The phrase "scientia potentia est" (or "scientia est potentia or also "scientia potestas est") is a Latin aphorism meaning "knowledge is power". It is commonly attributed to Sir Francis Bacon, although there is no known occurrence of this precise phrase in Bacon's English or Latin writings. However, the expression "ipsa scientia potestas est" ('knowledge itself is power') occurs in Bacon's Meditationes Sacrae (1597). The exact phrase "scientia potentia est" was written for the first time in the 1668 version of the work Leviathan by Thomas Hobbes, who was secretary to Bacon as a young man.
