n. 1) standards of conduct derived from traditional moral principles (first mentioned by Roman jurists in the first century A.D.) and/or God's law and will. The biblical ten commandments, such as "thou shall not kill," are often included in those principles. Natural law assumes that all people believe in the same Judeo-Christian God and thus share an understanding of natural law premises. 2) the body of laws derived from nature and reason, embodied in the Declaration of Independence assertion that "all men are created equal, that they are endowed by their creator with certain inalienable Rights, that among these are Life, Liberty and the pursuit of happiness." 3) the opposite of "positive law," which is created by mankind through the state.
