We may be sure that the characteristic blindness of the twentieth century–the blindness about which posterity will ask, “But how could they have thought that?”–lies where we have never suspected it, and concerns something about which there is untroubled agreement between Hitler and President Roosevelt or between Mr. H. G. Wells and Karl Barth. None of us can fully escape this blindness, but we shall certainly increase it, and weaken our guard against it, if we read only modern books.
C. S. Lewis
A few blindspots come to mind where Hitler and Roosevelt probably would have agreed:
1. Practice is more important than theory.
2. The new is better than the old.
3. Science has the answers for contemporary man.
Can you improve the list?
