Book excerpt: In this volume, fifteen scholars from the United States, Spain, Puerto Rico, and Colombia discuss the social implications of new technologies. Their essays address the cultural worlds that crystallize around technologies, the challenges to democracy that they pose, and the responsibility of modern technology for forcing a public response to new social and moral issues. Three themes define the three sections into which the volume is divided: "New Worlds," "New Technologies," and "New Issues." The essays in the section "New Worlds" range from optimism that new technologies will produce a better world than that of 1992, through a nonjudgmental discussion of the transformation of our "lifeworld" that new technologies are effecting, to deep concern for the viability of the world that modern technology has already created. In "New Technologies," the focus is on political responses to modern technologies. The authors in this section see the challenge to understanding and controlling our technological world in reshaping existing relations of social power and authority, and in creating new institutions more adequate to the sociopolitical realities of the process of technological innovation. While the contributors in the first two sections of the volume argue that broad changes in values and institutions are preconditions of a more beneficent relationship among people, nature, and technology, those in the section "New Issues" adopt narrower, more specific, viewpoints. Their essays address the political values underlying the Deep Ecology movement, the ethics of military technologies, the capacity of democratic institutions for a public role in setting technology policies, and science and technology literacy mechanisms. Collectively, these essays reflect the growing international concern with the role played by technological innovation in a rapidly changing world, and they point toward the formulation of concrete political platforms for informed social responses to the innovation process.
