The average human, on the other hand, thinks about all sorts of things around the clock, on all sorts of levels, with interruptions from dozens of biological calendars and time-pieces. There’s thoughts about to be said, and private thoughts, and real thoughts, and thoughts about thoughts, and a whole gamut of subconscious thoughts. To a telepath the human head is a din. It is a railway terminus with all the Tannoys talking at once. It is a complete FM waveband—and some of those stations aren’t reputable, they’re outlawed pirates on forbidden seas who play late-night records with limbic lyrics.
