This account of the development of the Supreme Court's modern civil liberties and rights jurisprudence argues that the courts' supposed "new concern" for "personal freedoms" (after the New Deal) actually developed as the outgrowth of a sequence of highly particular progressive-reformist ideological currents that formed the modern American state. The book's theoretically-informed account of key paths of constitutional development thus weaves American political thought, American political development, and constitutional law together.
