From the interview with Joshua Lutz at The Photobook Club:
[JL]: My favorite component of the book as a medium is how one reads it in such a way that confirms something that they may believe to be true and how a belief system is reinforced by something in the book itself. Basically, If you have a small hint of something that you think is true and apply it to the book that very thing becomes the glasses for which you read the entire book. A younger version of myself fought this as much as I could to make sure people were seeing exactly what I was. Letting go of this is a little scary but ultimately has ended up being really quite spacious.
