An old, widely used phrase expressing the sentiment that revenge that is delayed, and executed well after the heat of anger has dissipated, is more satisfying than revenge taken as an immediate act of rage.
It has been frequently been claimed on
the Internet to have
originated in the novel "Les Liaisons Dangereuses" by Pierre Choderlos de Laclos. In truth, however, there are two problems with the widely circulated quotation from that book. The first is that the phrase does not appear in the novel, or
anything else that de Lacois wrote. The second problem is that the French quotation used as proof is linguistically erroneous; de Lacois would never have written the words attributed to him. Thus it bears all the hallmarks of an Internet "fact" for which someone invented an authentication that seemed plausible, knowing that it would rarely be verified.
The phrase has been in use since at least the 19th century, and at least one author's use of it back then expressed to the reader that it was an already existing dictum.
Of course, how long ago it came into being in the Klingon Empire would be an
interesting subject for xenolinguistic research.
