The Bible calls the good man's life a light, and it is the nature of light to flow out spontaneously in all directions, and fill the world unconsciously with its beams. So the Christian shines, it would say, not so much because he will, as because he is a luminous object. Not that the active influence of Christians is made of no account in the figure, but only that this symbol of light has its propriety in the fact that their unconscious influence is the chief influence, and has the precedence in its power over the world. And yet, there are many who will be ready to think that light is a very tame and feeble instrument, because it is noiseless. An earthquake, for example, is to them a much more vigorous and effective agency. Hear how it comes thundering through solid foundations of nature. It rocks a whole continent. The noblest works of man—cities, monuments, and temples—are in a moment leveled to the ground, or swallowed down the opening gulfs of fire. Little do they think that the light of every morning, the soft, and genial, and silent light, is an agent many times more powerful. But let the light of the morning cease and return no more, let the hour of morning come, and bring with it no dawn; the outcries of a horror-stricken world fill the air, and make, as it were, the darkness audible. The beasts go wild and frantic at the loss of the sun. The vegetable growths turn pale and die. A chill creeps on, and frosty winds begin to howl across the freezing earth. Colder, and yet colder, is the night. The vital blood, at length, of all creatures, stops congealed. Down goes the frost toward the earth's center. The heart of the sea is frozen; nay, the earthquakes are themselves frozen in, under their fiery caverns. The very globe itself, too, and all the fellow planets that have lost their sun, are become mere balls of ice, swinging silent in the darkness. Such is the light, which revisits us in the silence of the morning. It makes no shock or scar. It would not wake an infant in his cradle. And yet it perpetually new creates the world, rescuing it each morning, as a prey, from night and chaos. So the Christian is a light, even "the light of the world," and we must not think that, because he shines insensibly or 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.
Then if we go to others, that is, to the subjects of influence, we find every man endowed with two inlets of impression; the ear and the understanding for the reception of speech, and the sympathetic powers, the sensibilities or affections, for tinder to those sparks of emotion revealed by looks, tones, manners and general conduct. And these sympathetic powers, tho not immediately rational, are yet inlets, open on all sides, to the understanding and character. They have a certain wonderful capacity to receive impressions, and catch the meaning of signs, and propagate in us whatsoever falls into their passive molds from others. The impressions they receive do not come through verbal propositions, and are never received into verbal propositions, it may be, in the mind, and therefore many think nothing of them. But precisely on this account are they the more powerful, because it is as if one heart were thus going directly into another, and carrying in its feelings with it. Beholding, as in a glass, the feelings of our neighbor, we are changed into the same image, by the assimilating power of sensibility and fellow-feeling. Many have gone so far, and not without show, at least, of reason, as to maintain that the look or expression, and even the very features of children, are often changed by exclusive intercourse with nurses and attendants. Furthermore, if we carefully consider, we shall find it scarcely possible to doubt, that simply to look on bad and malignant faces, or those whose expressions have become infected by vice, to be with them and become familiarized to them, is enough permanently to affect the character of persons of mature age. I do not say that it must of necessity subvert their character, for the evil looked upon may never be loved or welcomed in practise; but it is something to have these bad images in the soul, giving out their expressions there, and diffusing their odor among the thoughts, as long as we live. How dangerous a thing is it, for example, for a man to become accustomed to sights of cruelty? What man, valuing the honor of his soul, would not shrink from yielding himself to such an influence? No more is it a thing of indifference to become accustomed to look on the manners, and receive the bad expression of any kind of sin.
The door of involuntary communication, I have said, is always open. Of course we are communicating ourselves in this way to others at every moment of our intercourse or presence with them. But how very seldom, in comparison, do we undertake by means of speech to influence others! Even the best Christian, one who most improves his opportunities to do good, attempts but seldom to sway another by voluntary influence, whereas he is all the while shining as a luminous object unawares, and communicating of his heart to the world.
