Indeed, with a few exceptions, the sense is clear enough to make the volume agreeable reading even to the uninitiated.... The seventeenth century was an age of plain speaking, and Vaughan, when differing from anyone, sometimes uses terms more forcible than elegant. Mr. Waite supplies some interesting information about the history of occultism in his 'Introductory Lecture on the Esoteric Literature of the Middle Ages, and on the Underlying Principles of Theurgic Art and Practice in Western Christendom.'"
