Editing How to Read a Book (section)

===Part 1: The Dimensions of Reading===
Here, Adler sets forth his method for reading a non-fiction book in order to gain understanding. He claims that three distinct approaches, or readings, must all be made in order to get the most possible out of a book, but that performing these three levels of readings does not necessarily mean reading the book three times, as the experienced reader will be able to do all three in the course of reading the book just once. Adler names the readings "structural", "interpretative", and "critical", in that order.

''Structural stage'': The first stage of analytical reading is concerned with understanding the structure and purpose of the book. It begins with determining the basic topic and type of the book being read, so as to better anticipate the contents and comprehend the book from the very beginning. Adler says that the reader must distinguish between practical and theoretical books, as well as determining the field of study that the book addresses. Further, Adler says that the reader must note any divisions in the book, and that these are not restricted to the divisions laid out in the table of contents. Lastly, the reader must find out what problems the author is trying to solve.

''Interpretive stage'': The second stage of analytical reading involves constructing the author's arguments. This first requires the reader to note and understand any special phrases and terms that the author uses. Once that is done, Adler says that the reader should find and work to understand each proposition that the author advances, as well as the author's support for those propositions.

''Critical stage'': In the third stage of analytical reading, Adler directs the reader to critique the book. He asserts that upon understanding the author's propositions and arguments, the reader has been elevated to the author's level of understanding and is now able (and obligated) to judge the book's merit and accuracy. Adler advocates judging books based on the soundness of their arguments. Adler says that one may not [[intellectual honesty|disagree]] with an argument unless one can find fault in its reasoning, facts, or premises, though one is free to dislike it in any case.
