In this thought-provoking conversation, Dan Barker, a former evangelical preacher turned prominent atheist and co-president of the Freedom from Religion Foundation, explains the current state of separation of Church and State, the influence of Catholicism on the Supreme Court, and the ongoing debates surrounding public education and religious symbols.

Barker also discusses the legal challenges tackled by his organization, and introduces “Contraduction,” a new philosophical concept that reexamines how beliefs and arguments can reverse in order and meaning.

Plus, the moral implications of belief systems and the fine-tuning argument for the existence of God, the nature of nothingness, and free will.

Dan Barker is co-president of the Freedom From Religion Foundation, co-host of Freethought Radio, and co-founder of The Clergy Project. He worked 19 years as an evangelical minister and is a member of the Lenape (Delaware) tribe of American Indians. His new book is Contraduction.
