precept

A rule is a rule or direction that usually has religious grounds that determine how to act and act.

Discipline is a small life course usually taught to children by authorities such as parents, teachers, religious figures. They are not as simple or practical as "eat your vegetables"; they tend to be heavier and exaggerated. In Hamlet, the character "Polonius" casts some options to his son Rirtis "not borrowers or lenders" or "listen to everyone", but your voice is very small. "Of course, Hamlet killed him with his own poison blade, so Laertes did not live long enough to benefit from the holy advice of Polonius."

The main rule "to protect innocent human life" leads to secondary rules such as "do not stop" or "do not euthanasia". Secondary discipline comes from the main rules; theoretically, they are easier to explain than the main rules. Aquinas allows you to create detailed information about them, such as coping with the situation. There are even more exceptions. Natural law also examines the function of individual body parts related to our overall purpose. I believe that Aquinas is wrong to use something other than other functions and purposes; the purpose of the genitals is breeding, contraception is incorrect. Trivial precepts do not obey the main rules directly, they need good judgment and wisdom to accomplish. When there was a reason to ask, Aquinas permitted the change of the second commandment, he called the killing in war "the smaller of two evils".

Natural law consists of the rule of the eternal law which dominates the behavior of existence with reason and free will. According to Aquinas, the first rule of natural law is to do good and avoid somewhat empty demands of evil. It is worth noting that Aquinas has a moral theory of natural law. According to Aquinas, good and evil are derived from the rational nature of human beings. So good and evil are objective and universal. However, Aquinas is also a legal theorist of natural law. In his view, human laws (ie, laws enacted by humans) are effective only when their content is consistent with the content of natural law. It comes from the law of nature, but if it deviates from the law of nature, it is no longer a law but a perverted law "(ST I - II, Q. 95, A. II)
