When my professional life is going well it consists of reading and writing appellate briefs. Fortunately, this is not nearly as pathetic as it sounds.
At its most basic, an appellate briefs is a written argument presented to a court explaining the claims of your client and how those claims are supported by the law. As such, it represents one of the great triumphs of human civilization. I am serious. Law rests on a basic commitment to resolving the disputes of human life by resort to reason rather than violence. In the days before appellate briefs (or something like them) we resolved disputes through blood feuds, trial by combat, or by throwing women into ponds to see if they floated. Deliciously dry and intricate arguments about precedent, controlling authority, pleading, and statutory construction represent one of the few unequivocal leaps forward in human history. Post-modernism, historical relativism, and skepticism of Whig history all have their place, but at the end of the day, the rule of law is simply a lot better than trial by combat. Generally speaking, the progress of reason is told in Enlightenment terms as a story about the ebb of faith down the shingles of Dover Beach. However, it is possible to see the triumph of reason in the brief in terms of an older vision of reason: The trace of the divine.
