Clarence Thomas is one of the most vilified public figures of our day. To date, however, his legal philosophy has received only cursory treatment. First Principles provides a portrait of Thomas based not on the justice's caricatured reputation, but on his judicial opinions and votes, his scholarly writings, and his public speeches. The paperback edition includes a provocative new Afterword by the author bringing the book up to date by assessing Justice Thomas's performance, and the reaction to his decisions, during the last five years.
