In these seventeen essays, distinguished senior scholars discuss the conceptual issues surrounding the idea of freedom of inquiry and scrutinize a variety of obstacles to such inquiry that they have encountered in their personal and professional experience. Their discussion of threats to freedom traverses a wide disciplinary and institutional, political and economic range covering specific restrictions linked to speech codes, the interests of donors, institutional review board licensing, political pressure groups, and government policy as well as phenomena of high generality such as intellectual orthodoxy in which coercion is barely visible and often self-imposed.-- Publisher
