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.
9. Index: The character ʿ has been added in the words [Abu ’l-Khayr al-Aqtaʿ], [ʿAlāʾuddīn], [muʿjizat], [Muʿtazilites], and [Rābiʿa].
10. Apparent inconsistencies in whether hyphens occur in the word pairs well known, passed away, and above mentioned are judged to be due to differences in sense, and no amendments have been made.
