Philosophizing the indefensible asks what distinctive contributions political philosophers might make when reflecting on blatant moral failures in public policy - the kinds of failures that philosophers usually dismiss as theoretically un-interesting, even if practically important. This book argues that political philosophers can and should craft “strategic” arguments for public policy reforms, showing how morally urgent reforms can be grounded, for the sake of discussion, even in problematic premises associated with their opponents. The book starts by developing the general contours of this approach - defending its general moral value in a democratic society, and examining how far one might go in strategically deploying dubious or even repugnant premises in debating public affairs. The book then applies strategic theorizing to a set of diverse policy issues. These range from the abortion debate and financial regulation in the United States, through controversies surrounding the participation of Arab parties in Israel's political process, to global issues, such as commercial ties with oil-rich dictatorships, and the bearing of such ties on global climate change.
