What's the difference between the natural law and the laws of nature?


Full Question

Catholic moral theologians talks about the natural law, and scientists talk about the laws of nature, but they don't seem to be talking about the same thing. What is the difference between natural law and the laws of nature?

Answer

Pope John Paul answered this question nicely in his encyclical Veritatis Splendor. He said the natural law of moral theology "receives this name not because it refers to the nature of irrational things but because the reason which promulgates it is proper to human nature" (VS 42). The moral law is called natural law because it is based on our nature as rational beings. It is not based on the nature of irrational beings, such as animals, plants, or inanimate matter. When scientists refer to the laws of nature, they mean physical laws such as the law of gravity or the laws of thermodynamics.
