His life may not have been materially lengthened, but, in the march of knowledge, a year now is as a century, compared with man's progress in the darkness of the middle ages. The eternal advance toward omniscience goes on, but is like that of the infinite approach of the asymptote, which never reaches the hyperbolic curve. The onward of science is in a geometrical ratio, so that in time, the intellectual progress of a day in the future, must exceed that of a century in the past. Knowledge is enthroned as king, and grand truths and new ideas are his ministers. Science takes the diameter of the earth's orbit as a base line and unit of measurement, and with it spans immensity, and triangulates the nebulous systems amid the shadowy verges of receding space. Its researches are cosmical upon the earth and the heavens, and all the elements minister to its progress. Sink to the lowest mine, or fathom the ocean's depth, or climb the loftiest mountains, or career through the heavens on silken wings, and it is there also. On--on--on; nearer--nearer--still nearer it moves forever and forever, with accelerated speed, toward the infinite eternal. Such are the triumphs of knowledge; and he who diffuses it among our race, or discovers and disseminates new truths, advances man nearer to his Creator; he exalts the whole race; he elevates it in the scale of being, and raises it into higher and still higher spheres. It is science that marks the speed of sound and light and lightning, calculates the eclipses, catalogues the stars, maps the heavens, and follows, for centuries of the past and the future, the comet's course. It explores the animal, vegetable, and mineral kingdoms. With geology, it notes the earthquake upheaval of mountains, and, with mineralogy, the laws of crystallization. With chemistry, it analyzes, decomposes, and compounds the elements. If, like Canute, it cannot arrest the tidal wave, it is subjecting it to laws and formulas. Taking the sunbeam for its pencil, it heliographs man's own image, and the scenery of the earth and the heavens. Has science any limits or horizon? Can it ever penetrate the soul of man, and reveal the mystery of his existence and destiny? It is certainly exploring the facts of sociology, arranging and generalizing them, and deducing laws.
