4->''"I live by syllogisms: God is love. Love is blind. Stevie Wonder is blind. Therefore, Stevie Wonder is God. I don't know what I'd believe in if it wasn't for that."''
5-->-- '''Creator/StephenColbert''', ''Series/TheColbertReport''

7Also called the Politician's Syllogism or [[http://en.wikipedia.org/wiki/Equivocation Equivocation]].
8
9A standard three-step syllogism uses three terms -- the things that are being linked by the line of reasoning. If A, then B. If B, then C. Therefore if A, then C. The fallacy of four terms occurs when, [[ExactlyWhatItSaysOnTheTin exactly like it says]], ''four'' terms are used instead of three. In most cases, a single term (B) is used two (or more) times, in differing contexts with different meanings; and yet the argument treats the two usages as exactly the same, since the same term was used.
10
11It's best explained by this example from ''Film/LandOfTheBlind.''
12
13->A dry crust of bread is better than nothing\
14But nothing is better than a big juicy steak.\
15Therefore, [[InsaneTrollLogic a dry crust of bread is better than a big juicy steak]].
16
17This uses two different meanings of the word "nothing." The first line uses "nothing" to mean "a lack of food", while the second line uses "nothing" as "no such thing exists."
18
19This fallacy can often be the core of a joke or pun, such as if someone were to suggest that Franchise/{{Batman}} must be good at baseball, since he's so well-acquainted with bats.

26[[folder:Advertising]]
27* [=Hu-Hot=] Mongolian Grill used this fallacy in a comic radio ad promoting their new "to-go" service, aired in mid 2017. The two people speaking are a museum guard and a woman eating a Hu-Hot To-Go Meal. He tells her that she can't eat that here (in the museum). She replies that certainly she can, it's designed to be eaten anywhere. He repeats that she can't eat it in the museum, adding that there's a "no-food policy". She again asserts that she not only ''can'' eat it there, she ''is'' eating it there. The term that's doubled-up is "can". The guard is using it in the sense of "allowed or permitted", the woman is using it in the sense of "capable of".
28* Anadin pain pills used to be marketed with the slogan "Nothing acts faster than Anadin", prompting the zinger "So take nothing -- it's cheaper".

31[[folder:Comedy]]
32* Comedian Creator/RichardJeni talks about when he learned about the syllogism in college in his ''Crazy from the Heat'' stand-up routine. God is love. Love is blind. Therefore, Music/RayCharles is God.
33[[/folder]]
34
35[[folder:Comic Strips]]
36* ComicStrip/{{Garfield}} expresses the philosophy. "If nobody is perfect, I must be nobody."
37[[/folder]]
38
39[[folder:Film]]
40* In the Creator/WoodyAllen film ''Film/LoveAndDeath'', Allen's character Boris gives this monologue: "What would Socrates say? All those Greeks were homosexuals. Boy, they must have had some wild parties. I bet they all took a house together in Crete for the summer. A: Socrates is a man. B: All men are mortal. C: All men are Socrates. That means all men are homosexuals."
41[[/folder]]
42
43[[folder:Jokes]]
44* There's an old joke revolving around the word ''nothing'', where a bar patron turns down a beer from the bartender because "nothing is better than a cold drink".
45** Related is "There is nothing like a good cup of coffee... and this is nothing like a good cup of coffee."
46** Also, "Nothing is better than eternal paradise. A ham sandwich is better than nothing. So a ham sandwich is better than eternal paradise."
47* An old joke: When you drink, you get drunk. When you get drunk, you go to sleep. When you go to sleep, you commit no sin. When you commit no sin, you go to {{Heaven}}. So, let's all get drunk and go to Heaven!
48** Another similar drinking joke: The more I drink, the more my hands shake. The more my hands shake, the more drink I spill. The more drink I spill, the less I drink. [[LogicBomb Therefore, the more I drink, the less I drink.]]
