There is a certain age at which a child looks at you in all earnestness and delivers a long, pleased speech in all the true inflections of spoken English, but with not one recognizable syllable. There is no way you can tell the child that if language had been a melody, he had mastered it and done well, but that since it was in fact a sense, he had botched it utterly.
Don't get me wrong: I love nuclear energy! It's just that I prefer fusion to fission. And it just so happens that there's an enormous fusion reactor safely banked a few million miles from us. It delivers more than we could ever use in just about 8 minutes. And it's wireless!
It’s a secondhand world we’re born into. What is novel to us is only so because we’re newborn, and what we cannot see, that has come before- what our parents have seen and been and done- are the hand-me-downs we begin to wear as swaddling clothes, even as we ourselves are naked. The flaw runs through us, implicating us in its imperfection even as it separates us, delivers us onto opposite sides of a chasm. It is both terribly beautiful and terribly sad, but it is, finally, the fault in the universe that gives birth to us all.
