Material Logic Instructional Videos (DVDs), 2nd Edition


What are the ten ways something can be said to “be”? What are the five ways something can be said of something else? What are the four questions you must answer in order to truly know  something? Ancient and medieval thinkers, from Aristotle to St. Thomas Aquinas, knew the answers to these questions because they had a set of clearly defined and articulated rules for  thinking. These rules, which make up a sort of lost wisdom of the ancients, are now available to modern students in an easy-to-use and accessible format in Memoria Press’ Material Logic program.
