 By contrast, in other cases, even very simple ones, it is controversial exactly what inferences intensional transitives in unspecific readings support. If Mary seeks a man who has read Proust, does it follow that she seeks a man who can read? After all, it is unlikely that a comic-book reader will satisfy her tastes in  men.[10]  If Perseus seeks a mortal gorgon, does it follow that he seeks a  gorgon?[11]  After all, if he finds an immortal gorgon, he is in trouble. Zimmerman (1993, 173) takes it to be a requirement on accounts of notional readings that they validate these deletion or “weakening” inferences. But there are characterizations of unspecific readings on which these inferences are in fact invalid, for instance, a characterization in terms of indifference towards which object of the relevant kind is found (Lewis uses such an ‘any one would do’ characterization in Lewis 1972, p. 199). For even if it is true that Mary seeks a man who has read Proust, and any male Proust-reader would do, it does not follow that Mary seeks a man who can read, and any man who can read would do. For not every man who can read has read Proust.
