"That the "problem" of reading was simultaneously caused and invented by schools and their insistence on teaching "classes" and "groups"---and by the resulting quest of teachers to find ways to "teach," i.e., ways to standardize and to measure. That there simply is no way to measure what is crucial about reading a book--namely whether or not the kid liked the book, whether he imagined himself involved in the adventures of Jim Hawkins, whether or not he was changed by it. "This should change your life," says Rilke. Who can measure that? And yet it is all that counts."
