its works are gradually degraded to the lowest level of meaning and creativity." "But why?" The Explorer sounded anguished. "Why should any intelligent species end like that? I grant the possibility of atomic power getting out of hand, though one would have thought they'd have taken the greatest precautions. Still, it could happen. But that fourth answer—it's morbid." "Cultures and civilizations die," said the Archeologist evenly. "That has happened repeatedly in our own history. Why not species? An individual dies—and is there anything intrinsically more terrible in the death of a species than in the death of an individual?" He paused. "With respect to the members of this one species, I think that a certain temperamental instability hastened their end. Their appetites and emotions were not sufficiently subordinated to their understanding and to their sense of drama—their enjoyment of the comedy and tragedy of existence. They were impatient and easily incapacitated by frustration. They seem to have been singularly guilty in their pleasures, behaving either like gloomy moralists or gluttons.

They set great store by personal prestige, by the amassing of wealth and the exercise of power. Their notable capacity for thought and manipulative activity was expended on things rather than persons or feelings. Their technology outstripped their psychology. They skimped fatally when it came to hard thinking about the purpose of life and intellectual activity, and the means for preserving them." Again the slow shadows drifted overhead.

The Explorer turned away. His excitement had visibly evaporated, leaving behind a cold and miserable residue of feeling. "I am not sure I want to hear much more about them," he said. "They sound too
