The professor walked around to the table and poured a glass of Coke. The silence of the room slowly dissolved into a rising tide of voices. One by one, the statues that had been listening returned to life. Danchekker took a long drink and stood in silence for a while, contemplating his glass. Then he turned to face the room again.

"Suddenly lots of things that we have always simply taken for granted start falling into place." Attention centralized on him once again. "Have you ever stopped to think what it is that makes man so different from all the other animals on Earth? I know that we have larger brains, more versatile hands, and so forth; what I am referring to is something else. Most animals, when in a hopeless situation will resign themselves to fate and perish in ignominy. Man, on the other hand, does not know how to give in. He is capable of summoning up reserves of stubbornness and resilience that are without parallel on his planet. He is able to attack anything that threatens his survival, with an aggressiveness the like of which the Earth has never seen otherwise. It is this that has enabled him to sweep all before him, made him lord of all the beasts, helped him tame the winds, the rivers, the tides, and even the power of the Sun itself. This stubbornness has conquered the oceans, the skies, and the challenges of space, and at times has resulted in some of the most violent and bloodstained periods in his history. But without this side to his nature, man would be as helpless as the cattle in the field."

Danchekker scanned the faces challengingly. "Well, where did it come from? It seems out of character with the sedate and easygoing pattern of evolution on Earth. Now we see where it came from: It appeared as a mutation among the evolving primates that were isolated on Minerva. It was transmitted through the population there until it became a racial characteristic. It proved to be such a devastating weapon in the survival struggle there that effective opposition ceased to exist. The inner driving force that it produced was such that the Lunarians were flying spaceships while their contemporaries on Earth were still playing with pieces of stone.

"That same driving force we see in man today. Man has proved invincible in every challenge that the Universe has thrown at him. Perhaps this force has been diluted somewhat in the time that has elapsed since it first appeared on Minerva; we reached the brink of that same precipice of self-destruction but stepped back. The Lunarians hurled themselves in regardless. It could be that this was why they did not seek a solution by cooperation—their in-built tendency to violence made them simply incapable of conceiving such a formula.
