Religion

=== Agnosticism and atheism ===
{{Main|Atheism|Agnosticism|Irreligion|Humanism}}
The terms [[atheist]] (lack of belief in gods) and agnostic (belief in the unknowability of the existence of gods), though specifically contrary to theistic (e.g., Christian, Jewish, and Muslim) religious teachings, do not by definition mean the opposite of religious. The true opposite of religious is the word irreligious. [[Irreligion]] describes an absence of any religion; [[antireligion]] describes an active opposition or aversion toward religions in general. There are religions (including Buddhism and Taoism) that classify some of their followers as agnostic, atheistic, or [[nontheism|nontheistic]]. For example, in ancient India, there were large atheistic movements and traditions ([[Hindu atheism|Nirīśvaravāda]]) that rejected the [[Vedas]], such as the atheistic [[Ājīvika]] and the [[Ajñana]] which taught agnosticism.
