"What then is taking place in the world, and why do priests and potentates tremble? What secret power threatens tiaras and crowns? A few bedlam-ires are roaming from land to land, concealing, as they say, the Philosophical Stone under their ragged vesture. They can change earth into gold, and they are without food or lodging! Their brows are encircled by an aureole of glory and by a shadow of ignominy!
What secret do these men bear with them to their tomb? Why are they wondered at without being understood? Why are they condemned unheard? Why are they initiates of those terrific secret sciences of which the Church and society are afraid? Why are they acquainted with things of which others know nothing? Why do they conceal what all men burn to know? Why are they invested with a dread and unknown power? The occult sciences! Magic! These words will reveal all and give food for further thought! De omni re scribili et quibusdum aliis.
But what, as a fact, was this Magic? What was the power of these men who were at once so proud and so persecuted? If they were really strong, why did they not overcome their enemies? But if they were impotent and foolish, why did people honour them by fearing them? Does Magic exist? Is there an occult knowledge which is in truth a power and works wonders comparable to the miracles of authorized religions? To these two palmary questions we make answer by an affirmation and a book. The book shall justify the affirmation, and the affirmation is this: There was and there still is a potent and real Magic; all that is said of it in legend is true after a certain manner, yet--contrary to the common course of popular exaggeration--it falls below the truth. There is indeed a formidable secret, the revelation of which has once already transformed the world, as testified in Egyptian religious tradition ..."
There is one sole, universal and imperishable dogma, strong as supreme reason; simple, like all that is great; intelligible, like all that is universally and absolutely true; and this dogma is the parent of all others. There is also a science which confers on man powers apparently superhuman."
