David Morrow and Anthony Weston build on Weston's acclaimed A Rulebook for Arguments to offer a complete textbook for a course in critical thinking or informal logic.  The third edition of Workbook contains the entire text of the recent fifth edition of the Rulebook , supplementing this core text with extensive further explanations and exercises. Updated and improved homework exercises ensure that the examples continue to resonate with today's students. Roughly one-third of the exercises have been replaced with updated or improved examples. A new chapter on engaging constructively in public debates -including five new sets of exercises-trains students to engage respectfully and constructively on controversial topics, an increasingly important skill in our hyper-partisan age. Three new critical thinking activities offer further opportunities to practice constructive dialogue.
