Things base and vile, folding no quantity,
Love can transpose to form and dignity (I i 232-3)
These lines of Helena's form an aphorism, that is "the pithy and pointed statement of a serious maxim, opinion or general truth." (Abrams 1993: 219) A Midsummer Night's Dream has many examples of aphorisms. As Harold Brooks points out: "Theseus' wisdom often takes aphoristic form, and even Bottom has his "reason and love keep little company together nowadays. The more the pity, that some honest neighbours will not make them friends." (III i 138-141) (Brooks 1983: xlviii)
Other rhetorical figures are used frequently in the play, such as antitheses, conceits, stichomythia, and many more. See Brooks 1983: xlv-l for examples.
