Sometimes it has happened that the brave deed of a single patriot has rallied wavering hosts, flashed the lightning through the centuries, and kindled whole nations into a holy enthusiasm. The opposing legions of soldiers and inquisitors went down before the heroism of the early church as darkness flees before the advancing sunshine. Society admires the scholar, but man loves the hero. Wisdom shines, but bravery inspires and lifts. Though centuries have passed, these noble deeds still nourish man's bravery and endurance. It was not given to these leaders to enter into the fruits of their labors. Vicariously they died. With a few exceptions, their very names remain unknown. But let us hasten to confess that their vicarious suffering stayed the onset of despotism and achieved our liberty. They ransomed us from serfdom and bought our liberty with a great price. Compared to those, our bravest deeds do seem but brambles to the oaks at whose feet they grow.
Having made much of the principles of the solidarity of society, science is now engaged in emphasizing the principle of vicarious service and suffering. The consecrated blood of yesterday is seen to be the social and spiritual capital of to-day. Indeed, the civil, intellectual and religious freedom and hope of our age are only the moral courage and suffering of past ages, reappearing under new and resplendent forms. The social vines that shelter us, the civic bough whose clusters feed us, all spring out of ancient graves. The red currents of sacrifice and the tides of the heart have nourished these social growths and made their blossoms crimson and brilliant. Nor could these treasures have been gained otherwise. Nature grants no free favors. Every wise law, institution and custom must be paid for with corresponding treasure. Thought itself takes toll from the brain. To be loved is good, indeed; but love must be paid for with toil, endurance, sacrifice—fuel that feeds love's flame.
Generous giving to-day is a great joy; but it is made possible only by years of thrift and economy. The wine costs the clusters. The linen costs the flax. The furniture costs the forests. The heat in the house costs the coal in the cellar. Wealth costs much toil and sweat by day. Wisdom costs much study and long vigils by night. Leadership costs instant and untiring pains and service. Character costs the long, fierce conflict with vice and sin. When Keats, walking in the rose garden, saw the ground under the bushes all covered with pink petals, he exclaimed; "Next year the roses should be very red!" When Aeneas tore the bough from the myrtle tree, Virgil says the tree exuded blood. But this is only a poet's way of saying that civilization is a tree that is nourished, not by rain and snow, but by the tears and blood of the patriots and prophets of yesterday.
Fortunately, in manifold ways, nature and life witness to the universality of vicarious service and suffering. Indeed, the very basis of the doctrine of evolution is the fact that the life of the higher rests upon the death of the lower. The astronomers tell us that the sun ripens our harvests by burning itself up. Each golden sheaf, each orange bough, each bunch of figs, costs the sun thousands of tons of carbon. Geike, the geologist, shows us that the valleys grow rich and deep with soil through the mountains, growing bare and being denuded of their treasure. Beholding the valleys of France and the plains of Italy all gilded with corn and fragrant with deep grass, where the violets and buttercups wave and toss in the summer wind, travelers often forget that the beauty of the plains was bought, at a great price, by the bareness of the mountains. For these mountains are in reality vast compost heaps, nature's stores of powerful stimulants. Daily the heat swells the flakes of granite; daily the frost splits them; daily the rains dissolve the crushed stone into an impalpable dust; daily the floods sweep the rich mineral foods down into the starving valleys. Thus the glory of the mountains is not alone their majesty of endurance, but also their patient, passionate beneficence as they pour forth all their treasures to feed richness to the pastures, to wreathe with beauty each distant vale and glen, to nourish all waving harvest fields. This death of the mineral is the life of the vegetable.
If now we descend from the mountains to explore the secrets of the sea, Maury and Guyot show us the isles where palm trees wave and man builds his homes and cities midst rich tropic fruits. There scientists find that the coral islands were reared above the waves by myriads of living creatures that died vicariously that man might live. And everywhere nature exhibits the same sacrificial principle. Our treasures of coal mean that vast forests have risen and fallen again for our factories and furnaces. Nobody is richer until somebody is poorer. Evermore the vicarious exchange is going on. The rock decays and feeds the moss and lichen. The moss decays to feed the shrub. The shrub perishes that the tree may have food and growth. The leaves of the tree fall that its boughs may blossom and bear fruit. The seeds ripen to serve the birds singing in all the boughs. The fruit falls to be food for man. The harvests lend man strength for his commerce, his government, his culture and conscience. The lower dies vicariously that the higher may live. Thus nature achieves her gifts only through vast expenditures.
