What are those things we call “laws of nature”?

by Neil Rickert

There was a recent post at Aeon by philosopher Marc Lang:

I want to discuss that, and to discuss some of my disagreements. My first disagreement, is that I don’t believe there are such things as laws of nature. But there are certainly things that people call “laws of nature”. I’m okay with calling them scientific laws. But I doubt that they come from nature. That is to say, I see these laws as human constructs. I do not see them as something that we can just read from nature itself.

In our science classes, we all learned some examples of what scientists currently believe (or once believed) to be laws of nature. Some of these putative laws are named after famous scientists (such as Robert Boyle and Isaac Newton). Some are generally called ‘laws’ (such as the laws of motion and gravity), while others are typically called ‘principles’ (such as Archimedes’ principle and Bernoulli’s principle), ‘rules’ (such as Born’s rule and Hund’s rule), ‘axioms’ (such as the axioms of quantum mechanics), or ‘equations’ (such as Maxwell’s equations).

It is interesting to note the expression “what scientists currently believe (or once believed) to be laws of nature” for that already suggests that scientists can change their minds as to what they take to be laws of nature. And this seems to agree with my point that these laws are actually human constructs.
