I recently came across an interview with Alvin Plantinga done in 2011. In it he was asked some questions about what brought him back, where he thinks the current state of Calvin College is, and some questions about philosophy. When asked what three books every Calvin alum should read he responded with the following books:
Plato’s Republic. We ought to have more opportunities for people of all ages to engage that text. Another is Jonathan Edwards’ A Treatise Concerning Religious Affections. I didn’t read this volume until I was 50; I should have read it when I was 20. Most people only know Edwards through his fiery sermon “Sinners in the Hands of an Angry God,” because it is often included in anthologies. Every minister in the time of Edwards had to have a “fire and brimstone” sermon in his back pocket. But this sermon is so unlike Edwards and the rest of his work. He was a thoughtful and loving teacher and scholar. The third book would be Augustine’s Confessions.
Plato, Jonathan Edwards, and Augustine. I think that is quite a list. I completely agree with him, those are three books any well educated person should read.
