For the State, only submitting these poor children to the ideology of the work, it would be possible ' ' regener-las' '. From this moment, the poor child if became an object, a place where the power would have to be installed. For this reason, two to know different, however, complementary, had started to inside act and to dispute space of this place: knowing policeman and judiciary knowing. In this direction, the hypothesis of this work is of that the Brazilian State, of liberal character in the delimited period, identified the poor child through the figure of the minor, as that one that needed ' ' interveno' ' of the State to form its citizenship. This child was son of parents ' ' degenerados' ' e, so that he was ' ' salva' ' , preventing itself that she became plus a policy problem, agricultural agents of the State, entrepreneurs and producers had joined efforts to move away it from the conviviality ' ' nefasto' ' of the family, including it in a mission ' ' regeneradora' '. In the first chapter, as theoretical basement, the theories on being able will be analyzed/to know through the vision of Michel Foucault, on the affirmation of the knowledge as ' ' verdade' ' , the disciplinarizao and the relation between being able of the State and knowing of the doctor.
