"The difference between science and the fuzzy subjects is that science requires reasoning while those other subjects merely require scholarship"
About this Quote
The subtext is less about defending science than policing status. “Fuzzy subjects” isn’t a neutral descriptor; it’s a preemptive dismissal, a way of making ambiguity sound like incompetence. By defining science as reasoning itself, Heinlein claims the universal high ground: if you disagree, you’ve already been assigned to the non-reasoning camp. It’s a neat trick, and a very writerly one, especially from an author who built careers on ideas that needed both logical scaffolding and imaginative seduction.
Context matters: mid-century America lionized STEM as the motor of national power (Cold War, space race, technocracy), while treating the humanities as either moral window dressing or political troublemaking. Heinlein, steeped in that moment’s confidence about technology and systems, is voicing a broadly felt impatience with academic gatekeeping and obscurantism.
The irony, of course, is that scholarship is reasoning with receipts, and science at its best is also interpretation: choosing models, arguing significance, negotiating uncertainty. Heinlein’s quip works because it’s unfair in a satisfying way - a slogan for people who want clarity, and an excuse to ignore the kinds of questions that don’t yield to equations.
