His fame does not depend so much upon his discoveries (although he discovered enough to make hundreds of reputations) as upon his vast and splendid generalizations.
He was to science what Shakespeare was to the drama.
He found, so to speak, the world full of unconnected facts--all portions of a vast system--parts of a great machine; he discovered the connection that each bears to all; put them together, and demonstrated beyond all contradiction that the earth is governed by law.
He knew that to discover the connection of phenomena is the primary aim of all natural investigation. He was infinitely practical.
Origin and destiny were questions with which he had nothing to do.
His surroundings made him what he was.
In accordance with a law not fully comprehended, he was a production of his time.
Great men do not live alone; they are surrounded by the great; they are the instruments used to accomplish the tendencies of their generation; they fulfill the prophecies of their age.
Nearly all of the scientific men of the eighteenth century had the same idea entertained by Humboldt, but most of them in a dim and confused way. There was, however, a general belief among the intelligent that the world is governed by law, and that there really exists a connection between all facts, _or that all facts are simply the different aspects of a general fact_, and that the task of science is to discover this connection; to comprehend this general fact or to announce the laws of things.
Germany was full of thought, and her universities swarmed with philosophers and grand thinkers in every department of knowledge.
Humboldt was the friend and companion of the greatest poets, historians, philologists, artists, statesmen, critics, and logicians of his time.
He was the companion of Schiller, who believed that man would be regenerated through the influence of the Beautiful; of Goethe, the grand patriarch of German literature; of Weiland, who has been called the Voltaire of Germany; of Herder, who wrote the outlines of a philosophical history of man; of Kotzebue, who lived in the world of romance; of Schleiermacher, the pantheist; of Schlegel, who gave to his countrymen the enchanted realm of Shakespeare; of the sublime Kant, author of the first work published in Germany on Pure Reason; of Fichte, the infinite idealist; of Schopenhauer, the European Buddhist who followed the great Gautama to the painless and dreamless Nirwana, and of hundreds of others, whose names are familiar to and honored by the scientific world.
The German mind had been grandly roused from the long lethargy of the dark ages of ignorance, fear, and faith. Guided by the holy light of reason, every department of knowledge was investigated, enriched and ill.u.s.trated.
Humboldt breathed the atmosphere of investigation; old ideas were abandoned; old creeds, hallowed by centuries, were thrown aside; thought became courageous; the athlete, Reason, challenged to mortal combat the monsters of superst.i.tion.
No wonder that under these influences Humboldt formed the great purpose of presenting to the world a picture of Nature, in order that men might, for the first time, behold the face of their Mother.
Europe becoming too small for his genius, he visited the tropics in the new world, where in the most circ.u.mscribed limits he could find the greatest number of plants, of animals, and the greatest diversity of climate, that he might ascertain the laws governing the production and distribution of plants, animals and men, and the effects of climate upon them all. He sailed along the gigantic Amazon--the mysterious Orinoco--traversed the Pampas--climbed the Andes until he stood upon the crags of Chimborazo, more than eighteen thousand feet above the level of the sea, and climbed on until blood flowed from his eyes and lips.
For nearly five years he pursued his investigations in the new world, accompanied by the intrepid Bonpland. Nothing escaped his attention. He was the best intellectual organ of these new revelations of science. He was calm, reflective and eloquent; filled with a sense of the beautiful, and the love of truth. His collections were immense, and valuable beyond calculation to every science. He endured innumerable hardships, braved countless dangers in unknown and savage lands, and exhausted his fortune for the advancement of true learning.
Upon his return to Europe he was hailed as the second Columbus; as the scientific discoverer of America; as the revealer of a new world; as the great demonstrator of the sublime truth, that the universe is governed by law.
I have seen a picture of the old man, sitting upon a mountain side--above him the eternal snow--below, the smiling valley of the tropics, filled with vine and palm; his chin upon his breast, his eyes deep, thoughtful and calm--his forehead majestic--grander than the mountain upon which he sat--crowned with the snow of his whitened hair, he looked the intellectual autocrat of this world.
Not satisfied with his discoveries in America, he crossed the steppes of Asia, the wastes of Siberia, the great Ural range, adding to the knowledge of mankind at every step. His energy acknowledged no obstacle, his life knew no leisure; every day was filled with labor and with thought.
He was one of the apostles of science, and he served his divine master with a self-sacrificing zeal that knew no abatement; with an ardor that constantly increased, and with a devotion unwavering and constant as the polar star.
In order that the people at large might have the benefit of his numerous discoveries, and his vast knowledge, he delivered at Berlin a course of lectures, consisting of sixty-one free addresses, upon the following subjects:
Five, upon the nature and limits of physical geography.
Three, were devoted to a history of science.
Two, to inducements to a study of natural science.
Sixteen, on the heavens.
Five, on the form, density, latent heat, and magnetic power of the earth, and to the polar light.
Four, were on the nature of the crust of the earth, on hot springs earthquakes, and volcanoes.
Two, on mountains and the type of their formation.
Two, on the form of the earth"s surface, on the connection of continents, and the elevation of soil over ravines.
Three, on the sea as a globular fluid surrounding the earth.
Ten, on the atmosphere as an elastic fluid surrounding the earth, and on the distribution of heat.
One, on the geographic distribution of organ ized matter in general.
Three, on the geography of plants.
Three, on the geography of animals, and
Two, on the races of men.
These lectures are what is known as the Cosmos, and present a scientific picture of the world--of infinite diversity in unity--of ceaseless motion in the eternal grasp of law.
