But a solution of this problem, clearer perhaps than any other, appears when we consider another lesson of the street; a lesson which requires us to look a little deeper, but which, when we do look, is no less evident than these diversities. That lesson unfolds the essential unity of humanity. For, we find that the differences between men are formal rather than real; that, with various outward conditions, they pass through the same great trials; and that the scales which seem to hang uneven at the surface, and to be tipped this way and that by the currents of worldly fortune, are very nearly balanced in the depths of the inner life. We are shallow judges of the happiness or the misery of others, if we estimate it by any marks that distinguish them from ourselves; if, for instance, we say that because they have more money they are happier, or because they live more meagrely they are more wretched. For, men are allied by much more than they differ. The rich man, rolling by in his chariot, and the beggar, shivering in his rags, are allied by much more than they differ. It is safer, therefore, to estimate our neighbor's real condition by what we find in our own lot, than by what we do not find there. And now, see into what an essential unity this criterion draws the jostling, divergent masses in yonder street! Each man there, like all the rest, finds life to be a discipline. Each has his separate form of discipline; but it bears upon the kindred spirit that is in every one of us, and strikes upon motives, sympathies, faculties, that run through the common humanity. Surely, you will not calculate any essential difference from mere appearances; for the light laughter that bubbles on the lip often mantles over brackish depths of sadness, and the serious look may be the sober veil that covers a divine peace. You know that the bosom can ache beneath diamond brooches, and how many blithe hearts dance under coarse wool. But I do not allude merely to these accidental contrasts. I mean that about equal measures of trial, equal measures of what men call good and evil, are allotted to all; enough, at least, to prove the identity of our humanity, and to show that we are all subjects of the same great plan. You say that the poor man who passes yonder, carrying his burden, has a hard lot of it, and it may be he has; but the rich man who brushes by him has a hard lot of it too—just as hard for him, just as well fitted to discipline him for the great ends of life. He has his money to take care of; a pleasant occupation, you may think; but, after all, an occupation, with all the strain and anxiety of labor, making more hard work for him, day and night, perhaps, than his neighbor has who digs ditches or thumps a lapstone. And it is quite likely that he feels poorer than the poor man, and, if he ever becomes self-conscious, has great reason to feel meaner. And then, he has his rivalries, his competitions, his troubles of caste and etiquette, so that the merchant, in his sumptuous apartments, comes to the same essential point, "sweats, and bears fardels," as well as his brother in the garret; tosses on his bed with surfeit, or perplexity, while the other is wrapped in peaceful slumber; and, if he is one who recognizes the moral ends of life, finds himself called upon to contend with his own heart, and to fight with peculiar temptations. And thus the rich man and the poor man, who seem so unequal in the street, would find but a thin partition between them, could they, as they might, detect one another kneeling on the same platform of spiritual endeavor, and sending up the same prayers to the same eternal throne.

But, say you, ["here] is one who is returning to a home of destitution, of misery; where the light of the natural day is almost shut out, but in which brood the deeper shadows of despair." And yet, in many a splendid mansion you will find a more fearful destitution, a dearth of affections, killed by envy, jealousy, distrust; stifled by glittering formalities; a brood of evil passions that mock the splendor, and darken the magnificent walls. The measure of joy, too, is distributed with the same impartiality as the measure of woe. The child's grief throbs against the round of its little heart as heavily as the man's sorrow; and the one finds as much delight in his kite or drum, as the other in striking the springs of enterprise or soaring on the wings of fame. After all, happiness is the rule, not the exception, even in the hearts that beat in the crowded city; and its great elements are as common as the air, and the sunshine, and free movement, and good health. And what the fortunate may seem to gain in variety of methods, may only be unconscious devices to simulate or recover that natural relish which others have never lost. And no one doubts that the great dispensations of life, the events that make epochs in our fleeting years, cleave through all the strata of outward difference, and lay bare the core of our one humanity. Sickness! does it not make Dives look very much like Lazarus, and show our common weakness, and reveal the common marvel of this "harp of thousand strings?" And sorrow! it veils all faces, and bows all forms alike, and sends the same shudder through the frame, and casts the same darkness upon the walls, and peals forth in the same dirge of maternal agony by the dead boy's cradle in the sumptuous chamber, and the baby's last sleep on its bed of straw. And Death! how wonderfully it makes them all alike who in the street wore such various garments, and had such distinct aims, and were whirled apart in such different orbits! Ah! our essential humanity comes out in those composed forms and still features. Those divergent currents have carried them out upon the same placid sea at last; and the same solemn light streams upon the clasped hands and the uplifted faces. We don't mind the drapery so much then. It seems a very superficial matter beside the silent and starless mystery that enfolds them all.

In what I have thus said I do not mean to maintain that outward conditions are nothing. I think they are a great deal; and we do right in striving to improve them; in escaping the evil, and seeking to secure the good that pertains to them. But, I repeat, when we come to the essential humanity, to the real discipline and substance of life, we find the same great features; and so this lesson of the street may help explain the problem suggested by the other; may reconcile each of us to our condition in the crowd, and direct our attention to substantial results.