49* A school joke:
50-->'''Student:''' "You wouldn't punish me for something I didn't do, would you?" \
51'''Teacher:''' "Of course I wouldn't." \
52'''Student:''' "Good, because I didn't do my homework!"
53* A cat has three tails. No cat has two tails, and one cat has one more tail than no cat; therefore, one cat has three tails.
54* Two versions of {{Fauxtivational Poster}}s in places of education:
55** One version:
56-->Knowledge is power.\
57Power corrupts.\
58Study hard. [[EvilIsCool It makes you evil]].
59** Alternatively:
60-->Knowledge is power.\
61Power corrupts.\
62Corruption is a crime.\
63Crime never pays.\
64Study hard. It makes you broke.
65* There is one joke regarding space...[[ThePowerOfCheese and cheese.]]
66-->Swiss cheese has holes.\
67Each hole takes the space where cheese would be.\
68The more cheese you get, the more holes it will have.\
69As it has more holes, you get less cheese.\
70The more cheese you have, the less cheese you get.
71[[/folder]]

73[[folder:Literature]]
74* In ''Literature/{{Discworld}}'', libraries warp spacetime because "knowledge=power=energy=matter=mass", and enough mass gives you a blackhole.
75* The ''Literature/TheSecretsOfDroon'', the Wand of Urik works by [[RealityWarper making illogical syllogisms true]]. For example, "Cape is blue/Water is blue/Cape is water" turns a blue cape into a pool of water. Or "Stone is good/Fountain is good/Stone is fountain" turns a demon of stone into an ornate fountain.

78[[folder:Live-Action TV]]
79* From ''Series/TheColbertReport'':
80-->''"I live by syllogisms: God is love. Love is blind. Music/StevieWonder is blind. Therefore, Stevie Wonder is God. I don't know what I'd believe in if it wasn't for that."''
81* The ''Series/GilmoreGirls'' episode "The Third Lorelai" has the following exchange between Lorelai and her father.
82-->'''Richard''': I just got off the phone. Long distance.\
83'''Lorelai''': God?\
84'''Richard''': London.\
85'''Lorelai''': God lives in London?\
86'''Richard''': My mother lives in London.\
87'''Lorelai''': Your mother is God?
88* An episode of ''Series/YesMinister'' called this by name, as "The Politician's Syllogism", specifically the form: "Something must be done. This is something. Therefore we must do this." The two different meanings of "something": "A solution to this problem" and "A thing" are mixed and said to be the same.
89[[/folder]]
90
91[[folder:Theater]]
92* ''Theatre/AnyoneCanWhistle'' explains in "simple" terms what's wrong with leftists:
93-->The opposite of left is right,\
94The opposite of right is wrong,\
95So anyone who's Left is wrong -- right?
96* [[JustForFun/TheZerothLawOfTropeExamples Shakespeare did it first.]] In ''Theatre/AsYouLikeIt'', Touchstone proves that Corin is going to hell because he's never been in court.
97-->'''Touchstone:''' Why, if thou never wast at court, thou never sawest good manners; if thou never sawest good manners, then thy manners must be wicked; and wickedness is sin, and sin is damnation. Thou art in a parlous state, shepherd.
98* In ''Theatre/TwelfthNight'', Feste attempts this to make excuse for his lateness:
99-->'''Olivia''': Take the fool away.\
100'''Feste''': Do you not hear, fellows? Take away the lady.\
101Olivia: Go to, you're a dry fool; I'll no more of you: besides, you grow dishonest.\
102'''Feste''': Two faults, madonna, that drink and good counsel will amend: for give the dry fool drink, then is the fool no longer dry; bid the dishonest man mend himself: if he mend, then he is no longer dishonest: if he cannot, let the botcher mend him: anything that's mended is but patched: virtue that transgresses is but patched with sin; and sin that amends is but patched with virtue: if that this simple syllogism will serve, so; if it will not, what remedy? As there is no true cuckold but calamity, so beauty's a flower. — The lady bade take away the fool; therefore, I say again, take her away.
