which followed intellectual command of the secrets of nature. The wonderful transformation of production and distribution known as the industrial revolution is the fruit of experimental science. Railways, steamboats, electric motors, telephone and telegraph, automobiles, aëroplanes and dirigibles are conspicuous evidences of the application of science in life. But none of them would be of much importance without the thousands of less sensational inventions by means of which natural science has been rendered tributary to our daily life.
It must be admitted that to a considerable extent the progress thus procured has been only technical: it has provided more efficient means for satisfying preëxistent desires, rather than modified the quality of human purposes. There is, for example, no modern civilization which is the equal of Greek culture in all respects. Science is still too recent to have been absorbed into imaginative and emotional disposition. Men move more swiftly and surely to the realization of their ends, but their ends too largely remain what they were prior to scientific enlightenment. This fact places upon education the responsibility of using science in a way to modify the habitual attitude of imagination and feeling, not leave it just an extension of our physical arms and legs.
The advance of science has already modified men's thoughts of the purposes and goods of life to a sufficient extent to give some idea of the nature of this responsibility and the ways of meeting it. Science taking effect in human activity has broken down physical barriers which formerly separated men; it has immensely widened the area of intercourse. It has brought about interdependence of interests on an enormous scale. It has brought with it an established conviction of the possibility of control of nature in the interests of mankind and thus has led men to look to the future, instead of the past. The coincidence of the ideal of progress with the advance of science is not a mere coincidence. Before this advance men
