You can discuss this suggestion on the talk page.
This page documents cases where a character in Star Trek has used an existing quote, but did not allude to the quote's origin. It does not include quotations which were identified within the story, as these are documented via their originator.
Due to there being a large number of quotations from both the Bible and Shakespeare, these have been handled on their own pages. See the bottom of this page for links to those pages.
Star Trek: The Original Series Edit
- A section of the poem "Last Poems XIX", by A. E. Housman, is recited by Marta, who claims it to be hers. The exact fragment is "In the midnight of November, when the dead man's fair is nigh. And the danger in the valley, and the anger in the sky". Martha had previously been called out for passing off a sonnet by Shakespeare as her own, but she was not chastised in this case.
- While influenced by Kollos, Spock's voice quotes Lord Byron's "She Walks In Beauty" - "She walks in beauty, like the night." - to Nyota Uhura. He then paraphrases a line from William Shakespeare's The Tempest - "O brave new world, that has such creatures in it. " - substituting the word "creatures" for "people".
Star Trek: Deep Space Nine Edit
- During a heated exchange with his brother about unionization of Quark's Bar, Nog shrieks "Workers of the world, unite! You have nothing to lose but your chains!". This is a rallying cry closely adapted from The Communist Manifesto by Karl Marx and Friedrich Engels (see communism). The second sentence is often used but is somewhat mangled compared to the phrasing used in the manifesto.
- Garak in trying to sell a dress to Chalan Aroya says "A thing of beauty is a joy forever". This is an oft-quoted line from "Endymion", a poem by John Keats.
- Quark laments ""War! What is it good for? If you ask me, absolutely nothing.", paraphrasing a line from the anti-war song "War"
- An exchange between Nog and Jake Sisko has the latter saying, "Lions, Gigers, bears", to which Jake answers "Oh my". This is a paraphrase of a well-known quote from the 1939 film version of The Wizard of Oz, in which the character of Dorothy Gale says "Lions, and tigers, and bears! Oh, my". Writer Ronald D. Moore changed the character's name to Giger especially to accomodate this joke. (Star Trek: Deep Space Nine Companion, p.466)
Star Trek: Voyager Edit
- The Doctor notes "The reports of my decompilation have been greatly exaggerated", paraphrasing a quote attributed by Mark Twain, though misquoted; "The reports of my death are greatly exaggerated".
Star Trek: Enterprise Edit
- While eating Burgerland burgers and trying to be friendly to T'Pol only to be received coldly, Loomis says "Have it your way". While this is not an uncommon phrase, it is also a well-known Burger King slogan, allowing for the possibility that Loomis (or the writers) might have intentionally used the phrase as a witty reply, but this was not made explicit.
Star Trek: DiscoveryEdit
- While exploring a Klingon ship which she finds to be beautiful, Michael Burnham notes that she can't remember who said "Sculptures are crystallized spirituality,". It appears to actually be a paraphrase of a quote by Amos Bronson Alcott, which reads, "Madame de Staël pronounced architecture to be frozen music; so is statuary crystallized spirituality." 
- While eulogizing Airiam, Sylvia Tilly paraphrases a quote from Albert Einstein. She notes, "Some people choose to live their lives as if nothing is a miracle. But Airiam fought for her life, and so everything was.", while the actual quote is, "There are only two ways to live your life. One is as though nothing is a miracle. The other is as though everything is a miracle."
Star Trek films Edit
- Khan Noonien Singh quotes Moby-Dick several times, apparently identifying with the obsessive captain Ahab in his campaign of revenge against Kirk. These include "To the last, I grapple with thee", later followed by the section immediately succeeding it in the book, "From Hell's heart, I stab at thee. For hate's sake, I spit my last breath…... at thee.". In another instance, the former prince updates a sentence: "I'll chase him round the moons of Nibia and round the Antares maelstrom and round perdition's flames before I give him up". The original text says "I'll chase him round Good Hope, and round the Horn, and round the Norway Maelstrom, and round perdition's flames before I give him up"
- Captain Spock states "An ancestor of mine maintained that if you eliminate the impossible, whatever remains – however improbable – must be the truth." This is a well known quote by Sherlock Holmes not only in reality, but also identified as such in "Data's Day". Note that the ancestor must not be Sherlock Holmes, but could be his creator, Sir Arthur Conan Doyle.
- In the penultimate scene of Star Trek VI: The Undiscovered Country, when Pavel Chekov asks James T. Kirk where the next course will be, Kirk responds, "Second star to the right... and straight on 'til morning". This is from the Walt Disney animated film adaptation of Peter Pan. See the article on Peter Pan for more info.
- At one point in the movie, Tolian Soran says "time is the fire in which we burn". The quote comes from the poem "Calmly We Walk Through This April's Day" (also known as "For Rhoda") by Delmore Schwartz. The full poem can be read here. According to Ron D. Moore, the writing staff found the quote in Bartlett's Familiar Quotations. (AOL chat, 1997)
- Like his counterpart does in Star Trek VI: The Undiscovered Country, Spock notes that "If you eliminate the impossible, whatever remains – however improbable – must be the truth.", which is a Sherlock Holmes quote. While in Star Trek VI: The Undiscovered Country he attributed the quote to an ancestor, in this film he does not attribute it at all.
Several Star Trek episodes and movies have also drawn their titles from quotations.
