Can Darwinism Support Morality?

In this powerful and intellectually provocative episode, Dr. Douglas Groothuis reads his essay from the Summer 2025 issue of Salvo Magazine, titled “Escape from the Acid Bath: Can Darwinism Support Morality?” Drawing from his broader work in Christian Apologetics (2nd ed.), Dr. Groothuis critically examines the claim that Darwinian evolution can serve as a sufficient foundation for objective morality, contrasting that with the moral implications of a theistic worldview grounded in divine character and design.

This essay-style episode surveys the views of prominent atheists such as Daniel Dennett, Karl Marx, Richard Dawkins, and Sam Harris, and demonstrates the internal philosophical weaknesses of moral theories rooted in evolutionary naturalism. Instead, Dr. Groothuis makes a compelling case for Judeo-Christian theism as the only viable foundation for universal moral truths.

🔑 Main Takeaways

• Daniel Dennett’s “universal acid” metaphor reveals how Darwinism corrodes all foundations of purpose and morality in the universe.

• Evolutionary theories of morality — while attempting to explain altruism, cooperation, and conscience — fail to justify why these traits are morally binding or intrinsically good.

• C.S. Lewis’s insights in The Abolition of Man clarify why objective moral values cannot arise from mere instincts or natural processes.

• Even atheists who believe in objective morality (atheistic moral realists) must borrow metaphysical tools from theism to make their arguments coherent.

• The essay concludes that Darwinism, as a materialist worldview, lacks the resources to support moral law — but the Christian tradition offers a firm foundation for it.
