“You used to walk across town in the pouring rain to use our encyclopedias. We're pretty confident that we can get your kid to click and drag." I think it was the kid's walk in the rain that constituted the real education, at least of the senses and the imagination., Perhaps the child with the CD-ROM encyclopedia will stray from the task at hand, but wandering in a book or a computer takes place within more constricted and less sensual parameters. It's the unpredictable incidents between official events that add up to a life, the incalculable that gives it value. Both rural and urban walking have for two centuries been prime ways of exploring the unpredictable and the incalculable, but they are now under assault on many fronts.”
