10. O Governo da conduta : o poder médico e a liberdade dos indivíduos na sociedade contemporânea / The Government s conduct : medical power and freedom of individuals in contemporary society
The art of governing our own existence and of others has become an indispensable question for the constitution of the ways of subjectivity at the modernity. Michel Foucault has developed a rich and complex analytical perspective of this theme starting from the studies about the liberal governmentality. At the present time, a series of transformations on the
