This book is a collection of twelve essays devoted to Michael Boylan's important work in moral philosophy,A Just Society. The collection is thematically organized to mirror Boylan's own volume, so the first half explores fundamental issues of justification in ethics while the second half focuses on issues involving ethical discourse, social justice, and the moral foundations of public policy. In their critical and engaging essays, the authors challenge many of the original and controversial arguments developed and defended by Boylan in his book, and Boylan responds in a lengthy and philosophically rich reply. The book will appeal both to philosophers working on the cutting edge of moral and political theory and to public policy practitioners working to make society more just.
