3. Man is able to recognize God as the source of all good things, and in light of his knowledge of the good to direct his actions by the power of his will. He is also able either so to arrange his actions as to testify to his love and veneration for his creator and Lord, and so in an active way to serve his glory; or on the other hand in such a way, that in betraying neglect or hatred of him, he obscures that glory, so far as he is capable of doing so.
4. That an agent of this kind may be directed to the glory of God agreeably with his nature, he must be so placed that his happiness is connected with the preservation of due subordination to God, and his misery with the violation of that subordination. Consequently, he can only acquire or preserve that happiness to which he constantly aspires by the original law of his nature, avoiding the misery which he no less shuns by the same law, when he signifies by his actions the highest esteem for the Deity, the most intense love, and the most devoted veneration.5 And so far as he turns aside from this norm (i.e., by actions or omissions which betray contempt, neglect, or hatred of God), so far he may wander from the path of his own happiness, and veer toward the corresponding misery. Man easily understands, therefore, that this condition has been given him by God. And if happiness and misery are not always dispensed in this life on these terms, he can quite clearly infer from this very fact that some future state of the soul is to be expected.6
5. Moreover, there is strong confirmation that each man has more regard for his own happiness, the more he gives evidence in his individual actions of a soul devoted to God. For the great and good God, as he is the supreme dispenser of every kind of happiness or misery for men, so is he also the unique object of the most consummate beatitude which can come to man. Man cannot achieve beatitude either in the consciousness of his own finite perfections, or in the possession of things of less value than himself, or in the contemplation of abstract truths. He can enjoy it only in an immediate vision of God himself which will last forever, a vision of God reconciled with him, and preserving him with fatherly care; and this is necessarily accompanied by the most ardent love and unspeakable joy.7
6. The desire which God has given man for the most consummate happiness is strong evidence that such beatitude is available to him if he perseveres in due subordination to God. But if he defects from that straight path (and each man finds within himself innumerable symptoms of such defection) and loses the right to obtain this beatitude, offered by divine grace, one must not conclude that the glory of the divine perfection in the determination of man’s eternal state will be diminished. Rather grace should be illustrated still more clearly, whether in mercifully restoring that lost beatitude or in inflicting a punishment, whose severity and duration may attest how great was the beatitude lost, and how great the offense of lèse-majesté against God.
7. It is not easy to determine from nature how far in this degenerate condition of the human race, any ordering of our actions can contribute to obtaining that beatitude or avoiding an equal misery. But it is clear enough that if any way is left to man to secure the one and avoid the other (and on this matter the kindly dispensation of divine providence toward the human race bids one not simply to despair altogether), each man is able to hope with some prospect of justice that he will obtain it the more he gives evidence of devoted affection toward the Deity in his individual actions. And even the least likelihood of obtaining infinite good or escaping infinite evil ought to have more influence with us than all the considerations opposed to it.
8. We are also led to the same conclusion by the fact that the human mind is fitted to feel the greatest pleasure and delight in actions which are most comformable to reason. Such actions are, above all, those which show love, esteem, and veneration for a most perfect object. By contrast we feel the greatest repining and remorse in their opposites. Hence it is rightly said from of old: virtue is its own reward, vice its own punishment.8
9. All the considerations we adduce seem to conspire to suggest that the key to the significance of actions within a man’s power to bring happiness and avoid misery lies in the evidence they give in individual actions of the most intense love and reverence for the great and good God, and scrupulous avoidance of anything that suggests the contrary sentiment.
10. In every duty which has reference to God and in which his approval is expected, the intention of the divine will is of the first importance; and the will of God demands certain actions of men as a sign of love and veneration of himself and interprets contrary actions as indications of contempt or hatred, connecting the offering of the one or the absence of the other with the happiness of man, and the commission of the one or the neglect of the other with his misery; and therefore that will, declared by suitable signs, is called the divine law.9 And from what has been said it is clear that this law must be recognized as the highest norm of human actions. The actions which the law requires as a sign of love and devoted affection toward God are said to be prescribed by law. Actions, on the other hand, which the law requires us to interpret as indications of contempt, neglect, or hatred toward God are said to be forbidden by law. He who performs prescribed actions because they are prescribed (and as so performed they are called morally good), or omits forbidden actions, because they are forbidden, is said to obey the law; but he who commits forbidden actions (which are usually called morally bad), or omits prescribed actions, is said to transgress or violate the law. If an action prescribed by law is done, by someone either in ignorance that it is prescribed, or without regard to the prescription, that action is said to be not formally but materially good.
11. From this, we may determine those actions or omissions of men which are liable to the direction of law, and thus capable of moral good or evil. It is those actions and omissions which are done by men knowingly and voluntarily and not involuntarily or, which comes to the same thing, which are in the power of the agent to do or not to do, or depend on the determination of his will. Those sorts of actions and omissions, popularly called free, where there is a law laid down by which they are prescribed or forbidden, are imputable to man, for praise or for censure, reward or punishment; seeing that there may be in each and every one of them an appropriate or inappropriate sentiment toward God the author of the law.
12. Therefore no one can be held responsible for necessary things because they happen, or impossible things, because they do not. Only those things should be regarded as necessary which happen whether anyone wishes them to or not; not all these things are effectively determined by the mind willing them. Equally, those things alone should be said to be impossible which do not occur, whether anyone wishes them or not; not by any means all the things which the mind lacks the requisite disposition to will seriously.
13. But for any human action, or omission of it, to become a moral act, and thus imputable to man as good or evil according to what was said above, a law must exist which prescribes or forbids that action. This law is the will of God, as we described it in section 10, declared by suitable signs: that is, signs by which a man would be able to know the will of God and the duty which is incumbent on him in this respect according to the law, if he employed his reason rightly upon them and with due attention, as well as on the existence of the conditions which perhaps that law presupposes. That is, when these conditions are present, a man is not to be considered blameless if he is ignorant of the morality of his action, and, if he does that action, he is also to be regarded as consenting in some way to the morality involved in it.
14. We infer that where there is a law, the morality of every one of our free actions or omissions is to be judged on three heads: first, from the value of what is done or omitted, both considered in itself and clothed in all the circumstances which may urge that it be done or omitted here and now; second, from the manner and measure of knowledge which one may have about the action or its omission morally considered; i.e., about the law and the circumstances just mentioned; third, from the greater or lesser inclination of the will to what is done or aversion from what is omitted; including the motives by which the will is directed to the one or to the other.
15. As regards the first, it is certain that no circumstances of an action
