The theorist most associated with natural law ethics is ___________.

• A. Immanuel Kant
• B. St Thomas Aquinas
• C. Aristotle
• D. John Rawls

Answer: (B)

Natural law ethics holds that moral judgments flow from human nature and the use of reason to discern the goods that human flourishing requires. In this view, there are objective standards of right and wrong that can be grasped by reason about what is conducive to living well, ratherizing life, procreation and education of offspring, seeking knowledge, living peacefully in society, and ultimately honoring the divine. Law, then, is seen as rational guidance deriving from our participation in a preexisting moral order. St Thomas Aquinas is the figure most closely tied to this approach because he systematized natural law within a Christian framework and showed how reason can uncover universal precepts from human nature. He explains that there is an eternal law (God’s order), and humans participate in it through natural law, which is accessible to rational creatures without requiring revelation for basic truths. From these precepts flow concrete moral norms and duties, explaining why certain actions are right or wrong across cultures. While other philosophers have influential ideas about morality—Aristotle as a predecessor who emphasized natural teleology, Kant with his rational-world duties, or Rawls with justice as fairness—the tradition most associated with natural law ethics as a distinct framework is Aquinas’s.
