The receding depths of time and space, though they can indeed be haltingly conceived even by primitive minds, cannot be imagined save by beings of a more ample nature. A panorama of mountains appears to naive vision almost as a flat picture, and the starry void is a roof pricked with light. Yet in reality, while the immediate terrain could be spanned in an hour’s walking, the sky-line of peaks holds within it plain beyond plain. Similarly with time. While the near past and the near future display within them depth beyond depth, time’s remote immensities are foreshortened into flatness. It is almost inconceivable to simple minds that man’s whole history should be but a moment in the life of the stars, and that remote events should embrace within themselves aeon upon aeon.
