only upon those places and times where it would not endanger Reality.
The 482nd was not a comfortable Century for him. It was not like his own austere and conformist homewhen. It was an era without ethics or principles, as he was accustomed to think of such. It was hedonistic, materialistic, more than a little matriarchal. It was the only era (he checked this in the records in the most painstaking way) in which ectogenic birth flourished and, at its peak, 40 per cent of its women gave eventual birth by merely contributing a fertilized ovum to the ovaria. Marriage was made and unmade by mutual consent and was not recognized legally as anything more than a personal agreement without binding force. Union for the sake of childbearing was, of course, carefully differentiated from the social functions of marriage and was arranged on purely eugenic principles.
In a hundred ways Harlan thought the society sick and therefore hungered for a Reality Change. More than once it occurred to him that his own presence in the Century, as a man not of that time, could fork its history. If his disturbing presence could only be made disturbing enough at some key point, a different branch of possibility would become real, a branch in which millions of pleasure-seeking women would find themselves transformed into true, pure-hearted mothers. They would be in another Reality with all the memories that belonged with it, unable to tell, dream, or fancy that they had ever been anything else.
Unfortunately, to do that, he would have to step outside the bounds of the spatio-temporal chart and that was unthinkable. Even if it weren't, to step outside the bounds at random could change Reality in many possible ways. It could be made worse. Only careful analysis and Computing could properly pin-point the nature of a Reality Change.
Outwardly, whatever his private opinions, Harlan remained an Observer, and the ideal Observer was merely a set of sense-perceptive nerve patches attached to a report-writing mechanism. Between perception and report there must be no intervention of emotion.
Harlan's reports were perfection itself in that respect.
Assistant Computer Finge called him in after his second weekly report.
"I congratulate you, Observer," he said in a voice without warmth, "on the organization and clarity of your reports. But what do you really think?"
Harlan sought refuge in an expression as blank as though chipped painstakingly out of native 95th Century wood. He said, "I have no thoughts of my own in the matter."
"Oh, come. You're from the 95th and we both know what that means. Surely this Century disturbs you."
Harlan shrugged. "Does anything in my reports lead you to think that I am disturbed?"
It was near to impudence and the drumming of Finge's blunt nails upon his desk showed it. Finge said, "Answer my question."
Harlan said, "Sociologically, many facets of the Century represent an extreme. The last three Reality Changes in the aboutwhen have accentuated that. Eventually, I suppose the matter should be rectified. Extremes are never healthy."
"Then you took the trouble to check the past Realities of the Century."
"As an Observer, I must check all pertinent facts."
It was a standoff. Harlan, of course, did have the right and the duty to check those facts. Finge must know that. Every Century was continually being shaken by Reality Changes. No Observations, however painstaking, could ever stand for long without rechecking. It was standard procedure in Eternity to have every Century in a chronic state of being Observed. And to Observe properly, you must be able to present, not only the facts of the current Reality, but also of their relationship to those of previous Realities.
Yet it seemed obvious to Harlan that this was not merely unpleasantness on Finge's part, this probing of the Observer's opinions. Finge seemed definitely hostile.
At another time Finge said to Harlan (having invaded the latter's small office to bring the news), "Your reports are creating a very favorable impression with the Allwhen Council."
Harlan paused, uncertain, then mumbled, "Thank you."
"All agree that you show an uncommon degree of penetration."
"I do my best."
Finge asked suddenly, "Have you ever met Senior Computer Twissell?"
"Computer Twissell?" Harlan's eyes widened. "No, sir. Why do you ask?"
"He seems particularly interested in your reports." Finge's round cheeks drew downward sulkily and he changed the subject. "To me it seems that you have worked out a philosophy of your own, a viewpoint of history."
Temptation tugged hard at Harlan. Vanity and caution battled and the former won. "I've studied Primitive history, sir."
"Primitive history? At school?"
"Not exactly, Computer. On
