A good statement of an inherently imprecise concern - and most important concerns in the world are imprecise - must capture that imprecision, and not replace it by a precise statement about something else. You should learn to speak in an articulate way about ideas that are inescapably imprecise (as a man called Aristotle explained more than two millennia ago). And that is one of the reasons why the humanities are important. A novel can point to a truth without pretending to capture it exactly in some imagined numbers and formulae.
