“We guess,” he said, “that the Message is the instructions for building a machine. Of course, we have no knowledge about how to decode the Message. The evidence is in internal references. I give you an example. Here on page 15441 is a clear reference to an earlier page, 13097, which, by luck, we also have. The later page was received here in New Mexico, the earlier one at our observatory near Tashkent. On page 13097 there is another reference, this to a time when we were not covering all longitudes. There are many cases of this back referencing. In general, and this is the important point, there are complicated instructions on a recent page, but simpler instructions on an earlier page. In one case there are eight citations to earlier material on a single page.”
“That’s not an awfully compelling arguments, guys,” replied Ellie. “Maybe it’s a set of mathematical exercises, the later ones building on the earlier ones. Maybe it’s a long novel–they might have very long lifetimes compared to us–in which events are connected with childhood experiences or whatever they have on Vega when they’re young. Maybe it’s a tightly cross-referenced religious manual.”
“The Ten Billion Commandments.” Der Heer laughed.
“Maybe,” said Lunacharsky, starting through a cloud of cigarette smoke out the window at the telescopes. They seemed to be staring longingly at the sky. “But when you look at the patterns of cross- references, I think you’ll agree it looks more like the instruction manual for building a machine. God knows what the machine is supposed to do.”

Ideas and Opinions (1954)
She could recall the exact moment when, on one of many trips to Washington, she discovered that she was falling in love with Ken der Heer.
Arrangements for the meeting with Palmer Joss seemed to be taking forever. Apparently Joss was reluctant to visit the Argus facility; it was the impiety of the scientists, not their interpretation of the Message, he now said, that interested him. And to probe their character, some more neutral ground was needed. Ellie was willing to go anywhere, and a special assistant to the President was negotiating. Other radio astronomers were not to go; the President wanted it to be Ellie alone.
Ellie was also waiting for the day, still some weeks off, when she would fly to Paris for the first full meeting of the World Message Consortium. She and Vaygay were coordination the global data-collection program. The signal acquisition was now fairly routine, and in recent months there had been not one gap in the coverage. So she found to her surprise that she had a little time on her hands. She vowed to have a long talk with her mother, and to remain civil and friendly no matter what provocation was offered. There was an absurd amount of backed-up paper and electronic mail to go through, not just congratulations and criticisms from colleagues, but religious admonitions, pseudoscientific speculations proposed with great confidence, and fan mail from all over the world. She had not read The Astrophysical Journal in months, although she was the first author of a very recent paper that was surely the most extraordinary article that had ever appeared in the august publication. The signal from Vega was so strong that many amateurs–tired of “ham” radio–had begun constructing their own small radio telescopes and signal analyzers. In the early stages of Message acquisition, they had turned up some useful data, and Ellie was still besieged by amateurs who thought they had acquired something unknown to the SETI professionals. She felt an obligation to write encouraging letters. There were other meritorious radio astronomy programs at the facility–the quasar survey, for example–that needed attending to. But instead of doing all these things, she found herself spending almost all her time with Ken.
Of course, it was her duty to involve the President’s Science Adviser in Project Argus as deeply as he wished. It was important that the President be fully and competently informed. She hoped the leaders of other nations would be as thoroughly briefed on the findings from Vega as was the President of the United States. This President, while untrained in science, genuinely liked the subject and was willing to support science not only for its practical benefits but, at least a little, for the joy of knowing. This had been true of few previous American leaders since James Madison and John Quincy Adams.
Still, it was remarkable how much time der Heer was able to spend at Argus. He did devote an hour or more each day in high-bandpass scrambled communications with his Office of Science and Technology Policy in the Old Executive Office Building in Washington. But the rest of the time, as far as she could see, he was simply… around. He would poke into the innards of the computer system, or visit individual radio telescopes. Sometimes an assistant from Washington would be with him; more often he would be alone. She would see him through the open door of the spare office they had assigned him, his feet propped up on the desk, reading some report or talking on the phone. He would offer her a cheery wave and return to his work. She would find him talking casually with Drumlin or Valerian; but equally so with junior technicians and with the secretarial staff, who had on more than one occasion pronounced him, within Ellie’s hearing, “charming.”
Der Heer had many questions for her as well. At first they were purely technical and programmatic, but soon they extended to plans for a wide variety of conceivable future events, and then to untrammeled speculation. These days it almost seemed that discussion of the project was only a pretext to spend a little time together.
One fine autumn afternoon in Washington, the President was obliged to delay a meeting of the Special Contingency Task Group because of the Tyrone Free crisis. After an overnight flight from New Mexico, Ellie and der Heer found themselves with an unscheduled few hours, and decided to visit the Vietnam Memorial, designed by Maya Ying Lin when she was still an undergraduate architectural student at Yale. Amidst the somber and doleful reminders of a foolish war, der Heer seemed inappropriately cheerful, and Ellie began again to speculate about flaws in his character. A pair of General Service administration plainclothes security people, their custom-molded, flesh-colored earpieces in place, followed discreetly.
He had coaxed an exquisite blue caterpillar to climb aboard a twig. It briskly padded along, its iridescent body rippling with the motion of fourteen pairs of feet. At the end of the twig, it held on with its last five segments and failed the air in a plucky attempt to find a new perch. Unsuccessful, it turned itself around smartly and retraced its many steps. Der Heer then changed his clutch on the twig so that when the caterpillar returned to its starting point , there was again nowhere to go. Like some caged mammalian carnivore, it paced back and forth many times, but in the last few passages, it seemed to her, with increasing resignation. She was beginning to feel pity for the poor creature, even if it proved to be, say, the larva responsible for the barley blight.
“What a wonderful program in this little guy’s head!” he exclaimed. “It works every time– optimum escape software. And he knows not to fall off. I mean the twig is effectively suspended in air. The caterpillar never experiences that in nature, because the twig is always connected to something. Ellie, did you ever wonder what the program would feel like if it was in your head? I mean, would it just seem obvious to you what you had to do when you came to the end of a twig? Would you have the impression you were thinking it through? Would you wonder how you knew to shake your front ten feet in the air but hold on tight with the other eighteen?”
She inclined her head slightly and examined him rather than the caterpillar. He seemed to have little difficulty imagining her as an insect. She tried to reply noncommittally, reminding herself that for him this would be a matter of professional interest.
“What’ll you do with it now?”
“I’ll put it back down in the grass, I guess. What else would you do with it?”
“Some people might kill it.”
“It’s hard to kill a creature once it lets you see its consciousness.” He continued to carry both twig and lava.
They walked for a while in silence past almost 55,000 names engraved in reflecting black granite.
“Every government that prepares for war paints its adversaries as monsters,” she said. “They don’t want you thinking of the other side as human. If the enemy can think and feel, you might hesitate to kill them. And killing is very important. Better to see them as monsters.”
