Impulse and Vibration
Having got these relative proportions well in our minds we may for a brief time give our attention to an important scientific fact which is necessary to our study. Our lives are entirely controlled by impulses which originate in various parts of our personalities. Sometimes the impulse comes from our bodies; again the feelings are in control, and at times the memory asserts itself. Then again the intellect is the dominating factor. Of this we may be sure, from whatever element of being comes the strongest impulse, there for the time being is the seat of government. We are also scientifically certain, that the more finely attenuated an impulse is, and the more rapid the vibrations are which carry such an impulse, the more powerful it is and the more surely will it prevail over the slower impulses carried at a lower rate of vibration. A current of electricity of high voltage will melt a bar of steel.
