Memory Theme Analysis

He found himself, instead, as always before, entering into the landscape of drab hill, drab sky. And at the same time he no longer witnessed the climb of the elderly man. His own feet now scraped, sought purchase, among the familiar loose stones; he felt the same old painful, irregular roughness beneath his feet and once again smelled the acrid haze of the sky — not Earth's sky but that of some place alien, distant, and yet, by means of the empathy box, instantly available.

To Eldon Rosen, who slumped morosely by the door of the room, he said, "Does she know?" Sometimes they didn't; false memories had been tried various times, generally in the mistaken idea that through them reactions to testing would be altered.
Eldon Rosen said, "No. We programmed her completely.”
“But I think toward the end she suspected." To the girl he said, "You guessed when he asked for one more try."
Pale, Rachael nodded fixedly.

Garland said, "That damn fool Resch."
"He actually doesn't know?"
"He doesn't know; he doesn't suspect; he doesn't have the slightest idea. Otherwise he couldn't live out a life as a bounty hunter, a human occupation — hardly an android occupation." Garland gestured toward Rick's briefcase. "Those other carbons, the other suspects you're supposed to test and retire. I know them all." He paused, then said, "We all came here together on the same ship from Mars. Not Resch; he stayed behind another week, receiving the synthetic memory system." He was silent, then.
Or rather it was silent.

Preoccupied, Phil Resch drove by reflex; his progressively more gloomy train of thought continued to dominate his attention. "Listen, Deckard," he said suddenly. "After we retire Luba Luft — I want you to — " His voice, husky and tormented,broke off. "You know. Give me the Boneli test or that empathy scale you have. To see about me."
"We can worry about that later," Rick said evasively. "You don't want me to take it, do you?" Phil Resch glanced at him with acute comprehension. "I guess you know what the results will be; Garland must have told you something. Facts which I don't know."

"Stories written before space travel but about space travel."
"How could there have been stories about space travel before — "
"The writers," Pris said, "made it up."
"Based on what?"
"On imagination. A lot of times they turned out wrong. For example they wrote about Venus being a jungle paradise with huge monsters and women in breastplates that glistened." She eyed him. "Does that interest you? Big women with long braided blond hair and gleaming breastplates the size of melons?"
"No," he said.

It would have been rewarding to talk to Dave, he decided. Dave would have approved what I did. But also he would have understood the other part, which I don't think even Mercer comprehends. For Mercer everything is easy, he thought, because Mercer accepts everything. Nothing is alien to him. But what I've done, he thought; that's become alien to me. In fact everything about me has become unnatural; I've become an unnatural self.

I'm a special, he thought. Something has happened to me. Like the chickenhead Isidore and his spider; what happened to him is happening to me. Did Mercer arrange it? But I'm Mercer. I arranged it; I found the toad. Found it because I see through Mercer's eyes.
