by Peter Kreeft
This is a great resource for logic teachers and for those who are tasked with developing an overall humanities curriculum ordered toward helping young people to discern and defend the truth rather than training them in cleverness or cynical criticism. In fact, this book is a direct response to the trend in the last half-century that reduces logic to manipulating symbols and evaluating the coherence of closed systems. As such, it is particularly relevant for a Catholic classical curriculum.
Kreeft’s concern is much broader than formal logic; it ranges from Grammar to Logic and on to Rhetoric. I would not recommend this for use as a textbook, though there are select sections from which a teacher might develop lessons and exercises. The book is by no means a quick or easy read and it is probably not one that most will want to read front to back. I would recommend reading the introduction and then skipping around to those topics of most immediate interest.
A Concise Introduction to Logic
by Patrick J. Hurley
This is a good text for teaching formal logic. It is widely used in colleges but is accessible to high school students and its chapters are broken down into short sections that are conducive to presenting in a single lesson. Each section has an ample set of exercises at the end for students to practice. Recent editions are expensive, prohibitively so for high school students, especially since most Catholic schools won’t want to use the full text (I only use chapters 1, 6 and 7) but there are plenty of used, older editions available on-line that are affordable and not out of date.
