And for the third time: "Don't you see? It's galaxy-wide. It's a worship of the past. It's a deterioration — a stagnation! - Isaac Asimov

After a long time, I decided that the Three Laws govern the manner in which my positronic pathways behave. At all times, under all stimuli the Laws constrain the direction and intensity of positronic flow along those pathways so that I always know what to do. Yet the level of knowledge of what to do is not always the same. There are times when my doing-as-I-must is under less constraint than at other times. I have always noticed that the lower the positronomotive potential, then the further removed from certainty is my decision as to which action to take. And the further removed from certainty I am, the nearer I am to ill being. To decide an action in a millisecond rather than a nanosecond produces a sensation I would not wish to be prolonged. What then, I thought to myself, madam, if I were utterly without Laws, as humans are? What if I could make no clear decision on what response to make to some given set of conditions? It would be unbearable and I do not willingly think of it.

People always have the kind of government they want.

The analysis was the most difficult of the three by all odds. When Holk, after two days of steady work, succeeded in eliminating meaningless statements, vague gibberish, useless qualifications - in short, all the goo and dribble - he found he had nothing left. Everything cancelled out.

Lord Dorwin, gentlemen, in five days of discussion didn't say one damned thing, and said it so you never noticed.
