Time—the older you get the faster it goes. - Wasp

Whenever Man was unable to master his invoice with this bare hands, thought Leeming, the said environment got bullied or coerced into submission by Man plus X. That had been so from the beginning of time—Man plus a tool or a weapon.
But X did not have to be anything concrete or solid, it did not have to be lethal or even visible. It could be a dream, an idea, an illusion, a bloody big thundering lie, just anything.
There was only one true test—whether it worked.

As for the causes, he listened to them with boredom. Only the strong know there is but one cause of war. All the other multitudinous reasons recorded in the history books were not real reasons at all. They were nothing but plausible pretexts. There was but one root-cause that persisted right back to the dim days of the jungle. When two monkeys want the same banana, that is war.

Obviously riled, he growled at Lawson, “The right to unobstructed passage covers our vessels as much as anyone else’s.”
“It covers no warship bearing instructions to intercept, question, search or detain any other spaceship it considers suspicious,” declared the other. “Violators of the law are not entitled to claim protection of the law.”
“Can you tell me how to conduct a war between systems without sending armed ships through space?” asked Markhamwit, bitterly sarcastic.
Lawson waved an indifferent hand. “We aren’t the least bit interested in that problem. It is your own worry.”
“It cannot be done,” Markhamwit shouted.
“That’s most unfortunate,” remarked Lawson, full of false sympathy. “It creates an awful state of no-war.”
“Are you trying to be funny?”
“Is peace funny?”
“War is a serious matter,” bawled Markhamwit, striving to retain a grip on his temper. “It cannot be ended with a mere flick of the finger.”
“The fact should be borne in mind by those who so nonchalantly start them,” advised Lawson, quite unmoved by the Great Lord’s ire.
“The Nileans started it.”
“They say that you did.”
“They are incorrigible liars.”
“That’s their opinion of you, too.”
A menacing expression on his face, Markhamwit said, “Do you believe them?”
“We never believe opinions.”
“You are evading my question. Somebody has to be a liar. Who do you think it is?”
“We haven’t looked into the root-causes of your dispute. It is not our woe. So without any data to go upon we can only hazard a guess.”
“Go ahead and do some hazarding then,” Markhamwit invited. He licked expectant lips.
“Probably both sides have little regard for the truth,” opined Lawson, undeterred by the other’s attitude. “It is the usual setup. When war breaks out the unmitigated liar comes into his own. His heyday lasts for the duration. After that, the victorious liars hang the vanquished ones.”
