The natural processes that govern the operation of the cosmos are not moral sources. They are simply the givens of physics and mathematics, elemental facts of natural reality lacking inherent meaning or purpose or normativity. Positive and negative electrical charges do not attract one another because that is right or just, they do so simply because that is simply how they work. The evolutionary development of substance and life forms is not a moral source. These also just happen as they happen. What then in naturalism’s cosmos could serve for humans as a genuine moral guide or standard, having a source apart from human desires, decisions, and preferences and thus capable of judging and transforming the latter. I cannot think of any. – Christian Smith (from, Atheist Overreach: What Atheism Can’t Deliver)
