Join 📚 Hadar's Highlights
A batch of the best highlights from what Hadar's read, .
The European conquest of the world was increasingly financed through credit rather than taxes, and was increasingly directed by capitalists whose main ambition was to receive maximum returns on their investments. The empires built by bankers and merchants in frock coats and top hats defeated the empires built by kings and noblemen in gold clothes and shining armour. The mercantile empires were simply much shrewder in financing their conquests. Nobody wants to pay taxes, but everyone is happy to invest.

Indeed, there was an easy way to ascertain the distance of the transmission source. Just respond to the message, and if the other party replies quickly to the response, the Trisolarans could determine the distance based on the round-trip time and the speed of light. Or maybe they would take a really long time to reply and cause the Trisolarans to be unable to determine how long the message was en route. But the question was: Would the other party reply? Since this source had actively sent out a call into the universe, it was very likely that they would reply after getting a response from Trisolaris. And the listener was sure that the Trisolaran government had already given the order to send a message to that distant world to lure them to respond. Maybe the message had already been sent, but maybe not. If the latter was true, then the listener had a singular chance to make his own humble life glow. The listener dashed in front of the operations screen and composed a short, simple message on the computer. He directed the computer to translate the message into the same language as the message received from the Earth. Then, he pointed the listening post’s antenna in the direction the message from Earth had come from. The Transmit button was a red rectangle. The listener’s fingers hovered above it. The fate of Trisolaran civilization was now tied to these slender fingers. Without hesitation, the listener pressed the button. A high-powered radio wave carried that short message, a message that could save another civilization, into the darkness of space. Do not answer! Do not answer!! Do not answer!!!

There is some evidence that the size of the average Sapiens brain has actually decreased since the age of foraging.5 Survival in that era required superb mental abilities from everyone. When agriculture and industry came along people could increasingly rely on the skills of others for survival, and new ‘niches for imbeciles’ were opened up. You could survive and pass your unremarkable genes to the next generation by working as a water carrier or an assembly-line worker.
