Razor's Book of It?

Razor's Book of "IT?" contains descriptions of things and challenges the reader to decide what "IT" might be. William wrote the book using vague descriptions with no one thing in mind. Some things may seem obvious, but you must allow your mind to wonder what else "IT" could be. Does "IT" exist or is "IT" something imaginary? The first time you read a writing "IT" maybe one thing, but upon rereading the description, you change your mind and "IT" becomes something else. Can you handle the challenge of deciding what "IT" is?
