Cure the symptoms, cure the disease.

But Leavitt wondered about the Scoop organism. Could they cure the disease by treating the blood clotting? Or was the clotting secondary to some more serious, disorder?

There was also another concern, a nagging fear that had bothered him since the earliest planning stages of Wildfire. In those early meetings, Leavitt had argued that the Wildfire team might be committing extraterrestrial murder.

Leavitt had pointed out that all men, no matter how scientifically objective, had several built-in biases when discussing life. One was the assumption that complex life was larger than simple life. It was certainly true on the earth. As organisms became more intelligent, they grew larger, passing from the single-celled stage to multicellular creatures, and then to larger animals with differentiated cells working in groups called organs. On earth, the trend had been toward larger and more complex animals.

But this might not be true elsewhere in the universe. In other places, life might progress in the opposite direction—toward smaller and smaller forms. Just as modern human technology had learned to make things smaller, perhaps highly advanced evolutionary pressures led to smaller life forms. There were distinct advantages to smaller forms: less consumption of raw materials, cheaper spaceflight, fewer feeding problems . . .

Perhaps the most intelligent life form on a distant planet was no larger than a flea. Perhaps no larger than a bacterium. In that case, the Wildfire Project might be committed to destroying a highly developed life form, without ever realizing what it was doing.

This concept was not unique to Leavitt. It had been proposed by Merton at Harvard, and by Chalmers at Oxford. Chalmers, a man with a keen sense of humor, had used the example of a man looking down on a microscope slide and see in the bacteria formed into the words "Take us to your leader." Everyone thought Chalmers's idea highly amusing.

Yet Leavitt could not get it out of his mind. Because it just might turn out to be true.

Before he fell asleep, Stone thought about the conference coming up. And the business of the meteorite. He wondered what Nagy would say, or Karp, if they knew about the meteorite.

Probably, he thought, it would drive them insane. Probably it will drive us all insane.

And then he slept.

Delta sector was the designation of three rooms on Level I that contained all communications facilities for the Wildfire installation. All intercom and visual circuits between levels were routed through there, as were cables for telephone and teletype from the outside. The trunk lines to the library and the central storage unit were also regulated by delta sector.

In essence it functioned as a giant switchboard, fully computerized. The three rooms of delta sector were quiet; all that could be heard was the soft hum of spinning tape drums and the muted clicking of relays. Only one person worked here, a single man sitting at a console, surrounded by the blinking lights of the computer.
