The Inequality of Human Races is a seminal work by Arthur de Gobineau that explores the concept of racial hierarchy and its implications for civilization and society. In this book, Gobineau argues that human races are inherently unequal in their intellectual and moral capacities, positing that these differences are significant in determining the fate of civilizations.Gobineau categorizes humanity into three primary races: the white (Aryan), the yellow (Asian), and the black (African), asserting that the white race is superior in terms of cultural achievements and intellectual development. He links the decline of civilizations to the mixing of races, which he claims dilutes the qualities of the superior race. His views reflect the prevailing ethnocentric attitudes of the 19th century and have since been discredited as pseudoscientific.
