Progressive Atheism: How Moral Evolution Changes the God Debate

This monograph advances a distinctive argument that links atheism to moral and conceptual progress across human history. Schellenberg contends that humanity's evolving moral sensibilities and expanding conceptual frameworks provide compelling grounds for rejecting traditional theistic belief, while simultaneously opening new possibilities for understanding the divine that transcend conventional religious categories.

The work develops what Schellenberg terms "progressive atheism," which differs from standard atheistic positions by emphasizing temporal and developmental dimensions of the God debate. Rather than treating arguments for and against God's existence as timeless logical exercises, Schellenberg situates them within humanity's ongoing moral and intellectual maturation. He argues that many traditional conceptions of God reflect the moral limitations of earlier historical periods and become increasingly untenable as human ethical understanding deepens.

Central to Schellenberg's analysis is the claim that moral progress generates new evidential considerations against classical theism. He examines how evolving views on gender equality, animal welfare, and universal human dignity create tensions with scriptural depictions of divine commands and actions. The work suggests that a morally perfect being, as God is traditionally conceived, would not have sanctioned or commanded actions that contemporary moral consciousness recognizes as deeply problematic.

The monograph engages extensively with responses from theistic philosophers who argue that divine morality transcends human ethical evolution. Schellenberg counters by developing a sophisticated account of how genuine moral progress differs from mere cultural change, drawing on metaethical theories about moral knowledge and objective ethical truths. He maintains that recognizing moral progress does not require abandoning moral realism.

Significantly, Schellenberg's progressive atheism remains open to future religious possibilities. He argues that while current evidence and moral understanding support atheism regarding traditional conceptions of God, humanity's continued development might eventually enable recognition of transcendent realities currently beyond human comprehension. This distinguishes his position from dogmatic atheism that categorically denies any possible divine reality.

The work contributes to contemporary philosophy of religion by introducing a temporal, developmental framework typically absent from debates focused on abstract arguments. By connecting atheism to broader themes of human progress and moral evolution, Schellenberg offers a novel perspective that challenges both static theistic worldviews and purely negative atheistic stances. His approach suggests that the God debate itself must evolve alongside human moral and conceptual capacities.
