The average ground temperature of the Earth is impossible to measure since most of the Earth is ocean...So this average ground temperature is a fiction.
Freeman DysonThe more I examine the universe and study the details of its architecture, the more evidence I find that the universe in some sense must have known that we were coming.
Freeman DysonIntelligence may indeed be a benign influence creating isolated groups of philosopher-kings far apart in the heavens... On the other hand, intelligence may be a cancer of purposeless technological exploitation, sweeping across a galaxy as irresistibly as it has swept across our own planet.
Freeman DysonIf we had a reliable way to label our toys good and bad, it would be easy to regulate technology wisely. But we can rarely see far enough ahead to know which road leads to damnation. Whoever concerns himself with big technology, either to push it forward or to stop it, is gambling in human lives.
