Western Culture and the Rule of Three
Trios, triplets, and triads abound in Western culture in many disciplines. Just a small sampling of memorable cultural triads include:
- Father, Son, and Holy Spirit
- Heaven, hell, and purgatory (Catholicism, primarily)
- Three Wise Men with their gold, frankincense, and myrrh
- Movies & Books
- The Good, the Bad, and the Ugly
- Sex, Lies, and Videotape
- Superman’s “Truth, Justice, and the American Way“
- Nursery rhymes such as the Three Little Pigs or Goldilocks and the Three Bears
- In a more general sense, there is the allure of trilogies as with Indiana Jones, The Godfather, The Matrix, Star Wars, and many others.
- U.S. Branches of Government: Executive, Judicial, and Legislative
- U.S. Declaration of Independence: “Life, liberty, and the pursuit of happiness”
- French motto: Liberté, Égalité, Fraternité

- Fire safety motto: Stop, Drop, and Roll
- Olympic motto: Citius, Altius, Fortius or Faster, Higher, Stronger
- Real estate: Location, Location, Location
Historic Rule of Three Speech Examples
Speechwriting is, of course, part of our culture. Examples of the Rule of Three can be found in some of the most famous speeches ever delivered:
- Julius Caesar
- “Veni, vidi, vici” (I came, I saw, I conquered)
- Shakespeare’s Julius Caesar
- “Friends, Romans, Countrymen. Lend me your ears.“
- Abraham Lincoln’s Gettysburg Address
- “We can not dedicate — we can not consecrate — we can not hallow — this ground.“
- “Government of the people, by the people, for the people“
- General MacArthur, West Point Address, 1962
- “Duty, Honor, Country” [repeated several times in the speech]
- Barack Obama, Inaugural Speech
- “we must pick ourselves up, dust ourselves off, and begin again the work of remaking America“
What’s Magical About the Rule of Three?
It is reasonable to ask what’s so special about three? Why is it so popular in our culture? Aren’t there just as many examples of two- or four-element famous speech lines?
For a famous duo, there is Patrick Henry’s “Give me liberty or give me death.”
For a classic quartet, it is tough to beat Winston Churchill’s “I would say to the House as I said to those who have joined this government: I have nothing to offer but blood, toil, tears and sweat.”
Despite examples like these, there is something magical about the Rule of Three in the way that it allows a speaker to express a concept, emphasize it, and make it memorable.
In his book Writing Tools: 50 Essential Strategies for Every Writer, Roy Peter Clark provides insights to the magic of the number three:
… the “encompassing” magic of number three … in our language or culture, three provides a sense of the whole …
… in the anti-math of writing, the number three is greater than four. The mojo of three offers a greater sense of completeness than four or more. …
Use one for power. Use two for comparison, contrast. Use three for completeness, wholeness, roundness. Use four or more to list, inventory, compile, and expand.
Rhetorical Devices — Rule of Three
The rule of three describes triads of all types — any collection of three related elements. Two more specific triad variants are hendiatris and tricolon.
A hendiatris is a figure of speech where three successive words are used to express a central idea.
Examples of hendiatris include:
- “Veni, vidi, vici.” [Julius Caesar]
- “Liberté, Égalité, Fraternité“ [French motto]
- “Citius, Altius, Fortius” [Olympic motto]
- “Wine, women, and song” [Anonymous]
A tricolon is a series of three parallel elements (words or phrases). In a strict tricolon, the elements have the same length but this condition is often put aside.
Examples of tricola include:
- “Veni, vidi, vici.” [Julius Caesar]
- “Be sincere, be brief, be seated.” [Advice for speakers from Franklin D. Roosevelt]
- “Tonight, we gather to affirm the greatness of our nation – not because of  the height of our skyscrapers, or  the power of our military, or  the size of our economy.” [Barack Obama, Keynote speech to Democratic National Convention, July 2004]
