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.

Mr Hermans not only demonstrates that utilitarianism is much more interesting and wide ranging than is commonly assumed, he also shows that it is not justified to criticise Mill for being an ‘unsystematic’ thinker. (…) The Mill that Mr Hermans presents in his erudite and excellently written book made great demands on himself, such as ordinary mortals could never satisfy; however, he also was a very prolific and stimulating philosopher, who but little resembled the wooden Victorian schoolmaster looking down on us in photographs and paintings.
