"As a magician, I promise never to reveal the secret of any illusion to a non-magician, unless that one swears to uphold the Oath in turn. I promise never to perform any illusion for any non-magician without first practicing the effect until I can perform it well enough to maintain the illusion of magic."

The two of the largest American magicians organizations, [https://www.magician.org/ The International Brotherhood of Magicians] (founded 1922, based in St. Charles, Missouri) and The Society of American Magicians (founded in 1902), in 1993 issued a joint ethics statement that essentially codified the magician's oath into their organizations. If someone wants to be a member of these organizations, they have to adhere to this code of ethics. In addition to maintaining secrecy, the ethics statement also addresses intellectual property rights, false statements, commercial rights and the humane treatment of animals.
