“When a traveler from the future must talk, he does not talk but whimpers. He whispers tortured sounds. He is agonized. For if he makes the slightest alteration in anything, he may destroy the future. At the same time, he is forced to witness events without being part of them, without changing them. He envies the people who live in their own time, who can act at will, oblivious of the future, ignorant of the effects of their actions. But he cannot act. He is an inert gas, a ghost, a sheet without soul. He has lost his personhood. He is an exile of time.”

“If time and the passage of events are the same, then time moves barely at all. If time and events are not the same, then it is only people who barely move. If a person holds no ambitions in this world, he suffers unknowingly. If a person holds ambitions, he suffers knowingly, but very slowly.”

“Unconditional love. That’s what he wants to give her and what he wants from her. People should give without wanting anything in return. All other giving is selfish. But he is being selfish a little, isn’t he, by wanting her to love him in return? He hopes that she loves him in return. Is it possible for a person to love without wanting love back? Is anything so pure? Or is love, by its nature, a reciprocity, like oceans and clouds, an evaporating of seawater and a replenishing of rain?”

“Who would fare better in this world of fitful time? Those who have seen the future and live only one life? Or those who have not seen the future and wait to live life? Or those who deny the future and live two lives?”

“In this world, time has three dimensions, like space. Just as an object may move in three perpendicular directions, corresponding to horizontal, vertical, and longitudinal, so an object may participate in three perpendicular futures. Each future moves in a different direction of time. Each future is real. At every point of decision, the world splits into three worlds, each with the same people, but different fates for those people. In time, there are an infinity of worlds.”

“Human beings consider themselves satisfied only compared to some other condition. A man who has owned nothing but a bicycle all of his life feels suddenly wealthy the moment he buys an automobile...But this happy sensation wears off. After a while the car becomes just another thing that he owns. Moreover, when his neighbor next door buys two cars, in an instant our man feels wretchedly poor and deprived.”

“A person who cannot imagine the future is a person who cannot contemplate the results of his actions. Some are thus paralyzed into inaction.”
