'Lacey's book must be considered a major contribution and should be of interest to all philosophers of science and others interested in the role of values in supposed rational thought.' - Stephen Mumford, Mind'Lacey's arguments are readily accessible and do not require a specialist's knowledge - the book can easily serve as an introduction to the topical and controversial question of the role of values in scientific inquiry as well as challenging taken-for-granted positions of specialists.' - James Sauer, Research in Philosophy and Technology'Adds richness to the terms of the debate and intriguing philosophical framework for the problems that arise ... This work will raise important questions for anyone who has wondered, not whether science currently is value-free, but what such an ideal would be and whether the idea is defensible.' - Heather Douglas, Philosophy of Science
