“Fancies were all very well for a change, but must be only occasional guests in a world devoted to reality.”

“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.”

“Our relation, all round, exists--it's a reality, and a very good one; we're mixed up, so to speak, and it's too late to change it. We must live IN it and with it”

“I imagine there must be only a very, very few men in the world, that I should like to marry; and of those few, it is ten to one I may never be acquainted with one; or if I should, it is twenty to one he may not happen to be single, or to take a fancy to me.”

“I searched everywhere for a proof of reality, when all the while I understood quite well that the standard of reality had changed”

“The private experience that you perceive forms your world, period. But which world do you inhabit? For if you altered your private sensations of reality, then that world, seemingly the only one, would also change. You do go through transformations of beliefs all the time, and your perception of the world is different. You seem to be, no longer, the person you that you were. You are quite correct — you are not the person that you were, and your world has changed, and not just symbolically.”
