继承了柏拉图哲学和斯多葛派哲学,西塞罗自然法思想同样具有神学主义特质。以泛神论的方式,西塞罗将自然看做永恒的理性和永恒的神灵。西塞罗认为,自然法的本质是神的永恒的理性,神与人共享同样的理性,只有合乎神的理性的法律才是正义的法律。正视西塞罗自然法思想的神学主义特质,有助于理解神学的与非神学的自然法思想的分歧,进而深入思考自然法的本质。 Inheriting Plato’s philosophy and Stoicism, Cicero’s Natural Law also possesses theological qualities. In a pantheistic way, Cicero will naturally be seen as eternal rational and eternal god. Cicero held that the essence of natural law is God’s eternal rationality, that God shares the same rationality with human beings, and that only law in accordance with divine reason is the law of justice. Facing the theological characteristics of Cicero’s idea of ​​natural law helps to understand the differences between the theological and non-theological ideas of natural law and further ponders over the nature of natural law.
