Natural law theory in ethics asserts that human beings possess intrinsic values that fundamentally guide their reasoning and behavior. Rooted in philosophical and theological traditions, this theory argues that moral principles are inherent in human nature and can be discovered through reason.
Fundamental Principles of Natural Law
The core tenets of natural law theory include:
Human Nature and Moral Principles
According to natural law theory, moral principles are grounded in the nature of human beings. These principles are objective and universal, transcending cultural and temporal differences.
The Role of Reason
Reason plays a pivotal role in natural law theory. It is through rational reflection that individuals can discern the moral principles embedded in human nature.
Intrinsic Values
Natural law theory posits that humans have intrinsic values, such as the desire for life, reproduction, knowledge, and social interaction. These values form the basis for moral duties and rights.

The roots of natural law theory can be traced back to ancient Greek philosophers like Aristotle, who believed that natural justice was a part of the order of nature.
Medieval Philosophies
The theory was further developed by medieval philosophers such as Thomas Aquinas. Aquinas integrated Aristotelian philosophy with Christian theology, arguing that natural law is part of God’s eternal law.
