In brief, over-achieving self-motivated elites create liberal democracy and industrial economies. Liberal democracy and industry lead to the emergence of the “mass man”, self-defined as not of the elite and hostile to existing elite groups and institutions. The mass man, by strength of numbers and through the democratic institutions which enabled his emergence, seizes the levers of power and begins to use the State to gratify his immediate desires. But, unlike the elites who created the State, the mass man does not think or plan in the long term, and is disinclined to make the investments and sacrifices which were required to create the civilisation in the first place, and remain necessary if it is to survive. In this consists the crisis of civilisation, and grasping this single concept explains much of the history of the seven decades which followed the appearance of the book and events today. Suddenly some otherwise puzzling things start to come into focus, such as why it is, in a world enormously more wealthy than that of the nineteenth century, with abundant and well-educated human resources and technological capabilities which dwarf those of that epoch, there seems to be so little ambition to undertake large-scale projects, and why those which are embarked upon are so often bungled.
