Works such as Arthur de Gobineau's An Essay on the Inequality of the Human Races (1853–1855) may be considered one of the first theorizations of this new racism, founded on an essentialist notion of race, which opposed the former racial discourse, of Boulainvilliers for example, which saw in races a fundamentally historical reality, which changed over time. Gobineau, thus, attempted to frame racism within the terms of biological differences among humans, giving it the legitimacy of biology.
