Tap 1 – Claude M. Bristol – Magic of Believing
(An excerpt from the “Strangest Secret Library”)
First, however, permit me to set the stage by calling attention to the effect of repetition or reiteration. For example, take a pneumatic chisel - you have seen one used in breaking up solid concrete or piercing holes through steel. It's the tap, tap, tap, tap of that chisel with a terrific force behind which causes disintegration of the particles and makes a dent or hole in the object on which it is used.
All of us have heard of the old torture system of dripping water on the forehead. Perhaps you are familiar with Kipling's "Boots." It's the tramp, tramp of boots, boots, that makes men mad. It's the constant never-ending repetition that penetrates.
You are familiar with the first part of the picture and how repetition works on material things, but some of you may not thoroughly understand the second part, but here, too, it's the repetition that ultimately makes its impression upon the human mind.
