All this implies that … the so-called classical liberals, who nowadays call themselves neo-liberals or libertarians, claim Mill’s ideas and contend they follow in his footsteps. The Dutch historian Cor Hermans modifies this image thoroughly in his highly readable book Een Engelsman in Frankrijk …. In it he doesn’t deny that the famous philosopher played an important role in the history of European liberalism, but he demonstrates … that [Mill] was also influenced, and substantially so, by the Romantic Movement, socialism, and positivism.

It’s his merit that he has placed Darwin himself clearly in the foreground as originator of the debate on social evolution in the second half of the nineteenth century. Against this there is the drawback that Mr Hermans has not resisted the temptation to walk every side-road he encountered in his long trail of study. He needs quite a lot of space to both distinguish and connect all the diverse currents. (…) In spite of these critical remarks, in my final verdict appreciation for this clever piece of work of Mr Hermans takes precedence.
