Guy Debord was the founder of the Situationist International, the notorious avant-garde group that helped trigger the May 1968 revolt in France, which brought the entire country to a standstill for several weeks. His book The Society of the Spectacle, originally published in Paris in 1967, has been translated into more than twenty other languages and is arguably the most important radical work of the twentieth century. Ken Knabb's meticulous new translation is the first edition in any language to include extensive annotations, clarifying the historical allusions and revealing the sources of Debord's quotations and 'detournements.' Contrary to popular misconceptions, Debord's book is neither an ivory tower 'philosophical' discourse nor a mere expression of 'protest.' This makes the book more of a challenge, but it is also why it remains so pertinent more than half a century after its original publication, while countless other social theories and intellectual fads have come and gone. It has, in fact, become even more pertinent than ever, because the spectacle has become more all-pervading and glaringly obvious than ever. As Debord noted in his follow-up work, Comments on the Society of the Spectacle (1988), 'spectacular domination has succeeded in raising an entire generation moulded to its laws.' Debord's book remains the best guidebook to understanding that Mold and breaking it.
