A guided missile corrects its trajectory as it flies, homing in, say, on the heat of a jet plane's exhaust. A great improvement on a simple ballistic shell, it still cannot discriminate particular targets. It could not zero in on a designated New York skyscraper if launched from as far away as Boston.
From the smallest necessity to the highest religious abstraction, from the wheel to the skyscraper, everything we are and everything we have comes from one attribute of man - the function of his reasoning mind.
I find television, and particularly live television, very romantic: the idea that there is this small group of people, way up high, in a skyscraper in the middle of Manhattan, beaming this signal out into the night.
