former case a stricter right is in question. Example: Titus is keeping $5.00 in order to pay a debt to Caius, who needs the money today; Balbus, who is very poor, asks Titus to give the money to him. Titus should pay Caius.
(c) Negative or prohibitory laws have precedence over affirmative or preceptive laws (see 371). Example: Titus is asked to write out a testimonial stating that he knows that Balbus is honest, competent, etc. Balbus has claims on the help of Titus on account of a promise made in the past; but Titus knows very well that Balbus is not competent, honest, etc. The law forbidding lies prevails here over the law that one keep a promise made.
292. Since rights and duties are correlative—there being a duty that corresponds to every right, and vice versa—and since both are regulated by law, the principles given for the apparent collision of laws can be applied to the apparent collision of rights.
(a) Rights of a higher kind have preference over rights of a lower kind. Therefore, the rights that arise from birth itself, or from the fact that one is a human being (e.g., the right to life), are superior to the rights that are acquired through some condition, such as inheritance or contract (e.g., the right to property, etc.). Example: Titus must get his child, who is in danger of death, to a hospital without delay. Balbus is getting ready for a pleasure ride, but Titus takes his car since there is no other ready means of getting to the hospital. Titus acts within his natural rights, if the car is returned safely and as soon as possible to the owner. According to civil law his act would be technical larceny, but in view of the necessity courts and juries would certainly not insist on the letter of the law.
(b) Inalienable rights (i.e., those which one may not renounce, because they are also duties), such as the right to serve God, the right to live, etc., are superior to alienable rights (i.e., those which one may renounce), such as the right to marry, the right to own property, etc. Example: One may surrender the right to drink intoxicants in order to serve God or preserve one's life.
293. The Basis of All Laws.—Prior to every other law and the ground and principle of all laws is the Eternal Law; for, since this is the plan of Divine Wisdom directing from eternity all acts and movements to their particular ends and to the end of the universe, it follows that all other laws are reflections of the eternal plan and realizations of the divine decree. The Eternal Law differs from other laws in various ways:
(a) as to duration. The Eternal Law existed before anything was made, whereas all other laws begin to exist when they are promulgated;
(b) as to breadth of application. The Eternal Law regulates, not only contingent things (such as actions) but also necessary things (such as that man should have a soul, hands and feet); for all things created, whether they be contingent or necessary, are subject to divine government. Human laws, as is evident, cannot regulate what is necessary (e.g., it would be foolish for them to decree that men must or must not have souls);
(c) as to subjects. The Eternal Law rules, not only rational creatures (i.e., angels and men), but also irrational creatures, such as matter, plants, and animals. The former are ruled through commands, which require that they direct themselves to their End; the latter are ruled through the inclinations given them by God, which move them to the ends He desires them to attain. Human laws cannot regulate the acts of irrational creatures, for these creatures cannot understand a command as such, and man cannot give them natural inclinations (e.g., it would be foolish to make a law for cats against the catching of birds).
294. The laws to be considered in the pages that follow are temporal and moral. Thus: (a) they are laws promulgated at some particular time, either from the beginning of humanity (as is the case with the Natural Law) or later (e.g., the Mosaic Law, the Christian Law, etc,); (b) they are laws regulating, not the necessary (as is the case with metaphysical or mathematical laws), but the contingent; (c) they are laws given, not to the irrational creature (as is the case with physical and biological laws), but to the rational, that it may attain its end through self-government in accordance with law.
Art. 2: THE NATURAL LAW
(Summa Theologica, I-II, qq. 93, 94.)
295. Meaning.—The Natural Law is so called for the following reasons: (a) it is received by man, not through special promulgation, but along with his rational nature. Hence, St. Paul says that the Gentiles, who had not received the laws specially promulgated, were a law unto themselves, that is, through their rational nature (Rom., ii. 14); (b) it includes only such precepts as can be known or deduced from the very nature of man, and thus some pagans fulfilled the Law of Moses naturally, i.e., as regards its natural precepts (Rom., ii. 14); (c) it can be known from the natural light of reason without instruction, being a law written on the heart of man (Rom, ii. 15).
The Natural Law is defined theologically as a participation of the Eternal Law in man. Three elements constitute its essence in its integrity: (a) a passive participation of the Eternal Law consisting in man's nature and faculties with their inclinations to their proper acts and ends. This man shares with all creatures. (b) an active participation in the Eternal Law proper to man. This consists in the activity of man's intellect through which he shares in God's providence and government in a special way as one who can rule himself and others. Reason, reflecting upon the natural inclinations and ordering them to their proper acts and ends, formulates (c) a dictate or command of the practical reason. This command constitutes the essence of Natural Law. "Hence the Psalmist after saying (Psalm, IV. 6): Offer up the sacrifice of justice, as though some one asked what the works of justice are, adds: Many say, Who showeth us good things, in answer to which he says: The light of thy countenance, 0 Lord, is signed upon us. Thus the Psalmist implies that the light of natural reason, whereby we discern what is good and bad, which is the function of the Natural Law, is nothing else than an imprint on us of the divine light. It is therefore evident that the Natural Law is nothing else than the rational creature's participation in the eternal law" (Summa Theol. I-II, q. 91, a.2).
296. Relation of the Natural Law to Other Laws.-(a) The Natural Law is inferior to the Eternal Law; for, while the Eternal Law exists in the mind of God, underived from any other law and is regulative of all created things, the Natural Law exists in the mind of man, as a derivation and image of the Eternal Law and a rule for man's acts only. (b) It is superior to Positive Law, for all Positive Law is a deduction from or a determination of Natural Law.
297. Division.—Since Natural Law is the reflection of the eternal plan of Divine Wisdom in the reason of man, we cannot distinguish different species of it according to difference of lawgivers or subjects. The objects regulated are, however, different; and hence we may distinguish various precepts of Natural Law.
(a) According to the difference of persons to whom natural duties are owed, there are natural laws concerning God (e.g., that God must be honored), natural laws concerning self (e.g., that one must not commit suicide), and natural laws concerning the neighbor (e.g., that injustice must not be done).
(b) According to the difference of natural inclinations in man, there are, first, natural laws common to him with all beings (e.g., the law of self-preservation, and hence it is a natural duty of man to take sleep, food, drink, remedies, etc., as necessary for life); secondly, natural laws common to him with all sentient beings or animals (e.g., the law of preservation of the species, and hence it is a natural duty of man to rear and provide for his children); thirdly, natural laws proper to man as a rational being (e.g., the laws that he should cultivate his powers of mind and will, and hence it is a natural duty of man to further religion and education, and to organize into societies and to respect the rights of others).
298. According to their necessity for the primary or the secondary end of a natural inclination, the laws of nature are divided into primary and secondary. (a) The primary end of a natural inclination is the conservation of a natural good; and so it is a primary law of nature that man should take the food, drink, sleep and exercise necessary for life, and that he should avoid poison or other things that cause death. (b) The secondary end of a natural inclination is the betterment of a natural good, or its easier conservation; thus, it is a secondary law of nature that man should use those kinds of food or drink that promote his health, that he should be careful about his diet, practise moderation, etc.
