Humanism is a rational philosophy informed by science, inspired by art, and motivated by compassion.
Humanism is a framework of finding meaning and purpose grounded in this world without reference to supernatural powers and divinities. While Humanism may often be understood as “code” for not believing in God, its tenants underscore multiple commitments to what they do believe, including the use of reason, the importance of social relationships, and an ethic of care for humanity and the natural world. What makes Humanism a religious tradition is how it functions as a system of meaning-making and ethical guidance. Historically, Humanism has roots that extend into antiquity. Contemporary groups such as the American Humanist Association (AHA) trace their origins to the 1933.
