I wonder if it's more of an adaptation or coping mechanism than a foundational principle. I think these people cannot bear to actually digest the cynical view of what they are doing in the world so they grasp for something more esoteric and hold that up as guiding principles.
If they were actually doing something good, they wouldn't have to find a book that explains why what they're doing is good in some indirect way. If you look at Jimmy Wales' guiding philosophy, for example, it is clearly and directly correlated to the work being done at Wikipedia. There's no jumping through hoops, because most people agree that Wikipedia is a good thing.
Any idea what the book was?
