Natural moral law provides a framework for evaluating the ethics... Show more

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:
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:
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.

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:
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:
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.

This app has made me feel so much more confident in my exam prep, not only through boosting my own self confidence through the features that allow you to connect with others and feel less alone, but also through the way the app itself is centred around making you feel better. It is easy to navigate, fun to use, and helpful to anyone struggling in absolutely any way.

I know a lot of apps use fake accounts to boost their reviews but this app deserves it all. Originally I was getting 4 in my English exams and this time I got a grade 7. I didn’t even know about this app three days until the exam and it has helped A LOT. Please actually trust me and use it as I’m sure you too will see developments.
