the head as the only place a self occurs — "The human head, sir, if I…"

Schtitt's drill-yard sermon locates the player not in the body but "in the mind," and Hal completes it: the head is "where I'm going to occur," the sole venue the self takes place in — you are not arms. The striking half is his coda, "the game's two heads' one world," which floats the possibility that two sealed skulls might, inside the lines, briefly share one world; the whole book's ache is whether that shared world is real contact or just two solipsisms volleying. (The second-world doctrine itself stays the-body-tennis's.) [sweep · shared-ground the-body-tennis]
