Humanism
Philosophy that relies entirely on reason without religion, based originally on Greek philosophy. Humanism rejects the idea that there is a supernatural being responsible for the creation of the universe. Humanists rely instead on a superior understanding that man is responsible for his actions and that purpose in the universe is far more complicated than a faith in a God. The IHEU has a minimum Statement on Humanism:
Humanism is a democratic and ethical life stance, which affirms that human beings have the right and responsibility to give meaning and shape to their own lives. It stands for the building of a more humane society through an ethic based on human and other natural values in the spirit of reason and free inquiry through human capabilities. It is not theistic, and it does not accept supernatural views of reality."
