We are of the earth very earthy, and we are not satisfied with contemplating the Invisible God. Somehow or other we want something which we can touch, something which we can see, something before which we can kneel down. It does not matter whether it is a book, or an empty stone building, or a stone building inhabited by numerous figures. A book will satisfy some, an empty building will satisfy some others, and many others will not be satisfied unless they see something inhabiting these empty buildings.
