Below is American Atheists' Statement of Aims and Purposes . All applicants must read it before proceeding. Atheism may be defined as the mental attitude which unreservedly accepts the supremacy of reason and aims at establishing a life-style and ethical outlook verifiable by experience and scientific method, independent of all arbitrary assumptions of authority and creeds.
Materialism restores dignity and intellectual integrity to humanity.
It teaches that we must prize our life on earth and strive always to improve it. It holds that human beings are capable of creating a social system based on reason and justice. This is a commitment which is in its very essence life-asserting. It considers the struggle for progress as a moral obligation that is impossible without noble ideas that inspire us to bold, creative works. Materialism holds that our potential for good and more fulfilling cultural development is, for all practical purposes, unlimited.
