Often times the word social construct is thrown around in various theoretical and general works without ever being defined or discussed. However, understanding what is meant by race as a social construct is vital to understanding the capacity race has to intersect and affect other aspects and domains of life and society, as well as how to dismantle it. To begin, a social construct is ontologically subjective, but epistemologically objective. It is ontologically subjective in that the construction and continued existence of social constructs are contingent on social groups and their collective agreement, imposition, and acceptance of such constructions. There is nothing absolute or real about social constructions in the same way as there is something absolute and real about rocks, rivers, mountains, and in general the objects examined by physics. Race, although it does not exist in the world in any ontologically objective way, it still is real in society (as opposed to nature). Race is a social construction that has real consequences and effects. These effects, consequences and the notion that race is ontologically subjective is epistemologically objective. We know that race is something that is real in society, and that it shapes the way we see ourselves and others.
