Punctuation and spelling were made consistent when a predominant preference was found in this four-volume set; otherwise they were not changed.

Simple typographical errors were corrected. Inconsistent capitalization has not been changed.

Ambiguous hyphens at the ends of lines were retained.

Infrequent spelling of "Plotinus" changed to the predominant "Plotinos."

Several opening or closing parentheses and quotation marks are unmatched; Transcriber has not attempted to determine where they belong.

Page 1030: The opening parenthesis in "(Nor would he be troubled if the members" either has no match or shares one with a subordinate phrase. Such "sharing" occurs elsewhere in this four-volume set.

Page 1059: "(the former for their ferocity," has no matching closing parenthesis.

Page 1188, footnote 268 (originally 71): The opening parenthesis in "(the principal power of the soul," has no match, or shares one with a subordinate phrase.

Page 1218: The opening quotation mark just before 'He who possesses the virtues' has no matching closing quotation mark.

Page 1262: The opening quotation mark just before 'The intelligible is of a nature' has no matching closing quotation mark.

Page 1265: The opening quotation mark just before 'be in relation with a place,' has no matching closing quotation mark.

Page 1265: Heading "B." is printed here in the same size as heading "A." on page 1261. In the source, it was printed in the same size as the smaller headings under "A."

Page 1313: Chapter number is "VII." but there is no earlier "VI."

Page 1318: The opening quotation mark just before 'Being and Essence;' has no matching closing quotation mark.

Page 1327: The first few lines were misprinted, with the sub-heading "IMPORTANCE IN THE PAST." in the middle of the first paragraph and part of a word missing from that paragraph. This eBook attempts to correct that.

Concordance Issues

Entries in the Concordance have not been systematically checked for accuracy; some errors have been corrected, but others probably remain. Detected errors are noted below.

Most "see"-type references to other entries in the Concordance have not been linked because their targets could not be reliably determined.

Page ii: "Alone with the alone... 1-550" corrected to 1-50.

Page vi: "Being and actualization... 30-784" corrected to 39-784.

Page viii: "Castration", second reference, "v. 8.13 (31-573)." does not belong here.

Page xvii: "Effusion", last word "reation" could be "reaction" or "reason".

Footnote Issues

In these notes, "anchor" means the reference to a footnote, and "footnote" means the information to which the anchor refers. Anchors occur within the main text, while footnotes are grouped in sequence at the end of this eBook. The structure of the original book required some exceptions to this, as explained below.

The original text used chapter endnotes. In this eBook, they have been combined into a single, ascending sequence based on the sequence in which the footnotes (not the anchors) occurred in the original book, and placed at the end of the main text, just before the Concordance.

Four kinds of irregularities occurred in the footnotes:

1. Some footnotes are referenced by more than one anchor, so two or more anchors may refer to the same footnote.
2. Some anchors were out of sequence, apparently because they were added afterwards or because they are share a footnote with another anchor. They have been renumbered to match the numbers of the footnotes to which they refer.
3. Some footnotes have no anchors. These are noted below.
4. One footnote was misprinted beyond repair, and the next three footnotes were missing. These are noted below.

Page 1076: Footnote 61 (originally 42) has no anchor; the missing anchor would be in page range 1062–1064.

Page 1121: Footnote 100 (originally 4) has no anchor; the missing anchor would be in page range 1091–1093.

Page 1121: Footnote 103 (originally 7) has no anchor; the missing anchor would be in page range 1094–1097. Anchor 99 (originally 3) on page 1094 could be the missing anchor, as that number also is used on page 1091.

Page 1188: Footnote 210 (originally 13) has no anchor; the missing anchor would be on page 1171 or 1172.

Page 1189: Footnote 226 (originally 29) has no anchor; the missing anchor would be on page 1174 or 1175.

Page 1253: Footnote 329 (originally 9) has no anchor; the missing anchor would be in page range 1219–1226.

Page 1287: Footnote 469 (originally 98) has no anchor; the missing anchor would be on page 1287.

Page 1333: Footnote 758 (originally 21) appears to be misprinted, and the next three footnotes 759–761 (originally 22–24) are missing.
