The mathematic, then, is an art. As such it has its styles and style periods. It is not, as the layman and the philosopher (who is in this matter a layman too) imagine, substantially unalterable, but subject like every art to unnoticed changes form epoch to epoch. The development of the great arts ought never to be treated without an (assuredly not unprofitable) side-glance at contemporary mathematics.
Oswald SpenglerAt last, in the gray dawn of Civilization the fire in the Soul dies down. The dwindling powers rise to one more, half-successful, effort of creation, and produce the Classicism that is common to all dying Cultures. The soul thinks once again, and in Romanticism looks back piteously to its childhood; then finally, weary, reluctant, cold, it loses its desire to be, and, as in Imperial Rome, wishes itself out of the overlong daylight and back in the darkness of protomysticism in the womb of the mother in the grave.
Oswald SpenglerLong, long ago the country bore the country-town and nourished it with her best blood. Now the giant city sucks the country dry, insatiably and incessantly demanding and devouring fresh streams of men, till it wearies and dies in the midst of an almost uninhabited waste of country.
