Schopenhauer on Race

The philosopher Arthur Schopenhauer was one of the earliest proponents of a theory presenting a hierarchical racial model of history, attributing civilisational primacy to the "white races" who gained their sensitivity and intelligence by refinement in the rigorous north.

The highest civilisation and culture, apart from the ancient Indians and Egyptians, are found exclusively among the white races; and even with many dark peoples, the ruling caste or race is fairer in colour than the rest and has, therefore, evidently immigrated, for example, the Brahmins, the Incas, and the rulers of the South Sea Islands. All this is because necessity is the mother of invention because those tribes that emigrated early to the north and there gradually became white, had to develop all their intellectual powers and invent and perfect all the arts in their struggle with need, want and misery, which in their many forms were brought about by the climate. This they had to do in order to make up for the parsimony of nature and out of it all came their high civilisation. 

[Arthur Schopenhauer, Parerga and Paralipomena, Volume II, Section 92]

Despite this, he was adamantly against differing treatment of races, was fervently anti-slavery, and supported the abolitionist movement in the United States. He describes the treatment of "[our] innocent black brothers whom force and injustice have delivered into [the slave-master's] devilish clutches" as "belonging to the blackest pages of mankind's criminal record". [Ibis. "On Ethics," Sec. 5]
