It is needless to point out in what, or why, the Greeks failed, since here there is question only of intellectual life, and in this they did not fail. Nor is there any thought, in what has here been said, of depreciating the worth of the study of science, without a certain knowledge of which no one, in this age, can in any true sense, be called educated. Whoever, indeed, learns a language properly, acquires scientific knowledge; and the Greeks are not only the masters in poetry and eloquence, they are also the guides to the right use of reason and to scientific method, and the teachers of mathematics, logic, and physics. He who pursues culture, in the Greek spirit, who desires to see things as they are, to know the best that has been thought and done by men, will fear nothing so much as the exclusion of any truth, and he will be anxious to acquaint himself not only with the method, but as far as possible with the facts, of physical science. Still he perceives that however great the value of natural knowledge may be, it is, as an instrument of culture, inferior to literature. We are educated by what calls forth in us love and admiration, by what creates the exalted mood and the steadfast purpose. In bowing with reverence to what is above us, we are uplifted. When we are moved, we are more alive; we are stronger, tenderer, nobler. Now to look upon Nature with the detective eye of the man of science is to be cold and unsympathetic; to learn by methodic experiment is to gain knowledge, which, since it is only remotely or indirectly related to life, is but little interesting. Such knowledge is a fragment, and a fragment extremely difficult to fit into the temple built by thought and love, by hope and imagination; and hence when we have learned a great deal about chemical elements, geologic epochs, correlation of forces, and sidereal spaces, we are rather astonished than enlightened. We are brought into the presence of a world which is not that of the senses, nor yet that which faith, hope, and love forebode; and the bearing it may have upon human life is of more interest to us than the facts made known. We are, indeed, curious to know whatever may, with any certainty, be told us of atoms and biogenesis; but our real concern is to learn what significance such truth may have in its relation to questions of God and the soul.
