This article presents some aspects of the notion of ‘panoptism’, starting from the considerations and reflections of the French philosopher Michel Foucault, particularly in the books he published in the period between 1971 and 1976, together with the lectures given at the Collège de France also in those years. Moreover, the discussion will stop at the present moment, showing that panopticism has generated practices of power, rules, uses and habits that are part of our daily life and that deeply interfere in the ways of acting, relating and producing subjectivities and subjections.
