What happens when a man elevates his mind beyond all others? John Wanniston isn't content with average intelligence. He finds a machine that energizes the brain, pushing his intellect to superhuman heights. But as his mental powers grow, so does his distance from the human race. He begins to manipulate those around him, convinced that his superior mind entitles him to control. The tragedy unfolds quietly: every gain in understanding costs him something essential. His former friends become pawns. His humanity becomes an inconvenience. By the time he recognizes what he's lost, the distance is insurmountable. Written in 1946, this is one of the earliest SF explorations of the super-intelligence theme, and it remains unsettling because it understands something most stories miss: the danger isn't the machine, it's the loneliness of standing above everyone else.
