A Methodical System of Universal Law. Johann Gottlieb Heineccius

qualities and relations of things are the ultimate standard. The former may vary, but the latter are unchangeable. The ultimate measure of opinions, which is truth or nature, is constant, immutable.

CHAPTER III

       Of the rule of human actions, and the true principle of the law of nature.

      SECTION LX

      Of what nature or kind the rule of human action must be.

      Such, we have already seen, is the nature of our free actions, that they must have a rule to direct them (§4); there we likewise shewed that a rule could not serve the purposes of a rule, if it be not streight or right, certain, evident, and invariable, and have external as well as internal obligation. Let us now enquire a little more accurately what this rule is which hath all these properties essential to a rule for human, free, moral actions.^*<41>

      SECTION LXI

      The rule of human actions is not to be found in us, but without us.

      The rule of human actions must either be within us or without us. If it be within us, it can be none other but either our own will, or our understanding and conscience. But neither of these faculties is always right, neither of them is always certain, neither of them is always the same and invariable; wherefore neither any of them, nor both of them together, can be the rule of human actions; whence it follows that the rule of human actions is not to be found in ourselves; but if there be any such, it must be without us.

      SECTION LXII

      It is to be found in the will of God.

      Now without us exist other created beings, and likewise a God, the author of all things which exist. But since we are enquiring after a rule of human actions, carrying with it an external obligation (§9) and made known or promulgated to all mankind by right reason (§11); and since external obligation consists in the will of some being, whose authority we acknowledge (§9), there being no other whose authority we are obliged more strictly to acknowledge than the infinitely perfect and blessed God (§10); and seeing he alone can promulgate any thing to us by right reason, of which he is the author, it follows, by necessary consequence, that the will of God must be the rule of human actions, and the principle or source of all natural obligation, and of all virtue.^*<42>

      SECTION LXIII

      The will of God is a right, certain, and constant rule.

      That this rule is right cannot be doubted, since an infinitely perfect Being cannot will what is not perfectly good and right: it must be a certain rule, since reason discovers it to all men; and it must be unvariable, because the will of God can no more change, or be changed, than God himself, or right reason, by which it is discoverable. Finally, it must be obligatory, since God hath the justest claim and title to our obedience; and men have no reason or right to decline his authority, and cannot indeed if they would. Hence at the same time it is evident, that every will of God is not the rule of human actions, but his obligatory will only.^*

      SECTION LXIV

      This rule may be called a law with regard to mankind.

      Since therefore the obligatory will of God, which we have shewn to be the only rule of human actions, is his will with respect to the actions of his rational creatures, as to acting or forbearing to act (§63); it is evident, that this rule, considered with relation to man, may properly be called a divine law, because it is the will of the supreme Being, commanding or forbidding certain actions with rewards and penalties (§9). But because there are other laws of <43> God to mankind which are made known by revelation, and are therefore called positive, those which are known to man by natural reason, are justly denominated natural; and according as they either command, prohibit, or permit, they are with good reason divided into affirmative, negative, or permissive.

      SECTION LXV

      The explication of the divine justice may be deduced from the divine will.

      Now since this divine will, or divine natural law, is the source and principle of all justice (§63), it follows that every action, not only human, but divine, which is conformable to this divine will, is just; and therefore it is objected, without any reason, against this doctrine, that there could not be any such thing as divine justice, were there no other principle or source of the law besides the divine will.^*<44>

      SECTION LXVI

      The difference between the rule of divine and the rule of human justice, in what does it consist?

      Herein chiefly lies the difference between divine and human justice, that with regard to the former there is no law or co-action; whereas the latter includes in it a respect to a law, and external obligation or co-action (§65 & §64). Wherefore the divine will, as it is a rule of action to men, carries with it a commination of some evil or punishment to transgressors; tho’ that punishment be not, as in human laws, defined and ascertained, but be, for the greater part, indefinite, and reserved to God himself, to be inflicted according to his wisdom and justice.^*<45>

      SECTION LXVII

      That we may apply this rule, there must be some principle or criterion by which it may be known or ascertained.

      But since it cannot be doubted that there is no other rule of human actions but the will or law of God (§63), it is to be enquired how we may come to the certain knowledge of this law. But since it is universally acknowledged to be promulgated to all men by right reason (§11), and since right reason is our faculty of reasoning, by which we deduce truths from other truths by a chain of consequences (§15), it is obvious that there must be some truth or proposition, from which what is agreeable to the will of God, and therefore just, may be ascertained by necessary consequence. There must then be some universal principle of science with regard to the law of nature.^*

      SECTION LXVIII

      This principle must be true, evident, and adequate.

      Every principle of science must be true, evident, and adequate; wherefore the principle of science, with respect to natural law, must be true; lest being false or fictitious, the conclusions inferred from it be such likewise: it must be evident, and that not only in this sense, that it is intelligible to the literate; but universally, to the unlearned as well as the learned, all being equally under obligation to <46> conform themselves to the law of nature. In fine, it must be adequate, or of such an extent, as to include in it all the duties of men and citizens, not Christians only, but those also who have not the benefit of divine revelation.^†

      SECTION LXIX

      Whence this principle is not to be found in the sanctity of God.

      Therefore we must not expect to find this principle of the law of nature in the conformity of our actions to the sanctity of God: for tho’ the proposition should be granted to be true, yet it is not evident enough, nor of such a nature, as that all the duties of men and citizens can be inferred and proved from it.^*

      SECTION LXX

      Nor in the justice and injustice of actions considered in themselves.

      Nor is this a sufficient principle, “that what is in its own nature just is to be done, and what is in its own nature unjust is not to be done.” For tho’ we have already admitted, that certain actions are <47> in their own nature good, and others evil, and that man is therefore obliged to perform the one, and to avoid the other, by an intrinsic obligation (§8); yet an action antecedently
