In this short interview John Blundell talks about his paper Waging the War of Ideas, examining how wars of ideas can be waged, using his extensive experience of classical liberal think tanks. John Blundell begins his stimulating collection of published essays, reviews and introductions by showing how the founders of the IEA successfully fought the conventional planning wisdom of the 1960s and 1970s, providing the ideas which, by the 1980s and 1990s, had brought about increased freedom and a revival in the use of markets. He draws lessons from those days and then surveys the contemporary scene, showing how the anti-liberal ideas emerging now are different from those which prevailed in the early years of the IEA. As well as giving a valuable view of the IEAs development in the past, these essays also offer advice on how to continue winning in the new circumstances of the present.
