“Old men tend to forget what thought was like in their youth; they forget the quickness of the mental jump, the daring of the youthful intuition, the agility of the fresh insight. They become accustomed to the more plodding varieties of reason, and because this is more than made up by the accumulation of experience, old men think themselves wiser than the young.”
― Isaac Asimov, Pebble in the Sky

“Every period of human development has had its own particular type of human conflict—its own variety of problem that, apparently, could be settled only by force. And each time, frustratingly enough, force never really settled the problem. Instead, it persisted through a series of conflicts, then vanished of itself—what's the expression—ah, yes, 'not with a bang, but a whimper,' as the economic and social environment changed. And then, new problems, and a new series of wars.”
― Isaac Asimov, I, Robot

“If you're born in a cubicle and grow up in a corridor, and work in a cell, and vacation in a crowded sun-room, then coming up into the open with nothing but sky over you might just give you a nervous breakdown.”
― Isaac Asimov, Foundation

“It is change, continuing change, inevitable change, that is the dominant factor in society today. No sensible decision can be made any longer without taking into account not only the world as it is, but the world as it will be...
  This, in turn, means that our statesmen, our businessmen, our everyman must take on a science fictional way of thinking.”
― Isaac Asimov, Asimov on Science Fiction
