The other thought I had is that Bill uses the phrase again, without quotation marks, in the Into Action chapter, on page 81: "Our design for living is not a one-way street."?
So perhaps Bill is quoting himself? Although the phrase with quotation marks comes earlier in the book than the original, so... ? Maybe one section was written before the other, but ended up later being moved?
¡°a design for living¡± is in quotation marks on page 28 of chapter 2 of the big book, I¡¯m wondering why? Is it in reference to another text or quote from the author (Bill W.)??
Looking for facts over opinions, but open to hearing what others have to share.
