Kai Nielsen is the author of more than a dozen books and over five hundred articles, and he has lectured on four continents over a long, fruitful, and influential career. He has made his mark especially in moral theory, social and political philosophy, the philosophy of religion, and metaphilosophy. In all these fields, he has consistently both advocated and exemplified the intellectual virtues of courage, clarity, candor, and reason. In this book, a group of distinguished colleagues and friends honor Nielsen's career with essays bearing on issues of abiding importance to him over his more than thirty years of philosophical activity. The resulting volume testifies both to the continuing value of Nielsen's work and to the liveliness and relevance of contemporary philosophy in these fields. - Publisher.
