19. “When you learn it somewhere, you hear it everywhere” is an example of another Greek rhetorical structure, chiasmus, which is like antimetabole but plays by looser rules. It’s still structurally symmetrical, but you don’t have to invert the exact same words. Kennedy’s inaugural address begins with an orgy of chiasmus: “We observe today not a victory of party but a celebration of freedom—symbolizing an end as well as a beginning—signifying renewal as well as change.” If you removed all the chiasmus and antimetabole from Kennedy’s most famous speech, you’d be left with a list of conjunctions.
