 Thus, if, with Sharon Street (2006), one holds that in many cases “it is more scientifically plausible to explain human evaluative attitudes as having evolved because they help us to survive and to have surviving offspring, than because they are true” (de Lazari-Radek &amp; Singer 2014: 180), one can debunk many of the beliefs competing with the Axiom of Universal Benevolence, such as those purportedly justifying partial or personal reasons for action. If Benevolence is not debunked, and if it can in fact be accounted for straightforwardly as a result of reason coming as a unity or package, such that either “we have a capacity to reason that includes the capacity to do advanced physics and mathematics and to grasp objective moral truths, or we have a much more limited capacity to reason that lacks not only these abilities, but others that confer an overriding evolutionary advantage. If reason is a unity of this kind, having the package would have been more conducive to survival and reproductions than not having it.” (de Lazari-Radek and Singer: 183).
