“When Church and State are separate, the effects are happy, and they do not at all interfere with each other; but where they have been confounded together, no tongue nor pen can fully describe the mischiefs that have ensued.”

“The concept behind personal integrity is wholeness. When a person is the same without as within, when what others know about him is the same truth he knows about himself, he has integrity.”

“The Imperial forces must keep their hands off, but they find that they can do much even so. Each sector is encouraged to be suspicious of its neighbors. Within each sector, economic and social classes are encouraged to wage a kind of war with each other. The result is that all over Trantor it is impossible for the people to take united action. Everywhere, the people would rather fight each other than make a common stand against the central tyranny and the Empire rules without having to exert force.”

“There is nothing your knife handlers can do in the way of rioting and demonstrating that will have any permanent effect as long as, in the extremity, there is an army equipped with kinetic, chemical, and neurological weapons that is willing to use them against your people. You can get all the downtrodden and even all the respectables on your side, but you must somehow win over the security forces and the Imperial army or at least seriously weaken their loyalty to the rulers.”

“I am not impressed by ancestry, since if I could trace my origins to Judas Maccabeus or to King David, that would not add one inch to my stature, either physically, mentally or ethically. What's more, what about all my other ancestors? There must have been uncounted thousands of human beings in the century of King David, all of whom in some small way contributed to my production, and every one of them but King David might have been criminals and drunkards for all I know. (Nor was King David himself entirely unremarkable for his ethical standards.)”

“I have begun to wonder where I came from. The person I am now, this fumbling, stumbling supplicant... was I built on the foundations of my old life, or did I rise from the grave a blank state? How much of me is inherited, and how much is my own creation? Questions that were once just idle musings have begun to feel strangely urgent. Am I firmly rooted to what came before? Or can I choose to deviate?”

“If I have ever made any valuable discoveries, it has been due more to patient attention, than to any other talent”