103* In ''Theatre/{{Hamlet}}'', the gravedigger and Hamlet make wordplay on "lying" (physically remaining in one place and fibbing):
104-->'''Hamlet''': Whose grave's this, sirrah?\
105'''Clown''': Mine, sir. [sings]\
106'''Hamlet''': I think it be thine indeed, for thou liest in't.\
107'''Clown''': You lie out on't sir, and therefore 'tis not yours. For my part, I do not lie in't, yet it is mine.\
108'''Hamlet''': Thou dost lie in't, to be in't and say it is thine. 'Tis for the dead, not for the quick; therefore thou liest.\
109'''Clown''': 'Tis a quick lie, sir; 'twill away again from me to you.\
110'''Hamlet''': What man dost thou dig it for?\
111'''Clown''': For no man, sir.\
112'''Hamlet''': What woman, then?\
113'''Clown''': For none, neither.\
114'''Hamlet''': Who is to be buried in't?\
115'''Clown''': One that was a woman, sir; but, rest her soul, she's dead.\
116'''Hamlet''' [to Horatio]: How absolute the knave is! We must speak by the card, [[LampshadeHanging or equivocation will undo us.]]
117* Shakespeare really loved this trope. In ''Theatre/MuchAdoAboutNothing'', Beatrice asks Benedick what happened when he challenged Claudio to a duel to defend Hero.
118-->'''Benedick''': Only foul words, and thereupon I will kiss thee.\
119'''Beatrice''': Foul words is but foul wind, and foul wind is but foul breath, and foul breath is noisome. Therefore I will depart unkissed.
120* ''Music/LesLuthiers'' has one example with one of the songs composed by the titular character of the "Manuel Darío" piece. He claims it's philosophical, and that [[TheDitz he doesn't get the meaning behind it]].
121-->''I love you more than my life''\
122''My life is you''\
123''But if my life is you''\
124''And I love you more than my life''\
125''Then that means''\
126''That I love you more than yourself!''
127[[/folder]]
128
129[[folder:Web Comics]]
130* In [[http://www.giantitp.com/comics/oots0725.html this]] ''[[Webcomic/TheOrderOfTheStick Order of the Stick]]'', the Empress is committing the Four Terms fallacy by using "grown larger" in two different senses: Dragons that are more powerful have grown larger (as a result of age), so she thinks that if she grows larger (by eating more and getting fat) that she will also be more powerful. That's not the only fallacy involved in her reasoning, either; she's also committing FalseCause, by attributing power to size.
131[[/folder]]
132
133[[folder:Web Original]]
134* On Website/TVTropes, the trope names NothingIsScarier and NothingIsFunnier are a {{pun}} based on the fallacy. The actual tropes are about how "nothing" (leaving it to the audience's imagination) can in many cases be more effective than actually showing what's so scary or funny, but the joke behind the titles is that phrasing it like this can be read as implying it to be the ''inherently best'' option.
135[[/folder]]
136
137[[folder:Western Animation]]
138* In the ''WesternAnimation/FamilyGuy'' episode [[Recap/FamilyGuyS9E8NewKidneyInTown "New Kidney in Town"]], [[ItMakesSenseInContext Peter attempts to make his own Red Bull]]. When Brian objects to using kerosene as an ingredient, Peter explains it thusly:
139-->''Kerosene is fuel, Brian. Red Bull is fuel. Kerosene is Red Bull.''
140* Played for laughs in a ''WesternAnimation/{{Histeria}}'' sketch about René Descartes (and several other jokes on the same topic): After Descartes makes his famous proposition that "I think, therefore I am,"[[labelnote:Meaning]]If he can think at all, he must exist.[[/labelnote]] a cavalcade of distractions cause him to proclaim "I can't think!",[[labelnote:meaning]]He is not literally unable to think, he just can't think ''clearly''.[[/labelnote]] whereupon he disappears in a PuffOfLogic.
