If we admit the possibility that Frederick the Great and the Stricte Observance, working through an inner circle of Freemasons at the Lodge St. Theodore, may have provided the first impetus and that Kölmer initiated Weishaupt into Oriental methods of organization, the source of inspiration from which Weishaupt subsequently drew his anarchic philosophy still remains obscure.

But no documentary evidence has ever been produced in support of these statements. It is therefore necessary to examine them in the light of probability.
Now, as I have already shown, the theosophical ideas of the Cabala play no part in the system of Illuminism; the only trace of Cabalism to be found amongst the papers of the Order is a list of recipes for procuring abortion, for making aphrodisiacs, Aqua Toffana, pestilential vapours, etc., headed "Cabala Major."
