damn with faint praise

Compliment so feebly that it amounts to no compliment at all, or even implies condemnation. For example, The reviewer damned the singer with faint praise, admiring her dress but not mentioning her voice . This idea was already expressed in Roman times by Favorinus (c. a.d. 110) but the actual expression comes from Alexander Pope's Epistle to Doctor Arbuthnot (1733): "Damn with faint praise, assent with civil leer, and, without sneering, teach the rest to sneer."

damn with faint praise, to

To compliment so slightly that it amounts to no compliment at all, or even the reverse, a condemnation. The Roman writer Favorinus said, about a.d. 110, that it is more shameful to be praised faintly and coldly than to be censured violently. The practice was taken up early on, especially by literary critics. The classic quotation is from Alexander Pope’s Epistle to Dr. Arbuthnot (1733). In poking fun at the critic Joseph Addison, here called Atticus, Pope said he would “Damn with faint praise, assent with civil leer, and, without sneering, teach the rest to sneer.” See also left-handed compliment.
