Hermans gives us an elaborate and very thorough overview of the ideas of these ‘social Darwinists’, who succeeded in misapproprating the theory of evolution for their personal political interests…. [His] most readable study offers a fascinating sampling of these thinkers and men of action from the late nineteenth century, all under the spell of expected downfall.

The dissertation of Mr Hermans is a brave crusade against the pulverized idea of social Darwinism that arose in the course of time.
