Understanding Aquinas' Natural Law - WJEC Ethics Theme 2




Natural Law Foundations
Natural Law rests on the idea that humans possess reason as an innate ability to discern good from evil. This reasoning ability, though fallible (unlike divine reasoning which is infallible), helps us identify our proper purpose and align with God's eternal law.
The framework has a hierarchical structure with Eternal Law at the top—representing God's wisdom and will governing the universe. Natural Law flows from this, representing the moral principles discoverable through human reason. Aquinas includes the Synderesis rule, the fundamental principle that reason directs us to pursue good and avoid evil.
Divine Law (found in scripture) complements Natural Law because human reasoning alone is imperfect. The ultimate purpose of following Natural Law is to achieve the Beatific Vision—restoring our relationship with God damaged by the Fall and gaining eternal life.
💡 Think of Natural Law as your moral compass that's built into your reasoning ability. Unlike human laws that change with governments, Natural Law reflects unchanging moral truths derived from God's eternal design.

Intention, Acts, and Virtues
In Natural Law, both interior acts (intention) and exterior acts (the actions themselves) matter. This deontological approach means actions are intrinsically good or bad regardless of consequences. Good intentions don't redeem inherently wrong actions—stealing for a friend in need remains morally wrong.
Aquinas distinguishes between real goods (actions aligned with reason that help reach our true purpose) and apparent goods (actions that seem good but misuse reason and don't fulfill our purpose). The principle of double effect explains how an action with unintended side effects can still be moral if the primary intention is good.
The Cardinal virtues serve as the hinges of a moral life: prudence (being sensible), courage (discipline facing adversity), temperance , and justice (fairness toward others). These work alongside the revealed virtues from St. Paul: faith (active choice of will), hope (desire for fellowship with God), and love (the greatest virtue that restores our fallen nature).
🔑 As Aquinas said, "What things that we love tell us what we are." Your character is shaped by what you consistently choose and value—your virtues reveal your true self.

Natural Law Applied: Abortion and Euthanasia
Natural Law's principle of the preservation of life directly impacts debates on abortion and euthanasia. While UK law allows abortion up to 24 weeks (and later in cases of severe disability), Catholic interpretation of Natural Law generally opposes abortion as contrary to the sanctity of life and the precept "thou shall not kill."
Catholic theologian Kainz acknowledged the complexity of abortion ethics, suggesting that while virtuous Christians might continue pregnancies even in difficult cases, considerations beyond preservation of life (such as rights to nurture) are also relevant. Biblical passages like Genesis 1:28 ("Be fruitful, multiply") and Psalm 139 inform Christian perspectives.
Regarding euthanasia, which remains illegal in the UK, Natural Law considerations include the "slippery slope" argument—that permitting euthanasia might eventually lead to terminating lives of those unable to consent. Mill's perspective offers a contrasting view, arguing for bodily autonomy as long as no harm comes to others.
⚖️ Natural Law doesn't just provide black and white answers on complex ethical issues—it offers a framework for reasoning through difficult questions while keeping human purpose and divine design in view.
