has written, this is a straightforward examination for a thoughtful reading audience.
