Humanism and Its Aspirations subtitled 1., a successor to the Humanist Manifesto of 1933 is the most recent of the Humanist Manifestos published in 2003 by the American Humanist Association (AHA). The newest one is much shorter, listing six primary beliefs, which echo themes from its predecessors:
- Knowledge of the world is derived by observation, experimentation, and rational analysis. (See empiricism.)
- Humans are an integral part of nature, the result of unguided evolutionary change.
- Ethical values are derived from human need and interest as tested by experience. (See ethical naturalism.)
- Life’s fulfillment emerges from individual participation in the service of humane ideals.
- Humans are social by nature and find meaning in relationships.
- Working to benefit society maximises individual happiness.
