Beyonce and Jay-Z's baby has a name that puzzles the world. Some don't really give a hoot about the A-list couple's choice for a name, but for those who are still thinking about it, here's a hint at what might be Bey's inspiration for baby Blue Ivy Carter.

Beyonce recently posted a passage from the book on her new Tumblr, saying "The world is blue at its edges and in its depths. This blue is the light that got lost".

The passage is the opening to the second chapter of "A Field Guide to Getting Lost" - "The Blue of Distance" by Rebecca Solnit. And if Beyonce read past that opening passage, she must have understood the depth behind the chapter's name. The passage goes on to say:

For many years, I have been moved by the blue at the far edge of what can be seen seen, that color of horizons, of remote mountain ranges, of anything far away. The color of that distance is the color of emotion, the color of solitude and desire, the color of there seen from here, the color of where you are not. And the color of where you can never go. For the blue is not in the place those miles away at the horizon, but in the atmospheric distance between you and the mountains...Blue is the color of longing for the distances you never arrive in, for the blue world.

Solnit looks into the "blue of distance" without wanting the distance to go away. And if Beyonce and Jay-Z got their inspiration from this beautiful meaning, then we have to give them some credit. The name is deep.
