Teach your students to focus on the 'what' and 'content' of reasoning with this challenging curriculum. Focusing on the content of reasoning (material logic) rather than the structure of arguments (formal logic), this workbook provides a lesson and accompanying exercises for 16 weeks' worth of lessons. Includes discussion of the traditional 10 categories; 5 predicables; 4 causes; five elements of classification, plus case study analysis of essays by Thomas Aquinas, Hilaire Belloc, and Francis Bacon. Learn the ten ways something can exist, five ways you can say something about something else, and the four questions you must answer to know what something is! One semester or one-year course. 224 pages, softcover.
