 Aquinas is regrettably inexplicit about how the first practical principles yield moral principles, precepts or rules that have the combined generality and specificity of the precepts found in the portion of the biblical Decalogue (Exod. 20.1–17; Deut. 5.6–21) traditionally called moral (the last seven precepts, e.g. parents should be reverenced, murder is wrong, adultery is wrong, etc.). But a reconstruction of his scattered statements makes it clear enough that in his view a first implication of the array of first principles, each directing us to goods actualisable as much in others as in oneself, is this: that one should love one’s neighbor as oneself.
