"Five exclamation marks, the sure sign of an insane mind"
About this Quote
The line works because it’s a tiny, weaponized rule of taste masquerading as a diagnosis. Calling it “the sure sign of an insane mind” is knowingly outrageous, a satirical overreach that mirrors the very excess it condemns. Pratchett is policing the border between wit and noise, but he does it with a wink: the insult is so exaggerated that it becomes a parody of judgmental literary snobbery even as it indulges in it.
Context matters. Pratchett wrote in the shadow of British comic tradition and newsroom-style minimalism, where the exclamation mark is treated like hot sauce: potent, easy to overuse, embarrassing when sloshed everywhere. It’s also a pre-internet prophecy. Before caps lock and reaction GIFs, the exclamation mark was the mass-market tool for manufactured excitement, a hallmark of breathless advertising copy and melodramatic prose. Pratchett’s subtext: if your words can’t carry the emotion, no amount of typographical screaming will save them. The real sanity test isn’t punctuation; it’s restraint.

| Source | Evidence: Five exclamation marks, the sure sign of an insane mind. (Page 189 (reported in APF; pagination varies by edition)). Primary source appears to be Terry Pratchett’s Discworld novel Reaper Man (first published in the UK by Victor Gollancz on 23 May 1991). The quote is widely attributed to Reaper Man, and L-Space’s Annotated Pratchett File specifically states it occurs in Reaper Man on p. 189 (but page numbers vary by edition/format). Colin Smythe’s bibliographic page confirms the 1991 Gollancz first hardback publication and gives the ISBN 0-575-04979-0 for that edition; many later paperback/US editions have different pagination and ISBNs.
