The art of poisoning was therefore known to the Rosicrucians, and, although there is no reason to suppose it was ever practised by the heads of the Fraternity, it is possible that the inspirers of the poisoners may have been perverted Rosicrucians, that is to say, students of those portions of the Cabala relating to magic both of the necromantic and venefic varieties, who turned the scientific knowledge which the Fraternity of the Rosy Cross used for healing to a precisely opposite and deadly purpose. This would explain the fact that contemporaries like the author of the _Examination of the Unknown and Novel Cabala of the Brethren of the Rose-Cross_ should identify these brethren with the magicians and believe them to be guilty of practices deriving from the same source as Rosicrucian knowledge--the Cabala of the Jews. Their modern admirers would, of course, declare that they were the poles asunder, the difference being between white and black magic. Huysmans, however, scoffs at this distinction and says the use of the term "white magic" was a ruse of the Rose-Croix. But of the real doctrines of the Rosicrucians no one can speak with certainty. The whole story of the Fraternity is wrapped in mystery. Mystery was avowedly the essence of their system; their identity, their aims, their doctrines, are said to have been kept a profound secret from the world. Indeed it is said that no real Rosicrucian ever allowed himself to be known as such. As a result of this systematic method of concealment, sceptics on the one hand have declared the Rosicrucians to have been charlatans and impostors or have denied their very existence, whilst on the other hand romancers have exalted them as depositaries of supernatural wisdom. The question is further obscured by the fact that most accounts of the Fraternity--as, for example, those of Eliphas Lévi, Hargrave Jennings, Kenneth Mackenzie, Mr. A.E. Waite, Dr. Wynn Westcott, and Mr. Cadbury Jones--are the work of men claiming or believing themselves to be initiated into Rosicrucianism or other occult systems of a kindred nature and as such in possession of peculiar and exclusive knowledge. This pretension may at once be dismissed as an absurdity; nothing is easier than for anyone to make a compound out of Jewish Cabalism and Eastern theosophy and to label it Rosicrucianism, but no proof whatever exists of any affiliation between the self-styled Rosicrucians of to-day and the seventeenth-century "Brothers of the Rosy Cross."[263]
