The law—as was said with resignation of the poor—is always with us. Some twenty centuries before the Christian Era, Hammurabi promulgated his famous code for Babylonia. The Mosaic code of the Israelites is only eight centuries younger. Even before those ancient codes, practices and customs were the equivalent of law, if not true law in the modern sense, among primitive people. Some primitive societies in our own day are still controlled by such amorphous law.
Every legal rule, idea, or norm had its own genesis. All started somewhere and had some cause. Some came about by chance, and thought gave birth to others. Some stemmed from one mans weakness; others were the fruit of strength. Some still echo with the noise of ancient struggles; while passing time and change of custom formed some others.
Today, as ever, law pervades our lives. This is its nature, because law guides our relations with each other. It tells us pay when, by our fault or not, we injure others; it says what we must do if we want our promises to be enforced as contracts; it makes us pay our taxes; it requires us to take out licenses in business, to get married, and even to practice such a pastoral pastime as the art of angling.
