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.
