'[Eventalization] means making visible a singularity at places where there is a temptation to invoke a historical constant, an immediate anthropological trait or an obviousness that imposes itself uniformly on all. To show that things weren’t ‘necessary as all that’; it wasn’t as a matter of course that mad people came to be regarded as mentally ill; it wasn’t self-evident that the only thing to be done with a criminal was to lock them up; it wasn’t self-evident that the causes of illness were to be sought through individual examination of bodies; and so on. A breach of self-evidence, of those self-evidences on which our knowledges, acquiescences and practices rest: this is the first theoretico-political function of eventalization.'
