What is Natural Law and Abortion: A Simple Essay

Catholic Church's Stance on Abortion
This page delves deeper into the Catholic Church's position on abortion, exploring the application of natural moral law and the principle of double effect in specific scenarios.
Principle of Double Effect:
- Allows for indirect abortion in limited circumstances
- Example: A woman with a life-threatening pregnancy
Example: A woman with a cancerous uterus may undergo a hysterectomy to save her life, even if it results in the death of the fetus. This is permissible because:
- Removing a cancerous uterus is morally good
- The fetus' death is an unintended side-effect
- The fetus' death is not the means of saving the woman's life
- Saving the woman's life is at least as morally significant as saving the fetus
Biblical Basis: The Catholic stance on abortion is rooted in the sanctity of life principle derived from Genesis 1:26-27, which states that human life is sacred as it is created in God's image.
Highlight: The Catholic Church maintains a strict stance on abortion, allowing no exceptions even in cases of rape or incest.
Vocabulary: Sanctity of Life - the principle that human life is sacred and inviolable, often used in religious and ethical arguments against abortion.
Definition: Principle of Double Effect - a moral principle that distinguishes between the intended and unintended consequences of an action, used to evaluate the ethics of actions that have both good and bad effects.

Applying Natural Moral Law to Abortion
Natural moral law offers a philosophical and theological approach to analyzing the ethics of abortion, particularly from a Catholic perspective. This page examines Aquinas' writings on fetal development and applies natural law principles to the abortion debate.
Aquinas' Views on Fetal Development:
- Believed a human person with a rational soul is present 60-80 days after conception
- Opposed abortion after this point, considering it homicide
Quote: "He that strikes a woman with child does something unlawful: wherefore if there results the death either of the woman or of the animated foetus, he will not be excused from homicide, especially seeing that death is the natural result of such a blow."
Applying Primary Precepts: Abortion at any stage violates all five tests of Aquinas' natural moral law:
- Violates the principle of defending innocent life (the fetus)
- Violates the precept of worshipping God by destroying His creation
Highlight: The Catholic Church reinforces natural moral law by forbidding abortion at any stage, except in rare cases through the principle of double effect.
Vocabulary: Primary Precepts - fundamental moral principles in natural law theory that guide ethical decision-making.
Definition: Natural Moral Law - an ethical theory that posits the existence of universal moral principles derived from reason and human nature.

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.
This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.
Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.
