"Decades later, when Spruance's military and diplomatic career had become history, Spruance was generally regarded as a man endowed with extraordinary intelligence and proven wisdom. Whether he was an intellectual is debatable. Intellectuals are commonly associated with the pursuit of the liberal arts and the physical sciences, with advanced academic degrees, and with learned writing and speaking. As a distinguished author recently observed, "In common parlance an intellectual is a man soaked in the advanced critical ideas of the liberal-academic establishment; and even an opponent of these ideas... has them all at his fingertips." Using these standards alone, Spruance would not be regarded as an intellectual. His formal education ended at the Naval Academy, and he read few, if any, of the classic works in science, literature, and philosophy. He disliked writing, and what little he wrote was not for publication. He also disliked public speaking, and what few speeches he did make were soon forgotten. Nevertheless, Spruance was an intellectual in the purest sense of the word. He was a person with superior mental power. He was deeply interested in fields of knowledge outside the technicalities of the naval profession. He once told some university students, "I think it is most desirable for you to retain and to stimulate your intellectual curiosity in other fields where you may have a natural interest." He explained that those with a liberal education in art, literature, and music had an advantage over people- such as himself- with only a technical education. "A knowledge and appreciation of these subjects enriches their lives," he said, "and makes them more interesting individuals to their friends and acquaintances." Finally, Spruance was a classic intellectual in the sense that he was extremely rational and relied upon his intellect rather than his emotions or feelings. He later regarded the war against Japan as an intellectual exercise that posed a complex yet interesting series of problems that challenged and stimulated his mind. These problems had to be solved using logic and reason that was unaffected by the violent passions of war."
