Discipline is a mechanism of power which regulates the behaviour of individuals in the social body. This is done by regulating the organisation of space (architecture etc.), of time (timetables) and people’s activity and behaviour (drills, posture, movement). It is enforced with the aid of complex systems of surveillance. Foucault emphasizes that power is not discipline, rather discipline is simply one way in which power can be exercised. He also uses the term ‘disciplinary society’, discussing its history and the origins and disciplinary institutions such as prisons, hospitals, asylums, schools and army barracks. Foucault also specifies that when he speaks of a ‘disciplinary society’ he does not mean a ‘disciplined society’.
