silently, as a mere luminous object, he is therefore powerless. The greatest powers are ever those which lie back of the little stirs and commotion of nature; and I verily believe that the insensible influences of good men are much more potent than what I have called their voluntary, or active, as the great silent powers of nature are of greater consequence than her little disturbances and tumults. The law of human influences is deeper than many suspect, and they lose sight of it altogether. The outward endeavors made by good men or bad to sway others, they call their influence; whereas, it is, in fact, but a fraction, and, in most cases, but a very small fraction, of the good or evil that flows out of their lives. Nay, I will even go further. How many persons do you meet, the insensible influence of whose manners and character is so decided as often to thwart their voluntary influence; so that, whatever they attempt to do, in the way of controlling others, they are sure to carry the exact opposite of what they intend! And it will generally be found that, where men undertake by argument or persuasion to exert a power, in the face of qualities that make them odious or detestable, or only not entitled to respect, their insensible influence will be too strong for them. The total effect of the life is then of a kind directly opposite to the voluntary endeavor, which, of course, does not add so much as a fraction to it. I call your attention, next, to the twofold powers of effect and expression by which man connects with his fellow man. If we distinguish man as a creature of language, and thus qualified to communicate himself to others, there are in him two sets or kinds of language, one which is voluntary in the use, and one that is involuntary; that of speech in the literal sense, and that expression of the eye, the face, the look, the gait, the motion, the tone of cadence, which is sometimes called the natural language of the sentiments. This natural language, too, is greatly enlarged by the conduct of life, that which, in business and society, reveals the principles and spirit of men. Speech, or voluntary language, is a door to the soul, that we may open or shut at will; the other is a door that stands open evermore, and reveals to others constantly, and often very clearly, the tempers, tastes, and motives of their hearts. Within, as we may represent, is character, charging the common reservoir of influence, and through these twofold gates of the soul pouring itself out on the world. Out of one it flows at choice, and whensoever we purpose to do good or evil to men. Out of the other it flows each moment, as light from the sun, and propagates itself in all beholders.
