Atheism is the absence of belief in any god or gods. It is not itself a religion, and atheists do not share a single worldview beyond that one point. This guide sets out the basics and the common misunderstandings.
Atheism, agnosticism and religion
- Atheism – does not believe a god exists. “Strong” atheism claims no god exists; “weak” atheism simply lacks belief.
- Agnosticism – holds that the existence of God is unknown or unknowable. A person can be an agnostic atheist (doesn’t know, doesn’t believe).
- Religion – an organized system of belief in and worship of the divine.
What atheists tend to believe
Because atheism only answers one question, atheists vary widely. Many are secular humanists, holding that morality and meaning come from human reason, empathy and shared experience rather than divine command. Others simply have no strong philosophy attached to their non-belief.
Common misconceptions
- “Atheists have no morals” – atheists generally ground ethics in human wellbeing and reciprocity.
- “Atheism is a religion” – it has no doctrine, scripture, clergy or rituals.
- “Atheists are certain there is no God” – many are agnostic atheists who simply see no evidence.
Public figures who are atheist or non-religious
Examples include UK Prime Minister Keir Starmer, who has said “I don’t believe in God,” and, for much of his life, media mogul Ted Turner.
FAQ
Is atheism a religion?
No. It is the lack of belief in gods, with no shared doctrine or institution.
What is the difference between atheist and agnostic?
Atheism is about belief (not believing in God); agnosticism is about knowledge (not knowing whether God exists). The two often overlap.
Do atheists believe in an afterlife?
Most do not, since belief in an afterlife usually depends on religious teaching.
