 The precepts of the natural law are binding by nature: no beings could share our human nature yet fail to be bound by the precepts of the natural law. This is so because these precepts direct us toward the good as such and various particular goods (ST IaIIae 94, 2). The good and goods provide reasons for us rational beings to act, to pursue the good and these particular goods. As good is what is perfective of us given the natures that we have (ST Ia 5, 1), the good and these various goods have their status as such naturally. It is sufficient for certain things to be good that we have the natures that we have; it is in virtue of our common human nature that the good for us is what it is.
