“It's all true; only the facts have been changed.”

“This is a work of memory -- facts have been altered. Names have been changed.”

“Nothing that is new is ever new twice. While things that are true are still true the next time; truer, in fact, because they have been tested, they have been tasted, and they are always ripe, always ready...”

“When someone's paradigm changes, the world itself changes with it. So "facts" are only facts *for a system* or paradigm.”

“That's really what SF is all about, you know: the big reality that pervades the real world we live in: the reality of change. Science fiction is the very literature of change. In fact, it is the only such literature we have.”

“Service is the measure of greatness; it always has been true; it is true today, and it always will be true, that he is greatest who does the most of good. Nearly all of our controversies and combats grow out of the fact that we are trying to get something from each other--there will be peace when our aim is to do something for each other. The human measure of a human life is its income; the divine measure of a life is its outgo, its overflow--its contribution to the welfare of all.”
