There are four major theories on what the Intended Purpose is. The first three are unknown. The fourth theory is known, but is wrong.

The fifth theory of the Intended Purpose (the "Fifth Theory") is not yet a theory, it's still more of a conjecture, but it has a lot of things going for it and everyone's really pulling for the Fifth Theory and thinks it's well on its way to theory-hood.

3.2.1 Unsubstantiated a.s.sertion (status: in dispute)

Whatever the Intended Purpose may be, this much is clear: the book is a system, method, and s.p.a.ce for a comprehensive categorization of all objects, categories of objects, categories of categories of objects, etc.

4 What there is not 5 Mode of propagation 5.1 How the book changes hands

On the left-facing inside cover of The Framing Book, we find the word "DEDICATED," and underneath, two lines labeled

"From: _______________________________"

and

"To: __________________________________."

5.2 Each possessor of the book

attempts to impose her numbered ordering of the world by adding categories.

5.3 At some point, whether out of frustration or a sense of completion, or a desire to impose such system on others,

a possessor will pa.s.s the book on to another user, by excising his or her name from the To line, placing the name in the From line, and then writing in the name of the next possessor of the book in the To line. The excision should be performed with the same instrument used to cut new pages.

6 As you may have realized 6.1 What this means is

The Book of Categories contains what is, in essence, its own chain of t.i.tle. It is a system of world ordering that has, encoded into itself, a history of its own revision and is, in that sense, the opposite of a palimpsest. Nothing is ever overwritten in The Book of Categories, only interspersed, interlineated, or, to be more precise, interpaginated.

has possessed the book seventy-three times. No other individual has owned it more than six times.

7 Why 7.1 Why

would someone ever give this book away?

8 A man 8.1 Looking for what was there 8.1.1 Trying to name it 8.1.1.1 Naming being one way

to locate something not quite lost, and not quite found

8.1.1.1.1 A name also seeming

to be a necessary AND sufficient condition to possession of an idea, a name being a kind of idea-cage.

10.1 Little is known about Chang, a general in the Chinese army, except that he is believed to have lost a child, a newborn daughter, in a freak accident while on a brief holiday with his family.

9 Something else you need to realize about the book 9.1 Is that

The sheer number of pages in the book is such that ordinary human fingers cannot turn the pages in a reliably repeatable fashion. Simply breathing in the same room as the book will cause the book's pages to flail about wildly. Even the Brownian motion of particles has been known to move several hundred pages at a time.

9.2 If you ever lose your place in the book

it is unlikely that you will ever be able to return to the same page again in your lifetime.

10.1.1 The incident

Onlookers who witnessed the incident say there were no words in their language to describe what occurred, only that "the water took her" and that although "nothing impossible happened," it was, statistically speaking, a "once-in-a-universe event."
