One of the main mechanisms for access to higher education demanded by Afro-Brazilians are affirmative action policies in the form of social and ethnic-racial quotas. This means understanding the subjects of these policies, discussing and characterising the relationships and intersections that are established between the categories of higher education, race/ethnicity and social class and the possible relationship of autonomy that one of these categories may establish in relation to the other. From a theoretical-methodological point of view, this exercise makes it possible to update and consolidate the analyses of the relationships, conditioning and shifts established between the categories already mentioned, when applied to these policies, as well as to perceive and characterise them as ethnically/racially compensatory or not. It is in the sphere of this admittedly polyphonic and burning issue, which has been mobilising the academic community and wider society even before it was implemented in our country, that this study by Marluce de Souza Oliveira Lima is inserted and presented to us here in the form of a book which, due to its importance and contributions, is strongly recommended reading.
