As a speechwriter for Barry Goldwater, Hess explored ideology and politics and attracted some public interest. He was widely considered to be the author of the infamous Goldwater line, "Extremism in the defense of liberty is no vice; moderation in the pursuit of justice is no virtue," but revealed that he had encountered it in a letter from Lincoln historian Harry Jaffa and later learned it was a paraphrase of a passage from Cicero.
