“The scenes are shifting the great theatre of the world. The act which commenced with the Protestant Reformation is nearly played out, and a wider and deeper change than that effected three centuries ago--a reformation, or rather a revolution of thought, the extremes of which are represented by the intellectual heirs of John of Leyden and of Ignatius Loyola, rather than by those of Luther and of Leo--is waiting to come on, nay, visible behind the scenes to those who have good eyes. Men are beginning, once more, to awake to the fact that matters of belief and of speculation are of absolutely infinite practical importance; and are drawing off from that sunny country ‘where it is always afternoon’--the sleepy hollow of broad indifferentism--to range themselves under their natural banners. Change is in the air. It is whirling feather-heads into all sorts of eccentric orbits, and filling the steadiest with a sense of insecurity. It insists on reopening all questions and asking all institutions, however venerable, by what right they exist, and whether they are, or are not, in harmony with the real or supposed wants of mankind.” Huxley’s services to education were more than his struggle for the recognition of the educational value of science. His own contributions to the science of biology and his able championing of the case which Darwin had made in favor of the hypotheses of evolution did much to place the biological sciences in their present position of preëminence and to aid in placing both education and modern thought upon the basis of a philosophy of evolution. After receiving his degree in medicine, Huxley was appointed to the position of assistant surgeon in the British navy. As he cruised about on the war-ship ‘Rattlesnake,’ he began his studies of marine animals. Darwin, you will remember, had also spent long months on southern seas as government naturalist assigned to the Beagle. During the years that followed each had risen to a high position as a British scientist, conducting research, publishing papers, making new discoveries, all of which contributed to make the nineteenth century, as John Fiske said, “the century of science.”