But there is yet another view of this double line of communication which man has with his fellow-men, which is more general, and displays the import of the truth yet more convincingly. It is by one of these modes of communication that we are constituted members of voluntary society, and by the other, parts of a general mass, or members of involuntary society. You are all, in a certain view, individuals, and separate as persons from each other; you are also, in a certain other view, parts of a common body, as truly as the parts of a stone. Thus if you ask how it is that you and all men came without your consent to exist in society, to be within its power, to be under its laws, the answer is, that while you are a man, you are also a fractional element of a larger and more comprehensive being, called society—be it the family, the church, the state. In a certain department of your nature, it is open; its sympathies and feelings are open. On this open side you will adhere together, as parts of a larger nature, in which there is a common circulation of want, impulse, and law. Being thus made common to each other voluntarily, you become one mass, one consolidated social body, animated by one life. And observe how far this involuntary communication and sympathy between the members of a state or a family is sovereign over their character. It always results in what we call the national or family spirit; for there is a spirit peculiar to every state and family in the world. Sometimes, too, this national or family spirit takes a religious or an irreligious character, and appears almost to absorb the religious self-government of individuals. What was the national spirit of France, for example, at a certain time, but a spirit of infidelity? What is the religious spirit of Spain at this moment, but a spirit of bigotry, quite as wide of Christianity and destructive of character as the spirit of falsehood? What is the family spirit in many a house, but the spirit of gain, or pleasure, or appetite, in which everything that is warm, dignified, genial, and good in religion, is visibly absent? Sometimes you will almost fancy that you see the shapes of money in the eyes of children. So it is that we are led on by nations, as it were, to good or bad immortality. Far down in the secret foundations of life and society there lie concealed great laws and channels of influence, which make the race common to each other in all the main departments or divisions of the social mass, laws which often escape our notice altogether, but which are to society as gravity to the general system of God's works.
But these are general considerations, and more fit, perhaps, to give you a rational conception of the modes of influence and their relative power, than to verify that conception, or establish its truth. I now proceed to add, therefore, some miscellaneous proofs of a more particular nature.
And I mention, first of all, the instinct of imitation in children. We begin our mortal experience, not with acts grounded in judgment or reason, or with ideas received through language, but by simple imitation, and, under the guidance of this, we lay our foundations. The child looks and listens, and whatsoever tone of feeling or manner of conduct is displayed around him, sinks into his plastic, passive soul, and becomes a mold of his being ever after. The very handling of the nursery is significant, and the petulance, the passion, the gentleness, the tranquillity indicated by it, are all reproduced in the child. His soul is a purely receptive nature, and that for a considerable period, without choice or selection. A little further on he begins voluntarily to copy everything he sees. Voice, manner, gait, everything which the eye sees, the mimic instinct delights to act over. And thus we have a whole generation of future men, receiving from us their beginnings, and the deepest impulses of their life and immortality. They watch us every moment, in the family, before the hearth, and at the table; and when we are meaning them no good or evil, when we are conscious of exerting no influence over them, they are drawing from us impressions and molds of habit, which, if wrong, no heavenly discipline can wholly remove; or, if right, no bad associations utterly dissipate. Now it may be doubted, I think, whether, in all the active influence of our lives, we do as much to shape the destiny of our fellow-men as we do in this single article of unconscious influence over children.
Still further on, respect for others takes the place of imitation. We naturally desire the approbation or good opinion of others. You see the strength of this feeling in the article of fashion. How few persons have the nerve to resist a fashion! We have fashions, too, in literature, and in worship, and in moral and religious doctrine, almost equally powerful. How many will violate the best rules of society, because it is the practise of the circle! How many reject Christ because of friends or acquaintance, who have no suspicion of the influence they exert, and will not have, till the last days show them what they have done! Every good man has thus a power in his person, more mighty than his words and arguments, and which others feel when he little suspects it. Every bad man, too, has a fund of poison in his character, which is tainting those around him, when it is not in his thoughts to do them injury. He is read and understood. His sensual tastes and habits, his unbelieving spirit, his suppressed leer at religions, have all a power, and take hold of the heart of others, whether he will have it so or not.
Again, how well understood is it that the most active feelings and impulses of mankind are contagious. How quick enthusiasm of any sort is to kindle, and how rapidly it catches from one to another, till a nation blazes in the flame! In the case of the Crusades you have an example where the personal enthusiasm of one man put all the states of Europe in motion. Fanaticism is almost equally contagious. Fear and superstition always infect the mind of the circle in which they are manifested. The spirit of war generally becomes an epidemic of madness, when once it has got possession of a few minds. The spirit of party is propagated in a similar manner. How any slight operation in the market may spread, like a fire, if successful, till trade runs wild in a general infatuation, is well known. Now, in all these examples, the effect is produced, not by active endeavor to carry influence, but mostly by that insensible propagation which follows, when a flame of any kind is once more kindled.
