Henry Kuttner, The power and the glory (1947)
“ No single mind could withstand the doubled strength of that split brain dragging him down to madness. . . .And then, suddenly, he was not fighting alone. Out of the darkness Llesi’s mind came swiftly, intangibly, yet with a strength as if the man himself had set his shoulder against Miller’s, bracing him against the whirlpool whose vortex led down to insanity.Perhaps no other mind in existence could have stood against the riven mind of Brann-Tsi. But in Miller’s brain too a double mind had been housed—his own and Llesi’s. They had learned to work together. And now they could fight. ”
