"It is important to realize, however, that the exaltation of the Indo-Europeans or the Aryans—especially during the nineteenth century, but also later, for example, for the socialist Gordon Childe—was a song of praise for the modern citizen with a scientific outlook, liberal values, and humanistic ideals. In the nineteenth century, the Indo-Europeans were mainly models for a progressive bourgeois ideology, and the attacks on Jewish and Semitic religiosity (which sometimes included Christianity) aimed to form a worldview that fitted modern society and was not necessarily connected to any racial ideology."
