"Here, the enemy was not merely another group of human beings with a differing political persuasion; the enemy here was death."

“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.”

“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!

"It is custom which rules," Hume said, and in that one sentence undermined both science and philosophy.”
