Murray Leinster: The Ethical Equations

The Ethical Equations

BY MURRAY LEINSTER

IT IS VERY, very queer. The Ethical Equations, of course, link conduct with probability, and give mathematical proof that certain patterns of conduct increase the probability of certain kinds of coincidences. But nobody ever expected them to have any really practical effect. Elucidation of the laws of chance did not stop gambling, though it did make life insurance practical. The Ethical Equations weren’t expected to be even as useful as that. They were just theories, which seemed unlikely to affect anybody particularly. They were complicated, for one thing. They admitted that the ideal pattern of conduct for one man wasn’t the best for another. A politician, for example, has an entirely different code—and properly—than a Space Patrol man. But still, on at least one occasion—

The thing from outer space was fifteen hundred feet long, and upward of a hundred and fifty feet through at its middle section, and well over two hundred in a curious bulge like a fish’s head at its bow. There were odd, gill-like flaps just back of that bulge, too, and the whole thing looked extraordinarily like a monster, eyeless fish, floating in empty space out beyond Jupiter. But it had drifted in from somewhere beyond the sun’s gravitational field—its speed was too great for it to have a closed orbit—and it swung with a slow, inane, purposeless motion about some axis it had established within itself.

The little spacecruiser edged closer and closer. Freddy Holmes had been a pariah on the Arnina all the way out from Mars, but he clenched his hands and forgot, his misery and the ruin of his career in the excitement of looking at the thing.

“No response to signals on any frequency, sir,” said the communications officer, formally. “It is not radiating. It has a minute magnetic field. Its surface temperature is just about four degrees absolute.”

The commander of the Arnina said, “Hrrrmph!” Then he said, “We’ll lay alongside.” Then he looked at Freddy Holmes and stiffened. “No,” he said, “I believe you take over now, Mr. Holmes.”

Freddy started. He was in a very bad spot, but his excitement had made him oblivious of it for a moment. The undisguised hostility with which he was regarded by the skipper and the others on the bridge.brought it back, however.

“You take over, Mr. Holmes,” repeated the skipper bitterly. “I have orders to that effect. You originally detected this object and your uncle asked Headquarters that you be given full authority to investigate it. You have that authority. Now, what are you going to do with it?”

There was fury in his voice surpassing even the rasping dislike of the voyage out. He was a lieutenant commander and he had been instructed to take orders from a junior officer. That was bad enough. But this was humanity’s first contact with an extrasolar civilization, and Freddy Holmes, lieutenant junior grade, bad been given charge of the matter by pure political pull.

Freddy swallowed.

“I . . . I—” He swallowed again and said miserably, “Sir, I’ve tried to explain that I dislike the present set-up as much as you possibly can. I . . wish that you would let me put myself under your orders, sir, instead of—”

“No!” rasped the commander vengefully. “You are in command, Mr. Holmes. Your uncle put on political pressure to arrange it. My orders are to carry out your instructions, not to wet-nurse you if the job is too big for you to handle. This is in your lap! Will you issue orders?”

Freddy stiffened.

“Very well, sir. it’s’ plainly a ship and apparently a derelict. No crew would come in without using a drive, or allow their ship to swing about aimlessly. You will maintain your present position with relation to it. I’ll take a spaceboat and a volunteer, if you will find me one, and look ‘it over.”

He turned and left the bridge. Two minutes later he was struggling into a spacesuit when Lieutenant Bridges—also junior grade—came briskly into the spacesuit locker and observed:

“I’ve permission to go with you, Mr. Holmes.” He began to get into another spacesuit. As he pulled it up over his chest he added blithely: “I’d say this was worth the price of admission!”

Freddy did not answer. Three minutes later the little spaceboat pulled out from the side of the cruiser. Designed for expeditionary work and tool-carrying rather than as an escapecraft, it was not enclosed. It would carry men in spacesuits, with their tools and weapons, and they could breathe from its tanks instead of from their suits, and use its power and so conserve their own. But it was a strange feeling to sit within its spidery outline and see the great blank sides of the strange object draw near. When the spaceboat actually touched the vast metal wall it seemed impossible, like the approach to some sorcerer’s castle across a monstrous moat of stars.

It was real enough, though. The felted rollers touched, and Bridges grunted in satisfaction.

“Magnetic. We can anchor to it. Now what?”

“We hunt for an entrance port,” said Freddy curtly. He added: “Those openings that look like gills are the drive tubes. Their drive’s in front instead of the rear. Apparently they don’t use gyros for steering.”

The tiny craft clung to the giant’s skin, like a fly on a stranded whale. It moved slowly to the top of the rounded body, and over it, and down on the other side. Presently the cruiser came in sight again as it came up the near side once more.

“Nary a port, sir,” said Bridges blithely. “Do we cut our way in?”

“Hm-m-m,” said Freddy slowly. “We have our drive in the rear, and our control room in front. So we take on supplies amidships, and that’s where we looked. But this ship is driven from the front. Its control room might be amidships. If so, it might load at the stem. Let’s see.”

The little ctaft crawled to the stern of the monster.

“There!” said Freddy.

It was not like an entrance port on any vessel in the solar system. It slid aside, without hinges. There was an inner door, but it opened just as readily. There was no rush of air, and it was hard to tell if it was intended as an air lock or not.

“Air’s gone,” said Freddy. “It’s a derelict, all right. You might bring a blaster, but what we’ll mostly need is light, I think.”

The magnetic anchors took hold. The metal grip shoes of the spacesuits made loud noises inside the suits as the two of them pushed their way into the interior of the ship. The spacecruiser had been able to watch them, until now. Now they were gone.

The giant, enigmatic object which was so much like a blind fish in empty space floated on. It swung aimlessly about some inner axis. The thin sunlight out here beyond Jupiter, smote upon it harshly. It seemed to hang motionless in mid-space against an all-surrounding background of distant and unwinking stars. The trim Space Patrol ship hung alertly a mile and a half away. Nothing seemed to happen at all.

Freddy was rather pale when he went back to the bridge. The pressure mark on his forehead from the spacesuit helmet was still visible, and he rubbed at it abstractedly. The skipper regarded him with a sort of envious bitterness. After all, any human would envy any other who had set foot in an alien spaceship. Lieutenant Bridges followed him. For an instant there were no words. Then Bridges saluted briskly:

“Reporting back on board, sir, and returning to watch duty after permitted volunteer activity.”

The skipper touched his hat sourly. Bridges departed with crisp precision. The skipper regarded Freddy with the helpless fury of a senior officer who has been ordered to prove a junior officer a fool, and who has seen the assighment blow up in his face and that of the superior officers who ordered it.
