"These creatures are among us, although morphologically they do not differ from us; we must not posit a difference of essence, but a difference of behavior. In my science fiction I write about about them constantly. Sometimes they themselves do not know they are androids. Like Rachel Rosen, they can be pretty but somehow lack something; or, like Pris in We Can Build You, they can be absolutely born of a human womb and even design androids — the Abraham Lincoln one in that book — and themselves be without warmth; they then fall within the clinical entity "schizoid," which means lacking proper feeling. I am sure we mean the same thing here, with the emphasis on the word "thing." A human being without the proper empathy or feeling is the same as an android built so as to lack it, either by design or mistake. We mean, basically, someone who does not care about the fate which his fellow living creatures fall victim to; he stands detached, a spectator, acting out by his indifference John Donne's theorem that "No man is an island," but giving that theorem a twist: that which is a mental and a moral island is not a man."

“Crazy people do not apply the principle of scientific parsimony... they shoot for the baroque.”

“You don't go by odds. You know what's coming. You've seen the cards already." She studied his face intently. "No, you can't be cold-decked. It wouldn't be possible.”

“told us about our own world. This, what's around us now. He wants us to see it for what it is. And I do, and more so each moment.”

“Silence. It flashed from the woodwork and the walls; it smote him with an awful, total power, as if generated by a vast mill. It rose from the floor, up out of the tattered gray wall-to-wall carpeting. It unleashed itself from the broken and semi-broken appliances in the kitchen, the dead machines which hadn’t worked in all the time Isidore had lived here. From the useless pole lamp in the living room it oozed out, meshing with the empty and wordless descent of itself from the fly-specked ceiling. It managed in fact to emerge from every object within his range of vision, as if it—the silence—meant to supplant all things tangible. Hence it assailed not only his ears but his eyes; as he stood by the inert TV set he experienced the silence as visible and, in its own way, alive. Alive! He had often felt its austere approach before; when it came it burst in without subtlety, evidently unable to wait. The silence of the world could not rein back its greed. Not any longer. Not when it had virtually won.”

“We do not have an ideal world, such as we would like, where morality is easy because cognition is easy. Where one can do right with no effort because he can detect the obvious.”

“Barefoot conducts his seminars on his houseboat in Sausalito. It costs a hundred dollars to find out why we are on this Earth. You also get a sandwich, but I wasn't hungry that day. John Lennon had just been killed and I think I know why we are on this Earth; it's to find out that what you love the most will be taken away from you, probably due to an error in high places rather than by design.”
