In this way the number of convinced adherents of the persecuted doctrine increases as the persecution progresses. Hence the total destruction of a new doctrine can be accomplished only by a vast plan of extermination; but this, in the final analysis, means the loss of some of the best blood in a nation or State. And that blood is then avenged, because such an internal and total clean-up brings about the collapse of the nation's strength. And such a procedure is always condemned to futility from the very start if the attacked doctrine should happen to have spread beyond a small circle.
