Darwin gave to Malthus views the
scientific validation which allowed to translate them in a social doctrine.
This doctrine is named Social Darwinism, a doctrine which considers wars of
conquest an application, to the human species, of the law of natural selection.
According to Social Darwinism there is a biological reason for disparities:
less-fit individuals and nations must remain relegated to the primitive stage.
This ideology has been at the basis of colonialism, eugenics, fascism, and
savage capitalism.
