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.
