Stones, all stones, are either arranged in some sort of pattern, or they are not. They are either made into something by some intelligent being or they are not. There is no in between.
Walls, paths, buildings, bridges, monuments, fireplaces, tombs, standing stones, even balanced stones, have all had some sort of 'thinking hands' on them forming them into a recognizably ordered state, no matter how indecipherable their purpose or meaning.
But are we missing something? Is it possible the different shaped stones all around this long flat rectangular stone found lying on the beach near Caithness are as 'ordered' as the similar shaped stones placed parallel to each other on top of it?
