The e-book version of Philip K. Dick's 1964 novel The Penultimate Truth contains this passage from Chapter 2:
"This is how it must feel, he thought, to contract the Bag Plague, where those virtues get in and cause your head to expand until it pops like a blown-up paper bag." Virtues? What does this mean? Virtues make your head explode? Is Dick even a good writer?
The perplexed could track down the Belmont original paperback from 1964. Dick may have been a starving hack then but at least he had editors:
This bleakly funny, proto-Cronenberg-esque image of body mayhem in the opening pages of the book sets a tone for the desperate lives of Dick's underground dwellers, crowded into shelters after a nuclear world war. Theirs is not merely a dungeon of claustrophobia and rationing but one with scary new diseases. The word "viruses" is critical and important not to flub so of course the publishers type it as "virtues." This error actually appeared in a paperback edition from 1984 and has been dutifully transcribed in every copy since. Was hoping it would be caught and fixed in the e-book but it appears that Dick's estate, the current publisher, and everyone else involved is on Dick Autopilot, slinging out his books for new generations of non-readers as some kind of empty capitalist ritual.
Here's the Belmont cover:
