In the antiquated and romantic castle of Tegel, by the side of the pine forest, on the shore of the charming lake, near the beautiful city of Berlin, the great Humboldt, one hundred years ago to-day, was born, and there he was educated after the method suggested by Rousseau--Campe, the philologist and critic, and the intellectual Kunth being his tutors. There he received the impressions that determined his career; there the great idea that the universe is governed by law took possession of his mind, and there he dedicated his life to the demonstration of this sublime truth. He came to the conclusion that the source of man's unhappiness is his ignorance of nature. He longed to give a physical description of the universe--a grand picture of nature; to account for all phenomena; to discover the laws governing the world; to do away with that splendid delusion called special-providence, and to establish the fact that the universe is governed by law. To establish this truth was, and is, of infinite importance to mankind. That fact is the death-knell of superstition; it gives liberty to every soul, annihilates fear, and ushers in the Age of Reason. The object of this illustrious man was to comprehend the phenomena of physical objects in their general connection, and to represent nature as one great whole, moved and animated by internal forces. For this purpose he turned his attention to descriptive botany, traversing distant lands and mountain ranges to ascertain with certainty the geographical distribution of plants. He investigated the laws regulating the differences of temperature and climate, and the changes of the atmosphere. He studied the formation of the earth's crust, explored the deepest mines, ascended the highest mountains, and wandered through the craters of extinct volcanoes. He became thoroughly acquainted with chemistry, with astronomy, with terrestrial magnetism; and as the investigation of one subject leads to all others, for the reason that there is a mutual dependence and a necessary connection between all facts, so Humboldt became acquainted with all the known sciences. 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.
