About those "assured results"

I find that students are bored by textbooks that offer the “assured” results of the collective guild—indeed, not just bored but frequently misled as the “assured” results are neither uncontested nor incapable of additional nuance. I find that students, and all other readers for that matter, learn most deeply and eagerly when they are compelled to wrestle with arguments involving new ideas. In short, my hope is that all readers, whether novice or expert, will find that this book has something to offer.—Matthew W. Bates, Salvation by Allegiance Alone, 7
