This study goes to the heart of ethics and politics. Strongly argued and lucidly written, the book makes a crucial distinction between two forms of democracy. The author defends constitutional democracy as potentially supportive of the ethical life, while he criticizes the plebiscitary form of democracyas undermiining man's moral nature. The book includes an extensive interpretation and refutation of the ideas of Jean-Jacques Rousseau and offers a new perspective on the American Constitution and the relationship between moral community and self-interest. This edition includes an important new section on the common good and the state of Western democracy.
