Humanist Manifesto - Wikipedia
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.
The central theme of all three manifestos is the elaboration of a philosophy and value system which does not necessarily include belief in any personal deity or "higher power", although the three differ considerably in their tone, form, and ambition. Each has been signed at its launch by various prominent members of academia and others who are in general agreement with its principles.
In addition, there is a similar document entitled A Secular Humanist Declaration published in 1980 by the Council for Secular Humanism.
