Quote:
"Esperanto is the auxiliary language created by a Polish oculist, Dr. L. L. Zamanhof (1859-1917), and first published in 1887 ... His contention was, that we must first find some solution to the "language problem". Not until we have settled this comparatively minor matter can we begin to understand each other across the frontiers and then to discuss the grave social and economic problems which face us. Esperanto is intended as a simple second language for all mankind..."(from the Introductory Lesson)
