The problem of the laws of nature has been brought to the forefront by no less than David Hume himself. The skeptic that he was, Hume brought forth the regularity theory of laws, coined the Humean Theory. In the Humean Theory, Laws of Nature are statements of the uniformities (regularities) in the world. It denies the necessity of any objective causality appearing in a law. On the other hand, we have a metaphysical necessity put forth by Hilary Putnam which states that laws get their reference fixed in the actual work by means of archetypal specimens.
