In a revolution, when the ceaseless slow accumulation of centuries bursts into volcanic eruption, the meteoric flares and flights above are a meaningless chaos and lend themselves to infinite caprice and romanticism unless the observer sees them always as projections of the sub-soil from which they came. The writer has sought not only to analyse, but to demonstrate in their movement, the economic forces of the age; their moulding of society and politics, of men in the mass and individual men; the powerful reaction of these on their environment at one of those rare moments when society is at boiling point and therefore fluid.