It is said that each of the new guns for the navy costs $100,000. But the gun survives only a hundred explosions, so that every shot costs $1,000. Tyndall tells us that each drop of water sheathes electric power sufficient to charge 100,000 Leyden jars and blow the Houses of Parliament to atoms. Farraday amazes us by his statement of the energy required to embroider a violet or produce a strawberry. To untwist the sunbeam and extract the rich strawberry red, to refine the sugar, and mix its flavor, represents heat sufficient to run an engine from Liverpool to London or from Chicago to Detroit. But because nature does her work noiselessly we must not forget that each of her gifts also involves tremendous expenditure.
This law of vicarious service holds equally in the intellectual world. The author buys his poem or song with his life-blood. While traveling north from London midst a heavy snow-storm, Lord Bacon descended from his coach to stuff a fowl with snow to determine whether or not ice would preserve flesh. With his life the philosopher purchased for us the principle that does so much to preserve our fruits and foods through the summer's heat and lend us happiness and comfort. And Pascal, whose thoughts are the seeds that have sown many a mental life with harvests, bought his splendid ideas by burning up his brain. The professors who guided and loved him knew that the boy would soon be gone, just as those who light a candle in the evening know that the light, burning fast, will soon flicker out in the deep socket. One of our scientists foretells the time when, by the higher mathematics, it will be possible to compute how many brain cells must be torn down to earn a given sum of money; how much vital force each Sir William Jones must give in exchange for one of his forty languages and dialects; what percentage of the original vital force will be consumed in experiencing each new pleasure, or surmounting each new pain; how much nerve treasure it takes to conquer each temptation or endure each self-sacrifice. Too often society forgets that the song, law or reform has cost the health and life of the giver. Tradition says that, through much study, the Iliad cost Homer his eyes. There is strange meaning in the fact that Dante's face was plowed deep with study and suffering and written all over with the literature of sorrow.
To gain his vision of the hills of Paradise, Milton lost his vision of earth's beauteous sights and scenes. In explanation of the early death of Raphael and Burns, Keats and Shelley, it has been said that few great men who are poor have lived to see forty. They bought their greatness with life itself. A few short years ago there lived in a western state a boy who came up to his young manhood with a great, deep passion for the plants and shrubs. While other boys loved the din and bustle of the city, or lingered long in the library, or turned eager feet toward the forum, this youth plunged into the fields and forests, and with a lover's passion for his noble mistress gave himself to roots and seeds and flowers. While he was still a child he would tell on what day in March the first violet bloomed; when the first snowdrop came, and, going back through his years, could tell the very day in spring when the first robin sang near his window. Soon the boy's collection of plants appealed to the wonder of scholars. A little later students from foreign countries began to send him strange flowers from Japan and seeds from India. One midnight while he was lingering o'er his books, suddenly the white page before him was as red with his life-blood as the rose that lay beside his hand. And when, after two years in Colorado, friends bore his body up the side of the mountains he so dearly loved, no scholar in all our land left so full a collection and exposition of the flowers of that distant state as did this dying boy. His study and wisdom made all to be his debtors. But he bought his wisdom with thirty years of health and happiness. We are rich only because the young scholar, with his glorious future, for our sakes made himself poor.
Our social treasure also is the result of vicarious service and suffering. Sailing along the New England coasts, one man's craft strikes a rock and goes to the bottom. But where his boat sank there the state lifts a danger signal, and henceforth, avoiding that rock, whole fleets are saved. One traveler makes his way through the forest and is lost. Afterward other pilgrims avoid that way. Experimenting with the strange root or acid or chemical, the scholar is poisoned and dies. Taught by his agonies, others learn to avoid that danger.
Only a few centuries ago the liberty of thought was unknown. All lips were padlocked. The public criticism of a baron meant the confiscation of the peasant's land; the criticism of the pope meant the dungeon; the criticism of the king meant death. Now all are free to think for themselves, to sift all knowledge and public teachings, to cast away the chaff and to save the precious wheat. But to buy this freedom blood has flowed like rivers and tears have been too cheap to count.
