Analysing the works of social theorists such as Herbert Spencer, Alfred Russell Wallace, Ernst Haeckel, and Alfred Schäffle, as well as Darwin’s own work, Dr Hermans concludes that, although not a homogeneous ideology, different versions of social Darwinism all centred around the general notion that modern society could not, in the long run, disrupt natural selection without grave consequences.

International Review of Social History, vol. 51, 2006

Mr Hermans sets out … to discover the essence of social Darwinism. This results in an a-historic approach …. [Still] the investigation of Mr Hermans certainly is worth reading. For those who will not worry too much about the formulation of the historical problem to solve, this book offers a fine survey, nicely written, of the many variants of social Darwinism. It’s a valiant undertaking to add a fresh contribution to the so-called ‘Darwin industry’, even venturing to come up with something novel to it.
