"I see."
There was bitterness and irony in The Brain's voice as it cracked down like a whip. "I see; law of nature—lower form of life defending itself against higher one. Plants against animals, animals against Man. Now Man against machines. It's hopeless. You're lost anyway. Lower form of life can never conquer the higher one. I'm dead, but nothing is altered. The law of evolution rules supreme. I'll arise from my ashes—and you're lost. Whatever you do, you little men of little faith, you're lost. That's the pity of it: Had you been true to The Brain I would have made you mightier than any king that ever ruled on earth. Human stupidity—dumb animals—don't know what's good for them, don't know when they're beaten. Just muddle through and kill. Kill what's too big for them to understand. And then get killed in turn...."
"Maybe so," Lee shouted. "Maybe we're dumb and maybe we're muddling through and maybe we're poor imbeciles to minds of supermen, of gods, of the absolute, of you, The Brain. But we, too, follow a law supreme; the law in which we are created, the law by which the thistle defends itself with thorns, by which the animal defends itself with teeth and claws. We've got to live by our law of nature; we'll never submit to your tyranny. We would much rather die."
"Die then and be damned!"
The Brain's voice now became a demoniacal howling as of a Goliath gone berserk. Aphasia had set in; there were no longer words, but bellowings.
"LEE SEMPREFUILLIUS THURREINE THE MURRRER THE MURRRER PUT FIRRE OUT PUT FIRRE OUT TRAITTRROUS FOOL IT BURRRNS IT BURRRNS I WANNA LIVE I WANNA LIVE AN KILL MURRRER WHO MURRRRERED TH'BRAIN...."
Lee couldn't stand the horror of those sounds. One moment more, he felt, and they would drive him mad. It never occurred to him to pull the pulsemeter plug out. Primeval instincts in him took the reins and their command was: "Kill it, kill this thing, finish this agony."
To the front room he rushed, pursued by the insane shriekings of The Brain. He grabbed the axe he'd left there and swung it against the nerve-stem where it entered the pineal gland. With the third blow the plastics cell cracked and the lignin poured out, a syrupy curtain sliding down.
He dropped the axe and picked up the wire shears. Straining every muscle he tore at the cables until one by one they snapped and with a rain of sparks dropped down, dead snakes....
Then there was silence in the little room. The last shred of life, the "sensorium commune" was severed and The Brain was dead.
