Isaac Asimov Quotes

Society is much more easily soothed than one's own conscience.

[A]n unpleasant nest of nasty, materialistic and aggressive people, careless of the rights of others, imperfectly democratic at home though quick to see the minor slaveries of others, and greedy without end.

I made up my mind long ago to follow one cardinal rule in all my writing—to be clear. I have given up all thought of writing poetically or symbolically or experimentally, or in any of the other modes that might (if I were good enough) get me a Pulitzer prize. I would write merely clearly and in this way establish a warm relationship between myself and my readers, and the professional critics—Well, they can do whatever they wish.

Of course there are worlds. Millions of them! Every star you see has worlds, and most of those you don't see.

There was no doubt about it: the City was the culmination of man’s mastery over the environment. Not space travel, not the fifty colonized worlds that were now so haughtily independent, but the City.

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.

Any technological advance can be dangerous. Fire was dangerous from the start, and so (even more so) was speech - and both are still dangerous to this day - but human beings would not be human without them.

Violence is the last refuge of the incompetent.
