Fortunately for education, science no longer has to fight for its inclusion among the courses offered for study in colleges and universities. As scientific knowledge increases and the technique of teaching science improves, the exact knowledge of the few more rapidly becomes the accepted knowledge of the many. More than that, the scientific attitude of mind produces many of the virtues which in old-fashioned courses in ethics were taught as objectively as a problem in geometry. Patience, endurance, humility, teachableness, honesty, accuracy--without these it is impossible for a scientist properly to work. And the history of science is as inspiring in its human values as are the legends of the saints. Contemplate the heroism of a Galileo, the patience of a Darwin, the humility of a Pasteur; a modern eleventh chapter of _Hebrews_ might be written listing the names of all those men of faith who by quiet work, unremitting in their zeal, one by one discovered facts which have made man’s lot easier and happier in what was otherwise to him a hostile and unhappy universe. Little by little, accretion upon accretion, man’s knowledge of the physical forces of his universe has been increased, but his progress has often been retarded by those who, with good intentions, superstitiously feared the power of the gods who, as in the story of Brunhilde, encircled their mysteries with a ring of fire. Periodically superstition re-arises, but it does not permanently halt the advance deploy of armed skirmishers, however much it may temporarily retard the advancement of knowledge. Since the seventeenth century, however, so remarkable has been the progress of science, so evident have been its beneficent achievements, that regardless of the present assault upon one phase of science, western civilization is committed to this way of discovery. But it is no easy way! “The rapid increase of natural knowledge,” wrote Thomas Henry Huxley, “which is the chief characteristic of our age, is affected in various ways. The main army of science moves to the conquest of the new worlds slowly and surely, nor ever cedes an inch of the territory gained. But the advance is covered and facilitated by the ceaseless activity of clouds of light troops provided with a weapon--always efficient, if not always an arm of precision--the scientific imagination. It is the business of these _enfants perdus_ of science to make raids into the realms of ignorance wherever they see, or think they see, a chance; and cheerfully to accept defeat, or it may be annihilation, as the reward of error. Unfortunately the public, which watches the progress of the campaign, too often mistakes a dashing incursion ... for a forward movement of the main body; fondly imagining that the strategic movement to the rear, which occasionally follows, indicates a battle lost by science.”
