The author of the most detailed report[648] is one François Charles de Berckheim, special commissioner of police at Mayence towards the end of the Empire, who as a Freemason is naturally not disposed to prejudice against secret societies. In October 1810 he writes, however, that his attention has been drawn to the Illuminati by a pamphlet which has just fallen into his hands, namely the _Essai sur la Secte des Illuminés_, which, like many contemporaries, he attributes originally to Mirabeau. He then goes on to ask whether the sect still exists, and if so whether it is indeed "an association of frightful scoundrels who aim, as Mirabeau assures us, at the overthrow of all law and all morality, at replacing virtue by crime in every act of human life." Further, he asks whether both sects of _Illuminés_ have now combined in one and what are their present projects. Conversations with other Freemasons further increase Berckheim's anxiety on the subject; one of the best informed observes to him: "I know a great deal, enough at any rate to be convinced that the _Illuminés_ have vowed the overthrow of monarchic governments and of all authority on the same basis." Berckheim thereupon sets out to make enquiries, with the result that he is able to state that the _Illuminés_ have initiates all over Europe, that they have spared no efforts to introduce their principles into the lodges, and "to spread a doctrine subversive of all settled government ... under the pretext of the regeneration of social morality and the amelioration of the lot and condition of men by means of laws founded on principles and sentiments unknown hitherto and contained only in the heads of the leaders." "Illuminism," he declares, "is becoming a great and formidable power, and I fear, in my conscience, that kings and peoples will have much to suffer from it unless foresight and prudence break its frightful mechanism [_ses affreux restorts_]." Two years later, on January 16, 1813, Berckheim writes again to the Minister of Police: Monseigneur, they write to me from Heidelberg ... that a great number of initiates into the mysteries of Illuminism are to be found there. These gentlemen wear as a sign of recognition a gold ring on the third finger of the left hand; on the back of this ring there is a little rose, in the middle of this rose is an almost imperceptible dint; by pressing this with the point of a pin one touches a spring, by this means the two gold circles are detached. On the inside of the first of these circles is the device: "Be German as you ought to be"; on the inside of the second of these circles are engraved the words "Pro Patria." Subversive as the ideas of the Illuminati might be, they were therefore not subversive of German patriotism. We shall find this apparent paradox running all through the Illuminist movement to the present day.
