Believers may unwittingly assume a special burden of proof is on them, while assuming the atheist has none. The problem here is that every person—atheist, skeptic, or agnostic included—has a worldview with various assumptions about the nature of reality, ethics, knowledge, and life’s meaning. Everyone takes a stance in both theory and practice. How often we meet critics who borrow heavily from a biblical worldview about human dignity and rights, moral responsibility, right and wrong, purpose and meaning in order to sustain their own worldview rooted in purposeless, mindless, valueless, impersonal, material origins! All worldviews make truth claims; therefore, all—not just the Christian faith—stand in need of justification. We can wrongly assume that only the believer has a burden of proof and that the unbeliever does not—that somehow his views escape intellectual scrutiny. — Paul Copan (from, Learn How (Not) To Doubt)
