"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 every man must take on a science fictional way of thinking."
"Suppose that we are wise enough to learn and know -- and yet not wise enough to control our learning and knowledge, so that we use it to destroy ourselves? Even if that is so, knowledge remains better than ignorance. It is better to know -- even if the knowledge endures only for the moment that comes before destruction -- than to gain eternal life at the price of a dull and swinish lack of comprehension of a universe that swirls unseen before us in all its wonder. That was the choice of Achilles, and it is mine, too."
"The important thing is not to stop questioning. Curiosity has its own reason for existing. One cannot help but be in awe when he contemplates the mysteries of eternity, of life, of the marvelous structure of reality. It is enough if one tries merely to comprehend a little of this mystery everyday. Never lose a holy curiosity."
"It might sound a paradoxical thing to say --for surely never has a generation of children occupied more sheer hours of parental time --but the truth is that we neglected you. We allowed you a charade of trivial freedoms in order to avoid making those impositions on you that are in the end both the training ground and proving ground for true independence. We pronounced you strong when you were still weak in order to avoid the struggles with you that would have fed your true strength. We proclaimed you sound when you were foolish in order to avoid taking part in the long, slow, slogging effort that is the only route to genuine maturity of mind and feeling. Thus, it was no small anomaly of your growing up that while you were the most indulged generation, you were also in many ways the most abandoned to your own meager devices by those into whose safe-keeping you had been given."
