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

Enne Koops in Historisch Tijdschrift Groniek, Groningen University, 2004

It was a motley collection, these social Darwinists, and Mr Hermans has enough on his plate to find the common denominator. The risk appears of a portrait gallery of eminent Victorians, however ably painted; therefore the author at regular intervals takes up stock to determine what can really be called social Darwinistic. (…) Mr Hermans makes us notice a number of important personalities, with their theories, who for a long time have been in everyone’s black book.
