In the fictional Star Trek universe, the Rules of Acquisition are a collection of sacred business proverbs of the ultra-capitalist race known as the Ferengi.
In a later Deep Space Nine episode, "The Maquis: Part 1", Sakonna (a Vulcan) asks Quark (a Ferengi) to explain what a Rule of Acquisition is.
He states, "Every Ferengi business transaction is governed by 285 Rules of Acquisition to ensure a fair and honest deal for all parties concerned... well most of them anyway.
"[1] The first Rule was made by Gint, the first Grand Nagus of the Ferengi Alliance, a role with political, economic, and even quasi-religious duties.
[4] The Star Trek: Voyager episode "False Profits" mentions a book containing all of the Rules: Unabridged and fully annotated with all 47 commentaries, all 900 major and minor judgments, all 10,000 considered opinions.
