"I once asked Prince Kropotkin, the Russian nihilist, how he endured his long years in prison, deprived of books, pen, ink, and paper. “Ah,” he said, “I thought out many questions on which I had a deep interest. In the pursuit of an idea I took no note of time. When tired of solving knotty problems I recited all the beautiful passages in prose or verse I had ever learned. I became acquainted with my self and my own resources. I had a world of my own, a vast empire, that no Russian jailor or Czar could invade.” Such is the value of liberal thought and broad culture when shut from all human companionship, bringing comfort and sunshine within even the four walls of a prison cell. As women ofttimes share a similar fate, should they not have all the consolation that the most liberal education can give?"
