社会進化論
Social Darwinism was predominantly found in laissez-faire societies where the prevailing view was that of an individualist order to society. A different form of social Darwinism was part of the ideological foundations of Nazism and other fascist movements. This form did not envision survival of the fittest within an individualist order of society, but rather advocated a type of racial and national struggle where the state directed human breeding through eugenics. Names such as "Darwinian collectivism" or "Reform Darwinism" have been suggested to describe these views to differentiate them from the individualist type of social Darwinism.
