Poetry and consumption are the most flattering of diseases.

Shenstone’s epigram hinges on an 18th‑century cultural association: both writing poetry and suffering from “consumption” (tuberculosis) could be perversely romanticized. To call them “flattering” is to suggest they confer a kind of aesthetic or social prestige—poetry as a mark of refined sensibility, consumption as a disease thought to lend sufferers a delicate, interesting appearance and an aura of heightened feeling. The line is satirical: it punctures the vanity that can attach to artistic self-image and to fashionable illness, implying that both can become poses that invite admiration rather than sober judgment.
