“The enemy—the indispensible devil of every mass movement—is omnipresent. He plots both outside and inside the ranks of the faithful. It is his voice that speaks through the mouth of the dissenter, and the deviationists are his stooges. If anything goes wrong within the movement, it is his doing. It is the sacred duty of the true believer to be suspicious. He must be constantly on the lookout for saboteurs, spies and traitors.”
― Eric Hoffer, The True Believer: Thoughts on the Nature of Mass Movements
