“I saw a stop sign, and it occurred to me that just as no one expects a stop sign to stop a car, I shouldn’t expect words to substitute for experience. That’s not their job, although words certainly can be misused in that way. The job of words is to direct us toward experience, to round out experience, to facilitate experience, and to give us ways to share at least pale shadows of that experience with those we love. And the job of words is to help us learn to be — and act — human.”
