Some of our most obvious words in a speech open up secret meanings under scrutiny,and this is one of them.
To begin with, we must recognize the distinction between inner and outerforce. The one is cause, the other effect. The one is spiritual, the other physical. In this important particular, animate force differs from inanimate force--the power of man, coming from within and expressing itself outwardly, is of another sort from the force of Shimose powder,which awaits some influence from without to explode it. However susceptive to outside stimuli, the true source of power in man lies within himself. This may seem like "mere psychology," but it has an intensely practical bearing on public speaking, as will appear.
