In the final pages of Chapter V of Afro-Brazilian Religions Roger Bastide sees, at a given moment in the socio-religious evolution of Brazil, a process of social disorganization which in its extent affects not only blacks but also poor white nationals and stranded immigrants.* As generator of a “ social marginalization,” this process could only be the passage through “a moment of transition” characterized by “the exaggerated speed of change in the country.” According to Bastide, an “organic period” follows: with the “proletarization of the blacks, the assimilation of the immigrants, the general rise in the standard of living of the masses, other phenomena of cultural and social reintegration will appear.” On the religious level the “spiritism of umbanda“ is the expression of this new phase.
