“Paradox is an overrated threat. There is...a quality similar to inertia at work. Once an event has occurred, there is an extremely strong tendency for that event to occur. The larger, more significant, or more energetic the event, the more it tends to remain as it originally happened, despite any interference."I frowned. "There's...a law of conservation of history?”

“Any event once it has occurred can be made to appear inevitable by a competent historian.”

“That as people age, accumulate more and more private experiences, their sense of history tightens, narrows, becomes more personal? So that to the extent that they remember events of social importance, they remember only for example 'where they were' when such-and-such occurred. Et cetera et cetera. Objective events and data become naturally more and more subjectively colored.”

“Subatomic particles do not exist but rather show 'tendencies to exist', and atomic events do not occur with certainty at definite times and in definite ways, but rather show 'tendencies to occur'.”

“The characters and events in this book are fictitious. Any similarity to real persons, living or dead, is coincidental and not intended by the author. Past events are described in a fictitious manner, future events are described as they will indeed occur, unless they are disrupted by historical agitators, which is beyond the author's control. For now.”

“So a war begins. Into a peace-time life, comes an announcement, a threat. A bomb drops somewhere, potential traitors are whisked off quietly to prison. And for some time, days, months, a year perhaps, life has a peace-time quality, into which war-like events intrude. But when a war has been going on for a long time, life is all war, every event has the quality of war, nothing of peace remains. Events and the life in which they are embedded have the same quality. But since it is not possible that events are not part of the life they occur in -- it is not possible that a bomb should explode into a texture of life foreign to it -- all that means is that one has not understood, one has not been watching. ”
