Learning wonders rather than accumulates. Learning wonders about the things we claim to know and about knowing at all. It wonders if knowing is all it is cracked up to be. Learning is subversive. What it asks you to pay in tuition is most of what you had thought was true, and what was necessary, and what was enduringly so. Especially it asks you to fork over most of what you thought you needed. To learn you have to trade in your comfort and your certainty for wonder, and wonder when it is fully employed and in good working order generally won’t let you build a new religion upon it.
