Covering topics in logic too often reserved for a college course, Intermediate Logic simplifies various elements of propositional and symbolic logic, including truth tables and formal proofs of validity. While this textbook/workbook can be used for one year's worth of study, older students may work through Introductory Logic and Intermediate Logic in a school year. Recommended for grades 8 and up. 20 lessons/35 exercises.
My hero, Leonardo of Pisa, was born the same year that the famous tower of his birthplace went up (and though it was upright at the time, it began leaning soon thereafter). We share this odd bit of trivia; I was born in Seattle the same year (same month, actually) that the famous tower of that city (the Space Needle) was erected, in February of 1962 for the World's Fair.
My dad worked for Boeing (like most of his friends), and after graduating with a B.S. in M.E. in 1984 from Washington State University, I followed Dad, working on the 757 in Renton, Washington. While working at Boeing I met my lovely wife Giselle (she was on the AWACS program). We now have four children: Jamie, Josiah, Jacqueline, and Jonathan.
After five years I left engineering forever and moved my family to Moscow, Idaho, where since 1989 I have been teaching at Logos School. Logos is a private Christian school, and the flagship of ACCS. There I teach logic, calculus, physics, and rhetoric. I teach logic to 8th graders from the textbooks written by Doug Wilson and myself. I am grateful to God that so many others have benefited from these books.
I enjoy teaching, reading, acting, and playing games with my friends and family.