These lectures contain the result of his investigation, observation, and experience; they furnish the connection between phenomena; they disclose some of the changes through which the earth has pa.s.sed in the countless ages; the history of vegetation, animals and men, the effects of climate upon individuals and nations, the relation we sustain to other worlds, and demonstrate that all phenomena, whether insignificant or grand, exist in accordance with inexorable law.
There are some truths, however, that we never should forget: Superst.i.tion has always been the relentless enemy of science; faith has been a hater of demonstration; hypocrisy has been sincere only in its dread of truth, and all religions are inconsistent with mental freedom.
Since the murder of Hypatia in the fifth century, when the polished blade of Greek philosophy was broken by the club of ignorant Catholicism, until to-day, superst.i.tion has detested every effort of reason.
It is almost impossible to conceive of the completeness of the victory that the church achieved over philosophy. For ages science was utterly ignored; thought was a poor slave; an ignorant priest was master of the world; faith put out the eyes of the soul; the reason was a trembling coward; the imagination was set on fire of h.e.l.l; every human feeling was sought to be suppressed; love was considered infinitely sinful; pleasure was the road to eternal fire, and G.o.d was supposed to be happy only when his children were miserable. The world was governed by an Almighty"s whim; prayers could change the order of things, halt the grand procession of nature, could produce rain, avert pestilence, famine and death in all its forms. There was no idea of the certain; all depended upon divine pleasure or displeasure rather; heaven was full of inconsistent malevolence, and earth of ignorance. Everything was done to appease the divine wrath; every public calamity was caused by the sins of the people; by a failure to pay t.i.thes, or for having, even in secret, felt a disrespect for a priest. To the poor mult.i.tude, the earth was a kind of enchanted forest, full of demons ready to devour, and theological serpents lurking with infinite power to fascinate and torture the unhappy and impotent soul. Life to them was a dim and mysterious labyrinth, in which they wandered weary, and lost, guided by priests as bewildered as themselves, without knowing that at every step the Ariadne of reason offered them the long lost clue.
The very heavens were full of death; the lightning was regarded as the glittering vengeance of G.o.d, and the earth was thick with snares for the unwary feet of man. The soul was supposed to be crowded with the wild beasts of desire; the heart to be totally corrupt, prompting only to crime; virtues were regarded as deadly sins in disguise; there was a continual warfare being waged between the Deity and the Devil, for the possession of every soul; the latter generally being considered victorious. The flood, the tornado, the volcano, were all evidences of the displeasure of heaven, and the sinfulness of man. The blight that withered, the frost that blackened, the earthquake that devoured, were the messengers of the Creator.
The world was governed by Fear.
Against all the evils of nature, there was known only the defence of prayer, of fasting, of credulity, and devotion. _Man in his helplessness endeavored to soften the heart of G.o.d_. The faces of the mult.i.tude were blanched with fear, and wet with tears; they were the prey of hypocrites, kings and priests.
My heart bleeds when I contemplate the sufferings endured by the millions now dead; of those who lived when the world appeared to be insane; when the heavens were filled with an infinite Horror who s.n.a.t.c.hed babes with dimpled hands and rosy cheeks from the white b.r.e.a.s.t.s of mothers, and dashed them into an abyss of eternal flame.
Slowly, beautifully, like the coming of the dawn, came the grand truth, that the universe is governed by law; that disease fastens itself upon the good and upon the bad; that the tornado cannot be stopped by counting beads; that the rushing lava pauses not for bended knees, the lightning for clasped and uplifted hands, nor the cruel waves of the sea for prayer; that paying t.i.thes causes, rather than prevents famine; that pleasure is not sin; that happiness is the only good; that demons and G.o.ds exist only in the imagination; that faith is a lullaby sung to put the soul to sleep; that devotion is a bribe that fear offers to supposed power; that offering rewards in another world for obedience in this, is simply buying a soul on credit; that knowledge consists in ascertaining the laws of nature, and that wisdom is the science of happiness. Slowly, grandly, beautifully, these truths are dawning upon mankind.
From Copernicus we learned that this earth is only a grain of sand on the infinite sh.o.r.e of the universe; that everywhere we are surrounded by shining worlds vastly greater than our own, all moving and existing in accordance with law. True, the earth began to grow small, but man began to grow great.
The moment the fact was, established that other worlds are governed by law, it was only natural to conclude that our little world was also under its dominion. The old theological method of accounting for physical phenomena by the pleasure and displeasure of the Deity was, by the intellectual, abandoned. They found that disease, death, life, thought, heat, cold, the seasons, the winds, the dreams of man, the instinct of animals,--in short, that all physical and mental phenomena are governed by law, absolute, eternal and inexorable.
Let it be understood that by the term Law is meant the same invariable relations of succession and resemblance predicated of all facts springing from like conditions. Law is a fact--not a cause. It is a fact, that like conditions produce like results: this fact is Law. When we say that the universe is governed by law, we mean that this fact, called law, is incapable of change; that it is, has been, and forever will be, the same inexorable, immutable Fact, inseparable from all phenomena. Law, in this sense, was not enacted or made. It could not have been otherwise than as it is. That which necessarily exists has no creator.
Only a few years ago this earth was considered the real center of the universe; all the stars were supposed to revolve around this insignificant atom. The German mind, more than any other, has done away with this piece of egotism. Purbach and Mullerus, in the fifteenth century, contributed most to the advancement of astronomy in their day.
To the latter, the world is indebted for the introduction of decimal fractions, which completed our arithmetical notation, and formed the second of the three steps by which, in modern times, the science of numbers has been so greatly improved; and yet, both of these men believed in the most childish absurdities, at least in enough of them, to die without their orthodoxy having ever been suspected.
