Perhaps the most striking aspect of this entire subject is that there are nonhuman primates so close to the edge of language, so willing to learn, so entirely competent in its use and inventive in its application once the language is taught. But this raises a curious question: Why are they all on the edge? Why are there no nonhuman primates with an existing complex gestural language? One possible answer, it seems to me, is that humans have systematically exterminated those other primates who displayed signs of intelligence.

"It is conventional wisdom now that anything built by the government will be a disaster. But the two "Voyager" spacecraft were built by the government (in partnership with that other bugaboo, academia). They came in at cost, on time, and vastly exceeded their design specifications — as well as the fondest dreams of their makers. Seeking not to control, threaten, wound, or destroy, these elegant machines represented the exploratory part of our nature set free to roam the Solar System and beyond. This kind of technology, the treasures it uncovers freely available to all humans everywhere, has been, over the last few decades, one of the few activities of the United States admired as much by those who abhor many of its policies as by those who agree with it on every issue. "Voyager" cost each American less than a penny a year from launch to Neptune encounter. Missions to the planets are one of those things — and I mean this not just for the United States, but for the human species — that we do best."
