The lame rides a horse
the maimed drives the herd
the deaf is brave in battle.
A man is better
blind than buried.
A dead man is deft at nothing.

This poem comes from the Viking Havamal. It shows a recognition of the value of human diversity that seems sadly lacking from the modern world. Perhaps, when people struggle against a hostile environment and really need to work together to build a common world, then perhaps they are little more thankful for each human good and little more mindful of the need to ensure that each one of us has a place – a place where we can play a fruitful role.
