They were the hospital’s medical elite. A diagnostician was one of those rare entities whose mind was considered stable enough to retain permanently and simultaneously up to ten physiology tapes. To their data-crammed minds was given the job of original research in xenological medicine and the diagnosis and treatment of new diseases in hitherto unknown life-forms.
There was a well-known saying in the hospital, reputed to have originated with O’Mara himself, that anyone sane enough to want to be a diagnostician was mad.
“You must understand that it is not only the physiological data that the tapes impart,” the Padre went on. “The complete memory and personality of the donor entity who possessed that knowledge is impressed as well. In effect a diagnostician subjects itself voluntarily to a most drastic form of multiple schizophrenia, with the alien personalities sharing its mind so utterly different in motivation and character that … Well, geniuses in any field are rarely nice people. These donor entities have no control over the host’s thinking or bodily functions, but a diagnostician who does not have a stable and well-integrated personality can sometimes fool itself into believing that the opposite is true and it is no longer in charge of itself. Getting used to walking on two feet when your mind insists that you have six is bad enough, but the food preferences, the dreams that come when the body is asleep and the mind has no conscious control, are much worse. Worst of all are the other-species sexual fantasies. They can be really disturbing.
“With some of the diagnosticians,” the Padre ended, “O’Mara has its hands full.”
Hewlitt thought for a moment, then said, “Now I understand the reason for Pathologist Murchison’s remark about her husband being multiply absentminded, and Prilicla’s uncertainty about detecting the virus’s emotional radiation if its host is a diagnostician, but I find it impossible to believe that…”
He broke off as another diagnostician waddled and squelched into view wearing a transparent suit with the helmet open. It was a Creppelian octopoid, Lioren said, a warm-blooded amphibious life-form who could breathe air or water. Owing to a skin condition associated with advanced age, it found it more convenient to breathe air and more comfortable to keep its body immersed in water. He did not catch its name because even through his translator it sounded like nothing so much as a short sneeze. When they agreed that it, too, had never been a virus host, Lioren spoke into its communicator.
“The last one has just gone in, Major,” it said. “With the exception of Semlic, who was invisible inside its environmental protection, all of the diagnosticians and Colonel Skempton are cleared.”
“Right, Padre,” O’Mara replied. “You two resume your search at once, and don’t waste time.”
The sound of other-species’ voices raised in anger or argument followed them as they moved away, but the sounds were too muffled for Hewlitt’s translator to make any sense of them. Lioren said, “Our next call is the AUGL ward. What is it that you find impossible to believe?”
“No offense intended,” said Hewlitt, “but I think your profession has made you feel too kindly disposed toward the chief psychologist. Nobody can convince me that he is anything but a sarcastic, bad-tempered, ill-mannered, unfeeling person who is sensitive and caring about nobody but himself. Every time he opens his mouth he reinforces that belief.”
The Padre made an untranslatable sound and said, “It is true that Major O’Mara has personality defects, and there are many people on the staff who will tell you that the only thing that keeps them sane is the fear of what O’Mara will do to them if they dare go mad. This is an exaggeration for humorous effect on their part. It is also completely untrue.”
“If you say so, Padre,” he said.
They were moving along a main corridor again. Hewlitt was avoiding other-species collisions without Lioren’s guiding hand on his shoulder and holding a conversation at the same time. He felt surprised and pleased with himself.
“Believe me,” said the Padre, “if a being of any species is in serious need of psychiatric help, there is no better person in the hospital, and that includes myself, to give it. O’Mara takes the bad cases, those which could lead to permanent mental damage or to otherwise well-motivated and dedicated members of the staff being expelled from the hospital, and more often than not it saves their sanity as well as their future careers. But those files are closed to the other psychology staff, and neither the major nor its patients will talk about the treatment they were given afterward.”
