Academic freedom-the institutional autonomy of scientific, research and teaching institutions, and the freedom of individual scholars and researchers to pursue controversial research and publish controversial opinions-is a cornerstone of any free society. Today this freedom is under attack from the state in many parts of the world but it is also under question from within academe. Bitter disputes have erupted about whether liberal academic freedoms have degenerated into a form of coercive political correctness. Populist currents of political opinion are questioning the price a society pays for the freedom of its `experts' and professors. This volume summarizes the highlights of the discussions of international experts and political figures who examined the state of academic freedom world-wide at a gathering in the summer of 2017. Topics range widely, from the closing of universities in Turkey and the narrowing space for academic freedom in Hungary, China and Russia, to the controversies about free speech roiling American campuses. The book contains thoughtful historical analysis of the origins of the ideal of academic freedom; eloquent testimony from the front lines of the battle to defend the academy as a free space for controversial thought; as well as analysis of how university autonomy and self-government are endangered by hostile political forces around the world.
