“We have to describe and to explain a building the upper story of which was erected in the nineteenth century; the ground floor dates from the sixteenth century, and a careful examination of the masonry discloses the fact that it was reconstructed from a dwelling-tower of the eleventh century. In the cellar we discover Roman foundation walls, and under the cellar a filled-in cave, in the floor of which stone tools are found and remnants of glacial fauna in the layers below. That would be a sort of picture of our mental structure.”14
