Agency and Deontic Logic represents a major advance in the field, developing fresh ideas for thinking about longstanding internal problems and making significant connections with external areas of research, most notably decision theory and utilitarian ethical theory. Although the book is technically sophisticated, the discussion is exceptionally clear and readable and benefits greatly from numerous examples and diagrams. Agency and Deontic Logic should interest an audience that includes logicians, computer scientists, and those working in decision theory, game theory, and ethics, as well as applications of these disciplines.

These essays on the history of political argument in the United States constitute both a scholarly contribution and a distinctive political intervention in contemporary discussions of liberalism. Kloppenberg's liberalism is much closer to European social democracy than to what is attacked or defended in most of today's disputes about the 'l-word.' Kloppenberg is one of the best historians now working on any aspect of the intellectual history of the United States.

Everyone interested in the past, present, and potential of liberalism should read this passionate book. It sparkles.
