The Empathy Box Symbol 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.

Empathy, he once had decided, must be limited to herbivores or anyhow omnivores who could depart from a meat diet. Because, ultimately, the emphatic gift blurred the boundaries between hunter and victim, between the successful and the defeated.

The account had a pathetic quality. A rough, cold android, hoping to undergo an experience from which, due to a deliberately built-in defect, it remained excluded. But he could not work up much concern for Roy Baty; he caught, from Dave's jottings, a repellent quality hanging about this particular android.

"No, it's that empathy," Irmgard said vigorously. Fists clenched, she roved into the kitchen, up to Isidore. "Isn't it a way of proving that humans can do something we can't do?
