Good work, like good talk or any other form of worthwhile human relationship, depends upon being able to assume an extended shared world.
What makes Berry's observation sharp is his refusal to treat work as mere transaction—he's arguing that craftsmanship itself requires a kind of intimacy, a mutual understanding between maker and audience that extends across time. The "extended shared world" isn't just about shared values; it's about assuming your customer or colleague will still be around tomorrow, that your work matters in a context larger than quarterly profits. When a carpenter builds a staircase to last fifty years instead of five, she's betting on that extended world existing—and in doing so, she creates it. That's why so much contemporary work feels hollow: we've stopped assuming we'll answer for it.
