In the last fifty years, many aspects of socialism have been rolled back around the world. Indeed, in the 1990s, following the collapse of communism in Central and Eastern Europe, it seemed as if classical liberal ideas had triumphed. But this did not happen by accident. The role of free-market think tanks was critical. This short video profiles Taming Leviathan: Waging the War of Ideas, a volume that draws on the experiences of thirteen authors involved in classical liberal think tanks in different parts of the world. The contributors identify the strategies that have proved successful in influencing the public policy and explain how they can be adapted to local circumstances. Indeed, though the ‘war of ideas’ has been hard fought, it has been only partially won. New threats to freedom have emerged, including environmentalism and big-government conservatism. In some countries the burden taxation and regulation has never been greater. Taming Leviathan is essential reading for anyone involved in the battle against resurgent collectivism.
