 Street’s argument has also been challenged by such critics as Russ Shafer-Landau (2012). However, her argument, and similar arguments, have been acknowledged by some moral realists, such as David Enoch (2011) and Erik Wielenberg (2014) to pose a significant problem for their view. Enoch, for example, even though he offers a response to Street’s argument, evidently has some worries about the strength of his reply. Wielenberg, to avoid the criticism that in a non-theistic universe it would be extremely lucky if evolution selected for belief in objectively true moral values, proposes that the natural laws that produce this result may be metaphysically necessary, and thus there is no element of luck. However, many philosophers will see this view of natural laws as paying a heavy price to avoid theism. It might appear that Street is arguing straightforwardly that evolutionary theory makes it improbable that humans would have objective moral knowledge. However, it is not evolution by itself that predicts the improbability of objective moral knowledge, but the conjunction of evolution and metaphysical naturalism. A good deal of the force of Street’s argument stems from the assumption that naturalism is true, and therefore that the evolutionary process is one that is unguided. Since it is not evolution by itself that poses a challenge to moral realism but the conjunction of evolution and metaphysical naturalism, then rejecting naturalism provides one way for the moral realist to solve the problem. It does appear that in a naturalistic universe we would expect a process of Darwinian evolution to select for a propensity for moral judgments that track survival and not objective moral truths. Mark Linville (2009, 391–446) has developed a detailed argument for the claim that it is difficult for metaphysical naturalists to develop a plausible evolutionary story as to how our moral judgments could have epistemological warrant. However, if we suppose that the evolutionary process has been guided by God, who has as one of his goals the creation of morally significant human creatures capable of enjoying a relation with God, then it would not seem at all accidental or even unlikely that God would ensure that humans have value beliefs that are largely correct.
