„We use the unrevised edition because we believe the revised edition (the revisions were done by Carnegie’s relatives after his death) forcefully makes the language of the book gender neutral and politically correct and takes away from the originality of the work. They even went so far ahead as to make quotes from other people gender neutral and politically correct. Most of the revised editions available today do not include Parts 5 and 6. Even the included parts see many paragraphs and examples omitted. In many places, characters in examples who were male have been edited to be female. It appears that Carnegie’s relatives decided to heavily excise content and highhandedly edit the work to match their own sensibilities and what appears to the webmasters as a feminist agenda. The unrevised edition as on this website is complete without exclusions and edits. We believe this text written by Dale Carnegie himself while he was alive without the alterations made by his relatives after his death is more readable, complete, and enjoyable.“

Thanks for sharing, I had no idea. Looks like I'll have to go look for the original for a reread.
