Abstract: A device for assisting thought processes in decision making. The device is a book having a front cover bearing a title in characters and a rear cover bearing the title but wherein the characters comprising the title are inverted with respect to the front cover. Thus, the book may be opened sensibly from either the front or the back. A plurality of pages, each page bearing self-contained text, are disposed between the front and rear covers with the text inverted on alternate pages. A person contemplates a problem then opens the book either from the front or the rear to reveal a random page. The text that appears in non-inverted characters on the exposed page is read to provide guidance in solving the problem.
