  • Preceptive part includes general rules such as "Do good" and "Avoid evil."
  • It is based on reason, which is innate to all humans.
  • Natural moral law is known through conscience, which is an innate sense of right and wrong that guides our actions.
  • Natural Moral Law is a deontological theory
  • Deontology focuses on the morality of actions rather than their consequences
  • NML context
    Thomas Aquinas - 13th century Catholic priest. As a Catholic, Aquinas believed in the authority of the church and the bible
  • Syndersis principle
    Act in a way that does good and avoids evil
  • Primary and secondary precepts
    Worship God
    Ordered society
    Reproduce
    Learn
    Defend the innocent/preserve life
    Secondary precepts are derived from the primary precepts
  • Manualism
    17th century creation. Made NML more deontological. Big manuals of secondary precepts
  • Proportionalism
    Created by Hoose and McCormick. They agreed that sometimes, the primary precepts can lead to unloving outcomes. Sometimes, it is acceptable to break the precepts in order for a more loving outcome. 20th century movement.
  • The doctrine of double effect
    Aquinas did acknowledge that there would be times when a person could follow the precepts but still end up breaking them. For example, if a pregnant woman with cancer was to receive chemotherapy, but the baby got killed in the process, it would come under 'preserving life' because you were trying to preserve the life of the mother, and the miscarriage is just a secondary effect. Aquinas argues that you've done nothing wrong.
  • Strengths of NML
    Helps to establish rules that people can follow in society
    Universal system as it relies on reason
    The precepts are commonly accepted
    Supports human rights and equality
    Allows people to stand firm on moral issues
    Secondary precepts act as a guide for moral right and wrong
    Related to human nature
  • Weaknesses of NML
    Reason is not universal, other cultures have different standards
    It is outdated
    Not everyone believes in God
    Aquinas should've got some of his assumptions wrong in the body
    Aquinas' account of nature is way too simplistic
  • NML and Abortion
    To save the life of the mother due to double effect
    Life begins at conception. Preserve life is a primary precept. Do not kill is a secondary precept. Catholic tradition teaches that abortion is always wrong
  • NML and Embryo research 

    Can be used to preserve life
    Life begins at conception, so the embryo is already considered human. Any research that discards embryos is murder. Reproduction should be natural
  • NML and euthansia/assisted suicide
    Pain killing drugs may be administered to someone, which may have an accidental secondary effect
    Self-preservation is a primary precept
    Divine law outlaws suicide
    Catholic tradition says that suicide is an unforgivable sin
  • NML and Designer babies
    Can be used to preserve life in the form of a saviour sibling
    It is wrong to play God - goes against "worship God"
