Now, motivational patterns are going to be similar among all espionage agents. That is to say: there will be certain types of motivation that are similar despite differing schools or opposed aims. You will study first how to separate this element for your analysis — in the beginning, through interrogation patterns that betray the inner orientation of the interrogators; secondly, by close observation of language-thought orientation of those under analysis. You will find it fairly simple to determine the root languages of your subjects, of course, both through voice inflection and speech pattern.

Limits of survival are set by climate, those long drifts of change which a generation may fail to notice. And it is the extremes of climate which set the pattern. Lonely, finite humans may observe climatic provinces, fluctuations of annual weather and, occasionally may observe such things as “This is a colder year than I’ve ever known.” Such things are sensible. But humans are seldom alerted to the shifting average through a great span of years. And it is precisely in this alerting that humans learn how to survive on any planet. They must learn climate.
