[Theoretical reflections regarding subjects of praxis and subjects of antithesis in Brazilian health reform].

The Brazilian Health Reform has been recognized as a project that transcends the sectoral dimension in that it considers an expanded concept of health and social determination, which distinguishes it from other health system reforms of the twentieth century. This article aims to contribute to the construction of the concepts subjects of praxis and subjects of antithesis by discussing certain challenges of praxis in the Brazilian Health Reform, the constitution of social subjects and the emergence of subjects of antithesis. The article argues that theoretical reflection can contribute to political analysis in health and discern the power of a praxis that destabilizes the conservative character of the passive revolution.
