The law of nature is that which God, the sovereign of the universe, has prescribed to all men, not by any formal promulgation, but by the internal dictate of reason alone. It is discovered by a just consideration of the agreeableness or disagreeableness of human actions to the nature of man; and it comprehends all the duties which we owe either to the Supreme Being, to ourselves, or to our neighbors; as reverence to God, self-defence, temperance, honor to our parents, benevolence to all, a strict adherence to our engagements, gratitude, and the like. 2. The primitive laws of nature may be reduced to six, namely: 1. Comparative sagacity, or reason. 2. Self-love. 3. The attraction of the sexes to each other. 4. The tenderness of parents towards their children. 5. The religious sentiment. 6. Sociability.
