Arthur C. Clarke: 1917-2008
[Economist] Did Sir Arthur believe in extra-terrestrials? The answer was given with a smile. “Two possibilities exist: either we are alone in the universe or we are not. Both are equally terrifying.” And UFOs? A broader smile. “They tell us absolutely nothing about intelligence elsewhere in the universe, but they do prove how rare it is on Earth.” For all his star-gazing, Sir Arthur’s feet were firmly on the ground.
