127. "Facts are stubborn things. They cannot be altered by our wishes, our inclinations, or the dictates of our passions."
事实都是固执的。它不可能随着我们的愿望、喜好或者情绪而改变。
54. "History teaches us only one thing: knowing about the past cannot help people to make important decisions today."
历史只教会了我们一件事:了解过去无助于人们今天作出重要的决定。
202.Humans arrived in the Kaliko Islands about 7,000 years ago, and within 3,000 years most of the large mammal species that had lived in the forests of the Kaliko Islands had become extinct. Yet humans cannot have been a factor in the species' extinctions, because there is no evidence that the humans had any significant contact with the mammals. Further, archaeologists have discovered numerous sites where the bones of fish had been discarded, but they found no such areas containing the bones of large mammals, so the humans cannot have hunted the mammals. Therefore, some climate change or other environmental factor must have caused the species' extinctions.
