SUMMA THEOLOGICA LAW said before. For it belongs to reason to order us to our end, which is the primary source regarding our prospective action, as the Philosopher says. And the ST I–II source in any kind of thing is the measure and rule of that kind of thing (e.g., units in numbers and first QUESTION 90 movements in movements). And so we conclude that law belongs to reason. On the Essence of Law Reply Obj. 1. We say that law, since it is a rule or measure, belongs to something in two ways. It belongs FIRST ARTICLE in one way as to what measures and rules. And law Does Law Belong to Reason? in this way belongs only to reason, since measuring We thus proceed to the first inquiry. It seems that law and ruling belong to reason. Law belongs to some- does not belong to reason, for the following reasons: thing in a second way as to what is ruled and mea- Objection 1.

Reason has from the will the power source of human acts, as is evident from what I have to induce activity, as I have said before, since reason 463 464 AQUINAS commands means because one wills ends.

For he says in the Ethics of reason needs to rule the will regarding the means that “we call those laws just that constitute and pre- commanded in order that the willing have the nature serve happiness and its particulars by citizens’ sharing of law.

For example, fire, Common Good? which is hottest, causes heat in composite material substances, which we call hot insofar as they share We thus proceed to the second inquiry. It seems that in fire. And so, since we speak of law in the first place law is not ordained for the common good as its end, because of its ordination to the common good, every for the following reasons: other precept regarding particular acts has the nature Objection 1.

Therefore, law is ordained both for the as we call the common good the final cause, not by common good and for the private good of individuals. sharing in a genus or species. On the contrary, Isidore says in his Etymologies Reply Obj. 3.

And what measure. And as reason is the source of human acts, reason so establishes has the nature of law. so also is there in reason itself something that is the source of all other kinds of acts. And so law needs chiefly and especially to belong to this source.

Therefore, any head of a household can make laws regarding his household. We thus proceed to the fourth inquiry. It seems that On the contrary, Isidore says in his Etymologies, promulgation is not an essential component of law, and the Decretum maintains: “Laws are ordinances for the following reasons: of the people whereby elders and commoners together Objection 1.

But as regards the creatures who hear or read God’s law, QUESTION 91 the promulgation cannot be eternal. Reply Obj. 3. Law signifies actively ordaining things for an end, namely, that law ordain things for On Different Kinds of Law an end. And law does not signify being ordained for an end, that is, that law itself be ordained for another FIRST ARTICLE end, except incidentally in the case of human rulers, Is There an Eternal Law? whose end is extrinsic to themselves. And then the We thus proceed to the first inquiry. It seems that rulers’ laws also need to be ordained for that extrinsic there is no eternal law, for the following reasons: end. But the end of God’s governance is God himself, Objection 1. Every law is imposed on particular and his law is indistinguishable from himself. And so persons.

And so it is Choice posits two kinds of law, one kind eternal, and clear that the natural law is simply rational creatures’ the other temporal, which he calls human. participation in the eternal law. I answer that law is a dictate of practical reason, Reply Obj. 1. The argument of this objection as I have said before. But there are similar processes would be valid if the natural law were to be something of practical and theoretical reason, since both proceed different from the eternal law.

And so things that relate to we consider such acts in their own species. Therefore, such inclinations belong to the natural law (e.g., that if we are speaking about virtuous acts as virtuous, human beings shun ignorance, that they not offend then all virtuous acts belong to the natural law.
