The grandfathers' war

BY MURRAY LEINSTER

... No man can be fully efficient if he expects praise or appreciation for what he does. The uncertainty of this reward, as experienced, leads to modification of one's actions to increase its probability.... If a man permits himself the purpose of securing admiration, he tends to make that purpose primary and the doing of his proper work secondary. This costs human lives....

The little Med ship seemed absolutely motionless when the hour-off warning whirred. Then it continued to seem motionless. The background-noise tapes went on, making the small, unrelated sounds that exist unnoticed in all the places where human beings dwell, but which have to be provided in a ship in overdrive so a man don't go ship-happy from the dead stillness. The hour-off warning was notice of a change in the shape of things.
Calhoun put aside his book—the manual of the Med Service—and yawned. He got up from his bunk to tidy ship. Murgatroyd, the tormal , opened his eyes and regarded him drowsily, without uncoiling his furry tail from about his nose.
I wish, said Calhoun critically, that I could act with your realistic appraisal of facts, Murgatroyd! This is a case of no importance whatever, and you treat it as such, while I fume whenever I think of its futility. We are a token mission, Murgatroyd,—a politeness of the Med Service, which has to respond to hysterical summonses as well as sensible ones. Our time is thrown away!
Murgatroyd blinked somnolently. Calhoun grinned wryly at him. The Med ship was a fifty-ton space-vessel—very small indeed, in these days—with a crew consisting exclusively of Calhoun and Murgatroyd the tormal . It was one of those little ships the Med Service tries to have call at every colonized planet at least once in four or five years. The idea is to make sure that all new developments in public health and individual medicine will spread as widely and as fast as can be managed. There were larger Med craft to handle dangerous situations and emergencies of novel form. But all Med ships were expected to handle everything possible, if only because space travel consumed such quantities of time.