But, again, the street, with its processions and activities, teaches us that much in human life is merely phenomenal, merely appears. We enter into this truth by a very common train of observation. We know how much is put on purposely for the public gaze, and has no other intention than to be seen; how hollow are many of the smiles, and gay looks, and smooth decencies. And even the complexion of some, with its red and white, is more unsubstantial than all the rest; for it is in danger of being washed away by the first shower. It is strange to meet people whose personal significance in life is that of a shop window exhibiting lace and jewelry; strange to encounter men in whose place we might substitute a well-dressed effigy, and they would hardly be missed. Of course appearances should be attended to, and are good in their place. It is right that we should honor society by our best looks and ways. But it is not merely ridiculous, it is sad, to think how much in the street, where humanity exhibits all its phases, is appearance and but little else.

But dress and manners are not all that is phenomenal in human life. These men and women themselves, this streaming crowd, these brick walls and stately pinnacles, those that pursue and the things that are pursued, are only appearances. It may be profitable for us to stand apart from this multitude, this river of living forms, and think in how short a time it all will have passed away; how short a time since, and it was not! A little while ago, and this rich and populous city was a green island, and our beautiful bay clasped it in its silver arms like an emerald. The wilderness stood here, and the child of the forest thought of it as a prepared abiding place for himself and for his people for ever. The red man has gone; the wild woods have vanished; and these structures, and vehicles, and busy crowds, have come into their places magically, like the new picture in a dissolving view. But are these forms of life, is your presence here or mine, any more substantial than those that have sunk away? Nay, all this splendid civilization, what is it but a sparkling ripple in the calm eternity of God? Dwellings, stores, banks, churches, streets, and the restless multitudes, are but forms of life,—as it were a rack of cloud drifting across the mirror of absolute being. That which seems to you substantial is only spectral. And as the dress of the fop, and the smile of the coquette, is merely an appearance; so the wealth for which men strain in eager chase, and the fabrics which pride builds up, the anvils on which labor strikes its mighty blows, and the body to which so much is devoted, and which absorbs so much care, are but appearances also. While that which may seem to you as a shadow—the spiritual substratum of life, the basis of those spiritual laws which run through all our conditions—is the only abiding substance.

If we only look in this light, my friends, upon the continuous spectacle of human movement and human change, we shall find that "Wisdom... uttereth her voice in the streets." Old as the thought may be, in the rush of the great crowd it will come to us fresh and impressively, that all this is but a form of spiritual and eternal being. A day in the city is like life itself. Out of unconscious slumber into the brilliant morning and the thick activity we come. But, by-and-by, the heaving mass breaks into units, and one by one dissolves into the shadow of the night. Two cities grow up side by side—the city in which men appear, the city into which they vanish; the city whose houses and goods they possess for a little while and then leave behind them, and the city whose white monuments just show us the pinnacles of their estates in the eternal world. The busy, diversified crowd that rolls through the streets—it is only an appearance! It is a ceaseless march of emigration. In a little while, the names in this year's Directory may be read in Greenwood.

But we must not rest with this as the final lesson of the street. It is only the form of Life that is transient and phenomenal; but the Life itself is here, also—here, in these flashing eyes, and heaving breasts, and active limbs. These conditions, however transient, involve the great interest of Humanity; and that lends the deepest significance to these conditions. The interest of Humanity! which gives importance to all it touches, and transforms nature into history; which imparts dignity to the rudest workshop, and the most barren shore, and the humblest grave—this permits us to draw no mean or discouraging conclusions from the achievements and the changes of the multitudes around us. It may do for the skeptic, who sees nothing in existence but these forms of things; who sees nothing but the limited phenomena of our present state, and thinks that includes all; it may do for him to croak over the transitoriness of life, and call it a trivial game. But it is not trivial; and there is no spot where man acts, there is nothing that he does, that is insignificant. Perhaps you have a quick eye for the foibles of people, and can detect their vanities, and meannesses, and laughable conceits. If you employ this gift to correct a bad habit, or expose a falsehood, it is well enough. But if it induces you to look upon things merely with the skill of a satirist, then let me say, there is no "ludicrous side" to life; there is nothing in human conduct that is simply absurd. The least transaction has a moral cast, and every word and act reveals spiritual relations. The interest of man can never be thrown into insignificance by his conditions; these draw interest from him. And, whatever his post in the world, however limited or broad his sphere of observation, for him life is real, and has intense relations. We must not stand so far apart from the crowd as to occupy the position of mere spectators, and regard these men and women as so many mechanical figures in a panorama. We must look through the depths of their experience into their own souls, and through the depths of that experience again upon the world, beholding it as it appears to the beggar, and the lonely woman, and the child of vice and crime, and the hero, and the saint, and as it falls with intense yet diverse refractions upon all these multiform angles of personality. So shall we learn to cherish a solemn and tender interest in the dear humanity around us, and feel the arteries of sympathy which connect it, in all its conditions, with our own hearts. And, as we return homeward from our study of the street, it may be with our irritation, and prejudice, and selfishness softened down; with a larger love flowing out towards the least, and even the worst; realizing the spiritual ties that make us one, and the Infinite Fatherhood that encircles us all; perhaps suggestions will come to us that have been best expressed in the words of the poet—

"Let us move slowly through the street,
Filled with an ever-shifting train,
Amid the sound of steps that beat
The murmuring walks like autumn rain.

"How fast the flitting figures come!
The mild, the fierce, the stony face;
Some bright with thoughtless smiles, and some
Where secret tears have left their trace.
