I'm reminded of a science fiction story I read long ago. A group of space explorers discovers an enormous metallic sphere. They open a port in its side and climb down a ladder. They discover that the whole of the interior is a vast machine, far beyond their capacity to understand. The last man out before the port is closed accidentally drops a wrench. They listen to it clatter down beyond earshot.

"Science is one thing, wisdom is another. Science is an edged tool, with which men play like children, and cut their own fingers." — Sir Arthur Eddington
