Dianetics belongs to a category of books that will be instantly familiar to anyone who's done time reading the slush pile of unsolicited manuscripts for a book publisher. This kind of book is typically an explanation of life, the universe and everything written by a choleric gentleman (often a retired military officer) who has holed up in a converted basement or former kid's bedroom to hammer out his ideas about how the world works—ideas that have for too long been disregarded by the incompetents and assholes around him. (If you are not familiar with this sort of book, know that you have the slush pile readers of America to thank for that.)
