Humanist Manifesto is the title of three manifestos laying out a Humanist worldview. They are the original Humanist Manifesto (1933, often referred to as Humanist Manifesto I), the Humanist Manifesto II (1973), and Humanism and Its Aspirations (2003, a.k.a. Humanist Manifesto III). The Manifesto originally arose from religious Humanism, though secular Humanists also signed. In addition, there is a similar document entitled A Secular Humanist Declaration published in 1980 by the Council for Secular Humanism.
