Iain King and Myles King contend that physics helps us understand ethics.

Criticising one of history’s most important-ever scientists can sound like a sketch from Monty Python: “OK, but apart from breakthroughs in optics, mathematics, mechanics, explaining gravity, inventing calculus, something about trigonometry, predicting how planets move, and other stuff that we don’t understand, what has Isaac Newton ever done for us?”

Newton’s work transformed science, and eventually, society. But Newton’s legacy comes with an ugly side: he inspired ‘physics envy’, which, in turn, led humanity to some truly dark places. ‘Physics envy’ is the desire to find Newtonian-type mathematical formulas or algebraic laws in other disciplines. Sometimes the endeavour is absurd, as when economists try to explain their economic opinions in algebraic equations. But when applied to psychology, history, class warfare, or evolution, thinkers with physics envy usually end up describing humans in dangerously oversimplified terms.
