Transcriber's Notes
The following changes have been made to the text as printed:
1. Footnotes have been placed immediately below the paragraph within which they occur, and marked numerically.
2. A period has been removed following the subheading [Gnosticism] (Page 14), for consistency with other subheadings.
3. strenously (Page 51) has been corrected to [strenuously].
4. The missing word I has been inserted in the passage [the next world belongs to him towards whom I have brought it] (Page 78).
5. The name printed as Fitz Gerald (Page 97) has been rendered as [FitzGerald] (the usual form for this writer).
6. A single close-quote mark has been inserted after [vouchsafed to him] (Page 127).
7. karāmat (Page 129) has been changed to [karāmāt].
8. The line beginning [Then he quotes] (Page 160) has had its indentation reduced, as it is part of the main text and not (as printed) part of the preceding quotation.
