Discipline may be identified neither with an institution nor with an apparatus; it is a type of power, a modality for its exercise, comprising a whole set of instruments, techniques, procedures, levels of application, targets; it is a 'physics' or 'anatomy' of power, a technology.

Being established in my life, buttressed by my thinking nature, fastened down in this transcendental field which was opened for me by my first perception, and in which all absence is merely the obverse of a presence, all silence a modality of the being of sound, I enjoy a sort of ubiquity and theoretical eternity, I feel destined to move in a flow of endless life, neither the beginning nor the end of which I can experience in thought, since it is my living self who think of them, and since thus my life always precedes and survives itself.
