“You’ve downloaded this information,” Cromwell said briskly, “so let’s make sure you understand it. We’ve been examining the evolution of combat, weaponry, and tactics. History has shown one simple fact: people are people. Period. All the technology and progress in the world can’t change the fundamentals of human nature. There will always be war as long as human beings are capable of envy, hatred, and fear.”

“The question of whether world peace will ever be possible can only be answered by someone familiar with world history. To be familiar with world history means, however, to know human beings as they have been and always will be. There is a vast difference, which most people will never comprehend, between viewing future history as it will be and viewing it as one might like it to be.

For though to-day is always to-day and the moment is always modern, we are the only men in all history who fell back upon bragging about the mere fact that to-day is not yesterday. I fear that some in the future will explain it by saying that we had precious little else to brag about. For, whatever the medieval faults, they went with one merit. Medieval people never worried about being medieval; and modern people do worry horribly about being modern.”
