 ... of geometry (I do not speak of those of arithmetic) are merely disguised definitions. Then what are we to think of that question : Is the Euclidean geometry true? It has no meaning. As well ask whether the metric system is true and the old measures...  Studies in Non-Euclidian Geometry - Page 45by Carolyn Soward Armentrout - 1925 - 100 pagesFull view - About this book
