In the words of social Darwinists, radical representatives of nineteenth-century «scientific racism», several of the «races» present in each nation-state mobile phone number list could be obstacles to its full development. For this reason, for them, European countries had to preserve the purity of the white or Caucasian "race" by avoiding its miscegenation with other supposed races seen as inferior. They claimed that the mixture involved dangerously "dissolving" the racial unity that, according to them, characterized European countries. It was for this reason that the polite mobile phone number list ical currents that defended these positions tended to exalt the idea of a "pure race" as the biological and cultural essence of modern nation-states.
Furthermore, social Darwinism considered that it was necessary to preserve the genetic heritage of each "race" and take care of it from mixing with mobile phone number list others,8. For this reason, he maintained that the worst enemy of the national "races" was miscegenation; that mixing between "races" would produce poor offspring and lead to the general decline of the nation.
But what about nation-states where two or more mobile phone number list "races" coexisted? Joseph Arthur de Gobineau, a noted social Darwinist and French ambassador to Brazil between 1869 and 1870, was scandalized by the "interracial crossings" that he observed there9. For him, the fact that Brazil was or was not capable of "achieving a place alongside the luminous civilizations of the northern hemisphere (...) ultimately depended on the incorporation or elimination (...) of those [mestizo] elements"10.
