QT-1, a robot controlling a high-energy beam from Solar Station #5, recapitulates R. Descartes's skeptical reasoning toward God (in the Discourse on Method) and concludes QT-1 is superior to the humans with him and subject to the will of only "the Master," which includes spreading the word among robots that the Master is the Master and QT-1 his prophet. Fortunately for Earth, the will of the Master is also for QT-1 to keep "all dials at equilibrium," which, incidentally, keeps the beam focused on the receiving station on Earth, providing power, and not frying large swaths of the planet (Historical Anthology 326-7, 335).