141[[/folder]]
142
143[[folder:Real Life]]
144* The most famous version is probably this:
145-->''All the world loves a lover\
146I love you, therefore I am a lover\
147You are all the world to me, therefore you love me''
148* Commonly used in LSAT testing for law school admissions in the United States. For example, using the word interest to mean financial stake, concern, or welfare. "The judge has no financial ties to the settlement with ABC Company. He is completely disinterested." This is not the same thing as saying he is "uninterested."
149* Mathematics easily falls prey to this if you ignore a few key rules, e.g.:
150-->x/x=1\
1510/x=0\
152x/0 is undefined\
1530/0 is simultaneously 1,0, and undefined\
1541 is equal to 0 and both are undefined.
155* Also in mathematics:
156-->Women = Time, Money\
157Since Time = Money,\
158Women = Money, Money\
159= Money squared\
160Since Money = the root of all Evil,\
161Women = (the square root of Evil) squared\
162[[HeManWomanHater Women = Evil]]
163* Again in mathematics:
164-->Power = Work / Time\
165Since Knowledge = Power and Time = Money,\
166It follows that Knowledge = Work / Money\
167Solving for Money, we get:\
168Money = Work / Knowledge\
169As Knowledge approaches zero, Money approaches infinity, regardless of the value of Work.\
170Therefore: The less you know, the more you make.
171* In 1952, Noah S. "Soggy" Sweat, Jr., a Mississippi lawmaker, made the [[https://en.wikipedia.org/wiki/If-by-whiskey "If-by-whiskey" speech]], equivocating on whiskey, being simultaneously opposed to it as the drink which destroys homes, but also being in favor of it as the drink which brings cheer to men and brings revenue to help the orphans, the poor, the infirm, the crippled, the blind, and the elderly:
172-->If when you say whiskey you mean the devil's brew, the poison scourge, the bloody monster, that defiles innocence, dethrones reason, destroys the home, creates misery and poverty, yea, literally takes the bread from the mouths of little children; if you mean the evil drink that topples the Christian man and woman from the pinnacle of righteous, gracious living into the bottomless pit of degradation, and despair, and shame and helplessness, and hopelessness, then certainly I am against it. But, if when you say whiskey you mean the oil of conversation, the philosophic wine, the ale that is consumed when good fellows get together, that puts a song in their hearts and laughter on their lips, and the warm glow of contentment in their eyes; if you mean Christmas cheer; if you mean the stimulating drink that puts the spring in the old gentleman's step on a frosty, crispy morning; if you mean the drink which enables a man to magnify his joy, and his happiness, and to forget, if only for a little while, life's great tragedies, and heartaches, and sorrows; if you mean that drink, the sale of which pours into our treasuries untold millions of dollars, which are used to provide tender care for our little crippled children, our blind, our deaf, our dumb, our pitiful aged and infirm; to build highways and hospitals and schools, then certainly I am for it. This is my stand. I will not retreat from it. I will not compromise.
173* Then there's the story about the parent who buys {{Hentai}} for their 10-year-old, only to return it in a rage to the store where they bought it, because despite the explicit picture on the front, and the ratings and warnings all over the box, they reasoned that, [[AnimationAgeGhetto "It's animated, cartoons are animated]], and [[WhatDoYouMeanItsNotForKids cartoons are for kids, so it must be for kids!"]]
174* A less humorous one is parents or other authority figures mixing the meanings of "respect" in the form of "If you don't respect me [obey my authority] I won't respect you [treat you like a real person]."
175* On October 19, 2015, the tech entrepreneur Paul Graham [[https://twitter.com/paulg/status/656268067316613124 tweeted]]: "When you accuse Silicon Valley of x, you're implicitly saying x works well, which doesn't seem smart if you're against x."
