Conspiracy theory and revisionist history.It is a matter of some regret to me that I have been so far unable to continue the series of studies on the French Revolution of which The Chevalier de Boufflers and The French Revolution, a Study in Democracy formed the first two volumes. But the state of the world at the end of the Great War seemed to demand an enquiry into the present phase of the revolutionary movement, hence my attempt to follow its course up to modern times in World Revolution. And now before returning to that first cataclysm I have felt impelled to devote one more book to the Revolution as a whole by going this time further back into the past and attempting to trace its origins from the first century of the Christian era. For it is only by taking a general survey of the movement that it is possible to understand the causes of any particular phase of its existence.
