Détournement is the opposite of quotation, of appealing to a theoretical authority that is inevitably tainted by the very fact that it has become a quotation — a fragment torn from its own context and development, and ultimately from the general framework of its period and from the particular option (appropriate or erroneous) that it represented within that framework. Détournement is the flexible language of anti-ideology. It appears in communication that knows it cannot claim to embody any definitive certainty. It is language that cannot and need not be confirmed by any previous or supracritical reference. On the contrary, its own internal coherence and practical effectiveness are what validate the previous kernels of truth it has brought back into play. Détournement has grounded its cause on nothing but its own truth as present critique.
