NATURAL SCIENCE

Later, when Alexandria became the center of the Greek world, and the limitations of metaphysics had become somewhat more evident, there was a return to positive science. For nearly a thousand years men, notably Aristarchus, Eratosthenes, Hipparchus, Euclid, Hero, and Ptolemy, labored at Alexandria, employing the true methods of science and collecting valuable stores of information in astronomy, geometry, trigonometry, optics, heat, and even anatomy. The greatest of the scientific work of antiquity was done during the Alexandrine period by Archimedes at Syracuse. It consists in the creation of the science of statics.

The Romans, practical men—according to Disraeli's definition, those who practice the errors of their forefathers—did little to advance the sciences, and, when the dark ages extinguished all intellectual endeavor, it was little enough that men had achieved in science, compared with their other deeds.

Yet it is certain that both true science and the true methods of science had been established in antiquity. It was not so much the errors of the ancient world as the errors of the Middle Ages in interpretation of the ancient world, and the undue importance that was assigned to Aristotle, which held back science during the first centuries of the Renaissance.

On the other hand, it cannot be denied that if the science of antiquity at its best, in the mechanics of Archimedes, the descriptive astronomy of Hipparchus, the geometry of Euclid, and the zoology of Aristotle, did manifest most of the characteristics of method and treatment which we know to-day, nearly all of the results of modern science, the modifications of life and civilization, are lacking in antiquity. Ancient science was in great part sterile; modern science is now the principal agent in social evolution.


RISE OF MODERN SCIENCE

It was not until the seventeenth century that modern science gained a secure footing. Just as in antiquity, the minds of men once more
