Il me semble que la tache politique actuelle dans une société comme la notre c’est de critiquer le jeu des institutions apparemment les plus neutres … - Michel Foucault

There are moments in life where the question of knowing whether one might think otherwise than one thinks and perceive otherwise than one sees is indispensable if one is to continue to observe or reflect... What is philosophy today... if it does not consist in, instead of legitimizing what we already know, undertaking to know how and how far it might be possible to think otherwise?... The ‘essay’ —which must be understood as a transforming test of oneself in the play of truth and not as a simplifying appropriation of someone else for the purpose of communication—is the living body of philosophy, if, at least, philosophy is today still what it was once, that is to say, an askesis, an exercise of the self, in thought.

Vol I: La volonté de savoir

The different pieces of evidence did not constitute so many neutral elements, until such time as they could be gathered together into a single body of evidence that would bring the final certainty of guilt. Each piece of evidence aroused a particular degree of abomination. Guilt did not begin when all the evidence was gathered together; piece by piece, it was constituted by each of the elements that made it possible to recognize a guilty person. Thus a semi-proof did not leave the suspect innocent until such time as it was completed; it made him semi-guilty; slight evidence of a serious crime marked someone as slightly criminal. In short, penal demonstration did not obey a dualistic system: true or false; but a principle of continuous gradation; a degree reached in the demonstration already formed a degree of guilt and consequently involved a degree of punishment.
