The third lesson I teach is indifference. I teach children not to care too much about anything, even though they want to make it appear that they do. How I do this is very subtle. I do it by demanding that they become totally involved in my lessons, jumping up and down in their seats with anticipation, competing vigorously with each other for my favor. It’s heartwarming when they do that; it impresses everyone, even me. When I’m at my best I plan lessons very carefully in order to produce this show of enthusiasm. But when the bell rings I insist they drop whatever it is we have been doing and proceed quickly to the next work station. They must turn on and off like a light switch. Nothing important is ever finished in my class nor in any class I know of. Students never have a complete experience except on the installment plan.
Indeed, the lesson of bells is that no work is worth finishing, so why care too deeply about anything? Years of bells will condition all but the strongest to a world that can no longer offer important work to do. Bells are the secret logic of school time; their logic is inexorable. Bells destroy the past and future, rendering every interval the same as any other, as the abstraction of a map renders every living mountain and river the same, even though they are not. Bells inoculate each undertaking with indifference.
