Once you have learned how to progress through the steps of understanding (grammar), evaluating (logic), and expressing an opinion (rhetoric), then turn to the reading lists in Part II. These lists are organized by subject; if you read the books in order, limiting yourself to one field of inquiry (fiction, autobiography, history) at a time, you will find that your earlier reading will set a framework for the books that come later, while your later reading will reinforce and clarify what has come before.
