Sachs (2005) states, A Differentail Diagnosis, which identifies the policies and investments that the country needs to achieve the Millennium Development Goals.
Freire (1972) states, it is absolutely essential that the oppressed participate in the revolutionary process with an increasingly critical awareness of their role as Subjects of the transformation.I believe that what Sachs is espousing is a national diagnosis for what "ills" a country. And what Freire is espousing is individual and / or community involvement in the process of finding a remedy for the "ills". Sachs approach is too macro, communities within any given country differ to greatly to have a country level differential diagnosis. A Freirian approach would be a community diagnosis.
