"That was just the sales pitch, to ease public protest over the relinquishment of cultural treasures. All we were really promised was reciprocity in the chain. I'm sure those other things will eventually come to pass, but not necessarily as a direct result. No. Our governments were indulging in the time-honored practice of giving the people a simple, palatable explanation of a complex thing."

"I can see that," he said, and he stretched and yawned. "In. fact, I prefer your interpretation over the official one."

I lit another cigarette.

"Thanks," I said. "I feel obligated to point out, though, that I have always been a sucker for ideas I find aesthetically pleasing. The cosmic sweep of the thing-an interstellar kula chain-affirming the differences and at the same time emphasizing the similarities of all the intelligent races in the galaxy-tying them together, building common traditions ... The notion strikes me as kind of fine."

"Obviously," he said, gesturing then toward the higher stages of the cathedral. "Tell me, are you going to climb the rest of the way up tonight?"

"Probably, in a little while. Did you want to go now?"

"No, no. I was just curious. You generally go all the way to the top, don't you?"

"Yes. Don't you?"

"Not always. In fact, I've recently been keeping more to the middle heights. The reason I asked, though, is that I have a question, seeing that you are in a philosophical mood."

"It's catching."

"All right. Then tell me what it feels like when you reach the top."

"An elation, I guess. A sense of accomplishment, sort of."

"Up here the view is less obstructed. You can see farther, take in more of the features of the landscape. Is that it, I wonder? A better perspective?"

"Part of it, maybe. But there is always one other thing I feel when I reach the top: I always want to go just a little bit higher, and I always feel that I almost can, that I am just about to."
