Erdvig has written much that I'd like to have written about what I've learned in the almost 20 years since I wrote the Visual Valet. He addresses the important issue of how to develop our own worldview and that of our students. I found it much easier to change the philosophy of my students—how they view the world when they are thinking about it, rather than their worldview—how they view the world when they are not thinking about it. Roger Erdvig has a more complicated definition of worldview but still concludes that our worldview is shaped by our experience rather than instruction which shapes our philosophy. The Biblical worldview is what God has revealed about how He views His world, but our personal worldview may be quite different. Learning new knowledge about how God's word and God's world relate changes philosophy but unless we focus on the total environment of a student their "autopilot" won't be transformed even if they have all the "right answers."
