They sent a million here:
Here men were drunk like water, burnt like wood.
The fat of good
And evil, the breast’s star of hope
Were rendered into soap.”

Foremost among the stabilizing factors, more enduring than customs, manners and traditions, are the legal systems that regulate our life in the world and our daily affairs with each other.”
