The name of Illuminee which this Sect (the most disastrous in its principles, the most extensive in its views, the most atrociously cunning in its means) has chosen, is of ancient standing in the annals of disorganizing Sophistry. It was the name which Manes and his disciples first affected, gloriantur Manichæi se de cælo illuminatos. The first Rosicrucians also, who appeared in Germany, called themselves Illuminees. And later, in our time, the Martinists (with many other sects) have pretended to Illuminism. As an outline for history I distinguish them by their plots and tenets, and will reduce them into two classes, the Atheistical and the Theosophical Illuminees. These latter more particularly comprehend the Martinists, whom I have already mentioned in my second volume, and the Swedenbourgians, whom I shall mention in their proper place, where also I shall give what information I have been able to collect relating to them. The Atheistical Illuminees are the objects of the present volume, and it is their conspiracy that I mean to disclose.
The very numerous letters, books, and manuscripts, which I have received since the publication of my proposals, has rendered it impossible for me to comprise the proposed investigation in one volume. The baleful projects of the Sect and the laws for their execution are so strangely combined, that I thought it necessary to begin by making my reader perfectly acquainted with its code; that is to say, with the regular progression of its degrees, mysteries, and government.
This alone requiring an entire volume, I am reduced to the necessity of giving a fourth, in which I shall develope the history of Illuminism, and make piracy to the French Revolution. I have more particularly applied myself to the investigation of the legislative part of this conspiring Sect, as no work has yet been published in which the whole of their code is to be found. Detached parts only were to be met with scattered throughout the papers which had been seized by the public authority. These I have collected and digested; thus enabling the reader more easily to judge what has been and what must have been the result of such laws. In such an undertaking, I feel myself bound to lay before the public an account of the documents on which I ground my proofs. The following then is a list of the principal works, with a few observations on each, that the reader may form his own judgment as to their authenticity.
