Below are four books on persuasion you may not have considered. I recommend them all.
Political Warfare Against the Kremlin: US and British Propaganda Policy at the Beginning of the Cold War by Lowell Schwartz. Strongly recommended if you’re interested in a relevant past ideological struggle. We cannot afford to ignore our past, especially when they had such a better grip on the requirements than we seem to have today.
In Search of a Usable Past: The Marshall Plan and Postwar Reconstruction Today by Barry Machado. Reading about the “psychological by-products” of post-conflict reconstruction is something many would be wise to do today.
Propaganda by Edward Bernays. Originally published in 1928, it is frank discussion of the reality of persuasion using the corporate world as examples. Modern propaganda, Bernays wrote, “is a consistent, enduring effort to create or shape events to influence the relations of the public to an enterprise, idea or group.”
The Just Prince: A Manual of Leadership edited by Joseph Kechichian. We continue to operate as if we are in a Machiavellian world, but we’re not. Written from an Arab-Muslim perspective nearly 350 years before the Florentine clerk wrote The Prince, the Just Prince arrives at similar ends as Machiavelli but the different views of power and authority creates different means to those ends.
