An atheist is someone who does not believe in the existence of God. An agnostic is someone who doubts the existence of God. The word *pagan *has several meanings. It can refer to someone who is a polytheist (i.e., believes in many gods); to someone who belongs to one of the neo-pagan earth-based religions (e.g., Wicca); to someone who has no religion (as opposed to an atheist who positively believes that there is no God); or to a hedonist (i.e., someone whose primary pursuit is personal pleasure).
