Freemasonry, often called the “Craft” by its members, is founded on metaphors of architecture. Following the practice of the ancient stonemason guilds, Freemasons use special handshakes, words, and symbols to not only to identify each other, but to help, as William Preston said in 1772, “imprint upon the memory wise and serious truths.”
Although every new Freemason takes an oath – and vows to keep secret the metaphors of Masonry – the metaphors are only used to help Masons become better men; and there’s certainly no secret surrounding what it takes to be good and true.
