The new knowledge was not hoarded, was not held under jealous guard by those who had given it, but by those to whom it had been given. One man from another; one group of men from another. States and nations from each other.
Until there was no trust left on all the planet.
There were the wars, then.
And when they were over, the new masters had established their first beachhead in the new System.
"But, it was only a beachhead, and had been only intended as such—" The pictures broke off; the unspoken words resumed. "Your planet was the ultimate target, but at first, your civilization was not adequately advanced to fall prey to their technique. Their weapon is knowledge, but the potentialities of that knowledge must be understood by a people before it can be effectively used to destroy them.
"The rest must be self-evident. After we destroyed ourselves, they sank their infectious, hollow roots into our planet. And from then, investigated your Earth from time to time ... and waited....
"Waited, because they knew you would be coming. And they knew what kind of men you would be. Strong men, with the light of the stars in your eyes. Yet confused, weak men, with the darkness of suspicion and jealousy still in your souls. Such are humans, after all....
"That is why we stopped you, Johnny Love. Once your blast-off ogee had carried you beyond the curvature of their horizon and brought you over us, our psibeam was effective and theirs were not. We are sorry about your ship. Once they realize that you were under our influence, and were returning rather than taking their precious data to your people, they zeroed-in with those damnable guided juggernauts—"
"It wasn't you, then. You mean they—"
"There is little that they cannot do. Destruction is their forte. They could not keep us from preventing your taking their 'gift' to your people, but they could keep that 'gift' from falling into our hands—and they did. They do not always win. But they never lose."
