Orr’s ragged state reflects the inadequacy of his attempt to control his dreams by suppressing them: if he looks so awful after only a few days, it’s clear that he can’t go on this way forever. Heather’s comparison of Orr to “a block of wood not carved” is an allusion to the novel’s title, since a
lathe is a machine that can be used to carve materials like wood. It’s also likely an allusion to the Taoist principle of
P’u or “the uncarved block,” a reference to a thing’s natural state of simplicity. Heather likens Orr to a solid block of material not yet shaped and diminished by the powerful force of the lathe. In emphasizing Orr’s “wholeness,” Heather suggests that escaping Haber’s manipulative influence restores Orr’s inner balance.
