In this series, where the resolution to doubt occurred as an event, and the resolution to be wary of the senses as another, and where the decision to act as though one were sleeping will take place, there is a moment where madness is indeed envisaged, but as an eventuality that one cannot assume, and to which one cannot grant access to the game of qualifying transformations (precisely because it would be disqualifying); this moment is by that very action a certain manner of qualifying the meditating subject as being unable to be mad a manner therefore of transforming him by exclusion, by the exclusion of any possibility of madness.
