Original spelling and grammar are generally retained, with a few exceptions noted below. Footnotes were renumbered 1–60, changed to endnotes, and moved to the ends of the appropriate essays. Original printed page numbers look like this: {35}.
Page [84]. Table I, originally printed on an unnumbered page between pages 84 and 85, has been moved to page 85, and recast as a nested list so as to function well in ebook format. In particular, large curly brackets “{” intended to combine information on more than one line have been eliminated. Table II, printed between pages 88 and 89 has been treated similarly, and moved to page [88]. Table III, printed between pages 92 and 93 has been moved to page [92] and treated similarly.
Pages [125]–130. In the comparison of Comte’s and Spencer’s propositions, the paragraphs are rewrapped to fit the chosen column widths. Any line-for-line correspondence between paragraphs in the first and second columns that might conceivably have been suggested by the original printed book is thereby negated. The original arrangement of the paragraphs is retained. The table of paragraphs on pp. [131]–132 was treated in the same way. On page [126], the phrase “est essentiellement différent même radicalement opposé”, clearly missing something in the original printed book, was changed to “est essentiellement différent et même radicalement opposé”.
Page [192]. The large white spaces in the clause “Space is either or is ;” are retained from the printed book.
