"The difference between science and the fuzzy subjects is that science requires reasoning while those other subjects merely require scholarship"
About this Quote
Heinlein draws a bright line between science and what he dismissively calls fuzzy subjects, elevating the habit of disciplined inference over the accumulation of facts. The snap of the sentence lies in the word merely. He frames scholarship as passive hoarding of authorities and citations, while science is cast as the active exercise of logic, experiment, and hypothesis testing. The jab reflects a mid-20th-century confidence in technocratic rationality and an engineer’s impatience with fields that cannot settle questions by measurement. It also echoes the era’s Two Cultures debate described by C. P. Snow, where scientists and humanists seemed to inhabit incompatible intellectual worlds.
Yet the dichotomy is more rhetorical than real. Science runs on scholarship: literature reviews, methodological training, replication archives, and a tacit knowledge of what counts as a good question. Darwin’s reading of Malthus mattered as much as his fieldwork. Likewise, the so-called fuzzy subjects do not merely catalog facts. Philosophy, history, and literary studies revolve around argument, inference, and the weighing of evidence, albeit evidence that is often qualitative, context-dependent, and resistant to clean quantification. Social sciences have also created rigorous toolkits for reasoning under uncertainty: statistics, causal inference, survey design, and field experiments.
Heinlein’s provocation still does useful work if it is taken as a warning against rote learning and credentialism. Reasoning should trump memorization in every discipline. But treating fuzziness as a flaw risks mistaking the object of study for a lack of rigor. Human affairs are noisy, value-laden, and path-dependent; they require forms of reasoning that are less about control and more about interpretation and judgment.
A better synthesis honors both virtues. Scholarship preserves, contextualizes, and transmits the accumulated record; reasoning interrogates it, refines it, and sometimes overturns it. The strongest sciences are scholarly, and the strongest humanities are exacting in their logic. Education that cultivates both habits equips us to navigate complexity, whether in a lab, a court, or a public square awash in unvetted claims.
