We live so much of our lives in chaos. Human history can be viewed as an endless search for greater order: everything from language to religion to law to science tries to impose a framework on chaotic existence. The existentialists, sometimes wrongly described as disbelieving in an underlying order, saw the risks and the foolishness of the obsession with creating one. Hitler showed the risk, as did any number of populist tyrants before him. I teach my students that law, too, shows the risk, when we try to regulate a phenomenon-human behavior-that we do not even understand. I am not arguing against law...but against the Panglossian assumption that we can ever do law particularly well. The darkness in which we live dooms us to do it badly.
