Types

Humanism

While atheism is merely the absence of belief, humanism is a positive attitude to the world, centred on human experience, thought, and hopes.

Secularism

Secularists oppose religion or the religious being afforded privileges, which - put another way - is the same as disadvantaging others.

Rationalism

Rationalism is an approach to life based on reason and evidence and rejects authority that cannot be proved by experience.

Atheist Buddhism

The Buddha did not claim to be in any way divine, nor does Buddhism involve the idea of a personal god.

Humanistic Judaism

Humanistic Judaism doesn't proclaim that there is no God, but it does do without God.

Christian Atheism

Christian Atheists, or non-realistic Christians, want to remove what they see as the fairy tale elements of Christianity.

Postmodernism

For postmodernists every society is in a state of constant change; there are no absolute values, only relative ones; nor are there any absolute truths.

Unitarian Universalism

Unitarian Universalism is not an atheist movement, but proclaims the importance of individual freedom of belief and so it is a movement into which some atheists may comfortably fit.
