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.
