The first half of Vannevar Bush’s Modern Arms and Free Men (1949) is a straightforward explanation of the progress made in military technology since 1918. This is the “Modern Arms” part of the book: Bush wants to be certain the reader understands recent developments before he tackles what they mean for “Free Men.” He is careful not to alienate readers without an existing grasp of the subject, and he also seems to step very carefully in establishing his authority: “For ten years,” he writes, “thanks to the accidents that direct men’s lives in a democracy, I was in a position to see as much as any single man could see… It is part of the obligation of any citizen who has been given such responsibility and opportunity as I have, no matter by what accident, to set down for the record what he has learned, and to share with others any light it may throw on the great question of war or peace that haunts us all.” In the second half of the book, he ruminates on democracy and the coming Cold War, as well as on the influence of modern military technology on both issues.
In general, Bush comes across as a technocrat who believes that scientifically trained experts can and must have a disproportionate influence on national policy, particularly as the United States continues to face off against totalitarian powers like the Soviet Union. But this technocracy and elitism is tempered by a democratic idealism that seems to rely on alchemy, a faith in a political process that works in eldritch ways to make everything turn out for the best.
