Internet Research: Rule of Three

By classical definition, great oratory is the felicitous product of style, substance and impact. That is, a masterful construction of words to create texts that are beautiful both to hear and read; a worthy theme that appeals, informs and inspires, and a memorable ability to open hearts, change minds, move nations.
- Lincoln's 1863 Gettysburg Address is still regarded by many as the most elegant, emotional, memorable blend of political content and style.
- Winston Churchill, “We Shall Fight on the Beaches”
- John F. Kennedy, “Inauguration Address”

The rule of three is a writing principle that suggests that things that come in threes are inherently funnier, more satisfying, or more effective than other numbers of things. The reader or audience of this form of text is also more likely to consume information if it is written in groups of threes. From slogans ("Go, fight, win!") to films, many things are structured in threes. Examples include The Three Stooges, Three Little Pigs, Three Billy Goats Gruff,Goldilocks and the Three Bears.
